Steering worm and gear wheel

[Boston Lodge]

I am looking for a steering gear and worm wheel for an 8" scale Burrell tractor. I have looked at the dimensions of one for a 6" Savage and as the gear wheel is 3.687" across the teeth, it is possible I could adapt this. Has anyone got anything of similar size?
I am in fairly urgent need as I cannot steer my engine at the moment and the cost of having one made to the current specification is prohibitive.
Has anyone got anything out there that I can consider please?

Please see my reply to your previous thread. Without the information I requested I, or anybody else, cannot really help you.

Cheers
Carl.

Thanks for your reply Carl. The gear wheel is 2 1/2" across the teeth with a shaft size of 1 1/2" It has 25 teeth and the worm wheel turns 20 times for one complete revolution of the gear wheel ( not sure how you would work out the ratio). The worm wheel on the steering shaft is bored out 5/8" diameter There is room for a bigger gear wheel up to 3 1/2" and the centre could be machined to fit the shaft. I realise I am not going to get an exact match to the original but I am hoping that someone has something that could be adapted to fit.
