Topic tags/keywords: router table miter miter sled question

I’m working on picture frames so I’m only talking about small stock (no bigger than 1×3s) and 45s.

I have a hand-me-down Makita miter saw with a new blade in it. I can set it to a 45 with a good square and get pretty good results- but I’m looking to make easy, repeatable 45s.

I have a router table which I’ve been learning (it’s only a month old). My thought is this, since I don’t have a table saw:

Could I build a miter sled and slide it down the miter groove(like you would on a table saw) using a straight router bit to cut?

I’m thinking tat if I put the effort into making the sled properly I should be able to get repeatable results.

My other option is to buy a junky table saw for this purpose. Any thoughts on this would be greatly appreciated.

I would say use a miter saw or a miter box. Routers aren’t too great for cutting lines.

Depending on the width of your frame stock, there are router bits that will yield a 45. Chamfer bits
You could use your suggested method for the final cut. I wouldn’t attempt to cut the full width stock with a router bit.
A well tuned table saw is a better choice, IMHO.

In theory, sure you could do it. But I think you’d have problems with tearout, and with cutting precisely to the line, as dorran pointed out.

Is it possible to square up a $200 table saw blade and make a precise enough sled to get perfect miters? I really would hate to buy a tool that’s setup for failure.

I would think the miter saw should be just about perfect for this. If the one you have is really out of whack you might think of getting a newer one rather than spring for a table saw, unless you have enough other use for it as well as the space.

Here’s my new thought:

There are 2 things that control how accurate my miter saw cuts are.
a) the angle of the blade relative to the fence
b) the straightness of the edge of the board on the fence

I just (today) took delivery of a nice miter square. It’s heavy stainless steel with a 45° edge that promises to be accurate to 0.2mm per 100mm. It’s nice and heavy with sharp edges. One can’t help bit feel precise when holding it. I’m going to use it to take care of a)... the fence/blade angle.

In order to take care of b)... the presumably not straight board edge, I’m going to run it through the router table with the fence off-set 1/32” like a joiner. My fence has that function built in so it should yield accurate and repeatable results.

I think then I can keep the trued edge along the fence and everything should fit perfect. If they don’t, I’ll work on my sawdust & super glue filling technique.

Have your say...
