Thanks Ed, I would recommend not waiting as long as I did. I should have done it right after getting my lathe when I first thought about it. Makes it so much nicer to use knowing I don't have those cheap plastic knobs any longer. The lathe took on a whole different "feel" to it over the weekend. Granted I am sure much of that is the placebo effect but still noticeable in my head if nothing else. Rotfl

Nothing wrong with the placebo effect if it works. Feel on these manual machines makes all the difference when using them. It makes you want to use them.

Nice job Mike, they look just the part.

Darren,
I hope your finger is healing well, I have to admire your fortitude (taking a few photos).

Clumsy bastard! After getting your hand fixed up maybe you should make an appointment with the eye doctor! That looks worse than it probably is or felt I bet. But still I bet it was quite a shock to see. Did you show it to your wife? Did she faint?

RE: Todays Project - What did you do today? - Roadracer_Al - 07-05-2016

Yeah, not sure I'd have had the presence of mind to whip out the cell phone and take pictures of that.

Several years ago, I had a shop accident which required a visit to the Emergency Room.  So I called my wife, and she sent me to voicemail.... three times in a row before picking up.   Slaphead

Just an hour or so to kill in the shop, so I modified 4 indexable insert cutters for a friend. The two on the right are 1" diameter cut width Walter F2330 high feed mills that come with a 3/4" shank. These are the coolest tools for a CNC machine because they take a maximum 0.039" (1mm) depth per pass but do it at feed rates of .024" to 0.047" (0.6 to 1.2mm) feed per tooth at the high speeds carbide can do. They're really nice too for helical milling a hole, anything from 1.4 to 2.0 inch, no pilot hole required. Since milling with these send upwards of 80% of the force straight back on the spindle bearings rather than side loading, turning the shanks to 5/8" from 3/4" is no issue.

The other two are 1" Walter F4038 long-edge helical shoulder mills. You can see from the one that's untouched that they are 1" Weldon shank and 1" cut diameter. I had told this friend that turning down the shank to 5/8" on a cutter that's 100% side loading is a bad idea. He said that he's only using them for 0.010" to 0.020" radial engagement on soft steel and would assume all responsibility. OK...it's his money, his choice. All these are being used in ER20 collets on rotary tool blocks of a live tool lathe. They don't have a lot of torque anyhow so the spindle would bog down before anything bad happened.

They all came out perfect, for change. ;)

The best part for me was that because my son had "borrowed" my shop vac over to his woodworking shop (my shop is at his home, not mine), he was charged with doing the clean-up. :)

P.S. - the finish on them is superb, just looks bad being smeared with LPS rust preventative goop.

Ed I completely agree. I have wanted to use the lathe more in the past few days and I am sure the new knobs have something to do with it.

Nice work.  The finish on the shanks looks great.

Thanks guys - the reason I took pics was that I can probably use them in my day job. In fact, when I called work, I was asked "did you take pictures". Once back, I'll get a copy of the x-rays as well. One can never have too much teaching material.

I've just got home after having my finger opened up, washed out and the tendons and neurovascular bundle inspected. The good news is that nothing was severed and the altered sensation is due to bruising to the nerve. That will take a while to heal but should make a full recovery.
