Oneway problems

Keith Tompkins

>I've been teaching at a school with 7 Oneway 2436 lathes. A couple of things I've noticed about these machines; I'm interested if others have noticed the same problems.

1. Speed control: the speed control knob on the articulating arm is just below the on-off swithes. It is easy to accidentally brush against the knob, which rotates extremely easily; hitting the "on" button after doing this may give you a big surprise. I recommend that students use the magnetic on-off switch instead, avoiding the problem.

The instructor machine is a 3 HP 2436. This machine, no matter where the speed control is set, has started several times at full RPM. I was warned about this from other instructors, it happened to me twice. Anyone else have this problem?

Also, the handle for adjusting the tool rest is right on the front of the banjo. This make shear scraping (Ellsworth style) with the handle held very low difficult, as it is right in the way.(My General has threaded bosses on either side)

Otherwise, these machines have worked out extremely well.Your comments are appreciated.

==================================

Sounds like a tech support call to Oneway is in order. That is VERY dangerous and I'm sure Oneway will want to hear about it.

>The handle swings both ways. I will often re-lock the banjo to get the handle out of the way.

The speed thing, the first time I have ever heard of that. You should give Oneway a call and get that fixed.

I have been turning wood for about 12 years now. I consume about 20 hours a week in front of the lathe making primarly bowls and platters. I keep thinking about making other "stuff" on the lathe, and ocasionaly I even get beyond the thinking part. But I take the most pleasure in bowls and platters. I have most every tool availble for the lathe but I am always looking for a new tool. More than looking for a new tool I am looking for a new hunk of wood. While a corner woodworker (sometimes called flat woodworker) can never have enough clamps, I find most woodturners can never have enough turning stock. The woodturning club I belong to has a Christmas party each year and part of that party is a "grab bag". We bring in a turning, that is judged by the people who come to the party. The people who make the top three turnings get prizes (like sandpaper or a tool). The real prize though is the exchange of turnings that comes from this colection of turnings. Some of my most cherished turned objects are the ones I have recieved from these grab bags.

>Keith:

The speed problem sounds (most logical guess) like a bad speed control potentiometer (that round knob thingy). They do go back, and there may be one spot where you turn the control too that is shorted, telling the machine to go full speed. Could be other things but as this control is used a lot, it tends to wear out first.

On the banjo, can you just move the banjo itself on the ways, point the handle more to the headstock (instead of 90 deg on ways) and they square up the rest with the work piece?

I don't have that lathe, but 99 percent of the time, I have my banjo about 45 deg to the ways to keep things out of the way.

>One of the things I did on my pendant controls was to remove the knob and put a piece of foam underneath it. It makes the knob a bit tougher to turn and avoids the full speed mishaps.

>Hi Don, yes, it may help a bit, but still in the way, as I try to keep the tool near the center of the tool rest. I'm usually forced to use the outer portions of the rest, which I really don't like to do.

>Hi Peter.....imagine this scenario...BIG day at the school, a grand-opening of sorts. All of those responsible for making the school happen are in attendance, all the board members, benefactors, invited guests, and the public. The turning center was packed, kids and adults. I am turning a 20" plus cherry bowl as part of the demonstration. With the lathe off, I answer questions and explain techniques. I turn the machine back on..Full Speed!Before I could shut the thing off, it had already shut itself down. The speed control dial was right where it was set.

Fortunately, I had secured the blank to a face plate with twelve #10 screws for safe measure.
