K: Tools Need tap/dies advice

Hi
Just trying to prioritise my excess of old tools and would welcome any advice on what sizes of taps and dies I may need for any Vincent jobs (C Rapide).
They’ve been collected and have accumulated over the years since the 1950’s and now I have them. There might even be many of the same size as there’s more in other tins.
Not sure I need that many die holders.

I have a neat Draper metric set in a case and these do fine for my two BM’s and general use.
Ideally I’d like these imperial ones organised the same in a set.
Any help appreciated.

Mostly, you'll need a BSF tap & die set comprising 1/4, 5/16. 3/8, 7/16 and 1/2". At least 3 of each is a good idea - you'll be surprised how many are blunt or have a chipped tooth. The best ones are of the HSS variety and ideally the dies will be the "split" variety which gives a degree of adjustment in the die holder. The taps of course come in various taper-starts and a "plug" type for bottoming in a hole - ideal too for cleaning-up existing threads. I keep 1/4, 5/16 & 3/8 BSF in die-holders ready for use; it saves a lot of swapping about.

The same goes for BSW (3/16, 1/4 & 5/16 being most used) and BSCy/CEI (26tpi) in 1/4, 5/16 & 3/8.

Yes, there are others you might very rarely need like BSP in 1/8 and 1/4 and some 20tpi larger threads.

Look in the back of "Know Thy Beast" for a full rundown; I don't intend to cover every eventuality here! You could sort them yourself into marked containers of your choice - buying full sets can be expensive...

Hope this helps.

That’s great, thanks.
Agree it would be a bit daft to get rid and buy a complete set. Just need to carefully go through them and sort by type/size.
I’m sure they’re decent quality but don’t know if storing them like this is ok. Wear
and tear etc.
Any spare I can offload as there’s someone interested.
Got the book. Will have a read.

Bearing the speed of Tracy Tools delivery in the UK I would suggest plan a week ahead and buy as you need I think the last one in the common range missing is the exhaust/cap thread tap
Apart from 3/8,5/16 & 1/4 BSF I think most of my stuff is carbon not HSS you just have to keep in mind the torque to apply. getting a snapped tap out is 'fun'

Thanks for the contact. Problem is they’re not arranged. Gonna need to
go through the lot and pair them up.

It takes a few years to collect! Plus I have sets of metric and BA. And still I find I am missing one now and then!
Neat. I need a tray cabinet of some sort like that.
So I take it that the taps and corresponding dies are together in each one.

That drawer cabinet looks like it was made for those. Wider drawer underneath for
handles.
Currently it would take half an hour for me to find what I need. Some taps I can hardly read due to condition but most are ok.
Will try to clean those up but if too bad I guess they’re no good to anybody.

To match taps and dies, I take it the tap should thread through the die with ease.

I do not think that would do the tap and die any favours, so personally I would not do that. Perhaps find a nut that threads on a tap and a corresponding screw or bolt that fits the nut, that then should fit the die you are after.

Or make male and female test pieces to see if they fit together.

I wouldn't try that at all. If I can't read what is written on a tap I measure it up with a mic and check the pitch with a gauge. If I can't get a pitch gauge into a die to measure the pitch I would run it down a suitable piece of aluminum rod and measure the pitch produced on that. Trying to thread a tap and die together is not going to end well.

Ok thanks. I wouldn’t try it either.

Looking through the tins of taps & dies and KTB book, I have all the sizes for the Vincent.
BA t&d’s are together but everything else is separated. Don’t think it matters as
I’ll more likely need a tap or a die.
I’ve never used them but will keep anyway and label the tins rather than pair them up.
