There was a similar set of drawings on the Facebook Lotus Historic Register.  A contributor on Locost USA downloaded a similar set from Pat Prince, who dissected a Series 2  frame, and took as many measurements as he could.  Pat Prince took over the work of DSK when the owners folded the company. I'll attach the files here and hope that they download?  With thanks and recognition of the locost usa forum. W

Scott.

 

As you know, I'm as vintage as the Lotus Seven, so I did wonder if these pdfs would work!  I can send them to your email if you want them? W.

That would be very helpful.  Josh beat me to these by a few hours.  But I'm glad he has them as he's putting together a Seven museum. They will be very nice displayed somewhere.  Im thinking of sending him the S4 model I got from you.

I've also seen this set before, but it always seems to missing Sheet 2. Has anyone seen it, or is it classified...?

Not classified. Just hard to find...and read.

Cool! My life is complete. Well, at least my drawing set is.

@anduril3019 and @skou.  I wondered where page 2 was, as I could never find it, guessing that the person who posted the drawings had omitted page 2 in error.  I also found a set of drawings in 8.5" x 11" posted on the web courtesy of a company called 'Fisher and Paykel Ltd', (Laundry Division!?) for a Lotus Seven Series 3, metric measurements, with top and bottom front wishbones looking more like a Caterham or perhaps a Locost?  

 

George Cushing also provided a drawing for a Seven Series 2 on his site, and his Imperial measurements very closely match up with the ones I took from my old Universal Radiator frame.

 

There are also a couple of pages of drawings on the Locost site with no credit provided for the person who drew them. They show all of the brackets required on a Seven frame, along with the necessary radius bends for the frame members, but again metric measurements.  

 

Just in the miscellaneous (useless?) information category, but  in the mid 1980s,  Lotus - in their official club magazine - were offering factory drawings for sale of a number of their sports and racing cars (I can't remember which cars, but from the Lotus 20 possibly up to the Lotus 77?  John Donohoe may still have the copy of the magazine I sent to him?)  The Seven was not included because Caterham had purchased the rights to the car (Series 3 and 4) in 1973.  Even the 37 and the 7X were not included as the 37 frame would be almost identical to a Series 2/3 frame, and the 7X was a design by Mike Pilbeam, head draughtsman/designer of Lotus at the time, with the car based on a Series 4 with considerable modifications. Mike Pilbeam has retained the drawings in his personal collection. He was very helpful describing the frame, but could not locate the drawings when I inquired a few years ago. When it was realized by Lotus Legal Department that unlawful copies of the drawings could be reproduced, Lotus withdrew the offer on advice from their legal department.  I also read in the magazine about a purchaser who complained about the cost of postage to send the drawings in a mailing tube to his U.K. address (12 shillings and sixpence at the time I seem to recall - probably less than $2.00 U.S. in today's money?).  Lotus promptly refunded his payment and the drawings were not advertised again as far as I can determine.  The Lotus Club magazines I had were published in 1983 and 1984, as one included the commemoration of Colin Chapman (following his death in December 1982), and Lotus at the 1983 Silverstone GP, when a number of different models of Lotus Cars  completed a circuit of the track prior to the G.P. I was fortunate to obtain a pit pass at this race, and took photos of many of the different Lotus Models lined up at the end of the paddock.  W.
