QCTP toolholders in aluminum?

[wrustle]

If you just want "occasional use" holders with no concern for quality, do as Ken stated and purchase the cheap off the shelf holders.   There's just no way you could make them for less than what you'd pay.  Plus despite the allure of being a "fun" project.....it could very well be a "pull all your hair out" type of project!!  

Though judging by the looks of your picture.....you have plenty to spare!!
