Tap Extensions? For threading

[r6100mph]

Does anyone know where I can find an extension for hand tapping new threads?

I need to install new threads in a motorcycle cylinder head, but the location of the hole is a few inches below the head.

I need an extension that will go onto the tap and still be able to use the hand wrench.

or anyone have any ideas?

Thanks!

Can you put the tap in a socket?

Schroeder makes a purpose built wrench/extension kit...

can be found at sears and a few other places:

Long tap handles and tap extensions are available from any machine shop supply such as MSC, etc. So long as you don't have to reach deep into a counterbore, these will work.

If you need to reach into a deep counterbore, I would recommend an extension tap or pulley tap. An extension tap is basically a standard tap with a much longer shank. Usually 6" in the smaller sizes. Regal cutting tools is one supplier of these in metric sizes, standard sizes can be ordered from MSC.

I really appreciate the replies! Thanks!

I can't put a socket on it because the void going down to the spark plug hole is pretty narrow.

Plus I need the "square" type of extension and I can't find a socket to fit the square end.

If you can't put a socket on it, you likely won't get a tap extension or extended tap handle to fit either. Depending on the clearances, you might be able to "customize" something. 8-point sockets are readily available at decently stocked Sears stores.

Since it is a spark plug thread, you might look to see if the automotive tool companies have a solution for you. I suspect the price of an extension tap from Regal will shock you, unless it happens to be a stock size.

A tap socket would probably work.

When faced with this problem, the first thing I look at are 1/4" and 3/8" socket extensions (reversed). If the slop is a problem (with the tap dropping out), I have used two solutions.........drill and tap for a "set screw" in the female side, or use a bit of silicone, if you have a day or so for it to set up. Cleanup is quick and easy with silicone.

I use either square or eight point sockets to hold my taps when I need to use them in an obstructed area. Do purpose built tap sockets have a clip or something to hold the tap in place? If they do I think I just found my next tool investment!

Look for a pulley tap.

They have an o-ring. Of course 8-points work too, but only for a few sizes.
