Faster than a Speeding Bowl
When you get labelled a “woodworker” by your circle of buddies, colleagues, acquaintances, and so forth you typically get requested (on the final minute) to create presents for birthdays, retirements, or colonoscopy appointments. So it was pure when a colleague of mine on the lumber yard retired that I discovered myself on the lathe pedaling away and making a Teak bowl.
I’m not a prolific bowl maker however I do take pleasure in face plate work now and again. This was truly my first alternative to do a bowl on my new Barnes No three lathe so I used to be anxious to see how she carried out. And since I’m all the time trying to attempt new methods I made a decision to do one thing totally different in the course of the turning. It ended up being a type of “studying experiences” which are often accompanied by colourful language and compelled timeout within the nook to consider what you might have accomplished. However in the long run this bowl illustrated the required talent for all woodworkers: the power to shake it off and repair a mistake with out chucking the entire undertaking and beginning over.
Let’s Begin From the Starting
I used my bowsaw to cut out a spherical-ish clean from a 12/four×9 hunk of Teak and mounted it on the lathe with a faceplate and screws to start truing it. The mass of the Barnes dealt with the additional vibration properly of an eccentrically turning giant clean. Furthermore I obtained no belt slippage in any respect as I used to be turning that outermost edge the place the leverage is excessive as is the speed. This was a concern going into the challenge and the Barnes didn’t let me down.
As soon as spherical I started to form outdoors of the bowl. I used to be capturing for a deeper fruit bowl form and that is the place I deviated from my typical strategy. As an alternative of making a tenon for the chuck to carry the bowl whereas hollowing, I turned a dovetailed recess. This manner I might broaden the chuck into the recess and the top end result can be hidden and tucked up contained in the “foot” of the bowl within the completed product. It made for a cool line to the bowl with a quick S curve tucked in on the backside. I even added a few ornamental particulars for enjoyable that additionally act as strains to write down an inscription upon later. I then went to work sanding and sprucing the surface earlier than flipping round to start the hollowing.
With the bowl flipped round I expanded the dovetail jaws of the chuck into the recess and received a good match on the angle and a safe maintain. My chuck jaws have been taller than the recess so I used to be a little involved that I couldn’t match the shoulder of the recess tight up towards the chuck like I often do. Nonetheless the maintain was strong so I went to work with the bowl gouge.
Minimize to about 30 seconds later
…and with a sickening crap the recess cracked off and the bowl went flying. Proper into my faceplate truly. Put on your security gear youngsters! Even this foot powered lathe can flip issues at over 1500 rpms.
“Good golly Miss Molly and sugar beets!”**
I stated loud sufficient for the mom strolling her baby throughout the road from my open storage, to show and shortly herd her baby the opposite path.
**this isn’t what I truly stated, however fairly an expletive typically heard from my spouse who spends her days educating fifth grade women
It’s all the time irritating when a screw up ruins work you have got already carried out, however when that work was carried out by furiously pedaling a lathe on a scorching and humid day, it stings simply a bit extra. And so after feeling sorry for myself, consuming a sandwich to replenish my misplaced energy, and getting a pep speak from my pet, Kenny, I used to be again on the lathe with the damaged bowl mounted as soon as once more to a face plate to evaluate the injury.
That is one factor about woodturning that’s liberating, it’s so straightforward to reshape one thing on a whim. And when the whim turns into necessity this flexibility can save a challenge. With a deadline looming I used to be hesitant to do this recess technique once more so I grabbed a parting software and shortly made a dovetailed tenon. Then I simply need to reshape the curve of the bowl to get rid of the flat and hopefully find yourself with a pleasing type once more. After a jiffy extra of pedaling I used to be proud of my considerably squatter but nonetheless fruit bowl like form.
With a little clear up on the surface, I used to be chucked up and able to begin hollowing as soon as once more. This time I lasted extra than 30 seconds and was capable of hole the bowl to completion with out incident. In the long run I used to be proud of the general form and I feel the bowl seems lighter and flatter occasion although it nonetheless have the unique depth I used to be going for. It humorous how a dramatic change nonetheless yields the identical practical area.
So What Did I Study?
No lesson will ever be discovered until some reflection of the incident is completed. At first I figured I had simply turned the recess wall too skinny an exerted an excessive amount of strain from the jaws of the chuck. It was by means of sharing my catastrophe footage on-line that I used to be given the top slappingly apparent recommendation that I ought to have matched my chuck jaws to the radius of the recess. Thanks Shawn In any case, I’m all the time seeing extremely skinny walled bowls popping out of the outlets of people that truly know what they’re doing.
Y’see through the use of jaws with a tighter curve I wasn’t urgent out equally on the partitions of the recess however quite concentrating the pressure in three or four small factors which was sure to fail. This reality was strengthened the subsequent day when I discovered a completely intact dovetailed wall that had been snapped off between two strain factors. I began to understand why lath chuck producers make so many various accent jaws. In fact I’m much more upset with myself as a result of because of the generosity of Straightforward Wooden Tools I occur to have a number of totally different jaws which might be silly straightforward to snap out and in in seconds with their Straightforward Chuck (excuse the impromptu business). Had I matched the radius I might have been capable of maintain my skinny walled recess and evenly distribute the pressure of the chuck across the bowl and never turned my bowl into a missile. Extra doubtless, I might have turned the radius of the recess to match the jaws that I’ve.
In hindsight its fairly apparent and I feel I’ve been fortunate up till now utilizing my tenon technique that I haven’t tousled the tenons with ugly pinch factors. I assume I’m even happier now that I’ve a chuck that makes switching the jaws out and in so fast…now I simply have to recollect to do it.
However with any undertaking, it’s the finish end result that issues. I just like the bowl and extra importantly the recipient of this retirement present was very completely satisfied.
