Thoroughly appreciate your replies guys, thanks for the welcomes :)

Right first things first.
No 3 phase. This will be my little garage that just has a standard uk power source.
However size shouldnt matter that much as it will be the only thing in there.
The only problem with the size is that i want it to be inclosed as much as possible when its in operation , perhaps some sort of flexie plastic sheet eclosure and air pump with filters - not sure yet.
But the dust from cutting carbon fibre is lethal so its either that or wear a respirator ( but thats not ideal to do 24/7 )

The size of the sprockets would be no larger than 3" to 6" diameter. Obviously the more i could do in " one run " the better.

2 Things that scare me about an old machine :

1 : The size , having to transport and move it. I don't want someone delivering it and knowing where my " mini workshop " is going to be. At the end of the day its a garage, not secure business premises.

2: An old machine scares me, as converting/modernizing one scares the hell out of me. I wanted to see if i could get an " out of the box " ready setup.

Btw not sure if rileys is still going will have to have a look !
