Extruder body progress

Idler bearing on its axle



3mm strut going through the hole for plastic with idler in place. Never mind the square section of the idler shaft .)


Here is the extuder body. Two pieces of ply wood are pushing on idler axis. The lessons to be learned here: never use band saw if you can use disk saw. All the pieces of plywood had their own geometry at the start. As work continues the errors only build up. Lesson 2: don't try to sand belt the errors if you can't ensure perpendiculars and parallels, and most times you can't.
