I recently purchased a used Lyman 450 lubricator/sizer (orange), and promptly ordered sizers for it. Unfortunately the sizer appears that it is not meant for this particular press (even though the container states it was).

It took a couple of minutes of staring before I decided how the parts should fit together, and hopefully I've got it right. I attempted to place the sizer die into the press, chamfered side up (O ring side down), but it appears that the sizer body is too long to properly fit into the hole meant for it. There's a shoulder about 2/3 of the way down the hole in the press body where the sizer hits, not allowing it to sit completely into the press.

If anyone could give me some hints/ideas, I'd be grateful!

Thanks,

I have 2 of the 450's, one orange the other bluish/gray. From what I'am reading I think you've got it wrong. The campher should go into the big hole, with the "O" ring to the top. I push it down as far as I can by hand then use the ram to push it down a little more. I put the keeper nut down over the sizer die, finish pushing it down with the ram (the peice where the top pnch goes), Once I get it pushed down to where the threads of the keeper touches the frame I use the wrench to tighten it all the way down.
Hope this makes some sort of sense to uou.

Thanks for the good advice. I turned the sizer over & it fit like a glove. Another dumb question though. I can't figure out how the lube is supposed to be forced into the sizer. There's a cap (with the bolt sticking through) that simply lifts off, allowing me to drop a tube of lube into the hole, but for the life of me, I can't figure out how ratcheting the bolt is supposed to "squeeze" the lube into the sizer body! There may be a part(s) missing, since there doesn't seem to be any way that it will work "as is". Any thoughts would be greatly appreciated.

Thanks again,

Sounds like your missing a part. There should be a threaded collar with 2 "O" rings on it that fits the threaded post. As you ratchect the post the collar pushes the lube down to the lubber sizer die. Dont get ratchect happy or you will breack the post (done it once). Check to make sure the collar isant down at the bottom (under the stick of lube) ifin its not there you might call Lyman and order one. I just had to order a part for my 450, and the gal said they had most parts in stock.
Not trying to belittle you or anything but do you happen to know anybody that loads and shoots cast. If so try to get togather with them and have them run you through it. Dont know if you have the reversable ratchet that goes with it or not. If you dont get a 1/4 socket and ratchet (1/4 drive works great). and use that. Looking at it from the top to lube you go counter clock wise, to release pressure and bring the collar up go clock wise. Hope some of this helps.

Also have Lyman send you a copy of the little orange booklet that has instructions for most all their equipment- it's free.
I have one of the new 4500 sizers, it was a gift, it's still in the box. I use an old 450 I've had for many years that gives good service.
One caution though, the fine thread nut that pushes down the sizing die and holds it in place is very easy to cross thread if your not careful.
