Rebuild time for my Upshur single

[ironman123]

Thanks Art.  I do have a cnc milling machine.    I just ordered the plans for the engine from Upshur Engine Works for $10.55     I figured that was easier than using all my brain power to try and remember who I loaned my other plans to.   I made my other cam using the Gene Switzer Cam Grinding Fixture I built many many moons ago.  I bought the SIC issues 39, 40, 41 to build it.  That is a long story.   I boxed it up and it is stored in my shop loft, I got into steam engines, rc boat building (mainly tugs and coastal fishing trawlers), then into wood turning (bowls mainly)  now I am back into machining and rebuilding some of my engines.

Ray,
The cam grinder sounds like a great idea. There was one in SIC but, I've not got to the point I think it's a necessity and made it. Good luck getting it going again.

I realize I haven't done anything here for a bit but, life has gotten in the way. Work has been the busiest in my memory. I have gone from four tens to five. This week we had a Covid 19 scare. I did get tested as well as the bosses. My test come back negative. The person we're most concerned about and was asked not to return for the safety of the rest of the employees will get his results Monday or later, same with the bosses.
I intended to spend time this holiday weekend working on the rod for the Upshur rebuild. So instead I'm ordering a new power supply for the cnc computer and hoping that is all that is wrong. Let you know as I do.

Glad to hear your test came back negative, Art. Hope the same positive outcome for the others involved. Having Covid-19 doesn't sound like a fun time!

Kim,
Thanks, I know it's no fun. I've lost two elderly friends to this point. Don't want to see any more.

The last guy in the shops covid test came back negative, that's great. I installed the new power supply in the computer and got on joy. I have my nephew looking for the motherboard to set the computer up properly. Hopefully this wont take long. I want to get back moving on this rod and engine rebuild.

     Hi everyone,
I had started this post before covid. After the lockdown I went to 50 hour weeks and remained on that schedule for 2 years, Slowly treading backwards until we finally got caught up. When I went back to 40 hour weeks I still didn't feel very ambitious for a while. On top of that, last November the computer on my mill died and had to be replaced.
I have though gotten something accomplished in that time. I decided I didn't like the design of the side covers. So I went ahead and made new ones with 4 mounting holes, and radius corners.
 

Here are two covers the good one has a gasket & the bad has blue sharpy marking it. Alongside them are the appropriate tools to push in the crank and cam bearings.



This photo shows the completed covers, one installed the other sitting next to it. I've begun to make some progress and will post more later.

Looks great!
That was the highest rpm Upshur that I have ever seen!
Hope the rebuild goes well.
