With lots of help from board members on the forum I have finally started working on my gun and hope to shoot it in June. I would like to share with the board my progress both to pass on some knowlege and for the members to critique and advise me on using a 37mm antitank gun. This is not a guide, it is for my future referance only and to gain more info from this forum.
I tried to fill the recoil mechanism according to the FM 23-70 Basic Field Manual 37-MM Gun, Antitank, M3 page 26. I used a $10 oil gun, and ISO 32 Light Hydraulic oil and a plastic fitting(3/8 ID by 1/4MIP) to screw into the fill port of the gun. I do not know the threads size of the plug I took out but it is not 1/4 NPT, it was close so I used a plastic fitting so I would not ruin the threads on the gun. It seemed to work, although it was a messy job, I did manage to get oil into the gun with pressure and the barrel elevated as per the manual.

Re: Maintenance and Exercising my 37mm M3 Antitank Gun
Pulled back on the barrel 10 inches and tested the recoil, seems OK, maybe a little fast at the end but that may be normal? See Video. If the link does not work let me know, this is the first time I have posted a video. Is there a way to post directly to the forum? I could not find anything using search.

"Large Bore" I was Artillery in the Army and spent my time on the 155mm M198 and M109 howitzers. The 105mm seems small to me. Having said that, I really like the smaller size of the M3 37mm.Kevin Lockwood wrote:Thanks for starting this thread. I am new to large bore guns myself and will be following in your footsteps.
