Now that you mentioned it I believe the .pdf I downloaded was the sevenesque version. My Champion Book has still not arrived from Amazon....Dang drone musta got lost. Documentation of parts used is a great idea. Stands to reason the more custom the build the more complex the build book.

Thanks for tips on Ozzie's Mods. Will see if I can add them to the 1/4 scale. No donor at this time. I plan on welding the front "A" arms as well and buying all the tabs and pivot points from local Dirt Track Supply. Three Linking the rear axle. Engine also TBD. Purist wants to find old Lotus Twin Cam or Ford 4. Maniac wants Small Block Ford with 8-Stack Fuel Injection. Still taking suggestions.

Hey Nick- Sweet you are already driving your Caterham. My first drive is still a build away. So to make the frame, I just downloaded a .pdf file of "The Book Frame" then divided the straight line dimensions by 4 and cut the angles as noted with a complex mitre box. And glued it together. It was fair easy given I've built a load of Radio Control planes. If you like to have one for your wall, I will build another and send it your way. My price would be $199.00 for a 1/4 scale wood frame. Interestingly the same amount of money quoted to me by Contractors Steel for the 1" x 1" steel tubing to construct the actual full size frame. Deal / Offer?

Hey all. I'm new here and at the very early stages of planning a Lo-cost Lotus 7 project. In order to be better prepared, I bought the Ron Champion book, downloaded a set of plans to study. I have a few builds behind me but never a completely scratch built car. So I got to thinking before I invest in metal and materials I wanted to better visualize how the frame assembles. Since the crux of the frame is 1" x 1" sq tube, the idea hit me that 1/4" sq basswood sticks (available at the big box store) could be used to create a 1/4 scale frame for cheap. Please note the attached pic. Still a few pieces to add boxing in the trans tunnel and engine bay, but the basics are done. http://www.usa7s.net/vb/attachment.php?attachmentid=13409&stc=1 I used the book plans and divided all the line dimensions by 4 and mitered the angles. Set up a center line on grid paper and laid plastic wrap over it so the glue wouldn't stick to the paper. For "Boot" area 1/4" dowels made for the round tubing bits. Overall it's over 2 and a half feet long and 10.5" wide. Came out pretty well and I have a much better idea of trouble spots and the assembly process. Plus when the full scale is done the 1/4 scale frame will show well with the car. The wood and a 10 gram bottle of CA type super glue cost under $20.00 and has created a valuable reference for when the steel cutting and welding starts. What do you think?
