Hello up there,
I’d some problems a long time ago,but since a start using my dremel
tool in a drill press and those wax burs,sizing means nothing anymore
1.You just setup your drill press in the upright position with the
bur pointing downwards.
2.Drill a hole in your wax big enough to pass your cylindrical sized
wax bur.I have a small flat plate with a hole in to keep my wax from
maring on the drill press.
3.Position your dremel downwards to cover the full thickness of your
4.Start the dremel and hold the wax,since the vibrations of the
dremel will move your wax.
5.Then gently cut out the size by following the contours of your
drawing leaving a rim of approximately 1 mm.If you have to cut of lot
of wax,use a rough bur and don’t use a high speed (on my dremel I use
the # 1).
6.For the final and exact sizing switch over to a fine wax bur and
cut off the last mm.
With some experience you get this far that you don’t need to polish
the inside of your wax shank.A big help is …LIGHT. You could make
your own drill press with your flex shaft,but I use the dremel
because my wife bought it for me. have fun and I hope you get
there.Another solution might be this CAD/CAM designing machine but
you’ve got to have some small change to buy it.
