vulcan bomber

I happen to know a bloke that does this....

Send it to a machine shop while they have something very easy to position to and they will put a drilll right down the center of it, the treads sghould just peal out then.

If it stops raining I'll pull one out my Case and mesure it up.

Friend of mine bought a cheapish plasma cutter to save some time in his workshop, reckons it doesn't and wouldn't bother again and just stick to the 4½ grinder.

The subject of files came up in the tools section fairly recently, have a look in there

You would need to know the material spec and the process(s) it would go through. It could be case hard, nitrided etc ..

Yes it can be done, it'll be very hard on the outside so it's going to cost a few quid in tooling to do it.

With the best will in the world, I still can't understand where you get £50 from for these spacers.

I had a 1.2 transfer box on my 200TDi for 5 days, it was bloody awful. With the 1.4 box on it will tow 3.5 ton trailers over the speed limit relativly easily but the power delivery isnt there for a 1.2... 5th became almost obsolite when unladen. The transferbox is a fairly simple thing to change, if you and a mate can hold a spanner between you then you'll be able to change it yourself.

Carbide have a very narrow band where they work properly, surface speed, feed per rev and depth of cut. And that's assuming your using an appropriate grade. Get any of them wrong and it won't look good.

I've got a Demand Engineering exhaust on my 200tdi, granted it's a defender one, not sure if they do one for conversions but there a great company to deal with so don't hesitate to get in contact with them.

Personally I don't see the point In a VFD on a manual lathe. RPM isn't that critical within the couple of hundred RPM.

T27 you want, same as the low fueling screw on top of the boost diaphragm.

Your correct. It allows more advance not alters the advance curve, that's what the shims do....

Can you not make your own? I plan to do this on my 110 one day
