Few months ago I built an octagonal table (not my design) and did not assemble it because I was not satisfied with the legs. I also had problems with the finish.
Problem #1: The finish
The Wood used is white oak and because it’s so porous I never got a flat top.
I kept builling layer of polyuratane but that did not work.
I Sanded off the finish.
I then put on 1 layer, leave it to dry, sand it down but not completely.
Put the second and the third following the same procedure.
That kind of filled the ravines but it still was not really good.
So I stripped down and applied a mixture of talk powder and poly.
That was disaster. I filled the pores allright but I ended up with a white ghost color all over.
I spent a lot of time sanding my top to clean it.
I guess I needed to treat the talk powder with something (?) to get rid of the white color.
I the learned of crystalac wood filler thanks to a review on LJ; I bought it but have not tried it yet.
Problem #2: Pattern routing the 4 legs
I use my template, trace it on the leg then scroll saw the inside (also jig saw).
I then do a pattern routing on the router table.
I got 3 legs that chattered on me I guess due to vibrations.
The first picture (without the top) shows roughly what the base should look like.

Parts of broken legs
I was using :
New strait spiral bit 1/2” from whiteside
Porter Cable 3-1/4 hp router set for 19000 RPM (also tried 23000)
I still got 3 legs chatered.
I try “small bites”, upcut but that did not work.
What is the best way to patern route those legs on the inside. Although the wood is kind of thin after the scroll saw, there must be a way.
Hand sanding is tedious; I did hand sand the first one to make the template.
Comments / ideas highly needed!
