Hi Bob,
I have a message on the main forum page, that this forum is closed for new support questions, since the new forum opened on the Inkscape website (a month ago). But I only recently learned that everyone can't see it, which is probably what happened for you. Me and maybe Lazur can help you here, but there are a lot more people in the new forum.
https://inkscape.org/forums/You can attach an image here by using the Reply button (not Quick Reply). Under the message box, click on Attachments. Or you could upload it anywhere you like, and just give us the link. Or if the image you want to show is on the internet somewhere, you could just give us a link to it. I'm not familiar with Alex Fox....I don't think.
But I think I understand what you're talking about. There is someone on the new forum, who is doing this same type of project. I can't think of their name....or what they call that type of woodworking, but it has a name. I'll try to find it later
If you are building up the same object, with smaller and smaller pieces, probably path offsets would work. Path menu > Inset or Outset, etc.
Edit
Nevermind. I found your other message with the images.
