IMHO the chart Poppajohn created from the work of others is outstanding. I am only writing to correct what I believe to be one important historical omission. We all stand on the shoulders of the work of someone else. Indeed, at least in the antique and collectible tool world, the concept of a "Type Study" was pioneered, financed and completed by Roger K. Smith, Athol Mass. He deserves to receive full credit. In his tool collecting world, it was a labor of exploration for knowledge and the need to understand versus the desire to influence which plane one buys. I'm sure Roger would be pleased to see the new chart. It summarizes Roger's work and the add on by others in a manner most spreadsheet enthusiasts will love.
Ed., 10/30/2006: Well-spoken, and incorporated into introduction.

DONE. Blade logo 1909 only - "STANLEY" 5/32" tall - nothing else

There are a few changes that don't seem to be in any of the Type Studies which you may be interested in including:

  1. DONE. Early Cheesehead Frog Screws didnt have the chamfer at the top edge.
  2. DONE. Early Tote and Knob Screws had cut threads and later had rolled threads.
  3. DONE. Early Lateral Adjuster Discs were free-wheeling but later were fixed.

  4. Change in shape of Frog around Lateral Disc

  5. DONE. Early Brass Nuts (Tote n Knob) were straight sided, later were waisted.
Not sure if you have had any comments regarding accuracy:

J Davey 11/01/2006 (Not yet posted)

  1. DONE. Tote and Knob Screws had "cut" threads prior to (about) 1910 - "rolled" thread afterwards.
  2. DONE: Tote and Knob Brass Nuts had straight sides prior to (about) 1920 - "waisted" nuts afterwards.
  3. DONE. Early Cheese Head Frog Screws didn't have the chamfer at top - up to about 1890.
  4. DONE. Early Lateral Discs were free-wheeling but after 1930-35 (about) they were fixed.

  5. Frog Screw Washers stamped from reject Try Squares have been observed in the late 1920's - these are blued with the graduations still showing.
  6. Lever Cap Spring Rivet changed from small to larger head - maybe early 1900's
  7. Early Frogs with lateral adjustment had a kind of "neck" at the top which retained the Lateral from moving too much - after about 1910 or 20, this was open and the Lateral had a lot more movement. In Bedrocks, Type 6 have the neck but Type 7 doesn't.

I am pretty sure the O came before the S and S flowed through after WWII when they changed to rounded corners on top of Iron and Back Iron. Irons up until WWII were laminated (with unrounded corners on top, although some of this style have been observed with unlaminated blade.

J Davey 11/05/2006
DONE. Regarding the second chart: #4 1/2 H & #5 1/2 H have 2 1/4" Iron not 2 3/8 as listed in John Walter's book. (posted)

DONE. There is an error with the Depth Adj. Nut. As far as I know:
The Pat date dropped off and the thread changed from right to left at the same time - end of Type 6. Type 6A had no date and lefthand thread. I have seen small Nuts with no date and right hand thread but they may have been non-Stanley.

Hi John,
DONE. Early 5 1/2's had a 2 1/4 cutter but later had 2 3/8. The change may have been in the forties - can anyone help with that?
Now *that* is slicin' and dicin', my friend. Love the detail. Thank you! I wonder how the narrower blade was justified (sloppy, I'd think) unless casting width also changes. Is there any potential mixup here with 5-1/2 and 5-1/2H .. ?? Posted in unresolved "additional info" link.

Spike Cornelius Sure enough, my type 11 has a 2-1/4 inch blade!

DONE. Type 6A should be last of the Pat dates in the nut as per Smith first line of notes on Type 7. (not Type 6 as I said) - I checked on my #3 and it has all nibs and RH thread and Pat date. You could run the Right hand thread as "grey" into the start of Type 7

DONE. The Circular Hole was at top of Blade until Pat '92 - but a few have been observed with the "Two-line" Logo and Hole at bottom. From this I would conclude that they introduced the change when the patent was lodged and then changed the stamp when approved in April '92.
DONE. So, on your chart you could have "Hole at Top" finishing end '91 or you could have a little Grey in there - but not much. Probably better to finish "Hole at Top" at end '91.

DONE. P.S. did you know that early back iron/cap iron screws didn't have any knurling? I think Type 6 would have been the last without the knurls.

11/8/2006 Attached is a pic of some frogs from Type 5 on left, two early Type 6, Type 7 to 1920's. They show a few variations not included in any Study before. Note the shape of the casting at top of Frog around the Lateral Adjuster.

RE: Lever Cap Colors
Ed Minch:
The word STANLEY was added to the lever cap in 1925 with the type 13. The orange color was added just after that, along with the advent of the kidney shaped screw hole. In the late 50's the color was changed to yellow and I have only seen the yellow on any plane painted blue, or the later maroon (70's). there is one anomaly - Stanley had a 4 sized and a 5 sized plane with a bed made of bent steel so that it would not break if dropped, the S4 and S5. To go along with this feature they included a malleable iron lever cap, and it's logo background was painted red - these planes were made n 1925-42 and I have never seen an early one to know if it had no paint in the logo.

DONE. Found note on 'net that only Type 16 had black logo background.
DONE. Fix the frog receiver smaller bearing surface - terminates 1907 in gray.
DONE. Type 5, 1885-1888 - first lateral, no disc (crossbar), 2 patent dates
DONE. Type 6 is only 1888 - 1890, then 6A 1891-92

DONE. Type 6A, 1891-1892 (Missing entirely) See Davey notes above.

Ed. 10/30/2006: None yet incorporated into megachart. Keep 'em coming!
I've seen both red and orange (faded red?) Comments?

RE: MAC Browsers
11/17/2006 Thanks to feedback and patient exchange with Scott Stager, we found and repaired the silly HTML differential that was causing the misalignment problem. Please report if you see other oddities.
