FWIW, a 36 inch circle is 1,017.876 square inches. 100lbs/1,017.876 = about 1/10th of a pound/sq inch - not 10lbs/sq inch.
this is why I read these threads
You are right, I did my math backwards whoops
I’ve personally flattened over a dozen slabs in the last year on the multicam, if it’s too cupped to stay down screw it down onto a piece of plywood and the vacuum will hold down the plywood. Any method for securing it while using a router sled can be accomplished better on the Multicam.
And weight alone is NOT enough to keep it still. I’ve had the Multicam move a slab well over 100 lbs.
I mean, that’s good advice, but still has the issue of my not being cleared on the MultiCAM
there us a class on the 20th
already signed up, but what about those who aren’t cleared, or who don’t have access to a MultiCAM
If they have access to the space they can get cleared on the multicam.
I hope you can see the other side of the argument here. There’s a finite amount of space in woodshop. The jig you’re trying to build and store is both easily built as needed (like what Mike did) and not actually the best way to flatten a slab (since we have the multicam). So the question is, should we use a portion of our finite space to store a jig that is both a) not the best tool for the job, b) easily able to be built as needed and I’d add c) who’s use will significantly impair other members ability to use the space, since it’s bound to be used in the general workshop and be very loud for long periods of time. And in that light I think it’s obvious why we don’t need it.
people might not have had the time or money to get cleared on the MultiCAM. I’ve been a member for 4 years, and am only just now getting cleared on it. People are only sometime available to help, but not always, so if you have any issues with the MultiCAM, you are stuck until someone can answer your question. Your other points involving storage and ease of assembly are valid though
