I use the segmented belts on both metal lathes, the wood lathe and the milling machine. The belts on the milling machine are a particular bugger to replace — there are three of them driving the main spindle and access appears to have been given no consideration by the designers. Switching to...

Corinth, far up in the northeast corner of the state. Like you, there doesn’t seem like there’s anyone close by.

When I was a HS freshman, making these was one our first shop assignments. They are not complicated.

My heat treatment oven is a discarded dental ceramic oven. I came by mine by being a dentist, and this one was discarded because someone (not me, before my time) used it to melt silver for casting some none dental, after hours thing. Silver contaminates the oven muffle and when it is then...

I installed a 3-axis DRO from Toauto on my mill and a 2-axis on the Enco lathe a couple weeks ago. Still have not looked at the manual ( if it’s anything like the manual that came the VFD’s I have on my three lathes it probably is not worth the effort). Instead, I went to YouTube to see how to...

I not going to be much help here, animal12. The manual certainly isn’t, as you can see from these photos. Not a word on the lubrication chart (or elsewhere in the manual) about oil to be used. I bought a supply of ‘spindle oil’ and way oil a number of years ago; the labels came loose so I...

I knew Dr. Biggers as well, but from the professional side.

The larger of the blue boxes houses the trip release for the screw cutting auto-stop. George H. Thomas described the mechanism in Model Engineer and I have made it for both my lathes. The setup on the Logan lathe follows the Thomas design almost exactly, but the presence of the gear box on the...

As you can see, I have made a number of modifications so it no longer looks as it did originally, but the basic form of the lathe is still there.

I have the manual but it’s a little strange. All the apron controls are shown reversed right to left. Same controls, just backwards.

Corinth, up in the far northeast corner of the state.

Here is the information on the plans for the Bolton triple in Model Engineer, the title of the series and issue date of the beginning of the series.

I was born and grew up in Spokane, and lived here until moving to Southern California to go to dental school. My sister, brother and I are here now at my Mom’s bedside. She is 94, only a couple months short of 95, and she went into kidneys failure Wednesday. We got here as soon as we could...

I’m not positive, but I think the Ozoff Wall Engine is also from plans printed in Model Engineer. Could be from Live Steam or Home Shop Machinist though, as I was getting all three magazines at the time of that build.

There was a series on building the Bolton triple in Model Engineer in late 70’s, early ‘80’s, I think. It was on building the engine with some modifications, I cannot recall the title of the series. I am in Spokane, Washington right now and cannot check my stuff for the actual series title and...

The Bolton triple.

my son still has that engine, the others have drifted away to other homes and I haven’t kept up with them. In progress now is a triple expansion of familiar form, being built without castings. I’m trying to do better about recording progress. This was taken last fall and I do have more...

Yes, but with a lot of time in between. I have not been a good photographer of my efforts over the years and little to show. This is an engine I made for my son when he was about eleven. He’s forty-two now and the engine has aged as well.

I’m about two years late with this. I’ve responded to a few posts since joining but mostly I have been just reading and enjoying the photos of all the marvelous engines being made. I got my machinist training at the high school level (not the typical HS ‘shop’ but real training’) but never...

On more than one occasion I have managed to ‘lose’ the micrometer without taking one step away from the lathe.
