do it as well as you can,but learn to do it better
Cheers Routy 
if you're doing new plates, holing them as a pair will help dramatically
be sure to get the centres right and your pins parallel to each other and square to the cheeks .... horizontally and vertically
if you haven't got anything suitable to use as a substantial spacer/packer, tack a couple of braces across the tops, if doing loose pins ....
whilst stitching up and firming all welds
if they're fixed pins, some substantial stitches of the pins to cheeks'll keep them spaced and in place , but good stitches and sequential welding will keep things in place .... if you do have a good packer, even better .....
the thin card in these is to assist in getting the packer back out and give me an extra half mil on the tolerance
when you're happy everything's right ... secure the pins .... and burn it all in

shout if I can help in any way
