My 47 year old Rockwell 10x24 lathe has come down with a virus and I am hoping someone will have some ideas. It runs great in reverse but not at all in forward. It has a 24 volt control system and the solenoid is not operating when in forward orientation. I have checked the barrel type switch...

For the ignorant, I would think that metals and sizes would play a part in press-fitting one metal into another but my question is, how does one determine what the dimensions should be? As an example, .500 male brass into .500 steel, should the male be .500 or .5005 or what? Thanks for your...

Threading is not one of my favorite things to do in the shop. I made a tap holder as Joe P. posted and it worked very well, with one exception. No matter which tap I needed for the job, the tap follower was always configured incorrectly (pointed vs crown). So I came up with this idea so no...

Getting ready to open the bore in the PMR #3 cylinder and being ignorant on these matters, is it best to ream the bore or bore it? My mill does not have a power Z-axis.

Does anyone know what the MT of an old Rockwell 10" lathe is? I have the manual but cannot find the info in it.

My first venture into model machining and I have an issue. What am I missing with the figures for this item?

In a cast brass cylinder, should one use brass or steel for the valve? Is one better than the other? I have a PMR #3 that I have started on and since this model engine building is new to me I like to make a prototype with on-hand materials. I just made a valve from some old 3911 steel but not...

Please forgive me if this is not the appropriate group for this question. I have a 3-axis rotary table that I plan on listing on Craig’s list or possibly eBay but have no clue what price I should place on it. I would be most grateful if someone would opine as to a fair value of this tool. It is...

Thirty to forty some odd years ago when I was doing some basic gunsmithing it became obvious that I could not afford the number of 6-48 taps that I was going through. Someone had posted pictures of this unit that looked to me as it would be of great benefit to me, and that proved to be so. I...

Hello everyone, I am looking for an idea for mounting the Z-axis scale of a DRO on an old Grizzly (g1008) small knee mill. The X and Y were not a problem and I have the Z mounted, just not fond of how it is mounted. I'm wondering if it may be better to go back to the dial indicators that I have...

Hello to all, I have been reading and looking since coming across this site by accident and have become fascinated with the model engines and the work folks do with them. I would like to try my hand at building one of these and needless to say, I am a rank beginner. After looking at many...
