The things I've thought while reading will distract me for quite a while.I can think of one or two things which may temporarily interest me more.

I’ve been looking for a concrete saw, is it the time of year.
Did you find them from eBay or facebook, or some where else?
I didn't know about the wheel washer but i'll take a look . the drive side swap I did know about . It's very simple and clever it takes minutes to do in fact swapping the water feed probably takes longer have a look on YT you'll be impressed .When I've bought mine(k770 same as yours)I've done a research and the manual states you just need to flip the wheel washer upside to use either 20 or 25.4 mm bore wheels.
The manual also states it's possible to mount the wheel on the driving belt side to cut closer to the walls.
Cannot see how to be honest since it will spin the same direction and it would need a left hand screw which will not fit into the right hand threads.
Mines requires a new top end and a service kit .
I've attempted to get it started for almost an hour but nothing to do.
Compression passes through the rings and goes out from the carburettor.
It does produce a nice spark
Not sure about the decompression valve either since no matter what position it feels the same.
About the choke,I think something happens because if you pull the lever and eventually you put back in run position , you'll ear a click when you blip the throttle

eBay, I was bidding on two and one both of themI’ve been looking for a concrete saw, is it the time of year.

Stihl TS410 are probably the best for cheap parts availability, the exhausts seem to undo / snap bolts regularly.I’ve been looking for a concrete saw, is it the time of year.

40k is a bit low for a dental drill? they go much higher I believe, 200-400k for air turbines? No idea if this motor is intended to replace the air drills or different purpose.A dental motor!

The plan is to use it as a higher quality Dremel, or rather, a significantly cheaper Eneska micromotor. I've had this idea lingering for years and finally bitten the bullet, not sure if it'll actually work, I might end up putting it back on eBay in a few weeks.
I know it's a brushed DC motor, don't know the top speed or the voltage, though I assume 40,000 RPM at 24v. I also don't know what handpieces fit it, I've got a straight, 1:1 speed handpiece on the way but I'm basically just hoping it will fit. I need to find a decent foot pedal too, and make a controller to power it.
If there's any dentists on here who are more clued up about these things, please speak up!
As far as I can tell, there's two different types of dental drills, "Turbines" go up to the 400k rpm kind of range, but you also get ones with a motor and interchangeable geared handpiece. The motors (Either air or electric) seem to range from 25-50k rpm, and the handpieces can be 1:1, speed reducing or speed increasing, the highest I've seen is 1:5, so in theory you could have 200k rpm at the spindle.40k is a bit low for a dental drill? they go much higher I believe, 200-400k for air turbines?

The high speed handpieces have water jets to cool the burr, I assume they also cool the bearings/spindle so you'd get a very short service life if you ran it without the water.
Let’s see the bikes then .Full set of control cables for a BSA Super Rocket, a Norman Hyde fork brace for the Norvin, a B.44 outer timing cover for grafting a Triumph three-ball clutch lifter mechanism into....
Various spigot cutters, a Dickson S2/T2 toolholder, a useful chunk of Tufnol round bar, and a curved riffler-type double ended rasp....
Not so very shabby at all....
As observed previously, unless some kind soul might post the things up for me via WhatsApp, its not something that I'm going to fret about....Let’s see the bikes then .
