Thinking of making a D bit type reamer for the crank bearing. Anyone make/use one? I'm going to use 1/4" drill rod.
Just looking for ideas as its way to cold to work in the shop today. Need some inside work...

I have gone through the entire drawing package checking for fasteners. If I am correct, all that is needed for assembly is 2-56 hex head bolts or screws, from 1/4" to 9/16" long. Am I correct? MicroFasteners has them for $12.40 /100 for 3/4" brassand $11.90/100 for 3/4" ss, shipped.

I got some time in the shop and got some of the .125 pins cut to length and the spacers cut to length and tapped. I still need to cut the contour on them. I hope to get more done in the next few days. I made the spacers from brass. I hope everyone is ok with that. I hate to tap small hole in steel. I was going to make them in aluminum but with the concern of the strength of the thread I went with the next best thing.


In the 3rd picture you can see the .125 Pins that still need to be drilled and tapped

Seeing all the progress you guys have been making has got me off my behind...

here are the valve chest packing glands


There is a dimension missing on the plans for the valve spindle, the last bit that rides in the top of the valve chest. I am going to assume .25", and will adjust if
needed after I make the 1st one, and let you all know.

Cheers, Joe

The pistons are .485 but the orings are made to fit .500 so the cylinders should be made to .500
Correct?

Just letting you guys know I'm not frozen solid up here (-23 C or -9 F tonight) and I am working on my parts. Starting with the eccentric. I'm just about set up for a small "production" run but will do that tomorrow when I'm more awake and less prone to errors...plus I have a question. The drawing says to use 2 set screws 90 degrees apart but does not list a size/ thread. Recommendations? Its a 0.5" collar that has the 1/4" crankshaft going through. Also, am I to supply the set screws?

I'll grab a picture of my setup and 1st parts tomorrow - batteries are dead tonight (to many family pics over Christmas...)

Mike
