Building
a Small Molding Bench
for
foundry work

I was tired of bending
over and using a tipsy wheel
barrow for a make-shift
bench.
And storing my foundry sand in a plastic tub was getting old,
too. I had
to wait for it to cool before I could put it back in the tub, or risk
melting
the tub. (excerpted from the plans page)
I drew up some plans and
even modeled it in Solidworks.
I took the cut list to
Lowe's and got one
48" X 96" sheet
of
7/16" thick flake board (.4375" or a little over 11 mm). They called it
OSB for Oriented Strand Board. I also bought the three 2X4s and three
2X2s.
Using the cut list for
dimensions, I cut
everything with a circular saw. I used pocket cuts to notch out the leg
most of the way and cleaned it out with a hammer and chisel. This isn't
going in the living room! It's a good thing, too. I am a terrible
carpenter. I used to frame houses, but I never got near any trim work.
I
threw this together with 2 different length drywall screws and a Makita
battery drill with a clutch. 3" where two 2xs come together and 1 1/2"
where OSB is held to the frame.
The
slats are loose so they can be removed easily. I made the openings as
wide and sloppy as possible so I won't have to fight to get them in or
out.
The OSB has a rough side
and a smooth side. I put the smooth side in.
I
put the flask and rammer to make it look like foundry equipment...
Really I was checking
it for working height. Seems OK for me, but I am only 5"8". YMMV.
This is before the screws were
added to the spacers. They are more even, now, but just as loose.
Quit
laughing! I said I was no carpenter. The 2X2 rails are resting on the
OSB of the ends. It doesn't matter because there are plenty of screws
from the front and back into the rails. The OSB adds strength and it's
needed because the rails take the pounding when you ram a flask.
That's it for now. I
still need to hinge the lid , caulk and paint it. I have a gallon or
gray floor paint...
