lyman 450 lubersizer

[gumpy]

i have a 450 mounted on a heatin element. Was using a blue hard lube and switched to lyman regular lube. I noticed that the blue lube was squeesing out of the bottom of the 450, and the lyman is now doing that too.
what is the problem here and how do you correct it.
thanks,
ron

If you are talking out the bottom of the press where it bolts to the bench this is or was a common problem. You can put a large washer under it before bolting it down and that will pretty much take care of that. I'm not sure but I think a piecs of sheet metal will work also.

And keep the bolts that hold the sizer down tightened...

I used a large fender washer under mine to keep the screw from working its way out the botttom. It also stopped the leak but then I don't have it mounted on a heater either. I have seen posts where cardboard was used as a gasket.

gumpy, There's a real easy and 100% effective cure for the lube leakage/extrusion problem. Molly (on this forum) uses shirt- or tablet backing cardboard to make a gasket: Dismount the #450 and cut a pc. of cardboard that's larger than the base by ~1" in each direction. Poke holes for the mounting bolts and remount the #450 as before, making sure the bolts are tight. Then cut the excess cardboard away from the base with a sharp utility knife. Btw, I had the same problem and Molly's solution worked perfectly.

The base access on mine has been punched, like AR-15 bolt key screws. Are they all like that?? Mine has never leaked but I don't use a heater or hard lube.

Then i am going to remount it on the heating element using your suggestion. thank you. ron

I had the exact problem with my 450 with "blue" lube. It took a lot of heat to get that stuff to flow. I made a gasket and that will certainly solve that part of the problem. I eventually decided that the lube was too hard for my liking and I melted it down and re-mixed it to make it a slightly softer lube. Takes less heat and works much better.

My updated 450 leaks a little on the heater but not bad.

I'm sure that most of the leakage I get is from me getting in a hurry and cranking up the pressure. There seems to be a perfect temp and pressure point where the system doesn't leak much and the lube fill is good.

I've resigned myself to the fact that I will get a little leakage and once every 6 months I'll scrape it off and drop it back the the 450.

Gumpy -

Don't know if this is of any interest to you but I rebuilt my Lyman 450 a while back to cure leakage an alignment problems, here is link:

End result was lot of work but all problems solved.
