Some of the parts, such as the engine which require quite thick material, I sliced because of length of my mills. Most of the other components didn't need to be sliced. I decided to use a silver nickel metal coating, but it's still pretty fragile, so I need to quit using mdf and figure some other material.
Fantastic work again, Gary! I really like this project!
Say, I just returned home from a CNC Conference where several folks use MDF to cut 3D models (in slices, two-sided carves, assemble, etc.). They are using MinWax Wood Hardener to "toughen-up" as well as seal their MDF models before filling and painting. One guy I talked to says he coats (or dips) his mdf projects several times, until the mdf can't soak in any more. Then he fills, sands, primes and paints the project.
I'll bet a lot of folks here on the forum have used the hardener themselves, as well.
I've used the hardener myself for miscellaneous repair of deteriorated outdoor wood in the past (I still have two partial cans of it in the garage), but never tried it on MDF projects. I certainly do have plans to try that now, after hearing their "testimonials"! I'm not sure if it will toughen-up extremely fragile areas of MDF sufficiently, but you might want to experiment with it some.
I bought the stuff from Home Depot before, but I think HD has discontinued MinWax products. Lowes carries MinWax products, though.
