Had today free to finish up a turning project and finish making my hollowing tool handles. Started by cutting up (2) 3/4" boring bars and (2) 1" boring bars.
What I ended up with is (1 )-3/4" with a swivel type tip that i made days ago - (1 )-3/4" straight boring bar and (1 )-3/4" bar that holds a 45' type cutting tip.
Then I made (1)-1" straight boring bar and (1)-1" bar that will hold the same 45' angle cutting tip.
Total cost of cold rolled for the 4 bars was about $18.00 as long as I paid in cash...............figure that..............Total cost is somewhere under $100.00 and that includes the making of a new tool rest out of 1" stock - How does it cut now ? beautifully!!! The rig is made much more rugged than the others I have seen on the market but I chose the materials for that reason anyway to make one stout. The laser is dead on accurate but its a little bigger one than on my monster rig which I think is 3mw and the ones i used on this rig are 5mw - which is no big deal, the laser dot is a bit bigger but nice and bright. It is a bit more trouble to set the laser (2 securing points for vertical adjustment and 2 for horizontal) but consider the cutting ease ill live with it..........
I went out and bought different bolts - flat on top and made out of SS - much stronger and do not stick up like in the pictures - .40ea.......
Picture 1 - is the project covered in plastic bags and sprayed once a day while I had to work the last 4 days. Did not crack and I was glad because I wanted to try the boring bars on this pc. It is 12 1/2 wide and 15 1/2 deep.
Picture 2-3 are the vessel finish turned and hollowed
Picture 4- 1" bar with 45' tool tip in it - and I made another 3/4 to hold the same cutter
Picture 5 - 3/4 straight and swivel tip tool
Picture 6 - swivel tip cutter in 3/4" bar
Picture 7 - 3 older vessels with finish coats drying
Its not a hard project but is time consuming - I would say well worth the work.........................thanks
