That's a fair question. It leads to other high technology ingredients for the successful founder. You need a clock and a means to measure weight. So, how...
Sounds pretty good. I was also thinking of an old fuel pump from the junk yard (or one of my vehicles--not much difference ;-) I looked at a website for a...
Doc, You have brought something new to the table. Not the cutter, but florist foam. Has anyone tried that crumbly green stuff for lost foam casting yet? -Ray...
Tom. The rammers came with a consignment I bought. The rubber looks just to be hard black stuff like tires are made from. It sure helps to prevent dinging up...
I had trouble yesterday joining Home Foundry. It gave me a whole bunch of crap about not being a registerd user with "hellow rbrandes" at the top of each page!...
That's been in the back of my mind too. I've seen odd shapes of foam at hobby stores like Ben Franklins for years-- cones, squares, spheres. It's not...
Well, if it was sealed... Being opencelled there may be less foam to burn out. I have noticed on really big castings I get voids in the risers and I think...
Florist foam has a much higher density, and consequently, requires much more heat to evaporate. It also creates a lot more gas. I have used the green foam for...
Ummmm ... instead of spending money ... why not drop by your local HVAC dealers and scrounge up an oil furnace burner from their scrap piles ... for free! You...
That crumbly green stuff is called oasis (may be a brand name). It is designed to hold lots of water, to keep the flowers fresh. Sounds dangerous as a lost ...
Don, it sounds like you've got the best idea yet! ... __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in...
John, A pyrometer is an essential tool that doesn't have to be very expensive. That PM article is good for explaining how it could be done from scratch but it...
Thanks Fred! Up until now the only thing I kept in my notebook was the furnace and burner designs, propane pressure, and amount of time the burner was on. I...

Tom, Thanks for the heads up on the green foam. Now I won't have to become a grave robber! I have been pouring on foam at 1375. I will try the next one a...

The local foundry has a cuppola and an inground cruicible furnace which he built fired using an oil furnace burner and a blower...he only uses it for ...
Received your video, three days ago but of course tv broke the same day...It's fixed and I have just finished watching the video for the third time in a row....
... With all the talk of homebuilt pyrometers, has anyone used a thermocouple from a gas hot water heater? IIRC, they are k-type, sealed on the end and made to...
K2, I second Jim's recomendation. My casting were mostly junk until I spent $200 and got the Mifco. Now everything is wonderful! Casting without a pyrometer is...
I, for one , think it's worth trying out. Even if it doesn't work, you'd have a hydraulic pump ready to use for some other project. You'd need to adjust the...
You can buy castable rubber in several grades of hardness from MSC and other machine toll supply houses. The trade name of the stuff is Devcon. buy the 90...
