It was going to be a small salad bowl. Now it’s a nut bowl.
My lathe (I got if for free), does not turn quite true and the tailstock does not line up properly with the headstock. This leads to challenges and vibrations. The walls on this ash was about 3/8ths thick when it could not handle the work I was doing from the inside and cracked. I sure wish I had a proper lathe. . .

I finished it with Watco’s chopping block finish. It will make a nice nut bowl.

The bowl looks great, don’t let the crack get you down.

The only pain is that the project started with 2 ash bowl blanks that I bought at full retail price ($6 each). I no longer shop there, I found a much better wood supplier since then.

Good job. Should be a way to realign your lathe. Contact manufacturer.

So what’s a litle crack?

Hey, there’s statues in the Louvre that are missing the ARMS!

So again I ask, What’s a little crack? :-)

Nice bowls.

I have in times past took a cracked bowl to my band saw and saw it on the crack. Then tape back together and continue sawing down the crack till I got both sides straight. I then glued it back together. Makes a great conversation piece when folks look at an oval bowl and ask how I turned it like that.

What brand of lathe do you have?

Thanks for the encouragement guys.
My lathe is one of those older Craftsman (though some others made the same style) that have a pipe for the bed. Like this : http://i1184.photobucket.com/albums/z339/jakeenns/2013-01-22114211.jpg
There is no way to realign it. There is a tongue that runs the length of the bar at the bottom, held on by rivits. These are notorious for coming loose leading to a terrible vibration. I took the rivets out and tapped the holes and put in proper machine screws and that solved much of the vibration and helped a little of the alignmentm but there is not much more to be done except make small slow gentle cuts all the time. It took me about 2 hours of turning to get this little simple bowl turned.
Still, I have a lot of fun! And that is the main point, right guys?!

The reason I asked what lathe you had is I suspected you had the Craftsman. I had the same lathe and I also had alignment problems. I took it apart and replaced the rivets in the first 1/3 of the tube which is where they were loose. I aligned it before I tightened the rivets after I installed two centers in tailstock and headstock. That trued it up right on the money. That style of alignment method is not the best in the world. I wonder if you noticed the adj screw under the base of the tailstock. If so nuff said. If not you might try adj it. I think it is for tightness of the tailstock and may make not be intended for alignment I forget.

I don’t know how you did the tightning of the tongue and you might have did it this way but if you loosened all the screws a little and pull it into alignment then retighten them do you think it would hold. Just wondering.

These steps werked for me but they may not help you. I was just relaying what werked for me.

Thanks for the info. Yes, I noticed all the screws on the tailstock. I was actually thinking about getting someone to weld the thing instead of relying on the screws.

I agree with joein10asee. The original design looked so nice.

You could have inserted a contrasting wood and continued it through to the bottom blank along its grain to make it look like it’s on purpose. But with the shaking lathe, it probably would have meant having lots of pieces exploding throughout the shop . . . and no bowl at all.

Thanks for sharing

I actually thought of welding too but opted out when the new rivets werked. One prob with welding is you would have to assy first or wouldn’t be able to get head and tail stock on. What I ultimately came to the conclusion was that catches would put pressure on the tool rest which has a mechanical advantage because it sits off center with the tube which would loosen rivets. I used to get lots of catches in the past mainly in retrospect of having dull tools. You say it is somewhat better aligned so hope it werks better also.

Have fun the best you can and save your money for a better lathe. Haaa Haaa

On mine the bed pipe comes right apart just fine. I took off the mounting bracket at the far tail end and the pipe, then the tailstock itself slides totally off, and then the pipe just works it way out of the head stock (with a little muscle – no tools) So doing some plug welds in the holes and then grinding off any excess that extends too far should do it.
But, yes, I will have as much fun as I can while I save my $ for a better IE “real” lathe. :)

Doe, thanks, that is a great idea. I will need to remember it for next time, when the walls of my piece are thicker than 1/4 inch.
