Topic tags/keywords: jig track saw

I know there are a number of other post on this, but I thought I’d join in anyway. I made this track saw earlier this month.

The 5’ track is made of a 1/2” birch plywood base with 3/16” plywood attached. I could have routed a slot in a 3/4” piece as well – I just didn’t have any.

I wanted a dedicated circular saw that I could leave on the base. I found an older Makita at the thrift store for $15. It looked to have hardly been used. This thing is heavy, at it’s all in the motor – so I expect it to last.

I used High-Density-Overlay plywood for the base. It’s really slick, and slides easily on the track. It make a nice zero-clearance set-up for the blade.

I mounted a hardwood guide on the base, parallel with the blade. Glued and screwed.

I used paste-wax in the slot to make the saw slide easy. Gratuitous shot of my wood stove…

I cross-cut this plywood with zero tear-out – good result.

I like projects like this – a couple of hours and it’s done. For the amount if times I’ll use it, I think this is the right tool. If I were a contractor, I’d buy a commercial one – but I can’t justify hundreds of dollars for something I’ll use no more than once a month.

What’s left to do:
- I think I’ll make a second track that’s 3’ long with a perpendicular leg so it has a built-in square. Easy for cutting base cabinet plywood.
- I’m going to add a dust collection port to the outlet that’s already on the saw.
- I would be a good safety feature to have the saw stay up and push it down for each cut – like the commercial ones. I’m going to fiddle with it and see what I can come up with.

Nice work and nice idea. For a novice, a little more info on how you would set up and use the leg on the 3’.

ohtimberwolf,

Thanks and sure. Here is the concept – combination of a track and a square.

Now that is cool. I’d love to have a track saw, or equivalent.

Very nice job.
I made one, the simple kind with a straight strip of wood attached to a wider flat piece, but I like the fact that yours prevents the saw from drifting in either direction. Mine will allow the saw to wander off if you let it slide away from the fence. Gonna build one like yours.

Looks like a great alternative to a track saw. I like the idea of the smaller one but looking at the concept image I couldn’t help but wonder if a t-square style might work as well.

Kenshu,

I thought the same thing about a t-square – then I realized I would cut T-leg off the first time I used it and make it an “L”.

That’s a really slick idea Troy. You might try putting some sort of paste wax on the bottom of that sled. That should really make that thing fly.

Bob – yes that’s exactly what I did – works great.

Be well.

how much depth of cut is sacrificed with this home made track saw accessory?

I made a a straight strip of wood attached to a wider flat piece too.and It got warped so I going to make another one.Think I’m going to make one like yours.How did you line up the “runner” and the blade so they’re parallel?

Toolie – I loose 1/2”. The saw has a 2 1/2” depth of cut, so with the track I get 2”. Way more than I will ever need. I’m not going to be cutting lumber with this thing, only plywood.

daddywoofdawg – here is an easy way to line the two up. Rip a scrap of wood to the distance you want, clamp it to the blade, clamp the runner next to it, glue and screw (or air nail) it. Make sure the scrap wood is not leaning against a blade tooth, but fully flat to the blade. I used 1/4” plywood.

Good luck.

How is the loss in depth of cut only 1/2”? Your track is 1/2”+ 3/16”+ the thickeness of the piece on the saw itself. That’s about 1 3/16” lost correct?

The guide bar for the saw could be mounted directly to the saw base and gain 1/2” of cut capacity. The plywood guide rail would provide the zero clearance.

That’s what I would say reading description and looking at pictures…But still should be plenty of blade depth for plywood.

Nice job!
