Nice, looks like the machinist did a good job centering on the tubing for boring. Interested to see the next steps! Chopper New Year!!

I've just received a picture of the first mockup of the frame. So I'm looking forward to seeing it on the weekend to take it all in and check a few measurements. Apparently Tom took a little rake out of it just to make sure we are definitely within the 550mm rule, so we'll have to check that and how much trail we have now.

Please note this is just a mockup, and the tubing used is not what will be welded into place. The pie cuts at the bends are purely to workout angles and see how it all ties together, quickly and easily and to allow some easy adjustment. We have extra tubing to make the correct bends once the mockup dimensions are finalized.

Have you considered shortening the bottom link for regio and then putting correct length back to allow you some extra rake. You definitely want to get as much trail as you can... at least 5" .
