I'm wondering if something like this might rock me to sleep at night? It would enable Jan to get a little extra sleep  ;D

I know they use something similar in the conservation department of some museums...

I also saw something like that in an old Popular Mechanics book...

Somehow, I find the power connections very "Wile E. Coyote" ... I'd be scared of touching the controls...

did that really just happen?  talk about over engineering. And the noise!  That would drown out my radio 4 afternoon play.

That's pretty much what this version would do...

The early ones I saw in the old Pop Mechanics were using vacuum powered windshield wiper motors with a faucet vacuum attachment... these were the really old days!

Somehow, I would have done things a lot differently to avoid putting unneeded stress on the motor.

Has it ever been created something to agitate the developing tank?

Well I suppose with Jobos and Drum rollers, it wouldn't be as 'original', sapata... although it would be nice to have something that did a more sporadic and gentle invert so that I could go eat cookies while making fantabulous negatives.  Everybody wins! :)

That's got "wet floor" and "possible electrocution risk" written all over it if I got involved.

Some people (speaking mainly for myself) are just better off using the manual version.  ;D

Well, there was also the Patterson Orbital Processor... which I tried imitating using an old record player. The wood disk has some rubber bumpers to keep the tank at an angle. The multiple holes are to prevent the tank from flying off the High quality "made in the UK" precision turntable...

I should add this was an early college build... ugly but working.

I never tried it for developing though... but it fixes good though.

Francois, you're brilliant!

Now, there must be a way of playing a record as well while the tank spins...  ;D

Not anymore... I ripped the arm off...
But it does dance like crazy when I put it on 78rpm :)
