2nd homemade lathe tool
The other day I posted a thread about my first homemade lathe tool. Here's the second. I used the first to do the handle on the 2nd, which is a little bit nicer piece of cocobolo. Again, no finish, just cocobolo turned with the first tool and then burnished with the shavings. I didn't burnish or polish the ferrul so the copper looks pretty crappy. This one was glued up but didn't have to be split open like I did on the first one because after I turned it just drilled a round hole for the tang.
This one uses round bar stock instead of square bar stock because I want to try one of each, but the round bar stock (3/8") was a little skinny to take the screw so the machinist welded on a square piece to take the tip and this works really well.
This one has the sharp-cornered insert instead of the "radius corner" insert I showed on the other one. I bought 10 of each for $1.20 each from Global and counting the $20 I paid the machinist for his help, I figure the pair of them cost me about $40 and I just LOVE the way the first one works and have every expectation of loving this one as well. A full breakdown of the costs was given with the first one.
Based on a direct comparison by a fellow on a turning forum I'm on, the savings on the inserts (over the $13+ to $15 that you can pay for better ones) is really only about 2 to 1 since they don't last as long. He also states that they don't cut as well, but I've found that they give a very fine-surface cut when the tip edge is fresh and a better-than-roughing cut even when it starts to dull.
I haven't used the 2nd one yet so don't have a comparison for the feel of the square shank vs the round shank.
