Making A Table Saw Extension Wing For A Router Lift

Last week I built my quick release router lift and this week I made an extension wing for my table saw to mount the router lift to. If you haven’t already you might want to check out that project before this one as the actual plans for this wing are included as part of the router lift plans. My last router table was built specifically for my last shop. It had a French cleat on the back which allowed it to be mounted to a waste height French cleat on the wall. It worked great in the last shop but in this shop I really didn’t have a decent place to use it. So it just sat and collected dust for the past 6 months.

I previously had a table saw mounted router table but my main issue with it was breaking down the router table setup to use the table saw. With the stop block incorporated into the new router lift that is no longer a problem. So for that reason I decided it would be best to save shop space and put this one back in the table saw. I’m not sure if I have been making projects that don’t utilize a router table because that just happens to be the design outcome or if subliminally I have been designing projects that can be completed with out the use of a router table because in the back of my head I knew I didn’t have one. Either way, completing this should allow me to complete router table tasks much more easily.

I do have plans available for those who are interested in this entire router table setup. The materials cost me about $50 and I picked up a 2HP Drill Master router from Harbor Freight for $39.75 plus tax (using one of their common 25% off coupons). A router table with a router lift and a router for about $100-$110. I’d consider that budget friendly. Detailed plans are available at the bottom of this article.

The extension wing itself continues the theme of the router lift in that the goal was to be super simple. There’s no need to complicate it so it’s just a shallow box. The router lift plan has a cutlist that includes parts for both the extension wing as well as the table fence. Because I already cut these parts in the router lift build all I had to do was assemble.

I often get asked what kind of plywood I am using. For this one, and most of my other shop projects, I used a 11 ply 3/4” Blondewood plywood from the blue store. It’s primed white on one side and I think a natural birch on the other side. While this stuff is a huge step up from cheap pine plywood I do wish I could get a hold of a little better quality plywood for around the same price. I’ve heard good stuff about Purebond plywood so maybe I’ll make a trip up to the orange store one day and get some.

Simple is the name of the game. Just glue and brad nails to complete the box structure.

With the insert plate cut to its final rectangle size I located it on the surface according to the plan and marked the perimeter with a pencil.

And then cut close to the line with a jigsaw to remove the bulk of the interior material.

Previously I used pocket holes to make a guide frame when cutting insert plate holes. For some reason I chose to use double sided tape instead. The tape worked great but unfortunately I was left with a lot of sticky residue that took about an hour to remove with a chisel.

The purpose of the guide frame is to give a reference for the exact perimeter needed for the insert plate. Using a router bit with a guide bearing I could route out the rest of the material leaving a perfect opening for the insert plate to sit in.

The router lift will be mounted to the bottom side of the extension wing. When you drive screws into a material without predrilling the material will mushroom out just a little bit so I predrilled countersunk holes into the top of the router lift. That way after the screw goes through the router lift and starts to go into the extension wing the mushroom that will be formed will have a little bit of expansion room into the countersink thus allowing for a snug connection between the two layers of plywood.

And mounting it to the bottom of the extension wing before it is installed. I made sure to line it up with the dimensions in the plan.

With the factory extension wing removed from the table saw I can transfer the mounting locations to the new extension wing.

And drill the holes. I was actually able to use mounting holes that were much further away from the table saw than the previous wing which helped to evenly distribute the weight of the wing.

Time to install. I was quite pleased at how much of a snug, yet effortless fit it ended up being.

Of course the next step is leveling it to the table saw surface. I didn’t get too crazy with this step. So long as my cheap straight edge says they are coplanar then it’s good enough for me.

An area where this router table system will shine is in dust collection. I’m using a 4” dust collection port to directly hook up to my dust collector. I’ve used this exact dust collection setup in my last two router tables and it is fantastic. It really does a great job at bringing full dust collection right up to the cutting edge of the router.

After a bit of sanding and filing to remove the corners on the insert plate it is fit into the hole.

To precisely locate the center of the router bit I used a 1/4” brad point bit in the router collet. Then the insert plate can be lowered on top of the bit to form an indent right at the correct location.

I used a 1-1/2” diameter forstner bit for the router bit hole. I know I’ll be using different router bit sizes so I can always make more insert plates later to accommodate different bit diameters.

To make the dust collection really efficient a much larger hole is cut behind the router bit hole. This creates an unobstructed path for the dust collection to reach right up to the router bit. The hole in the back is 4” in diameter but it will all be covered by the router fence later.

With the extension wing build and mounted and the insert plate fitting properly I had to call it quits for the day. I ran out of time and I knew the video was getting long. The router fence will be for another day.

  1. Are you planning to have “T-slotted” rails running cross to accommodate feather boards? As you stand in front of router rail would run left to right. Also including into your fence?

  2. Jay, it looks awesome!!! Keep up the good work!!! When I get my table saw, that’s probably the first thing I would do…

  3. Jay – I really like this design. I will probably build it this spring. Question – are you going to use the table saw fence for the router or build a second fence?

  4. How big is the shaft of the Forstner bit?

    Could the blank insert be clamped in place with the Forstner bit in the router and the router then raised to start cutting the hole, before flipping over the insert and finishing off the cut from the other side?

    • The forstner bit shaft is 3/8″ I believe and the collet I had in the router was 1/4″. Spinning the forstner bit with the router would probably do more burning than cutting due to the speed.

      • Yes. the speed would be a problem unless an additional speed control was used to slow down the router sufficiently – and you’d need to “peck” at the insert, withdrawing the bit intermittently, to let both the bit and the router motor cool down.

  5. I have not ordered the plans for your router table insert as yet because I am not sure that I can resize it to fit the opening in my Rigid jobsite saw. The available opening is about 10″ x 20″ with the extension opened and locked. I read that the other users who have made an insert for this saw are able to leave the insert in as long as the fence is locked down on top of the insert since there is no way to fasten it in place. Any thoughts?
