My current project is a 3-1 cut-off sled from ShopNotes Tools & Jigs. I'm in a debate rather getting the metal runners, (miter bars), or should I make them from 3/4" ply?

Hi Ken

Just my 2 cents I would not use plywood I would use some hardwood or some plastic, something that will hold the edge...for more that 10 mins..

Thanks Bob.

I was hoping to use some spare 3/4 birch ply that I have but looking very seriously at breaking down and getting the metal miter bars.

Hi Ken

That should work ,, But I would one want to use something that is softer material like plastic or hardwood so it can't wear the slot in the table out or out of true..once it wears the slot out of square that's it...but then Alum. should be fine for a long time....but it likes to gull (build up) in the slot up with Alum..many of the old cast iron tables came with a steel guide for the miter and they have been around a long time..and most of them are true..

A little Johnson paste wax goes a long way..

Thanks again Bob.

I just got the Incra miter sliders ordered from Woodcraft. I went with the 24" ones, figured it will help keep the jig tracking true + stability.

Ken, I used poplar for the guide strips on my sleds. It's inexpensive and fairly stable. It has stood up well over the years.

On all my jigs that need slides I use that slippery high density plastic. Can never remember the name of that stuff. Anyway, unlike wood it will never swell or shrink and since it is slippery it will always move nicely. My two cents.

I see you have ordered your sliders Ken, but for anyone else's info, you can get UHMW strips from Peachtree Woodworking Supply, Inc. They even have a special size for Sears saws. My saw takes a .745" slider instead of the .750" Why they didn't make it 3/4" like all others, who knows.

If you do make them from wood, use ply. Wood runners will move over time. When I build a new one, I will use the Incra sliders.

Hi hubert,

To be honest, I had a brain fart and completely forgot about using UHMW.

This is a project for the new TS. If things go well, it will become the main workhorse for jigs per say.

Thanks all.
