English wheel/ wheeling raising machine

I'll be happy to pay those 44£ as advertised

 

£2894.95 in today's money apparently.

£44 in 1939 to 2020

 

Still a bargain

 

@pressbrake1 by my comment i was suggesting definitely worth doing

 

Yes the septics know how to charge!

 

The full size will be £4500, should make £5ph machining it at that price!

 

That website has a "Lifestyle" page which is all you need to know regarding pricing...

 

Thanks PB that suggests the story I was told by an old chap living in Bishops Lydeard That they were made to do complex shapes in aero industries.
He worked for the Co.in the design office,, I met him about 40 years ago so quite feasible ,very clever with automated machine design
The one we had was this style so circles not really possible easily, It was a beast of a thing to move

 

More progress evolving pattern

 

Final cad drawing and a hand drawn idea for a smallish wheel to keep price down.
I was thinking of doing that one machined ready for someone to finish

 

I watched that ,, its nice , but not that nice.

 

i think your bottom part is too far back press break

though i must admit id consider fitting it with a motor as well serves 2 purposes than just an english wheel

Pretty sure pressbrake knows what he's making.
Looks good to me.

My fabricated one owes a fair bit to the Ranalah one I used at Mph and has a similar araingement .





Pressbrake has the skills and the equipment to do it right.

 

and some!

 

I’m a much better sheet metal worker than machinist. My designs are based on what I want and more importantly asking expert coach builder pals

 

im not questioning his fabrication skills but i think his snap point is way too far back as i think it should be more forward for the deflection rate of the english wheel most designs are based on the english wheel base been forward of the inner lift



I noted this with his pic but believe he should be more forward for pressure strength in the downward force on the english wheel

i think it could snap or create a crack on the inner arch due to downward force

 

It’s not glass it’s iron

 

How much pressure are we talking here, this can be settled pretty easy

The furthest lever point its the back arm that's where the moment will be highest

 

i can understand what your saying pressbrake but for my understanding with most designs and builds is

everything is based upon triangle based strengths

to me your break line is in line with the bottom but by coming forward a bit it would give it better strength

the other reason ive noted is for it to be lighter yet stronger when you built your straight edges also based on triangles

 

I appreciate your interest. The curve in the piece of paper has altered perspective. The section there is the same as a full size wheel but this is 15” throat
