bloodless injury?

Something weird happened today. I was making a mushroom from a bit of maple, sizing down the base of the cap. I was attempting to make a rather large cap relative to the stem, which required digging in deep with the parting tool. I learned a painful lesson about leverage when the tool caught and violently wrenched my hand into the work.

The wound is the damndest thing I've ever seen. My left pinky finger has a huge red spot from knuckle to nail. It felt like it should have been a split or a gash, but it looks like a gouge. It never bled a drop. It has a glazed appearance that makes me think I somehow injured and cauterized it simultaneously.

I can't quite figure out how I did that. It doesn't match the diameter of the workpiece, and it doesn't match the profile on the parting tool I was using. It looks like an impression of the tool rest to me, but the tool rest can't have gotten hot enough to cauterize this.

Mysterious...

Painful too. Remind me not to do that again!

OT ... I'm getting delivery failures to email I sent. Could you look into it?

You see. Nice thick gooey clotty blood. High cholesterol levels are good for something!

Take care.

No, I have no control over any of it at all, so I can't really look into it. I could point you at my real address instead of my SourceForge alias, but I've had more luck with people sending to the alias instead of directly to the actual address, strangely enough.

What kind of delivery failure? I've been suspecting for a bit now that I'm missing out on email from people. (Dave in Fairfax? Haven't heard from you since 1-02...) It's hard to know whether someone sent you an email if you don't ever receive it though, isn't it? :)

I did get one message from you today, with two questions in it. Have you sent more than one?

I think you are on to something, but I think the spinning mushroom cap may have had a cauterizing effect on the wound, not the tool or toolrest.

Arch would know about this. Could the cap have just lightly injured the skin so as to cause the leakage of clear or cloudy sera from the flesh, but striking no blood vessels?

How about...

perhaps at the speed it was turning, it burned his skin (which cauterizes at the same time) and left the "rut" from the edge of the mushroom cap?

probaby hurts like a son-of-a-gun.

No, that's it for now. I wanted to know the Pony Express was getting through before sending the rest. Lots more ideas & thoughts... Hopefully of value. ;-)

P.S. I'm not an insensitive bast*rd, sorry about your accident. I was feeling it before but realized I hadn't mentioned it.

How about impact injury simple? What you call a blood blister? Trap a finger between rest and cap, and whap.

Does most of the audience use parting tools under the cap? I'm a "pointy gouge" type. Allows a much cleaner cut.

Okey Dokey, I'll resend the messages. Can you talk to your ISP and find out what is going on? I don't expect, and I doubt that anyone else does, that you can fix the problem, but maybe if you whack the ISP up'side the head so they know that there is a problem.... Anyway, I'l send to the usual two accts, if there's another that I should try let me know. Almost got another box ready for you. %-) Dave in Fairfax

Try juggling an angle grinder. They often leave these self-cauterising wounds behind

I wonder if the first person who learned how to start a fire by twirling a stick did the same thing, before he or she figured out that another piece of wood was better than the fingers for holding the top end of the stick. Not trying to compare you with a caveman Silvan, just saying it's very easy to burn flesh on wood spinning at 1000 rpm, if a Boy Scout (or Girl Scout) can start a fire at something like 10-20 rpm!

I have a special parting tool for these kind of cuts, it's made from a portable planer blade with one side ground convex and the other side slightly concave--like a very shallow gouge with the cutting tip in the center at the thickest part. Definitely needs a strong, solid handle that won't split if you have a catch!

Seems best to me as well, especially the "detail" gouge format for longer reaches.

That's a happy image.

Now that you mention it, I took a knuckle most of the way off on a bench grinder, and it was anything but bloodless.

Any idea which of the two addresses is actually working? I only get one message when I do get one from you, but I don't know if maybe my mail server is smart enough to consolidate them or something.

I'm thinking about setting up an account somewhere else, as a backup. I'll let you know if/when I get it.

That it does indeed. It feels a lot worse than it looks.

What, for gouging out the "bowl" under the cap? I use the parting tool to cut down to the approximate diameter of the stem at either end. That's what I was doing when I got whacked. After I rough the stem down, I use a small skew to taper it up from the base, then I use the skew to cut up into the cap and form the top of the stem and the inside of the cap at the same time.

Seems to be working fine. Well, when I do it right anyway. Today was a much better day than the one when I whacked myself. :)
