MB750's MKIV Roadster build thread

[MB750]

Got the longer studs today. I tried installing them via a way the internet shows, by drawing them in thru a sleeve of some kind. Many used an old lug nut, but I had some 1/2"x20 nuts lying around from the build so I used one of them. I also anti-seized everything and gave it hell with my impact:



The two nuts between the washers are drilled out to 1/2".

Aaaaaaand the nut stripped at this point:




I love having a 20 Ton press in my garage. Made quick work of the rest:





Now I need either deep lug nuts, or cut 1/4" off the ends of those lugs. Since that end isn't threaded I'm gonna think about it.

It's been a while and I've done quite a bit since my last video so here's an update.

***Parental Advisory - Explicit Language***

Trunk struts done:




I fished some solid conductor thru a couple holes in the trunk so I could easily pull the wires thru.



This is where I cut the door panels to reduce the gaps. I'm waiting on the vinyl ester resin, which should come in today:



LED head lights too. Those incandescent ones from FFR draw almost 11A each when both filaments are on. These are 5.8A each.

I was also playing around with the latches and the striker. I made an offset for the striker so I could get the door fully closed.



But what I noticed is the striker just barely fits into the latch, so I ground down the latch where the striker falls into. Now there's a bit more play and it's smoother.

I also noticed FFR expects me to drive a few rivet nuts, and compassionately supplies a single 1/4"-20 bolt, nut, and fender washer to install it. Yea......... Looks like an opportunity to make a rivnut installer!



1/2"-13 left hand thread bolt and coupling nut. My mill drilled it out to 17/64" and Bob's your uncle.

Fun fact: I just discovered that if you put fiberglass under tension, then heat it up really hot with a heat gun (but don't melt it), and then let it cool, when you remove the shims it'll pretty much stay where is was previously being held.

[MB750]

Now I shouldn't need a few cubic yards of Bondo to smooth out the transitions.

Put this affair together:



And installed the passenger seat and lap belt:



Then me and the wife went for a spin! Just out around the neighborhood, 7 miles. All systems go, but I do have a little drip of antifreeze somewhere. I'll investigate that later. For now I had a great Saturday with the Cobra.

Nice work Matt. Are you still grinning?

It's been fun following along.


Cheers,

Nigel.

Thanks Nigel. Actually yes, occasionally my mind will go back to Saturday morning with my wife riding shotgun and the car running smoothly. It was a great Saturday.

Then again last night when I stepped into the garage to pull a beer out of the fridge. When I turned the light on and saw it just sitting there my mind pulled back to Saturday.

I think we're gonna have some memorable times going forward.

I made a charcoal canister out of PVC and some brass fittings. One end takes a 1/4" hose, the other is a cap with a bunch of small holes drilled in it, and the insides is packed full of charcoal bits that I bought from Petsmart that are intended to be used for fish tanks or something:

Here's some recent photos for levity's sake:

I just realized over the course of this build there's a few different motorcycles in the background.

This one I'll be keeping around for a while. I inherited it from my dad. It's a 2022 Heritage. My garage only has room for one and this is it.

Don't know if you did this, but putting some filter elements in either end will prevent the dust/small bits from falling out either end. I used some scotch brite pads cut to size.

I made that thing months ago, and I'm pretty sure I did something, but now I really should to take it apart and see what I did. Otherwise, I've got scotch brite material around here somewhere. That's a good idea.

I do know I crammed it in there and tamped it a bunch of times to really settle the charcoal. I also made it so tightening down the top cap the last 1/8" would compress the charcoal as well.

Steel wool:





I know it may rust in time, so I'll check it again at the break-in oil change (500 miles).
