Meyer-Photogrammetry Scaled Photo!!
« on: February 10, 2011, 01:58:19 am »
This is one photo, demo cell replicators should look at or download.!!
Also available as an attachment is an excel spreadsheet with abbreviations for parts
445/75  =5.93
Ratio is 5.93 x .75 = 4.44 which agrees with the dimension of the upper tube holder
So true inside diameter is of the CH is , how about 4.75 I.D. with 0.375  inch walls??

CH thickness .375
(BEC and TEC  ID 4.75 diameter - a little larger for fitting the top tube bracket in) which calculates out to 4.5 inches in diameter

OT Diameter .75,  IT Diameter 0.5
Width of I7B 0.75
Diameter of ETP still a little sketchy  3.5 -4in ?
I need a clear picture of the TEC but my hunch is that Stan made them
to the same basic dimensions and then turned out the cone shape area.
Best guess is that the base of the cone was recessed by .25 inches or
same depth of TOR groove. The top of the cone was truncated and
milled to 0.5 inches to the top of the TEC. The flattened area was likely
one inch in diameter. p28 is IITER very close to scale. 2.5 inches thick
as per Dynodon.!  See the TEC thread ,I'll calculate the angle from best available data
I need a clear picture of the cell from top to bottom if they exist to confirm length of the inner and outer tubes
The I7B were .075 x 3 to 3.5 in
As to how the electrical connections were made, without a clear picture
of the bottom of the cell, Stan could have used allthread and used nuts and washers a both ends.
So now I'll run it through a parts sieve to get Mcmaster numbers but as Bubz has so kindly pointed out, much can be purchased locally.
To avoid  cluttering up the site, send me pm's for corrections and source
suggestions and I'll add them to the lastest Demo Replicator Spreadsheet

Nice job Jim  :)
This is a very helpful tool for demo cell dimensions. 
Keep it coming,
