crosscut sled construction

Hiya group;

I'm about to construct a crosscut sled for my table saw, for use in
constructing jewelry and keepsake boxes, and humidors. I want a
lightweight sled that I'll use to crosscut 4/4 or less by 48" boards
to precise length, and square.

The question I have is this: What's the best base to use? Is thicker
better? Is 1/4" baltic birch adequate? Use 1/2 " baltic birch? Is
there any difference?

Thanks a heap,
-Zz

mine is 1/4" 2 sided melamine, with fence and runners from baltic birch
ply.

the fence is a box tube, with the face taller than the top to clamp
stuff to.

I would think the runner might almost be the most important part of a
crosscut sled. Slop in the miter slot is what kills a home made sled,
wouldn't you say.

Which is a good reason for building a sled with TWO runners that spans the saw
blade.

The 1/2" seems to be a nice compromise. The 1/4" would just
be too flexy in my opinion.

You will end up with several in time and they will all
serve a special purpose.

*One*-quarter?? Is that a typo?

I use 3/4, 13 ply birch, for base and both front and back "fences".

It allows me to tack battens in place for specific angle cuts.

And yes, it is a heavy beast, but it is also stable.

Have fun.

I'm on my 7th and favorite sled.

Originally I went with dual runner designed as I could not achieve slop-free
all-season performance with maple runners in a single-runner design.

Once I ponied up for a manufactured runner with adjustments, I could get the
desired accuracy from a single-runner design. Once in a while I use a 48"
wide dual-runner sled because I need the extra support, but now I use my
22Wx18D single-runner 98% of the time.

IME, thickness is not that big of an issue, but quality (e.g., flatness) is.
My favorite sled has 5-ply 1/4" (full .25") base. I find that perfectly
adequate for a mid/small sled. I would go thicker for a bigger design.

Regards,

Steve
