Im using 1.6mm Ali my biggest challenge was how to bend it, the plans said to just cut and pop rivet every thing but I thought Id try and bend up a box. So I made a sheet metal brake but it was a bit flimsy but I made it work ?

Looking the goods. The rig you made to fold the sheets is a great idea

thanks found it on youtube.
I think I'll make a bigger version and weld it.
 
It looks like you have quite an aggressive angle on the riffles. I would run 90deg for the first few riffles, it helps with the material flow. I would also recommend changing the riffle height to 15mm. This suggestion was made to me after I built mine. I made the change and it worked better.

Also, if you haven't done so already you'll need to order some Keene dry blower cloth from Reeds Prospecting in WA. It can take a while to arrive after ordering.

Ok thanks falcon Ill make some changes on the weekend I have the cloth from Reeds on the way, whats the best way to attach it to the aluminium?
I also need to find something for the classifier.
 
Selley's liquid nails works well. Much easier than using a contact adhesive. Smear a light coat on the aluminium and the place the cloth over. Then just run your fingers all around and it should hold in place with no tape or anything
 
Hi Max. Just wondering how the dry blower project is going?
