My old well abused pneumatic impact driver needed some TLC. The plastic trigger broke. With a punch I drove out the roll pin that holds the trigger in. Glueing the two plastic pieces of the trigger together I drew a rough template on a suitable piece of aluminum. Using a jigsaw cut out the rough shape and with a bench grinder and files profiled the aluminum to shape. A good dose of TSI321 and it's back in service. I just couldn't see tossing this 40 year old tool for a lousy broken piece of plastic.

:) Good save ,Possible cold trigger finger after a while !!
Nice save!
Sweet!!!!! -john
Very nice: good for another 40!
Nice one. Looking at the construction of the rest of it I'm surprised it had a plastic trigger in the first place.
Your last name BcGyver?
Good & clever, Bill!
Isn't it amazing that when something fails first —- it is 9 times out of 10 —- a piece made of plastic.
It is the same with our fishing reels!
Great job!
Best, Fred
Fabricating parts like that is a unique and valuable skill. Think of the cost of new one, and a new one might have more plastic stuff than your old one.
It would have been a shame to toss that driver for such a small piece that was so easily replicated. Glad to have it back in service.
Good job!

Do you think, maybe, possibly, the trigger was non-metal to prevent electric shock? I would not have changed material. Dominick
On an air tool? More likely it was designed to be the weak link so other harder to replace parts wouldn't take the wear.

Nope. It's a pneumatic tool. The body that you're holding is metal so if the tool comes into contact with something energised you're copping it through the grip anyway.
