Nice Willy! Love the planimeter!....DaveHi dave , yes ,I got it for £20 at a flea market as the chap did not know what it was !! Oldschool stuff is good .......i prefer to say Olds cool though. As experts with using this tool, can one use it in reverse to plan out a certain area that you may require ??
Reverse plotting out an area wouldn't really work, you could draw a number of curved areas and measure to find what they are by trial and error though.thanks for the info... I have now had to remake the motion hanger pins as the first ones that were drilled and tapped for 10BA broke off because there was not enough meat on them, new ones have been made using 12 BA bolts and, because the accuracy is not that critical i have used a heavy duty automatic drill chuck. this is used, as, being quick release the job doesn't take too long when removing and installing the rods
