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

[FoxZulu]

Thanks to @Hood & @fizzy I now have £366 less in my bank account. I do however now own an Optrel Crystal 2 welding mask. It says on the box 'you won't believe your eyes'. Well I tried it out last night and I was absolutely amazed. I can now actually see what I'm doing so clearly.

Will be back out in the workshop tonight wasting more ally and argon

Ps thanks @fizzy for the heads up on the sale price from Inverter Fusion. Very good people to deal with.

I hunted around a lot to find that price!
Yes they were very helpful.
The mask is so awesome I might even get the hang of tig

Most test gauges have the check valve in the stem , just had a look ..put " compression tester " in to Amazon UK , most have a range of adaptors there might even be one for various two stroke machines .

Perhaps this may explain things better

Two stroke small plant stuff......

When things get worn in the cylinder , gasses under a slight pressure find their way into the crankcase . This has the effect of causing the machine to pulsate/ undulate in RPM when on full throttle , it often blows fuel mix back through the carb onto the air filter .
So running a two stroke chainsaw , disc cutter on full tilt without the air filter on is a quick way of seeing & hearing evidence of crankcase compression .
Doing the wet & dry compression tests will confirm things either way .

The picking up/ scratching you see in the bore through the exhaust port usually happens when things have either been run on the incorrect fuel mix resulting in little or no cylinder wall lubrication ( common), big lumps of spark plug deposits break free , the machine has been run without an air filter ( common ) or the normal engine wear over time has worn off the hardened coating on the cylinder wall and picked up the softer metal the hard lining was sprayed on.

A well looked after machine that simply was worn out often used to be brought in for a service as the used noticed it was not running as well as usual despite a new plug & air filter being used then there would be a light grey area on the thrust side of the cylinder and a low compression reading .

Leaking crank seals is also an indicator ..where you cannot set the tick over in a normal manner ……. slow enough to not bring the clutch into play .

Testing a crank case for compression is not usually worth it time wise & because of the customers way of financial thinking ...............… but if you want to make one :-

You can make up a carb plate & and exhaust silencer plate with a bit if old inner tube rubber for a sealing gasket , the carb plate has a lorry tyre inflation valve stem brazed in it , pump it up to about 8 psi and do a 20 second leak test . As I said it's not usually worth your time . Occasionally I had a chainsaw brought in that others had " repaired " & found the big end bearings & crank seals well worn but someone had put a new barrel & piston on the machine fairly recently but, "The machine would not run well " . That's when I did an occasional crank case pressure test so I only had to slip the carb & silencer off .

Yes I know 99 times out of a hundred you can pick up a machine pull it over once and be right about it's state of repair , sometime you need the extra 1% info & bits of kit , especially when your hire fleet is 70 plus machines and you are the authorised dealer / repairer for several different brands of machine .

I'm always concerned about air leaks on a engine because can cause it to run lean and you know what this can cause
Thanks for all the details and advice you gave me ,if you have other to share with me I'm happy to learn more

Among some other components, I got some thermocouple amplifier (Digitiser perhaps, output over SPI) ICs.

I'll admit, I didn't realise a SOIC package was so small when I ordered.

SOICs are HUGE! Try a DFN for size...

A few days away.
A few freebies.

This is what I got "gifted" to me.



The book is new and the sounds work.
The fire logs, again new.
The chain saw oil is opened. But full.



A Jar, good for solvents.
Croc clips.
Brass hose thing.
Pliers.
Blue Ring crimps.
2 small G clamps.
Solder.



A almost complete RC components Key way kit.


Best for last.


Oregon Chain saw, half a tank of fuel. But no chain oil.

Oh wait, I have some.

Yes it does work.

All because I helped a couple dump heavy items in a recycling centre, as the staff were to lazy to help.

I once helped someone at the tip dispose of a 110v transformer, 110v light on a tripod and a 110v splitter, how do these peoples brains work! not even hard of ebay…….

Some steel - this is half of it, forgot to take a photo until I’d put the rest away

Today I acquired.
Absolutely fk all and ain't happy

This at an online auction.
They say it's a 48" - looks bigger to me what do people think?

48 is a fair size. Probably about right I would ssy

Looks like a good machine I think. Pretty hefty.

I have been watching ebay for a year or so looking for a VDI30 rectangular blank for a reasonable price. Got fed up so decided to get one from Cutwel as they had them a bit cheaper than normal but it was still about £110. Then what appears on ebay a week later, some blinking VDI30 blanks, made an offer on 2 and got them for slightly less than the one from Cutwel cost me. Now all I need to do is wait until someone has a Capto C4 extension on ebay cheap and I will be able to make up another couple of VDI to Capto adapters.

Pic of the blanks.

Pic of what they will hopefully be turned into one day

Looks good. Nice big heavy lump

I am going with 6 foot, at 4 foot it looks to narrow to me.

That's what I am hoping! If so a nice bargain. Just wish it was a box pan one but they never go cheap.
