Taper bearing cups
« on: August 28, 2014, 09:07:23 AM »
Is anyone interested in replacing the standard loose ball bearing headset with taper bearings?  I have a machinist in the US who's interested in the project, and a forum member already gave me a schematic he used to make some cups for himself which use the bearings from a Harley.

The only hesitation for me is getting the steering stem machined to accept the lower bearing...I'm not in the first world at the moment, and so I'm going to have to search for a machinist I can trust to get the tolerance right.

Let me know and we'll see what he wants to do.  I'll post this to Ace's forum as well.

I'm interested!  As I am not at ALL interested in giving Hitchcocks $200 for a set of bearings.

1-since I know he's open to it now, it is Robert Straghan who provided the schematic I have for this...all thanks to him!

2-I got a quote from a machinist for $100, which by US machine shop prices doesn't seem too shabby.  That's for an initial unit--any others drive down the price.

I'm looking for a local machinist who can get my stem turned down to accept the bearing before I move forward.  Anyone else interested?

I wanna look at the pretty bearings, but all I see is Uncle Willy!

Seriously, those look nice.  Are you saying that the the steering framework will need machining to install them?

Steering stem base needs to be turned down to a few thou over an inch to get an interference fit w the bearing.  Stem itself is an inch but it flares at the bottom to accept the lower ball race of the stock headset.
