Today I acquired...........

because the sthil has a bigger bore and I don't have the correct spacer the husky is only 20mm bore . And I want a 350mm blade not a 300mm

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

I can think of one or two things which may temporarily interest me more.

The things I've thought while reading will distract me for quite a while.

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?

Yes ebay, FB or Marketplace. I have a Husky and maybe it's bad experience but it has always gave trouble. Hence my move to Stihl Con Saws now for my DIY use.

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 .

Mines from eBay bought used as spares and repairs

eBay, I was bidding on two and one both of them

Stihl TS410 are probably the best for cheap parts availability, the exhausts seem to undo / snap bolts regularly.
Husqvarna K760/770 good, also the old Makita petrol saws can be picked up cheap and parts still available.

3 lumps of delrin 205mm x 38mm, one may be a pulley and the other two could be useful one day.

A dental motor!

View attachment 440759

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!

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.

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.

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.

 

[Olderisbetter]

A dewalt bit box and 100 year anniversary drill, toolstation.. 10% off is you buy it early morning

 

[The_Yellow_Ardvark]

Many things.
A few I will keep, most going to new homes.

 

[The_Yellow_Ardvark]

There is more.

When we got home, a note was on my door.
"TYA, look in the trailer."

I did.

I was impressed.

A very heavy box.

But a Greenback helped.
Well he was with me unloading the other item from the car, see above.

I made up a drive shaft to measure the speed with my Smiths tacho, and found an XLR socket to power it from an old PC power supply, with the following results;

1000rpm at 5v
5000rpm at 12v
12000rpm at 24v

Not the nice linear volts to speed relationship I was expecting, but perhaps 5v is just too low to run it properly. Not as fast as I was expecting either, which makes me wonder if it should run at 48v. There's no part/model numbers on it so I haven't managed to find a datasheet yet.

 

[God mode restorations]

Today I acquired.
5/16 pre war whitworth bolts and half nuts. Plus I picked up the big vintage hand crank drill. No maker's name apart from 41 DML. Also some lovely old sharpening stones

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....
Don't do fretting....
