    Lyman 55 reservoir

    This is probably a novice issue with an easy fix, but I'm not figuring it out.

    I have a couple of Lyman 55 powder drops I got in a lot of equipment a while back. Both of the clear reservoirs are stained from use.

    One of them screws off. Easy enough, I ordered a new one through Lyman. It came with no threads, but a groove cut around the circumference. No biggie, I'll see if I can clean this one up or use it as is even though it's pretty heavily stained.

    The other has no threads and won't come out. I can turn it, but even pulling on it it won't come out. I'm assuming it has the same groove around the circumference and some kind of detent or something (I don't see a set screw of any kind).

    Any ideas/tricks on getting this thing out? I'm assuming I'm missing something easy.

    As a side note, I got them all cleaned up (they apparently sat for quite a while) and they are smooth as can be. Looking forward to putting them to good use.

    They only made them with or without threads. The ones without are a very tight fit. Try putting the body into a vise and then you can pull on the reservoir.

    Good luck.

    Buffalo Arms used to sell a very nice brass reservoir for the earlier, screw-in type. It was enough longer (taller) that it held about a pound of black powder... handy when loading those big boomers for BPCS. I’ve heard of people heating one of the newer un-threaded plastic reservoirs then screwing it into the body of an old style measure, letting the threads be cut as it’s installed. I haven’t tried it myself, but if you heat that plastic just right it should work.

    You have probably discovered by now that the un-threaded version just snaps in, but because of age and brittleness, it may well break or crack coming out. If it’s so bad it needs replacing, that shouldn’t be a problem. The new one should press in with a little effort and make a solid fit.

    Have four of them, older one are like yours, the newest must use a different plastic as it is still clear.

    The reservoir for the Lyman black powder measure is threaded and fits the early 55 measures.It is aluminum.The Buffalo Arms item is brass.

    Appreciate the info guys! I was half afraid to pull the one too much for fear of breaking it, but I guess if I do then I have a replacement on hand.

    I had wondered about cutting the threads somehow. Didn't think about heating. May give that a try to see how it works.

    Thanks!

    The threaded ones arnt bad to replace with a new one. The press in ones I suspect were pushed in with the body heated forming a size for size fit and binding from the heat. This was a manufacturers way of installing plastic parts into metal or metal inserts into plastic. When replacing the press ins it unusual to not break the old one.

    When I have to make a new hopper for a measure. I look for pyrex tubes if that cant be found in the needed size or one an adapter can be turned up for, then I go to Online metals.com and use brass tubing for the hopper. The pyrex is harder to work with and cut to size the brass is easy to work with and makes a nice hopper. I did one brass hopper with a 1" slot in the front and a piece of clear tubing pushed inside to seal the slot and ends.looks good allows powder level to be seen.

    I discovered years ago that Lyman had gone to the snap in reservoir by ordering the part.I cut threads on the replacement part on a lathe and used the part.Just have to be careful not to crush the reservoir in the chuck jaws.I haven't had to replace the snap in style yet.An Email to Lyman would probably get their recommendation.

    Powder Hopper

    All my 55's have screw in hoppers. On one, it has a thicker walled hopper than the other two. I think this on is an older one. The two with thinner walled hoppers I assume are a cost cutting venture,
    Any way two are very dark. I can't see the powder level through them. One is still clear enough.
    I was shopping on Ebay and found a seller that had a universal type clear hopper. They are about 12 inches long and came with a soft red plastic or rubber top cap.
    I don't recall the seller but I think the hoppers were around $12. I bought two.
    They are the same outside diameter as the 55 hoppers. I tried the heat up and thread in deal. I was a no go. They tended to not thread in and bulged just above were I was trying to thread them in.
    On the one with the thicker walled hopper I thought about using my Dremmel tool to grind out the threads enough so the new hoppers would be a press fit. Even if I had to "glue" them in with something that would be ok.
    Another option would be to take one of the old hoppers and turn down a section just above the threaded part about a 1/2 inch or so. then cut it off. If done right the new hopper would be a snug press fit onto the old hopper.
    This would give me a clear hopper that would still thread in.
    The new hoppers I could leave the full 12 inches long or cut them to what even length I wanted.
    I thought I could cut one into two pieces, one about 4 inches, the other about 8 inches. Use these in two of my three 55's and the 12 inch long hopper in my third 55. this would give my three options on hopper capacity.
    When loading larger rifle cases I use the longest hopper. On smaller cases I use the 8 inch hopper. On pistol loads with light charges I would use the 4 inch hopper.
    Just a few thoughts on how I plan on using the new clear hoppers I bought.

    Not sure if this might help anybody, but a company sells Pyrex tubes is Dramworx. I just recently ordered one for my Redding. My Lyman is new old stock with a crystal clear tube.

    Your wasting your money for Dramworx tubes. I ordered (non threaded) polycarbonate tubing for a couple old Herters from Small Parts ... 24" for 10 bucks plus shipping https://www.amazon.com/Polycarbonate..._dp&th=1&psc=1

    You have to snap it across it your leg like your breaking a stick. It just pops apart.

    My old Redding has 1-1/4” PVC pipe as a resevoir. It holds way more powder than I ever use in a session so it has stayed. Once a farmer......

    Why not just use it as it is , the staining hurts nothing . I wouldn't replace it if it's not broken. I have several that are stained , not much trouble to pop the top off to check the powder level . I treat my vintage loading equipment the same as I do a vintage gun and only replace original parts when I absolutely have to .

    I have been so far. I like to be able to see how much powder is in there and if I need to top off or anything. Plus a bit of me just being particular.
