First generation sold out quickly, please see here.

Now we have 2nd gen, changes:

1. 3 ball-bearing grooves instead of 1.

2. Larger ball-bearings and 1 set more.

3. Remove the redundunt locking ring.

4. Modified top plate to accept Rainbow.

5. 0.5mm larger in column diameter.

Result is a more stable and a bit lighter? column.

If you can send me RMB through Alipay or something, I will grant you a handsome discount.
There is a known case using wise.com through Alipay by one of the members here, and I successful received the money in CNY.

Now that is a thing of beauty! I've never seen anything quite like it. Deposit placed. 

 

edit: Well, except for beautiful version 1!

I don't understand "1 set more" (ball bearings)?

 

Are there 4 sets, three of which run in vertical grooves? Or does one groove have two sets of bearings?

It would be helpful for our planning how to attach our mounts if you can post here a drawing with dimensions of the detacheable head piece and its openings. Also, one can need more than one head piece to keep with different mounts. What would be the cost of an extra piece?

I understand now! 3 sets of 4 bearings in each of three grooves! Very nice! I was confused because I often hear of a single complete bearing spoken of as a "bearing set" (one "bearing set" containing inner and out races plus the rollers or balls).

 

This sounds like delicious overkill! A variable speed motordrive running on internal Li-ion batteries that could replace the crank handle would be an interesting mod. grin.gif

I like pure mechanical systems. They never go down as far as you don't.

I hear you but electromagnetism is pretty reliable! But, yeah, probably an unnecessary expense. I was just dreaming of mods while I wait. I'm pretty tall so if I'm going to share the view with a child it has to lower a long ways. Probably get a step platform too.

 

What is the production timing looking like? I need to upgrade my Gitzo 3 Series tripod to a 5 series (and make sure I have the needed adapters) so it would be helpful to have an approximate date of availability. Just a rough idea, because I have no idea what kind of schedule this might be on.

CNC the parts.
Factory are experiencing power shortage these days.
So expecting some delay.

I've heard about the power shortages in the area, it must be difficult. 

 

Please keep us updated.
