A friend of mine asked me if I could make him a live edge table. Unfortunately the maple slabs were twisted and needed to be flattened. I built this flattening table and used my router in a sled. Several passes took the twist out. 5 large garbage bags took care of the wood chips taken from 3 slabs. Made with 3/4 and 1/2 inch plywood. 5’6”L-2’W-4”T.
Looks great! Few questions... Is the white material for chip control? What router bit did you use? What is the black metal on the rails (like how that would give smooth movement and give longevity to the sides)?
Thank you……the white material is for chip control however I didn’t mention it because there are wood chips everywhere 😃. Thought someone would comment lol. I used a CMT 1/2” shank 1 1/2 diameter bit. This was the safest one to use in my porter cable router. The others they had were for a CMC machine and were a metric size shank and could spin in the collar. The black metal is a 2”x1” tubing I found and it works great to slide the router box along. I would suggest getting some “slip it” or something similar from lee valley and use it in the router trough to help slide the router back and forth. I use slip it on my table saw, jointer and thickness planer to help the wood slide on the surface. It is an excellent product and won’t stain the wood for finishings. Just rub it on the surface and wipe off.
Rodrick, very nice design and execution, great looking sled. I too made one of these some time ago, real handy when working with twisted, cupped, and bowed lumber, saves time and effort over hand flattening. As for "……the white material is for chip control", forget it, these things find places to throw chips you didn't even know existed. I made mine to fit my work bench width and use the bench as the bottom of the assembly, much smaller jig and easier to store in my small shop. After flattening one side, I run the board through my planner to get the second side. The volume of chips then doubles, makes for quite a mess. Nice work on your flattening jig, enjoy.
Thanks Oldtool. The only thing it did help with was preventing the wood chips from flying across the room 😃. I have seen some with a brush on the bottom of the sled much like a CNC machine. Maybe I’ll keep my eye out for that. Thanks for the compliment!
