I made fence system lock with angel 26 degree/64 degre, this is make easy smooth, stabil and strong, why i not use 45 degree, if i use 45 degree more hard for move and not durable ans strong like 26 degree. i combine that with toggle clamp and extra addtional look on back fence for make stabil and strong

this is really help me for working and I am very pleased with the results and would recommend making one yourself
