M1078: un-build thread.

[olly hondro]

Plan is being executed for the roll cage fab, may as well share how stuff comes apart then goes back together.

A stripped out cab is en route to the fabricator (thank you, NV555). When the cage is finished, will swap the modified cab with mine.

No need for me to wonder what to do with my spare time.

**Update Dec 12, 2018** I am consolidating this thread with two others. The result will be here:

Did you consider creating an exterior cage?

Yes, I did consider an exocage. The Fabricator tells me that the vertical elements catch on rocks/ canyon walls. I see evidence of this in the Top Truck Challenge videos. A popular trail near here is Box Canyon at Florence AZ, so you get an idea:


With an internal cage the sheet metal smashes down against the cage then,well, the truck continues on with abit more character than before.

IMHO I would do both.. Internal cage with Exo roof edge rock sliders that attach to the inner cage via metal plates welded to each cage and sandwich/bolt thru the cab's skin.

I had not considered rock sliders at the roof line.

In some of those Top Truck Challenge videos, there are rigs that have small wheels mounted horizontally at the roof edge just for that purpose. I have not been impressed with those wheels in action, however.

Use blocks of nylon, low profile and easy to replace.

UHMW, not nylon...



I put upper sliders on my daily after taking out the LR quarter on a trail...

Ehhh, some polymer
