I think Neppo1345 has come up with the best solution yet, IMHO. I did a quick drawing in Fusion 360 of a slightly altered version using 5/16 aluminum plate. Since I don't have the SO3 yet, I can't comment on how effective his design is, but it sure looks like it would help a lot.

Good Job, Neppo1345!

That's actually pretty slick. Stiffens the plate and supports the spindle mount too.

Nice!

HDVideo, I like that take on it! :D

I thought about extending mine down past the mount as well, but the 1/4 inch plate I had on hand wasn't long enough.

I cut my LH plate cut Wednesday. Didn't make any mistakes with the CAM this time, and played around with some new feeds and speeds that left a very nice surface finish.

Currently have the Z axis torn apart all over my bench with the hole locations marked out; got too tired the other night and had to call it quits (didn't want to make another rushed/tired mistake like I did with my CAM on the RH plate).

Planning on finishing it up this weekend...if it works I'll post up the DXFs.

Thanks Neppo1345, you have a good design there. How many screws did you use to attach to the plate? I put three holes for M5 tap on each. Was going to use four, but spacing didn't work out right. Attached is the Fusion 360 file for my variation of your design. Eager to hear how it works out if anyone uses it.

Well, it wouldn't let me attach the f3d file. What file formats are acceptable?

From memory, the forum just does a check on the filename extension. If you rename it to something it's happy with, that should work. Maybe .txt or .zip?

Alternatively, @twforeman might be ok to add .f3d to the list of accepted filename extensions. (?)

The forum should accept .f3d files now. :)
