steering arm taper converter
A bit of a mouthfull for a subject line I know but does anyone know where I can get a tapered pin that will fit in my (cortina upright) steering arm
that will allow me to use rosejoints mounted to the top of the arm rather than by balljoint below?
Hopefully that all makes some kind of sense  but in case it doesn't maybe the pic below will help (raldes product)
Alternatively what type of steel would this require to be made out of (en16?) and would it require to be heat hardened?
Cheers
Alex

They are in the rallydesign catalogue, on the page with the gts stuff on it.

If you mean the ones in the pic above they say "steering arm" in the product title but in the detail they say for the upright as a
replacement for the transit drag link 
And they are maybe a touch hicost for my locost pocket
Certainly the kind of thing I need, but they have to fit the steering arms rather than the upright

Okay, since this seems to be a dead end (unless I want to spend £120) would it be acceptable to simply drill the taper out of the steering arm fit a
hi tensile bolt through it and then attach the rose joint directly to the top of the arm?
It would mean using M14 rose joints for the steering (a touch overkill?) but would be a suitably locost solution to the problem.
Would this pass sva okay?
Comments appreciated before I get fed up and start drilling anyway 
Cheers
Alex

this might be a bit heavy duty, I think the shank size is 5/8 and the taper probably won't fit but they could maybe be adapted and are certainly
cheap enough!

i used a bolt direct through a rose and the steering arm. Worked fine. M14 is a bit large, thats why raceleda etc use converters and smaller roses
13mm bolt fits through without drilling the taper, 14mm would no remove it all anyway.

Somebody will probably slag this of, but it has worked. Fill the tapered hole with "JP Weld", let it set then drill out to size you
require, (say 10mm). Use a HT bolt with large, (penny), washers each side of the arm, fit your Rose joint and job done. All the JP Weld is doing is
filling in the taper. HTH Ray.

I would suggest drilling the taper out and then spacing down to a more convenient size if required. Ie, drill a 15mm hole and fit a 1mm thick tube to
bring it down to 13mm, or to a 1/2" bolt, whichever is most useful. That or use chippy's idea. Either way, make sure you use large enough
washers.

Thats more like it, thanks guys 
Interesting use of JPWeld (JB?) Chippy, I would have thought it would just breakup with the constant forces on it, but I suppose the big washers would
remove any concern over it causing a prob.
So either that or drill it out and sleeve it down to size, nice one, I was worried about drilling the arm, not sure why (maybe just one of those parts
i dont like to mess with) but if thats what everyone else does it'll do me too
Cheers

Hi Alex, reference your comment about the JB Weld, I used this to do a temporary repair on a boat prop, when damaged on a trip to the channel islands,
just as a get you home job, (big chunk out of one blade), That was over four years ago still using the same prop still going good. (bought a spare,
which is in the locker, unfitted).  Locost boating!! Think that should give some indication of just what the stuff will stand up to, after all you
can even thread it after curing. Regards, Ray

Lol...you have convinced me Ray
I've got a couple of M12 rosejoints coming (12mm bolt fits quite neat through the arm) so I'll give the JBweld a go to fill the taper and
with a couple of big washers either side for safety it should be just fine
Cheers
Alex
