A number of people responded to my original posting of:
HP71B - #$%!!#!$@ screwed, on November 08, 2001.
I had fully intended to thank any and all of you for your help, but by the time I got the proper tools and figured everything out the posting was gone. Anyway this is my resolution.
Don't waste your time on a unit that uses 1/4 inch bits for the HP71B unit. It will not however work on one of the deeply recessed torx screws on the HP71B Case. The exact tool for all latter model HP71B units I used with success was as follows:
WIHA Proturn 657/T6 x 40 Item # 95713 $4.10 http://www.wihatools.com/957serie.htm
a. Tip size = T6 - This is a standard blade
b. Blade Length = 40mm
c. Blade Diameter = 2.5mm
Some people that posted a response to my original question said that it takes a T7. While that might be true on some older units it wasn't on the latter units I have. I also wondered if there are different types of torx bits. The answer is yes.
a. TORX - Standard tapered style blades
b. TORX Security - Center point hole on blades - Nipple on screws - can't push solid standard on
c. TORX Plus - Straight edge blades (Vertical)
The WHIA webiste has a lot of useful information on the subject, as well as many fine products as well. I contacted them when I found the one torx screw couldn't be removed with the 1/4 inch bit. One of the employees eventually put me in touch with a designer type person that helped me find the exact tool in just a few minutes. Great service and resolution. They stock the units all the way down to the rare T1 in this series. But not the 1/4 version. The quality is really fine as well.
