    Re: model railroads

    I found another interesting clip. I used to have a few N-scale Japanese bullet trains. My favorites were the Nozomi 500 (the real 500 in Japan tops out at just under 200 mph).

  3. Re: epoxy ruining band saw blades, jointers knives, router bits,

    Most epoxy starts to soften at about 140 degrees F, which isn't very high. It could be that someone, sometime, cut something that was epoxy coated and gummed up his blades so he adopted a blanket...
  4. Re: Trimaran, sail/row-paddle/cruise-race, for R2AK & minimalist cruising

    Yes, but there is an obvious overbend wrinkle (yes, that's a real thing that sailmakers attempt to avoid when designing sails to fit curved masts) in the mainsail. I don't think most sailors have any...

    Luckily, it seems to dissipate, so the gun rack doesn't smell for long, but you do want to get the rags and patches out of the house and in the garbage ASAP.
