      I made this video for my level three apprentices it basically contains everything that they will need to write their C of Q or red seal ministry test
      Thank you again

    Sampling length on my SJ-210 shows in terms of Lambda C .1 and the travel distance is nearly .500" Shouldn't it be Lambda C .5?

    Great video. I just scored a surftest 210. Im checking finish on everything. Im curious about the standard. It says 117. Im picturing a 125 finish, which is rough. What id consider a saw cut finish. This standard looks alot better than that. So what do i have wrong?

    • @raysfix

      These pieces of equipment are extremely sensitive and can go out of calibration easy
      If you know someone who has the same unit as you do a side-by-side comparison using the same test piece should give you the same results
      If you have access to another master sample try using that to calibrate the unit

    That is helpful to me.
    what are your thoughts on measuring Lapped surface. More of a flatness spec vs roughness I think.
    I just run an indicator across the part on a granite stone to check, sampling edges and middle and fishing around.
    Surface finish is in the weeds for this I think when indicator is less than 1/10 of a thou or better
    Probably a dumb question, had not thought about it.

    • @shopandmath
      @shopandmath  Před 3 lety +1

      if its for flatness ?
      CMM with a contactless prob
      or try using Optical Flats (most high end inspection labs have them)
      you could call your local university and ask if they have a Lasermike
      It uses a helium-neon laser beam to scan the surfaces

    • @johnm840
      @johnm840 Před 3 lety

      @@shopandmath Optical flats are great. you see so much once you learn to read them.
      Small deviations not something I need to do, but an interesting topic. Tom Lipton videos has me thinking beyond just 1/2 thou range. +/- .005 my typical range and I use those finish samples for reference at times. Thanks for the videos and topics you cover.

    So I have perpendicular symbol with a .02 after the symbol. are they call the machine marks to be perpendicular with in .02 of the surface?

    Hello Sir, i was wondering is there a possibility to measure the parameter Rmr and Rsk on this device? it would be very helpfull thanks a lot!

    • @raysfix
      @raysfix Před rokem +1

      It is possible to check the perimeter it needs to be a non-sledded style probe
      It may require a holding fixture

    Do you know where i can buy these Surface roughness metal plates ?

    • @shopandmath
      @shopandmath  Před 3 lety

      at any machine shop supply
      amazon has them
      I got mine for almost nothing (used from buying old tools)
