Bevel Crosscut Sled

[terse plume]

I'm planning on making some waterfall bevel joints for a couple upcoming projects, and need a crosscut sled to handle the bevel cuts. The only purpose of this sled will be bevel cuts.

The pieces will be very long before making the bevel cuts, so unless I make the sled like 5-6 feet wide, I think I'm going to need some secondary support (probably just a piece of ply or melamine the same thickness as the sled, placed near the edge of the table). Because of that, I'm wondering if it would make sense to just make a fairly narrow sled with plenty of depth capacity, so it's easier to store and uses less material, something like 15" wide x 30" deep.

Has anyone tried a sled like this, or know of any downsides to this strategy?

Before you make the sled - do you have a router table?

I would generally recommend using a router bit of the bevel you desire than the table saw.

I don't, unfortunately. Also this is gonna be pretty thick material, 6/4ish

[dull drift]

There are 1 1/8" chamfer bits, but I hear you.

I think the tricky part with anything this big is that even if you make the sled the right size, it's going to be hard to move everything around smoothly.

at those sizes my first intention is bringing the tool to the piece - like a tracksaw or if you are really careful with guides and what not, a circular saw

Yea track saw would probably be best. It's on the shopping list behind router table 😅

That does make me think I should add some tracks for hold down clamps on the sled though, one less thing to worry about when cutting

[dull drift]

Yeah, defintiely

Just gonna... drop this here -

That would still be my go-to. Clamp a straight edge to the board and use a router

It's almost foolproof. All you have to worry about is the straight edge being perpendicular. There won't be any mismatched angles, no blade drift, nothing.
