We've done some testing to see how much supported/unsupported 1/2", 3/4", and 1" EMT Conduit can hold before bending. The video with results can be found here.
Where am I?
In Maker Pipe Connect DIY Community you can ask and answer questions and share your experience with others!
Is there a way to connect 1/2-inch conduit flush? I see that threaded pipe inserts for example are only for 3/4-inch and ... but that is more expensive and heavier.
Are there similar connectors for 1 inch emt tubes? Sometimes, I feel the 3/4 emt is not stiff enough.
Has anyone used this system to build an indoor play structure for kids? I'm guessing the limiting factor is the load ... do you think this would be advisable?
What range of pipe sizes will the shrink wrap cover? Looks like most of the projects use 3/4" to 1" pipe. Will it shrink well on 1/2" conduit?
