Chainsaw Repair

Bought these a few weeks ago, cast aluminum. I wonder how old these are ? 

Nice find Fisaw.

A decent spinner / breaker set is not mandtory, but very nice to have - the 'right' tools usually are.

I have a Granberg 'Break-N-Mend'.  It works.  But I would not want to do a lot of chains with it.

You can buy a pocket chain breaker for $17 shipped off of eBay (photo), and peen over the rivets with a small hammer.

I figure that 'in the field' I could remove the heads of rivets with a round sharpening file and wedge the pre-set off with a screwdriver, then peen the heads over with a rock, if I had to, and if I had replacement pre-sets and tie straps, since the original ones would likely be damaged.

Using the breaker instead of filing lets me recover and reuse most tie straps, without damage.  Using the breaker anvil, and a scrap drive link as a die, I also can drive the rivets from the other tie strap (pre-set) and reuse that. Color me 'frugal'.

I would not reuse a full pre-set unless I had to.

My old Stihl breaker has been good over the years. Recently bought a spinner off of Baileys a few years ago.
1st pic shows part#for the Stihl punches.

2nd pic shows a fullhouse 1/4" carving chain I built out of 2 loops of chain. Did it with the break n mend Grandberg back in the day when I graded lumber at the lumber division. During lunch and coffee breaks.

Was looking at some carbide insert harvester chain ('Chain-Serts') - their repair instructions specifically said to peen over their rivets with a hammer, suggesting that they could ruin a spinner. Not sure if the Oregon DuraMax spinner / breaker would work.
