some of the frames where made a tad thinner than others
when I installed my Dave Taylor I had to cut a piece of beer can sidewall and use it as a shim between the upper frame and the Dave Taylor so to fully tighten
without any wobble, you may have to do something similar

I had to shim my Dave Taylor head steady too. I needed some shim material and luckily I had a cold can of Abbot Ale in the fridge.
Didn't take much for a tight fit. The DTHS is nicely made. Maybe the Italian made frames have slightly larger brace tube?
Anyway, It really tightened-up the handling, and the ale was pretty good too.

Norton Commando (and Featherbed) frames were made by The Reynolds Tube Co. until around mid-1973 when the Norton factory began buying their Commando frames from Verlicchi in Italy (because they were cheaper than Reynolds).fiatfan said:
The Italian-manufactured frames are supposedly the ones with the non-matching "F1xxxxx" serial numbers and made with metric (60mm & 25mm) instead of (2.1/4" & 1") Imperial tube.

Just to throw a spanner into the works, I fitted a DT head steady to my MkIIA (F prefix) and had the same issue with the clamp.
I measured the bore with the clamp assembled and it was 25.4mm, so some material needed to come off one half.
I put it down to a process error - otherwise a very fine product.
I measured my frame tube: It was also 25.4mm. As far as I'm aware the 'metric frame' story remains just a story.
Why wouldn't they make their frames to the Norton drawing anyway?
The Ducati frames being made at the same time (pre '76) used UNF threads - not sure if Verlicchi made them, but their drawing was done by someone called Seeley
Abbot ale gets my vote too

I would expect 750 frames to be "58mm" and there have been reports of other 850 'F' frames with what appears to be 2 1/4" spine tubes, however, as you have found out for yourself, not all are.

The '1 inch' tubing on my MkIII non-F frame is around 25.7mm on average including paint, and the Taylor head steady clamped the tube without any need to shim, or rub down the clamp faces. The spine tube measures between 57-58mm (so 2 1/4").

I'll be moving the D.T. unit from my 72 over to the new 76 MK111 shortly , so it's good to hear the clamp fits well to the small bracing tube. It fit nicely to the 72. Quality is remarkable.

Sorry to get off track a bit but I been looking at the design of the head steady that Matt sells (CNW) and I think I would go with that one. Only because it looks to have a better anchoring setup. Save the paint on the frame.
Now, if only the Aussie $ would pick up again

Well engineered, low production CNC parts are never cheap. Sure I have something that basically does the same as the CNW part but it looks handmade because it is. My only saving grace is that it's hidden under the tank.
