What to do when the motor in your uniroller base dies...

[munz6869]

I completely rely on my uniroller now, for processing everything b&w from 35mm up to 4x5"... so imagine my horror when the motor burnt out halfway through a couple of rolls!!

Not to worry - rather than try to find another 240VAC one, I've used some of the old bits with a shiny new 12V DC geared motor to create this:

I ran 5x 120 rolls of Delta 3200 with it earlier, and they were beautifully even...

Good Morning, Marc,

I've never had to deal with a motor base problem, but I did take a similar approach to yours when I once needed to process some mural-sized prints. Those upturned furniture casters come in very handy! My set-up wasn't motorized, but it worked well with an oversized drum.

Cool.

I love Frankensteined shit.

I would pull out a spare motor base picked up along the way - altho, my favorite is the Ilford, of which I only have one - quieter and seems to have fewer nooks and crannies to accumulate chemiocal drips. Your machine eliminates potential for those problems, plus I really like the feature to keep the drum from walking off.

Nice ... now you need to make it reverse itself automatically.

Marc - what sort of 12 volt motor did you use ?

 

[munz6869]

I think it was this one http://www.jaycar.com.au/Electromechanical-Components/Mechatronics/Motors-%26-Gearboxes/12V-DC-Reversible-Gearhead-Motors---36RPM/p/YG2734

I see you made a stop at the Bunnings just up the road

Most of the things that are really important to me in my workshop (not photo stuff), if they are discontinued or hard to find, I have bought doubles of. If I relied on a roller base, I'd have two of them already.

I rely heavily on these motor bases so I picked up 2 more off ebay.

Awesome, congrats.

Don't you love it! A 6 year old post gets answered withing a couple hours! What a great community -- I need to pay up...late as usual!

I have two motor bases, one as a back-up, but I guess I could have two 3005 Expert Drums going at once! It would look pretty awesome!

I had a homemade one for awhile (someone else's home), but it made me sea-sick just looking at it wobble!

I have one for sale if anyone needs..$25 plus shippin

Replacement geared motor

I think it was this one http://www.jaycar.com.au/Electromechanical-Components/Mechatronics/Motors-%26-Gearboxes/12V-DC-Reversible-Gearhead-Motors---36RPM/p/YG2734

Marc!

Thanks, that's great. I have home=made dish rocking platforms, so that i can drink coffee as I watch the images appear. If interested, See my previous posts "Motorised Dish Rockers" and "Rocking Platforms". I had wondered where I would get a replacement geared motor - now I know. My present motors - now 20 + years old - rotate at 29 rpm, just right for sloshing the dev/fix back and forth with a 2 inch rise and fall of the platform. 36 rpm is not so different and I guess if it's not quite right I can reduce the rise a bit.

Looked at the video. Cute. For film I would be concerned about too much agitation, especially in 35mm as constant agitation can cause acceleration of developer through the sprocket holes and subsequent over development of the emulsion near the sprocket holes.

I have a Uniroller which I think still works if you're interested.

Thanks Dave - since the original post, nearly 7 years ago, I've progressed to a Jobo CPE2, which gives me the added bonus of temperature control. If anything, the agitation with that thing is far greater, which I've found gives more even and consistent results, esp. with sheet film.

Marc!

Wise move!

Peter, do you still have the base avalable?

[paul ron]

now thats a great way to recycle cordless drill motors! i have a couple drills with dead batteries where the batteries cost more than a new drill.

love it!!!! thanks.
