Thank you for this. It is good to listen to these points even if they are already know to some. Having reminders of important things is great both for those who think they already know things and those who know that some things slip from memory over time.
I'm constantly looking foe something to do after "retirement" age, have the lathe and tools but haven't started yet. Your channel is a wealth of info mate. Much appreciated.
Good point. While that can happen you will also have other issues. It's always best to turn the whole bowl at one time. All the best to you and Happy Turning!
Thank you , thank you , thank you! I was unaware of many of the HAZARDS you covered! I am new to the lathe, and your explanation of WHAT NOT to do is great, but the explanation of WHY NOT to do it really helped me to understand the potential consequences ! OUTSTANDING INFORMATION!

It's always a good thing to go o over safe work practices periodically. Its not a secret that most of us can get complacent over time with doing things over and over. Its just human nature but by stepping back and refreshing we can remind ourselves and others too that working safely has huge rewards that are often taken for grantéd and over looked. Thanks Ken for reminding us of these key points!
Good advice! I grew up around my granddad's woodshop and I've heard him say "stand off to the side, I'm going turn on the tablesaw" a thousand times. It's never an issue until the day it is, and a bit of forethought can stop an emergency before it starts. Great channel, keep up the good work!
Kent, I often use a ‘Skewed Chisel’ to make the angle on the tenon rather than a spindle detail gouge. In addition I now have a diamond carbide tipped tool that I have experimented with.
Hi Kent, thanks for the great video. Safety working is the best way (PPE). Though a dust collection system and respirator when working a very dusty or punky or rare exotics. And having a vapor certified cartridge when using any propelled finishes. Have a great day
Excellent review! Its always good to be reminded. You explained the end grain tool rotation in the best way yet. I need to pick up a few more bowl tools for sure. I watched this at the perfect time because I was just getting ready to turn from a spindle rotation to the end grain rotation.
One of the things wood turning has taught me that I struggle with ( in everything) is patience and respect for the machine I'm using and physics. I used to tend to try and be aggressive in cuts. I don't now but it was a learning curve.
Kent, great video. It was just the reminder that I needed. Having to run my lathe from a seated position, it is difficult sometimes to stay out of the line of fire, but your reminders have convinced me to work a little harder at accomplishing that. Thanks for the insights.
I still find sharpening the tools to be the hardest part. I just got a variable speed grinder, and I’m hoping that will make it easier. My old one was a high speed grinder, and the steel kept turning blue; which is apparently ruining the temper.
Great video. I recently took a beginner wood turning course over a weekend. There were a couple safety things they didn’t bring up (face shields, eye glasses and body position) that you brought up in this video that I found excellent. I really appreciate you mentioning them as I’ve been doing them but started to question myself if I should be doing them. Especially the body position. Love you videos. Keep up the great work.
Kent one more item to never do is not wear your respirator. Fine dust and lungs do not get a long. Always wear your respirator. Great reminders I love your videos.
Hello good afternoon, excellent safety tips. Please, the courses are on a platform that allows subtitles with translation, specifically into Portuguese.
good basic safety video. Linseed oil or equivalent soaked rags balled up and discarded on floor etc are like IED's. At end of day years ago 3 of us were calling it a day. Left the rag on roughed in stairs, end of day ray sunshine on it. The smell of smoke, 15 or so seconds later, a ball of flames.
Kent, when you had your bowl to the faceshield incident, was the faceshield one of the Uvex you are showing here? There are many very basic versions out there. In my experience, the Uvex S8500 is pretty good for impact protection.
It was a full face shield as you see me wear, yes, the same one. The clear plex completely caved and impacted my face. The plex stayed in the frame, but flexed enough to punch me solid. If it had happened on my eye, it too would have impacted my eye and eye socket. I agree, I see people turn with "splash guard shields" and that is frightening. It's frightening mainly because they falsely believe they are protected. The non-frame face shields are nothing more than splash guards, in my opinion. All the best to you and Happy Turning!
Thanks Kent - always good advice! Glad your nose and teeth are intact from that accident. Trust me - I have that T-shirt. I would add to that list - Distractions! Keeping distractions to an absolute minimum. This includes music. I Absolutely Love my music - it gives me peace. But - I discovered music with vocals forces my mind to listen to the words. I know it sounds weird, but it's true. I changed my music to strictly instrumental music - music without big crescendos. Much Better.. And the TV in my wood shop is NEVER turned on when using any machinery. Yes, you can watch or listen to the game while your hand sanding and finishing, but Only Then. Always Enjoy your videos. 😊 Lowell
Lowell, Thank you for writing and sharing! Great point about distractions! I've had people come up behind me and make me turn around. Not good. I've kinda adopted an "I will stay focused on this turning" mentality. While I turn I try hard not to have my attention pulled away from the turning until the lathe is off and stopped. I agree about the music too. If you have a type of music that distracts you, turn it off. Happy Turning!
There are face shields and there are face shields. Skimp on one and you'll need safety glasses, or in my case, give up turning completely as I wear ordinary glasses too and the two do not fit under my shield.
On the second topic, you mentioned not to get aggressive with the gouge and let the tool do the work. As part of letting the tool do the the work, it would have been helpful to say RTB - Ride the Bevel. Riding the bevel allows the tool to work its best.
Another great video. I do have a question, I have many issues trying to finish the bottom of the bowls and not having great success. What techniques can I try to fix this issue?
Thank you Kent great video! What do you think about turning the speed past the vibration? I've seen some here on CZcams do this to get a better cut as they say. Take care and GOD BLESS 🙏🏻!
Stephen, rarely have I seen this work for a bowl blank. Spindle turners are a different story. Check out this video czcams.com/video/qkAwPg-fPN8/video.html Happy Turning!

