Just want to say thanks for all the input on this thread.

I did manage to get the new nut to run down by gently using the first whit tap into it.

seems fine.

Its loctited on now so hopefully cannot be lost.

MG , silly.o.d

I don't think your wrong at all, Im not sure what this blooming thread is!!

But tomorrow I'll try and take a shot with that 60 deg gauge on on it just for comparison.

I do wonder if it's just odd ball, kind of 8BA but with less tpi

Thanks John.

I hoping you could be right, as the new 8BA nut made for me does go on for Almost two turns.

Im hoping running a 8BA die carefully down will clear it !! One is on its way from eBay.

That is a beautiful locking screw you have made there.

Ive been taking my time getting this reel working nicely and this is the last thing to finish it.

Inside Its stamped RB who I believe was Robert Borthwick who worked at Hardy's 1890 to 1920.

Gents Thanks for the replies.

This shows the brass 8BA nut that I tried first.

Thanks Michael,

All info is appreciated.

Yes John is correct it's from an early hardy perfect. I did do some research before getting the nut made and even ran a brass 8BA nut down it, but that nut was not very thick

I think John could be right about oversize due to old tooling. I think I shall try an 8BA die on the stud and see how it feels.

really appreciate the help given on here.

Thanks Dave I'll take a look, it's off an old English Fishing reel.

Thanks Nigel,

Its a rum'um. That thread was cut c1910.

strangely the nearest thread on gauges I have is metric .6 60deg but that's a 3.5mm ISO !

Should have said OD of thread is .085"

looks to have 44tpi

Let's see if this works hopefully a picture will emerge!

Well the plot thickens I bought 3/32" whit tap set drilled a small piece of brass rod and managed to tap enough to cut off and try (6mm long)

I goes on but very sloppy fit I'm wondering if the male is an odd ball size.

glad I did not run the 3/32" tap through the nut I bought.

Thanks for replies

It's the male stud that is original, I had a nut made thinking it was 8 BA but sadly does not engage,

If I ran a 3/32" whit tap into the new nut will it just mess it up ?

or is it start again?

Thanks Jason for quick reply

I'm waiting on a thread gauge but just measured the male thread OD at 2.2mm got a feeling it could be 3/32" whitworth. Not 1/8"

Gents

new to this site and just wondered what the consensus is on Doing a mod to a small brass or Nickle knurled nut 5mm dia 6mm tall, which is tapped for 8BA but needed to be 1/8" whit.

Drill size for 8BA is 1.8mm

Drill size for 1/8" Whit is 2.55mm

Im thinking it could be ok to drill out and re-tap.

any comments appreciated.
