Parts for dobsonian build

[Barv]

 

Hi all

Can anyone tell me please where I might buy truss tubes and fittings etc for building a dob? I've tried googling this but am struggling here in the UK. Most sites seem to be geared more for this in the US.

Thanks for any help given

David Lukehurst sells parts although he doesn’t specifically show truss components.

Barry Watts at Beacon Hill telescopes is worth a try, always helpful.

I got thin walled ali TV aerial masts from B&Q - quite cheaply

I use Aluminium warehouse. They are cheap. But make sure you select tube and not round bar.

If your on a budget or handy with your hands. make your own truss attachment.

This is tried and tested and works very well. Using a bicycle seat quick release clamp

These clamps are a great idea but you must put a plug of some sort (wood/ali) in the end of the tube because you could easily crush the tube end.

No dovetails?
