Cutting #8-32 threaded rods
Hello, I want to cut meter long sections of zinc plated steel #8-32 threaded rods into 2 inch sections and chamfer one of the two ends of the 2 inch sections. I’ve tried a few ways and a vise with some duct tape on the mouths holding the rod still under a fine toothed metal hacksaw seems be the...- fmenard123

Slow-turning lathe+Mill for patterning a helicoidal groove around a cylinder
Four axis mill, rather than a CNC. A Bantam cnc with the 4th axis appears to be the best bang for the buck.- fmenard123

Slow-turning lathe+Mill for patterning a helicoidal groove around a cylinder
Agreed - the right terminology is ‘helical milling’. I have researched this for several hours and have found this video on YouTube which explains it best: So the milling table which moves left or right via a rotational screw is converted to drive a dividing head through bevel gears and...- fmenard123

Slow-turning lathe+Mill for patterning a helicoidal groove around a cylinder
Hello, I need to make a one turn every 2 inches, quarter-inch wide and deep, groove around a ‘bolt’ that has a half inch diameter. I am anticipating a fixed mill with a stage holding a linear rod, which is moved forward slowly and which completes a full revolution at half the speed as it is...- fmenard123

M5 threaded rod cut into 1 cm sections with one chamfered end
Folks, your excellent answers had me converge on nylon set screws that have flat screwdriver heads and not hex holes. Essentra sells 1 cm long 50M050080R010 for under a penny each, which is 30x cheaper than metal.- fmenard123

M5 threaded rod cut into 1 cm sections with one chamfered end
Ok, wow, did not expect so many good answers… so here is more explanation… I have a fiberglass pulling stick with a 4.5 mm diameter, which is terminated on one end as male M5 and on the other end as female M5, the purpose of which is to attach several sections of such pulling sticks together to...- fmenard123

M5 threaded rod cut into 1 cm sections with one chamfered end
Hello, I am attempting to figure out how one would go about manufacturing thousands of 1 cm pieces of M5 threaded rods. The need is as follows: rather than having an M5 threaded inset, moulded or hot pushed into it, I would mould around a 'male' ended, threaded rod, or screw in that 1 cm piece...- fmenard123
