A close up of the post.
Some customers want " hand turned" ( hard on the finger nails)!
and a new post I'm working on. Oh and there's my camera!

Stephen - Great work as always!

In your first pic, did you cut the flutes with a pointed form cutting tool?

[steve]

hi brad, thanks for that,
I used a side cutting rounover bit from Magnate. You need to cut into the side of the work. The bit needs to be centered with the center of the turning, I use part of the turning vector as the tool path.

Stephen, what Brad says, again!.....joe

Stephen - What are your general cut times for say a 2" to 3" turning that is 16" to 18" long?

I am running these sizes in about 1.25 hours using hardwood. I have been trying to get my times faster. I just wanted to see if we are in the same ballpark time wise.

Thanks

Hi Brad,
Seems to me it takes me 1:45 to turn a 3 1/2 or 4" square leg at 29" long. So that sounds about right. I could maybe cut faster but that's just harder on the bearings, not usually in a hurry for table legs. Also I only turn the last pass, I raster cut first ( as if it were a flat piece wraped around a post). I do a Z cut then a relief cut both with a 1/2" round nose,.2 stepover, .25 stepdown. then I turn the last pass of a turning file with a 3/16" or 1/4" ballnose. Is that about how you do it?

Stephen - I have been doing a 3D raster for the roughing pass along the length of the part. I set the toolpath in Aspire to leave about .04" of machining allowance. I use a 1/2" ballnose, cutting .25 deep and 0.2" stepover.

For the finish pass, I also use a raster along the length of the part. 1/4" ballnose with a .015 or .02 stepover.

So, my Y-axis travels the full length of the part, pauses, indexer turns very small amount, Y-axis travels to the other end, indexer turns very smalll amount, repeat, repeat, and repeat some more.

I just use the standard roughing and finishing routines within Aspire.

Our terminology may be different, but I think we are doing it pretty close to the same way.

Yea same process.

Love your stuff, as always!
