We figured out nice feet on the ironworker we're building in the shop. Add them to the model, BOM, & assembly instructions.

They're 2 hole tubes that bolt along the bottom below the pivot plates. They don't look like much but they made it almost impossible for Marcin and I to tip over the machine.

The new parts are:
2 x 2 hole tube (one on each side)
2 x 21" x 1" threaded rod
4 x 1" washers
2 x 1" lock washers
2 x 1" nuts

• Add 2 more pivot plates on the outside of the pivot on each side.
• Add 2 4" tube cubes inside pivot to keep pivot plates from bending in.
• Redo spacers to not have gaps under pivot plates.
• Grind down pivot plates to redo spaces between them.
• Add bolt mechanism to shaft to pinch everything tightly.

If this all works well, update 3d model, bom, and assembly instructions accordingly.

I've got some editing to do and uploading of new pictures.

Also need to add section on calibrating blade gap.

The dozuki guides use 6" bolts in many places which may not have quite enough room when we add lock washers. Update all the guides to use 7" bolts instead of 6".

Once the guides are updated, we'll need to regenerate the bill of material.

We got some burping on a few of our big cuts. We think that's because the blade gap gets a little wider at the end where the burping happens.

Marcin's going to replace those spacers today and recalibrate the blade gap and we'll check if that solves the burping.

Once this is done, we'll have to update the docs as described in #5.

Some parts list 1" x 7" and some like 7" x 1". Ditto for values other than 7". Make a pass through all the dozuki guides and change them all to list the diameter (1") first.

Here's a nice issue about blah blah. Epic.
