Moulding Flasks ,,, Steel - RobWilson - 02-26-2012

Hi Lads

I made a few steel moulding flasks for my foundry set up a few years ago ,, in the past i have always used wood flasks , these are fine , but can were out quickly ,and do burn when you have a spill . Slaphead

As with nearly all of my projects they come about due to getting some free material Big Grin

. I scrounged a few 1/8" x 4 1/4" steel off cuts from a customer i was doing a bit work for .

First off i need to form a bead up the centre of the strips so that the sand will have something to key to , so i came up with a quick and dirty swag tool for my home built shop press .

The lengths were fead through 6" at a time to form the bead.

Next up ,, four bits of 4" steel bar were tack welded to the welding bench to form a bending fixture .

Using oxy gear the bends were heated and bent .

The overlap was then trimmed and welded.

Re bar was used for handles

Rob,

Nice job on the flasks but how did you keep the rib from going flat when you bent it? Chin

when ever I try something like that the bead or rib as I tend to call them go's flat in the corner. Slaphead

I don't see any distortion in yours at all.

Looks great!!

Rob,

Nice welding. How was it welding the re-bar? I was told not to bother trying to weld re-bar because it doesn't weld worth beans. I think I may have been led astray based on how good it appears to have welded for you.

Very nice job on the flasks they came out superb. Weldinbg rebar is ok it is just a low grade steel, the weld is usually much stronger thyan the rebar so one can't depend on the strength in a butt weld at least that's the way it was explained to me. n tom
