Based on the numbers that I have from the survey, Here is what each item costs:

Item Qty Price
M14X.8 Triple Start 14 $58.08
M13X.8 Triple Start 33 $47.10
M12X.8 Triple Start 25 $43.20
M11X.8 Triple Start 8 $63.45
M6.4x0.6 (Bock #5) 18 $22.45
M7.9x0.6 (Bock#6) 17 $23.50
M6.5x0.5 (Jowo#5) 12 $22.45
M7.5x0.5 (Jowo#6) 22 $23.50
M8.5X1 (Bock Section) 9 $34.35

NOTE: All taps count towards the price for that size tap. So we had a total of 14 for the M14X.8 Triple Start between the plug and the bottoming and that determined our price.

Item Qty Price
M14X.8 Die 10 $78.40
M13X.8 Die 23 $70.00
M12X.8 Die 19 $70.00
M11X.8 Die 7 $103.60
M8.5X1 Die (Bock Section) 8 $74.20

Based on the prices above, I will need a go/no go decision from everyone who is interested to see if we go forward.

Once I have everyone's response by to go or not, I will do all of the other paperwork to get us started, or have the thread closed by the mediator.

I am wondering about the diameter of the JOWO #6 Bottoming Tap.

Although the difference is only very small, and it may make no difference in practice,
other sources I have specify it as:

M7.4x0.5 Bottoming Tap (Jowo#6)

Mal, I noticed that too. If anyone can shed any additional light on the actual size, I would appreciate it.

I can't speak from authority, but I can say that some JoWo #6 housings are very tight when I screw them into sections made with my M7.4 x .5 tap. To the point where I'm thinking about getting one of the M7.5 x .5 taps to get that little bit extra slack in there.

I believe the 0.1mm diameter difference gets divided in two, resulting in 10% less active thread each side (0.1mm / 2 = 0.05mm, 0.05 / 0.5 = 10%). I can live with that if it means I can get the housing out of the section without mangling parts.

I get two different answers. Another member pointed out that the JOWO #6 feeds were really tight with the M7.4X.5 and that he thought the M7.5X.5 might make it easier to remove the feed with out destroying it.

Sorry, however in the last group buy we bought the M7.5X.5.

Something else that sometimes confuses people is the drill bit size to the Bock #5. The tap is a M6.4X.6 which means that you would use a M5.8 drill bit. In fact the end of the Bock#5 feed is 5.9 mm in diameter and it would not fit in the 5.8 mm hole so we have been advised to use a M5.9 drill bit.

If the current price breaks remain valid, I confirm my initial selection of:

M14 x .8 x 3 plug tap
M14 x .8 x 3 die
M12 x .8 x 3 plug tap
M12 x .8 x 3 die

And add:

M7.5 x 0.5 bottoming tap for JoWo #6

Thanks for taking on this challenge once again :)
