Bockscar 3.0 Streamliner

[Stainless1]

Been cutting a few parts... the uprights I promissed and the bar the seatbelts will route over. I've built some floor braces not pictured... the plan is diagonals under the seat, from the seatbelt bar to the floor structure... the shoulder belts will bolt to the diagonals or possibly a bar between the diagonals, go over the pictured bar that is about  1-2 inches below the shoulders, and then over the driver to ensure he is pulled down against the seat. 
OK hard to visualize in this pic, but if you look at the laydown seatbelt picture in the book, they show something that is not really doable with a seat, but this will come close to my variation... the idea is to hold the driver in the seat with the shortest belts...  Nothing welded, I'll need to come up with what's welded first to make sure all can be accessed for welding.
That's what I'm working on now

  Can that crotch strap be moved under the seat a couple of inches or real close to the seat?

What is the completion target date for the 'liner?

Jerry, shooting for before you die... so don't try to rush me...   

Oh good....No need to wait " Til death do you start"

Stainless when you, get it off the Jig I may want to come borrow it  Sparky

John, no it can't... in a seven point lay down the cheek straps are the belts that keep you from sliding forward... the crotch strap actually is designed to keep your lap belt in place so you don't pull it too far up with the shoulder straps as well as a hold for the shoulder straps.  The belt guys would like the crotch strap to be a straight line from shoulder to attach point.  If you look at all the diagrams they show how a 7 point would look... all of them show the basic straight line. The crotch strap on the Bockscar attaches about 17 inches in front of your crotch.   Of course the seat is the floor with an elevated portion for your shoulders, your head is basically chin on chest and trying not to touch the padding behind or on the sides.  The liner seat will also be the floor...


Sparky, I'll work as fast as I can... whatcha building
I just read your post again... you want too borrow the liner or the Jig...

Well getting a few floor and seat pieces made.  The shoulder belt mounts and structure looks like it will work.  I will take it all back apart and get the 2 vertical tubes welded, then tack in the belt pieces, attach the seat and get my test subject (MC2032) back in the seat to make sure I have it all planned correctly.... then I can go back to work on the back half replacement.  Most of those parts are made and ready to weld, just had to get the cage finished before I weld myself into a corner that I don't fit into.  I just hope I'm not there already...

Your belts look a little thin.   
Wayno

[Stainless1]

And way too stretchy?  I did have the belts mounted to make sure the attachment bar was in the right place but stuff kept sliding out of position so no picture....
I did just finish a little of the welding on the 2 verticals for the cage but decided I needed to disassemble the back half to continue.... all that metal was getting in the way... and I cleaned everything off the jig that wasn't welded on so I should be able to rotate as required to weld

a new lakester/liner  frame

[Stainless1]

Been doing a little welding on the frame, unfortunately I can only do a little "out of position" welding before my body rebels.... The table helps, but I'm currently welding on the previously installed parts... that's the ones that were there but not completely welded in.  Filling gaps and holes as required while standing on your head sort of stuff...
You can tell you are in Kansas when you notice all the tubing gets a nice brown sheen and requires attention before you can weld... some off the car go to the sand blaster... on the car get the scotchbrite on the Dotco and the wire brush.

[Stainless1]

Made a few more pieces, did a little welding and tacked the belt attachments in.  I've built in some options I hope but I think my plan will work... Now comes the rest of the hard part, getting it all welded in.  I pre-welded some of the parts that I was sure were not accessible when it was all installed... Hoping the parts that are now tacked can be finished. 

As a sidebar, at lunch Tuesday one of my friends was talking about her Granddaughter getting scholarship offers all over the US but she was thinking she wanted to stay here for college because her boyfriend has a job here.  Then she said the boyfriend told her he could weld anywhere.... what's that?  he's a weldor?... Yes... you should bring them out to the house... oh and he's a bit of a gearhead... really, why haven't we talked about him coming out to see the race car?  Didn't think of it.... Well alrighty then...

So maybe my "out of position" welding will be getting easier...

[Stainless1]

Then Ross came out for a beer to talk about the new trailer project and see how things were going on the Liner.  So I had him jump in to see how things will fit... I think it will work, the belts will pull the shoulders down... just need to get the rest of belt mounts in and the seat cut for the new belt routing. 
Yes that helmet is just for fitting purposes... as you can see its been used once already.
OK back to making more floor and seat pieces... then welding and fitting... I'll get the cage mostly done then put the the back half back on.... well that's the plan

Nice! That looks almost as comfy as tucking in behind a tachometer on a naked bike

Hi Stainless
I looked at your seat belt setup and here are my thoughts for what they are worth. The general rule is the shoulder harnesses should be a minimum of 4" below the shoulders and should be as close to the back as practical. This keeps you from moving upward. And protects from neck vertebrae compression fractures. During Rocky's 2011 crash he came down right on top of the bike from about 6 - 7 feet above the ground at about 70 mph. I was right behind him and immediately worried about a compression fracture as his helmet only has about 1 inch of clearance on top. Within about 20 minutes after the crash he was totally black and blue from his shoulders to about 8 inches down his back but he had no neck pain. They obviously did their job. When I look at your setup it looks to me to not provide much protection from the helmet impacting the roll cage or from you moving back in the event the vehicle impacts on its tail. We use a 9 point harness but Rocky is in a much more upright position so I don't think it would be of much benefit in this case.
