Tuning Umarex M1A1 Thompson Repair

Looking good! I think you’ll know right away if the rate of fire has slowed down. If not enough so, next step I’d explore would be locating a slightly lighter spring.
Welcome the the league of tinkerers, this is the fun stuff! 😁
I have not found a way to access the spring yet. I take out all six(6) screws and three pins and nothing happens. It is a journey.
By the way, "born2fly", are you or have you been a pilot; I suppose once a pilot always a pilot? Just wondering.

I flew Cessnas and a Citabria years ago. Back then it was actually affordable. If I were a rich man I’d get a Grumman Widgeon
 
My life has been fortunate not for money but experience, flown in many planes and Jets (civilian and military) Mike My life long friend and his Archer. We are planning to get together between our schedules and the weather.... We play our game plaster-of-Paris tanks and our WWII MP40, M1A1 and M3 Grease gun, we go at it and yes we have rules.
Great fun, after Whisky (the good stuff) and Cigars also the good ones. A couple of years ago I was heavier then.
Mikes Archer going to a Fly in with WWII Warbirds.
Buy the way I am on the left (wearing a replica of WWII Field Marshal Sir Harold Alexander, (Africa Core, British Army), Yes we dress up for battle.
Oh one more thing I ordered a chronograph so i can know what the RPM is and not guess.

Now THAT’s the life … good whiskey, cigars, and airplanes 👍. Well done! I’ve never had much PIC time in low wingers, maybe someday.
Most of my airgun stuff is just for target shooting. My mock battles are reserved for swords … both modern and historical fencing. “Weapons for two and breakfast for one”, as they say 😁

Ha ha ha (me laughing); we started with old Crossman pump air guns (after collage) and moved eventually to plaster of Paris tanks. It is so much actually destroying the tanks. It all started in collage in dorm rooms playing "Panzer Blitz' the board game. AND THEN UMAREX CAME OUT WITH AUTO WWII replica BB gun weapons. I should send you a few plaster tanks so you can feel the thrill. (They are painted... Look at the posted pictures Look at post #125 to see a few, I have 17 different models (targets) tanks and half tracks.
Anyway when the child dies inside of you than you are truly dead. I used to do fencing with sabers, saber foils, not swords I got pretty good.

Anyway I think I figured out to use a "felt" buffer pad to slow the action, they say (Amazon) will arrive tomorrow including the chronograph, I figure if I use the white metal and the doughnut it might work. Anything below 900 RPM is a win.

When my friend Mike fly's me to his house I will take some pics and movies

Those tanks do look pretty realistic. Good job! I built heaps of models as a kid, first the plastic kits and later the gas engine stuff. Had a lot of fun with all that. When I got a Dremel tool one Christmas I thought I had died and gone to Heaven ... it opened up a whole new world of possibilities. I've been a machine tool junkie ever since. And these days I'll use any excuse to chuck airgun parts onto the mill or lathe :)
I still routinely fence foil and epee during the week, but Saturdays are reserved for the stuff below. The rapiers have accompanying daggers which aren't shown. We call the sabers "Heavys" or "Heavy Russians" since they were made in Russia and are effectively real swords with rounded edges, not normal fencing sabers. In both cases we need to gear up with light kevlar/leather armor over our regular fencing gear. All this is normal HEMA competition stuff (Historical European Martial Arts).

I use Sabers with a saber foil.
If you want to see a bunch of tanks (plaster of Paris) get shot to heck check out on YouTube Mrdstony that was me shooting and see teste and an actual battel Mike and I had

Western Europe WWII Final​

A lot of tanks shot heck with edits and Music.

I like it. Fun stuff.
Do they have molds for the big Tiger tanks too?

They; you mean me.
I made the molds for 1/35 scale tanks, the masters for the tanks were made from my tank models that I put together, usually Tamaya kits. All tanks I cast and made are painted and I put the decals on.
The decals are made from scanned decals from the Kits and transferred to mailing labels.
Yes I made the molds for the Tiger and Panther. I have 17 different molds; I made them all.

Fun... you should try them for targets, remember they are only plaster, they explode with particular grace, just like the real ones. Vert much Fun.

Ahh, that’s right, you did say that you made the molds. That’s excellent work, I must say! I have never done much with plaster other than make a big mess. I’m guessing the treads are from the original kits and get re-used?

The plaster mold is taken from the original model tank tread. Yes, it can be messy, but a sheet of plastic and large syringes make it easy to inject the plaster, clean the excess and much less messy.
So Nope, they are also molded - this time from a re-enforced plaster mold using a large tube of Silicone rubber squeezed into the mold half and then put together, 30 min later the new tread.

That’s quite a process! I like those sorts ofprojects. I do have some casting experience, mostly sand casting automotive parts, but very little with the intricacies of models. I’m not sue my old eyes could capture all that fine detail.
