Used them in a different light.
Mine was not threaded, just set in there. But I have already had my suspicions it was not a genuine piece.
Was thinking if I do this, of making/buying completely custom guts for it. Probably along the lines of pressing in a slug of aluminum (or copper if I splurge) to make a integral shelf for the mcpcbs to be screwed down on. No need for it to be removable. I can get to both ends, and plenty of room to solder the wires with them in place.
Even then, limited run time on high.
I enjoy the fabrication as much as anything. Practicing my machining skills, and finding workarounds for the tools I don’t have. Like to think I am fairly good at that kind of stuff.
Still learning on the electronics side of it.
Not a new thing for me, pushing the heat issue a bit.
Just put together a DD MT-G2 @ a little over 3.5A on 14500s, around 22-23 watts. Size = 17.4mm Dia. X 158mm long including switch, all copper.
My first MT-G2 build-copper smoothie (prototype anyway) Gets hot pretty fast. Couldn’t wait for the driver to get here so I can have some lower modes with a bit more run time.
Will have to tear it down and rebuild when the driver gets here. Still a lot of work to do on that one before I get started on another.
