What's your best McGyver repairs?

[alexcagle]

Ever had to make do with a broken part, and was able to repair it with shear ingenuity?
This is on a TS760 Stihl. This has held up for three years so far in commercial use.
The vertical bolt is drilled and tapped for a concealed bolt that links the two pieces together tightly.

The "springy" wire on the "easy arc" start mech on my Pioneer P26 broke, fashioned a replacement from piano wire & it's worked faultlessly for the last 10 years

That is a great looking repair, I think we all have had to fix a handle now and again. I did something similar to a partner about 10 years ago and it is still going strong.

Sort of like this oldie

Wish I had a picture still, I used a brass pipe union and had to grind it down to slip inside the broken handle of a ts420 and then riveted it in place, Still holds perfect. owner didn't want to spend $40 on a new handle

They cost more like $60 or $70 from Stihl.
They make a good aftermarket one now.

I used this fiberglass water activated repair tape on stuff like that. It's similar to what they use for making casts for broken bones. It's in auto parts stores around here. This stuff is the bomb.

I wasn't gonna pay $15 for a slider kill switch. Ran an extra wire and used a computer power supply switch. I didn't cut plastic to seat it...I may have an attack of OEM at some point and want a real one.

I have one of those saws in my bone pile. It's a 012 with a good 40mm cylinder. The oiler didn't work. So it's for parts now.
I'll see if the switch is still on it, plus it looks like you need a carb adjustment grommet. The big hurdle on those saws is the oiler. Too expensive to replace, and parts are getting harder to find.

Don't toss those rare pistons.or any pistons.
Patented repair for pistons that don't need any warm up.Fire up the engine and go WOT any application.
The copper provides the sliptivity till all the atoms aline themselves.

Recoil grip on homelite XL broke so whittled groove around the circumference of a piece of 5" long 1" dia. branch, tied the recoil rope around the groove. That was a early 1970s saw and it still runs with that fix today.

Isn't that Catalytic convertor material?

The throttle linkage on my 076 snapped so I made a new one out of a bicycle spoke, they are the exact same gauge & hi tensile too which means heating the wire with a MAP torch where ever a bend is made.

Ripped the av bushings in my dad's craftsman 3.3 and replaced it with some appropriate nut bushings. No antivibe but it ran, till some a$$ hat stole it.

Not on chainsaw and don't have pics so kinda worthless but I fixed the gas tank on my sons dirtbike yesterday. Was having leakage around the press in fitting so I yanked it out and threaded a barb fitting through the plastic with gas resistant teflon to seal then put the press in fitting inside the tank and was able to catch the threads on it and sandwich the plastic for a solid hold. So far no leaks! Once I find a new tank I'm gonna replace it though. Not a fan of weird mods for gas tanks

I’ve done many thru the years but my latest is using a plastic ketchup bottle for a temporary fuel tank.

Give it a good squeeze and it will start first or second pull.

Runs ‘till the bottle goes flat.

The above setup proved the new fuel filter was trash and there was nothing wrong with the carb.

Here, just to avoid having to dump fuel from a ginormous powerhead.

Stripped TS420 muffler threads hack.

Drilled behind flange, used a bar adjuster nut which is 5mm, drop it down the drill hole and pull the hose off after the screw is started. Plus it wont spin in the round hole. Works great.
