Thread: port n polish at home

hey guys thanks for the advice it is funny that you mention those books i bought both of them the last time i visited summit i am going to check it out

I did so for my porting project-works great and was needed. 10,000 rpm was too fast for most work, and Lord help ya if a cutter is out of balance at that speed.




Amen. I have an old Sears electric 1/4 die grinder and the damn thing scares me to death when I'm using it. It spins at like 20,000 rpms and has a slight vibration to it, so it shakes the heck out of your hands, but it really removes some material. But if the bit is slightly out of balance it will come flying out at you like a missle. I've dodged the thing quite a few times and had it hit me in the chest. I keep threatening to stop using it, but it does the trick if you only have the guts to hang on to it.

Harbor frieght has a air grinder that has a 3 inch extention{for getting in the port} and it is also variable speed and cheap!!!I also recommend getting a book on porting!!!!It also seems to me that ol Dave Vizzard goes into a little more theory behind what you are doing to go along with the details.Good luck!!! http://www.harborfreight.com/cpi/cta...emnumber=93621 like any "cheap tool" it will use more air than a quality tool,but you will not be full blast the whole time ,soo air consumption should be less than stated.
