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.

It may not be very productive,
but it's sure going to be interesting!

Nice one. Looking at the construction of the rest of it I'm surprised it had a plastic trigger in the first place.

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!

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.
Fishing tackle is an art form and all fish caught on the right tackle are"Gfish"!

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.

Do you think, maybe, possibly, the trigger was non-metal to prevent electric shock?  I would not have changed material.  Dominick
Leave the gun.  Take the cannolis.

There are two things I don't like about fishing.  Getting up early in the morning and boats.  The rest of it is fun.

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.
Any machine is a smoke machine if you use it wrong enough.

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.
