Good job, any heads up for me regarding the HS, because I just started it now

     When you countersink the spars to allow for the skin dimples, error on the side of too deep (ever so slightly, vs too shallow), so the skin seats completely into the depression and is not held apart when rivetting. 
 
  On the nose ribs, bend the very front corner inward to avoid excess pressure on the skin when you finally seat the inspars and ribs into the skin.
 
  On the wood jigs to hold the assembly, cover all the surfaces that will contact metal with duct tape as a cusion, and if you error on cutting the wood, make them too big. They are not needed for detail fitting, the match drilling does that, just to hold the thing up while  you work.
 
  Label all the parts for "top" or "Bottom" and left and right. after you match drill, then disaasemble, there are a lot of parts. Number all the ribs in an order that makes sense to make reassembly a no brainer.  It seems obvious, but often you will have the HS upside down and top is now down...... it only matters for a few holes that you will skip rivetting and dimpling on the top side, and for the attach brackets. BUY the CNC attach barckets (and the weldment nuts for the elevator trim)  from Silverbullet..... his brother is on this network, ad the e-mail address may be in the archives, very nice parts and priced fairly.
 
  Get started, there are a lot of rivets.......  fun to have a BIG part done.

Steve,
 
Nice explanation.  I agree with it all.  Can I have permission to use this on my web site, proper reference being given?  Probably put it under helpful hints for the HS.
