What Did You Buy Today?

I wanted to try these kind of tool bits... so bought a cheap set to play with the HF lathe...

Looks like I just bought the same set.
Can I ask you to look at yours?

I have 2 problems, and one... well not sure. I would not think that the boring bar needs a negative rake.. but mine has it...
The 2 problems are the left and right screws are in the wrong spot causing the carbide to lift.
I am not sure if I want to keep them. I think I can fix the RH one, the left will require a lot more elbow work...

I played with the boring bar, and the RH tool since the RH was hitting the holder at the tip. Nice cutting, and I am breaking a chip on the same material that HSS, CNMG, and WNMG were giving me fits on. So that's a win. The other thing is it didn't break the bank, but now I wish I had spent more on the 16mm, rather than the 12. I could have reduced the bottom and gotten a beefier piece of carbide... oh well.

We'll see if the seller will replace the one holder.

I guess that means you’re in line for a piece of granite too?

Although I'd love to say yes, not really. (No place left in the shop!) I just thought a homemade diamond saw like that was really cool. There have been times when I would have liked to cut granite like that. Such as when I needed to cut granite edging, did it the old fashioned way, with a chisel. Came out good enough.

Quarries must use a version of that wire saw, but at an even larger scale.

I think this qualifies as a tool. 83" x 55"x13", about 7200 lbs of granite surface plate. It's actually the base from a former CMM.

I really need to sell this trailer to stop myself from picking up these large random finds ;)

WHOLLY GRANITE BATMAN... do you have a need for a plate that big?
Do you know what kind of stand you're going to have to build to support that monster....
WOW... WOWSER... :big grin:

Need? You mean I have to justify buying tools with a need? What happened to buy once cry once?

I figure 3/16 x 4 x 4 square tube to make 4 legs. 3/8 x 6 x 6 caps. 2” x 3” x 3/16 rectangular tube for cross bracing. Three point support probably not going to happen.

I was looking for a 3’ x 4’. This came along at a better price.

No you don't need a NEED... just curious if you were planning on working on big stuff, like engines, (That's even too big for an engine)... I guess I don't know what you would stick on a plate that size..
Maybe a mattress.:frog:

I'm GREEN with envy.. But I would have to build a new shop to find a place for that.

Mine are the 12 mm ... Here is the link to the set I got: 4 Piece 1/2" Mini Lathe Indexable Carbide Turning Tool Set.

I think you should return those and have them replaced for a new set... mine do not have that issue... Here, take a look:

And I agree, spoiled with how good they work over the other bits I was using... but I am just getting started, so I know very little... but these made working the parts so easy...

Thanks, it looks like your boring bar is also negative rake, that's what I was curious about.
I think one of your holders looks like it is not sitting flat. The straight in turning piece. I decided to try modifying it.
I first took a stone out, but then tried a needle file. They are not hardened and the needle file is working. I am moving ahead slowly. But I think I can move the pocket back a few thou and have it sit flat.
