Ebay Boring bar - Good deal or waste of money?

Nice photo!

Is that a Bison chuck? Tell us more about your setup 😉

OK. Here's the bench. Yes, it's a 6" Bison and that's your fault, Will, because you said it's the one to get. :laughing: I'll buy anything that the gurus on this forum recommend - after all, I'm a beginner and don't claim to know much.

Seriously though, I'm grateful for all the good advice and info that is offered here.

That's a good idea, Barry. I was stumbling in that direction last weekend when I made this light:

I made a plug to match the 45 degree slope on the inside of the bezel:

This let me mount the part in an indexing fixture that has a dead center smaller than the aperture in the bezel:

Now that I think about it, I didn't need to put the 45 degree face on the plug. It positioned and held the part just fine but it would have been better to just turn a cylinder to slip fit through the aperture with a shoulder to hold it as you suggest. So, now I know! :thumbsup:

Man, that is absolutely beautiful - nice compact setup you have in there :twothumbs

... I was stumbling in that direction last weekend when I made this light:

Now, come on, we need "more" information on that little beauty. Or like Will would say, we need more photos!!! :devil:

Is that a powder coating finish on the light?

I think there has become quite the common saying in this sub forum & is my motto now.... "Blame Will" or "Blame Barry"! That has become my reasoning. :nana: :wave:

Don't look like a beginner to me! Awesome setup up! Is that a DTM QCTP I see?

 

[precisionworks]

It positioned and held the part just fine

And that is all that matters. There are dozens of different ways to do any one op, but the one that's the easiest (while still maintaining safety) is the first choice. Awesome light :thumbsup:

Well, you're right, I'm not a beginner. Those were my 2nd 3rd and 4th flashlights. :laughing:

Sharp eyes! Yes, it's a DTM AXA. I used a piece of 12L14 to replace the hex head tightener sleeve (or whatever the correct name is) with a lever and ball so I don't have to grope around for a wrench all the time - this is a big improvement in terms of convenience.

Yes, and the point on safety shouldn't be overlooked in this instance. That big bullnose works fine to hold the part but it can get perilously close to the tool and holder when working in close on small parts. Much better to use a custom plug and a smaller live center to leave more space between things that shouldn't touch.

One other item you'll want to pick up some time is an extended point live center. The CNC users are responsible for this adaptation of a standard live center, as it give a tool extra room to work without hitting the center. Everybody makes one, and Bison probably has one on sale now, but there are other good ones. Look at this one from Royal, as most look similar.

I've seen that configuration in passing and was curious about it. Thanks for the link to the Royal page, which clears things up.

That one is only $579 for MT2 - maybe I can Google around and find one that isn't cheap import junk! :sick2:

Although not a Royal, Skoda has one for just under $200.

The same one costs just under $220 at MSC but if you wait for a 35-40% off day you might be able to get it for well under $150.

Not sure if those go on sale at Enco but I got my Skoda for about $80 with free shipping.

Another to look at, made in USA but no brand listed:

[saltytri]

Now you're talkin'! That's more in the home hobbyist price range, and USA to boot. Thanks for the tip.

One other center worth looking at, if the $222 price tag is within reach, is the Royal Versa Turn. It combines an extended point center and a bull head (pipe) center into one unit.

It could be worse. They could be telling us to buy some thing really expensive like Ferraris. 😱

I have this one. It works out really good for me. I was told it can't handle very high load. But what I'm doing (flashlight body), it is fine.

I got it from MSC with 35% discount, came out cheaper than ebay price.

 

[precisionworks]

I was told it can't handle very high load.

That's actually a pretty stout center. Royal rates it for a 330# load & 2160# thrust. I didn't see many of their products that had a higher rating.

They are excellent to work with if you ever damage or wear out any of their centers ...

Show off! Again, really great work!

I really like those DTM tool posts. Had my eye on one ever since I got to see one in person, they look very high quality. How do you like it? Please convince me to get one. :laughing:

 

[saltytri]

If you want a DTM, better move fast! They're out of business but there's a guy selling the NOS on eBay. It was a little cheaper than an Aloris but not enough to get excited about.

I do like it, but then I've never seen an Aloris in the flesh. I have seen and used Phase II AXA wedge and piston and the DTM feels like a Leica compared to a Yashica (boy, am I ever dating myself!). The lever for snugging it down on the post is a huge convenience and well worth the small effort to make it up. In short, I'd certainly do the whole thing again.
