AGAIN!!!!!!!!! *update*

The way you have that mounted is totally irresponsible.
At least put a steel plate under it to support the overhang.
My goodness, some of you folk.


There you go with that logical thinking again Sir....
Shoulda bought the upgraded press...the Rock Chucker press that is and we wouldnt be discussing this.
I agree the jr press is a light duty press and needs to be handled with little white gloves.
But, RCBS did stand up the first time for the guy, no?
tight Groups,

I say design flaw and maybe some quality control problems. Could be press mounted a bit too forwards didn't help things.
I don't have a RCBS, but just looking at pics of the newer ones and even if the press is mounted all the way back with the arms rubbing against the bench there is an enormous moment arm (or cantilever) sticking out from the bench. The cantilever portion should be supported as the two bolts on either side of the press are the pivot point. The bench could be notched to recess the whole thing and support the casting around the ram (but kind of screws up your bench), or have a good steel base (1/2" thick) made that will extend the support the to casting portion around the ram.

I did that exact method of mounting in my first press, and it never moved
 
I'd use at least a piece of 3/8" steel plate under that press, and notch it where the arms come down. Also use some good size washers underneath when you bolt it down. Check the bolts for tightness once in a while as well, if you use softwood on your bench the wood will compress over time.
 
For my small Forster it's mounted on 2X6 planking and then clamped to the bench as needed, the Dillon got bolted to the steel bench with the high mount..
 
I have bought second hand gear, specifically RCBS and have not had an issue getting it replaced at no charge, not even shipping. I emailed the RCBS website and got a reply back within 24hrs and new parts within 10days. This was for the arm on my rock crusher that elongated the hole on the press.


Doubtful it was a second hand gift
 
Looks Like It needs to be bolted to something more solid that won't flex. I could be wrong but it looks like the front part has sunken down into the wood.Which would flex creating leverage then snap.if it's cast iron then it's brittle at least from the pics it looks like cast .
A lot more of a procedure to weld if your doing it properly than steel.So if they won't exchange it. Get a welder don't try to fix it yourself. A little job like this you can probably get done for some ice cold frosty ones or pay somebody it'll take the guy longer to prep it than to weld it
