K Horn mishap

Postby Mafarnz » Tue Jun 04, 2019 7:48 pm

With the near removal of decent paint strippers from most stores I’ve been looking for an alternative. Recently I’ve been trying to burn paint off with a propane torch. It has worked well on Leslie bells and manifolds. Today I tried it on a K 4A bell and well...

Here is an undamaged back cap on the bell.
My guess is that K horns have a higher zinc content than Leslie used.

Gosh, that's a real bummer. Did it take much time/heat to cause that to melt?

BTW, Tractor Supply Company still sells the old style KleenStrip stripper (at least in their stores back east). I just bought a gallon can today. Powerful stuff, but it does the job.

That really sucks Matt,

I'm also really bugged that all the stores around me removed all those great paint strippers from their shelves, the last time I found a can of that paint stripper was about a month or two ago and that 1 gallon of stripper cost me around $50.00 JUST FOR ONE GALLON????

I think it's time to invest in a sandblasting cabinet, or you could hire me to do it, I do cheap work

Here's some of the work I do if anyone is interested

Very sorry about the bell,

Sandblasting ruins the finish of die cast K bells, so if Matt was going for the die cast finish, sandblasting wouldn't work. Even walnut shells or red garnet messes up the finish.

Aluminum oxide is best for stripping horns, never use sand.

I don't believe in abrasive media blasting (e. g. sand, glass beads, Al2O3, etc) any die cast horn bell or part. It ruins (changes forever) the smooth die cast surface finish.

Matt, what did you do to that poor thing, put it in a ceramic kiln? :lol: :lol: :lol:

Was using a large weed burning propane torch to burn the paint off. I’ve had good results doing it on Leslie bells and manifolds. My guess is being die cast, K bells have a higher zinc content and do melt and bubble much easier.
