I have a project coming up where I need to make two matching tapered columns, but alas I do not have a lathe. I wanted a way to create them easily and repeatability was important – here is the jig I came up with.. A box.. On the front end I have a vertical adjustment to set the diameter at one end and a way to turn the work piece. At the other end is a sled of sorts that can be adjusted based on the length work piece needed, also with a height adjustment.
I can now take a length of wood, and cut it into an octagon on the table saw, drill center holes in each end (and a keyed hole in one end). I put that wood in the jig, and run my router (with a wide mortising bit) up and down the box turning the wood a little each time, and end up with a column. I made the front and rear pins adjustable in height so I can make any size column up to about 5” round by 40” long. To give the column a taper, I just set the rear center pin slightly higher than the front center pin. With a core box bit I can even use this to make flutes in the columns after I have rounded them. I have not done yet, but plan on drilling equally spaced holes in the front round to give the handle indexing properties.
In the pictures you can see the before and after test piece I did.

very well thought out ,
and executed !
years ago i had to make a teak spiral stairs for
a large pleasure craft ,
and made a box out of ply like this ,
but without the adjustments .
i turned a post 5”x8’ for it this way .
the word got out all the way to miami ,
and boatbuilders were coming to see how it was done .
there was 1 lathe long enough in miami to do this ,
but it cost a fortune .
i sure like yours ,
thanks for sharing !

Necessity is the mother of invention, and that looks like a jig you could do some really neat designs with when using different router bits (I’m thinking a chamfered edge with flutes on it would be easy to do with this jig, or at least easier…). Definitely favorited :)

Extremely cool with good adjustability.
Even better than a lathe considering controlability of depth of cut & the high number of router bit profiles available.Also the shavings should mostly be dispersed into the jig itself unlike a lathe where shavings & dust can shoot everywhere.

Awesome jig! I gave my lathe to Eric, but this will help immensely. I also highly approve of your router selection. I also have a Hitachi M12V 3.25HP.

Thank you everyone for the kind words.
Hey David65, I had considered adapting it for spirals. I am certain I can make it work with some pulleys and a cable attached to the front round and the router tray.. Since time is always a premium for me, I will wait till I have a project where I have the need.. ;-)

You inspired me to do something of the sort. I have gone to several of the woodworking shows here and every year they have a jig that runs $$$$$. With what you have posted I can run with it and adapt to over come the $$$$$ and get the same affect and run a spiraled leg. Thanks for the starting point and idea. BTW what unit are you in or are you out.

I missed this!
What a great idea. You might see I’ve been doing canes and walking sticks and this would be a big help. You could put a long one together for all sorts of things. Would save a lot of time removing material. Plus custom dowels are a good thing to be able to produce. Very cool…...................

Great looking jig. Very nicely done. I can see a lot of ideas coming from that jig.

Hey David65,
Regretfully, I have never been in the military. SgtSnafu was my online gaming handle from days gone by, and it just stuck. I have another jig to post, it is to help me take a 6/4×6” x 36” board and cut a 12’ radius curve in it – On Edge !! I will post it, after I test it !.. ;-)

That’s OK I just put Two & Two together and ended up with five. No just kidding my youngest brother was stationed at Ft Bragg NC and thought you might have been. Can’t wait to see the new jig. I have a Craftsman/Mission style rocker I am finishing up so when I am done I’ll post it.
