What thickness could I use here - aluminium

[tooth_dr]

Can anyone recommend a suitable thickness for the purpose of holding this hub between the rings?  I have some 10mm aluminium but that’s excessive I think 😂 

Thanks

Anything at all will be suitable. Heck, an offcut of 1.5mm would do the trick.

I was thinking of 2mm - readily available on ebay.  But yes, anything above a mm or so.

If you want to drill & tap it, for mounting the box, then I'd recommend 2.5 - 3.0 mm x 50mm wide (to aid rigidity)

from preference I use Carbon fibre plate 1 or 1.5mm. It also takes 3M VHB tape well. Use only small squares of VHB in the corners otherwise your box and plate become one forever........

I think you should stick with the 10mm,
you really do not want to under mount that heavy hub now 😂
or of course a 1-1.5mm bit would work very well

Thanks guys. I wasn’t sure, now I know 👍🏻
 

Ill get a piece 125 x 225mm to fit neatly between the flat areas.

Hi

If it's for a reflector, use the top rail to stabilise the tube. Then stick the hub with velco.

If you've got another dovetail bar,

just use it...
I was made to drill one extra hole in it.

Very nice looking setup there Roland.  thanks for the suggestion.  There is an engineering workshop a mile up the road, I'm picking up a piece later.

Mine are on 6mm, quite strong enough and thick enough should you need to tap hole in it.

Anything added in that position will need to be counterbalanced.
With extra counterweights or moving the weights further away.
It will also increase the moment and lower the system's resonant frequency.
Not many people know that.

I have used plywood and cable ties for holding stuff as power and usb hubs.

Thanks for the help. In the end I went for 4mm aluminium. It was the minimum thickness I felt happy with after seeing it in the flesh.

I didn’t bother countersinking bolts and just used surface mounted ones that I had, as the hub fitted perfectly between them!
