No, not really. I have the spring loaded T handles (snap gauges) that you measure with a micrometer, but nothing for holes smaller than about 5/8". I do trust my reamers for size, but the chamfer on the end of the reamer is the reason I used the endmill instead. I've been machining for about 13 years now, and at least once a week I find something out that I commit to memory, saying "Huh!!! Won't do that again!!!"

So here we have the engine dressed out in all of it's pretty colors. I had to get my good wife to take the pictures with her cell phone. Right now it is taking better pictures than my $700 digital camera. I will post one more video of this engine running, and then, as Bugs Bunny would have said--"That's all folks!!!"

Question--do you have to have a special tool to insert helicoils? I have a couple of 10-24 threaded holes in my aluminum cylinder head that are getting kinda funky. I can buy a bag of helicoils for $12, but I I buy a "helicoil kit" the price shoots up to $45Brian Rupnow

"Have to"? I know of folks who say no. I have several helicoil kits of various sizes. They have a tap and an insertion tool in them, and that definitely makes it easier. I have not needed to do it without the tool.
Others say the taps are just standard ones, but the ones I have do not seem to measure to be standard.

What rickt said.
The insertion tool will just consist of a 10-24 screw with a protuberance on the end of it in order to catch and drive the tang at the bottom of the insert.
In addition to this and the STI tap the kit will also consist of a drill of the proper size to accommodate the STI tap.Home, down in the valley behind the Red Angus
