Pocket Chain Breaker
By: Philbert Date: March 19, 2017, 10:15 pm
---------------------------------------------------------
A lot of 'old guys' say that these are all that they used to
join or repair chains in the field. I mentioned these in
another thread, and wanted to try one: found an Archer brand
model on eBay for about $18, shipped.
The tools comes with an anvil (bottom in photo) that is similar
to the one that came with my bench top breaker punch (top in
photo); a punch to drive out the rivet; and a concave punch -
presumably to shape the rivet head? There were no instructions.
Maybe I was doing it wrong? But I was pretty disappointed.
Ended up having to use a fairly large (24oz) ball pein hammer to
drive out the rivets on some 3/8 low profile chain. Ended up
deforming the links too. I suppose that I could file or grind
off the rivet heads first, but then I probably don't need this
set - could probably pry the tie strap off with a small
screwdriver.
I was able to get better results with my Granberg Break-N-Mend,
and much better results with my bench top chain breaker.
Would like to hear any tips or advice from guys who used these.
Maybe the $40 Oregon one is better and worth the extra $?
Thanks.

Note, in the photos above, that the pocket breaker anvil also
did not have any recesses for the top plate of cutter teeth (see
image from Oregon M&S Manual). This means that it only really
works for links where there are tie straps on both sides,
limiting its use.

Helps if you grind the rivet head off before punching it
through.
Looks like you bent the heck out of the drive link in pic.

Trying to avoid that - if I have to grind (shop) or file (field)
the head off, I can probably pry the tie straps off without this
tool.
I think that this punch may also be large for the smaller, 3/8
low profile rivets. Will have to try on some larger pitch
chains.

Full disclosure - that drive link was already bent - part of the
reason that this chain was in my 'scrap pile'.

You can't reuse a punched out preset link if you grind off the
rivet head.
Trick is out in the bush you need a flat solid rock to lay the
anvil on or a soild chunk of iron on a skidder blade.
Granberg break n mend works the best with the adjustable anvil.
3/8 lo pro chain should be used in the .325 anvil slot.(or .250
can't remember)

On this model, the 3/8 low pro chain fit best in the .250 slot.
But I think that punch may be too large for it. It is noticeably
larger than the punch in my bench tip breaker press.
Tried it with full sized 3/8 pitch chain. Still disappointed.
JMHO
