I had trouble getting the split 50-50. Normally I find this very important, yet the wider and narrow belts both work fine.The belt looks like the same I have (Synchroflex(R) timing belt)... Was I just not careful enough or did you do something specific to get the split right?B.t.w. Is your Jig a two or 3 part jig? I used the two parts and put the top part on rotated 180 degrees, but it looked like it wasn't designed. I probably forgot a part. I need to split some belt again in the next week, so please me me know :)
Erik,I got uneven belt widths too. I noticed after I was done that the metal bands in the belts are continuously wrapped and form a spiral that guides the blade while you split.. Take care to measure your two parts of belt after the first couple cm of split. If they are uneven it will get worse or better depending on which direction the metal thread is pushing your blade.
