Hey Tommy...


I'm pretty convinced this car has lived it's whole life outside, and a lot of that parked over grass or dirt. there's really a lot of rust everywhere. I'll be able to clean up the control arms, differential housing, etc, but I'm absolutely going to have to sand blast a lot of it.

this is what the front suspension looks like currently.

the front subframe is pretty rusty on the ends, but doesn't appear to have been compromised. the middle section is pretty well oiled. ;-)

I was pleasantly surprised to find the main components in my totally rusted out MGB donor in good shape. Ugly, greasy, dirty, but cleaned up well. Mostly. Disassembly wasn't as difficult for me because most of the bolts were missing, i.e. pre-removed.

That's the crustiest front end I've seen on a Brit car. I wonder if it got driven in snow and slush when it was younger?

I had pretty good results derusting some crusty subaru control arms using electrolysis. Lots of videos on the Tubes of You.

Well, it's lived it's whole life in the northeast, so, yeah. Roadsalt too. It's pretty nasty, but salvageable.

My son was over Sunday for some yard help, and we also got in some Jaaag time.

The driveshaft came out.

I see a very simple expedient for shortening the driveshaft, simply by ditching the skinny back half, and moving the differential flange to the larger forward section. Both lengths are balanced from the factory, and I'd rather not disturb that if I don't have to. That will definitely get the engine behind the front axle.

We also did a hot compression check, and the numbers are great! The factory manual specs 135-140 PSI compression pressure at normal running temp. The numbers we saw ranged from 138 to 148, which indicates good cylinder sealing. When it started (it hadn't run since the weekend we brought it home) it ran rough a bit, and after it had warmed and I revved it up, it puffed a bit of blue out the pipes, but then that went away and didn't come back.

The good compression numbers, and the initial oiling out the exhaust says to me that the valves and rings are sealing really well, but there might be a bit of oil leakage past the valve guides/valve stem seals when its cold.

I'm pretty convinced there's no need to open this engine up, though I still need to determine oil pressure. The dashboard gage doesn't work currently, though it's pretty obviously got oil pressure, since it made it home from Springfield, and has put up with my hoofing it while it was warming up for the comp test. if its got good oil pressure, I'm definitely not opening it up. I'll set the valve clearance, check cam chain tension, clean it up, replace the leaky gaskets, and call this thing good.

And the chassis design proceeds apace. Again, it takes cues from the B-3, but there are some notable differences. Drivers sight line is 41 inches off the ground. it'll be low, but not crazy low. ;-)

I've had to take a bit of time away from the Pamilcar Jaaag Special (PJS) for the B-3 which needed another clutch refresh, but I've gotten a bit more done on the design itself, as seem below.

Long, low and lean. Rowwwr!

Looks really good, Robb, but I wonder if you might do something else with the windshield.

A Duvall type will match up with the rear better.

hey guys...

Nick, Rich, I just threw the original Pamilcar windscreen into the model to get an idea of what a windshield might look like, that won't be the final form. A Duval-style would look kewl, but it would make the wiper mechanism more complex than I want (having to wipe on two different planes) and I'm planning on re-using the XJ6 mechanism on this car.

TRX, take a look at Suffolk Motorcars. SS100 replicas are NOT cheap.

In other news, I have found out that the Jag XK 4.2 6-banger weighs in at 605 lbs, which is about what I expected. Its rather a lump. ;-) That's gonna make keeping to my sub-2000lb goal challenging.

JD, I AM the voices. #heresy4lyfe

Hi Rob
I've just spent several days working through the B-3 build - learned a lot and enjoyed a lot - whilst in the process of collecting my own bits together which, where I am, is proving less than straightforward. I've always intended a M/C engined 3-wheeler but of late I've been considering a V6/V8 4-wheel... so I'll be watching this build with great interest.
Good luck - MangPong.

Thanks mang!

Anyway...

So, whilst the XJ6 sits outside on the stands waiting for things to happen...

...one of the first tasks in this proj is to make space in the G'raj, because, well, there kind of isn't any.

yeah, yeah, yeah, I know, I built that shed...trust me, it's filling up nicely.

Anyway...

in order to apply some small level of logic to the task of clearing space, I measured the XJ, and determined that I'd need a space about 6 feet by 15 feet (which would fit the XJ6, but that's not going in there), and so whipped out the tape measure and a yellow construction crayon, and got to work.

Measuring from the base of the right-side wall out 6.5 feet, I marked it off in two places, and - after pushing the B-3 out of the way - used a laser level to mark off the line towards the back wall...

...and marked it off at 14 feet...cuz I didn't quite have 15 before hitting the wall, or getting rather closer than I was comfortable. Then I cleared stuff and swept the floor a bit...

...and, see all that stuff over there? That's all gotta go somewhere, not sure where, but it can't be there.

I'm planning on taking this Thursday off work to get the rest of the build space organized, and then start drawing some lines on the floor...

Build Table? Schmild Table...;-)

I've set myself the aggressive (I think) goal of having a roller in the G'raj by this coming September. it means, I believe, a summer-long thrash. My guitar teaching year is done the end of next week, and after that, I will need to be out there almost every day after work, and at least one weekend afternoon, about. 15-20 hours a week maybe?

its gonna be Gud Tymez, yo. ;-)

From tiny acorns, the might Oak doth grow, or, so I have heard.

Anyway...

These builds have fluid lives, growing and developing each in their own way, evolving from the Idea into the Thing. In that evolution, initial plans change, or are redirected to a more logical - or, really, less resistant - path, much like a river following the course of least resistance.

Thus...

I got back out to the G'raj, Thursday last, and began the process of clearing the right hand side to make the Jag Special build space, and of course had to push the B-3 outside. I then saw this...

The Three Amigos, right? Anyway, My Calibrated Eyeball (tm) determined that the XJ6 and B-3 would absolutely fit side by side, in the width defined by the G'raj door (161 inches in fact, cuz I measured) and so , Rather than having to find a place for all that stuff over there against the right wall, I could just clear a path down the side, that had the inner right hand edge of the G'raj door opening as its boundary. With that in mind, I measured and marked the door opening centerline...

Boring, right? But, now, Left side, B-3, Right Side, Pamilcar/Jag Special (PJS), each in its own space, and they fit...mostly.

Then began the very enjoyable process of laying out PJS chassis on the floor in bright yellow crayon. WITH LASERS! Dr. Evil approves this methodology.

Firstly, the drawing...
