these are the pieces that have run through the jig. all have faults but im impressed with this set and think with fine tuning of everything i can flute a 5 inch cumberland to the tip. at the moment shape is still of no concern. im more interested in reading the flute after each one has been done . also what type of stone likes what. i.e. its still an experiment. , i'll worry about "pretty" later. the first piece of novaculite on left was the first piece to go through the kig. the jig wasnt stable and the piece rolled after i struck lever. running a flute down the left side about 3.5". at first i thought it was a failure untill i realised how far it traveled and through the fractures and steps it traveled. the second piece is george town . nipple and ridge where very good and only pressure was used on the first side. excellnt 3.25" flute. it broke in the jig when i applied to much force. think the nipple needed to be better. last piece of novaculite on right stayed together and will be left as is. flutes good on both sides . there are two fractures in it and i think if i tried to clean it up it will break. also fractured the tip while doing the second flute. this piece was done with pressure only.
the next two pieces are burlington. large and thick. 4.25" flutes. big one snapped when i struck lever. the thinner piece was all pressure and im going to clean it up some and drive a flute back from the tip . then if it stays together ill flute other side.
one thing i found yesterday is that the width of the flute is more affected by nipple size . a narrow nipple will drive a thinner flute if ridge development is good. still need to refine all techniques. i'll take pics of jig today and try to take a video this weekend of how im using it so jesse can offer some advice to refinement. gonna do some more chipping before i have to go plow away the snow. peace
