Help with spline?

Hi guys; I??

the easiest way would be get the triumph spline machined into a bush that can be fitted to the model T and retained by a keyway or scotch keyed

The diameters are very close (amazingly so considering the 60 plus years gap in manufacturing), I'd need to fabricate a stepped adaptor and would still need a 3/4" by 48 broach to make the internal spline.

OK. I'll ask. WTF. ?

michelle322, Jul 21, 6:07pm
you use the triumph steering wheel as it already has the spline and make that into a stepped bush or sleeve to fit the T.

Agree with Michelle322 turn the T2000 steering boss in to a bush and shrink fit it into the ModelT wheel and grub screw it for extra security. Only require a lathe.

Thanks for the feedback guys but sadly the diameters are far to close for a stepped bush or sleeve to work; (unless I have access to a broach with the appropriate spline, - hence my original post).

yea,the T steering boss is quite small.How about turning the 2000 steering shaft splines down to a neat fit in the T hole and get a keyway cut in the side of the shaft to suit the original one in the T. have it machined a little shorter and use the 2000 nut to hold it together.

Thanks for the interest mate, almost enough meat there to do it (The T uses a square section key) but the obvious solution is to find someone with a 3/4" by 48 broach. Apparently it's a very common size in steering linkages.

LOL, it's such a long story about one car over 40 plus years, I probably need to start a blog about the project!

have you considered changing the column to suit the wheel

sr2, Jul 22, 1:09pm
That could be a possibility but a new column would still need the same sized spline at the bottom to fit the universal joint. (The triumph column has the same sized spline at both ends).

external splines are easier to make than internal

Southwards in Paraparaumu have an engineering shop attached to the museum. Perhaps they could help.
Ken Douglas (Automotion) in Levin does a bit of spline work.

Is it tapered as well.
Just curios - Haven't got an answer other than some of those Kiwi ones already mentioned.

Back when we could - probably would make a sleeve to fit the Trump shaft on one end, and the T shaft on the other.
Method of joining could have been a shrink fit, or grub screws.
Would still be working today too.

Edit; When I mentioned sleeve - that would probably be a full length shaft with a short piece of the originals in each end.

Try PG hydraulics in Andromeda cres East Tamaki Auckland I have had spline work done here before

Thanks for all the suggestions guys. I??
