MDF NEMA 23 Motor mounts

**Ross77** · 08-08-2010

Secondly, I look at these mounts as a metal studded rod mount with MDF spacers, the metal rods (in tension?) provide a lot of stability, the MDF (in compression?) doesn't really have any where to expand into.

Correct, which begs the question is all that mdf needed? I would have just used the front and back plates and then spacer tubes on the threaded bar. But as John said, I think analysing MDF to this degree is unnecessary as it will typically be a first build.

I really like the design process. Now you mention it Ross, it probably isn't. I like bolting through a wide face of MDF because it adds plenty of torsional stiffness, but there probably isn't the need for 3 closed sides. If I made the spacers separate (2 on each layer) it'd save some raw material, a tiny bit of cutting time, and some weight. Mk3 on the way... :)

Thanks for the complement Barry...
