That's actually not a bad idea... kevlar turners jackets also with groin protection - Now there's an idea!

BTDT; in compression mode too, and before hollowing the bowl. But I've always stood aft of the headstock when starting high speed or odd-ball blank. Near the tailstock may be a good switch location for emergency shutoff; not so good for cranking up the speed.

stirlo, for the same reason you can buy a T-shirt with the legend, "It's only funny until someone gets hurt. Then it's hilarious."

Hmm...how do you finish your work? Jam/bowl chuck?

Wagon wheels - only done a couple that size!
Very rarely do any spindle work. Not into pens - do turn some larger stuff, but mostly in the 10" to 20" range.

Saw a nice formula somewhere but can't recall where exactly it was that I saw it:

Diameter x rpm's should equal between 6,000 to 9,000

i.e. 6inches diameter x 2,000rpm = 12,000. (This was in reference to bowl turning.)
I always turn at whatever speed feels comfortable, but have written that formula on my wall as a quick refernce just to check now and then.


For finishing the foot I have a homemade compressions chuck
Attachment 67838
and a set of 'cole' jaws that I use to reverse the bowl
Attachment 67839
or simply reverse it with tailsock support and finish off by hand.

Cracked wood is a dangerous thing... 'cept in my case, maybe a cracked turner is worse. I routinely turn bowls up to about 9 or 10 inches dia up to about 1200 - 1500 rpm for making the final smoothing cuts. At that, I'm always using the bowl steady. But if it's got any cracks in it, I slow it down a lot.
Glad you're still with us!

So instead of Funky Chicken we should now call you Ruffled Chicken some bruising on the stomach I suppose by now and those fingers at least you had the camera handy

Glad you ok FC and finaly we see that lathe

Lathe falling better secure it FC but then again it may be in line now and centres meet up.

Yep! that pretty much my modus operandi as well. Goes back to when I was a little tacker using my Dads lathe. Had a lump of Jarra fly past my head. It weighed around 2kg, took me a couple of weeks to get back into it and a change of clothes........


Still this probably is another twist on how speed can kill....

Been there , done that and that's why I love the foot sw. When I move away the lathe stops. Of course it also has it's problems but they are "livable" Sure hope there was no permanent damage to hands , body or confidence. 3000 all the time??? wow.

Brings back memories of a red gum bowl.
Threw on a gum line and hit me in the head.

Thank goodness for the triton respirator. It bounced off and hit the wall.

The vl300 did not move and the big red bar was useful.

You already got to see the lathe in this thread...remember...

Yeah I think I'll screw it to the bench now... And maybe bolt it to the house frame...

Hi Funkie

With a blank that size and speed its a wonder it didnt take off lathe and all after all it is a JET.

Think Safe and have fun Tony

What an experience! But you were lucky.
Did you want to fly over the lathe and take off that you tuned the speed up to 3.000 rpm's ?
I have done a file which gives you some indications on what would be the lathe speed in function of the diameter of a BALANCED piece of wood.
In you case the turning speed should have been around 2.000 rpm. But I guess, even at that speed, because of the crack, it might have blown up all the same.

If you want to test the very simple program you can enter the diameter in the left columns of the tables.

FC sometime back Skew posted a chart or suggestions for recommended speeds. I think I still have a copy somewhere or he may post it again if he reads this. If not pm him
