How to make square into round...?

[Mike Worrall]

I'm needing to slide the round 'kranse iron' or 'eyeband' in the photo onto the last 6" or so of the square bowsprit (3.5" X 3.5" Doug Fir).

The ID of the kranse iron is 2.25", the bowsprit is 7' long.

Needing to know how to make a 'square' member into a partial 'round' member...?

I'd like to be precise, meaning I'd like to finish with a truly 'round' 2.25" on the forward 6" of the 'sprit.

Any ideas on how to go about it??

Its not that hard. You just knock off the corners until you get it round. Start with an octagon, then turn it into a 16 side, then 32. After that its pretty easy to blend

Another approach if you have a quarter round shaper bit of the right size...
