Buying Plywood - Cuts, Cores, Matches and More
Buying lumber from a lumber yard can be intimidating, but surely plywood is simpler... right? Plywood is a manufactured product that has a more controlled process and standardization then harvesting lumber, but there are still a lot of variations in plywood that makes buying plywood more complicated then if you were to buy a PlayStation off the shelf.
I don't buy plywood frequently, each time I do I have to refresh myself on all the different terminology and options that I get back from the lumber dealer so I decided to write a post to myself to save my time re-searching the internet on what each thing means.
Core Materials
Face and Back Grades
Face grades:
- AA - Premium, architectural quality for interiors, case goods and high end furniture.
- A - Not as high as AA but still excellent appearance.
- B - Less perfect and consistent than A panels but more economical.
- C - More defects and variations. Not as attractive so good for less visible applications.
- "Shop" grade - Panels that have some imperfection that causes the sheet to not meet the grade (e.g. A1 or C2).
Back grades
Baltic Birch Grades
- B/BB - one face free of "footballs".
- BB/BB - An average of 4 to 6 footballs per face
- BB/CP - An average of 4 to 6 football on one face and unlimited footballs on the back
Veneer Core
MDF Core
MDF core consists of using medium density fiberboard between the face veneers which is very stable and uniform. MDF can be heavy and can swell up and dissolve when wet.Combination Core
Veneer Cuts
Veneer Match
Slip Matching
Sequence Match
Book Matching
Book matching turns the panels over so that two adjacent panels mirrors each other much like how you open a book.References

Workshop Upgrades to Improve Organization and Workflow
Monday, July 17, 2023
My most essential tools for woodworking
When I first started learning woodworking, I watched shows like the New Yankee Workshop and videos on Youtube. I was envious of all the tools and gears that the creators had but over time I realized that I don't work like them or build things the same way they do. The tools that I reach for my projects turned out to be different from what is often shown on the videos. To give another perspective on what are tools to consider for the hobbyist, here are what I use for almost every project.
Used for Every Project
Measuring tape - There's no project that doesn't require some way to do measurements. Even if you are going to buy rather than build, you will need to be able to measure.
Mechanical pencils - I don't recall any project that I've done that didn't require having a pencil to write or mark something. It was so common for me to be searching for a pencil that I ended up buying a bunch of cheap mechanical pencils and having them everywhere so that I don't constantly stop to look for one to write with.
Combination square - I didn't expect this to be my #1 most useful tool for woodworking. You don't usually see it being shown or highlighted in woodworking videos, but this the versatility and usefulness of this understated tool means that I use it for every project. I use it to mark, set repeatable heights, as a straight edge, 45/90 degree finder and a host of other activities. I started with a basic one and eventually knew that if I bought an high end one I'd have no regrets.
Used for Most Projects
Drill & Driver and screw drivers - Most projects will require installing fasteners (e.g. screws) so either a set of screw drivers or a power tool (driver) will be used. A drill is used for drilling holes but can also can drive screws but I prefer having separate drills and drivers.
Woodglue or Screws - Joining things together requires either glue, screws or nails. I don't use nails much so it's either glue or screws for me. For screws, I prefer the square head screws rather than phillips screws but it's not so common to find in US hardware stores. Torx head screws can be found but they might be more expensive.
Saw - Having a saw is very useful. I'd recommend starting with a Japanese handsaw which are less expensive but cuts better (in my opinion). I also find Japanese handsaws to be more versatile then western style handsaw. There are also powered saws such as table saws, track saws, circular saw, etc. Having something to cut with is VERY useful but there are times when I buy materials to size that meant I didn't have to do my own cutting.
Very Useful
Woodworking square - My first "splurge" tool was a Woodpecker woodworking square and I nearly always reach for it at some point when I'm working on a project. I mostly use it to check for square but I also use it to hold things square and check for straightness.
Mallet - I use a rubber mallet a lot more then I use a hammer to avoid marring surfaces when I really need to pound something.

First Cross Cut Sled
I decided make myself a small basic crosscut sled to use with my table saw. YouTube is filled with videos on how to make a crosscut sled ranging from simple to ones with built-in clamps, adjustable kerf openings and many other features. I won't go over how to build the sled as there are enough videos on YouTube to learn from. I will just share what I learned from building the sled.
Not knowing what features I would really need, I didn't want to spend too much time and money on my first sled. I figure that I just need to build one and try it out to see how I would use it.
Making the runners took most amount of time but that might be because I got lucky when setting the fence to be perpendicular from the blade. I put in a screw on one end of the fence so that I can pivot it. Then I used a woodworking square against the fence and saw blade until it was 90 degrees. I clamped down the fence and was prepared to use the 5-cut method to calibrate it but after I found that I was within .001 and .0005 of an inch I decided that was good enough for me!

