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?

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

      Hi guys. @VWatchie Those images are self hosted (not hosted on this server). Do a look at the page source and you will see this. I’m afraid, I can’t have control or backup images not hosted on this server. ( They seem to be served from here: https://qehvsw.bn.files.1drv.com/) This server is backed up fully every night and the database is backed up and versioned every hour, all stored off site on Amazon S1 platform. It’s hard for us to lose data. Ive got a huge overhead of space on this particular server the site is served from so no worries there 🙂 Sorry all for lack of response so far, I have been extremely busy and am embarrassed to say that priorities had to be set in place for a while.  Be assured that i’ve got constant monitoring and alerts should the site be in an extended problematic state (down etc) and work on these issues if they arise.

      Web sites are cheap. Message board are easy. Hosting both is less than 100 usd a year and small advertising would cover most of that.  In the discord group we did some 15 min poc and threw up a couple of different message boards on a domain i host.   The real value is the data / information / hive mind While I'm a rank amateur in watch repair the information and assistance on this board is invaluable. The members on here are friendly, entertaining and a wealth of knowledge This is what needs to be preserved  --Jeff

      HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....
