There might be more to it than meets the eye?
For example, what keeps the wire tight regardless of slip between the driving wheel and the quad wheel?

They are geared up so as there is a slight amount of reel slip but wire stays tight

Thanks @devonshire farmer I couldn't work out how it knew if the reel was full or empty ...........

The question i would like to ask is has anyone built one or anything like it as a workshop project? as i could do with something like it but baulk at the price of buying one.

Not quite the same but I made a bracket for the polaris for using with geared reels. Only used it once but managed to put out 400m of fencing without getting off my seat. When I take fence down I will have to wind in each reel individually tho. I felt I wasn't going to use a rappa system enough to justify the price too either.

Well I think you've had very poor service from rappa then, particularly as those machines are the best part of a grand!

I haven't had a very helpful response from them in the past.

So to hijack, but if you unwind a wire from a standing post, how to you stop the reel from locking into the post, rather than free wheeling?

@andybk made an electric motored setup I believe. On here somewhere.

Why would you unwind from a standing post?
Reels unwind from the bike.
Which is how I also do it if using geared reels.

A wiper motor (leave the gearbox on) from a car might do for the above application?
Could run it at 6Volts if to fast ........

not strong enough , 12v golf buggy motor is better , will pull 400m in a straight line ok

No, sorry I didn't explain fully, I haven't got a rappa machine, just the fencing set of reels and end posts.

I would put them on a shaft or something mounted on the bike.

Yes, I put a bit of pipe over the shaft to hold them of the lug. When i was in NZ we had the same type of system, but one side of the reel has notches and one was smooth, so you turned the reel around for unwinding. When I approached rappa about it they didn't seem interested.

Are you sure it's designed to be transported in that position. I have that rappa and it's a big heavy lump, being suspended from a single point at one side of the machine will be exerting a lot of force on that joint.
Transporting it propped up is not ideal either as this broke the rear rack mounting on my quad bike.
