No problem to glue and bolt machined alu part to the slot. Part can have M3 or M4 thread for mast-ram. There are thumbwheels with M3 thread and 12 mm wheel diameter at the workshop. It is a perfect fit for that part. Also U- shaped wire could be possible to put into this part. I don't yet have long enough twist drills to drill those holes for M3 threads. Regular jobber drills from hardware store are too short for this job. Have to buy some 95 mm long 2.5 mm drills at the next week. It took about two hours to design, program and machine that first prototype part from aluminium. It's so fast process to make these or slightly modified versions from aluminium that I think it is the right manufacturing method. Glassfiber lamination is so slow process that at these days nobody has time to do it :) Can you publish Pikanto deck layout drawing to this blog?

Can the same alu-part have an M4 thread length-wise for the mast-ram? The no3 jib needs to be sheeted from just where the foredeck starts. Can we attach a U-shaped wire for the no3 sheeting-point?

It's a simple "Fork" design. I think it looks pretty good, at least on grey boat! If you come to the workshop tomorrow you can take pictures of it, I did not have my camera with me today. Jari P.S I have machined nine balsa cores for rudders during this week. First balsacore rudder with carbon axle was laminated yesterday and 5 hours post cure for it was made today.
