Lewman Arms Grease Gun rebuild.

This is a parts kit reweld I did a while back but didn't post here. This is a little bit behind the scenes of the process. This was a post sample build for a rental range. Its the first one I've done and the fixturing took a while to figure out. Ended up turning out pretty good in the end.

I didn't think it was possible to re-assemble a receiver that was so extensively cut up. Awesome work.
I'm guessing you must have to spend a lot of time getting things lined up and fixed in place to hold tolerance? What would you say was the hardest part of this job?
Piner_phab@reddit (OP)
This is actually my day job. I build stuff like this all the time.
The most difficult part is, making sure everything is lined up before welding. That takes a lot of time, especially if you don't have a specific jig for a gun like this one. I ended up using an exhaust pipe spreader tool to hold the parts in place before tacking.

How do you stop it from warping all over the place when you fill gaps like that?
Piner_phab@reddit (OP)
Wish I had a simple answer for you, thats part of the challenge. Sometimes I get it right first try, sometimes its struggle. I sometimes have to cut it back apart and try again.

Might be a job for a cad-plated mandrel with a fluid cooling loop through it.
Piner_phab@reddit (OP)
Thats would be sick, the main problem with a jig for the grease gun specifically is that the barrel end is internally smaller than the main body due to the threads. So its difficult to have a simple tube made of copper or aluminum to suck the heat away.

I love that there is just no secret to it.

If there was a secret would they tell us?

Music was essential 👌
Tonycivic@reddit
Looks awesome! Imo the wildest part of this whole thing is that even adjusting for inflation it probably cost more for you to fix this gun than it cost new.
ThorsonMM@reddit
The US government paid something like $20 apiece for these (300ish today).
Cliffinati@reddit
It's just a tube with a block moving and returning under spring pressure
It's not rocket science
Tonycivic@reddit
Yes I know, but these things still cost money to make. Adjusting for inflation a brand new one would cost about $350 to make. After OP's labor and any supplies and equipment purchases we could be at that mark.

You’re doing the lords work. Stellar job!

Badass

So what's the law, if the firearm was build before the regestry closed you can reassemble them and still register them?
Piner_phab@reddit (OP)
No, parts kits are not legally considered guns. When you rebuild one they are considered a newly manufactured firearm. This particular fire arm was registered as a post-86 dealer sample. These can only be sold or traded between SOT holding Dealers. This parts kit was registered on a form 1 by the Customer SOT. At that point the chopped up parts are considered a firearm again then we did the gunsmithing to repair it.
Tldr: Yadda yadda gun laws are stupid
HefferVids@reddit
Stupid gun laws = legal possession of a fully automatic sub machine gun. Makes sense to me! /s
Piner_phab@reddit (OP)
so much red tape to comply with for a infringement = stupid
Pirat_fred@reddit
Ah so if I buy a chopped up MG42 and rebuild as an MG1 or MG3 I either have to do it semi auto or register it as SOT sample or be someone who can leagly own new machineguns.
What if you found a registered Machingun that was chopped up, could you reweld it and reinstate the registry to make it a transferable again or if once Strike from the registry there is no coming back?
m48nr@reddit
Well done!!!! Hats off to you sir!!!!
RecReeeee@reddit
Impressive work. I’ve heard the DOJ is considering de-regulating suppressors, maybe eventually the MG registry will reopen (or better yet go away) and there will be a much larger market for these.
I won’t hold my breath for either though.
No_Significance98@reddit
But...then the poors will be able to have machine guns too! fans himself with money
RecReeeee@reddit
It would not surprise me if there’s quite a few old fudds who bought up machine guns before the ban that would be oppositional to deregulation because their guns would lose so much equity. It’s just stupid that a MAC11 is worth $15k.
No_Significance98@reddit
costs $15k
RecReeeee@reddit
Good catch, it’s definitely not worth that.

This should be a high school Shop project.

This is one of the many reasons I want to learn how to weld.
A_Belgian_Redditor@reddit
Tig welder?
Piner_phab@reddit (OP)
Yep

Christ on a Motorbike. Good job
