robust sells a toolrest dogleg

anybody ever use one?? what circumstances is it helpful?

will it fit any lathe with 1" post?
 
Charlie,

I have one by another manufacturer. They are helpful particularly for reaching into deep forms where you need to get your tool support close to the wood, where your tool presentation is not perpendicular to the wood surface. A shear cut on an interior curve is one such example.
 
Never thought about a Dog Leg for the tool rest. Well at least not one that's short and stout and actually works. I had one on my Nova but it extended out so far the tools had a tendency to chatter. My Dad's Shopsmith has one and boy is that junk. I absolutely cannot get a clean cut due to the vibration from this cantilever tool rest design.
The Robust one looks substantial. I will build one as soon as I have time and let you know how mine works.
 
I'm assuming, since I didn't Google up the word "dogleg" on the site, that you mean something like this 1" post sturdy extension. http://i35.photobucket.com/albums/d160/GoodOnesGone/OffsetRest.jpg Made by Delta, may still be available in places. Used to be at Packard, no show now. It reaches well where it has to, though my original reason for purchase, reaching around behind a turning on the 12" Delta with a too-short banjo, no longer exists.
 
I own that "Dogleg"

Hi Charlie - I own the Robust tool rest dog-leg. I got it to use with a sphere tool I have.

I also use it to get a little more depth out of a tool rest too.

It's very substantial or Robust and I haven't noticed any flexing at all.

It comes with a 1" diameter tool post.

The Robust Dog Leg can be found by clicking on "About Robust Tools" at the top of the home page and then clicking on "Accessories" on the left of the page that comes up. The Dog Leg is described at the bottom of the accessories page. From the picture, it seems to be much shorter than the Delta dogleg.

Thanks. Looks less like an extension than compensation for the toolpost being centered on the banjo. I sure like the offset post on mine. Glad to see most are going with a similar design.
 
Dog leg

I use the Robust dog leg when turning natural edged bowls (which I do a lot of) and can't get the tool rest close enough to the wood because the banjo can't be moved any closer or the wing tips will hit. The dog leg poistions the tool rest closer to the wood which reduces the fulcrum point.

Someone mentioned mentioned another dog leg that is longer. I don't think longer is good. I would be concerned about introducing too much vibration.

Have one of those box rests, don't use it because it's just not comfortable with the Termite or the cylindrical pointy gouge. Won't let you tilt the tool for optimum presentation. Appears most suited to flat stuff like scrapers.

If you can score the Delta I referenced above, you've got a treasure. It's as sturdy as your banjo to the very end of its cantilever. Allows use of your choice of toolrests, even if you have to cantilever them out as well. Disadvantage is, as you can see, the post assumes you've got a high banjo neck. The other weakness is that you may not have the strength in the way the banjo is held to the ways.
 
Mine is probably close to 14" but it is custom made and quite strong. I have used it for finishing the last inch of the top inside of large lamp shades I haver turned. What prevents mine from chattering is that the support underneath the tool support edge is a stout blade shape, and the 1 1/4 post helps too.

Who's the other manufacturer you got your dogleg from?

Charlie may or may not answer you since this thread is a little old. But this Charlie (me) has purchased a box tool rest/dogleg tool rest from Robust. It's called the Robust Box Tool Rest and several vendors sell it. You can also search for it here in the forums to read more about it. Robust sells them will different post lengths. I hope this helps!
 
The robust dog leg is a different animal - it has a post that fits the banjo with a plate on top that allows you to offset a toolrest about 3” from the post. The toolrest can be secured to the dogleg in any position If the rim of your bowl (as an example) rubs the edge of banjo, the offset allows you to move the banjo away while keeping the toolrest close to the work while the banjo is out of the way.

I actually bought mine in order to use a few smaller toolrest with posts too short for use when I upgraded to the larger Robust AB several years ago. I find it handy when it’s more comfortable to move the banjo’s position while keeping the toolrest close to the work.
Tool Rest Dog Leg
 
The VB36 has a similar set up which is very handy on that machine because moving the tool rest is a little more of a chore. The tool rest arm comes off of an I-beam from below. You have to crank a handle to loosen the arm then adjust, then crank back tight. VB calls theirs a Bennison tool rest and it's a fine design because one handle locks the rotation and the tool rest itself. The rotation of the post on allows you to make a lot of adjustments before having to move the main arm. On a Robust there are times when the stem of the banjo is too close to the wood depending on the style of tool rest you are using. The Robust offset would be handy. Everything Robust (Brent) makes is well thought out and well made.

My Jet 1440 came with one but haven't used it yet.
 
I have a tool rest that the pin is off set to one and its drilled out to use a type of Irons Gate by Phil Irons, otherwise my go to tool rest is curved about 12" long this can act similar to a dog leg when inserted
