Greetings all; This afternoon I unpacked some brass tubing, the same size as what the 38 special laser was made from, and stumbled over a short piece of 3/8 SS tubing a neighbor had given me after he had redone the fuel lines in a local race car. So I made a pipe nipple with .5mm threads out of the stainless, shaving it .1mm at a time until it fit the threads in the rear where the batteries are held. Made it about 10mm long, and cut it off, screwed into the rear of the laser. Then I unpacked 1 or the 3, 3' brass tubes I had bought, and inverted and reduced the code until it had cut the same thread internally, then screwed it onto the SS nipple.
Then tried to cut it off about 2" longer than the rear of the spindle but my 50 yo tubing cutter got slightly out of square and screwed itself up against the adusting nut before breaking off the tubing. Darned near too short, depending on the slip ring extension. By then it was dinner time+ so I quit for the night. I'll thread the second tube tomorrow, and mark it for length for cutting after I turn it around in the lathe. Then figure out a design for a slip ring insert and brush carrier so I can power it from a small wall wart. Eating $15 worth of batteries per 30 minute run time doesn't have a good flavor to me, and I've wall warts by the bucketfull. And I've teflon enough to make the slip ring holder, just need to find that round tuit. :) The variable ND filter has not arrived. Progress, sorta. slow motion like me. ;-) -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
