Custom Tapped Holes

[tsaulmon]

Hi Everyone,
I have been working on creating a new set of tapped holes for our industry. We have many unusual threads that we have to use. For example, I am starting my list with a 9/64-40 tap. I did the part of creating a new list by using the "How do I create my own Hole Wizard standards Database? faq559-1183" FAQ. I then added the specs for my 9/64-40 hole. Now when I try to place my hole, I get an information box that says "The dimension value 0 is out of range. The old value 3.3 will be restored" I can tell by the 3.3 (which is the tap drill for an M4 tap) that it is looking for the tap drill size. So, I see that the lower part of the Hole Specification menu has a section at the bottom for Custom Sizing that includes a box for inputting tap drill size. When I do this, and input 2.9 for the tap drill size I get an Information box that says "Error: The tap drill diameter (2.900000) cannot be larger than the thread diameter ()". I have not left any of the value boxes blank when creating my hole in the database (per the FAQ above).

What am I missing? Any help would be much appreciated.

Thanks,
Tim

Perhaps you made the tap 9/64 in radius instead of diameter?

I used diameter dimensions for all fields. 2.9mm for tap drill, 3.6mm for hole size. Pitch is the only one not a diameter at 0.64mm. Then I filled in the other boxes with data as close as I can figure without having specific information on them. They are sewing machine screw threads, so there is very little spec. data available for them.

I have seen this when the drill tip angle was set to 0 degrees. Could that be it?

Are you applying the units (mm) when typing the drill sizes?

I am doing the thread as "through all". But, even with a depth, I did use the degrees of 118deg. (I tried others as well). But, with thru all, I don't need an angle. And yes, I am using the units. I am posting a screen shot of what I am getting. Again, any help would be greatly appreciated.

Thanks,
Tim

Have you tried using smaller size just to see if it works? Pick a really small size first (say .5mm) and then increase until it stops working.

Hey Limey,
It will even do it at 0.01mm tap drill size.
