I created the attached Excel spreadsheet (PM if you want alternative formats) about two months ago but never zipped it up for upload. Guests may have to register/log in to view the attached file.

It's basically a chart of pipe sizes and some calculations based on those sizes - for example, pressure (based on a specific force). There's also a chart for prices and McMaster-Carr ordering information, although that isn't too useful either.

Speaking of which, I'm surprised the McMaster-Carr pipe sizes chart hadn't been listed here yet.

I've noticed that pipe manufacturers have a lot of technical information about their pipes. Here's a page with a bunch of information from Charlotte pipe: http://www.charlottepipe.com/Default...type=ABSPVCDWV

Download the PDF and use it for reference from time to time. It contains most everything you need to know and then some.

Default CAD and pipe dimensions

When designing a water gun, it's often important to visualize how the water gun will look. Most of the time for me I'm only interested in spacial dimensions, so a 2D CAD program like QCad is plenty adequate. The URLs below will help you figure out dimensions of parts for CAD drawings

Typically McMaster-Carr gives dimensions and for many items they have technical drawings or CAD files already made.

Charlotte Pipe has dimensional information for all of their fittings. Their Plastics Technical Manual also has a bunch of dimensional information about their pipes.

Often weight figures are also given which can help you get an idea of how much your water gun will weigh.

Default Re: CAD and pipe dimensions

This thread seems to overlap with the PVC reference thread, which is also stickied.

I have a list of pipe dimensions for Schedule 40 and Schedule 80 PVC in the other thread. At some point I may go through and add thinwall PVC, CPVC, ABS, and perhaps even copper. Of course, at that point it would be difficult to find what you're comparing, although those materials are more common when experimenting with seals.

If you're modeling or otherwise designing the layout of a water gun, bear in mind the sizes of fittings. Sizes of fittings are probably more important than the sizes of dozens of different types of tubing, but with complex shapes (such as reducing tees, male-threaded to socket bushings, etc.), labelling could become too complicated. Maybe I could just take the length and width for the fittings for design purposes.
