Topic: K1 to K0 gauge conversion, how to?

[Don R]

 I read that this can be done, I looked on the 750 faces page and I see the reproduction K0 housing back, dial faces and the plastic housings. Can it be as simple as ordering those parts and swapping the innards? 
 I have assembled a couple K0 lenses on the plastic housings and have never been able to duplicate the silver ring around the edge. The closest I got was a chrome paint pen used on the back side. Any tips for that?

Pretty much that, yeah.  You will need the K0 specific backs- the K1 has a lip for the chrome pinch ring that the K0 lacks.  You could probably grind it off, but for me just getting the backs was easier.

You'll need to figure out the light tubes (for the idiot lights) and deflectors (for the backlights), but apart from that they assemble right up.

Yes, he makes very nice parts, the K0 backing plates differ from K1.

I'm interested also in converting a k1 set to K0 or sandcast.

While I didn't do much of a how-to write up, I did do this conversion for my K1/K0 half and half bike in the project forum.  I took a couple in-progress photos and may have dropped a bit of information about what I did.  It's honestly pretty straightforward.

The only difference is that I started with K2 (or later) gauges, rather than with K1 gauges.  The K1s are probably easier than what I used- the odometer/trip meter on the K2 and later is a bit wider than the K0/K1s, so it interferes with the light tube for the blinker light.  I had to scallop mine in to clear the gears.  Proper K1 gauges probably won't have this problem.

Visually, what's the difference? Black vs blue background? I no longer have Wyatt's book and Google is being a git.

The sandcast gauges have plastic casing vs metal on later bikes. The drive mechanism has a different texture.

 I had a broken K0 plastic housing once and sawed the back off behind the flange for the gasket, I think it might have crimped onto a K1 back. I'll dig those parts out also.

 Edit: it appears the parts are around $275 plus shipping
