• RC Running or Sliding Fits
  
• LC Locational Fits
  
• LT Transitional Clearance or Interference Fits
  
• LN Locational Interference Fits
  
• FN Force or Shrink Fits
  

Each fit has a class associated with it to determine the allowance which is applied to the hole and the shaft. I believe it's done a bit differently in the metric world, but the outcome is the same...

Hi Tom - I revisited these two posts of yours to look a little further into tolerances and I struck me as being a good topic for one (or more) of your videos. I don't recall seeing any for a moment (either your camera is frozen solid or you have run out of topics!).

That would be a good topic Darren. I did consider it at one point, but forgot to add it to my list. Consider it added now.

I'm still cranking the videos out at a rate of 1-2 a week. The latest ones have been project tutorials on for the carriage stop, with the most recent being how to cut the divisions on the thimble using the dividing head. Then there was the band saw brazing video a couple weeks back.

Everything else may be frozen around here, but the camera is still rolling.
