My first time making some ribs and I wanted to know how long should I leave them in the oven and how high the temperature should beAlso, how often should I check up on them ?
Not knowing what your surface looks like I don't know if this would work, but I used to have to drill larger holes in electrical enclosures and if I had to center and drill a larger diameter I would first drill the diameter hole I needed with a hole saw in a chunk of dense wood at least an inch and a half thick, then clamp the wood tightly to the surface I needed to drill using spring-jaw welding clamps, with the wooden hole centered over the existing smaller holeThe wooden hole acted as a guide to keep the drill centered as I drilled the new perimeter around the existing hole If it's a part you can remove from the vehicle and take to a machine shop, they would be able to drill it for youI would have recommended a Klein Unibit but unfortunately they only go up to about 35mm (and buying one would probably be more costly than paying the machine shop.)
Problem with reaming it in place is you don't have a round hole anymore Can you make a plate with the size hole you want and bolt it in placeThen use this as a guide and use the hole saw? I have done something similar to an old truck with a broken bolt i needed to drill outIt worked great for me Or find a way to make that carbide burr stay steadyRig up something
I would use a round punch testicular discombobulator
If they are thick/country ribs (pork) I boil mine first.(about 30-minutes) Then-I bake at 350-375 [F] about 15-minutesThen I begin to add thick layers of BBQ sauce.use a rack in a baking sheet//that you sprayed with cooking sprayYou may want to line your baking sheet with aluminum foil.for easy cleaning.
