The Home Machinist!

Easy as pie. Think "4 jaw chuck".

The NorthStar Master Carver is a commercial made unit designed for the furniture industry. It is a very robust and accurate machine for continuous use in making furniture parts. Sadly it is no longer manufactured. The new cost was around $15,000. I "stole" this one for $1,200: It was owned...

A couple photos below. I have tons of photos and a word document describing how it works. I will put it up if requested. This thing weights around 2000 pounds and is very accurate. http://i736.photobucket.com/albums/xx5/Altamaha/Duplicator%20Nov%2010%20003.jpg https://im1.shutterfly.com/media/47a5dc...

I do it this way. I will post more photos if requested.

This one loves Mark V Weatherby actions:

Many, many years ago I was in the machine shop of a large industrial complex. The unit was down in labor strike and salaried folks from facilities all over the US were runing the place. As I was a bootstrap engineer (worked in machine shops and learned how to make chips before I went to Engineering ...

Heat treat first, then grind. If you have a lathe, a tool post grinder is easy to make. I will post a photo of mine if needed. Reamers have to be ground after heat treat, they warp and change dimensions when heat treated. And you cannot get the cutting edge reliefs in without a tool post grinder. Pr...
