SWMBO would like one of these for Xmas.   Wondering the best way to do it, without having to spend half a day making a jig.   My initial thoughts are to cut a half-hexagon profile, then even out with a plane and finish up with a belt sander.   Other ideas?

 

IF you have a lathe.....

Make two square pieces,  glue together with a sheet of paper between them.    Turn  into a cylinder.    Sand smooth.    Remove from lathe, and split them apart along the papered glue line. 

 

Option 2;   Spokeshave it  round.  

rough hex cut, final shape w/ a convex spoke shave or profile plane and then smooth to happiness w/ your ROS....

too easy to make flats on it w/ a belt sander..

straight edged/bladed cutters will tend to to leave lots of ridges...

It looks like a half round. I would do it like Steven suggested, except I would probably use turners tape. A well known technique.

yeah, well I have a lathe on the Shopsmith.   I maybe used it twice.  Hated it both times.  Option #2 sounds good.

Well, if you could find a tree, just the right diameter and had a chainsaw...   

 

Just kidding. For me Steve's comment would be my preferred method.

Bandsaw is the alternative

What does it do?

 

If you roughed shaped it on the band saw and refined it some with a plane and or spoke shave you could sand it with a long piece of emery like you were buffing a shoe when polishing it.

Not being a turner, I would do like you suggested and cut the hex on the table saw then use a block plane or rasp  to round it and then a sanding belt by hand to smooth the marks out. Might make a template out of ply wood for a gauge.

The lathe is going to give you the most consistent profile (I think). Maybe sub it out, after trying some of the other approaches (if they don't work).

My wife does quilting.   She says it's to put a seam over it, fold the allowances over and press it down with an iron.   It gets the seam flatter.  Happy wife, happy life.

You can buy rod at 1.5" dia, then screw/glue it onto a 1/4" flat board, maybe 2" wide (maybe flat one side of the rod first, 1/2" wide flat).  You end up with a sharper curve top (the sample looks maybe 2" diameter?), but it will expose the seam when the quilt is laid over it.

short section of large diameter hand rail...

large diameter rolling pins...

come nominal 2'' dia and up to 3.5'' diameters..

need longer.. dowel them together...

pric3es are as low as 8.95$...

resaw or add a base plate...

then what the other guys are saying about creeping up on it with shaves scrapers & planes

Yep, pretty much got it done in 20 minutes or so.   Marked out octagon, cut corners on tablesaw, shaved down with a block plane and sanded out facets with ROS.

Easy peasy. Way to go.