I am starting to buy a few bowl tools starting today. I will remember from this post forward that I have told you I turn sitting in my wheelchair. With that I am still able to tuck the tool in tight and use my body to help with the swing. Bowls. I have nightmares over bowls. I know, WEIRD!
Thom, stick with it. Your nightmares will go away. Remember; persistent, patient practice will yield the bowls you imagine creating! All the best to you and Happy Turning!
Because I turn from my wheelchair there are times when I have to be in front of the piece, and (until I can get a dedicated lower stand) my head is not in the right position. I take as many safety checks as I can.
The face shield plex flexs and can allow an impact to reach your face and eyes. The energy of the impact will be reduced, but you can have eye contact.
@@TurnAWoodBowlsounds like an opportunity to make rigid or impact resistant face shields out of the material the glasses are made, so people don't have to double-bag for protection.

I disagree. Rules or not, I know from experience that the clear plex on the face shield can and will flex and impact your face when hit hard enough. And I WILL NOT take the risk of that happening on one of my eyes. Thank you, but will just have to agree to disagree.
Yeah, I used to ride on the tailgate of my dad's truck and drag my feet on asphalt as a kid too. LOL For a few miles, maybe, but something ugly will happen. Happy Turning!
Kent -- With regard to your discussion of using spindle tools on face work (such as bowls), you are correct that you should NOT use a spindle roughing gouge. You are incorrect to extend that prohibition to the other spindle tools you mentioned. A 3/8" spindle gouge is STRONGER than a 3/8" bowl gouge. (A bowl gouge has a deeper flute than a spindle gouge, so there's less steel to give the bowl gouge strength. A bowl gouge's deeper flute allows it to remove more wood in a single pass than a spindle gouge of the same diameter. The deep flute does NOT make the bowl gouge stronger.) Similarly, a detail gouge is stronger than a spindle gouge of the same diameter. So, there's no safety reason why anyone should avoid using a spindle gouge on a bowl. Indeed, Richard Raffan prefers using a spindle gouge. What about your diamond parting tool? Can it be used safely on a bowl? Yes, it can. You are correct to point out that it has a relatively thin shank, just like a spindle roughing gouge (SRG). Why, then, can a parting tool be used safely while a SRG cannot? Two reasons: First, the orientation of the shank is entirely different on the two tools. The parting tool's shank is oriented so it's thinnest part is facing 'up', which causes the rotational stress from the lathe to be absorbed by the thickest part of the shank -- where the shank is its strongest. In contrast, the SRG's shank has its widest part facing up. This causes the rotational forces to be absorbed where the shank is most easily bent. Second, the way the two tools engage the wood is different. A SRG is presented to the wood with a very wide cutting edge. A parting tool has a very narrow cutting edge. If there is a catch, a lot of the SRG's wide edge is apt to become involved. This can make such a catch very severe when, as you pointed out, the catch is in end grain. In contrast, a catch with a parting tool -- even if it's in the end grain -- is not apt to be nearly as severe. There's simply less of an edge to be buried into the wood. Don't believe me? Take a look at your bowl scrapers. They, too, have a flat tang that is wider than it is thick. Yet, bowl scrapers are considered safe to use on bowls.
Thank you for writing and sharing! I'm sorry but a spindle gouge, any spindle gouge is NOT stronger than a bowl gouge. See this video and the numerous explanations in the comments as to why czcams.com/video/jC95iQOtONQ/video.htmlsi=pcQO2EAKnu18l-YL No spindle tools should be used for removing the bulk of the material on q side grain mounted blank.

Welcome aboard Stephan!
All good reminders. I really appreciate your care and thoughtfulness.
I already learned every one of these tips. Unfortunately, I learned them the hard way. I wish this video had been available when I was just beginning.
You have the experience, much better lessons, although painful at times. All the best to you and Happy Turning!
Thank you. Every video has helped. I recently had a bowl come off the lathe because my speed was set too high. Lesson learned.
Glad to help, Michael. Yup, keep that speed down. Happy Turning!
If you’ve been away from the piece you have mounted, be sure to tighten it down when you come back. Wood shrinks. 😮
Good point. While that can happen you will also have other issues. It's always best to turn the whole bowl at one time. All the best to you and Happy Turning!
Excellent safety video, experienced turners should review it periodically to keep these important points fresh in their minds.
