How's Friday sound? New job is working 4-10's so now I can come over and bug you for a full day instead of just a few hours

B pillar hoop is done. Trying to get the main cage drawn up so that I can figure out upper link mounts on the chassis.






Shock travel lay out. 3.5" shock up front will give me 1.90" of vertical travel and a 4" rear shock will give 2.67" of travel if the shock is mounted at the innermost hole on a yeti trailing arm.

[Almighty Malach]

This is a pain in the ass right now, but it will definitely make building a lot easier.

Dang. Pulling out all the stops!

Cool stuff man!

I hope those plastic inboard lower link mounts hold up. Your first race will ask the question.

Jig time.

That why we need to make him some carbon ones!

Little more...




This is what I came up with to keep the subframe bars located. The two bars that go side to side are just there to hold the skidplate and lower bars from moving front to back. The skid plate can also be bolted down if needed.

Thank you. I am doing my part to try and inspire people to think outside the box; to show them that this hobby is way more than just ordering parts online and bolting them up.

Looks like the skid plate got more expensive... driveshaft clearance?

[SkaldidDog]

If the axles are 6061 just tig some link mounts to them and bypass the CF/epoxy gamble.

Yes.

My welder is a DC only machine, I don't quite trust the weld quality to hold. I would rather build new tubes out of 0.500" titanium

Casey, you ever consider doing a A to C bar rather than a B pillar hoop? Reason I bring it up is that I have come to like the smooth transition it gives you on the side of the car rather than the small snag points a B pillar can give you.

If there are subsequent versions of this design (or if this one takes many months) I should be able to help you down the road with AC/TIG of aluminum or titanium.

The last two cars I've built have been that way. I like it for that very reason, and I plan on building this one the same way. It's just easier to draw up a continuous B pillar hoop for the sake of seeing the lines of the car and making sure the dimensions work.

Thanks for the offer Joel. I will definitely keep that in mind since these cars will be a long term project.

I can understand doing things for the sake of easing the CAD work.

I love the jig idea, watching the full size builds using them over the years has made me want to do it myself. That's why I built my fixture table awhile back, but I want to go with a higher quality machined version soon that is actually drilled and tapped. Your tubing jigs will be fun to watch come together!

[Almighty Malach]

I have a couple chunks of 6061 that are 10" x 20" x .375" that I would love to have drilled and tapped for a table. 1/4-20 threads on 1" centers and 3mm holes in between. Then all of the jigs could be designed to bolt down and be interchangeable.

Someday haha




Rear upper link mounts.



All tied in.

[Szczerba]

Correct suspension geometry and adjustability?!?! No way. I need more bolt-on parts action.

The only thing bolt-on on this car will be the wheels and the body panels.







Shock, trailing arms and a rear mount mocked up. The shock is in the last hole in the mount because that is 90 degrees to the trailing arm at full compression. Moving the top of the shock forward will give a slightly more linear shock feel throughout the travel instead of the progressive ramp up at the rear hole. I don't believe I will need to adjust that, but I have a crap ton of those 5 hole tabs and I want to use them somewhere.
