So More work on the bearings  theta and bottom parts are drilled and reamed to take the 4 pins . they are drilled and threaded 10 BA . they topper is then suspended above the lower part and held in position with the threaded rod . the assembly is then silver soldered and then parted and cleaned up . the standard is then drilled to take the bearing and all is looking good ...I now have to make the other one with the extra part for the vertical  gear bearing that is at right angles to the horizontal crank shaft...

Thats a wonderful result, very clever way to hold the upper and lower parts for soldering!

Agreed - brilliant solution

I learn so many great fabrication techniques from these posts. Thanks Willy!

Looks excellent and a technique to remember

Hi Everybody, thanks for the comments and I usually just make the parts with only a few pics ..so I will add quite a few more to show all of the process/!!!  So ..I have started on the other standard  and used sawing, chain drilling and filing techniques. I had to saw a piece of the 3/32nd brass from a larger sheet and I have put a large piece of angle iron in the vice  at an angle and clamped the metal To it and used a 24 tooth saw.... putting the metal at an angle allows the brass to be sawn with  more teeth in contact with the thin sheet. I use an 1/8" drill when chain drilling so there is a lot more room to angle the junior hacksaw around the curve . I also like to save as much metal as possible to use in other projects. I have used a 10" bastard file as this gives a much rougher surface for the silver solder to penetrate. I also make the tabs different widths so the attached parts can only go in the correct orientation .. I made this quick jig to bring the rods for the bearings to the same length , they are pre drilled and tapped eo I can remove them once filed to length...I have also tapered the tabs slightly toaid the fitting of the flanges ...

I have now attached the base plate and used some brass tapered pins , these are turned up on the small lathe and I have used a drill chuck as it has a hole all the way through . Also I like to use this chuck as I can open and close it with one hand using an extended chuck key. this means I can use the other hand to hold the turned rod .This is better than needing two hands to hold the two bars to open/close the larger chuck so the rod does not fall out into the swarf and get lost.?!! I have attached the base plate so I can rest the template on it to accurately file the part to the correct shape...the chucks are also colour coded as the chuck keys are different sizes

I have installed one of the standards and this is how I saw the plate , it means the saw is kept horizontal so both hands move in a horizontal plane ...

More great progress.

Hi all just had a weak week off ..managed to put my back out after asthmatic coughing bout !!  I have now been making the other standard and this will have the extra vertical bearing attached ..I have also made a new video with the first bering in place.I have yet to mill the keyways to join everything up and there is still the pump to make

Sorry to hear about the coughing fit, but everything else is coming along great!

Oww!! You've been having a rough time of it lately. Glad you're feeling better now and getting more great work done!

[crueby]

Hope you feel better soon, the stands are looking great!

Hi Thanks  Ron & Chris

Hi Willy, glad you are back on your feet. A sore back is never fun.

Interesting gear arrangement.  Normally I would have expected the turbine to be the higher speed machine which would be geared down to drive a much slower reciprocating compressor.  It would be interesting to know more about the operating speeds back when they were in operation.

The excellent work on the standards continues.  You haven’t lost your touch with those files.  Very ingenious fabrications.
