lost foam glue gun question fluidized bed
- Hello all,
I did some more fish today...First
This time I did them in lost foam, put fins on them with hot glue
gun and then coated them with drywall mud. They came out very good
looking but I have two questions.
The drywall mud came of of the castings very easily except where the
hot glue was...in those areas, the sand is very hard to get off. If
I scrape it long enough it does come off completely and looks great,
but I was wondering if anyone has used something to help get it
I put them in water which seems to help some but it darkens the
metal. Is there a way to get back the silver color?
PS, I made a fluidized bed to put these fish into the sand. I put
all twelve fish onto a main "tree". Then I used a 5 gallon bucket
to bury them in sand. When I turned on the air the tree shot up out
of the sand like a volcano! So I had to rebury it and used just a
little air the next time. How much pressure are you susposed to use?
