Stanley tote tap set ...

[mikey78]

Hello guys,
My next restoration project is a nice stanley 62 ...
I thought it was an easy one, just cleaning and sharpening : I was wrong :?

The tote threded rod doesn't "grab" in the threaded hole in the sole

At the moment my best option is brazing/filling up the hole and than re-tapping ...

This takes me to the point : I need a tap set.
I've done some research and apparently I need a non standard tap :
7/32 20 tpi withworth (am I correct ?)

Anyone coul help in finding this tap set ? ... I would consider any option no hurry at all !!! :wink:

Have you checked that the rod thread is good before doing all that work on the sole.?
Maybe a helicoil would be easier?

Why is it not grabbing? If the hole or the rod are damaged then a tap wont fix that. You will likely need to re-thread, in which case go for a more standard size as that's a weird one.

There a 12-20 thread size.

No need to tap anything if the threads on the rod are in good condition. You could rebuild the sidewall of the hole in the body casting with a strong epoxy compound, using the threaded rod itself (well waxed of course) to form the reverse threading. This process is used industrially so it can most definitely be strong enough, if you use an appropriate epoxy.

P.S. Congrats on your no. 62!

Had to look up a 62.
On this pic on amazon there is some kind of brass adjuster under the front tote.
Enlighten me someone.

Retap to M6 it works a treat, and use a length of M6 studding.
I also have a 12/20 tap a die.

The rod thread is ok, and if it wasn't It would not be difficult buying a new rod as a spare part !!!
Helicoils . . . to me they look suitable only for standard thread, do they exist in the "withworth form" ?

Rod is not grabbing because the threads in the hole are 65% stripped , I'd like more restoring the plane in its original conditions, if I can not I go for a standard thread !!!

 

[mikey78]

swagman : are you suggesting a place where I can find the tap set ?

 

[mikey78]

ED65, as you suggested, using a strog metal suited epoxy was my first idea,
but I was told by a machinist that cast iron and epoxy have different strenght and, of course,
different elastic module ...
So whenever the tote rod is under pressure, he said that will be remaining metal thread in the hole and not epoxy thread to faight against the pulling action (hope it is clear )
This statement makes sense to me ...

I will if I've no choice, but probably I won't ...
What about your tap and die set ? Are you by chance saying you want to sell it ???

Different plane. That one has an adjustable mouth.

No sorry.

I don't know a source of the taps or dies for the Stanley threads. But I do know that they were an American thread, based on imperial dimensions, but definitely not Whitworth.
If you really want to re-tap to the same thread, don't look for anything with Whitworth in the description.
You could try a search on the old tools list archive or some of the US forums.
Wax and epoxy sound better to me.

Don't forget you will need a 'bottoming' tap, for the blind hole, for best results.

I would be wary of brazing the hole, you could distort or crack the cast iron.
Clean the hole and thread and epoxy them together, if it lasts o/k if not M6...

:shock:

This is really confusing me . . . everybody in the world says withworth ... you say it's not :?:

Have a read of this thread, especially the pdfs linked to by Swagman.

It's not the sort of BSW coarse threads that were in common use in the UK up to about 20 years ago, so would not be found in old stock from your local ironmongers or garage.

They use English in America, but its not our English...

why not may your own tap using a tote screw? it only needs a flute cutting in. you could then make a brass insert, drill out the old and replace using soft solder or epoxy.
