Some Wadkin info here. It may give the thread specs on the in and outboard sides.
Chuck inserts available for the Vicmarc 150 chuck: Chucks: Chuck Inserts
If you are going to make big bowls or platters, buy a bare chuck with the biggest set of jaws and be done. If you need smaller jaws later, that can be added.
I turn 95% bowls. This book has a lot about technique: Turning Bowls with Richard Raffan: Richard Raffan: 9781561585083: Amazon.com: Books
Somewhere I read an admonishment about big bowls, "how many people are going to buy a 24 to 30 inch salad bowl". My short bed Woodfast swings 20 inches.
People made bowls for many years before chucks. If you have a faceplate, start there. Screw the faceplate to what will be the inside of the bow,l rough turn the outside, making a spigot on what will be the bottom of the bowl the exact diameter of the faceplate, making it deep enough to put in screws without coming into the bottom of the finished bowl.
Remove bowl from faceplate and screw faceplate on bottom, centering on spigot on bottom of bowl. Rough out bowl, leaving wall thickness 10 to 15 % of diameter of bowl. Let dry and move around, it will shrink oval, how much depending on how dry the blank is, type of timber, section of the log, phase of the moon, or whether your breakfast toast landed jam side up or down.
I use the tail center all the time, when flattening the bottom I leave a nub under the center until the last, then move the tail stock back and turn that off.
The bowl may also crack, there are many ways promoted on how to prevent cracking, look up "drying roughed out bowls". Richard Raffan says, "no matter what you do, some crack & some don't. Depends on the above reasons.
This lady works big, see how she mounts bowl blanks: YouTube
Also: Big lathe question(s) | American Association of Woodturners
People here who work big, all use faceplates: Albert LeCoff — Wood, Revisited
Don't be shy about asking questions here, there are a bunch of bowl turners and a few who work big.So much timber, so little time.

[QUOTE=auscab;2147877]Hi Tony . The one Cat I mentioned is still around I think. As well as others Ive spotted and the foxes. I am still planning on getting the trap.
Not sure where the Cat problem fits into this topic, I must have missed it. However a trap is a sterling move. Saw a feral cat here one evening and borrowed a possum trap.
For the first SIX nights I set it I caught a cat each night!. Then nothing the next night, then another the next. Got 8 cats in 10 nights before no more were to be caught. We have the endangered "Stripey Barred Bandicoots here", that are extinct on the mainland. It was nice to help them out a bit.

Thanks Paul . I spent a few hours looking at all the links you posted . Great stuff !
I think I will start off with the face plate . I like the look of it and Ive got the gear for it . I'll get a chuck as well, Ill just back off a little and not rush it . Ive been doing a little looking at Pre chuck ways of bowl turning . A week ago I saw for the first time with Stuart Batty what a Jam chuck was .
I'm starting to understand the chucks better as well. The Vicmarc website was a good one . Makes sense, they have covered info on their chucks the best .
You put up a link that was a run of pictures in the Albert LeCoff link , and a replicating lathe is in there . 1822 . I follow those things , love them . That's a great picture of one ! I have one (much later) and its behind My first picture in this thread. Unplugged and covered in stuff waiting for a new spot in my new workshop . I had it running in the last workshop and used it . First one of those I saw was in a video of the Springfield Armory showing how Civil War gun stocks were made. I didn't know they went back to 1822. That's early . Suppose they could have been done a bit earlier as well.

Omitted Wadkin info from my earlier post: Wadkin RS, RU & RUH Lathes
From the above: "Unfortunately the spindle nose at left and right was altered over the years and, in addition, it is known that Wadkin would provide (within reason) any spindle thread the customer required, so allowing him to make use of existing faceplates and other fittings."
If you have a faceplate, take that to where you go to buy a chuck and adapter.
Turning bowls with scrapers: YouTube
One can turn bowls with a 5/8 inch bowl gouge and a heavy 1 1/2 inch wide X 3/8 inch thick round nose scraper.
Best not to use a spindle roughing gouge for bowls, see: YouTubeSo much timber, so little time.
