Hi Tony,



I know that bikes and karts are starting to move to belt drives, and I'm guessing they may be around the sizes you mention. Might be worth looking in that area.

The electrical people?

thanks for the tips - smaller ally pulleys can be had but they are a rare beast and cost more



we've ended up going down a different route in the end - all will be revealed at claydon



cheers

Tony,



Just a thought, if your current setup proves to be two problematic, have you thought along the lines of utilising the second engine for a lift engine, and using one for thrust?



It may be that a twin setup of less than 250cc may be an alternative way forward. 30bhp thrust on a lift engined craft



I know the regs are against it for F3, but if proven to be matched to the TZr variants, could a dispensation ala rotax 447 could be allowed?



I wont be at claydon, http://hovercraft.org.uk/images/icons/smiley_icons/icon_sad.gif any clues?

Jonathan,



Yes, the electrical people. Get yourself a set of catlogues or go on line. I think you will be suprised at what they do!



Thay have pretty much everything you want, but at a price.

Yep, they've had to diversify to keep up with the others, Farnell (now Buck Hickman I think) etc. By the way don't order a set of catalogues, they are HUGE, they will take over your workshop (I think it was 6 catalogues to a set the last time I got some) and you will be receiving them 'til the day you die!! http://hovercraft.org.uk/images/icons/smiley_icons/icon_lol.gif



Look at Brammer, they don't only do belts and bearings now, they do a vast range of products for the workplace, including safety products (good for my business, and that makes me very happy http://hovercraft.org.uk/images/icons/smiley_icons/icon_biggrin.gif ).

farnell was taken over by CPC. They send you a nice hard backed catalogue!

Other way round. CPC were aquired by Premier Farnell the holding group for Farnell and a few other electronics conpanies worldwide.

Tony,

The supplier is said I might have is rather expensive.

The pulley would have to be made at a cost of around 80. http://hovercraft.org.uk/images/icons/smiley_icons/icon_eek.gif

I can get a steel one for around 9.



The supplier is Antifriction Components 01392 824343 if you decide to go down that route!



Best regards

An economic solution if you have access to a lathe could be to turn out the centre of the steel pulley and epoxy or press fit an alloy hub in place; how much power is being transmitted?

If I'm retreading old ground please don't shoot me, it's me first post!
