Keith,
Here is a great discussion on homemade jigs:

I think Darrel Feldmate's approach is easy, costs peanuts, and is very
effective:

My post in the first link shows an effective modification. I have used
Darrel's system for two years now as a "temporary" solution. It has
become permanent.

hi to all,
i am still new to the art of woodturning and i am still investing in
high quality tools as i have always been told to buy the best i can
afford. i have been having probloms sharpening my tools as i dont want
to ruin a good tool with a bench grinder as i get the gitters when i
start to sharpen them.even at the best of times i think that they could
be sharper and neater looking. so i started to sharpen them on a good
oil stone this does the job but i dont know if they are as sharp as
they could be or good for the tool. any help on the subject would
apprecated. many thanks and safe turning!!
