I want to try to do a spiral inlay on a desktop, but just wondering if thats going to lead to problems w/ the expansion/contraction of the table top. Any one have any thoughts?

How large will the inlay be?

I’m thinking 1/4” or 3/16” padauk that spirals around 30” of a walnut table made of 4” wide x 1.5” walnut

Chances are you would have problems if you lay in the paduak cross-grain to the walnut. If you can arrange the inlay so that its grain orientation matches the walnut, you would probably make out ok.

Since your inlay pattern is curved, and paduak isn’t particularly bendy, you will either have to work in segments, in which case you can cut strips of paduak to approximate the grain direction of the walnut around the location of each segment.

The other option would be to resaw thin (<1 />) sheets of paduak to use like veneer, cutting the paduak sheets to exactly match the spiral while keeping a match to grain orientation. Easier to cut up the paduak first then incise the walnut to match the paduak, than try to match the paduak to an existing curved groove in the walnut, IMHO. YMMV.

Ever considered using veneer for the whole thing, commercial or shopmade?

Iguana, thanks for the feedback. I had a pile of free walnut that I got, so am really just playing around and experimenting w/ a few ideas I’ve had rolling around in my head. So no, I had not considered using veneer for the whole thing….if this idea doenst work out, not the end of the world.

I have a very definite curve I want to follow, so the plan at this point is to cut the spiral into the walnut and then see if I can get 4 strips of 1/16” padauk to bend/conform to the spiral. I’ve been reading a bit about soaking/steaming/heating wood to get it to bend, so considering that as well.

Have your say...
