Great job Andy :thumbup: Keep up the good work brother. It looks like you are getting close have you figured out what's next when it is done?
I'm actually making plans for a 12 guage Gatling gun. :lol: I think that will be easier than this.
At least it will be a design of my own, and not trying to copy something. But that is years away for sure.

Andy you say years but I have a feeling we will be seeing pictures on it in about 8 months and I know you already have sketches and are making plans for it lol so say what you want but you are like me brother you don't sit idle :tongue:

Worked on the elevation linkages, knob, and fire plunger. My blueprints are incomplete, so I'm not sure what angle this is supposed to be mounted. Best I can do is guess by looking at photos. I may be a little high. Opinions from those who know?

It has been a while since I worked on the build, much less post any updates.
During this past fall, the shop I was storing it in was damaged during the hurricanes, and it got wet. Now it has rust. I began to feel bad about not working on it, so I decided to do something "simple" to get the ball rolling again.

I decided I would make the two part cleaning rod. I ran across some free poles.....pine, but about the right size. So I set about making the threaded ends to join the two halves. The center section is threaded 1/2 NC. The other ends are 5/16NF to accept some 40mm brushes and mops that I found.

Since I had the rod made, I figured I needed the loop and clamp to hold them to the trail. I could not find the blueprints for those in my collection, so I had to go by photos, and measurements taken from a real gun. Many thanks to K. Winget.

The rings were simple. Not real hard or time consuming, so no pics pre-installation unless requested.
Here are the cleaning rod attachments and cleaning rods in place on the now rusty trails.

Well after a long Hiatus, I’ve begun work on my pseudo 37mm again. Covid restrictions have provided some much needed down time to do some personal projects.
I’ve completely remodeled the house, and rebuilt the engine in my ‘43 Willys MB.
Also been machining on the pseudo gun parts.
This was a 10.25 diameter piece of round stock. Had to cut it down.

I had to take a break from the breech ring.
Decided to make something small like the sight mount.

For those unfamiliar with the sight mount, notice the three bolts under the bottom.
The front bolt acts as a pivot point.
The rear bolt is an eccentric bolt that adjusts the windage.
The middle bolt locks it in place once the sights are set.
I went ahead and made those parts functional.

Sorry to hear about the storm damage but it looks like you have made some major accomplishments to the project. With your skills it wont be long.

That 37mm is going to look awesome when finished. I think a lot of us would like to have one of those behind our WW2 vehichles!

Continuing with the build. Since I had the sight, I then needed the rest of the sight parts. Specifically the linkage between the left trunnion and the sight bracket, including another eccentric bolt and a turn buckle style adjustment on the linkage. Both used to adjust the elevation when setting the sights.

Here is the upper linkage with the roller bearings. The are bearings in the bottom too, I just didn’t post those pics.
turning the bearing caps was interesting.

My brother got me a double eye turn buckle adjustment of some kind from his work. In the center one end is threaded right hand and the other end left hand. When you turn the center it will either push or pull in opposite directions. It was perfect for the linkage adjustment. I just had to get creative with how I used it.
i had to cut the eyes off (seen in pic). I then turned and threaded the exterior of the stub to 9/16. Then threaded the inside of a piece of DOM to 9/16 and threaded the ends into the linkage. The set nuts were a part of the original assembly that my brother found.
Man that saved me a TON of of

Here is the full sight assembly. Once I got the geometry worked out, I milled key ways in both the trunnion shaft and the sight pivot shaft so that they wouldn’t move.
Much of the original sight parts were cast brass. Obviously mine are all steel, and I adapted what I had or could get easily to “look” the part and function.
The windage and elevation adjustments all work. I’m super proud of that.
By placing a level on both the sight bracket and the recoil sled I was able to confirm that the sight elevation mirrors the recoil sled when moved up and down
Very few who see this after completion and paint will understand the hours that went into this sight bracket and linkage.
Of course there is a lot of touch up welds and polishing before painting, but it passes the function test.

i totally understand! Nice work.

I have a home built 30mm GAU set up as a 37mm AT gun. My sight linkage isn’t calibrated but I can’t bring myself to put the hours into making it work. Great job on it.
