Thanks for all your help - yes I am always happy to work these things out myself, especially when people are helping for free.

If you are ever in England you are welcome to a few bottles of cider,...

Thanks Kelly :-D



Ye I worked that out, was looking at fourm threads originally. But the good news is I worked it out. Got a slightly lower number than Kelly, but was still over 30 tons per...

Thanks - I was trying to work out the materials strength - how strong it is if it was being pulled at each end type thing. 32 tons sounded more than expected

Is the weight important to calculating...

I could not find any threads about that.

I did the following maths.

Area in mm^2 is 314.15mm^2 per bar (10^2xpie)

= 0.486933474 square inches inches

870 Nmm2 = 126,200psi

Hi,

I have been trying (and failing) to work out how much a threaded rod can take load wise.

It is m20 8.8 High Tensile Strength and has a tensile strength of 870 Newton Metres (870 N/mm2). The...

I am trying to calculate how many tons each bar would be able to take if I brought some high tensile m20.

m20 (8.8) 1.5m span tensile strength 870 N/mm2

m20 (10.0) 1.5m span tensile strenth...

Cheers



A round file, filing 5mm off 16 holes - not sure there would be any cider left by the time I had finished! Surely that would take days?

Thanks for your replies - I think what I will do is go for a 12mm sheet then if need be weld some additional supports on. I will let you know how much it bends (if any!).

I will also ask for...

Thanks for your detailed reply.

I know the RSJs will cope with the pressure upgrade, theoretically so should the uprights, not sure if it is something I want to risk though. The base is very...

Hi All,

I have recently built a cider press (pictured and videoed below). It has had one year of operation and was successful however whatever we put between the jack and the apples...
