Denis' pdf lists many alloys with no cadmium. Both 60/40 Tin/Bismuth and 58/42 Bismuth/Tin looks nice.
I believe the expansion comes primarily from bismuth, cadmium really isn't needed unless you need melting points below 95°C.
What I really don't like about the cones is that they depend on both time and temperature. But I may be wrong as I have never used them. I also...
That's actually an interesting point. If the goal is to prevent a fire the outside temperature would be a better indicator that the inside. That...
The biggest problem would probably be that the heating elements would be unsupported at the roof, makes my damnit-radar go *ping* as well.
I like the concept of a physical safety as long as it doesn't require special consumables like cones. The problem is that many metals oxidize...
LOL!
That's still too much money imnsho.
On a bridgeport? Me thinks so. It's not really stable enough for heavy hogging. I also have a 2hp BP on a VDF, works like a charm. The BP...
Now that is excellent advice. A machine is only as good as the availability of spare parts.
The head looks a bit more sturdy than the Bridgeport.
If you're pushing the surface loading on the coils a thyristor or TRIAC based regulator is beneficial. IIRC they recommend reducing the surface...
I think the J had step pulleys for speed control, the 2J has the variable speed. This is the one you want.
Thanks. Like I needed more ideas... One question: How rugged are these units? I tried building a small ZVS driver once, but it was more of a...
Think printable "lost wax"
