PostSubject: Hudson steel Greasegun   Mon Apr 18, 2016 6:47 pm

Hudson steel greasegun, had this for some time and fettled with it for ages trying to get it to fire. Well not so much fire but load and eject as it fired fine but never more than 2 rounds, it would always jam or fail to blow back enough or the mag dropped slightly.
So what to do, well only one thing take it to 8ace as he always seems to be able to pinpoint the exact problem or problems and come up with a cure.
So greasegun left and a few weeks later as if by magic i have a working steel greasegun and i dont think there are that many around. It seems some adjustment in the trigger housing was needed as it had slight movement allowing the mag catch to move and the mag drop causing feeding problems. That s a problem i had no clue about i just thought worn mag release, now the mag locks firmly in to place.
Next the chamber needed recessing a little to allow the rounds to feed in smoother and that i think was that. Makes it sound simply but even the simple jobs on these can be a pain, so thanks 8ace for another great job.
Well you can see how it fires and its really good, 8ace thinks the rate of fire is a little slow but i am not so sure, the real greasegun had a low cyclic rate and i think the rate of this one sort of matches. The bolt is the original Hudson zinc but is old zinc and a hell of a lot tougher than new bolts, so as yet no damage to bolt head. I have found that you really need to have clean well lubed rounds or you get misfires, some caps were old so did just went pop no blowback, others the piston did not go fully up the round so again no full blowback, those were the only reasons it jammed or failed to fire when the round worked perfectly so did the gun, so its very round sensitive.
As for rounds the ones used were mullberryfield, you need a shaped bullet head to feed so MGC Thompson 45’s dont work. I will try c-tek and the CAW geasegun ones as i think i may have success with those and blowback might be better than mullberryfield.

That is awesome.
ROF seems very realistic. The real ones were designed to have a lower ROF.
In fact, one of my biggest issues with my CAW M3A1 is the ROF is too fast.............that and it is plastic!
I may try to weight my bolt sometime in order to slow it down some.

I like the CAW M3A1/1911 carts. They work well in my CAW M1A1, too.

A metal M3A1 with realistic ROF - just awesome.

Congratulations!

cheers

Cheers mate, its good to get it finally working as i have had it a while. Sounds a lot better than on the vid, no idea why but the video camera never seems to get the sound right. On Japanese vids the sound is great and i doubt the flash powder they use makes them sound that good, wish i knew their secret.

Superb Claymore  cheers I've been following the progress of modifications to your steel Grease Gun for some time with a lot of interest.
8ace has worked his magic again - as always - a lot of thought and effort has gone into getting this model back to life  Smile


ROF sounds as if it's on par with the real ones, or certainly very close  :-

If only Hudson and CAW's ABS / HWABS cycled as slowly as that !


From what I remember, the original Hudson Zinc bolt is a big heavy lump, significantly heavier than the later ABS & Zinc assembly. As you say, cartridges would need to be absolutely perfect to produce enough blowback pressure to shove that bolt back. Your steel model's looking and sounding great Claymore, congratulations mate!

It was my pleasure as it’s great to play with some odd/rare models without the cost of ownership  Very Happy

Yes it’s probably me as I thought the ROF was a bit sluggish, although I had just finished firing a CAW Tommy. But as you guys say looking at the online vids of real ones it’s probably spot on.
