Hi Philip,
I'm just at the "trying to understand it all stage" at the moment whilst I wait for the plans to be delivered and make a start. I think you have a brilliant solution to using the wig wag "as is" and thank you for posting the pictures explaining it all. I intend to go the mobility scooter donor route and have been pondering ways to implement the wig wag idea. Does the "gear lever" have a gate or just rely on friction?
Your Toylander looks well finished with ali cappings, upholstery and mats and I especially like the rubber safety trim around the windscreen frame edges. I do hope you post some more pictures of your build.
Regards,
Dennis
