David, you are now on the best part - the rebuild. Look forward to seeing the parts after cerakote'd....

So a u turn on the ceramic coating. Including some vapour blasting of carbs it was going to cost around £380 which added to the cost of £216 for powder coating the  frame is taking me deeper into loss territory for the restoration cost v final value. I have accepted that this is going to be the case but need to keep a sensible lid on costs when I can. I’m prioritising mechanicals over cosmetics and have just shelled out £104 for the last set of vesrah  gaskets from DS which sold out within minutes of coming back into stock !  Another reason is that ( and I don’t want to provoke controversy) my coater has been doing it for a number of years on race engines and says that he has found the only way to get a longterm durable result is to start with sand blasted surface not vapour blast. Really don’t want to do this with the lower case oilways and all some of which it is impossible to see down eg the drilling from oil filter to main cross bearing feed. So I’m having the cases acid dipped and will go down the tried and tested, worry free, rattlecan route. Anyone have an idea how many cans of the simoniz vht paint I need for the engine cases, barrels, ch ,sump and oil filter? Mist, light coat and heavy coat seems to be the way to go and not dissuading the missus from a weekend away when  I can use the oven ! ( have now bought 4 cans of paint for £27 which is more than okay and hopefully enough paint)

McCabe-Thiele (Ted):
2 cans or 3 if you are not polishing any cases.

Waiting for bits to come back I had a play with the speedo drive today. Managed to get it apart but had to resort to drilling out the grub screw to remove the shaft. Apparently if the two washers on the end of the shaft are corroded you can get wobbly needle syndrome which sounds embarrassing ! All back together at the second attempt having convinced myself one of the washers was missing only to discover over it had welded itself inside and was hiding down at the bottom of the drive shaft housing. Two washers changed the end float and it was sticky until sorted. All good now and a fun afternoon.

Now I’m confused. With the front wheel off the bike and spindle in place and spindle nut tightened up to the shoulder ( small spacer in end of bearing, speedo drive in place ) the spindle can slide in and out about half an inch.  Seems to me when the fork ends are attached clamping the spindle nut and spindle end the wheel can then move axially along the spindle and bounce between the disc pads. Is this how it’s designed - never seen a bike front wheel like this? It’s a like a spacer is missing but it came off like this and seems correct on the parts list. Thanks as always for the advice.
