Hi all,
The other day I stated that I was going to try to melt some acytel
(Derlin) into an old A arm bushing to replace the rubber. Well forget it.
I tried. I cleaned the inner and outer shell of a lower A arm bushing of all
the old rubber and rust. I then built a Jig to hold everything in alignment.
I used a second outer shell above the one in the jig as a resevoir to hold the
initial unmelted acytel resin. I heated the thing in the oven to 375 F
(the previous days test of melting point). The plastic was too viscous
to run down into desired area. I took it out and attempted to press the
resin in with a wooden dowel. No luck except for about 1/2 ".
I then increased the temperature to 400 F hoping it would thin down
and flow. The plastic simply boiled out of the mold and from the
arid smell, it apparently had started breaking down. I just wasted 2"
of Derlin.
Still need a source of lower A arm bushings.
