Jaykay, cheers
Need to get heddle first I'd guess, and I assume the rollers would need ratchets on them, and a beater thingy
Mind at the end of the day I'm coverting one like yours with a stand, I'll have to check my savings account and open the shop a bit later to earn a couple more pounds
Seriously though, I've got a big bit of mounting board and have started drawing it up, using a I beam design to strengthen he sides, it won't last but if it works it'll do as a template for something a bit more wooden
