Mezz Wavy Tap

[Mase]

I know I can buy one from Atlas for $380 but that seems a little high. I did a search on AZ and could not find info on other tap sources.

Do I need to pay the $380??

Only if you want to have it on-hand for the once a year that you'll use it.
Let's see, you're how old now ? Time to do the math.
Compadre, it's your money. Spend it on whatever you want. In the meantime,
have a Happy Holiday.

I bought one of the Wavy pins, cut three grooves down the side, creating my own tap. It works just fine.

Thanks Ryan. I have done that before also. My customer has offered to buy the tap for me so I have an out. But I may try the pin trick first.

Using a dremel tool with the quick change cutoff wheel will do a great job. I usually cut three channels, and make sure to go BELOW the thread depth a bit so it cuts the minor effectively. I make a straight cut, then re-cut at an angle so the cutting edge has a relief to it. Works well when you don't have the $$$ tap

While I have done the same procedure to a pin to create a 'tap' as Ryan and now Dave describe,
I would like to offer a note of caution. A 'true' tap is oversize for a reason; it provides tolerance.
Converting a pin to a tap offers no such tolerance. Damage to the shaft can occur if care is neglected.
Not all pins of the same pitch are of the same exact OD. An undersize faux-tap coupled with an oversize
pin in the cue can be a dangerous combination. Excessive outward pressure could possibly split the shaft.
A lot of 'ifs' 'ands' & 'buts' here but neglect the caution and you could be replacing a $300 shaft.
I'll offer a few tips to lessen the danger.
You'll likely have to tap and re-tap the hole several times. Liberally coat the tap with wax each time.
The wax will reduce friction and will slightly soften the skin of the interior wood surface.
The orig. Asian ball-screw tap did as much to 'form' the thread as it did to cut the thread.
You'd want that interior wood to be somewhat malleable.
This next tip requires a higher degree of caution. While tapping under power, slightly side-load the tap.
Angulation of the tap will cause it to over-cut the hole to a varying degree.
This works in wood, not so much in steel.

This all may become a futile attempt to exercise my typing finger because the new version of the Asian
Ball-Screw thread tap is now available. Pretty fairly priced too. Let's see, where did I get that Abalone ?

HTHs, KJ
