Juan if in doubt about bit angle- get a protractor and draw those angles. Fold up a few pieces of card stock (business card, etc.) to match these angles. Practice holding your Dremel w/ bit at these angles. Get a couple TB's to practice on, helps a lot!
I keep a small water container on the workbench for bit cooling. I run my Dremel 4000 around 15 on the speed dial + -. If you use too hi a speed aluminum will melt and clog the bit. A sharp knife or dental pick will get aluminum out of the flutes of a bit. Practice on a discard TB from whatever source look for sumthin' cheap/ free ideally. A mechanic shop/ tuner/ anyone who handles a volume of TB's could be a source. Ask if he has any TB's with damage/broken parts.
Take pics of the TB before/after Grooving and of anything you need input on.
Everyone likes Pics! good Luck and Good Grooving!

Well just did my first ever groove last night on my 1996 Ford Taurus. Probably needs to be regrooved. I think Ron told me a while back on way to tell if the groove is done properly. When everything is put back together and you start the engine it should show a SURGE of RPM's. My car did not do that.
I did reset the ECU but no conditioning drive. I had to leave for work. Although I did notice more POWER when I pushed on the gas. It wanted to go!
I hope I can regroove. But I accidentally threw away the aluminum shavings. I hope I can still regroove without the aluminum shavings. What's a highly recommended epoxy?
Here are the pictures of what the groove looks like and what I did with the PCV valve and the capped vacuum port.

Thank you all for the feedback. Yeah I haven't had the time recently for the PCV reroute to the breather hose. I plugged it before I learned about the reroute procedure. I hope Tracy or someone else can make this PCV reroute explained in a step by step process.
I talked to this a bit to my co-worker last night. He seemed skeptical and wasn't sure how this works. Some people are brainwashed and truly believe what the industry tells them.
