Hi All Back at work after lots of other stuff to do ..and i have made some drawings of some of the components . The main bearings have been drawn and then adjusted to look right as I have not been able to gain access to measure everything !!. I have drawn it out on a piece of A3  using inches but there was not enough room to draw it full size so it is a 1/4 full size. I have then drawn a line using the mm rule to measure the 24 inches at an angle ( in blue) ..and then used this to measure accurately all the dimensions to make the parts. So using the perspex just one bearing block was made without the brasses. Looking at the photos the brass bearings are quite involved using 5 separate parts .. also there is no top part to enclose the whole dimension ?? However there is a lot of weight with the two flywheels to keep them in place...  There's also an unusual top cap arrangement that has one end attached with  3 Allen screws to keep the cap in one piece ..?? I dont know if this is the original  or if it is a later repair ?? The engine was made in 1898 and I don't know when Allen screws were invented and first used ?? This can be seen in the last photo

Never seen a bearing arrangement like that!  Looks like they are all like that in your earlier pictures, so it was not a one-off repair on one bearing. Huh.

High Chris, yes it is quite unusual  ?? and I was wondering if the top part of the bearing is missing ??   also this is the video of our recent club exhibition here in Norwich   more drawings and the bearing parts to follow soon....

So the bearing parts have been made from different colours of perspex and I like to do this to work out the best way to manufacture them in metal..I have drawn out how the parts fit with an isometric to make it clearer . Rather than have a top and bottom brass as is more common it would appear that the crankshaft with the flywheels attached were hoisted into the bearing blocks and then the side pieces were put in afterwards and then pushed sideways and the spacer inserted and then adjusted with the side bolts ..?!!!

Those bearing parts go together a lot like a multi-piece steel mould, interesting.

Hi Willy, the nice 3-D modelling continues!

Also, thanks for showing the video of your club exhibition.  Did you also take any still shots of some of the engines?
