+1 on everything that Roderick said.

"Dinnae fash yersel"

I lost faith in teachers when one told us that the crankshaft bearings in a Hillman Imp engine were made of chrome-vanadium.

Well, you missed this one,

Good grief! Thanks Nick, makes you wonder about the main dealers, doesn't it? Bookmarked for future reference.

Apart from regretting posting the photo now (only kidding!), here's a story expanding a little on what Mark says about proprietary fluids,

I recently changed the clutch on a Citroen C1 - which is the same car as a Toyota Aygo or Peugeot 106. You have to drain the gearbox oil as the driveshafts need to be removed. A quick check of the manual revealed there is only one approved oil - Mobil 75. Wanting to do it right, I started trying to find some (it takes 1.75 litres). According to the Mobil website, my local distributor is, surprisingly, Kwik-Fit. Phoned up and was met with the audio equivalent of a blank stare. "No idea what you're talking about, mate, just get 75W-90 from Euro Car Parts, that where we get ours."

A while later, after trying a few other leads, I thought I'd try the Citroen dealer. A bit of confusion and a check on their computer later, they came up with "Oh, we can get it, it's something we'd need to order specially. It'll say Citroen on the label but it's the proper stuff. The price? £119.00 per litre"

Needless to say, I just drained the old stuff into a clean container, and put it back in, topping up with the generic 75W-90.

I wonder how many Citroen / Toyota / Peugeot dealers actually use the approved stuff when doing a clutch change? Comparing the specs of the proper stuff with the common or garden variety does reveal that the dynamic viscosity figures are quite different.

+1 on what Jason said, don't ask me how I know...

Although it's a learning experience, I guess.

Rob

Well, that's nearly an extra half a tub and half a bunch per day!

Who was it said "We've never had it so good"?

Just found this photo online and thought this thread would be the most appropriate place for it.

+1 on what Harry says - afraid it's the nature of the beast that is Youtube.

Rob

Bernard beat me to it, the only things I could add are the slot is 5/16" deep, and the grubscrews for holding the tool are centred on the slot and 1/4" in from each end. Central hole from top to bottom for long Allen head capscrew into a T-nut to hold it onto the saddle.

Rob

+1 on what Steve says, at least as far as tool height goes. I can take some measurements of the standard Taig toolpost if you like, but it will be tomorrow.

Rob

Speaking from a position of very little experience, I've never been able to get my head around using a rear-mounted toolpost and normal forward rotation (with inverted tool) as the cutting forces would try to lift the back of the saddle. Surely not what it was designed to resist?

However, so many people swear by it, it must work

Also confused by SOD's assertion that in normal use a front-mounted toolpost can lift the saddle??

Rob

But that situation wouldn't be any different to the OP's current position - no paperwork would have been created, so the new owner would need to have it certified if they wanted to steam it in public.

Rob

The Mythbusters TV program have done a number of features with water heaters - the resulting explosions WERE spectacular, the average American water heater being far larger than a model loco boiler.

Rob

Not if you buy a modern car workshop manual from (that well-known publisher) - the photos are blurry and the paper is very poor compared with those from twenty or thirty years ago. And they are now paperback rather than hardback.

Rant over and apologies for side-tracking the thread.

Rob

I think there's a danger of getting drawn down the rabbit-hole. If you receive something you know is fake, just delete it, forget it and move on. Wanting to do something about it is a normal reaction, I suppose, but pretty much a waste of time and effort.

Rob

Just for info, Blackpool South Shore Lidl has accessory kits (circle cutter, etc.) and consumables, but no actual units.

Just to throw the cat amongst the pigeons, ANY file that you download from the internet should be virus-checked. Although it isn't as common as .exe or.zip files, .jpgs can carry a virus / Trojan / malware so don't think you are immune.

Best (but not infallible) protection is having up-to-date security software on your machine monitoring downloads, and to keep up with operating system updates as well.

It's all about what level of risk is acceptable to you.

Just to keep this more on topic, I look forward to seeing the new forum software

Rob

I don't see why not. I would use a lower resistance pot plus a fixed resistor to make the total resistance value equal to that which you currently have e.g. if it's a 1k pot at the moment, get a 250 ohm pot and a 750 ohm resistor on one side or the other (determine which side by trial and error or by working out which quarter of the range you are using now).

That should work

That was what I thought originally, but gradually became convinced it was an installation issue. Then read the subtitle of the thread which confirmed it.
