Chainsaw Repair

tinker, I did try a roll pin the first time I did it. even with a proper sized pin for the hole, after a week it ended up working itself out and wearing through the plastic of the head, locking it in place. I've used the roofing nails in the past on other projects with nothing but good results and decided to try it here. the one good thing about peening both ends is that pin isn't going anywhere. the nail is soft enough to peen down nicely and strong enough to hold much more abuse than the knurled fit.
