Ditto “Bil”

The guys that complete their parts sets with ColdSteel receivers are adroit craftsmen to say the least, and have balls as big as Tiger Tanks to undertake the challenge.

I would be very curious how many "80% receivers" ColdSteel sells annually and how many become functioning firearms :?

I'm glad you guys were able to say it nicely. Really -- if you were a manufacturer, would you be proud to send those out to people who have paid their hard-earned money for your supposed skills and expertise?

I bought a PPSH41 trunion from Coldsteel and was just shocked that they allowed it to leave their shop in the shape it is in. It has gouge marks where the barrel hole was drilled. But I kept it because I can make it work, and nobody else was offering one at the time I bought it.

Yet, they seem to do a good job on the flats and other receivers they offer. In these cases, it's just a matter of bending metal, and they apparently do well at that.

But the MG42 receiver is obviously way above their heads. Just compare it with the other receivers that are being offered.

I agree with Bil and Prussia. You guys that manage to make a working SA42 out of these :shock: --well, my hat's off to you.

Thanks for publishing the pics. A lot of people have been curious about the ColdSteel pieces.

The buffer and stock match up pretty well and the recuperator sits in nice and flush. As soon as I finish milling the grip and ejector opening I will post more photos.

I haven't taken any photos yet,but I hope to post some tommorow; was planing to be almost finished by now,but I have had to use a dremmel and my drill press ONLY!!!. Still I'm within .010" of all measurements :pound:

I have a question about the feed tray: Does it sit flat on the receiver or is there a slight amount of pressure needed to close the top cover? The problem I'm having is having to use a bit more force than I think is needed to close the cover.The top cover fits great by its self,however when the feed tray is fitted the top cover stays about a half inch from closing, it will close and latch but, it feels like it requires to much pressure to do so. I have ground a bit of the front of the receiver where it was binding and that helped a lot, I just don't to take too much off. Any help out there?????? PLEASE!!!!!!!!!!!!:bang:

Thanks

You can remove a little off the feed tray if needed. Would take more off the receiver before I started on the feed tray.

Sd.,
Is the problem simply a matter of adjusting, [say bending], the feed tray mounting tabs?
With the feed tray mounted with the cover pin,will it lay flat to the receiver?Will some "adjustment" let it lay flat ? after a little "adjustment" my feed tray fit quite well.On a re-weld however.
food for thought,cz2.

Question on the ratchet plate,I got one from RTG and it does not have the holes for welding that the pics in priates build has. Should I drill some to weld in or just weld along the edge? Thanks.

I bought some flat rivets from ACE hardware and with my small lathe turned the head down so that it would have clearance with the slots in the bolt carrier. Good luck.

Bil may have some rivets left that will fit, he was giving them away. Send him a PM

Thanks bolex thats what I figured. I have another question on the ratchet plate; By the looks of it the cocking handle is held in a grove in the plate itself, should I thin the handle arm to fit or enlarge the grove?. Sorry for the bone head questions. :brain:

Thanks

I would slightly enlarge the slot-check carefully as you don't want it too loose.There is not enough meat to thin the handle,in my opinion.If you widen the slot.try to do it before you weld it on,it is easier to get at,although an almost wornout cutoff wheel in a dremel works. When are you going to ask the bone-headed questions?? :? ---bil

Well jbaum the way I meant it was fixed as in I finally fixed all the stuff I had bought to make a working SA53! But I guess I should have reallized it could be thought of that way as well! It seams like sd.kfz.173 is making good progress! Keep it up and you will be there in no time!

Also sd.kfz.173 have you cut the slot that the charging handle rides in on the reciever itself? Its more of an interupted slot because it is cut into the "bumps" that stick out but is not cut deep enough to cut into the "troughs". I hope this makes since!

Thanks Bil ,belive me if I haven't asked one yet I will!:-) I haven't welded the plate yet so openin it up will not be a problem. :thumbs: Thanks for the information mattcdavis,I think I get what you mean but if you have picture of the slot,it would REALLY help.


Thanks

If you do some pic searches here,or on google, you will see the slot I mean. It is actually on the reciever itself and really looks like an interupted slot. I don't have a camera anymore or I would try to get some photos. Let me see If I can find one.
