    1/4 inch plexi for 16x20 washer?

    I am making a 16x20 vertical print washer that will encroach on 2000 cubic inches of water and am worried that 1/4 inch plexi wont be rigid enough. I'm welding the seams so I'm not really concerned there but it seems like it might deform alot when full. If anyone has a 16x20 could you measure the tank thickness? Thanks very much

    My 16x20 has 3/8" plexi as well, but you could put a small strip at the top to add strength if needed. My 20x24 has a 3/8 by 1" piece perpendicular near the top to add rigidity.
    Both of mine are zone VI but the place that made them was local in Madison, WI. I went over and got sratch & dent models for a discount.

    My first "self built" 16X20 washer used 1/4 inch acrylic for the walls. I never had a leak in it over tweny years of use. My current Zone VI is what others have said.

    One could get by with 1/4 inch acrylic if it is designed properly. I believe that one could be built lighter and less expensively then using 3/8 inch acrylic if one designed stiffeners into the side walls and used 1/4 inch material.

    You should be guided by your own beliefs on this.

    As with many things, ultimately impatience rules design. I cant find 3/8 material locally and have 1/4 on hand, so it seems my decision has been made for me. Thanks for the suggestions and Donald that certainly helps to know yours was good for 20+ years. I'll post some pictures when it's done.

    You could use one of those big rubbermaid bins as your container. Those things are industructable. I did it for an 8x10 washer.

    Hi,
    ...any ideas on where one might obtain plexi at a modest cost. (local supplier is TAP) When I looked into this the cost of material made the price of commercially available units seem good value.

    My washer is stainless steel, like Ansel Adams used.
