Ideas for wiring loom securing
harmchar - 28/3/20 at 06:18 PM

Hi fellow Locost(ers),
looking for some ideas on how to mount/secure my wiring loom on chassis 25mm square tubing without drilling and pop riveting a hundred holes. Read somewhere I can't use cable ties to secure on chassis rails.
Trying to rewire a Locost/Haynes roadster that had few dodgy bits by previous builder and had to cut off most of the heat shrink sleeving to trace wires. He had the loom cable tied to chassis.
What methods have you guys used?
Thanks in advance.

Spending a lot more time in garage now we are in lockdown. Might even get this thing finished this year!!!

I think you can use cable ties, but not mounted on simple stick on pedestales.
the old way to do it (triumph car manufacturing) involved small steel strips welded to the chassis, and on a good day would have tubing slipped over them, and folded over to secure the cable

I think that the previous poster is right and that cable ties are allowed. Would proper, metal, cable ties be thin enough to fit around the tube without spacing future body panels off?

Why don't you want to drill the chassis? It only needs to be around 30cm centres so defo not millions! I used 20mm conduit in Pclips to keep it even more safe and secure. Used M3 rivnuts to keep the holes small. Could smalled if you just used plane rivets.

Car Builder Solutions catalogue has some useful tips in it
You can use cable ties and the stay pads but the pads tend to fall off after a while

I've used the cable tie pads for the scuttle loom supplying dash. But I have glued them on after removing the sticky pad. I also remember reading posts on here saying it was acceptable to use them but not solely relying on the sticky pad. They need to have second method of retention, so pop rivet or rivnut and screw.
Thanks for the replies and pics. Will go check what CBS are saying now.

Thats just interpretation, the IVA manual merely states must be secure.

I have used double loop cable ties on mine. Not iva'd yet but they are a good secure method as you can tighten them around the chassis then use the second loop to hold the loom.

Brilliant find Family Guy. Didn't even know these were available. Pack of 100 ordered.
Cheers all.

Large washers, bent and welded onto the chassis. I’m sure I’ve seen that on here...

In the transmission tunnel I welded a step of 1.2mm steel with a series of holes pre drilled
