Check how central the die is in the tailstock die holder. Some have large clearance bores for the dies to be split open and when used push the die up to .75mm (20thou) off centre which is a lot on basically a 3mm thread.

If this is a problem add 3 tapped holes to die holder at 90 degree intervals so that die can be centered , can then be closed up using two side screws.

Better with a collet, Degrease material with Acetone or IPA to improve grip.

How are you holding the die?

You could take a couple of thou off diameter

Not always, I bought a load of Carbide endmills (about 20) when they were on offer in ther flyer leaflet and they all cane in a box direct from sandvik with a delivery note with me as the drop adress.

You dont nned to be a company they will sell to anyone paying.

Even my wife has an account for getting me Christmas and Birthday presents sometimes.

Just ring up and say if you want to buy something

Its the same with MSC

Steve

The collets are very good as are the thin parting and grooving tools.

Steve

Why were they a pain to set up.

Interested as I fancy something of that design style

Thanks for the info, when Dave said, “ most people will know” I was mystified as there was nothing I could find on their website. Shame as one of the better shows.

Where is the news about no Bristol next year?

Steve

Err it started at Harrogate.

The one at Donnington was at kenilwirth before that and had aprevious home and is now at foss wayj.

Was the door a casting or a solid disk of steel.

Two experiances that may be related

We had a Colchester Master at work with a rear toolpost carbide insert upside down, reasonable machine but when I tried to part of a load of M24 A4 stainles steel bolts (316) by hand feeding as i worked in design normally but i needed these for a Factory acceptance test the next day, it kept digging in and breaking the tip. This was only cured by using power feed then I did about 50 of them easily.

Now days at home I have a MKII Colchester student, using a front mounted T2 Dickenson toolpost and a Sandvik inserted blade I had digins, changed the toolpost to a create multifix copy now goes through 316L like butter, best on power feed but can do it by hand if you keep cutting.

Couldnt see angy damageon the Dickenson toolpost but the multifix seems far more rigid,

Steve

What is not to like about been able to thread at turning speeds?

We had on at work ( old Job ) but threads were far cleaner turned at proper speeds with full form insets in 316 stainless steel.

Steve

Probably whitworth if not UNC as per my mk Ii

There is various schedules (wall thickness)

The OD is constant (10.29mm )the wall is described by schedule 10s 40, 40s, 80, etc

Such is the fun between pipe and tube

Steve

For £63 Inc vat you can get a complete starter set up at Hamilton or for£74 you can have one with a cyclone burner which are very useful. You can add more burners and neck tubes as you require them, often available on eBay or on special offer at the shows.

Steve

Why would it be documented to that level?

Its an adjustable bed i would expect most of the parts to be mild steel, might be modern equivalent of EN3 or EN1
