POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

[ChazzC]

I remember having to "qualify" with one of those things. I think I actually put a couple of holes in the target. I didn't join the Navy to use guns. I was there to see the world. Saw an awful lot of ocean & some interesting places.

OT:

Qualified with a 1911 at an indoor range while at Newport (required a current qual in order to stand watches at Comm Officer’s School). Previously qualified with M16 & 1911 outside ranges at Little Creek; while on the 1911 range, watched a Marine Major shoot slow & rapid fire using a single action 45 revolver: all in the center ring (he had Rifle & Pistol Expert medals).

OT complete

(required a current qual in order to stand watches

That was the theoretical reason for having officers qualify. To stand deck watches while in port. The guns were in a locked cabinet behind the watch station. I only opened it once just to look see what was in there. There was a Marine stationed at the foot of the gangway with a rifle. Stiff as a board in his colorful dress uniform. Effective?? Considering the Japanese cab drivers could drive out onto the pier to take us into town, maybe not so much. Given how they drove I'm pretty sure they had wanted to be kamikaze pilots. Way more thrills than the rides at Disneyland.

Finished my rolling drill press stand. The drill press is too heavy to move without a hoist and I can see there’ll be times when I need to move it out to work on longer stuff. Plus it was too low.

Used a dolly I got in an auction lot (for $5!), added some wheel supports and a couple of new fixed casters, whole load of bracing using some c channel from another lot ($5!!), three welded on 1/2-13 nuts, some siding and it was done!
Before
Hoist extension came in very handy
All finished!

Turned out a little bit too high, but doable. Rolls pretty well but takes some effort to get going which is ideal

Even though an Ammunition Supply Ship, did not have a Marine Detachment (also didn’t get pier side in many ports ). In Port, Petty Officer of the Watch was armed, and we had a Response Team who were on alert status with shotguns & M16’s (had a false alarm and a 17 year old with a shotgun didn’t want to stand down even after I clearly identified myself as the Command Duty Officer - one of those days where they didn’t pay me enough). The CDO’s also carried 1911’s when pier side in non-U.S. ports (or non-military, like shipyards, such as the Key Highway Yard @mmcmdl ).

The Little Creek qualifications were part of our exposure to the Marine Corps: Marine officers are/were sourced from Midshipmen. The qualification at Newport was because the students at the Comm School provided security outside of working hours.

It involved plasma cutting and welding so shop time.

Nice, wish I was there. 14°F and snowing here!

That's what I thought when I seen his picture.
The only outside time for me was between the back door to the shop & back. I think it was 18 degrees here today, no snow, we got hit yesterday.

This is very strange. Is this an auto-darkening helmet?
My automatic welding helmet once "broke down" - and it also has photocells, but probably only as a fraud, because it stopped working.
The filter of this helmet was theoretically unassemblable, but not for me - I forcibly dismantled the filter cassette.
Inside I found two 3V 2032 lithium cells soldered into the board - both half-dead.
I replaced them with new ones and the helmet started working normally.

thanks for this, its the problem, BUT, in my haste I didnt take a note of which connection was pos or neg.
I'm hoping they are the same each side as I have one correct. I wonder if it will blow the control if one battery is the wrong way round??

But there are cells there, you must have missed them the first time

ATTENTION!

If you don't remember how the original was connected (that's bad) - don't rush, hold off on soldering the new cell!

If they are connected in parallel, a relatively large short circuit current will flow between them - AND IT MAY DAMAGE SOMETHING.

Tip 1. Take a multimeter (voltmeter) and check the polarity with it, measuring the voltage at the points where the original cell was connected.
If the "old" cell, which is still on the board, still shows some voltage, you should "see" it and at the same time it will indicate the polarity of the new cell connection.

Tip 2. Use a multimeter (ohmmeter) to check which end of the left cell (plus and minus) is in contact with the two solder pads of the removed cell - this will also show you the correct connection.

Tip 3. Check the board carefully (magnifying glass), there may be printed cell polarity markings there.

Tip 4. The yellow "cubes" are probably tantalum electrolytic capacitors - they have polarity (the stripe is plus); check which point their "+" ends are in contact with, you can check it with an ohmmeter too. This should also be the "plus" of the cell.

Your PCB looks very similar to mine - but it may be a different arrangement. In my case, the cells were connected in parallel.

If you were to solder wire to a regular 2032, do it very quickly using a good steel/nickel flux (acidic, e.q. ortophosphoric acid), regular rosin may not be suitable - first give small point tin on the cell, then solder wire (all with 60-100W soldering iron, this power allows for very quick soldering). All cells - especially miniature - do not like long heating to high temperatures.

Have you measured the voltage of the old cells 2032?
It's interesting what condition they are in. New ones - without load - may have 3,2 or even 3,3V.

PS: Sorry, I do not know the language well - I do not know if I am writing clearly

these cells were spot welded so I had to tear them off. I will place the new cells in with foam pressure pads to hold the on the terminals.
I had to cut a couple of lugs off the mounting frame to gain access and dismantle it all then lo and behold the batteries came into view.
Another case of a product designed with a very limited lifespan
