I live in good old Norfolk and have still not seen MEW300

The most economical spiral flute tap is the dearest one you can afford, it will pay you back many times!

As you say it can get a bit crowded with 6 but there will come a day when you wish you had them,until then leave a gap between tools.

Can’t understand your reasoning Noel, some Machine manufacturers use them from new,and they don’t get a set in them when not used for a while. My Fenner one has been on my S7 for close to 20 years!!

Waste of time using engine oil it absorbs moisture better off using hydraulic oil.

Through hole helicoil inserts are different to the blind hole version, they have a center coil that is kinked outwards to hold it in position. I have used them with great success. Have a word with the man at Tracy tools who specialises in inserts.

You could fit an adv as they do on trucks!

from memory it should look like this. sorry for the poor drawing but can't get veto the engine to take photo.

Sorry the phots have disappeared, will have another go

Try this one,I have made Guys catches but find them a bit of a PITA.

If you think telescope are bad try riding mine with 1/4 elliptic front end!

Sorry but can’t see your problem, spindle thread is not for concentricity the the longitudal and cross registers look after that. Measuring a collet chuck runout that far from the spindle I am not surprised at those readings. As for the readings from the chuck how old did you say your lathe was?

Well done Graham something different and useful, also something to do with metal for a change. Look forward to updates.

Our leak compound has a keyed flange on the crank with two M8 socket headed grubscrews screwed through the flange directly over the key. Lateral movement is taken care of by the prop shaft thrust bearing mounted on a keel block.

What if you start with he job vertical and finish up as per the last post then position job horizontal you would only be left with two tiny radiussed corners.

I made a 2 inch siren for mine and it drives the local dogs mad but I can’t hear it!!. Some things just don’t scale.

Sorry Tony but not all stainless is rustless. Check with a magnet

I make and fit a lot of stainless fittings and never have trouble with galling because when assembled all parts are lubricated with either copaslip or hydraulic oil. How blingy they look is entirely up to you, as machined, scotchbrited or polished. Scotchbrited finish is good on vintage bikes as it looks close to nickel. Don’t forget that corrosion resistance is greater the more highly polished it is
