Maybe another lost post, anyways its been on my mind when I came upon, on Utube, a person using a
plain ole twist drill on a shaper. Gotta try that, I have endless supply on mutalated drills courtesy of
two boys. So I half way put one to the grinder no drill dimension just sharp- stuck in the shaper, you
can dial it in pretty good Its round. Ill tell ya the smoke and chips fly. Thoughts are for roughing
the rust instead of using up my HSS blanks. Just keep it choked up cause they will flex a little. Couple
cold ones and, what if > I stick one in the lathe. Just so, I left a 2" brass round still chucked up from
yesterday. Again setting my rake is easy its round, centered, need a little flat stock on the top so the
allens dont go in the flutes. Im am to face it. Oh my, what a job this is unbelievable. Lets turn a couple
inches, unreal the finish is beautiful. It puts out a continual snake on each pass that looks like a necklass.
The only downfall is, its for right turning. (right & left tools) I never aggreed on that, in shaper land,
left is left
right is right, anyways the opposite side on the drill has to be ground backwards for left turning. There
is no doubt its been done but this has never entered my mind. Im an HSS user and on line and mail
orders is a pain, remember to use the fattest drill you can get in there. Now I will try on another
lathe that will take a one inch drill in its toolpost. bottom line is, drill is HSS can be ground, cheap
always on hand- locally bought. I put this in general cause Its general info. I think. Ill be back I
cant wait to see what a one inch twist drill will do today. sam
 
Sorry I forgot to add that so far there is no mess, I turned about .50 and produced only long snakes.
No chips no shop vac. samuel


My sole reasoning is just to save on HSS blank stock, and a use for busted up twist drills.

I had to hunt up that video. http://www.youtube.com/watch?v=qbqOFkZjM-c is the long version, but it shows lots of views of his shaper. Interesting project. You can really hear the chatter with the bit extended so far out. Just think of the finish with it properly supported.
 
It's fine to use a twist drill as a shaper tool, after all it's high speed steel, but I don't understand the reasoning for using it like that. That annoying sound you hear is chatter from the drill flexing because it's not supported close enough to the cutting edge. Most of the helical flutes should be cut off and the drill held with minimal overhang. That will produce a much nicer finish without all the chatter.

The shaper is a home-built from his own castings, according to the notes with the video. Anyone know who he is? It would be nice to track down the story of the build. I think he made a comment on the video about pop cans.

It looks like a Gingery, but I don't think it's the one from http://www.chaski.org/homemachinist/viewtopic.php?f=14&t=86770
The table on this one isn't as ventilated.
