Stack cutting?

[tvman44]

I have been cutting some oven shelf pulls today using 1/2" Poplar and want to try stack cutting at least 2 at a time which would be 1" thick or 1 1/2" if I tried 3. I would only try 2 at first. I have read about gluing tooth picks in the waste areas to hold together and my question is do I still use the same blade or would I want a more aggressive blade? Today I was using a FD TC#5 which is 13 TPI with a reverse tooth every 3rd tooth.

I don't find it necessary to use toothpicks, however that will work. I'd just tape the 2-3 pieces together. I'd move up to a #5 or #7 ultra reverse blade. Try the number 5 first it should work just fine.

If the pattern is not very intricate maybe use a # 7. A #5 could do it but you need good tension on the blade, the blade should not move sideways more than 1/8". Have good speed but very low feed rate. Let the blade do the cutting they say.
I always staple it together,

The other Mike, you just was ahead of me. Thanks
Poplar is soft as far as I know it.

Personally, I would not stack cut two layers of 1/2" hardwood. I think it would be too thick to save any time by stack cutting. However if you wanted to try it, I would go with a FD UR# 7 or 9.

I limit my stacks to 3/4" as I have found that any thicker slows you down enough that there is no time saved. I do limit my stacks of 1/8 material to 4 as I found that to be the most efficient.

I've done stacks that thick with woods much harder than poplar, so I think you'll be fine with a stack of two. Probably even three if you're careful. I second the FD UR# 7 recommendation. #9 if you're going to try three.
