What kind of temperatures are you getting? I think I'm barely getting 1100 centigrade. Copper is a struggle.
I'm casting aluminium in a home made greensand. The recipe was 10% bentonite (cat litter) and the rest building sand. The part I'm trying to cast...
Feet. My DIY greensand smells of feet when it's steaming hot. <barf>
I'm not sure a few days makes a great deal of difference. We were in a slate mine recently and traditionally, they had made their own iron cogs...
If you have the inclination, I think you'll find the sintered filter unscrews. Inside you'll find about 3 parts. (You might have to gently dig the...
The nozzles options are specified in terms of angle! I wonder what the difference might be between a 60 degree nozzle and an 80 degree nozzle!...
It's tangential. By design. though the tuyere is now virtually 1/3 the diameter of the internal furnace! So, it's hard to see. I found a damper...
Aa Ahhhh.. THAT's the difference. Thank you!

I've got an Reillo T50 series oil burner. It seems to run OKay. I didn't have any paraffin, but diesel seems perfectly suitable. My furnace has...
Oh, I just got further down the post I've never read the book. Is That how it's spelled?!
It's ... people? Soilet green is ... people?
OK. Cans are out. That clears out a corner of my shed. Make friends with a mechanic. Check. :-)
I've no shortage of dead seals, but my compressor wouldn't last two minutes.
Only one question "forced air". Does that simply mean I need to force air with a blower? The reason I ask is that it looks like the "simplest"...
100% correct. I was reluctant to dispute with my learned friend above on account of me being the new guy. The increased frequency makes an...
This completely computes. I've already made my first mistake in that most of my cans are crushed to save space, so removing moisture can't be...
With apologies "side tap a foot or so back" probably means something to someone who knows what they're talking about. Needle valve, I get (I'm old...
