Hi all, I know one or two people on here have made their own rolling road style starters and I was wondering how they went about making them. Did you use a car starter motor or just any high torque motor/low torque with gearing?

For those who dont know they look like this...

Many thanks and karma cookies given as always.

Thanks,
Damon

Ariel Badger made his own and recently posted some pics and info on this site. I can't find the thread but it may be worthwhile PMing him.

Seen them made using an old minimoto too.

However, these days would go with some sort of electric - plenty of options available.

That's the plan, do you a 12v setup would be strong enough?

I've been sourcing parts all evening and have been given a fiesta starter motor for free. Not too sure It will be strong enough but for free it's worth a punt... if not, I'll buy something from a large diesel

Have emailed Ariel badger for some advice but have pretty much got everything together... My eBay "basket" is looking quite full. Thumbs Up

Reckon the Fiesta one should be ok.

12v setup is fine if you're going for a car starter - can get plenty strong enough.
Various other motors, such as those used in electric vehicles and you'd be better going for 36/48v ones as they tend to be higher power.

Remember a car starter will generally have a solenoid which engages it.

Fair play, this fiesta starter has the solenoid bolted to the side so it's all good. I will keep you guys updated on any progress. The RS500 is pretty close to being started now... Thumbs Up

Also, car starters tend to only have a bearing at one end (the other sits in the gearbox) this'll mean you have to make a bracket up (fairly accurately) with a bearing to hold the shaft steady. I'm pretty sure old fiesta ones are like this too but could be wrong.

edit: just read the Ariel's thread - exactly like he has done!

I've seen it done where people just make a pair of long rollers then put one of the driven van wheels on one side of them and the bike wheel on the other side.

No they don't. Most starters are completely self-contained units with no outboard support.

Well, all the ones I have knocking around are but they're all older vw ones. A quick ebay search suggests that fiesta starters should be self contained though so fair enough!

The 'outboard' support is in the cone/housing that surrounds the Bendix gear. Sometimes a needle roller sometimes cheap brass bush. But there is a bearing....

Let me know if you find it. Might be a bit better than the fiesta starter.
Thanks Damon

By 'outboard' I mean other than is contained within the unit, as opposed to relying on a gearbox bearing.

I guessed that but we demand 'clarity' @bcf Sir.... Wink

I think the home-made jobbies have that OEM outer bearing support removed and something else fabricated to carry the std. bearing.
