Leaky Lyman

[King Medallion]

I have an older Lyman 45 Lubrisizer, and it leaks out between the bottom of the unit and the heating pad. How do I fix it?

My 450 may be different on the bottom?

To much heat makes my soft lube exit the bottom, when to much pressure is applied, turning the lever.

For each bullet, size bullet to bottom of die. Now turn lever to push lube into bullet grooves. Just enough, not to much.

I use an old heating pad when room temperature is below 75F degrees. Its adjustable, low, med, high. Its wrapped around the upper part of the sizer.

Lubes melt at different temperature. I use the softest 50/50 . Currently using RCBS Pistol Lube.

Seems to leak now matter whether the heater is on or not. I usually throw the lever 2x every bullet to get the bullet grooves full, I don't crank on the screw lever much at all, just to not over do it. There is no temp adjustment on my heater.

Search at. edit/add. See Youtube.Rebuilding a Lyman 45 , parts 1 and 2.
https://castboolits.gunloads.com/forum.php. The fix will be different for the 45.

Looks like some place a piece of cardboard under the unit. A call to Lyman may help?

Interesting. My room is in the basement, usually around 65-70 degrees. North Illinois. I'll give cardboard a try. My other Lyman 45 I used with SPG only lube, no leakage on that one.

That part is not threaded into the body. Your pressure nut is now engaged and if you push that rod back into place the nut will slide up in the tube. The threaded shaft is held in the body by your bench. It rotates freely.

KING: What is under the base of that Lubrisizer?

You need an absolutely rock hard/flat surface.

FWIW: I run four of the 450s (including two old ones)
They are mounted on simple $2 mending-plate shims from home depot.

Mounted to the heating plate, which is secured to a century old oak 2x10 plank that is my part of my bench top. Painted aerosol blaze orange in 1978 when I was 15 years old at the time I built it. Rather proud of it.

Still... something's not sealing that base surface flat....

 

[King Medallion]

Hmm. It's the same setup as the other one that doesn't leak.

Well.......................something is certainly askew if it is leaking......................

It's a good thing that wood doesn't warp.........................

I bought a new Lyman of that style years ago. It leaked right out of the box as you describe. Lyman said to restake the bottom on, or send it in and they would. Instead I just placed 3 or 4 pieces of thin cardboard cut to size to fit the bottom. Not the whole sizer, just small circles to fit under the base so when bolted to a heater it would push the the circle not painted in orange up against the base. Never had another problem after that.

Today I took the Lyman out with a heat gun and cleaned out all the old lube, and discovered a broken O-ring in the bottom. Also it's a 450 and not an old 45 that I thought it was. So I ordered a couple sets of rings for it, and also got 5 tubes of White label Carnauba Red lube for it. Ready to rock for the weekend, after golf!

Glad you got it figured out and let the rest of us know what it was. I like easy fixes every time. I have found the more you work with a particular machine and solve it's problems the easier it is to maintain going forward.
