Where do you get wood in those dimensions? There is an exotic wood place here and they have such odd dimensions I haven't got the foggiest idea how to work with it.
You have a good point! I don't know of any one that offers Teak in specific dimensions. What you would have to do is find someone (like me

) with a fully operational woodworking shop in their basement or garage, etc. What I do is buy raw lumber, boards mostly, and process them to the size I need. I can even handle small logs if they are special enough to fuss with. I’ve helped a few “woodshop challenged “ audio Diy’ers in the past. Not ready to offer my services professionally yet. I have a 120yr old house that needs my attention first. However I have taken on I few small projects and bartered. Here is a pic of a small project I helped with

I made the legs out of walnut in trade for help with some electronics projects
Let me know if I could help
