New from Carter Products
by Gord Langer
 
As summer begins to fade, many of us are getting back into our shops, following our passion for wood and starting to turn again.  Brian and I have had a busy summer thus the delay in producing another newsletter.   We would also like to thank all of you who continue to provide great feedback to us.  I was pleased to meet many of you in Tampa at the AAW Symposium where your kind comments on our newsletter were well received and appreciated.
 
Brian and I made the decision to clear out our Boring Bar System inventory.  We had lost our warehouse storage space and were anxious to get back into our shops.  Turns out this decision has provided us an opportunity to develop a relationship with a truly great company and the great people running it, Carter Products.  Over the past few months we have had the good fortune to meet the people who work for Carter, develop a business relationship with them and a good friendship.  Working with the folks at Carter Products, we have found them to be a truly class act.  We are pleased to announce that they have agreed to take over the manufacturing and distribution of our Large Captive Boring Bar System under the new name Hollow Roller XL.

In June of this year Lee Perez invited me to join the rest of the Carter Products team in Tampa to help launch their version of our Boring Bar System, now called the Hollow Roller XL.

It was great fun and I met a lot of new people including many of you who read our newsletters.   While the wood we had to use was less than great for deep vessel boring, the equipment performed great!  For those of you who may not be familiar with what can be done with a boring bar, we are re-running an article authored by Brian McEvoy on using the Large Captive Boring Bar for natural edge vases.

I am pleased to announce that the new Hollow Roller XL is now ready for sale and available for immediate shipping anywhere in North America.  We worked closely with Carter Products to make some minor but important improvements to our original design.  And of course the most important is that the Hollow Roller XL is now manufactured in the USA!
  
These are now available for immediate shipping:

Both Brian and I are often asked about two things to compliment the use of the Boring Bar System.  One is what kind of Steady Rest would you recommend?  The second, where to get a good laser system when turning dry or dark woods?  While in Tampa I was also able to use some other new products from Carter.   First was a laser system which I immediately fell in love with.  It is lightweight, easy to adjust and has very little vibration.  I used it every day in Tampa and really put it through its paces.  I knew I had to have one.  They weren't quite ready at the time but are off the production line now and available.  This system will fit not only the new Hollow Roller XL, but our original Large Captive Boring Bars as well.   If you have one of our original systems and are looking for a laser I can highly recommend this one.
  
This laser system built by Carter Products is also available for immediate shipping.  It should be noted that Carter has been in the industrial laser business for many years and has engineered a high quality laser including a convenient on/off switch located inside the base of the tube.
  
This is also available for shipment anywhere in North America and can be ordered from my website: http://www.langercraftworks.com/catalog/10?page=1

While in Tampa I also was able to test a great new Steady Rest.  This Carter product, called the Multi Rest, is available in two models.  One is for standard swing lathes and the newly introduced Multi Rest XL is for large swing lathes.  The Multi Rest has many nicely engineered features such as sturdy construction, easy adjustment and the one I liked best, the outer ring can be opened while on the lathe.  This allows for sanding of the work piece or any other adjustments you might want to make to your turning without taking the entire rest off  of the lathe.  For a great overview, check out the YouTube video where Jeff Folkert shows how the Multi Rest is used.

Here's the Hollow Roller XL along  with the Multi Rest.
  

If you purchased one of our original Large Captive Boring Bar Systems, or the new Hollow Roller XL,  don't forget we will still carry all our other accessories.   These include light kits, bulbs, extended reach cutter holder kits and our 17% tungsten steel cutters that do a great job for the interior of your vessels. 

  

The light kit is almost essential if you plan on turning thin with translucent timber.  The ease of gauging wall thickness will soon be apparent once you've tried out the light.  It's also a nice way to see what's happening inside your vessel.  A 12 volt battery charger combined with the automotive socket and bulb also will produce satisfactory results.  I like the higher light intensity that is achieved using either 18 or 24 volts.  The drawback to using the higher voltage is that the bulb life is reduced but the trade off and final results are well worth it!

