I need to make a lot of these slots and the 1/8” ply pieces are as small as 2” x 2” with 4 slots. I’ve had to make two passes with my my 5/32 router bit. I asked the local Carbide Sharpening Co. if they could grind down a 3/8 bit and they said the bit wouldn’t perform well as the chips wouldn’t escape properly. They’d have to grind additional relief and don’t have the equipment to do that.
I could do it with a table saw blade but I can’t find anything with a kerf that big. I suppose I could grind down a 1/4” dado blade to .160. Anybody ever do this? Any foreseeable problems?
I’m also considering setting up a gang slot cutter with a 1/2” shaft maybe 2’ long running through some pillow blocks. I could space out cutters at 2” intervals and cut lots of slots at a time. However, slot cutters are designed to run at 11000 rpm and I’m not sure if the bearings would handle those speeds.
