RE: [PSUBS-MAILIST] Great Update on the old K-250 sub in Sandpoint

Fantastic, It's nice to know we have good options. Are these view ports just the glass or the glass and the metal framework? I'm thinking I might like to use polycarbonate for a number of reasons. But I need to do a list of pros and cons compared to acrylic. There is a number of different brands and types in those brands that most have different advantages to compare as well. It's like going to school. So you could say I need to be schooled. : )'

Hi Brent,

I'm currently in talks with a manufacturer of certified ASME PVHO view ports to offer these through PSUBS. I have no idea what they would cost, but it's an option you might consider if you choose to replace the view ports.

Great data Ian, thank you much. As I recall the scratches were really light so we will see what we got once we have them out. I didn't think about them soaking up water,interesting. I used to know allot more about annealing when I was working on designs for small animal enclosures, but I'll have to dig that data out of my brain and filing cabinet and refresh. The two small view ports have a large bevel on them that would require turning them on a lathe if we need to make new ones. Having the old ones will make it easier to copy them. I have a lathe that should be able to do this for us. The basic circle can be water jet cut out of the sqare sheets here locally very quickly and for a good price.

Regards,

Brent
