I just acquired a couple of Ball end mills, one is 1-1/4", the other is 1". I need the shanks reduced to 3/4". I use DCMT 32.52 inserts and want to know what carbide hardness to look for. The mills are tool steel and can be scored with a file
crowning
I have a lathe and have crowned barrels on it. In this case the barrels are already crowned and all I want to do is put a 11* bevel just slightly larger than the bore. If you guys think it should be done on a lathe let me know what speed and if I should use cutting oil
Thanks all for...
I just bought a 11* muzzle crowning tool with a brass pilot from Brownells. I tried crowning a 22rf barrel by hand using light pressure . The result wasn't smooth, it looked like a fine chatter. The pilot fits snugly in the bore. Should I use a lubricant ?
micro motion trigger
The creep can be adjusted by the sear engagement screw and the trigger movement after firing can be adjusted by the overtravel screw
I need opinions on this 5C collet chuck listed on Ebay auction 2716 6755 4173. Need opinions how how these type Collet holders compare to the Drawbar types. I don't intend to do production work
