I may or may not have found out how much the 9" sawblades from a local store are...

The design I have had a load of weight left, so I think I can get 2.5mm steel supports in weight although they're pretty cut about to be light enough. I'd use 2-3mm ti in a flash, I just don't have any. Need to do a complete CAD and weigh in before starting.

I've fully converted Gonzales to threaded inserts and barrelnuts. No more m4 tapped HDPE, yay. I did this for ease of maintenance more than strength; m4 straight into HDPE is probably stronger with a long enough bolt. I had to make 18 inserts and 8 barrelnuts and work around my own build tolerances from 11 months ago. Slow process!

Pic spam (although when bolted up the only visible difference is the change of bolts...)

Most of the inserts are m8 external and m4 internal:



I experimented with m6 external for the top and bottom panels to try and save a few grams. These aren't very strong but they shouldn't need to be (typical 9t drill pinion for scale):

The chassis as of this evening:




What's in those pics weighs 403g. I don't know what it weighed before, probably 20-30g less. I'm hoping with the other changes I still have enough left to stiffen the wedge.
