looking for ...dome drive wheels

[skybadger]

Hi

I'm building a dome drive for a Pulsar old type dome that drives on the inside edge of the internal lip. I made some alloy wheels and put a tread on them but still they are not quite grippy enough.

Can anyone point me at a source of rubber tyred wheel (solid or inflated) of about 65mm diameter that I can mount on a 6mm gear shaft?

The tyre needs to be quite grippy on a smoothish gfrp surface. They are being pressed on using springs in linear bushes butt only from one side . I can't use idlers due to the frame projections on the inside.

Cheers

Mike

Have you looked at the wheel / tyre combinations available for radio-controlled model racing cars?  Maybe something available there?

I'm using Banebots wheels to drive my (wooden) dome, the green tyred variety, very grippy.

Hi,

Will be doing this myself fairly soon with a newer Pulsar, so driving on the outside of the flange which does make life a lot easier!

I intend to glue T10 timing belting to the dome flange and drive this with a suitable pinion. I know of several other Pulsar domes that use this method with great success. The belting and pinions can be bought from beltingonline.com - there are other suppliers as well but these people have a good selection.

Regards, Hugh

Huw that's really helpful. Who sells them in the UK ?

Hi Hugh

I did that with my first dome!. Sold all the parts on though so no longer available. Since its on the inside lip I wasn't planning to do this though.

Cheers

I like the T10 belting product - my own design (never implemented for numerous reasons mainly time related!) was to utilise second hand Subaru Impreza cam belts (of which I had several as I change my Impreza belts very regularly ).

^{It wasn't cheap though- I recall about £100 for 24' of belt.}

Good question. Technobots have stopped selling them 'for commercial reasons'

Robotshop sell them, but they are in France I think.

Might be worth dropping a mail to Technobots, they might have some stock left

BTW Mike, my dome drive was based on yours anyway

Hi Horwig,

seems what goes around comes around !

in the end I have bought some options from robotics.com and (re) discovered skate wheels are just the right size. Need a 'stick' soft surface though.

cheers
