Sierra Steering Column - drilling hole / hollow?
Hi, has anyone got an experience with the Sierra steering columns in terms of drilling through the steering wheel end?
I'm wondering about feeding a wire down though the shaft and then out the side to be able to connect it up to the loom for steering wheel
buttons etc.
I would be looking to cut the threaded end off to weld a quick release spline on so it will be machined either way.
Cheers

You may be better fitting a slip ring, if you have space?

Thanks but I'm looking at 10 plus wires and I didn't think you could get a slip ring for that, plus I'd like to lose the large
Sierra to 6 bolt steering wheel boss adapter. It blocks my view of the bottom of the dash.
I'd planned to cut down the column and machine the ignition barrel off such that the top of the outer column is cylindrical.

I might be pushing myself down the route of a brand new bespoke column....
This is what I was looking at:

Firstly the centre part of a solid rod adds little to strength so you are ok drilling it providing the hole is not too big, this is dome on land rover
half shafts if you wish to google. How large a hole you can safely drill is another question, you maybe better pff making a new column drom cds
tubing.
How will you prevent the wires from twisting where they come out? The movement will break them pretty quickly, plus wont they come out through the
uj?
Youd be better off using circumferential slip rings, cut narrow sections of copper pipe and epoxy onto the column, then spring loaded contacts. The
more accurate you can make it the better. There may be something off the shelf but expect it to be £££ as theyre normally precision stuff for high
rpm shafts.
Incidentally, radial slip rings have been made from concentric circular copper tracks on a pcb so very cheap but my gut feel is they wont last long.

A mate of mine did buttons on the wheel for indicators, flash, horn and push to talk for intercom/radio.
He mad his own electronics for flash rate etc then fitted using a spiral multi strand cable that plugged into the dash via one of those military type
round plugs.
This worked perfectly for many years and was a lot cheaper than that quick release.

Drilling Steering column
Hi.
I think that drilling the column will effect the integrity of the column, how much would depend on the size of hole you drill.
As an alternative if you go over to the Electric section of the forum you will find a post for "Free wheel wireless steering wheel" It
comes with 4 or 8 buttons and all control gear.
This would seem to be a better option as you would get programable use on the buttons without having to buy all the extra electronics,Also would be
the ultimate imobiliser if used in conjunction with a removable steering wheel.
I have no conection with this outfit I just cane across it yesterday and thought that it deserves to be sucessful as it gives KIT cars the ability to
have street car controls.
Best of luck please post results if you decide to try.
