I need a small metal piece to restore a tagalong tandem trailer trike to roadworthiness and two grandchildren to what they see as their natural position in the grand scheme of being. Two Members have helped me out in the past by fabricating similar bits, and I'd be very grateful for any offers, or failing that, suggestions for commercial suppliers. I can supply a sketch with measurements, but not a CAD file. I'd be very happy to pay, or donate to charity, or whatever you'd like. Thanks in advance Jonathan
