New Lyman top punch won't fit into Lyman 450

[Tippet]

it goes in about 1/16", then gets tight and won't go further. the old one slid out of there real easy, what's the deal? Do I need to sand this thing down to make it fit? Am I doing something wrong? I tried heated the 450 up in the oven a little, same as when I cleaned it up.

Make sure the set screw is backed out, better yet take it out all to gather, you don't need it. A little grease will hold the punch in. Also use a mike or verniers to measure BOTH shank diameters. No point in sanding it down if it is correct Dia.

Larry has some good points, measure first. I have gotten 1 that was cut too big to fit in my luber though, so it does happen.

I had a new one a few years ago coated with a waxy type substance and it wouldn't slide in. Cleaned it off with lighter fluid and it slid right in.

That happened to me on a new top punch before also. Chuck it in a drill and use sandpaper or a file to remove a little metal on the part that goes in the ram, stop when it fits.

Yep, drill press and sand paper worked for me, too.

Thanks guys. Yes I suppose someone had to say it, but the problem isn't the set screw. I'll try the drill and sandpaper.

Yes that wprked well, the top punch slips right in there now. Thanks guys.
