Workholding - 19mm Wheel Blanks

[Wongster]

Guys, thanks for your input.

DaveH, hello hello! Been awhile huh? A friend suggested that to me too. One other way I thought of is to drill and tap a few holes along the outsider edge of the fixture and use the head of the screw to hold the part down, gripping the edge. I was hoping to do the same as what the Thai did. I'll be able to make a set of 4 at one go. If I can't figure that out, I'll still stick to one wheel at a time.

PixMan, I use 1/5 of the feedrate given in BobCadCam thinking that it is a safe figure to use. I'll try 100mm/min as I've only 1 such cutter. After inspecting the failed wheel, I may be going for 2mm cutter as the 0.5mm radius isn't very good looking... I know very little about the emergency collet. Read up a little and wonder if one can be used with my ER32 collet block. Some sites gave the name pot chuck.

dallen, I've not use shellac before. Can the part be removed from it easily and yet provide enough hold?

Guys, pardon me for my ignorance. I'll try to read up as much as I can.
