any internal diameter from 15/64 inch to 6mm would do, and as long as its between 2 and 3 feet
No! Its not a good ideaI have did this before years ago and the microwave started to smokeYou can cook the potato in the microwave without the foil and it will be fineBut with the foil on and a high setting you could start a fire!
NO! if you want to do it the quick easy way in the microwave then wrap in some paper towel never put foil in the microwaveAlternatively you can cook in the oven wrapped in foil for about an hour at a moderate heat
Yes, it is safe to cook potatoes or other veggies in the microwave safelyThere is a trick to this, but it is very simpleIf you want to microwave potatoes, cut them in cubes as if you were going to cook them on the stove top2) put all in a microwave safe bowl (bowl size depends on how much you want to make)Once potatoes, broccoli or whatever veggie you are wanting to cook faster the safe way in the microwave with tin foil, after veggies are in bowl, rinse with water and drainRest of water will stick to veggies 3) Once you have the water drained, take a piece of tin foil (the back dull side of it) and shape it to fit the inside of the bowlNOTE: Be sure to have the tin foil's DULL (NOT shiny side) facing upward and fold any of the remainder of any foil downwards facing the bottom of the bowland under the shiny sideThen, once you have the dull side of the foil all situated with NO Shiny part of it showing, take some Cling Wrap and put over the top of the bowl using a rubber band to secure itFor a Medium size bowl, set the microwave to cook the cut and cubed potatoes to about 15-20 minutesBroccoli, about the same for timing, depending how crisp or tender you want itUsing Tin Foil IS SAFE when facing ONLY the DULL side up!!! It's worked for me for a LOT of years!!! I learned this easy tip a LOT of years ago and have been using it ever since if I don't want to go the long route.
If you want the outside to be crisp and the inside cooked, just put the gas or electric oven on very hotMicrowave the potatoes with no foil onGet them in the oven as soon as the microwave has finishedThis reduces the cooking time by a lot and gets a good result
McMaster Carr is my go to source for mechanical componentsUnfortunately they don't appear to have the particular inner diameter you're looking forI don't know your application, but if you need a very precise ID to mate with another component, it might be a good idea to buy 7/32 ID tubing and a 15/64 reamer such as McMaster 2995A119 and reaming the ID to size.
