Add side extensions to table saw

I finally finished up the extension tables for my Delta Shopmaster Tablesaw. I ended up resurfacing the left extensionextention because I didn’t have enough plywood to make it out of wood, but I did finish the right side. Below is a video and quick rundown of the steps I took to build the right extension for the saw which I will later turn into a router table and will build a router lift to go with it.

I started out by cutting everything to length

Next I squared off the stock. I decided to try my hand at using the metric system for this build. I squared everything off to 36mm so I could easily measure out for the tenons and mortis at 12mm

and the complete bridal joint

I had a hard time figuring out how to mark the holes until I thought about marking the face of the bolts with a graphite pencil. This allowed me to mock up the extension table and tap the frame work against the bolt. This left marks I used to drill the holes

Drilled the holes that would bolt to the cast iron table of the saw

I went ahead and resurfaced the left extension because I didn’t have enough plywood to do both sides.

I had to drill two new holes in the frame work of the saw.

This is the second hole

I screwed the top down to the frame work. That way I can easily replace the plywood if it ever gets warped or scratched up too bad.

And here it is…ready to start the addition of the router.
