Thread: Odd ball tap, need a lend

Ken

Buy yourself a Tattslotto ticket! E & J Winter have that tap

Their mail order is reliable (if a bit slow)

Thanks jmk89, you are a marvel.

I shall contact them asap. At the price they are asking, I don't need to by a ticket in Tatts.

This forum is great, just ask a question, and someone will have an answer, pronto.

Regards,

Ken

Ken when you say No6 40 tpi I would guess you are talking about an A.N.F. thread These are a 60 deg thread , it might be easier to get the correct threaded rod or a bolt carefully file a cut along both sides of the thread and use this as a tap ?

Not a marvel - just the previous recipient of a good lead from these forums.

I would never have found out about them if someone here hadn't mentioned that they might be able to get a LH tap and die for me (which they did). Happy to keep spreading the good news about these guys .

Dear Ashore,

The tap thread is No.6x40 UNF. I have the screw to fit the tapped hole, and it has 40 TPI with an external dia of 3.55mm, or 0.14".

Finding a piece of threaded rod would be nigh impossible, and far too soft to form into a tap, but thanks for your suggestion.

If you haven't already committed to a tap from the first lead, try a model shop that stocks more than just boxes of ARF models. You most likely will find a tap or tap and drill set there as 6-40 is one of the standard sizes used in aeromodelling for mounting engines etc.

Hi neksmerj
Here is some bits and pieces of info that may assist.

Just for double checking - my Workshop Practice Drills, Taps and Dies indicates that a 6 x 40 tpi UNF thread is 0.138" so 3.55mm, or 0.14"sounds correct (the thread is meant to be a poofteenth under).

You should ask for a bottoming tap if its just for cleaning up a thread.

The taps are a fairly common available size used in the US and are not too hard to get a hold of here in Australia.

I use a few UNF small threads of this size in my black powder firearms maintainence .From what I can nut out, I believe that the 1st number ( 6 X 40 )refers to the screw gauge sizing that the septics use.

They should not be too pricy I purchased a set,taper ,intermediate and bottoming taps in 8 x 24 UNF for about $10 about 12 months ago. Don't take the first high ripoff price,some companies will try and shaft you, price wise.

I say this as a shooting colleague down the road in Gladstone was almost going to pay $70 for 1 tap that a counter jumper in that city was trying to charge him for.

I got the tap through United Fasteners (insert unashamed plug for the good guys, here) in Mackay for about $5.

A bit of a tip, is after you use your tap, put in back its little plastic box with some machine oil. If they are left out here in rust city they dull from corrosion, and get blunted by other tools and don't cut as well next time.

A tee handle is a good idea( for tapping) as it allows a proper hold on the tap. A shifting spanner is a no no for tapping. Shifters put the load on one side of a small tap and they break easier.If its a one off and you are clearing a hole you may be ok if your careful.

cheers

Hi Grahame,

Thanks for your input, your spelling has improved out of sight, just kiddin.

I have sent you an email.

Thanks to all other members for their suggestions, I will follow up all leads.

Ken

A second on E & J Winter.

Good to deal with, don't charge like a wounded bull, huge range of stuff you'd have trouble finding normally and pretty quick.

(The post office was the reason their delivery took nearly 2 months, they got it to the local P.O within a couple days...)
