Hello! I just Completed a DIY Watch Cleaning Machine

[twincityson]

Hi Everyone,

Longtime lurker on this site but I'd like to get more involved in this community as I've built up a couple years worth of knowledge as an amateur watchmaker.  I love tools, which is one of the many reasons I'm attracted to watchmaking.  I looked around at trying to purchase a L&R machine but was put off by the price.  Last week I decided I could build something suitable for my needs.  Previously I've been using a 3 step ultrasonic setup.  I give you my Frankenstein!  Total cost of the build was approximately $150 (not including L&R #566 and #3 Rinse) and includes a heated dryer function which works wonderfully.  It took approximately four hours to design/assemble.  I used an overhead stirrer and threaded the attached rod to attach to a tea strainer.  And yes, those are indeed cones cut down to hold the mason jars :).  Looking forward to participating in this community.

Here are the parts:

VONOYA Electric Overhead Stirrer w/ timer and speed controller

Amazon Basics 500-Watt heater with tip sensor disabled (6x6)

6 inch HVAC connector

3 mason jars (thanks wifey)

Soccer cones (thanks kids)

Gladicier brand tea strainer w/ misc lock washer and nut from Hardware store

BN-Link Indoor Countdown Timer (for heater so I don't burn the house down)

Old shelving cut down (thanks house remodel)

Nice! Always interested to see others diy cleaner setups. The baskets seem to be one of the most difficult parts. 
does the motor spin/reverse, or one direction?

Looks  small foot print so good on bench top. The whole thing well thought out well done.

Thanks.  No reverse.  It'd be very simple to install a reverse switch but I'm not sure if it's worth it.  Just one more time I'd have to get up from my work haha.  Do you find you get better results if you alternate direction?

The problem with a simple design like this is the spinning creates a vortex in the fluid. When the liquid is rotated, a vortex will form and all the liquid in the basket gets spun out and the watch parts inside are actually dry. 

Baffles and a downwards propeller were added to break up the vortex, and keep the liquid in the basket. Reversing the motor direction will also break up the vortex.

Looks like you will have to get up and do a bit more work.

10-4 on the baffles. I can give that a shot if needed. The vortex is pretty mild and contained to an inch or so. Ran three projects through it so far and very happy with the results. Spotless under the microscope
