That English Wheel looks a very professional build.
How did you come up with the design?
Paul
The frame stiffness, panel size to be made and space to work the panel are all important parameters. The frame stiffness index values were obtained using Richard Ferguson spreadsheet. The adjuster is based upon Kerry Pinkerton design (Imperial Wheeling Machines). I wanted a removal lower arm so I could change the angle if required or the wheel size. I have included a few more pictures.How did you come up with the design?

Again, impressive engineering and research.
I am curious as to why modern wheeling machines are designed differently to the older machines where the top wheel is carried on a shaft that runs to the rear of the arc of the frame (e.g. F W Edwards)?
Clearly it would require substantial shaft strength and a good large bearing but does it have a design value when using the wheel?
I know our forefathers were inclined to over engineer everything, but is the design a result of not being able to arc weld?

Hi Paul, at the end of the day it’s the force you can apply the metal to be formed. Lots of fabricated (cheap) wheels have soft frames so the metal is slow to form (think of the frame as a big spring). You also have to consider whether to use contact flats or true radius anvils and what width and diameter you will use. By building your own machine you can dictate your own specification. My wheel has a 850mm throat which mean I can form a panel of 1600mm and that big if it’s just you.I am curious as to why modern wheeling machines are designed differently to the older machines where the top wheel is carried on a shaft that runs to the rear of the arc of the frame (e.g. F W Edwards)?

Hi Andy
I like the idea of using a wheeling machine from the same era as the chassis or engine and they seem to make good investments too (being an old git I need to think about these things).
If I do end up making one it is bound to be over engineered and bloo*y heavy. An example is my welding table. 2m x 1m and over 0.5 tonnes in weight!!!!
Probably not look as good as yours though.

Ok from the same era, so I now expect Thor to be built from 1050H14 ally using gas to weld the panel sections. Don’t even think of using Tig or Mig.I like the idea of using a wheeling machine from the same era as the chassis or engine and they seem to make good investments too (being an old git I need to think about these things).