SALE:

Purchase one of our light kits for $60.00 and get a FREE package of 10 bulbs.

Save $7.50

SALE:

 

Purchase our extended reach cutter holder kit for $45.00 and receive Brian's Secrets to Mastering the Large Captive Boring Bar DVD for FREE!  A $29.99 saving!

 

The 17% HSS cutters are essentially scrapers and very simple to sharpen with any bench grinder.  For consistent angles, a tool rest on the grinder close to the wheel is handy.  Just set the angle once to match the angle that is ground into the cutter. 

Join master woodturner Brian McEvoy from One Good Turn, as he shows you his secrets to creating deep vessels using the Large Captive Boring Bar.  Hosted by fellow craftsman Gordon Langer, from Langer Craftworks, this 90 minute DVD will show you the process from raw wood to sanded piece in easy to follow steps. Create amazing pieces quickly with these never-before-seen secrets from a master woodturner.

Deep Hollowing Natural Edge Burl with the Large Captive Boring Bar

by Brian McEvoy

 

In past newsletters and articles I've always hollowed green end grain timber, but occasionally I'm lucky enough to get my hands on burl of any species that is deep enough to turn vases with.  For deep hollowing burl I'd prefer to have burl that is dry and ready to finish.  Though as with any wood, green turning is much easier.  I find that green turned deep vessels are too difficult to re-turn once they are dry.  For this reason I try to use dry-ish timber; something I can turn, sand and finish in one go and by using the large captive boring bar, even dry wood isn't a problem.

 

The deepest natural edge burl vessel I've completed was 6.5 x 24 inches and was spectacular.  Maybe I'm just a sucker for burl but whatever size I turn I always find them to be outstanding. 

 

The process in this tutorial is similar to the one from our last newsletter, "Using a Laser to Measure Wall Thickness" but there are a few differences that should be helpful.

 

The finished piece is 8 x 9 inches and the inside depth is only eight inches.  I'm sure many experienced turners could complete something similar using conventional turning tools such as gouges or scrapers but this depth or deeper could be a challenge for most.  I'm using our six foot x 1 � inch captive boring bar because of its ease of use.  Even a relatively inexperienced turner could easily handle this rig.

 
   

 

 

 

 

Experienced or not safety is the number one concern.  Burl can be rather fickle to work considering you may have bark inclusions and weird grain patterns to contend with.  With this in mind I would recommend full face, head and lung protection.

 

 

 

Mark the centre on both top and bottom and choose the drive you are comfortable with.  I'll use the 2 � inch Elio Drive as I do for most of my turning.  This is a wonderful little tool that I believe every turner should have in their arsenal.  More information on the Elio Drives can be found at the end of this tutorial.  

Mount the blank between centers and secure the tailstock firmly in place. 

 

 

Using whatever tools you're comfortable with, true up your blank and start forming the shape.

 

 

 

I'll be remounting this piece using a 6 inch Vicmarc chuck available from Craft Supplies USA www.woodturnerscatalog.com  In past articles on deep hollowing I've always used a face plate to fasten the piece.  But because of the size and rarity of the timber I don't want to waste any material by screwing a face plate onto the block.  This piece started at 9 � inches deep and will end up at 9.  No waste...

.

 

At this point I'll turn a foot into the bottom for both esthetic reasons and to secure it into the chuck.

 

 

 

 

 

 

 

 

Ready to remount into the chuck.

Reverse the vase and secure it tightly into the chuck.

 

On rough surfaces I like to flatten the center three or four inches so the saw tooth bit that I'll use to drill out a depth hole will enter the piece smoothly.

I drill out a three inch diameter hole to within one inch of my intended inside depth using a Saw Tooth HSS drill bit available through Lee Valley www.leevalley.com .