New Yankee Workshop Now On Youtube!
I just noticed this week that The New Yankee Workshop is now officially on Youtube! The New Yankee Workshop is an iconic woodworking show that ran on PBS for 21 years. The Youtube channel doesn't have all the episodes but even the official website didn't have them all. The only way to get all the episodes was to buy the complete series DVD which costs $3000.
They seem to have a lot of difficulties bringing the episodes online or at least was bringing them online very slowly. As of this writing, the official website has had most of its contents removed and has a message saying they're rebuilding it.

Returning to Woodworking
After many years of doing very little woodworking except to occasionally cut something to size, I dusted off the tools and started to make three pieces of furniture for a small shed. Returning to woodworking re-introduced the three classical problems I always faced: materials, space and organization.
Materials
To build anything requires having materials: wood (plywood and dimensional lumber), fasteners (screws) and finishing.
I'm able to get lumber (1x, 2x clear douglas fir) at a nearby lumber yard easily and they don't take much space. I can fit them into my car once I put the back seat down. The prices on lumber was eye opening. I've read in the news about the soaring prices of lumber due to the pandemic and supply chain issues to until now I've not had to buy much so there was a bit of sticker shock seeing how much lumber cost now.
Plywood is more difficult to get home and are heavy. Fortunately, in the years since I last had to buy plywood, a local company will now deliver to residential addresses. The one downside is that their hours and distance are just enough that its prohibitive to go and check out their inventory first hand. I ordered a few sheets of 3/4", 1/2" and 1/4" Maple. I've been conditioned to go straight to 3/4" plywood for most of my projects but with the cost and sometimes the weight, I realized that using 1/2" can be just as effective. Whereas I previously would've used 3/4" for a dust separator/shop-vac cart, this time I used 1/2" and realized it was actually a better choice.
I keep a stock of various size screws but did not have enough for this project. The online store that I like to order from from were out-of-stock or had long delivery times for what I wanted so I ended up buying some from the lumber yard. I went with GRK fasteners which are more expensive but I heard they are the bee's knees. The heads use Torx (star) recess which are superior to Philips and can be used both indoors and outdoors. I have a personal preference for square heads which I find easier to insert into the head and also easier to figure out the right bit size to use (pretty much #2), but they aren't as common to find locally. I found that I mostly use 1 1/4" and 1 1/2" length #8 screws with the occasional 1".
The last major material I needed is finishing. Basic polyurethane varnish is readily available at the local hardware stores, but for woodworking I've mostly used Gel wipe-on stains and top-coat. They are easy to apply and hard to mess up. The small woodworking shop that I used to buy from had closed and other local places that would normally sell it are out-of-stock so I went online.
In the end, I found that it is easier now to get materials needed but at this particular time the challenges are high prices and supply chain issues.

My Garage Workshop
Everything is against one wall or on wheels so they can be moved against the wall to help conserve space.

Mitre Station in the Workshop
It's essentially just a box with an compartment underneath being used to house the dust collector. The main challenges for the build were making it level since my garage has a pretty steep slope and getting the height right so that the Kapex is at the same height as the workbench. I used shims on the back to and on the front I used some machine levelers to make it easier to adjust the height. I was able to get it even with the workbench.
There is an opening in the back for the hose, power cord and air to flow through.
The other side of the station still need an extension so I'm thinking of building a folding extension that I can pull out whenever I need to use it. Also, some shelving next to the station would be useful and would complete my work space "L".
Dust Collection for Router Table
There is is plastic sheet that sits between the router base and the router table. It has a velcro ring that the blue rubber cup sticks to so the cup doesn't move around. Mount your router and put in the rubber cup and then attach the hose.

Mobile MFT3 Cart with Boom Arm and Storage
The result is this mobile storage cart for my MFT3:
I got a lot of the inspiration from others especially those who posted on the Festool Owners Group. I added a boom arm to hold up the vacuum hose and power cord so they stay out of the way when I'm cutting. There are 3 compartments for storing things in the front and a small storage place in the back as well. The caster are machine leveling casters from WoodRiver which keeps it stable and stationary when, but when I want to move it I can lower the wheel.
Finding a place to keep the saw between cuts has always been a pain so I decided to have space next to the table to put it down. I put in some sides to prevent it from accidentally falling off.
I haven't done too much since building the cart, but I have some projects in mind if only I can find the time... :-)

Latest Shop Addition: Router Table
I used plywood that was left over from another, bought 3 inch casters and spent an afternoon working on it. Compared to how long it took me to build the shoe cabinet, making this cabinet went lightning fast. Having the router table to help create the dado and rabbits definitely made things go much faster.

