I'm collecting tooling for my Unimats
i didn't see a flycutter made by Emco, so i decided to make one from the pile of scrap stainless i have accumulated.
the tool was produced from a 1.5" diameter scrap 416 stainless steel meat saw shaft
after turning the 1.5" diameter to 30mm, i drilled and tapped for M12-1.0 on one end, as the flycutter will be threaded onto the unimat spindle.
next, the 10° angle was cut into the top of the cutter and the slot for the 1/4" tool blank
i cross drilled a 4mm hole for use of a tommy bar to tighten the flycutter to the spindle
the flat was made for the retention screws , then drilled and tapped to #10-24 tpi
i broke the 10-24 tap on the second hole, that required an hour of backpedaling to resolve , but it was a favorable outcome!
i lapped and polished the tool for presentation as follows:
when i get the milling table in my hands, i'll make a video of the tool in operation
until then thanks for reading!
