For those who haven't yet internalised these shapes your method gives them an excellent start with making some visually satisfying pieces.

Thanks for sharing.

PS - these shapes...

I do have a few pieces where I've made an abrupt change from the catenary shape in the bottom of the piece into a closing form on the top of the piece, in which case the bottom catenary is more...

.
I have what I think are some examples, but it's a fine distinction between some true parabolic and some catenary curves...

And, of course, the catenary comes in many variations,...

See Doug Thompson's video on using the Vari-Grind jig starting at... https://www.youtube.com/watch?v=ttYyulsM7wg&t=541


Like Doug, I also use 1-3/4" protrusion out of the Vari-Grind and Tru-Grind...

My passion is for woodturning, not selling things.

I have only ever marketed my woodturning twice. Both times to prospective galleries. I took examples of my work and a more extensive photo...

Nothing scientific with what I did, Richard.

Yes, all the of the variables you identify would change the results, but at least I have something more than my nose to go by. Without the particle...

I'm not sure how many board feet you would hand plane in say a minute, Richard.

If I'm turning a 12" bowl at 2,00 rpm then at the circumference that's a length in inches of Pi x R = 18.9" and at...

Yes, Dave, PM 2.5. That micron size is the one of most concern according to the respiratory experts. The PM 10 is what you would see yourself under the right lighting and what would colour your snot,...

Reading after shearing cuts with D-way HSS gouge...

Certainly much less fine dust, but no dust?

I'll do some measurements the next time in my workshop to get some precise numbers.

Workable cheaper solutions (which 3M and the like are not) are the holy grail of PPE for us woodturners.

Thank you for sharing your solution, James.

Both Nova and Vicmarc chucks use two locating rings for the jaws.

I have half a dozen of each and both are very good chucks. Vicmarc came after Nova and they could have gone...

There is a scene in the Crocodile Dundee movie where Mick Dundee is approached by a street hoodlum in New York wielding a stiletto. His partner calls out to Mick, "look out he has a knife!" to which...

Note: that is for hollowing in end grain!

I don't recommend that inside pull and/or scraping cut with a bowl gouge used on the inside of cross grain pieces, unless you want to live dangerously. To...

Most speciality hollowing tool setups are designed to solve the problems associated with small opening, undercut rims and long reaches off the tool rest encountered when making hollow forms. If you...

Any size skew will do for turning straight thin spindles... the 3mm spindle on the left was done with the 1-1/4" skew next to it...

When I get the setting I want I then make my own templates so that I can quickly setup again to get that grind if the settings have been changed.

Nothing grand, just a bit of ply or block of wood...

Here is what I'm referring to there...

You can use it in both shallow and deeper bowls



When you press it into a bowl or...

Yes, coarse abrasives is one of many methods for removing any hump, but it will also leave deep scratches in the side grain in the bottom of the bowl, which then requires a lot of further sanding...

===> Ditto!

An interesting and entertaining video from Ronald with his coring machine that works the opposite way to Oneway, Woodcut and McNaughton by both holding and cutting the blank from the face side. That...

If I had a dedicated coring lathe always setup and ready to go I might experiment with taking the first cut to part off the outer rough cut part of the blank or even do that with half billets (log...

I stopped cutting blanks into rounds myself a very long time ago. Too hard on the smaller bandsaw blades and especially with deeper cuts and on the tougher woods we have down our way. If I didn't cut...

Good point Roger. With the small hubs on the CBN wheels i have done away with the flanges that come with the grinder and that can leave you short on thread length on the shaft. If using pressed...

Also to the front of the bench with the slide(s) hanging out free from the bench so any tools that still have handles attached can swing freely around when grinding the wings.

Some like to be able...