Straightening Warped Ikea Solid Wood Table Top Part 1
That was my thinking since I wanted to have wood table in the office that can take some abuse, but I don't have the equipment to do it from rough stock. Telling She-Who-Must-Be-Obeyed that I'm going to spend $800 on equipment to build a $100 table won't end pretty so for $79, I picked up the beech wood table top and a few legs.
The table top looks nice, but to my dismay when I opened up the box it was obviously slightly warped. My wife didn't seem to notice but I took out my 4' level and sure enough there was a slight curve around 1/8th of an inch. My first thought was to go exchange it but transporting the sucker is a pain. After some googling, I settled on an "old timer's" method.
Take the table top and put it on grass that is slightly damp during a sunny day with the concave side facing down. This will let one side absorb some moisture and the sun will dry/pull moisture through the other side. The idea is to balance the moisture content in the wood so that it will flatten. After leaving it out for about 3 hours, the wood had indeed flattened. Actually it started to warp a little in the other way so I had to flip it one more time and keep a more careful eye on it.
Once it was flat, I took it into the garage but sometime can up and I had to leave it there for a few hours. When I returned, the table was warped again but not as bad as before. My idea was to sand the table when it was flat so that I can immediately apply some polyurethane varnish to seal the moisture so that it won't warp again, but couldn't get to it in time so it looks like I will have to try this again next weekend.

Some Garage Organization
This is the "workshop" side of the garage. It is still not completely done but right now it allows me to keep stuff somewhere without them getting underfoot.
I need to get some more hooks and I'm planning to add some shelving above the workbench. The floor is pretty sloped and took a lot of shims to get it leveled.

Sandbox with Seating
I built the lids to fold on top of each other so they become a seating bench when opened. It still offers plenty of play area for the kids, easy for them to open while keeping neighborhood animals out.

Plywood and lumber cart.
Thanks to K who sacrificed two afternoons to help me with this project. We put together a sheet goods cart based on the plan in The Complete Book of Woodworking by Tom Carpenter. This design is pretty common and many examples and variations of it can be found through a Google search. I like this particular design because the cuts and assembly are pretty straight forward. Some of the nice things about this cart are:
The plan even had one end of the cart be a clamp carrier, but I decided not build it for now. I can always add it in the future.
Now, a few lessons learned from building this that wasn't really highlighted in the book. One, it's not easy to do this alone. It's possible but will take a lot longer. The cart is very heavy so when the author says to flip it to its side to install the caster it really takes two people.
Two, among the tools needed, I would throw in a nail gun. It helps to hold pieces in place during assembly. It's not essential, but helps a lot.
Three, have a good set of clamps handy. In the book it showed the use of just a couple of quick clamps but have some larger parallel clamps handy since wood isn't precision materials and will not just "fit". The clamps help to hold the pieces together while you screw things together.
I really enjoyed building this especially since the end result is very functional and useful. The garage is a lot less cluttered now and I can actually get access to my materials again!

Festool Domino Review
The Domino can be used where you’d use a biscuit joiner, but provide greater strength. It can make mortises, but it does it in the palm of your hand. It can be used in place of dowels but with the added benefit of not twisting. That already is like having 3 tools in one! When you throw in the Domino tenons there is even greater time savings not having to make your own tenons.
The Domino is well built and feels solid in your hand and I especially like how it is designed so that you can use it with markings instead of measuring. For example, putting a mortise in the middle of a ¾” piece is a matter of just letting the fence rest on the face of the board or using the stops that are already on the tool. Even the accessories allows you to place your mortises where you want them without heavy measuring. I’ve used the Domino from building cabinet doors to simple through slots for holding my chisels and it is easy, quick and accurate.
As good as the Domino is, there are still some small things that I’d like to change. Attaching the dust collector hose can be a pain sometimes. The depth of the mortises is limited pretty much for the tenons so it’s not as general as a mortising machine. The switch to set the mortise width should only be used when the tool is running so why doesn’t it lock when it isn’t on?
Is the Domino worth it? I would recommend it especially if you don’t have biscuit joiner, mortiser, or doweling jig since the price of buying the 3 tools starts to put it close to the Domino. If time is a premium then this makes it worth it too. I was able to build two cabinet doors in 30 minutes (my very first) compared to how long it would’ve taken me to do it otherwise.

First Cabinet: Walnut Shoe Cabinet
It was a good learning experience and overall turned out better then I expected. There are definitely things I want to do better on my next cabinet, but fortunately most of the mistakes on this one isn't visible. Building this cabinet wasn't cheap since the raw materials (solid walnut, walnut ply) are quite expensive (3/4" ply is easily over $100), but for the next cabinet I will have plenty of stock remaining so that will be the savings. If you just needed a single cabinet it's definitely cheaper to just buy one. I also bought the wood that already been smoothed which is very expensive compared to buying rough lumber and planning it yourself. However, I didn't have access to a planner and wasn't ready to buy one.
To cover the plywood edge of the shelves, I went with unfinished edge banding that already have the adhesive on it so I didn't have to iron it on. The solid wood hides the rest of the plywood sides. Finally, I used a poly gel for the finish as I'm not ready yet to use "real" finishes such as shellac.
For the hinges, I went with an European style hinge so that it doesn't show.
(still some sawdust that I need to clean out... ^_^;)
