Fixing stuff is nice. I'm not overly technical, and I tend to be lazy, but sometimes I really enjoy tinkering and making things work again.
I'm currently working on a plastic ramp from my pinball machine. It's badly cracked and some pieces have fallen off, so stoneshop took it out so I could fix it.
First I glued all the pieces back together and now I'm putting coat after coat of clear two components expoxy glue on, filling the holes and cracks in the clear plastic and making it thicker and stronger. I can't mend it invisibly. But I can make it whole and strong again, and it's going to look reasonably good.
The glue dries in ten minutes after you mix the two components together. I'm using an infrared lamp to heat it up while drying, which makes it harden better. It's great stuff, there are a lot of things you can fix with it.

I think I'll bend a strip of thin copper into shape and glue that to the underside of the ramp, to reinforce it. It's in the middle of the playfield and the ball hits it really hard sometimes. I'm looking forward to reinstalling the ramp once it's finished.

The place is smelling of epoxy and so am I.
But I don't mind.
