What's on your bench today?

Playing devils advocate. Surely it costs more to make a saw with a million and one parts and yet home owner saws are such.

No. As the engines are made else where and then fitted into the cases. Plus they are home owners saws, so not really worth working with, just buying a whole new saw is cheaper.

Fair enough. Which is why I bought a Husky 135 for hedges and light coppicing. Disposable, sadly.

Metal costs more than plastic.

Injection moulding is a cheap and fast method of mass producing a saw cheaper to bin and replace than to fix.

Plastic doesn't shatter as easy as magnesium when an idiot homeowner drops a log on it.

Warranty parts are bolt-on, bolt-off, and a homeowner is an expert at breaking something in an impressively inventive way!

I actually don't mind the stihl clam shells and quite happily work on them. Built more than a few out of bitzas where they have been written off as uneconomical repairs.

Granted its a bit more of a pain if topend work is needed but to be fair it doesn't take long. I use a battery drill with a t28 and you can strip them to the bare bones in around 30 mins.

That said the line has to be drawn somewhere if your having to pay labour verses the value of the saw.

On my bench this avo was a freebie after visiting the kind hearted Barry (gardenkit) today - a non running efco strimmer.

Had it running fine in 30 mins Barry, including being comp tested at 155psi to. Have to say tho a plastic bodied walbro carb?? Never seen that before.

Carb was full of broken up foam air filter... Just need to sort a strimmer head now.

Nice one Martin. Yes, I knew the compression was quite good, but had not gone into the carb as I hate those plastic walbro's, and the guy was up for a new machine anyway.

 

I had swapped his "jet fit" head to his new machine, hence no head.

 

Good to see my scrap recycled!

By the way Martin, you were just in time, the scrap man turned up just 15 minutes after you had dived into the skip!

Had a 560XP in with a buggered spark plug hole. The plug is M10 x 1.0 so didn't have the kit to do it - I am well covered on the M14 ones so agreed to do it for the price of the tools plus circa £20 to cover a little of my time - that way I have the kit for future!

 

I got the V-coil kit, good quality and made in Germany, the helicoil lengths are measured in "diameters" - 1d = 10mm, 1.5d = 15mm - the length I needed was 12.5mm so took a 1.5d insert and lopped off a couple of coils and ground the top flat - not really necessary but get a little anal on attention to detail.

 

The tap is the type that has a taper guide on the end of it leading in to a reamer and then the final tap to take the insert. Don't get confused with the cheap crap ones - I need to use decent grade taps to get strength out of the finished item.

 

I also use a Loctite high grade thread lock when putting these in, many don't but I like them to go in once and never come out and the cost/time is negligible.

 

The pics are of the tap, two insert lengths, damaged plug hole, tapping in progress, tapped hole and then repaired hole. You wouldnt know the insert had been fitted and will be damn strong in use.

 

I finally get a bit of heat with a plumbers lamp on the cylinder to make the Loctite go off.

Scary thing Barry I done the comp test first and wasn't expecting anything close to 155?

 

Certainly wasn't expecting to see a plastic bodied walbro tho. Never knew they existed! None of the walbro carb kits I had fitted. Cleaned it all out etc and primed it up with the bulb. Fired first time, released the trigger pin and started the next pull. Just need to work out a replacement air filter as the original was just flaking and fell to bits but couldn't get anything simpler to make or source something to fit.

 

Almost feel guilty it was a cost free fix.

 

I will be raiding your skip more often at this rate! Father come around just after I fired it up and was already hinting on it being a light machine and how he could "use that" in his garden...
