  I really like following this thread, learning a lot - just wish I could work in metal. I was surprised to see you using Cold Galvanizing as an undercoat as I wouldn't have thought it would work out okay with normal paint (no knowledge just seat of the pants thinking) but apparently it does - the only place I've ever used it is on the valley flashing on my house roof.
  

  Larry I wish I could craft wood like you do. The cold gal works very well on ferrous metals.

  Nice build thread here Jim!
  
  Also nice handles for your mill .... but I do find gripping aluminum blackens my hands to some extent.
  

  Thanks Daniel, I've never found that with ali I wonder if it has something to do with grades of ali or just the end uses skin pH?

• Measuring the bolt head for length before parting off. I always use the first item made as the template for others. Probably an unorthodox method and trained engineers maybe raising their eyebrows, but it works for me and I suppose being untrained gives me freedom to just do what works for me -

  Will the tapped holes in the wood hold it or did you use t-nuts on the under side?

  Hi Carl, no nuts just the bolts nipped down onto the hardwood. They torque up very well in this wood as its extremely dense stuff.
