Tool bit sharpeners
I am new to the forum and new to machining. I have several nice machines which I have yet to really start using. They include two lathes and two shapers. I am interested in learning how to sharpen tool bits and find that according to who I talk to there seems to be a number of ways to get the job done. Question I have at this point is what are the merits of having an actual tool bit cutter/grinder such as the model shown in Harbor Freight like: http://www.harborfreight.com/cpi/cta...emnumber=45707
versus the more traditional grinder:
The universal grinder is quite expensive and if you go for a non-chinese version the price easily soars. How do you cut exact angles including reliefs without one of the more expensive versions. They seem to have the tool holders that can be "dialed in" were as the simpler grinders will need some additional mechanical help to find and hold the bit properly not to mention the proper grinder wheel added. I was looking for a store bought tool bit holder that I could add to my surface grinder that I have which receives no use. Any comments?
