Need advice

How can you tell Chris that it's not the same distance around?

Just a hunch from the picture. If it's just an odd camera angle, then no worries. Have at it :-)

Wonder how much mdf I'll go through before I get it.

Read Chapter 1 of Eric Newton's build manual thoroughly and you'll get a good understanding of the processes involved. You said you have it a while back. Definitely read it. Did I mention you should read Eric's manual if you have it? Chapter 1. All of it. Twice even. Don't need to print it. Just open the PDF on your tablet or computer and read it. Lots of great photos and step-by-step info. With that, my stuff may make more sense.

Also watch that whole video that was linked a few messages up. Very valuable insight.

I've had to redo some forms. You can get a lot out of one sheet of MDF

[MNBenny]

I'm thinking about buying a big sheet of plastic cardboard and do all the patterns before committing them to MDF. It might ad an extra step but at least I won't burn through the MDF.

That's a good choice. Likely cheaper and less effort before cutting the thick expensive stuff.

We took one of the MDF patterns and traced around to see if it was consistent. According to dad at least he says the flange is consistent.

Sounds like you're in good shape :-)

Would Home Depot or the local ace hardware have bushings?

Bushings for what?

[MNBenny]

To stick in the jig holes to keep everything locked in place. Won't the holes start to wear to big over time?

Believe it or not, not too much. When I was drilling through mine, they got a little bit bigger, but not significantly so. Since the number of pieces your building is far less than a factory setting, the wear is negligible. I cut four wings' worth of ribs from my first set. Drill carefully with a drill press, not a hand drill, and the hole enlargement will be minimal.

[Chris In Milwaukee]

The only thing that would benefit from using bushings is keeping the holes from enlarging while drill jig holes. MDF is tough stough, otherwise. Chapter 1 of Eric's guide shows him using bushings made from small-diameter 4130 tubing. I've had no luck finding a similar material at any hardware store or home center.

So do you think it would hurt not using them? Also being that I am using a router do I still need to drill holes in the inside corners?
