Okay gents this will be long but bear with me. ...
Some time ago I bought a parting blade (Somta Dual 20x4 blade) for a steal , the price was about $3. Around here it goes for about $ 70 new.
So I decided to make a rear tool post parting tool holder. I also must confess that until now I have only had dreadful luck with parting.
I wanted the blade to be as upright as possible and measured the top and bottom of the blade subtracted the two and divided by two to get the "angle" of the blade as shown here: (also the basic design )
Next I had to Square some stock material:
Then I had the Machinist vice (also one of my Earlier projects) to the correct "angle" I used my clock gauge for this purpose and a magnet to hold the blade here is some pictures of the setup:
The first pick is the setup before I changed the blade around ....
The measurement with the clock gauge
After that I located the edge of the stock:
I did not take pictures of the cutting process , got caught up in the moment and forgot about the pictures.
But I did use a dove tail cutter and wood ruff cutter to cut the slots for the bottom of the blade :
I made a dell to keep the top of the blade holder strait and are using the tool post clamp it self to clamp the blade.
Some pics of the holder in the tool post:
And YES it is cutting like a charm !!!
And the center line worked out well:
While I was at it I decided to try my hand at Chemical Etching ( The salt water method) and it came out quite nicely...
Just for fun here is my notes while I am working :
Hope you enjoyed it !!
Regards
Paul
