RE: [TCML] Support brackets for a flat spiral primary - right tool for the job?
Thanks everyone for the helpful advice and comments. Lots of good ideas. It's what makes this list great :)
For a saw type tool, has anyone tried this? http://www.rockwelltools.com/us/Bladerunner_Micro.html I figure if it can do a lot of tasks with one tool, I am renting where I live - so less stuff (and not too heavy) to move later on would be better. But the last thing I need (as you saw in my video) is another cheapy power tool that only sort of works and leaves bits to cleanup on the part afterwards.
Thanks again
