Mykk's BMW V8 T-bucket, version 1.5:

Did I mention Scatter Brained? Yeah, it's tough to focus on one piece at a time when you're on a parts hold for the existing projects in work and there is so much to do.

Today I decided to mock up the offset Euro stripe with painters tape. To keep the stripe on the grill the outer edge of the stripe should be roughly 8" from center. That 8" from center made for a stripe a little to centered on the tub. So I decided to experiment with a little forced perception, with intention of keeping the outer edge of the stripe 8" from center on the grill, 9" from center on the cowl and 10" from center on the rear while keeping the stripe straight. We'll see how it goes. I also learned I should use the laser for the vertical lines instead of measuring off center otherwise the stripes bow out with the shape of the tub.

The Bad Dad 905 tail light for baggers came in, they were willing to split up a pair for me and sell it individually. I'm really happy with the look.

Throwing another idea into the rear calipers & brackets. Volkswagen conversion (Ghia) calipers & adapter mount plates, modified and cut down to bolt to the jaguar stub axle flanges.





The minor offset between caliper mount bosses and flange face, I should be able to washer or shim the difference here.

 

[Mykk]

Looking at the side profile of the differential with the assembly resting on the brackets the pinion is kicked up while the arms are flat (XKE diff?).



I plan to mount the diff plate on the frame kicked up 5 degrees to 0 degree the pinion angle once mounted. Those arms will be angled towards the ground if I leave it this way. I'm not as concerned about the suspension travel angles as I am about the front radius arm pivots off the transmission crossmember lining up with the pivot angle of the arms on the differential.

I'm thinking of pulling the arms and brackets for now, and if the brackets won't angle differently after swapping left & right I'll need to source brackets that level the arms to the pinion (XJ6?)

Diff mount perch finally attached to the frame. Not fully welded yet; But it's on, it's lined up, it's angled.

 

[Mykk]

I've tentatively got the diff mount holes measured and scribed. Still need to mock the diff center section under the perch and verify that's where I want it before drilling through.



With the gussets in place it's become apparent how quickly I'll run out of room under that bench seat for all of the electronics and battery.

 

[Spanky]

You do nice work! Just curious . . . why are those gussets angled the way they are?

Thank you. In my mind it distributed any twisting loads across the entire surface area of the rear frame rail.

On bucket #1, when the rear ride height is lower the rear wheels negative camber inwards due to the axle vs the control arm lengths. I had this idea to use the axle spacers from the era when Jaguar moved the brakes outboard on their IRS. This should maintain the camber with a low suspension height.



With the spacer behind the rotors I can compensate for the space with the caliper mount brackets, and with these calipers it'll space the line fittings away from the diff cover where is otherwise would be a little tight. Although not necessary I am using hub centric wheel spacer rings inside the spacers to align the rotors.

Looking at the Tri-5 Belair 16:1 steering gear.

That is quite the input shaft:



Immediately tore it down to reverse it for the cowl steering:







Not completely finished yet, but I didn't have any ball bearings left over and it turns. 4 1/4 turns lock to lock

 

[Mykk]

With dowls in the brackets and the center section mock mounted on the perch, we can see that the downward angle of the control arm brackets will align the pivot points for the radius arms lower than the frame:



I'll be on the hunt for 0 degree XJ6 brackets.

Dont forget about the toe in adjustments for the IRS, should be around 1 to 1.5 degrees.

Thank you, I just recently saw alignment shims for in between the control arm bracket and the differential housing. I'll keep it in mind for the final steps of the project.

 

[Indycars]

Thanks for the great pics, words don't tell the whole story!

An awkward looking first one of two vertical tubes that will act as the steering gear and fuel tank mounting, not yet fully welded in nor the gussets added.

[LongJohn]

Damn Mykk! You may finish your second car before I finish mine! Lol

Todays Project:























I need to add another major mounting point to the box, which may mean welding a mount tab to the steering gear. I've never welded to cast before so we'll see how it goes.

 

[Mykk]

The XJ6 rear control arm brackets arrived and I'm excited to say it put the pivot point for the radius arms exact where I wanted them in the frame

Also making the rear suspension travel nice and even with the frame too. The metal dowel in the brackets is just to show to pivot line.

I wanted to see if an inexpensive 12v lawn & garden battery with 350cca would suffice to crank over this engine. Not only for the cost of the smaller battery but also the space saving. You can see I'm experimenting with the wrong size battery mount for it and I'm not completely sold yet.



As a test I hooked the lawn & garden battery up to the current Tbucket via jumper cables. It did crank and fire up the engine, but it was a slow cranking. In the long run the small battery might work because I was really putting it in the worst case scenario.
