small annoying vent

[Charlie Jones]

I am building a new sled for my sawstop and I built a pretty cool looking fence which is two 9 ply 3/4 maple ply laminated together and bordered with some poplar for a clean look. Well today is is slightly bowed, and even if I force it flat, there is no way in hell I am getting it square to the blade. I got it close, about 89.5 but that isn't cutting it. Oh well. I'll build a new fence out of hardwood. I have poplar and hickory sitting around that is spare or I dig into the nicer stuff. Hickory will just make the sled 10 tons.

Flat plywood is a thing of the past!!!

Just run the hardwood face through your jointer. Check it again after a couple of days.

yup - my hardwood (well, poplar - using it up from another project) is still flat after it was face jointed and my sled was used a ton today so it's all good

Now i have a dead flat (hope it stays that way) poplar fence. I took two flat poplar boards and face glue them. Once dried I re-milled it on the jointer and planner to make sure it was once again flat, and to the thickness I wanted. Well see if it stays.

I imagine you'll be OK. I have a couple of sleds with vertical grained fir fences that have been stable for many years. I have also used laminated 3/4" BB ply on a couple but I drum sand (read mill) the blanks after laminating and before cutting to final dimension. these have remained stable for years as well.
