I removed my “old” scrap wood boxes from the sides of my cart, replacing them with some new “wings” for my Makita miter saw. Actually, more like re-purposing. I took the boxes apart and used them for the wings. They were 1×12 material, so gave me the size I wanted.

Here is the left-hand (feed) side:

A 24″ long 1×12 is bolted to the cart (just like the scrap boxes were) using a couple of 1/4″ bolts. To keep things strong and level, I added two 2x4s cut at 45 degree miters. They act as braces for the top. The work surface is another 1×12 standing on a couple of short 2x4s. The 2x4s, with some washers, bring the deck to exactly the same level as the saw.

If I had put the saw on a new deck, I wouldn’t have needed this more complicated setup. However, I was trying to avoid buying more lumber and wanted to re-use what I had on-hand.

Everything is pine, which isn’t exactly the most stable material, but it will do for now. I “finished” the top with a couple of layers of the ever-stinky Johnson’s Paste Wax.

I used the wing for all of my cuts — what a difference it makes! The extra support on the left side is amazingly helpful. And I really don’t lose any space — my scrap can fits right under the wing. This is great, as I can just toss odds and ends right in.

After finishing my cuts, I noticed that I could use some support on the right (out-feed) side. I’ve been playing around with this design:

On this side, I need it to drop / stow out of the way, because I have very little room in the shop (see band saw in right background). So, I attached the wing to the existing handle on the cart. Now I need a way to keep it in place while cutting (right now I’m using a little clamp, visible). Since this is just the out-feed, and I usually use 1x4s, this is a 1×6 piece of pine cut to 24″.

Update: Ye old saw is shifting around on my baker’s cart, throwing off the alignment (and height) of the side wings. Looks like I’m gonna have to build a new platform after all. Ah, well. I’ll make it out of MDF, which is a lot more stable (less likely to warp).
