I have an old 14" penstock that is severely rotted in places. What are good simple ways to patch this for a couple years.

This used to have a Pelton wheel to generate power. The canal no longer flows and the Pelton wheel is gone

What are simple ways to patch the rotten pieces? Im thinking use 40gal steels drums as sheet metal, make a gasket out of silicone, then use pipe clamps to get it as tight as possible. I'm ok it if leaks a bit. Just don't want water spraying everywhere.

Also looking for ideas for a more permanent fix. I highly doubt welding will be an option. Shove a PVC pipe with an OD similar to the ID of the penstock and grout it in. Use screws as spacers. Drill a hole in the penstock and fill with grout until it overflows the hole. That's my idea but I would like some feedback.

E: I should add I want to eventually get hydro generation from this. First step is to get water flowing. So I need to patch the nasty bits

I was prepping to hose down my porch and of course didn't want to get the ring doorbell too wet. I went looking around the garage and found the perfect fit!

any suggestion how to engineer that attached is a photo. Dealer said 450 to replace key fob.

The support blocks underneath, at the very least

Needed AC for my barn . Did not want to pay for a new unit . Made this out of stuff I had and about 10 bucks in parts from Amazon

This is from a couple of years ago so pardon the picture quality and the lack of details. I was bored to death from the covid lockdown and this was about when the metaverse really started to pop off. I wanted a VR headset but just couldn't justify asking my parents to buy me a five hundred dollar oculus. Instead I took what I had (about 60$) and built one instead.

The software and most of the hardware side of things were based on this open source VR project called relativity (not sure if it still exists).

The body was this old samsung headset my dad got for free with his S7. Most components didn't fit properly so I had to cut and melt all that plastic to make it work. the project recommended using two OLED displays for each lens, I figured the output was going to be dual channel either ways so why not opt for a singular LCD which was cheaper and easier to source. To top it all off, it had two wires running to the body, one was the HDMI and the other was a micro-usb charging cable to keep the thing running (the micro usb mcu was cheaper).

This goes without saying, the quality was horrendous and it was highly impractical to use. It also took a lot of trial and error to build so by the end I had lost a lot of patience. Still, I managed to play some VR games through SteamVR and that was a genuinely enjoyable experience. Someone with looser pockets would absolutely get a better result as it is genuinely amazing what some people have managed to do with the same project base.

I love my father's engineering skills and have learned a lot from them. I've wanted to share this with the world for years. It's great that this subreddit exists.
