Video Of Mp44, Mp40, And Thompson M1

It looks to me like your bolt has been lightened. I see some grinding marks and a relief cut on the side that I haven't seen before. I have seen some M1 bolts that have the relief cut at the top like yours, but not on the side.
Whatever, the rate of fire is too fast for an M1. I'd be a little concerned about putting undo stress on your receiver. Order a bolt from IMA or some other source and I think you'll see the difference in a side-byside comparison.

Rsilvers, does yours jam a lot?

We played a game with him and trapped him in the car and then I ran with a 3 minute head start into the trails in the woods. I took many forks, and went down several paths to see if he could find me. When my friends released him from the car, he ran toward where I went so fast, that as he jumped over a white fence in which a guy was sitting on it, he crashed into the guy (must have scared him) -- I suppose it was a slightly more direct path than going around the guy. At full speed seemingly without having to stop and sniff the ground, he figured out what paths I had taken and found me in no time. The first time I hid from him in the house he did not find me, but the second time he realized it was a game and came right to me. I love playing tricks on him. Running around the kitchen island and having him chase me, and then suddenly changing direction and chasing him and them watching him slide all over the wood floor like Bambi on ice.

The Shep games must be universal. Even Shepherds born, trained, and shown in Eastern Europe instinctively know and play the same games when they come to the U.S. Does your Shep, when he is lying down, try to sleathily trip you/family with his muzzle when you step around him right at the last second?
Yah, he's the Photomosaics King.

He sleeps in the doorways or at the bottom of the stairs. There is no getting by him unnoticed. And he often sleeps against the front door, upside down, with his legs in the air leaning against the door. It is so funny looking. Needless to say, if the door was opened he would know it.

Robert, that last photo is really nice, with those white teeth at the ready! My brother has a nearly pure black hund (German Shepherd) which curls up on his lap when he is reading, or watching a movie. That also looks bizarre, as the dog must weigh nearly 100 pounds. I've got to get a photo of that sometime. :-) Regards, Walter

I have the same type bolt in my AO M1, I was told it is a "sand cut" bolt. 788 grams (27.8 oz)
I timed the gun today and it ran 1049 rpm mag after mag.
Jim will agree it's a speed demon, we took video if someone wanted to post it.
The 1928A1 timed at 962 rpm

Every single video of the XMG except those listed on the brp website show the gun jamming.
I wonder what type of ammo was being used in the videos I have seen...

This is certianly thought to be a cause of broken recievers - I refuse to get one for my gun. I do doubt your bolt is lightened, unless someone reduces the bolt mass and changes the spring rate accordingly, the gun wouldn't work anyway.
PK and others covered this before - you can't just a light bolt and go expect it to work - safely.
I cannot view the video (my work computer won't allow me ) but is the video being played back at real time or accelerated?
Anyone else have a pic of the Gunmachines bolt?

Can you weigh your bolt for me on a kitchen or postal scale? I need to know once and for all if my bolt is the correct mass. I already have a new spring on order, and will try other ammo. I hear Wolf is slowest firing.

Aren't you the guy who cleaned up at Devine's auction a couple of months ago? If so, have you tried out those new toys yet? I'm particularly interested in the Virginia State Police M1921 you acquired.

Once sorta revered as a Thompson God, he actually DID have some good ideas and good advice on TSMG's mixed in with a lot of fluff meant to sell his wares. Unfortunately he kinda got drummed outta' the Biz with his selling of the "Speed Bolt kits" and shit......'Course ya'll gota remember that when he started doing that, a nice 28A1 was selling for about a grand, at most, and a M1/M1A1 were selling (when you could actaully find someone who would WANT one) for about $400.00.....MAYBE.
"He's probably responsible for having more TSMG's repaired than anyone other single cause.".....that's what you'll always hear, but in truth the owner of the gun has the ultimate responsibility for knowing what is good or bad for his guns, Eh? ;-)

Thanks for the proper spelling. I guess his business name surpassed his own name. Considering the legacy of that company, an incorrect recollection of Klodzynski’s name might be fortuitous for the man. But when a guy advertises his wares with the slogan "WE MAKE THOMPSON‘S ROAR," I suppose the buyer is on notice that when they substitute a KLODZYNSKI part in their smg they will have in effect converted the firearm to operate outside of the specs it was designed for. These "Gunmachines" parts were developed not because there was a burning need to make Thompson's have a ROF of Ingram's, but because Klodzynski had a burning desire to derive income from altered, once vintage, parts. Many "entrepreneurs" try to manufacture a demand for an item that otherwise never existed. Klodzynski' just suffered the same fate as other shill men. I guess he wanted to be the Ron Popeil of Thompson's, but instead resembled the Einstein at Coke (circa 1984), who thought it would be a great idea to initiate an advertising blitz for "New" Coke.

Wow- this has been one wild weekend post- I am just now coming on board.
Weight of the M1 bolt assembly with actuator (total recoiling mass) is about 824 grams.
Phil is right; a heavy spring will do little to slow a bolt in the recoil direction, but will sure speed it up going home- I’d have a look at the spring.
Merle tells folks to lube with STP to slow their Tommy’s down, I bet using medium grease would do the trick too.
Some M1’s run fast and there may not be a problem, but it wouldn’t hurt to have a peek at her.
The photos of the bolt look absolutely normal- “speed bolts” have a definite “Swiss cheese” appearance.
Even after downloading the video to the hard drive, I could not get it to run real time. FWIW
