Memmeddu, what is the diameter of the drive belt or better still the measured distance round both pulleys ?
Our Men's Shed is looking for a certain sized flat belt to put on an obsolete SIP planer / thicknesser we have been given . It is in tip top condition save for the missing belt that drives the thicknesser cutters

I've an old 770 belt in the garage I can measure up for you if you want . I've not long ago put a new belt on mine .

Sounds like a prototype Bki cooker . What type of fire extinguishers and stand by help do you have on hand?

I had a couple of friends watching (from far away behind cars lol) and combo of some foam fire extinguishers and co2 gas bottles for rapid oxygen removal without damaging it.

And of course if it all went tits up a rag to throw in the compressor end lol

I don't know right now but I can check tomorrow

I've actually watched the blade side switch and it's very easy.
I wouldn't imagine it was so simple

Practically completely disassembled the Husqvarna K770 Power cutter.
Yet to disassemble the crankshaft and engine block,but this isn't probably required cause it's just 3 years old, and the bearings seem fine , crank seals concern me little bit but the looks fine .
Cylinder is salvageable so I'll keep it ,piston is completely scrap.
I'm pretty confident that they ran this K770 on straight gasoline do to the fact the piston has melted on the top.
But could have been lean too but I didn't found any possible air leaks .
I'm not sure about the cause of the failure but the piston was bone dry no oil and even the pin was dry .
Bottom end is oily cause I've tried to start it using spray oil and brake cleaner ( it does work but had no success with this saw)
Anyways here's the thumbnail for the video which is actually uploading

Good job but the state of that piston, skirt and cracked the barrel is scrap too I'm afraid just get a top end kit for it.

I did weeks prior to disassembly because I already know that if there was something wrong it would surely be the top end

Let us all know what you get for it ££££££ etsy maybe Or what would you like it to achieve ...
does look good

My trouble is I want to make loads of random stuff, buy can never really be bothered trying to sell it. Usually end up going cheap.

That's a shame , I suppose a lot of people make good stuff and it's nice not to be a production line but I suppose this is where the etsy /insta self promotion IT nonsense has to step in . which to be honest is everything I'd want to stay away from .

Removed the wire harness from the engine bay in my punto.
Checked this morning.
Found out
Hit and miss continuity on the knock sensor wires
Hit and miss continuity on the crankshaft position sensor wire
No continuity at all between common ground from the ECU to every single fuel control system sensors (Crankshaft position sensor, camshaft position sensor, map sensor, TPS, idle motor ,lambdas )
I need a new harness ideally, but has a code which is hard to find there are similar ones which can fit but might have differences in the pin out positions on the ECU .
I don't think it's worth the effort to repair the one I have
But it still an option if I don't find the correct harness

Well, a totally chaotic day today, started three jobs and finished one
Thought I would start by getting that lump of steel in the mill and squaring it up:


It was well out, but it came right:





Then set my X and Y zero's:



Whilst going back and forth on the manual Mill I decided to set a job up in the lathe, I managed to get the collet chuck in before I remembered I needed the three jaw in:



abandoning this idea for a minute I decided to get a job set up in the little CNC, first up, some way of mounting the job. I decided to fasten the plate I would use to the sacrificial using countersunk screws:



This turned into a disaster, somewhere along the line the drilling program defaulted to 12.7 mm (Bobcad, known bug) and I am just learning so managed to put a mark of shame in the table, I watched it do it, mesmerised like a bloody snake, then I snapped out of it and hit the emergency stop.

 

[northwest]

So the lathe job turned out okay, it is a tool to measure offset:



You mount a dial gauge in it :



then it goes over the spigot to measure the protrusion underneath. Been meaning to make one for a while now.

A mess ,a complete mess .
Yesterday my brother decided to celebrate the "Angel Monday" (the monday after Easter) in our land in the woods ,so I've had to dig out a table from the storage room.
He then decided to go inside and make a complete mess opening boxes and leaving them around ...
So I got upset,edit angry as hell.
So I've taken the situation in (out of really) control and started to moving (throwing) everything outside and started to separate what's garbage and what's not.
Dismantled my homemade welder and saved the biggest microwave transformer to make an wire wound inductor for the CEA welder project (which I actually have most parts for it )
Get rid of two drills because one isn't worth any time or effort in repair and the other one was an accurately well stored piece of junk .
Thrown a lot of cardboard power tools boxes including the ones belonging my inverter welders (just taking space for nothing)
A two cylinder air compressor pump because not worth to keep since I've never done anything with it in 5 or so years I have it living on the shelf, taking place as well.
Plus it's only capable of 200 litres minute and that's was in 1956 when it has been produced.
A bunch air compressor related parts which I really don't need, and if I need them a day I'll just buy new ones.
Discovered that the Fein foundry grinder I've bought few weeks ago by mistake of course, has a grenade armature so that's why it doesn't work.
Impossible to find the parts for it
I might be lucky in the future and find maybe a power drill motor I can fit in it (very hard but not impossible) , reducing the RPM too which would allow me to use bench grinder wheels in it (it will have a guard anyways) , I've decided to keep it .
Anyways a load of garbage stored for years and actually good stuff laying around and getting ruined or lost.
I'm actually going to get rid of many useless stuff.
I always get surprised by the amount of garbage is stored in the storage room.
Actually it's well stored too like the burnt drill .
Both amazing and hateful because it's not stuff I stored myself and both my father and my brother always have to say I keep bringing useless stuff at home when they store even used paper cups from the job sites .

A brass thing for the grate riddling mechanism on the stove. Trying to get rid of as much of the chrome/nickel fittings as possible. Already made new door hinge pins, air control levers/rods from brass, & replaced those. Acorn nuts replaced with brass. This, bar the door handles, is pretty much the last part to sort. Bottom one is the replacement.

At least you're getting somewhere now!
With so many faults I'd check all the ground points as it seems something common to all these things has failed.
This might cheer you up

Ended up buying one for 80 euros it should be compatible because iaw 59F ECU family have all the same identical pinout.

I got up this morning, bit of a result again and by ten thirty I was in front of the lathe, finished an hour ago, absolutely drained, but I was quite productive:
Chucked a bit of .303 barrel in the machine:




.303 Chamber reamer and off we go:



Bit more to it than just making a big hole:



This is a headspace guage and the .303 Brit round is a rimmed cartridge so it headspaces from the rim, when I was happy with it I machined it parallel and left a bit in the middlefor some knurling, set the knurl to 20mm and it came out okay, not perfect but okay:





Did more than one though and more than one caliber:



Very much winging it and when I had done I machined 3 thou off part of the end so you can check max and min. As these are made using my chambering reamers I can offer these to the people whose rifle I have rebarreled and they are making the ammunition to their exact chamber.

 

[RichardM]

Made some brackets up to upgrade the depth gauge I had fitted to the TS head.




Also made fittings for the lathe compound and ordered an encoder head and more magnetic tape from AliExpress.


Slotted a piece of alloy bar to take the magnetic tape and stainless cover.




More pics when the new read head arrives.
