How big are the mounting holes on a Lee Classic Cast Breech Lock Press?

Hello!

I'm building a fairly portable reloading bench that can be C-Clamped or bolted to a variety of tables and such, and need to know what diameter bolts to buy to mount the press to the bench.

I looked over the manual (http://leeprecision.com/cgi-data/instruct/90999.pdf), but it doesn't say anything about the mounting hole sizes, or list the bolts I'd need in the parts list. I'm guessing 3/8ths, but guessing doesn't always work :)

Can anyone that owns one specify that, please?


Additionally, I figured out why I could not close the bolt on some of the dummy rounds I made with the lee classic loader. Brass needing FL sizing was a good guess on the part of some of the members here, but that turned out not to be main issue. Actually, the neck sizer hole was drilled at a slight angle. I'm thinking maybe 20 to 30 minutes of an angle. The end result is that no matter what I did (and I tried a lot of things, including rotating the die a small increment per tap with a hammer. Certain increments yielded more-true, but not-true-enough bullet seating), I couldn't get a bullet in there straight and that resulted in one side of the throat sheering one side of the bullet 100% of the time, even on the cases I could fit in there. The angle is visible when a sized case is still in the die. The sleeve doesn't 100% fit the case (ie, it's loose) and when the case is fully hammered in there, consistently, one "side" of it does not make contact with the sleeve. Ideally, contact with the sleeve would be uniform.

So scratch that classic loader. I bought a classic cast breech lock loader and some decent dies, including a FL sizer which I would have needed anyway, sooner or later, and now I can also reload for my Remington model 81 in .35 Remington, too =)

Don't know what size bolt holes are in the press, but the Lee bench plate mounting kit that fits all Lee presses comes with 1/4" mounting bolts, washers and nuts.

pretty sure my turret was 1/4

The Classic Cast Turret / Pro 1000 mounting holes measure around .29" - .31" but I am using 1/4" (.25") bolts.

Remember, anyone who answers, what length the O.P. is likely to need. Clearance to get your fingers on a wing nut or however you tighten the bolts might make a difference.

Lee will replace a defective die. You haven't thrown it away, have you? The Classic Loader is neat to have around even if you rarely ever use it again.

If you don't get an answer about the diameter, check out this drawing
http://www.leeprecision.com/cgi-data/instruct/TMPCC.pdf
While the holes are not dimensioned, they are proportional, so you could print it out and measure the holes in the drawing to the dimensions which are given and calculate the diameter.

Or, email Lee tonight and have an answer tomorrow sometime. Their turnaround on simple questions has always been one day for me.

Is there an issue with measuring the diameter on the press?

Unless you are very precise with the holes, your bolts may not line up with the press frame/holes. ;)

When I am building a relading bench (currently building 2 more for new reloaders I am helping set up with 2 presses each), I will usually drill slightly larger holes than the 1/4" bolts to give me some wiggle room. :D

Thanks!

@Lost Sheep: The bolts in the package likely won't be quite long enough for this application, but judging by the holes in the diagram you linked to, the diameter is somewhere between 1/4 and 3/8. 1/4 should be fine, and I have a lot of 1/4" bolts/washers/nuts already.

That spec sheet is pretty handy. I can go ahead and send the base to my drill press tomorrow =)

@Boxhead: It hasn't shipped yet.

1/4 bolts fit with just a slight area of wiggle.

All of my four LEE presses use three 1/4" bolts.

There is to most of the peeps on this forum...the OP has been posting for 7 years; and he still doesn't have a clue...

Actually, I do have a clue now, thanks to the "peeps" on this forum =)
