Turning Between Centers Poll

[JBCustomPens]

Hey everyone,

Here is a poll for those who turn between centers. Do you use bushings, or not?

 

[johnnycnc]

I do use bushings, yes.

 

[desertrat]

Always use bushings

 

[ldb2000]

Once again you don't have the right or enough questions in the poll . I round my stock between centers then drill on the lathe , THEN use stock bushings to turn to final size and remove them for finishing . Most who drill on the lathe don't use bushings for rounding the blank .

 

[skiprat]

What kind of 'cutting' can you do while using any type of bushing?

I make my own bushings.

 

[NewLondon88]

Skip makes my own bushings. :biggrin:

 

[OKLAHOMAN]

I use Johhny's bushings center to center to size along with calipers, then turn around and put on my other lathe with Johnny's sanding bushings for sanding and finishing.

 

[mbroberg]

None of the above. I do use bushings sometimes, i don't use bushings all the time. When I do use bushings I use JohnnyCNC's bushings.

 

[JBCustomPens]

Thanks for feedback!

Just to let everyone know, this is a multiple choice poll.

 

[mredburn]

I use generic bushings i make my self.

Butch,

I must not be in the most catagory... I drill on the lathe, but it doesn't matter if the blank is round or square, I drill it. I then proceed to turn it with bushings. Even if it is square.

 

[ldb2000]

That was why I said MOST . I know there are some who drill square blanks , I just find better accuracy drilling a round blank .

 

[jocat54]

I turn to round with no bushings, then drill (collet chuck) and then bushings to get close and finish with calipers.

 

[Rfturner]

I currently use mainloy stock bushings but I have made my own from aluminum and corian because I turn on a mandrel, when I get more money I plan purchasing a few more goodies to be able to do between centers faster and safer

 

[bitshird]

JB Your question leaves out certain options, like butch I round with a dead center, and cut some styles with bushings which I've made and some I don't use any bushings at all just a dead and live center and my Calipers. You need to adjust your Poll parameters like my Grand dad said they's 4 or 5 different ways to skin a possum.

 

[cozee]

I have yet another method. I make my own bushings that are designed to fit the tubes for turning between centers with just enough shoulder to keep them from slipping into the tube. Blank size is obtained with calipers.

Yea, what he said...

I 'm new to TBC and thought I had come up with this idea on my own... Seems like an ideal situation, since you only need one set of bushings per tube size...

I had thought about bringing it to Johnny with a small extra, "washers" that could be put in-between the bushing and the blank that were the sizes for the kits, to help you get close to size. They'd be small, inexpensive pieces, they could be marked on the flat parts with which kit and location they were, you could use them to get rough size, then remove them for final sanding/finishing, and there would be much less waste from wear on them. It would be a great, inexpensive, and easy to store method for less popular kits...

 

[DurocShark]

I use home made cone bushings.

 

[Brittleheart]

I am in the "not enough options" camp. I also vary my technique according to the pen I am making, but generally drill blanks before rounding them and use stock bushings between centres when I am not using a mandrel.

 

[Texatdurango]

I used "stock" kit bushings a few times and realized that I had not improved my accuracy one bit so using a 60 degree center drill, I lightly drilled the end of the bushings so the live and dead centers would have a place to seat snugly.

I used these modified stock bushings for a while and even got into some heated discussions over the need for "special" bushings.

Well, Johnny and I swapped some information back and forth and after using a dial indicator on several setups and checking the run out and trueness using a variety of bushings from "pure stock" to Johnny's bushings I realized there was no getting around it. If you want accuracy when turning blanks between centers, why not spend the few extra dollars on some bushings which are designed for turning between two centers?

Can you still slap two "stock" bushings between a live and dead center and get a round pen........ yep, but just don't put a dial indicator on your lathe and check trueness afterwards! :biggrin:

Once you start seeing results in thousandths of an inch it's hard going back to eyeballing things!

yeah, what he said +1

 

[holmqer]

I'm one of the make my own bushings types. Steel for turning and Delrin for finishing.

 

[philkessling]

I use johnnycnc bushings for turning. Turned down some of the Delrin bushings for finishing.

 

[Mr Vic]

Bushing? That's what my wife does when she heads into the mountains with her trusty shovel.....Not a bush is safe!

For a quickie slim line it's the mandrel and stock bushings, finishing is with coned UHMW bushings. Something to sell or custom is stock bushing to near size the between centers and calipers to finish. My drive center is a tapped piece of UHMW turned conical.
