This a crosscut sled I made using some plywood and MDF offcuts to allow me to accurately cut small parts, primarily for boxes. The design incorporates ideas from various projects here on LJs but especially from Kiefer from whom I took the micro adjustment facility.
The sled measures 24×12 and is made from 1/2inch ply covered with stick on film for dry marker boards. I figured that this would be useful for note making along the way! The fence is MDF stained ebony and has a replaceable face. It will accommodate timber up to 7 inches wide – quite adequate for what I make. Kiefer very kindly gave me a diagram explaining his adjustment mechanism.
However, as my fence is made from 1/2inch material I thought it would not be strong enough to take the mechanism and therefor decided to use a drilled and tapped aluminium block that I attached to the fence for greater stability.
I fixed M6 (6mm / 1/4 in) threaded inserts to the base and made matching 8mm holes in the fence to allow for adjustment during the set up process. Cap screws ensure that fence is securely fixed to the base.
I used a 5-cut method for adjusting the base that I found on You Tube. https://www.youtube.com/watch?v=RZ_nzvYEZ-4
I made a stop block mechanism to ensure consistency on repeat cuts. A piece of hardwood was attached to a piece of aluminium angle that had been threaded to take a couple of cap screws. The stop block is fixed to a length of channeled tubing on top of the fence.
Nothing radically new here, but I think it will work for me.
