And so the saga of the walnut washer continues. Last Monday, 121kg of<br>
galvanised steel arrived - 24m of 40x40 2mm wall, 16m of 40x40 3mm wall<br>
and 8m of 25x25 2.5mm wall square tube. I managed to scrounge up half a<br>
metre of 50x50 to fit inside the brush, mount the axle and fit the drawer<br>
bar coupling from a local company.<br>
<br>
With the addition of an old trailer axle, it now looks like this.<br>

<br>
Three things left to do<br>
* mount the controller in such a way as it can be easily removed to keep<br>
out of the weather<br>
* install the plywood base and pond liner for the 'sump' that supplies<br>
the washing water<br>
* build the drive for the drum.<br>
<br>
Its the last item I need ideas on how to reduce cost.<br>
<br>
I've already determined that the way to go is to use a toothed belt<br>
'in-side-out' on the drum so it becomes a large cog, being driven via<br>
toothed belt from a cog on the motor shaft. Adding the bits up I'm not<br>
going to get much change out of $500 for the 2 belts and the cog if I buy<br>
new from somewhere like i-trans.<br>
<br>
Does anyone know where I can get the same sorts of bit second hand (i.e.<br>
cheaper) - the cog will require adapting for the correct fit onto the<br>
motor anyway and the drum is 560mm diameter - longer than most car belts<br>
as far as I know.<br>
<br>
So - where do I get a couple of long belts?<br>
<br>
Cheers<br>
