Does any one know where I can get a solid block of PCV that is 4"X4"X6"? I came up with an idea for a breach loading cannon that would use a block of pvc to from the breach.
The idea is to have two 4"x4"x6" blocks of pvc that are hinged at the bottom and that have a latch on the top. The barrel would be in two pieces. One piece of barrel in a hole drilled in each block of pvc. The mating suraces would be gasketed to from a tight seal. I would likley have to have the block sent to a machine shop to have the hole put though it that is the same size as the outer diamiter as the pipe.

Check McMaster... Don't expect it to be cheap though.

yeah that much pvc is gonna be very expensive

You might be able to find something like 3/4" x 4" x 10' stock at the local hardware store since it is sometime used for exterior moldings. Gluing up thinner stock might also be cheaper.

Yeah you might try cutting up a big piece of pipe, flattening the sections, and stacking them into a big block using glue or epoxy. But then I wouldn't really recommend using that as the basis for a pressure vessel.

little bit more reasonable and I can make it work.

Save it on you documents then use the spudfiles picture uploader or an image hosting sight.

I tried but it said that it wouldnt accept the format

Use a picture hosting website like www.photobucket.com then use the provided direct link in between the "IMG" tag.

Well although i realize that you are trying to be revolutionary, dont expect it to be cheap. I do look forward to seeing this though. But could you use metal instead?

Spudfiles works fine with the .jpg format. The file size must be under 350K in size. I edit my photos to 800X600 or 600X480. These sizes often work fine. BMP photos are not accepted. Save it as a JPG or GIF. If you read the info when adding a reply or editing you post the link under Add an Attachment that says Allowed Extensions and Sizes pretty much lists what can be uploaded.

For photos the link shows;

Here it is. Red represents gaskets.

A cam lock set up would be sooooo much cheeper and easier.

I never have been much for simple and even if it does cost a lot of money it will be unique
