This is a non-profit exercise, not commercial. So I don't think it breaks any rules.
I have designed a RA Extender for the Gemini G11 mount which extends the RA axis by 2 3/8" (60mm) and uses the existing cap-screws to mount it. It has a circumferential groove 3/32" across half way up for the wire or card for an east heavy counterweight and key-hole slots to allow the insertion or removal of the wire or cord without removing the extender from the mount.
I've attached a 3D pdf file which I think will allow you most readily to visualise it:
RA Extender 2 3D.pdf
The LOW price is GBP45 per unit (say AUD87.50 or so) plus shipping from Kenilworth, England. To get this price I need to order 50 units.
I've already got 9 pre-orders . To get this manufactured, I need to get another 30 people (approximately) on board and once critical mass has been achieved, I will want payment in advance please.
If you are interested at that price please email
david.partridge@perdrix.co.uk with the subject "RA Extender 2":

and I will record your interest.
