    Thanks Justin. I am tasked with aligning and servicing 3 guild raytechs. (North York Faceting Guild)
    I'll probably learn the hardcore full alignment methods later. (laps, platen, lily pad, foot left to right, foot front to back)
    But your methods helped right NOW.
    First I learned the cheaters range of travel so I could properly zero it. For the feet I adjusted the one slightly since it wasn't zeroed. Then used a 6" rule with a slide to measure both. The other was off alot. Made them the same. Locked them into place. Then loosened the grub screws in the knobs, turned the knobs to zero and tightened them back up. That gives me a quick way to get back to whatever zero I just established. This was an after midnight quick thing. I'll want to dop a stone and do it optically like you suggest. Looking forwards to when you do a vid of adjusting the front to back. Someone did one but I'm always interested in your methods. Keep up the great work. And I hope sometime you could show how to remove and install the platen bearing for the Raytech.
    I'm also planning to 'touch up' a typemetal, copper and tin lap. I'd rather tackle myself then go to a machine shop. I may have a thin used lapidary saw blade somewhere. If I don't I could make a 'dressing stick' with a piece of glass, 600 grit wet/dry sandpaper, maybe a handle. Use the machine to spin the lap, and the dressing stick to remove the yuck, remove embedded grit and lightly resurface the lap. Check for leftover grit with a razor blade from both directions. Finish with finer grit sandpaper, steel wool, metal polish. (unless want light a slight scratchy surface).
    Do you have a preferred method for cleaning cutting laps or checking if they're too worn to use?

      I have a video where I skim a polishing lap called finishing lost treasure. It’s in my laps playlist. That might be helpful for your polishing laps. If it needs a lot of skimming though I would take it to a lathe as you’re going to have a hard time taking a lot off the top.

    Thank you for this great tutorial video.
    Do you have also made a video for balancing the first (middle) part of the Raytech Shaw Handpiece?

    You have convinced me that mast machines are not the only top notch formats for faceting and I am super interested in trying one out!
    By the way this is Pinebox from Facebook and my account is restricted.
    My apologies for not getting back with you.

    Thank you.... our Lapidary class at Yavapai College in Prescott, Arizona recently acquired two Raytech Shaw faceting machines from another YC branch.... the machines seem to be in good condition, though they have been locked away... and or lost since the mid 1980's.... what a great find !! However, we are all newbies to the complex world of faceting.... so, your quick video has shed some light on a wee portion of the use of the hand piece. Thank you again for the video !! I'm hoping to find more info, if you have any ideas please feel free to bombard my brain with info, it would/will be greatly appreciated. My best to you.... where your mask and stay safe !! Jami

      Thanks and congrats on the find. This Handpiece came from a similar situation. A cutting factory in bangkok from the early 90s closed and put everything into storage. In 2019 they wanted to clean the storage and I got invited to come check it out and take a select few pieces. To my surprise there were a dozen Raytech Handpieces from the late 80s (hence the color), still in the box with instruction manuals. Never opened until I got there. Very cool find. I’ll post any info as I get it.

    Thanks for taking the time to show how you tram the handpiece. Very nicely done. Have a couple of Raytech machines that I presume I should be able to do the same way. What type machine are you using and are/where they available for resale? The next time I do any faceting with the Raytech I'll see if I can get the handpiece trammed. What procedure would be necessary to tram/balance the platform if necessary. Thank you very much!

      I’m using a Handpiece machine from sterling from Sri Lanka. We use pretty much the same technique to balance the 3 feet. As for the platform... hmmm I have not messed with that. I think it doesn’t usually get out of alignment but if so maybe I’m not the best person to ask. Usually balancing the Handpiece will take care of any imbalance between the lap and the Handpiece plate. Good luck

    That's a great hand piece as most of our customers says. But requires few modifications.

    • @JustinKPrim
      @JustinKPrim  Год назад +2

      Sorry no. I’m left handed and I hold the Handpiece in my right hand and control the height control with my left. No problem. This way is better because then your left hand is always free to take notes or pick up your loupe.

    Hello. What kind of problems will occur if the machine is not flat?

    • @JustinKPrim
      @JustinKPrim  3 года назад

      If its not balance left to right, the girdle won't be straight. On an emerald cut for example, the first girdle facet and the last girdle facet won't match up. One will be too high or too low. If the front foot isn't balanced, your table will be at an angle instead of perfect on 0 degrees

      @@nurettinburak4061 facetrons arms don’t come off the mast. The Handpiece is adding a variable at the contact point of the Handpiece meeting the riser plate. That variable doesn’t exist in mast machine. However the mast user has to make sure that their table adapter actually flat at 0 degrees which is similar to balancing the front foot. On My old machine, the angle had to be at 1.6 degrees for the table adapter to be flat.
