I was initially thinking of using a hose clamp around the focuser. Might have to pay a visit to Bunnings.
How did you fix the mount to the hose clamp Martin ?
Thanks

Paul,
Once the custom aluminium bracket is cut and made it just slips under the hose clamp evenly
You have to fit the EAF focuser with coupling to the GSO focuser shaft at the correct spacing , I left a 4mm gap for movement
Once everything is in place with hose clamp tighten up on bracket , you can then drill 2 holes to secure EAF alloy bracket to your custom bracket
It’s a bit tricky but you will get the idea from the photos
I used a metal folder stationary clamp to hold things in together to mark the holes. All holes were drilled out on my workbench using a G clamp for accuracy
Below is more info and attached more photos
Custom bracket for ZWO EAF focuser
50mm high x 30mm width x 30mm long Alum extrusion. I had a 1m length in my shed I didn’t use for another project , otherwise you have to buy a length and cut a 30mm piece and have a lot left over
Cut one side and top
Mounting side where hose clamp holds bracket 18mm high
Outside to full height 50mm
Width obviously 30mm
Obviously depth is 30mm
Stainless steel hose clamp Bunnings
65 to 89mm
Black Electrical PVC tape
Run 2 or 3 rings of tape neatly around base of focuser to protect focuser from being scratched from hose clamp plus adds secure non slip clamping
Drill out EAF alloy coupling barrel
to suit GSO focuser shaft
Use the appropriate alloy coupling
Drill size is 4mm or 4.5mm ?? Check ?
Measure , drill out and screw EAF angle bracket to suit
Use 4mm stainless steel philips screws with nyloc nuts and washers
Cheers
Martin
