No power drill of any type. I find it's too easy to lose control of the process. Look for a link I gave for a little hand held bit holder.
So, 2 months later I finally got around to giving this conversion a go.
LM, I don't what you are doing, or your patience level, but I worked with
the handheld for about 5 minutes and it didn't do anything. Maybe I wasn't
pushing hard enough, but I quickly lost patience and broke out the Dremel.
Set it on it's lowest speed and whizzed right through all 3 in under 20 seconds.
I think anyone with even a semi-steady hand should be able to do this with
no issues.
I will be using this process from here on. No need to try and hunt down LP
manifolds any longer. Cheap, quick, and easy.
Also, for those that are curious, I snapped a pic to give you an idea of exactly what
the difference is between a NG manifold that has had the orifice replaced to work with
LP and the other two still have the original NG orifices.
As you can see the top burners are a raging inferno, while the bottom is nice and blue
as it should be. I also did a test Sunday (no pics) by simply connecting an LP hose and
firing it up. It had the thermometer pegged in about 10 minutes on high. I backed all
3 burners down to low, and still maintained about 600 degrees, with the wildly fluctuating
yellow flames. I was good for a burn-off, but I certainly wouldn't have wanted to try and
cook on it. BEWARE the grills we see from time to time where the owner has simply swapped
hoses.
