Straightening a 2" bar Andrew Mawson 01-28-2008

I have a 2" diameter bar of steel 36" long with a 1" 'droop' in the
middle. This is one of the two bars that the fork lift forks slide on
on the front bucket of a JCB so it is likely to be a bit stronger /
tougher than mild steel. Is it feasable to straighten it under a
hydraulic press, or should I fork out (sorry!) the £70 plus vat that
JCB want for a new one.

Will straighten easily with a hydraulic press and vee blocks(steel
ones).
Don`t know about the pin for the forks but the 3C 1.3/4" bucket pins
are mild steel according to a spec a customer got from JCB in order
for us to make pins that they could not supply quickly.

Interesting Mark. Now all I need is someone local with a darn great
press as this is a meaty bar! Incidentally, 3C & 3CX use the same
buckets & pins and are available from numerous places at £12 a pop.
There are three lengths, (9 & 12" buckets have shorter pins and
everything above that uses the same ones).

SO.... anyone in East Sussex or Kent / Sussex borders got a darm great
hydraulic press ??????

It's bad enough picking up a pallet when it it TOTALLY obscured by the
6 in 1 bucket (particularly at the moment with one drooping fork),
nevermind prescision thumping 2" bars, but I like your thinking ! I
suppose I could stamp on it with one of the rear stabiliser legs.
