Well, here's a story. Bought a '68 2 door to convert to electric drive, hence the posting in this section. Nothing to do with Jonathan being most active here, honest ':)'. It turned out to be something of a lemon dressed as a peach, so a year later (after daily 10 minute de-scunging sessions), I'm getting onto repairing the thing. 2 new chassis rails, cross member, sills, spring hangers blah blah blah. All a bit new and scary, but at least it keeps me away from X-factor and the like.

I have a couple of questions and I'll post some pictures soon, in what will turn into more of a saga than a topic.

If I'm replacing 2 chassis legs, sills AND the x-member, what should I do first - I'm assuming legs, then maybe sill, then cut out what's left of the x-member and do this.
Why are parts from some suppliers about half the price of others? I'm assuming that you get what you pay for and just spent £500 with ESM (will I get a solid x-member, or the 2-sheet-original-bodge-job?) as my 'local' supplier is offering what seem to be el-cheapo variants :)

I have tools, but no experience. Nice 180 amp MIG borrowed from a mate, but not really welded before. Plasma cutter - partly because I'm a tool lover, partly to minimise the use of angle grinders. Also compressor, which is proving to be a wonderful thing. All I need now is some practice. This started by welding up a car rotation jig, which I know someone will have something to say about.<br>Image<br>

And here's an underside summary. Note that it's four pictures in one, the body isn't THAT bad!<br>Image<br>

Andy,

This thread may be useful as it covers the 'order of restoration': http://www.morrisminoroc.co.uk/index.ph ... estoration

Yes. Parts quality does vary greatly and you'll see that items such as wings etc are available as 'genuine' or 'pattern' parts. The pattern parts generally work out as a false economy due to problems in making them fit properly. Good luck with the project and you've come to the right place for advice :D

By the way, if you click on the 'preview' button after loading a photo you can load several photos onto one post.

What sort of running gear and controller are you planning? I am keen to convert mine when I can afford it ;) and am interested in what setup you will be using. Once done, I thought I would call it BatMog :) (Battery Morris)

Looks like an exciting project. I saw a Beetle at Santa Pod a while back which ran two electric motors on each back wheel, which removed the need for a gearbox. It ran very quick 1/4 miles.
Some folk try to use the Minor box prop and axle, all very weighty items and not really required.
Have a look at the Audi R8, the electric version, which has each wheel driven by individual motors, equivalent to about 400bhp and 1500lbs of torque.

I would think a fork lift motor directly driving the final drive flange would be the way to go. Lot of unsprung weight on the axle - but - it's not going to be going fast!

Hmmm, are you going to swap to electric instead of the Zetec Dan :D :D :wink:

No, I think I'll wait for the world's oil to run out first

Have you seen the Killacycle drag bike? 0-60 in 0.97 seconds and 158 mph at the end of the quarter mile.

Re-gen

Post by Julesgti »

Are you looking at re-gen?
That is using the deceleration of the car to either charge hydraulically or electrically to prolong the battery power available?
We have done alot of testing on both system and can increase the length of a battery charge.
Regards,
Jules :D

Hey, I thought I was the one that was supposed to ask the questions!

I was going to go all clever with the conversion (AC drive, Lithium batteries etc etc), but the remedial work has kind of slowed me down (£££ as well as time). I've not committed to anything yet, but the plan is 2 Permanent magnet motors (95 series, http://www.agnimotors.com/home/index.ph ... &Itemid=60) driven by a kelly(?) controller - this setup will do regen. The 2 motors go face to face with a (belt-drive) pulley between them and are mounted above the gearbox (so one of the motors is kind of in the battery tray and a pulley/custom backplate goes on the gear box. Bit Health Robinson perhaps, but I've looked at Jag IRS, trick rear suspensions etc so I can drive direct to the wheels or diff and it gets very complicated very quickly (unless I'm missing something). Also DC motors don't have quite the torque you need at low rpm (AC is much better for this), especially in hilly Bradford, unless you're a white zombie with 2 big motors.

As it's my first one & destined for the missus' runaround, I would rather have a slug that works than a rocket that doesn't. Don't care about batteries at the moment. The lovely boxer-engine bay gives lots of room up front compared with a eurobox & there's so much changing at the moment could be lead acid, could be firefly, could be LIPo with ultracapacitors, could be something not quite invented yet.

Yes, I know. It's pigeon steps here though. I might decide to space frame it and go all trick, but that's a little too daunting at the moment. Step 1 = MOT (ish).

Good news/progress and some more questions (should this topic be moved to the new restoration projects group, at least till I get past the point of rebuild?)

The first chassis rail fits, though the floor has to be cramped down by 1/4" at the front. At the rear, it seems like the replaced xmember end was put in a little wonky. The grey rod through the front suspension mount lines up almost perfectly and suggests that the nearside leg is a little twisted/s(h)agged. <br>Image<br><br>Image<br> Is this normal/OK?<br>

I am also having to mess about with the bulkhead xmember to chassis plate. This includes replacing some of the bulkhead xmember, which was like paper. This is an awkward bit, any advice?<br>Image<br><br>Image<br>
Am I OK to weld up in this position, or should the new plate be behind the xmember seam? Should I MIG/spot weld or seam weld this panel to the xmember? The inner plate of the xmember is pretty rusty, but this seems more like surface rust, so the dip-n-coat plan will hopefully deal with this issue.

The boxing between the bulkhead and engine bay is pretty rusty at the base (where it joins the chassis rail) - can I just cut small sections out and reweld/reconstruct the flanges, or should I be more radical here?<br>Image<br>
As far as order of rebuild goes, here's my plan:
1. dry fit (as above)
2. Repairs to existing panels (xmember, chassis leg boxing flanges
3. Drill out spot weld holes for MIG, clean all seams, spray with weldable zinc primer.
4. Weld it all up

Is this reasonable? I think I will get the car dipped and such, so I'm not so bothered about superficial rust/paint on the shell.

Finally, as a sign of things to come, here's some rust in the seam - above the rear wheel arch, below the rear window<br>Image<br>

Fun, fun fun! I'm feeling pretty positive at the moment, but I have had some bad days in the last couple of weeks (especially when looking xmembers!) It's only by reading this forum for the last year that I've summoned up the guts to do this restoration, so thanks to all of you.

These are great http://www.lmcltd.net/index.php?page=mo ... nerators-2

I built an electric ford escort van about 7 yrs ago with a pair of these motors on a common shaft in a dumbbell configuration , belt driven to the flywheel and clutch which were mounted on a stub axle/wheel brgs driving as std through the gearbox
120V with a fork lift controller

Very successful prototype , unfortunately the electronics expert who was building us the bespoke controller [ they weren't really available off the shelf ] couldn't come up with the goods .
We were going to try and get the Post office interested as delivery vehicles
It had the same performance as the diesel van and the range was adequate for an above average delivery round

Hi carlt,
yes, these LEMCO motors are, I believe, designed by Cedric Lynch who now works with agni motors. Lemco do a tandem configuration which could work well with a front engine rwd layout like a moggie, but I think the agni motors are a more up to date design - it would be great to be able to stack these motors rather than having to dumbbell them.
Nice idea to use a stub axle. How old was the escort, if it was rwd, surely it was a Mk 1 or 2?
If you're still looking for a controller, Kelly do a range that is well suited to PM motors.
