MOOT Workshop: 1935 Hamilton Prescott Watch Repair

You thought it would never happen: A new MOOT Workshop video is now up on the MOOT YouTube channel!

This 1935 Hamilton Prescott wristwatch is missing a crown, and may not run, let's see if we can get it back in working order again.

My 1935 Hamilton “Prescott.” It didn’t run when I got it. I had another 987-F movement that ran, but you couldn’t set the time. I replaced the broken part on that one, and transplanted it into this watch.

This is a 1935 Hamilton “Prescott.”

The watch on the right is not running, and is missing its crown. It looks like the dial has been refinished, and the hands do not appear to be original. The serial number of the movement dates to 1930, so even that might not be original.

The movement on the left is also not running, but it has its original dial, hands and crown, and its serial number dates it to the correct year - 1935!

Maybe we can end up with a mostly original, working watch out of these parts! Stay tuned…

Without that Z-80 Softcard installed, the Apple //e powers up. (With it in, the power supply clicks continuously.) I don’t plan on running CP/M necessarily, so I think we can do without it. Now we can check the machine out properly.

This weird little plastic thing, perched on the back edge of the power/amplifier board in the 1930 Brunswick radio used to be filled with an ancient capacitor. It was almost surely bad after over 90 years, so I scraped it out and replaced it with this tiny yellow modern capacitor of the same value, held in place with epoxy putty. There are at least six more similar ones in the radio to give the same treatment to.

Worked out how to make a decent look-alike for the old resistors in the 1930 Brunswick Model 15 radio. The replica is slightly bigger, and the leads are slightly thinner, but it maintains the character of the original. There’s a modern 1-watt 50K resistor inside.

Now I have to make several more of varying colors and values.

Some kitchen appliance candidates for future MOOT Workshop episodes: A 2000s Michael Graves Design blender, and 1950s Osterizer blender and Sunbeam Mixmaster (with meat grinder attachment).

Update: The Mixmaster is older than I originally thought. It could be as old as 1935!

I’m mystified by the numbering around the controls. Anybody got an idea why it would be labeled this way?

Apple IIe power supply from 1985, doesn’t seem to be working. Although none of the electrolytic capacitors are visibly bad, we will replace them as a first step and see what happens.

Typical day in the MOOT Workshop:

Me: This thing doesn’t look so bad.
Thing: I’m all full of ancient electrolytic capacitors and my tone and volume pots are frozen and won’t turn no matter how much contact cleaner you spray into them! You will have to replace the lot. Hahahaha!

Decal test: This is going to work well. (The big color print is a photo of the original.) For the real thing, I’ll be putting down a silver paint backing for the whole thing, gold behind the banner, and then the decal on top (with final artwork). Part of this test was to see how the red will look, since the ink is a bit transparent, and to try the decal paper, which is wonderful. And yes, I know it’s not centered. It’s a test!

A quick test at re-creating the artwork for the decal on the back of the Brunswick radio chassis. If I take a little more time and care with the final, the decal is going to be virtually indistinguishable from the original.
