Re: Prelude conversion project - some questions

All good - I'm sourcing a 13 mm thick bit of aluminium which can be tapped directly - less room for mis-alignment that way too.

I am assuming the problem is you drilled the holes for the bolt size so now you can't put a thread on it?
Bingo.

Nah, I have access to some machine tools today, I'll just make up a 13 mm thick block and tap it. That should be enough meat to keep it steady.

Re: Prelude conversion project - some questions

Sorry I wasn't clear in my post. My problem is there is no room for the nuts on the back. An alternative is to use countersunk bolts in the opposite direction but then I would have to assemble the midshaft-end plate unit as one, making repairs very difficult.

Re: Prelude conversion project - some questions

Haha, whoops. I got too excited, put my spacer plate in there, transfer-punched the centres and drilled them out. Went to bolt it all up and realised I don't actually have enough bolt poking out the other side, let alone room for a nut! So I will have to re-make this backing plate out of 10 mm steel...

Nissan Australia Leaf 1.0 battery replacement

Hi all, Elisa Millar from Nissan Australia called me to share this with our members - if your first Gen Leaf is showing signs of depleted range (SOH of 8 bars or less) it may be replaced with a new battery of 24 kWh for about $10k. You can't keep the old pack as part of the deal. *** Dear Capacity o...

Re: Prelude conversion project - some questions

Seems 4 mm is exactly the right amount of spacing required to get the shaft to sit at the right fore/aft neutral spot. I've found the same sweet spot for up and down too.

Re: Looking for unicorn droppings budget 6k

250 Wh/km is at the very bad end of the scale - more likely it will be around 200 Wh/km, affording about 100 km. Yeah, and these NMC cells are more sensitive to heat. One solution is to mount the cells on an aluminium cooling plate and pulling cooled cabin air across them in addition to what the coo...

Re: Leaf at Pickles auctions: 7 bars left

If a Leaf battery can be replaced for $9000 including GST and labour it's a pretty good deal. Even using prismatic NMC you're looking at about $12,000 in cells and easily a few thousand in labour.

I machined the edge nice and flat so the two parts bolted up square.

Next step is to add the spacer plate and mount the bearing to it. Going to have to use countersunk bolts with the nuts on the outside I think.

Re: Prelude conversion project - some questions

Hi Terry, The plan is to bolt this plate to the end of the motor, and then bolt the bearing support plate to the face plate. The exact position will be in the centre of movement of the mid shaft, with the spacing set accordingly. At this end it has about 5 mm of free play in all directions. Fortunat...

@jonescg I had no idea you could get copper cut so cheap. That's like 1/2 the price I could find on eBay just for the material! Who's your supplier?
Intracut here in Perth. Mind you, 1.8 c per mm means a part like this:

Re: Prelude conversion project - some questions

Well now at least the passenger side motor mount and mid shaft support plate are done. It needs about 5 mm of plate aluminium to space it out, or alternatively, a piece of 15 mm plate (preferred). Once this is together and the shaft is supported, we can drop it in the engine bay and mount the last t...

Normally a jet cutter charges for the time+material.
They should stock 3mm copper plate.
I actually find supply + cut cheaper than me supplying material. I get 2 mm copper cut up all the time - it works out to about 1.8 c per mm of cut.

Re: Zoe from sea level to 870metres and back

Agreed about the GOM's accuracy - I was counting the 5 km intervals as we approached each town and comparing that to the range remaining, and it more or less tracked it point for point. On a few occasions the GOM was pessimistic, but we'd gone up some slight inclines, only to recover those missing k...

Re: Zoe from sea level to 870metres and back

I only noticed the guess-o-meter when I went up Welshpool road in the Perth hills - I lost 20 km of range in about 6 km while gaining 240 m in altitude.
CanZE would no doubt be far more informative than the screen in the car.

Looks good - my only real issue with the Zoe was a need for DC fast charging. But an extra 10 kWh will help add a good 40 km of range on the highway.

Re: Small wind turbines

@acmotor has some experience I believe. I suspect the power ratings are somewhat arbitrary, as it literally depends on the wind. so 400 W might be a safe continuous rating? 1.5 kW peaks in gusts?

Re: Battery interconnect sizing

For the cables, I’m going to use 50mm² orange power cable. There's your answer. Aim to have the same amount of conductor throughout. If you use aluminium make sure the cross sectional area is at least twice as much. I'd use 2 mm x 20 mm copper at a minimum. As Brendan says, stacks of thinner stuff ...
