I recommend revising clamp jaw and vise design, on the following fronts:
*Clamp block should be as large as possible while retaining full range of motion; this gives more surface area for the jaws to mount to, increasing likelihood of remaining square over time.
*Vise blocks should close all the way, or at maximum 1/4" away.
**May need to make vise blocks from multiple pieces so they can nestle above the center piece of the vise.
*Jaws should be sliding if possible--this will also go towards keeping it square
*Slots on jaws for bolts should be centered-goes towards keeping it square
*Slots should have radiused corners; no endmill is capable of milling a rectangle.
*Handle seems to be a waste of material. I see 2 options:
** Machinist style vise handle (look on the mill)
** Table vise style, with sliding rod.

This is a page to review V1 design and 2d fab drawings.

Design

General

  • Can you put in threaded rods and proper bolts? I don't need it for building, as I will be able to consult you if I have questions. However, anyone simply looking at the cad will have no idea of how the thing works.
  • Are there any mechanisms in place to change the speed of the blade? For optimum cutting, the speed needs to be variable so that we can have the proper cutting speed for varied materials.
  • Should be a grease nip around rod for swivel which allows lube.
  • Any markers to tell you what angle the blade is at relative to vise? Protractors are a pain in the a** for fabricators. Markings will be more convenient. Stickers are sold online for stuff like that.

Vise

I recommend revising clamp jaw and vise design, on the following fronts:

  • Clamp block should be as large as possible while retaining full range of motion; this gives more surface area for the jaws to mount to, increasing likelihood of remaining square over time.
  • Vise blocks should close all the way, or at maximum 1/4" away.
    • May need to make vise blocks from multiple pieces so they can nestle above the center piece of the vise.
  • Jaws should be sliding if possible--this will also go towards keeping it square
  • Slots on jaws for bolts should be centered-goes towards keeping it square
  • Slots should have radiused corners; no endmill is capable of milling a rectangle.
  • Handle seems to be a waste of material. I see 2 options:
    • Machinist style vise handle (look on the mill)
    • Table vise style, with sliding rod.


2D Fab Drawings

  • Wherever possible, convert measurements to English units-- FeF Mills are in English units, so the conversion will need to happen either while milling, or on the drawings.
  • Specify tolerances on all drawings
  • Is there a cut list?

Base to Vise

  • Does the bottom side of Fixed Block need to be machined flat? Same with top of base flat. If so, specify in drawing and instructions.
  • Extend baseplate so the swiveling blade mount will always be on plate.
  • Need diagram to show where to weld "long spacers"
