Ah, have not seen a reference to a planimeter in a long time. I have one that I use for boat hull design, got it for calculating areas and displacements before the days of software design tools on home computers. Really neat tools, another one where someone had a brilliant moment of thought to design them.

Hi 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

Great job you are doing with this unique early engine, industrial archaeology and model engineering, inspiring thread !
I made an ETW's "Vulcan " beam engine in the past, I see now that I should have done the square nuts as in the plan...

Hear is the video showing the workings of the Electrically heated steam engine, also the more detailed version that appeared in EIM a few years ago

I have had to make some bolts different lengths so i have had to make this simple device.......it was some lateral thinking when someone wanted a lightweight bowden cable cutter when cycling to Japan !! it is made from silver steal and at the moment is in its unhardened state it also works well on rivets.......I have not seen this before in my ME mags and i am sure someone else has also come up with this idea.......The problem with most cable cutters is that the shears move apart and don't cut ,however with this device the shear faces can not separate....

More work on the Radius reach rods .........I have used square stock as this is easier to hold in the vice when filing up. I have also turned the ends up round and support them in a brass bush in the tailstock chuck, i find this easier to hold work as i have found when using a centre this can heat up ,expanding the rod so causing the headstock to jam up and slow down ,also the stock is held really rigidly preventing distortion when turning down. The rod end that attaches to the support bracket is made in two parts and so to make it easier to file and drill accurately the parts are silver soldered together ,filed and drilled then reheated and parted. ...................

The lower air pump crosshead has been made and the parts silver soldered together. The motion work is quite complicated and will have to be very carefully measured up so all the parts fit. !! I am having to make the parts not quite to the drawings so they will actually fit and work, so this part had to be taken apart and re dimensioned.

The air pump straps are made next. they are made from square stock so when the holes are drilled using the brass template, they are kept in correct alignment. Once drilled they are filed to shape....

Thats a clever way to do it! Looking good.


What is the purpose of the air pump in the engine?
