This is the same vehicle I just reported. I'm doing it again because I'd forgot to mention the engine size as Ron has requested. Also, it was a 4 cylinder.

Ive got some connections from costa rica when you feel confident Ill set you up with some jobs. Dan gadgetman mo.

Thanks so much for the generous offer Dan. I look forward to taking you up on it. The challenge at the moment seems it will be getting comfortable cutting a 22.5-30° groove pretty much freehand, since I wasn't able to use the throttle plate to guide me much.

Apart from that, though I often find it difficult to locate vacuum leaks, I should pretty much be ready to go, as this was actually my 16th groove and my batting average is about 75%.

Any tips about mastering the new angle are extremely welcome.

Hi Jonathan,

It sounds like you are doing very well. As far as cutting the new angle...I touch the upper edge of the bit on the plate while holding it at the angle and cut down in maintaining the angle until it hits the bit shaft, then move to left to remove the 1/2 to 1 bit width remaining to cut. If you tilt the throttle body until the shaft is parallel to your work bench, it will not only be easier to cut due to the straight downward force but you can maintain the angle by keeping the shaft level. I hope this helps. Sometimes it is difficult translating physical movements to words.

Look forward to hearing from you more.

Hey Nick,

Thanks alot. Your description made it very easy to imagine what your talking about, and I appreciate the advice about tilting the TB so the bit goes straight down. I'm looking forward to trying that. The only part of the verbal to visual that throws me off is when you say you cut down until it hits the bit shaft, then move to the left (I'm with you to this point)to remove "the 1/2 to 1 bit width remaining to cut". I'm not sure what you mean by the part in quotes.

Sorry I don't have a TB in front of me, or I could probably answer this question myself, but when you hold the upper edge of the bit against the plate, is that only for the start of the cut, and as it goes deeper it moves away from the plate, or do you keep bracing the upper edge of the bit against the plate as you cut down?
