Does anyone know of a site that has general guidelines or a basic goblet that you can turn...looking for instructions on it from start to finish...thanks Dennis
Got it. Larry is a great all around turner as well. Take a poke around the rest of the site, some really great stuff there. A little early for the weekly inspirational link but... here is the direct link to the goblet section. Along with the above, you should be able to get where you wish.
I especially like those. Usually the stuff not mentioned is where I am having the trouble. I really like how all the woodturners (at least EVERY single one I have met) will share absolutely everything they know to you. It really is a passion of theirs that they are more than willing to share. I also have the passion, still working on the skill part, but the practicing is even fun.
MOST EXCELLENT sites!
I'm gonna be sure I get them promenently bookmarked at home.
Thanks both of you's! :)
Bill, What speeds are used in these operations? I've been guessing and wondered if I was high or low, relitivly speaking.
I start out at 500 and often jump to 1800 as the stock tells me it's ready. Things run pretty smooth so I've been wondering if I'm in the ballpark with the speeds.
Seems the faster I turn, the smoother things go. :)
Not an easy answer. Some turn faster than others, some more slowly. General guidelines are:
1) turn as fast as comfortable
2) bigger diameter, slower speed
3) spindles are usually turned at 2-3000 Rpm once rounded, pens maybe even a little higher
4) bowl initially at as fast a speed as possible without inducing vibration in lathe (keep turning up until vibrates than back off. Increase speed as the blank becomes more balanced
5) Best general rule I know of is that the diameter of the piece times the speed should be less than 9000 as a upper limit, slower is ok. e.g. a bowl that is 6 inches in diameter could spin at 1500 rpm, a 9 inch bowl, 1000 rpm, a 24 inch bowl 375 rpm etc. Most people spin their work slower than this.
The better you get and the more comfortable with the tools and your technique, the faster you can tend to turn. Usually better surface finishes are obtained at higher speeds (due to lines per minute) until vibration or chatter begins to lower the surface quality.
Looking for plans for a dining room table that can collapse down to 4 place settings and expand out to 14 to 16 place settings. To further add design problems, leaves, etc should be self storing.

Hey everyone,
I just wanted to let you guys know that on Wednesday May 22nd, at 2pm Mountain time there will be a special chat going on on Twitter about power tools. I know some of you are on...
We would always go for the older delta, they seem to be the best quality. Watch out for their new stuff, have heard mixed reviews. But 500 used is a bit steep, make an offer. One thing we all have...
