Thank you both for tuning in.  I would guess that this particular model is not the most complex of Jan's creations but that doesn't mean, in any way, that it does not require constant attention to the little details.  This is my 5th plan of Dutchy's with No 6,  the VW bus,  still waiting on my desk.  I think Jan does great work and every plan gives us something new to learn and create.   I will say that IF I was not as far into this as I am, I would fabricate the engine part completely differently using additional parts and not use a solid block of wood.  My reasoning is that I would like to add engine cowling vents along the side where they exist on original models of the AC6.  I thought I could use my S1 laser to do it since it will carve bowls and such but the incline is too steep for the laser to traverse.  I've spent time considering building a router jig but no good solution comes to mind.  So, I've reconciled "no vents" this time around.
