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.
 
Based on Duncan's experience I want to add a M7.5x0.5 Plug Tap (Jowo#6)

With this addition I am in for FIVE taps :

M6.4x0.6 Bottoming Tap (Bock #5) ***** - WANT BOCK #5 Bottoming Tap

M7.9x0.6 Bottoming Tap (Bock#6) ***** - WANT BOCK #6 Bottoming Tap

M6.5x0.5 Bottoming Tap (Jowo#5) ***** - WANT JOWO #5 Bottoming Tap

M7.5x0.5 Bottoming Tap (Jowo#6) ***** - WANT JOWO #6 Bottoming Tap


M7.5x0.5 Plug Tap (Jowo#6) ***** - WANT JOWO #6 Plug Tap *** ADDITION ***
 
I am in for the following, which I believe matches my survey responses:
M13x.8 triple plug tap $47.10
M13x.8 triple bottoming tap $47.10
M13x.8 triple die $70
M7.5 x 0.5 plug tap $23.50
M7.5 x 0.5 bottoming tap $23.50

Thank you.
 
I'm still in for my original request:

M12x.8 triple start plug tap
M12x.8 triple start die
M6.4x.6 plug tap (Bock #5)
M8.5x1 plug tap (Bock section)

Thanks for the opportunity to participate in this!

Same question from me
 
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.
 
Here is my list I would like. One of each.
Bock #5 M6.4 x 0.6 bottoming tap.
Bock #6 M7.9 x 0.6 bottoming tap.
Bock #6 M7.9 X 0.6 Plug tap.
Bock M8.5 X 1 tap section.
Bock M8.5 X 1 die section.
M14 x .8 triple start bottoming tap.
M12 X .8 triple start bottoming tap.

And add:

M7.5 x 0.5 bottoming tap for JoWo #6

Thanks for taking on this challenge once again :smile:
