Not into knives but thought someone may be interested in my grinder building it will take a 2.4 metre belt.
I started this a few weeks ago and if there is any interest I will post more as I proceed.

Looks cool so far, however my inner blacksmith cringes at seeing a nice swage block being used as a stand underneath where you're pouring your melted aluminum and the poor anvil laying on it's side looking like it's ready to be abused >_<

No more than anyone else, just too far to go and get bits

Yeah, yeehah engineering mate. I would love to come to the USA to work, has NASA got any vacancies?:D

I got a bit more done today so i will post some more pics during the week.
 
so you started out making your own aluminum castings to machine the pulleys from. Nice recycling and basic thinking. Love it. Now please stand the anvil upright and fix it to the top of a stump when you use it to crush and smash your salvage. Please, some day you or someone will be glad it is still in good shape. Good anvils are slowly going the way of the wooden wagon wheel.
 
G'day mate, did you turn the idler wheels with a crown? thats the mistake i made when building my grinder, (the tracking wheel is machined out of a straight piece of 6160 so the belt doesn't track quite right) will be interested to see your progress, keep posting pics.:)
 
Got a bit more done today. As you can tell I have used aluminum for the platen body, I hope it will be strong enough. I need to now make the backing/ rub plates has anyone got any clues to the best way to do this, do I just use steel / aluminum angle or should I use some other material?

Take a peiace of angle iron, and mill one side perfectly flat(or atleast close), then polish that surface pretty good.
 
You can also get a ceramic plate to bond to the steel platen to give you a smoother surface for the belt to slide over. Your project is looking way good. and you are obviously not a newbe at metal work.
 
Man, that is slicker n snot!!! It must be super satisfying being able to cast your own parts!!!
 
Does anyone have any clues as to using some sort of composite graphite plate for the backing/ rub plate.
 
Graphite would wear away very quickly and would not stay flat very long. Most of us use ceramic and I use hardened 01 for a platten backing.
 
Yesterday I molded and lathed up the disc attachment, I was quite proud of my effort it turned out well (the pun unintended)
