Thanks Greg. I'm in the UK and have been struggling to find DC gearbox motors with quoted RPM. They often just have ratios of the gear box which doesn't usually help.

Glad to help. Seems like the low RPM gearmotors are in the 4XX:1 or 5XX:1 ratios...

No Hankscraft motors on the bay without paying £26 postage

I'm going to keep the search up!

I know that the Hankscraft motors have been the motor of choice for the laser show business for many years, I too was using these with lumia kits as my standard motor. Since the low RPM Hankscraft motors are becoming rare as hen's teeth, I've started using the Servocity motors for all of my lumia - they are smaller, encased in all metal and work great.

These motors are from Hsiang Neng Motors, part number# HN-35GMB-1640Y(R). This is a 12VDC 1 RPM motor, as the .5 RPM were not available when I ordered a quantity of these direct. Shipping from China was expensive and I wasn't happy about how they were packed, but everything worked and these are the best that I have located to date.

A group buy is a great idea Greg. I'm being pretty impatient at the moment though as want to get something built within a couple of weeks.

Thank you for your offer of putting me in touch with your contact. If we decide to set up a group buy here, that would be very handy

In the photo of your lumia rig, is there a name for the type of mount you are using?

It's just a simple 'L' bracket. Andy_Con can probably machine you some up on his CNC mill

it is a complicated rig, but i could not be happier with the way it works.

Cheers Jem. Yes, the smoothest and slowest I've seen so far are Swamidog's wheels which are belt driven. I was trying to avoid that as I don't have a workshop or many suitable tools - but where there's a will and all that.

Thanks Jem. I am so pleased this community exists - it is such a friendly, helpful and knowledgeable place. I hope I contribute someday too.
