Topic tags/keywords: question

I’m designing a couple of projects that are made from 8/4 or 4/4 stock, but have some engineering challenges. I’ve made models in sketchup, butI’d like to see how they are in real life. I’m thinking of making a full-size model out of 2×4’s/6’s. I want to check things like balance and stability, so I want to use as close to the real thing as possible, but also something I can do quickly.

Anybody ever made a full-scale model/mockup out of construction lumber?

Nope, but I’ve seen plenty of people do it. That plus particle board, foam and all sorts of other rigid and semi-rigid materials. It’s unlikely you’ve ever been to Michael Fortune apprenticeship class at Marc Adams School but if you have, you’d be amused at the total chaos of wood scraps and foam strewn about the students benches.

The goal is to just stick parts together with screws, hot melt glue, tape, wire or whatever it takes to hold the parts in place while they’re analyzed.

I have. I was making my first 8 sided pencil post bed and wanted to test the jigs I had made to make sure they worked. I used glued together pine 2×4’s milled down to spec and it worked great! Not cheap but one hell of a lot cheaper than trying it live fire with very expensive cherry 12/4”

I’ve made some actual furniture out of construction 2×4s and it works just fine. I can’t imagine how it wouldn’t work for a mock up.

I tend to buy rough lumber in large quantities. When I want to mock up a chair, I just use the second quality hardwoods. There is always some stock with cracks and knots that is destined for the wood recycler anyways.
I think chairs are the best place to use prototypes, because it may look right in a scaled drawing… but one sit will tell you it’s not.

Case goods are easier to mock up with cardboard.

I wouldn’t do this in most cases, but I did try it yesterday and it is a ball. It’s amazing how fast I could build something with soft wood and no concern for detail. I put together an accurate full-size model in about 4 hours-it will take me a couple of weeks to build the real thing.
