    Best way to get lens edger without plumbing?

    My new office can get water running into the office, but there is no sewer to get water back out.

    I feel like my options if I wanted an in-house lab would be:

    1. Use a small hand edger. Not a lot of water needed, so I can handle the disposed water at the end of the day everyday. But it feels like if the job load gets heavy/complicated, I would really start to miss having an automatic lens edger. I'm guessing time will take forever, too.

    2. Use a portable outdoor sink system. I can install a portable sink with maybe a 5-gallon capacity tank underneath. The thing is, I don't know how much water the edger usually pumps out, so I don't know if 5-gallon tanks are going to cut it. If I need a couple of these 5-gallons to finish a day, then the process of filtering/drying/properly disposing the many 5-gallon tanks everyday seems like a nightmare to do after a long day.

    3. Use a dry cut edger. But I have never used them. I am expecting they are not 100% waterless, and that they are more expensive.

    It's not a big office, and I do +/- 10 jobs a day.

    May I ask for suggestions?


    EDIT: WOW!!!! Thanks everyone for the input. I've been leaning towards solution #2, but I just wasn't sure if that was a working solution. I'm putting everyone's words together to put a big 10 gallon tank with a pump from the garden supply, and try to avoid poly as much as possible, but leaving a nylon stocking attached just in case, and feel relieved that small operations rarely gets called on for.

    #2 is possible.

    We used to have a large 10 gallon tank beneath each of our 2 LE900's that re-circulated the water through a pump and filtered polycarbonate shavings with a womens nylon legging.

    You still need to dump the residual water after a while, although if your doing about 10 jobs a day, you wouldn't be doing it as frequently as you think.

    Where's the water go when you flush the toilet?
    To my understanding on dry cut is you only need water for a polished edge and then it's just a misting.

    He’s in California, the land of endless regulations. Poly is a carcinogen there ( I think your state’s prop 65?). You probably have to get some kind of hazardous waste permit. I’m sure there are hefty fines for improper disposal.


    I vote cut dry and smuggle your swarf across the border....

    If only doing 10/day, I would suggest a recirc system if you go the wet edger route. Otherwise, look for a Optronics 7EX. Versatile, cost effective, and may just fit the bill for your dry edger needs. It will drill, groove, and has multiple cutter options that you can change on the fly, including Chemistrie, and is very easy to calibrate and maintain.

    If Prop 65 is an issue, this may be overkill, but better safe than sorry. I am not in CA, but since I use alloy, I will be looking into this for my lab. https://looktopsi.com/psi/product/wa...nual-lgen-pal/
    I bend light. That is what I do.

    A recycling system will probably serve your needs. Get yourself a plastic 5 gallon pickle barrel, a small water pump from a garden supply store and some plastic tubing and you are in business. Line the barrel with a few heavy duty trash bags and when the slurry gets real nasty, put in in the back of a strangers pick-up truck after dark.

    Cost you maybe $25.00 and no hassle with Gavin Newsom. In fact, if you an find his pick-up . . . .

    Small operations typically do not pop up on the EPA's radar here in Cali, I have had several.

    However, there are filtration machines that can be used to appease such silliness.

    Better solution for poly, just don't use it. Go with Trivex if you want an impact lens. No prop 65 to deal with until they determine that trivex causes cancer.

    "Just say no to poly" sounds great in theory, but will drastically reduce your progressive availability.

    I also vote recirculating water system. I've used several, and it's quite easy to set up and clean.

    Not close to being true for FF PALs.

    I would suggest using a dry cut edger like an Optronics 7EX. Could get them relatively less expensively, and the only thing that has water on it is the sponge. It doesn't do anything with water otherwise. You would have to dump the vac though. And with yall being in California, I'm not sure how yall need to go about it. But the 7EX like previously stated, does everything and is easy to run and keep running. Just be careful with high minuses. It will eat them if not careful lol

    If omitting poly means you are restricted to FF PALs, that by definition drastically reduces your progressive availability to FF PALs. I'm not saying that's good or bad, but it is unquestionably factual.

    The best option is a water recycling system with filter.
    It is more ecological and money saver for water.
