Nice... that mount looks great!
Looks like you had to weld it to the frame... that's a little bit above my pay grade right now though. I am going to a machining shop tomorrow to see if I can have a mount custom made that I can drill into the swing arm.
Pardon my digression, but I made a couple of mistakes last time that I am trying desperately not to repeat.
The first is that I have to realize what I don't know. I am not a welder, I have no experience machining and I've got a lot to learn.
Since EV parts are expensive, I've got to factor this in with the fact that I've got classes to pay for and a mortgage payment. Really I am just scraping together what I have left at the end of the month and throwing it into a jar as a matter of speaking. In one year's time I am going to buy all of the parts from an EV supplier as a kit package. By that point, I want everything to just bolt in. I want my battery cage fabricated, the motor mount ready to go and a space for the controller secured. Really by then it should just be connect the dots. I have Bidwell's books "Secrets of El Ninja" and also "El Chopper ET." I have bolt patterns and ideas for where everything goes.
Lessons learned from the last time and mistakes that I don't want to repeat:
-I HATE brushless motors. Brushless motors seem to have VERY expensive controllers and also they seem to be temperamental. I'd set myself on fire before I'd consider buying a brushless motor again. If the wiring conditions don't pass all 365,000 of it's internal checks it won't close the contactor and then I've got no game.
-If at ALL possible don't buy ANYTHING from eBay. Most of the sellers that I've dealt with don't give a crap about customer support. They would have been more honest to replace the icon that says "Buy it Now" with "I've GOT YOU SUCKER!!!!" If it lands on eBay most of them seem to be concerned with offloading merchandise. I asked a simple question and one guy literally said "there's no monetary incentive for me to talk to you at all." If I'd bought the items from a retailer and it didn't work, I'd simply send it back. But here the guy clearly (and with a hint of rudeness) said "you're on your own kid."
-This kind of thing needs to be planned meticulously. It does not pass to secure parts piecemeal just because they look like a bargain at the time. "I found a deal on a controller, a contactor and a motor!"... great. But do they work together?
So essentially I've got a year to plan. But in a year's time (or less) I intend to click "buy it now" from electricmotorsport.com, cloudelectric.com, EVdrives.com or some other dealer and I do expect support from them. But again, by that time my frame will essentially be a "kit" and the parts will just bolt in to where they need to go. I'll wrap up wiring and then I hope to be 50MPH and gas free!
