Wow! You men are Masters!

casting your self or getting them done? thats the expensive and difficult bit is making the patterns for the moulds.

We made our Own New Patterns to Blue Prints. Then Myself in the foundry. Making Cores and Moulding and Assembly Including lots of drilling to vent etc.

Making the Patterns is the EASY part. Trying to get the Hot Metal to RUN and fill the Double Cored Area is the HARD Part. Down to Critical TEMP of Metal and Pre Heat Burn Out of the Mould before the Pour. using a chimney system to help DRAWN the Hot Metal.

Myself. at work in the Sand Pit. Apologies for Photo Imagine Quality. But Bear in mind after spending 8 hours working inside this Environment. A Good shower is needed.

In the Photo above, Thats Myself using a wooden stick after pouring Spirt down the Vents and Igniting them with my stick on fire . Note at Arms length. Thats as Close to molten metal you will find me.With One Ton of Molten Iron in that Crucible hanging from the overhead crane straight from the furnace manifolds are Pour No 2,3,4. We need the Higher Temp and a PURE Metal Fill. Hence the 1st pouring will always have some small impurities on the Top.

Back to Working with WOOD and a Shrink Rule LOL CAT 8C20 Heatbox

The morning after the Pour. Using the overhead crane and chains to remove the weights and steel girders. Out of the Sand Pit to the Knock Out Area. Yeap using a Sledge Hammer to remove the Sand to Find the Raw Casting. Then using a Small hammer. Hammer the Casting to break up the sand inside the core jacket and Poke about inside the Core Holes to get sand out. Then Load into Shot Blaster. Fettling Up with a Grinder then Machining Up. Followed by a Pressure Test on the inner core to check ALL GOOD. High Temp Alu Foundry Furnace Coating. Box up.

Cat Cave castings are the Best quality ever pattern making is truly painstaking work my dad was a pattern maker and he would talk about his workto be able to make the pattern for the mold and have to size it for the shrink of the molten iron his work was always to plus or minus one thousandth of an inch he would hand sand the piece by hand
