- Here you see how I create two of my signature Wavy Bowls. These were turned from casuarina that was growing six weeks earlier, then microwaved. You see the turning portions of making these 130mm (5-in) diameter bowls in real time.
I learn so much from your videos, nu fuss, nonsense or fancy expensive accessories. Thank you
I really appreciate you sharing your ideas, how you create them and explaining all your steps along the way. Thank you!
I appreciate the great ideals you have given me to try
Great work, and a great idea!!!
Oh... I've got to try these!
I'm very grateful to you showing the quick microwave dried bowls. They really make for a quick and fun project and are great practice.
A great piece of wood sometimes justifies a split. Would you consider a video on how you deal with a split
Great to watch and learn - many thanks, love these bowls - I shall try some!
Thanks Richard very nice turn
Love the grain. it's always interesting watching your videos.
Very beautiful grain in those bowls Richard.
Always great to see how you work a project. Interesting crystal formation, maybe it is the tree's sugars drying out and crystalizing.
Excellent as always, thanks
Beautiful bowl
Very attractive wavy bowls-almost flower like. Greetings from Tasmania Australia 👍😁🇦🇺🦘
I like the repetition of your turning multiple pieces, Richard, as it highlights and reinforces the important points and also explains the many small nuances that are different. I am always learning something new or relearning somthing I have forgotten.
I used to do a demo at the annual Utah Symposium turning 8x3-in bowls for 90 minutes without saying much, so people could see the rhythm and repetition. I'd do profiles for an hour, then hollow them. Usually completed six, occasionally seven.
Beautiful... wood moves, you know it will and you will not stop it. The trick is to use it to your advantage
A pleasure to watch this masterclass in woodturning. Many thanks.
I love it!
Thanks Richard.🙂🙂
Just perfect
Every single time I watch yiur videos I learn so much. I have so much admiration for your skills. Can I ask if that thread chaser is a wood turning specialty tool or something you have adapted. Once again thanks so much for helping to improve our skills.
The thread chaser is one half of a pair for chasing thread on wood. I've made larger versions, one of which you see about 10 minutes in in th-cam.com/video/biBY2eQTJ94/w-d-xo.html
just bought my 1st vicmarc VM100 chuck and some shark jaws. I hope you're proud of me Richard!
A very sensible decision you'll never regret.
@@RichardRaffanwoodturning I'm looking forward to it. very well priced too.
Interesting ... Thanks!
The wood is very nice, alot of character..
Hi Richard
Is the microwave on full power or defrost? Looking forward to trying this on green olive that I just acquired. Love your work and delivery btw, best on YT
Full power every time.
Bravo, they are beautiful... 👍😀How many minutes did you leave the bowl in the microwave?
There's no hard and fast rule for microwaving bowls as there are so many variables concerning the amount of wood and its moisture content. I talk about these particular bowls towards the end of the video. I usually start small bowls on about 60-90 seconds, whilst larger bowls in other videos are cooked several times for at least 3 minutes. You need to keep a very close eye on any bowls being microwaved so you can switch the microwave oven off the moment you smell hot wood or hear it sizzling.
Those are some lovely shapes and excellent on the use of that other sparse commodity besides wood, time. Are these more ornamental than funtional? I don't think I'd dare to eat breakfast from one... Does the wood retain those different hues? Or is that a feature of this particular tree? Would the blunted tailcentre work for heavier pieces? Or would you suggest a jam chuck or regular chuck? Many thanks for another excellent video.
I see these bowls as both decorative and functional. They can handle your milk and cornflakes, but there are more suitably shaped bowls for that purpose. Wood never retains its colour but the heartwood should remain a lot darker than the sapwood. I used the blunted tailcentre to show one way of supporting the work, but I usually use an MDF disk as you see in many other of my bowl videos rather than change tailcentres.
Thank you for a very good video. It didn't seem like you chanded the speed of your lathe at all ? You only sanded down to 240 grit ? Thanks again
I find 240 grit usually more than suffecient althoug I occasionally go to 320. The preoccupation with finer finished is comparatively recent. In the early 1980s few turners sanded beyond 180 grit but that was before turning took off as a popular hobby it is today.
Great video again, what power do you have the microwave on richard?
Always full power on every microwave I've ever used.
I have a question. While watching you adapt to a flat piece on the tail stock for the second bowl it occurred to me - would it be possible to rather loosely fit a bowl into a jamb chuck with a flat piece on the tail stock in order to insure the piece is running true? (While it is turning at a very low rpm) I seem to always have an issue trying to get the foot of a piece to run true while doing the finishing last cuts on the foot. ( not entirely sure if this is because the wood has already started to move or if its slightly out of whack?) It seems to me that it might be possible to have both ends of the bowl loosely jambed (with a certain amount of firmness) - just curious if you recall having ever tried this?
Ideally I leave enough thickness to accommodate the tailcentre as in th-cam.com/video/oJ9EQ9LfDWg/w-d-xo.html, or I use the small round of MDF you see in the rounded bowl videos. I used this flattened tailcentre just to show another way of doing things.
Hello Richard, can you tell me where you can buy the thread cutting chisel?
Any of the specialist woodturning suppliers should carry thread chasers, or you can make your own grooving tool as I did for the sets of beads in th-cam.com/video/biBY2eQTJ94/w-d-xo.html
What do you add to your epoxy to make it black
I have a large jar of African blackwood powder accumulated decades ago whilst turning endgrain boxes. Coffee is a widely used alternative, or powder paint. Any fine powder is likely suitable.
Do you have a vacuum chuck?
Not now, but have in the past base on a vacuum cleaner. You see drawings of the setup in my books Turning Wood and The Complete Illustrated Guide to Turning. www.richardraffan.com.au/books-and-dvds/ . For many years I was turning jarrah burl that was full of fissures: a vacuum chuck wasn't much use.
Richard, perhaps this is an opportunity to bust another myth?? Does the wall and foot need to be a very consistent thickness throughout to avoid cracking while drying in the microwave? You said the wall thickness is about 1/8 inch or less, but no mention of how thick it is at the foot. Thanks.
Having an even wall thickness and even density of timber certainly makes splitting less likely, but I usually get away with a heavy foot which tends to go oval rather than split. Uneven density is more of an issue: if there's a knot in otherwise bland and even grain, spliting near or across the knot is very likely.

My understanding is the crystal is sapwood residue seeping out from were the heartier timber meets the sapwood. Seeing the crystal like substance form is a good indicator of the timber structure about to fail. Generally due to heating to quickly or heating to much. In some circumstances it telling you to stop heating altogether otherwise it could explode - ask me how I know! (depending on wood type). Crystal to the level you found are likely to ge stopped in time before this take place. However if you see this crystal like substance develop take caution.
Not sure of the correct terminology of the crystal so stuck to your reference.
I've had crystals oozing out of many timbers but never had any ring shakes resulting from the annular growth rings splitting as a result of microwaving. Splits are always radial. I've never had wood explode from microwaving. I want the moisture within the wood near boiling so it's forced out of the endgrain, thereby causing more shrinkage in the outer layers of the wood. It's this that pullys down the two quartersawn surfaces to create the saddle shape in an outflowing bowl.
