how does one seal the ends of the rubber hose to each other?
I ask because last time I started building a vac chamber, I left to get some pourable silicone to make the seal, and came back to find my buddy had tried to form the seal using 3/4" heater hose. there was a huge gap where the ends of the hose came together. no way it was ever going to seal…
He had also blown through the side of the vessel welding it to a shopping cart for some reason. ?!?
after (mostly) repairing the leaks, I re-purposed the device as a warm water bath for our CLS, a task it did well for several years. It then became the prototype for a warm cannola oil “parts washer” for precleaning all the sticky stuff off our glassware.
