After several attempts myself trying to rig something that might work
I've decided I need part of it made by someone more capable.
The basic component I need is a hard steel rod 1/2 to 3/4 in thickness
maybe 18 inches long. One end of the rod needs to be milled with a #2
Morse Taper. The other end needs to be drilled and taped to accept
threaded fittings probably 1/4-3/8ths but any common thread will do.
I can get parts from MSC but assembling the rod from parts will not be
as cheep or as strong as making the entire rod from one piece.
The #2MT needs to be accuratly centered so there is no wabble in the rod
when my lathe is turning.
Can anyone recommend someone local to Denver or not that can make this?
hanging 18" off of a morse taper is asking for problems. unless you
hold it with a draw bar you're likely to see it go flying... a long
skinny rod on the lathe runs the risk of getting whippy once you apply
forces to it while turning, even the off center forces of mounting a
turning blank and spinning it up, and 1/2" is probably too small to get
a full mt2 on anyway. I sure hope the tailstock has a center in it
supporting that end.
consider getting a set of morse taper collets and doing your headstock
work holding that way.
you can ask in the metalworking group- rec.crafts.metalworking, or
something close to that- where you'll get tons of advice, perhaps a
local to you connection or two and probably a political rant or two.
the yellow pages is also a good way to find a machinist.
what are you making, anyway?
Your are better off chucking the rod into a 3 or 4 jaw chuck. MT is not
hard to make but needs to be hardened after cutting the taper. 18" of 3/4"
steel rod secured only by the taper is asking for trouble.
I'll take that into consideration if I can ever find a shop that can
MSC has the parts I need but a solid rod will be stronger. I've also
heard from someone that has made one that a chuck does not work very well
Easy enough to find someone to make it. Look in your phone book for a
machine shop. Be prepared. I don't know what the prices are in Denver but I
doubt they are much different than here. I'm thinking $250.00, maybe more,
depending on details.
it used to be available but not any more
I can get the parts to make two from MSC for $100 (2 because the rods I
priced come in 3 foot sections). It would essentially be a #2MT endmill
holder and a steel rod. I can probably do the drill and tap of the end
myself but I need to get the equipment to do it.
