Update: Since I posted this draft in February, I have improved and completed the flowchart. The updated version of this flowchart is at my website
H-frame: dedicated to the vintage Black & Decker Workmate 79-001
I'm leaving this original posting here, but I would strongly recommend using the flowchart and complete Type Study at the website.
-----------------------------------------------------------------------------------
I have created a sort of flowchart to determine what the Type designation is for any particular Workmate Model 79-001. This has been a common question from owners on this thread
So I'm asking the owners here to try out this first draft on their Workmates and let me know how well it works. I have two main questions (1) Is it understandable, so you can apply it reliably? and (2) Does it give the right result? Thanks.
Note that this applies only to the 79-001 models, the first Workmates sold in the U.S. The 79-001 included 10 different "Type" designations, sold from 1974 to 1982. The flowchart below will not work for later models, nor for any models not sold in the U.S. And, of course, it will not be applicable if a Workmate has been modified in certain ways (painted, new jaws).
I prepared nine photographs that illustrate all nine questions, but the forum will only allow me to attach seven. So, for posting this, the first photo illustrates both the first and second questions, and the fourth photo illustrates both questions 5 and 6.
[1] Aluminum H-frames? [Yes]---> continue, or [No]---> go to [6]
[2] All-aluminum "skeleton" frame? [Yes]---> Type E, or [No]---> continue
[3] All steel parts of frame are plated (unpainted)? [Yes]---> Type 1, or [No]---> continue
[4] All steel parts of frame are painted blue? [Yes]---> Type 3, or [No]---> continue
[5] Plastic rear-jaw carrier nut? [Yes]---> Type 4, or [No]---> Type 2
[6] Double-layer top? [Yes]---> Type 4, or [No]---> continue
[7] Plastic latch lever? [Yes]---> Type 6, or [No]---> continue
[8] Solid steel right-angle foot for lower height? [Yes]---> continue, or [No]---> Type 7
[9] Steel U-brackets attaching jaws to top of frame? [Yes]---> Type 8, or [No]---> Type 9
Note: The Type 5 is not included in this first draft.
