Chainsaw with broken points arm

[Propane1]

So, any ideas how I could glue this back together and what to use. It has been glued before by someone.
I’m guessing it’s a 1960’s to 1965’s or somewhere around there XL12 Homelite chainsaw. Not something I’m gunna use full time. Just a neat old thing to have that may work. Just for fun, as my father would say.

Possibly JB Weld, Fiberglass Resin or construction adhesive - the block is probably a type of phenolic material so would need something that might stick to that material. I would suggest cleaning any adhesive off and dry fitting the two pieces together and then narrow grooving both pieces about 1/4" long on the sides and drill a small hole crosswise in each portion. Then use a paper clip or similar metal bent like a U formed staple that could be inserted from one side and then bent over on the opposite side to add strength. Then once you form the U staple you could bond them and then add the staple for strength. Probably be better to get a point saver module and do away with the points if you cannot purchase a new set but your time and money. Maybe someone you know with a 3D printer could print you a new block pieces that you could connect to the metal pieces? Just a few suggestions for what they are worth.

Thanks Stew. Im getting lots of suggestions. I’ll be doing some thinking.

I will try to remember to look in the morning but I think I have a complete XL wore out in a box up on the shelf.

Yes I have Chris. But I’d like to try and fix it. I’m kinda strange that way.

The parts saw I have is a Stihl 75 and not an XL like I thought.

Dang Noel, you must be bored, but with all that wood cutting I wouldn't think so---LOL!

Sorry, I would throw those points away and try Chris' idea if new ones are not available any more.

Well, the points arm is fixed. And installed back in the saw. Still have to put the flywheel on and see if it will work.
If it works, I’ll post pictures of what I did to fix the points arm.

If it works, it wasn't a dumb idea.

I’ll bet it goes a long time. Nice job
I’ve gotten to where I mix some fiberglass in with the JB weld for extra strength and it has worked really well.

Good job on the rebuild Noel. I don't think they makes points that the contacts match up when closed.

Are you using the fiberglass resin or fibers from the mat? I'm thinking probably the resin w/o hardener.

Sometimes I wrap the part with lightweight fiberglass cloth and then rub the JB Weld through it to the base material. Other times I take of the heavier fiberglass cloth and just chop it up with a pair of scissors and mix it in with the JB Weld before applying it. Either way you have to put a layer of JB Weld between the two broken parts before the fiberglass is applied.

Sounds like a good combination. Thanks for the information.

Great job Noel, nothing like a challenge that was successful.

So used the fixed up Homelite chainsaw to cut a bit of wood today. Worked great. Kept forgetting to use the manual bar oil pump. Hehe. So use to the automatic ones.
Was a little fussy to start and keep going, but after a few minutes it was fine. I’m a little fussy to start and keep going at times too. Hehe.

Looks like a commercial logging operation, Noel! You have a full time job again!
