I’m using my current coping sled:



But the ¾” MDF I used as the base is too fricken high. In order to make the cut I need with my slot cutter the shaft of the bit is only about ½” in the collet. I know this is not the best thing for safety or accuracy. I can see that the cuts don’t come out as precise when the bit is used this way. So I’d like to make another version of this sled with a ¼” thick base. But with the strong force of the toggle clamps I need the material to be as stiff as possible. My 1st thought is this carbon fiber laminate I used to use on model airplanes:

It’s incredibly stiff and incredibly expensive!

Any other ideas would be appreciated as I don’t think standard ¼” ply is going to cut it!

THANKS!

Hi Nickbee

I take my lead from Bob R and Rick R. of the RWS and use 1/4" thick plastic....but I do put on sand paper so the parts don't slip around,, I have made many jigs this way and it works well..

I will say I think you use one two many hold downs, one will do the trick most of the time the sand paper trick helps alot...

One note about hold downs most use a cam action and it's not needed most of the time a simple block of wood with a knob will do the the trick in that way it will not deform the base.(cup/bend the base)

If you take a look at my gallery you will see many of them but not all ..

But this is just my 2 cents


below you will see the wood block type

BTW, look what's on sale at MLCS:

http://www.mclswoodworking.com/shops...sled_sale.html

Anyone have some feedback on these? The extra large sled looks sweet and simular to what I'm using now.

Nickbee

Or I can get a ¼” Phenolic plate and make this some kind of sled again…

I like the look of that sled more and more... And I take it the little "grove" that will cut into that base won't be an issue (see the pic of the current sled I'm using to see what I mean)....

Thanks BJ!

Hi Nickbee

If you mean the rabbit I don't think it would be a big deal,, just put it in the new one the same way..

At one time MLCS was giving a Free backup block ( the black one) ..if you buy one you may want to ask for it...it's item they sale for about 8.00 bucks if I recall free is free

"SPECIAL #1233
X-LARGE SLED & FREE EXTRA BLOCK"
