Re: 37mm anti tank gun build....non-DD
Making me jealous. This looks great!
I was toying around with the idea of mocking up a fieldpiece out of old pipe and a trailer axle I have laying around the shop, painting it green and parking it in the field by my shop. After seeing this I think I would be embarrassed to even try.
Great job. I imagine even using A36 this is costing a small fortune.

Re: 37mm anti tank gun build....non-DD
It has been a while since I have been able to work on the 37mm. I have made a little progress. I have found a CHUNK O' STEEL to make the breech ring out of. That sucker is HEAVY! It is way too big for what I need, but I'll cut, then mill it down. It'll take a year, and untold numbers of cutters but I'll get it eventually. I also rounded up a piece for the breech block.
I have also been working on the traverse gear and the bottom of the carriage. I hope to have the upright "ears" welded on tomorrow.

Got the upper armor mocked up today. I got the carriage base and traverse gear finished. I got the trunnion ears welded in, and three of the armor support brackets. I have got some fine tuning to do, but I had to see the armor attached. Vice grips had to hold it long enough for the pics.

Re: 37mm anti tank gun build....non-DD
Progress have been slow, but progress is better than standing still or backing up.
I got the bottom plate of the carriage made, and the 6 threaded attachment points. It also got everything tuned up so that everything is free and clear during traversing. It was a pain in the rear, but I finally got it after taking it apart 10-15 times.
I also got the armor supports made, and the armor drilled and bolted up.
Next will be the traverse mechanism.....wish me luck!

Re: 37mm anti tank gun build....non-DD
I am also building one. I started with the Mac Replica idea and tried to make it a bit more realistic. Yours by the way is over the top fantastic. Where did you find the blueprints? I have been working from pictures etc. Thanks, Bob

There was a time Deutsche-Optik was servicing WW2 German binos and riflescopes. The M6 is rather simple, a lense array with etched recticle. No elevation or windage turrets should be a simple cleaning, mold removal and fresh hydrogen purge.

Re: 37mm anti tank gun build....non-DD
It has been a while....a loooong while since I posted anything concerning this build project. Honestly there has been little done. I did machine and build the recoil tube and buffer assembly, but I did not want to post pics of that yet. I did not want someone copying the design and then possibly using it for live fire and getting hurt. So I'll just leave it at that. Mine will look good I hope, and there'll be pics of the finished tube in place at some point.
I have started doing is working on the traverse and elevation mechanism. These have caused me much head and heart ache. I am definitely going to have to stray from the blue pints on these, as I do not have the machinery to manufacture such. I am working on two or three designs that should look "ok" but at the very least be sturdy and functional.
I know folks like to see the fabrication pics, so I hope to be able to post a finished part within the next week. However, today what I have to show are the programmed parts to be cut to make the Tool box and battery box that mounts to the armor.
I am going to cut them this afternoon and hopefully begin the fabrication process. My head tells me it will not take long, but past experience tells me I am going to hit several unforeseen bumps along the way.

Re: 37mm anti tank gun build....non-DD
Today I got the parts for the Tool/Battery box cut, and most of the box made.
Here are the parts cut and ready for cleaning and assembly.
I had to get creative when I was trying to figure out how to make the lid, which would have been stamped one piece. I obviously do not have the press or dies for mass production, so I designed the corners to be rolled and welded.
Here is the before welding pic.
After welding a polishing.
You know that you are a bit OCD when you make your own hinges from scratch.
Here are two pics of the tool box with lid and hinges. It is not exact. My bead roller will not run the corners like the original. So, a bead on each side and the latch end will have to do. It is just sitting on the armor support for looks. I had all I could stand of it today. More tomorrow maybe.

Re: 37mm anti tank gun build....non-DD
Years ago I built a 450 horsepower supercharged alcohol injected funnybike from the frame up. I fabricated everything, and even did most of the engine machining.
That being said.......................................
This project impresses the livin' tar right out of me!!!!!!!!!!!!!!!!

Re: 37mm anti tank gun build....non-DD
Very nice and detailed job. As for heat treating, since it won't actually be placed into service, nothing will be needed to be hard, but if you wanted to, low carbon steel can be case hardened with Kasenite; it is very easy.
As for your recoil mech; please post pics. You are not responsible for what someone else does with them.
I would make it a black powder cannon; next you should build a rifling machine for it. A piece of DOM tubing will work for the tube. 1.5 ID, and 5 inches OD at the breech; I measured a friend's real one last week.
If you need any castings, there is a place here that will cast anything in bronze or aluminum.
