Flurries in August?

Big flurry of activity over the last week. The guys at VisionSteel have been busy with their day jobs, but put together the rest of the "bracketry" and the front battery box.

The picture on the left is the big picture. There are four batteries up front. My contribution to manufacturing so far has been to cut the plywood for the control board. It will reside over the motor. Clearance for contactors, fuses, and the controller should be a lot easier in this rear position. For the first pass, I'm using plywood. once the layout is proven out, I'll probably go with a plastic board, similar to a chopping block.

It's tricky to get the batteries in here, but we came up with a combo layout:

• two upright on the bottom, tall & narrow


• two sideways on top, flat and wide.

This picture shows how the front box fits in, just behind the AC evaporator. There's still good clearance between the batteries and the ODE shaft where the belt driving the AC Compressor will spin.

Here's where we put the aux pumps. The 12V vacuum pump (replacing manifold vacuum) for the brakes is on the left toward the rear. The Power Steering pump, also 12V, on the right, just over the steering box. It was salvaged off a 2002ish Toyota MR2 and has the reservoir built right onto the pump unit. Additionally, this unit has a speed input so that the boost varies inversely to the speed.

I've finally ordered the cabling/lugs & connectors. I did pick up some 3/4" flex conduit to run from the rear battery box to the front. That was interesting. I stopped by the electrical section of the local Lowe's, priced the fancy purpose built UL conduit, and went on thinking that I'd wind up with normal clear vinyl tubing. On to the plumbing section to price the normal household tubing, and it was twice as much! So, I'll have the robust, UL listed stuff like I wanted. Schweet.

It's been great working with James, Dave, (and now William) at VisionSteel. They've really tried to make sure that the structural parts are robust, but haven't lost sight of the craftsmanship. Go back to the May 10th post, and check out the picture of the rear battery box. Even though these batteries aren't wet, I still wanted to minimize the chance of battery stuff coming forward in the event of a rear-ender. After all, that's where the cuties ride. We'd discussed putting a plate across the front of the box, just behind the rear seatbacks. Check out the picture below of the flashy cover they came up with to address the issue:

So, Progress Continues, if slowly.

Reunited

Big progress today. The driveline is back in the car. James whipped up the "beam" to attach the motor clamp to the motor mounts. Badda bing badda boom and it's back in.

Now we can find homes for all the other pumps (vacuum, power steering), get the AC compressor back on a belt off the ODE and locate a couple more batteries. There's a lot of room left over up here since we crammed 8 batteries in the back, and will put two more under the rear seat. We only need to squeeze two under the "bonnet". Since they're AGMs, I can mount them sideways or on end. I suspect that the control board will now wind up above the motor. This will make for a layout curiously similar to EVAmerica's S10 examples. It will also make "Show and Tell" easier. We'll put the control board on a hinge so that it can swing up to show the motor while the batteries stay put between the AC Condenser and the motor.

Here you can see the two arches bridging between the clamp around the motor and sleeves around the existing motor mount bolts. The next shot shows the mount...mounting.

Now I'll have to remember how the Google SketchUp works so that I can adjust my 3D model.
Before too long, I'll have to get serious about my wiring diagrams. I'll also have to clean out the third bay of the garage again so that I can set up my electric shop.



Very exciting!

Fab Fab Work

Making headway on the fabrication of adapter, mounts etc. I spent some time down at the shop yesterday and took some pics of the progress. James has finished the adapter and has the motor & trans hooked up. We'll get it back into the car in the next few days and figure out what the motor mounts need to look like.

James has also fixed up the rear battery box. Here's a picture of it, loaded with four of the odysseys and a dummy Trojan AGM we were using before the odysseys arrived. My battery supplier loaned that Trojan case to us. The guys at the shop have had tons of fun tossing it back and forth in front of visitors...pretty impressive to be playing catch with something that looks like it ought to weigh 80lbs.

The real laugh comes when they toss it to the guest. Anyway, the battery box looks great. He got four down low, then four more right on top of the axle at trunk level. We were poking around yesterday, and there will be enough room under the rear seat, where the gas tank lobes were, for two more, so we'll have two in the front, with lots of leftover room for pumps and switchgear.

While I was at the shop, we...well, James, whipped up the clamp for the motor. I actually got to try my hand at MIG welding. Of course, I could only do a couple of lines on the bottom of the clamp; he didn't want my dribbly bead left visible after the whole thing's assembled.
