Day two of the knifemaking course
Showing the difference between a 4o Grit and a 150 Grit - both are made on a Zirkonium Belt 2000 x 50 speed 28 m/s
First knife with a hand rub satin finish 600 Grit lengthwise second knife 600 Grit Belt finish and third knife 600 Grit belt finish
Poor Andy drilling the holes. Done on a pillar drill with a 4,0 mm Drill Titanium coated with water cooling assisted ( D2 is just a pain in the ass - if you get it hot it already hardens)
Andy is doing some file work on the back of the blade. He use a chain saw file in a multiple angle vice. It is a quite handy tool to make it that way
Grinding and polishing job done on the belt grinder. Contact wheel serrated with 150 mm diameter and polishing is done by 11 m/s or 15 m /s
Shoing the ricasso whit the choil groove and the finished blade in the hand to give a idea of the proportions
Dear Ladies and dear gentlemen
Today is day two and we have started at 09:20 am and finished at 08:50pm . So e are both quite exhausted. And has learned today fine grinding at 150 Grit. Polishing at 220 Grit, 400 Grit , 500 Grit and 600 Grit. All stages of satin hand rub finish from 600, 800, 1000,1200,1500,2000 and 2500 Grit.
Laying out and measuring holes, drilling them on a pillar drill and countersink them.
He got a basic tution in file work on the spine and reworking the ricasso. We had been quite productive today and have accomplished a few things. As a teacher I would say he is doing pretty good and he is definately on the way. Tonight e had a discussion about the final knife design. So tomorrow there will be a big day for him. Hopefully in the evening we glue the whole thing together
I will kept you updated but please bear in mind after 12 hours in the workshop we are not really fresh and cheerful anymore.
After a long session under the show we were realising that are not black africans. I have to thank the guy who invented the soap. There as grinding dust all over the place.
The story will be continued
with best wishes and kind regards
John and Andy
