Friction ?
  • After getting basic gears and frame together on Primus i had trouble getting it to run . Looked everywhere to ensure everything ran free and could easily pass blow test. Left on one side as thought i was beaten and got on with a few other projects. This morning i took it out to have another look and realised it was same point it slowed noticeably on the escapement as if running out of energy yet no friction obvious. The answer was the escapement wheel was out of balance and so a small lead bb taped to balance the wheel did the trick.
    Any other wheel i don't think would matter but very little force can slow or stop this one.
    The imbalance is due to the cogs being solid wood hand made so not as accurate as cnc cogs.
    Still lots to do yet but happy now at least it runs
