    Stick out tongue Horizon II edger help

    I just started working for an OD who purchased some lab equipment and wants me to try my hand at edging lenses. I have been in the business since 1995 but have never manufactured lenses before. As I was reading the manual for the edger I noticed a feature that allows the operator to make a pattern from a lens; has anyone used this feature before and if so are you willing to give me more in depth instruction than the manual provides?

    Thanks

    Just bring up the job # and set the edger to rimless. (You should have a block that fits patterns that you have been using to set your axis). Hit the go button.

    If it's a Horizon II, there isn't a job number. There should be a brass block with a cross on the convex side and holes on the other side that match up to the pins on the pattern side of the machine. To make a pattern, mark the 180 on the demo lens and then use a box-O-graph to find the center of the target lens. Use a leap pad to block the lens, on axis, to the cross side of the brass block. Use the pattern adapter (looks like a leap pad with 2 pins on the back) to mount a pattern blank where the uncut lens normally goes. Adjust your sizing (usually 36.5, I believe) and run as a rimless plastic lens.

    Be careful when cleaning the swarf from the newly created pattern, as any nicks or dips in the pattern will be evident when you cut a lens.

    Hope this helps. It's been about 10 years since I've used this machine.

    A lack of planning on your part DOES NOT constitute an emergency on mine!

    Bob, you are spot on except the sizing needs to be set at 38.5 instead of 36.5 for a rimless cut. This part ("looks like a leap pad with 2 pins on the back") should actually be leap block and not leap pad but other than that I couldn't have said it better myself. Great explaination!

    You have to carefully observe the lens from which you're making the pattern. Especially with lenses much wider than deep, you can sometimes see the demo lens flexing as the machine is following its curves. This means the resultant pattern won't be quite right.

    I think it's usually better to make the pattern by hand. I think it would better still for the OD to call ol' Leo Hadley at VSI and buy a Santinelli 7070 for $13000. You'll get much better lenses and use much, much less time doing your lab work.

    Pattern from a lens adaptor?

    Hi all - I'm a teacher in a HS in Rochester NY. We're working on teaching students to make glasses and we recently purchased 3 horizon 2 edgers (i'm of the thought that it is better to teach manual and then they can go work on the automatic). I desperately need to find 1 or 2 brass adaptors for the pattern from a lens capability. Any suggestions?
    Thanks!

    Confused Question on type of blocking to use

    We have a Horizon II Edger as well, wanting to get it up and running as a back up to our Kappa Edger (Since we keep breaking doors all the time), My question is what type of blocks are use to block the lenses, I understand you need the Leap blocking pads, which we use anyway, but what blocks to use, the manufacture doesn't have a clue.

    What Fezz said. The chuck is interchangable, and manufacturer won't know what the person you bought it from had on there. Best thing you can do since this is a backup is use the same chuck as what's on the kappa. The following links will give you an idea of what you need.
