Do you have a link for the stand, it could be easier if i stuff up.

I've had an idea, i'll weld or braze a small 1 inch long square bar to the back of the bracket, this will push into the hollow arm of the stand then a bolt through it to keep in place, doing it this way makes it less likely i'll knacker the stand.

That stand is just a cheap one, an ebay search of lab stand will provide a better option.  I thought soldering the rod into a hole might be a little easier. I nearly made up the same set up as you, but for the same cost buying the one i posted earlier i thought not worth my effort. Then i made something much simpler,  my cost for it came to £25.

I posted this to some other thread earlier but here's that lab stirrer again connected to an Elma basket. My timer doesn't work but I wouldn't use it anyway. I also made a jar holder out of a wood plank.

Very quiet and very stable. These lab stirrers cost £85 inc. Shipping here in the UK delivery from Germany. I have even had offers from the seller for less than this. Coupled with the indian copy baskets , all in all a good cleaning solution for around £170. One tip i have, swap the round jars for square kilner jars, the fluid agitation is better.

@Neverenoughwatches Hi. Can you tell more about the basket? Looks like a Elma one, or am I mistaking? Thanks

Hi sorry yes i think you are right.

I might just do that if I found some tight sealing jars of perfect size. I'd still have to have some kind of lid that the rod goes through for some support. Maybe 3D printed if I had a printer.

I tried round and square, the square ones could really froth up the cleaner on a quick speed. I actually just leave the jars open at the moment until i make some wooden or cork lids.

out of curiosity what sort of speed are we talking about do we have an RPM speed for instance?

No sorry John,  slow medium and fast and lots inbetween. I use a basic voltage regulator with only a voltage input reading to adjust the speed of the drive motor.

Everything aside from the frame is on its way. The frame is the big mystery at the moment. I really like Gert's implementation, would be nice if the jars would also change automatically. The bad side is that it's quite chunky, I don't have that much space. The Kiwi Watch Cleaning machine project is a bit simpler and just works. The good part is that its smaller. 

At this point I started from the software, as I already have the components. I took a board that have Bluetooth and Wi-Fi... meaning you can get a notification when the job is done.  Maybe a bigger display would be nicer, will see... 

The plan is to keep the menu simple, just 3 functions that one could select by going up an down with the buttons. Probably I need one more button to act as a cancel/emergency cancel button, for when any of the jobs is running.

Sounds like its coming along just fine. A bit too fandangled for me I'm affraid , I'm not that tech savvy, an electric speed regulated drill and a Janta pearl basket is as far as my electronic knowledge permits me. But cant wait to see the finished version

A bit of progress. Got the motor to run. Speed, oscillation timers can be set, but in code for now. Need to combine the menu and buttons with the hardware that actually does something. Frame still is a big question.

I use the jars below and they are compatible with the Elma and Pearl baskets - just make sure you get the wide mouth version, its a little bit of a tight fit to get them into the jar, but there is more than enough clearance so not a problem. I also made some wave breakers from strip stainless steel which do a great job in causing turbulent flow, see link to thread below. Finally I use the red pressure caps to get a good seal, I found that any evaporated/condensed or splashed cleaning solution would dissolve the glue holding the cork seals in place and they would eventually give up. The read bungs work great and are very cheap.

Looking for advice. As mentioned in the video (forgive me for my poor English) there are 3 cycles/programs. Now the thing which I'm struggling with, is the time each program should run. How long should the wash, rinse programs be? 
 

P.S.: For anyone who is interested.
 The "Wash" cycle runs 200rpm forward and backwards, then the speed goes up to 500prm for a short period of time, aka different agitation levels. 
 The "Rinse" is 800prm, to directions, w/o any agitation levels (configurable).

Would be nice to add a "Spin" cycle at the end of every program, to get rid of the liquids in the basket. But this probably for the times if or when the motor could be raised up from the water.

Dry is still work in progress. I would imagine, the amount or rotations doesn't matter much? Maybe keep them low and just blow dry warm air?

 

Let me know what you think. Thank you
