I had a few hours yesterday to try out an idea I had. A while back I made a bent wood laminated guitar stand. I am very pleased with it other than I did not have a way to finish the laminates to a consistance thickness. After glue up I could see little spaces between the laminations. My method was to use a palm sander to smooth out the band saw marks. Idealy a thickness drum sander would have been the ticket.
The vacuum sled is 1/2” plywood nested in dados. I sized it to a piece of scrap I had. Its 6” wide x 3” high x 33” long. I drilled 1/8” through holes on a 1” square pattern on the top of the sled. A hole accepts the Ridgid vaccum hose in the end. I waxed the bottom and taped off the holes not needed. I had some left over cherry from a recent project that was about 3/16” thick. The stock sucked right down on the sled and passed through the planer with no problems taking light cuts. About .015” a pass till the side was clean. Flip, make passes till the second side was clean the I took .005” a pass to see how thin I could finish. (I have a dial indicator on the back of the planer) I was able to get .035” thick when the tear out stated. At .055” thick there was just one little spot of tear out. The blades on my planer are factory original and about seven years old. I wonder what I could get with sharp blades. The thickness varies a few thousands over the length. The sled is currently not glued or fastened together so maybe thats where I’m getting that.
The process of running the stock with the sled is slow. Turn on the vac, turn on the planer, run the stock, stop the planer, stop the vac, disconnect the vac from the sled, carry the sled to the front, attatch the vac, turn on the vac, adjust the planer, turn on the planer run the stock through and repete. I’m thrusty now.
This was something I had to try. It only took me a hour to build. Is it the best way, probably not. In a pinch if you don’t have access to a thickness sander and there are not many pieces to run it could get you out of a jam.
