Well, I've paid and vehicles have begun moving, so, I'm committed now.
First post of a thread I usually like to keep updated as the project progresses so that someone can get the gist of the details without reading every post. I'll probably do that here.
-- Short summary --
Opel GT, mixture of 1969 and 1972, mostly 72. Rear defroster. Pop out windows. '69 rims. Engine and transmission are gone. Will link the thread later.
Not settled yet, but probably a 3-phase forklift motor I already have, got it for free spending a few nights pulling it off a Hyster carcass. More on that later. May repurpose an OEM EV driveline instead if it works out better.
Custom-built battery from recycled tool pack cells. Had a source of these for free, probably have enough collected now.
Not sure. A variety of choices, all costly. If I was using a DC motor I could use just about anything cheap, even just a starter battery to get it moving around, but a 3-phase AC motor means a fancy and expensive inverter to even make it rotate. May rig up a smaller DC motor just for testing and positioning.
Electric brake booster, otherwise stock brakes. Was given one from someone's aborted project. Will also have regenerative breaking from the motor if I go 3-phase.
Please feel free to ask questions about the electric part of the build process, but, don't worry about it. I have that covered and I have an EV community I'll ask for those details if I hit a wall. I'm sure I"ll be asking lots of car-related questions here though and would appreciate the community's help.
