meanwhile out in the garage ...

Any one of the four @Handy Andy . This was actually the first. before the replacement sprockets from NR6C.
Notice all of the sprockets are cracked and I had tried (unsuccessfully) to clamp them their hubs with circlips. Complete waste of time.
I then installed it all one detent off.
Then once the sprockets arrived I installed it again, one detent off.
On the final and successful assembly I found the 27 to 27.5MHz segment on the bandswitch.
I got real good at removing and installing the front face.

I admire your persistence and patience

:)

On a side note...

Your PC MINIPA board - I was hoping you didn't go too quickly to prototyping because as I went to look for your 50V withstand voltage, Voltage-regulators - they changed their pinot SOC design. To a 6 pin

A brief word about polishing . Heat is your enemy , oil and grease not far behind . When changing from coarse to finer compounds it's better to change the mop with it rather than mix grits . Although most modern auto wax and finish products will not turn color within reasonable temperatures a few will go blue or amber with just normal engine heat . To this day the only thing I've found for protecting the pipes is the oily rag ;-) .

And last but not least I made a final mop from circles cut from a chamois and stacked onto a a die grinder cut off wheel arbor . Too large a circle and the chamois just winds up on the shaft . Too small a circle and the die grinder easily over speeds the cloth and it disappears at extraordinary velocities .

So , I have these two identical appearing Cp die grinders . One was an experiment into "porting the rotary air motor" . The usual hog out the passages and not so subtly alter the port timing so that the torque went away and the RPM was somewhere north of 25K . The other is near stock save for it usually wears the 3" cut off due to its torque .

So I built up a 2 1/2" mop out of 5 or 6 layers and mistakenly stuck it in the 30K+ rpm die grinder ....

First trigger pull the mop exploded and for a instant I considered myself fortunate that the debris had somehow missed my face . I looked up to see a fair portion of the chamois wrap itself around a whip antenna and bend it near horizontal , directly away from me . In a near Warner Brothers cartoon moment I froze , the antenna froze , waiting for the inevitable .

What didn't hit me full in the face ricocheted off into the air compressor belt guard , there to foul and dismount the belt with enough force to blow the guard off . The rest knocked my last pack cigarettes off the the bench to be soaked by the last beer in the house also falling off bench .

it was worth telling

Reminds me of a story my dad told. He was 11 or 12, and got told to mix a gallon can of paint with a wooden stick. He had a better idea. His dad, my granddad had just bought an enormous Sears drill press. Dad reasoned that cutting a paddle from thin plywood that would just fit down into the gallon paint can would mix the paint more efficiently than the lame thin stirring stick. He cut the paddle, somehow fastened it to a metal dowel and chucked it into the drill press. Lowered the paddle into the can of paint and flipped the switch. Said it emptied the entire contents of the can in the first full turn or two of the paddle.

Lesson learned, he said. I inherited the pre-WW2 drill press. Weighs a ton. And yes, there are still yellow paint spatters visible on the blue factory paint.

i worked at a full line ihc dealer 1 year when i got out of high school. Worked in the clean up n detail department. We had an antique paint shaker.
1 day i parked a new ihc pickup by the room where the shaker was,went to get a couple things customer ordered extra for it. A parts man sold some old paint to somebody n he carried it to shaker,chucked it in n fired the shaker up. He didnt have can dead center in the holder groove,KABOOM can flys out the window all over new pickup. Red paint dont come off white paint good. Andd of course i was told to clean it off. By now its set up. I bufed 2 hours n finally it went for repaint
 
Just as you get it cleaned up something takes you back down the road to hell lol. I can definitely relate.
