    Advanced Grinding Rest

    Hi
    One thing I have never been able to do is off hand sharpening of lathe tools
    so up till now I have always used indexable insert tools and when they get blunt or broken
    just replace the insert but they just dont make fine cuts like a HSS tool
    I do have one tool that uses HSS bits and thats a Diamond tangiental tool which came with a little jig
    to make sharpening simple as it sets all the angles for you automatically
    Recently I found Harold Halls web page and have been trying some of his projects with a lot of success
    like his tool for sharpeneing the end face of end mills
    Today I finished building his advanced grinding rest which was a fun build with turning , milling and dovetail cutting.
    I still have to make the accesories for holding round / square tools ready to be sharpened but hopefully I can soon start using HSS tools that I sharpened myself

    Here is the grinding rest to Harold Halls design

    Woo that looks nice. Off hand is all well, and good. But nothing beats a proper tool rest. I have a sliding table tool rest I made for putting hollow grinds on plane, and chisel blades. The grind I can do with it is far superior to anything I can attempt to do by hand.

    Great job on that rest, DonRecardo. I need one and have been toying with a few ideas of my own. Nothing I've come up with is as good as that, though. If you don't mind, I'll take a few lessons from you?

    That movie is "Short Circuit". The sequel was a bit of a disappointment, but m whole family loved the first one.

    Thanks for sharing!

    This is one of the best jobs done I've seen anyone do before. Howard would be proud of you class of workmanship. Very very nice.