 

 

 

 

 

  

 

I've drilled to seven inches with intentions of an eight inch inside depth.

 

 

 

 

 

It's important to set up your boring bar level and true the cutter to the center of the mandrel.  Once this has been done to suit your lathe and floor, only periodic leveling should be necessary. 

 

With the boring bar set up you can start hollowing.  As with any natural edge burl, particularly hard jagged burl like this Big Leaf Maple piece, things will be rather rough and noisy until you've cleaned up the top and are working in solid wood.  I would recommend ear plugs when you're working with dry timber.  The noise can also be rather intimidating.  Other than the noise you'll be amazed at how easy the hollowing process is and it won't make any difference if you're hollowing 2 or 12 inches off the tool rest.  The 50 pound weight of the bar will dampen most vibration and make deep hollowing a breeze.


 

 I like to use my low voltage light to gauge the wall thickness on thin wall turning to easily see what's happening inside.

 

 

 

 

 

 

 

 I've made a good start on the entrance in a few minutes of turning.

Another beauty of these boring bars is the ease of sharpening the cutter.  The HSS cutter takes a second to remove and with the grinder rest set at the correct angle, one or two quick gentle passes on the wheel and you'll be back to work.

 

 

 

 

Work your way down the inside for an inch or two being careful not to remove too much wall thickness.

I'm using a laser measuring system to gauge the wall thickness.  Refer to our December 2011 newsletter for more info on this operation.

 

 

 Calipers are an easy option when working on these shallow depths.

I've now reached the seven inch depth that I drilled and will start to make the smooth curved transition between the side and the bottom using the extra inch of bottom thickness.

 

 

Finish up the inside bottom.  You might be surprised at how smooth a cut you can achieve even cutting nine or more inches off the tool rest.

 

 

 

 

With the lathe speed turned down, carefully sand the inside.  I start with 80 grit and work my way up to 500.  There is no problem sanding the inside walls of a wide opening piece such as this.  I would recommend hand sanding the bottom with the lathe off.

 

 
 
 
 
 
 
The inside is now finished and looking beautiful.

 

 

 

Use whatever method of reverse chucking you're comfortable with to finish turning the foot and sanding the outside.  In my case I've used a spigot type chuck to secure the inside while the tail stock keeps the pressure on the outside; it's very effective.

 

 

 

 

 

Clean up the foot.

 

 

 

 

 I've changed the live center to a point so I can turn off most of the � inch nub.

 

 

 

 

 

 

 

Sand the outside including the foot.

 

 

 

 

 

 I use a palm sander to remove the small remaining nub off the bottom.

 
 
 
 
 
Completed piece ready for finishing. 
 

 

 

 

 

 

 

 

 

 

 

These are a few other samples of natural edge pieces turned using the Large Captive Boring Bar.  Note the dark piece that has been stained, adding a whole new dimension to the burl.

I would like to emphasize the simplicity and versatility of the Large Captive Boring Bar; the possibilities are endless.  There are many hollowing tools on the market that have a limited amount of effectiveness but I've always had certain trepidation with safety when hollowing a long distance off the tool rest.  The small diameter bars won't even come close to giving you the range of depth that this 50 pounder will.  I can't imagine a safer method of deep hollowing: they are virtually foolproof.  To get you going we have a great instructional DVD available on Mastering the Large Captive Boring Bar.  With over 90 minutes of instructional footage it will walk you through the whole process from start to finish, plus an additional 20 minutes of bonus features including a photo gallery, tips on using the laser to gauge wall thickness, steady rests and extreme boring tools.

I would also like to thank one of our readers who noticed that I used the words "mortise taper" instead of "*Morse taper" in the YouTube video; clearly my woodworking background came through.  Our Elio Drives have a #2 morse taper.  

*The "Morse Taper" was invented by Stephen A. Morse in the mid-1860's.  Since then it has evolved to encompass smaller and larger sizes.
