Harness Extension
Having a bit of an issue with my harness, the harness mounts are quite far back on the roll car (back supports), which means the shoulder straps are a
basically a bit short.
I've heard of a few people making an extension out of 5mm steel, i.e just bolting a long bit of steel on roll bar thats 10cm long that will
rotate on the bolt, and attaching the harness to that. Also a few people have mentioned that I could use a saloon harness as they are normally longer,
but that requires buying a new harness!
Is there a better solution? e.g a small length of harness with a connector that I can add on? Can't find anything of the sort by searching the
internet
Thanks again for any help/advice
I have no idea what I'm doing.

Hahahaha. The harness fits fine for me, as I have the seat all the way back, but anyone less than 6 foot isn't going to have a good fitting
harness!
I have no idea what I'm doing.

If the roll hoop is MSA standard, don't weld anything to it. It will be o.k to weld an extension to material welded to it but do not bolt it on.
You can then bolt the belts to it as it will be part of the frame and not an extension....You cannot join pieces of belt together and be MSA
compliant......

There's no reason you cant weld to an MSA compliant cage, providing it isn't removing material or weakening the structure.

If the main hoop is modified to anything other than the ROPS certificate it will fail scrutineering, However, you can weld to the structure inside it
. All the roll hoops that have had extensions welded on top are being failed and certainly don't drill into it.

You confusing Homologated cages with those built to the specs laid out in Part K. Its only Homologated cages that have certificates and cant be
modified, and they are few and far between. The only Locost that has one i'm aware of is the Procomp LA locost.

I mentioned all that because I am aware that owners of these car do take part in sprints and hill climbs, which are subject to BB rules. It would be a
shame if he did the mods and if and when he entered a meeting, or anyone else reading this thread, and found it wasn't acceptable........

In a Cessna 152 Aerobat, the harness is anchored to the airframe with Cable Extensions.
Can you use that concept/Idea?
