And still hasn't showed up. I did get the rest of it together enough to 
hook a 1.7 volt wall wart up to it, not as bright as it is with fresh 
batteries, which would be 3 volts, but still plenty bright enough for 
this job. Glue setting up on a brush holder overnight, piece of 1/8" 
thick cherry. I've to add the contacts yet, one to brush the brass tube 
for grounding and plus, and a teflon spacer driven into the end of the 
tubeing with a brass screw that will feed the minus to the laser, ditto 
on the other end with another teflon button and a screw thru its center, 
with a piece of 24 gauge wire between the screws. I'll lay a thin strip 
of brass shim stock for both brushes. Tomorrow.

No AC in the garage, close to 90F and 95% all day, had to take a shower 
just to unglue my clothes from me. Gotta find an AC, but everybody's 
sold out till next year. Grrrrr. I'm somewhere near well done. I hope 
its cooler wherever you folks are.
