Re: Dremel mount

List,

What Peter excerpted here is from a private email I sent to Alan M
awhile back... It was an ascii 'drawing' to show how he (alan) could
mount a dremel to his Sherline.

Peter,

I did not know what kind of 'scrapbox' Alan had... So I was letting
him know that 1.00" stock would 'work', BUT that he would have to
screw the dremel into the adaptor BEFORE putting the adaptor ON the
mill (in place of the standard spindle). Because the dremel body is
oval, not round.

Your last question regards a 'snipped' part of my original message to
Alan. He wanted to drill and mill pc bds using the sherline. What I
am saying here is that the 'drawing' I sent will work fine for
DRILLING, but really should have a 'float' and nosecone to be used
for milling circuit traces on pc bds.

A "floating head" is one which can STILL MOVE (generally in one
direction) when it is in its' 'commanded' position. This is done so
that it can 'ride over any 'bumps' or uneven-ness in the material.
They(floating heads) are often seen in engraving machines.

The "nosecone" is a (generally) cone shaped metal or plastic "ring
surrounding the cutter. It is adjustable in relation to the cutter,
and serves to "limit" the cut depth. Combined with the float of the
head, it makes for accurate width engraving when using vee or tapered
cutters.

Hope this helps.

Yes.

Yes.
