I am with you Issac. Nicads when they get old just ain’t worth the trouble. If you charge them the may show voltage but won’t deliver amps.
Discard them them in ecologically safe manner.

📝 laser tachometer

I noticed on Amazon that you can purchase a touchless laser tachometer at very reasonable cost $20 USD. I have a box of motors that I have accumulated over the years that I would like to test and compare and I could see other applications for this so I thought I would give it try. For example you could test how fast a motor was with different battery voltages, or you could see how many rpms are lost when a motor is attached to a prop shaft in a stuffing box with prop.
I know this only tells you the unloaded rpm, not the torque or current draw under load. Still a nice piece of data to have.
Frankly, the gadget looked cheap and the reviews were not all positive, but for $20 I thought I'd try it anyhow. To make it work you attach a piece of reflective tape (included) to the object you want to determine the rpm of. If you do purchase one of these, note that you need some distance, around 1 foot from the rotating disk or it doesn't work too well .
To test the uninstalled motors I made up a brass disk about 2" in diameter, then soldered a collar with a grub screw to the center to secure it to the motor shaft. I painted it with just gray primer so I would be sure just the tape was the reflected part. It's easy to cut thin brass if you secure to a piece of wood with a little CA or double stick tape first then cut and separate it later.
Then I made up a little fixture where I could mount the motor. I added a switch, alligator clips and a battery connector.
The test was a success, the little tachometer consistently showed the rpm of the motors tested and I played around with it a little and worked OK in every case. I am sure it will be useful in the future

After all the calculations are done, nothing beats put the boat in the water and see how she goes. Then perform temperature evaluation by putting hand on motor.
Looking great to meeting

Coming along well, looking really good.
I never heard of of Jurmo class, (I never heard of a lot of things) so I looked it up. Quite an interesting subject, and unique choice for a model. Now that the steering wheel is in, its almost finished. 😁
I'll be looking forward to this build.👍👍👍

Oops, sorry didn’t mention soldering. Many of my fittings are made of brass and are soldered. Masts are generally brass so small parts can be attached with solder. Railings are soldered
Bet AI never heard of solder

My answer is…….I use everything. If there is no hurry, fresh clean wood, I use yellow waterproof carpenters glue. If I am joining unlike materials, wood to metal, for example it’s epoxy. Need to just stick a little piece on, CA. Occasionally to avoid squeeze-out on painted surface, I choose double-stick tape. Modern double-stick tape isn’t like the stuff you use for Christmas presents, a little piece holds like iron. Whatever is best for the job.
