Those are going to be challenging to build up, looks like the vertical crank arm too. Would it be possible to make an inner metal beam core, with applied moulding over the sides? If you carved the moulding in wood, make a rubber mould and cast them in epoxy or polyester resin?

Yes, quite a challenge; it will be fun to watch how you go about reproducing the beam on this amazing piece of history. How ever you choose, I'm sure that it will be as amazing as the rest of the model.

that beam is a challenge isn't it.

I was thinking about how to do that the other day ( for when I eventually do one myself) I came up with a few ideas. none of which are easy

  • make a lost foam/wax casting, either ally or brass, surface finish might not be great though
  • make it from flat stock, the outer mouldings can be wrapped around and solderd on, the bosses can be turned and then pressed/Loctite/soldered in place
  • again make it from flat stock but turn/mill the bosses in situ then add the outer moulding + central bars
  • a different combination of milling and sticking

making it all in individual parts then assembling it is probably the easiest to get right and would follow with the rest of the construction

Hi Bertie, Thanks for the ideas, I am still thinking how to go about this however trying to use bar stock and imperial and metric tooling is a challenge in itself, i may be using a certain amount of filler to get the correct profiles...........we shall see.......

Have started with the beam........drawing and getting coordinates right. a test piece for the outside beam flanged has been milled out using a 3/32 and 1/16 ball end cutters. these are really tiny so the paint will possibly hide these features !! It is quite tricky getting good photos on my camera so i take about 20 pics at all different angles and lights and try to get the best shots !

OK Willy, but what to do if the whole screen of your monitor is painted with tippex ? :lolb:

The outside flanges are milled out and sawn off. they will have to be profiled after they are soldered to the central web.....

Easy find a new monitor..........just look in the nearest skip......People in Norridge do post things on Facebook when they see them in skips !!!

Fascinating thread Willy.
Excellent work and seeing pics of the prototype is a real treat.

Hi I do have about 700 pics of this engine and what i have found is that pics of the spaces in-between are just as important as the component parts themselves, also i try to take 1st and 3rd angle projections of the parts as in drawings. it is also useful to have a ruler in the photo !!Thanks for the interest

the other side flange of the beam is made and drawings drawn for the other parts The central web detail is actually called the feather. Also the connecting rod is called the sweep rod sorry about being pedantic but like architecture every change in direction of a surface has a new name ....corbals architrave quoins purlins stile muntins  etc etc etc. Also found a big heat sink from a piece of electrical gear i was recycling and found it makes a good drilling aid.......I have also extended the side handle to make raising and lowering the headstock easier.
