I have an old Craftsman table saw, model 137.218020, and I’m looking to make a station for it. I haven’t decided if I want to buy a fence and rail system, like the Delta 36-T30 T3 or just make my own. I’ve seen plenty of videos on making my own and it looks like an achievable project. I know I would love the challenge.

Anyway, my question is about the Delta fence. What is the spacing supposed to be between the front and back rail?

My table saw’s table dimensions are 16” wide by 16” deep. However, the front fence rail is cast as part of the table top so if I were to build a structure around the saw, it would actually be 17 1/16” deep.

If I were to decide on using the Delta fence system, how much more table top do I need to add, front to back, so that I could mount the rails and have the fence fit?

Here’s a picture of the saw (not my picture, but one found on this site):

I want to build a table around it and have a fence that will increase the rip capacity to at least 30”. If I make my own, I’m limited only by how big I make the table. If I use a commercially available fence system, I need to know how far apart the rails need to be, as that will tell me how deep to make the table.

Another question would be, am I dreaming if I think I can mount the rails to wood and have an accurate fence?

Thank you in advance for your help.

The Delta T3 requires 27” between the front and back rails. I have one installed on my Cman 113.

I would think if you stabilized everything and it was all perfectly straight and square, you could mount the rails to wood.

Is that 27” exactly or is there some play in there? That would mean I need 10” of extra table, front to back. Which isn’t a bad thing. Just good to know.

It has made me wonder about aftermarket fences. Not every table saw is the same size but I never see the Delta T3 listed for any specific model(s) nor are there any options for which table saw you might own. Do they come with spacers or is that the buyer’s responsibility?

As for mounting to wood, that would be the challenge, i.e. getting it straight.

Yes, my top is 27” exactly. That leaves about 1/8” play to remove the fence if need be.

For your situation, you may have to find a fence that doesn’t clamp in the back. Only on the front rail, something like on the Sawstops.

This thread also has a couple other suggestions, including modifying the T3 for the shorter table.

Yeah, I saw that earlier this morning. Interesting idea. Looks like it worked out nicely, too.

Have your say...
