Heli-grind versus Unijig 5
Greg Beal
Thanks to all those who replied to my initial query on the 2 June 2003
regarding the Heli-grind sharpening jig system. Very helpful.
Thanks also to those northern hemisphere turners who mentioned the
Wolverine. After a bit of research I do not think this is available in Oz.
A second question to those in Oz (or elsewhere) that may know. How does the
Heli-grind compare against the Unijig 5 ?
Both seem to do similar things but the Unijig has degree settings. It would
seem to me that this is an advantage over the Heli-grind for beginners
wanting to grind new chisels to the recommended angles but are not overly
confident in doing this without wrecking expensive new tools, whereas the
Heli-grind only repeats the already ground angle/rake of the chisel (skew,
gouges, scrapers, etc)?
Info on the Unijig 5 can be located at www.unijigproducts.com.au
Thanks for any assistance.

Hi Greg, the heli-grind does allow you to change the angle/rake of the
chisel.
I am pretty sure they even recomend you change the standard angle of
most new tools.
If you want more info on the heli-grind the manufacturer (John
Crawford 02 9546 2941) also sells a video which shows you how to setup
and use the heli-grind. The video is about $20 from memory, it might
help you make a descision, and really helps if you buy a heli-grind.

is Ken Port's offering of the True Grind system (look up Woodcut
tools). I think all three will work easily and quickly for
inexpeirienced or expierienced turners. To regrind a new gouge it is
easier to get an idea of the angle you want, rough grind to the near
profile and then finalize on the jig. Just a tip there.
