Sizing so far is not producing better results. Being able to measure the head without contact is important since the lead is difficult to measure without distorting. I only need to measure the head, not the skirt. I realize an air gauge will measure area and not diameter and that is fine. All I want...

Here is what I need to do. I need to measure the head size of soft lead air gun pellets. http://www.danbrownphotography.com/galleries/albums/userpics/_DPB7574.jpg My idea is make a die that will fit into my RCBS reloading press. I will then make a shell holder that I can sit the pellet on in a cente...

Thanks all. It does have the spindle. I have it listed for $300 and will take $200. If it doesn't sell I will take it on a trip to the scrap yard. Dan Its age and lack of threading capability make it less valuable as a general purpose lathe. Of course it has some value as an antique but antique lath...

My dad would like to liquidate his old F&S lathe. The ways are in good shape. It has a face plate, beat up 4 jaw chuck, steady rest. Could I get an idea of what to ask on craigs list? Should I expect the going scrap rate? Thanks, Dan http://www.danbrownphotography.com/galleries/albums/userpics/C...

Thanks for the help everyone. This is for a hammer in an air rifle. I've made many and used abs plastic. I just made one for a new rifle model. The surface area of the brake is much reduced and I think it will work better if I could find a stickier material. I can change the geometry of the parts to...

Howdy all. I'm looking for a table that lists the coefficient of friction of numerous plastics. I'm designing a part that slides in an anodized aluminum bore. It has a plastic brake that expands in the bore slowing the part's rebound off a spring. The plastic would need good wear resistance as well ...

Any ideas where I may find a follow rest for this lathe?
Thanks,
Dan

I'm interested in buying 10 barrels to start. 1:36" twist, taper lapped to my bore a groove dimensions. It seems some makers can't twist slow enough or can't taper lap such a small bore. Dan Shilen Bartlein Lilja Benchmark Brux Rock Creek Pac-Nor Lothar Kreiger Douglas Feddersen Spencer Green M...

Howdy all. I've been in search of a barrel maker that will undertake a .177 barrel project of mine. I'm not having any luck. Here is a list of the makers that I've tried so far.

Let me rephrase the question, what is the typical collet run out?
Thanks,
Dan

Howdy all. I just set up my old Jet lathe to accept 5c collets. The best I can do is about .0006" run out. Is this an acceptable amount or should I look for a higher quality adapter?
Thanks,
Dan
