Re: opertunity to have uWaveEngineer1968 test his gear hobber - 8640B for $1
initial setup takes about 45-60minutes you are right on that, this is a one time operation, then put a stack of blanks on and hob them, change the stack and hob the next batch, the time to change the

Actually, making an EDM attachment for a milling machine is really quite easy. Some years ago, I wanted to get into the guts of a microwave oven to modify it for other uses and it was buttoned up

You are, of course right, but letting the experts do their thing will quickly put the gears out of reach of everyone that truly needs them. People that can afford the experts, don't need

i remember years and years ago we had a similar problem with another plastic part, we used a part sprayed graphite on it and then plated over a layer of copper, this served as a EDM tool, problem was

You can't do a decent job of cutting a bevel gear on a mill. To quote Machinery's Handbook: "Cutting Bevel Gear Teeth - A correctly formed bevel gear tooth has the same sectional shape throughout

Re: 419A Chopper Replacement
Well, here I am answering my own question(s). This one was sort of my fault. To wit: When I got this unit, I tried to turn it on, no luck. Seeing the battery charge pushbuttons, I feared the worst

Hi Lothar, The electrode could be something as fancy as a CNC made graphite model, or it could be something as simple as adding a little plating to the original plastic gear. There is no intrinsic

54120A/B interface cable tip
Hello everybody: It seems that the interface cable for a 54120A/B system is very simple to clone. All connections are straight thru and it can be built in about an hour. You can get all the parts from

still trying to figure out where you get the hour for hobbing the gear from ! those are small parts with fairly large DP in soft material, according to some preliminary calculations based on delrin
