Hi folks,

My latest project is to build a foot powered wood working lathe but there
are a few points that I am having trouble with design wise and I would
appreciate some advice.

I'm fairly good at working wood but I have very little experience working
metal. There is, unfortunatly for me, two bits of the lathe that I think
have to be fabricated in metal - the treadle mechanism and the head / tail
stock.

I think I can probably muddle my way through a design for the head / tail
stock (I was thinking of using a drill chuck or something similar) but the
treadle mechanism has me stumped.

The current plan was to have something like this (excuse the bad art)

--B----| |--
--B----| |--
|A|
| |
-|D|-----| |--
-|D|-----| |--
| | | |
|C|
| |
Z Z
| |
--E---------------F------
------------------F------

That's a terrible drawing sorry )

A = Crank ~5cm
B = Flywheel Axle
C = Other Crank Bit ~30cm (Sorry don't know the correct names)
D = Bearing (I hope)
E = Another Bearing
F = Treadle Plate (it's pivotted BTW)
Z = Shows this bar is much longer than A

Can you buy this sort of set up? If so where as google has let me down. If
not how would you go about producing this? I have considered butchering a
couple of bicycle pedles but that feels like a really bad solution.

Many Thanks,

Graham
