Quoted from Mbecker:
Thanks radius118 ! Cutting all the switches sounds better than desoldering.. hadn't considered that. I'll have to run by Tacoma screw as well, they are just down the street from work.
Looking at cleaners.. 22L good size? Can I get away with smaller? Looks like it has to be connected to water possibly ?
vid1900 -- totally fair, just feels weird to use kitchen stuff for things I'd normally do in the garage or a shop. I'm sure it's fine, but it's probably s good opportunity to get a cleaner
Like Vid, I re-purpose all kinds of stuff for general use. I used to have a stove in my shop for powdercoating too. I also used the stove top to boil out carburetors. Oh and heat up press-fit bearings so they went on with less effort. Etc, etc..
As for Tacoma screw, wait until you disassemble and have a good assortment of fasteners laid out. Then go to Tacoma screw and buy what you need in bulk. You might spend a couple hundred but it's worth it. Also make sure you get SEMS screws. These are the ones with the built in toothed lock washers. Used extensively in WPC-95 games. Also get LOTS of #8 and #6 stainless flat washers. I use them everywhere. Under SEMS fasteners to protect plastics, etc.. Put one on a post, put plastic protector, then plastic, then another washer, then nylok, etc...
Ultrasonic cleaners are like shops... You can get smaller.. until you wish you had gotten a bigger one...
I have 2 of these. I use one for pinball stuff and one in my automotive shop and they are worth every penny I spent for them: ebay.com link
You don't need a water supply for it and the machines aren't plumbed for it. The ball valve on the bigger units is for draining.
Depending on the level of filth on the parts, I either use plain water or 80/20 solution of water and simple green.... I usually use the simple green solution. There is one thing to watch out for. Do NOT leave parts in the cleaner longer than necessary. Certain zinc coatings can discolor if left too long. Especially that satin-y silver finish on some mech brackets, etc. You will have to experiment.
I usually turn the heater on to 60 degrees C and then run for 10 minutes and recheck. Also need to be careful with plastic parts - posts, etc.. Stainless can be run for as long as you want - doesn't hurt it one bit. I put every piece I possibly can in the ultrasonic unless it has art or decals on it. Even parts that are too big.. I will leave the lid off, do 1/2 of the part then flip it over. If you really want to see how awesome they are you can bring some dirty parts up to my place and I will demo my unit for you.
Vid is on the money for circuit boards. You can wash them in the dishwasher *without* soap without harming them. It is best practice to remove all socketed components before doing this, but you don't have to if you blow off with compressed air (wait.. didn't we have a discussion about air compressors? ) and allow to dry for several days in a warm place. But don't put any boards with relays in the dishwasher. Nightmare to get all the water out unless you pop the relay cover off.
Vid is also on the money concerning lead from coil dust. Don't even worry about it. You breathe worse stuff just following that Seattle Metro bus into work in the morning. Heck there is probably more lead in your drinking water than what you'll get off those wiring harnesses.
Same with micro switches. Don't immerse these in water or in the ultrasonic. But you're going to replace them all, right? right? BTW, buy these in bulk from Mouser or something. You can get 100 of them pretty cheap. No disrespect to our beloved pinball parts suppliers, as they've gotta make a profit and make their house payment too, but I'd rather buy 100 in bulk. While you are buying switches, add 250 1N4004 diodes to your order too. Switches are supposed to use 1N4001 and coils 1N4004, but you can use 4004 on switches with no issue. The only real difference between 1N4001-1N4007 is the amount of amperage the diode is rated for. They are otherwise interchangeable.
Another old school trick for wiring harnesses: Blech-white. Yeah, the stuff they use to clean whitewalls on tires. If you find that dishwashing and ultrasonic cleaning of the harness just isn't getting it as nice as you'd like, try some Blech-white. Spray and scrub with a brush. Wear dishwashing gloves. Now I've heard that the new Blech-white isn't as good as the old stuff, but I have no first hand experience with this since I still have several gallons of the old stuff stashed away. One day I will find out. I have also heard of using oven-off on wiring harnesses but I have never tried it.
Ok that's it for now.. I am way behind.. Got work to get finished!
