And very grateful I was too. I know you will be onto it Roo, but take great care when modifying the Speedo drive, particularly with centralising, alignment and countersunk screws. I presume you have read the notes in Aladdin’s Cave?
Oddjob:
Here's how I did it Roo.
Remove all parts of the dish the drive sits on, so it's totally flat, I ground most of it away and finished it off by using grinding paste on a piece of glass to ensure it was totally flat. Drill 2 x 3mm small holes in the flange of the dish, where you'd be expected to fit the screws. Next, fit the drive into the speedo drive and put that onto the spindle, fit the spindle into the wheel and press the speedo drive up against the wheel so that the flat part of the modified plate sits flush against the hub, keep pressing against the dish whilst removing the spindle and drive, care needed here to ensure it doesn't move. Mark through the holes with a felt tip so you know where to drill, drill and tap the holes, depending on space either 4 or 5mm. Tap holes and countersink the dish holes, fit with countersunk screws. Fit spindle and drive and test off the bike to ensure it a smooth run out. Doing it this way ensures the drive plate is central to the speedo drive. You may need to reduce the size of the dish to make sure it fits inside the disc, I had to do that so I presume you will to.

Yean phil, just had a recap but in all honesty I wont start anything until I have all the right kit. This was jaut the first 'kick in the pants' and i was only cleaning ;D Keeps my average up though, which is good ;D
I know Bryan mentioned to me before that there were errors in the wright up in the drop box and was going to bell him but was after the right bits after finding that cock up. I was awaer there was a differing way of doing this and after a yap tonight that should become apparent, we did speak about it a while ago and I really cant remember.
The 'flange' of a previous owner cut it out and then glued it back together. The piccie of it 'as removed' from the hub gives you no clue as to it being ruined. It was only after cleaning it and it falling apart that I 'twigged'that it had been got at by an absolute arse!.
Sesman:
I did it the second time exactly as Ken has written…..success.

Things moving on in the shed of dreams although this week has seen it renamed the shed of “really??!â€
After various discoveries from Bridgett I the past I’ve actually started to progress!
Frame is due back from the powder fosters on a week or so, got my rims back all sorted and the front hub has seen some action so cleaning fettling and generally grabbing fixings and replacement for shagged parts and the like. It’s going reasonably well even considering the new discoveries so can’t grumble too much.
The engine is about thete Barca few cover bits and a ball bearing and springfor the kick start but they should be here by the end of the week with any luck. Reasonably chuffed tbh.
Tank to ‘un-dent’ and solder up, liner to order and that can get dropped off for paint with the side panels and I’ll get cracking on the front wheel conversion.
Just sent the pipes off for chrome at a whopping £250 so I await them coming back to see how they look, they’re not the best set but the best I could find got what fish I had, we’ll see.
Thoroughly enjoying my time though which is what it’s all about
