Great review, Sam. Since Ron Brown's products don't seem to be carried by many of the online woodturning sites, I doubt I would ever have known about this item.

What I noted as missing is a means of centering and securing the rim of a tall vessel where it seats against the baseplate. That is, if a hollow form, for example, only has a rim 3 inches in diameter, that's not much of an area for it to seat against and it could get all wobbly and create a bit of excitement.

Nice video Sam. Thanks for your time...

A great review Sam, and that looks to be a very versatile and useful piece of kit. Cheers Mike

Sam, I'm sure you have heard of one of our most famous woodturners in Hawaii, Jack Straka. He showed us how to do this over 30 years ago. Looks like the exact copy of Jacks idea.. What we do is leave the piece in the faceplate, put the faceplate in the tailstock, and you have it perfectly centered in the Straka chuck, as it is called here... Going to watch the rest video now, hopefully they give Jack credit for his invention... Aloha from Maui

Being a new turner, and having done a fair bit of research before I purchased my lathe, I found Ron's site. I agree it is chock full of good information.

great demo Sam

Nice thorough review; thanks for sharing. I've always pondered making one, but it may be much easier to buy one with all the goodies and save some time. Cheers!

tip: you can use the swing feature of the head-stock to cure the problem with the handle, just swing to 90 deg. (ie. the chuck facing you), this also works for bigger bowls too. OR if the head-stock can slide along the bed, move it to the far end and use the aux. bed extension under the lathe bed ( on the leg set)- this is where the banjo goes; and turn from the tail end, like how an outboard motor runs in a boat, only the propeller is the bowl you are turning!!

Thanks, Sam ... I have been eyeing one of these since Ron introduced them. You have answered every question I had! I have no doubt I could make a donut chuck, but I do doubt I could produce the same quality product, and besides, I would rather be turning!

Thanks for the video with useful information.

Nice review. Not sure if I need this chuck since I have a vacuum chuck. Maybe later depending on what direction my turning takes. Either way, thanks for taking the time to review this product!

Detailed review Sam. I do have one of Ron Browns Longworth chuck but I think I'll still with my vacuum chuck!

Sam, Ordered mine 1st day Ron announced it was available. I use it for spheres, spoons, ladles, scoops, and of course, bowls and vessels. Does exactly what Ron says it will. And it does run true. I got the 12 inch model but use it on my 20 inch swing 1985 General 260 as well as my Delta 12 inch midi. Another happy and satisfied user. Hey Ron, when do I get my free one?

Great video!!!

Thanks for the review, Sam. I have looked at this for some time now and based upon your review, I believe I will pull the trigger. I also note he has an offset rig that is along the sam lines as the doughnut chuck. A bit pricey but interesting nonetheless.

I had previously gotten a longworth chuck from Ron Brown, because for the price for it was very reasonable and I knew it would be more accurate than what I would be able to make. I didn't know he had a donut chuck, so I checked it out and ordered it.

Fantastic review 👍🥴👍

Great review, Sam! Building something like this has been on my radar for a while, but after checking out the price of them on Ron's website you pretty much cant afford not to buy one!

Genial system. Nice work. Thx for this video. 🤗😊

It looks to me that it would probably be better to do the final tightening with a wrench, turning the knobs might over-tighten it when trying to align the "T" handles. As you said, it is going to take some time to get the assembly procedure down just right. It looks like a very well engineered tool and may be worth the money.

Sorry, was mir an diesem "Donut Chuck" nicht gefällt ist dass die Maschinenköpfe der Schrauben so weit heraus stehen. Ich denke dass hier ein sicheres Arbeiten mit Schlossschrauben möglich wäre. Ansonsten eine feine Idee.

A vacuum chuck is nice, but can be expensive. And, yes, I do have a vacuum system and use it almost daily. But, for ladles and spoons with offset handles like Soren Berger makes, I prefer the doughnut chuck to a vacuum.

Great review. I made one some years ago out of plywood, but recently replaced it with a vacuum chuck. It seems to fit my bill, what am I missing?

Very informative video. Recommend everyone to get on Ron Brown's list from his web site. He is a true craftsman and person. Has many great products and free stuff too.

being someone of very limited financial and extremely limited equipment,,,,the gizmo looks awesome,,,,,,but,,,,,,there are just way too many parts,,,,it would appear that it was designed for those that think that they are all great woodturners,,,,,,there are those of us who want to turn but we just don't have the means to be all fancy and technical,,,we deal with what we have or have not,,,,we make accessories and equipment,,,,,,,,,heck my son in law made me a wooden wood lathe...we are still working on the gremlins but it is a step forward and for me it is like having a goldmine,,,,,,,,

nice

Wish you hadn't shut off the camera while you were trying to true up the rings. As a newer turner, it's something I struggle with and it would've been nice to see your process and how long it actually took in real time with someone of your experience level. Maybe a separate video?

That is one of my dream tool, the 12 inch 1x8 tpi would fit my midi lathe just perfect. I built a doughnut chuck when I needed to hollow out an already turned sphere (for my 2015 Christmas ornament) with very simple materials (2 pieces of plywood, and 4 long wood screws) which worked perfectly, but it was made to fit the specific sphere I worked on. A set like this would be just a perfect addition to my poorly equipped shop, and it will go right on my Christmas gift list (right under a band saw) which no one will see. Looking at how this kit is made makes me feel like I could fabricate something similar of my own, to a degree, since as much as I want, I won't be able to afford it any time soon, but I love the challenge of calculating materials and costs to see if it's even economic for me to fabricate (in the end most of my fabricating ideas end up costing on paper much more than actually buying the commercial product, so I don't bother and do without). Thank you for sharing this tool review Sam, always a pleasure watching you work and explain things we all take for (almost) granted. Yuval.

Seems like a good tool but don't really understand why you put in all that effort in to make the front ring run true? The lip of a bowl would be running true against the back of the chuck & you centered it with your dimple in the back of the bowl. The bowl would still spin true, even if the front wobbles due to uneven tightening of the bolts. I got a digital display & RPM sensor on ebay for less than a tenner to fit my union graduate. If there's enough room in the headstock of your oneway it should be easy to fit

Some people doesn't have money like you do.

Rob Brown comes across as a used car salesman, and his" inventions" are just clone of things other people actually made.
