Hi "C", thanks , I do have a pair of Eyecrometers that are fortunately a matching pair ?!!! Both Conrods are now made and the crosshead parts now need to be matched up to the piston rod. This is where the  " FITTER " comes in and there is enough  meat on the top of the Conrod to create a good fit ...

The fitting for the crosshead part has now been sawn and filed up and has been assembled to the standard to check for the clearances. these seam to look ok and now to calculate the crosshead pin for the correct piston travel.

Hi "C" thanks and more pics of the procedure for marking out the con rod prior to sawing out the slot  ... the slot at the top of the rod follows the contour of the bottom flange. this is marked out using the heavy steel block and a magnet to hold the small square against the top of the conrod. also a key seat rule  ( some brass angle ) is used to scribe the lines for the hacksaw to follow......

Hello Willy,

I'm glad that you still work a lot with the saw and file.
Traditional handcraft and I think it goes well with model steam engines.


Best regards Michael

Hi Achim and Michael thanks for the comments and I do find that as filing is quite a slow process one can  keep track of what is happening with the parts  !! Both condos have been made and coupled up to the crossheads and have been connected to the standards ..quite a bit of fitting has been done to get everything running true and the motion is running freely.

The next job is the eccentrics and the bronze eccentric castings are drilled in one piece with the 6BA drill  and then sawn apart and one of the top holes is drilled the clearance size and then the two halves are joined together using the tapping drill to hold the two halves correctly in position and then tapped. this ensures that the two halves will stay correctly positioned when bored out to the 5/8ths dimension.

I have bored and faced the bronze eccentric straps   using a small independent 4 jar chuck with a perspex backing piece to give clearance for the facing .. so next job is the eccentrics them selves ...  also someone has shown me this item ?? he does not know what it is or used for ... the diameter is about 1 1/2" so could be a gauge to measure the length of some sting ??!!! as it is coiled around it up the spiral !!  any ideas ?

Te eccentrics have been made ..first the stock has been tried at the end to get a good fit for the strap  and this dimension is then used to turn the actual slot for it. the stock is then removed and two holes drilled and tapped to attach to the 1/4 " Stock to attach to the lathe to turn down the eccentric part for the crankshaft adjustment grub screw.  Also the brass item is a fuze from an artillery shell ??

Hello Willy,

It looks good how you build the eccentrics.
It could actually be a detonator from a grenade. There are similar pictures on the internet and there seem to be people who collect things like this.

Somehow I don't  think I'd fancy machining something that may have started out life as a detonator or fuse.
Don't think I'd fancy making a collection of them either.

In my working life I had dealings with explosives for rock blasting, and that was enough for me. Especially when 3 tons of commercial explosive went off when I wasn't expecting it to.
