No, on my way out the door or I’d measure them. Edward has said he’ll release the plans — hopefully he’ll find time soon. Aren’t there dimensioned drawings in the assembly instructions?
While one could do one piece, not sure that it’ll really help — the machine is incredibly solid, also one wants to protect the surface of the waste board since it is a meaningful part of the structure (prevents lozenging if nothing else) and has metal fasteners pretty close to the surface. That said, I wish it had four additional holes at the corners to fasten a sacrificial waste board (and regret the engineering decision which resulted in it being such a lean purposeful machine that there’s no room beneath the Y-axis motor plates to run the waste board or stock — wonder how much stiffer, thicker and more expensive the end plates would’ve had to be to make that work — would it be possible to’ve stiffened the end plates further by putting vertical bends along the risers which hold the Y-axis extrusion?)
Thoughts on this (probably one wouldn't’t want to use all of these ideas (and some run counter to others), but it would be great if we could have a list of all the possibilities in one place — add the below to http://www.shapeoko.com/wiki/index.php/Workholding
- add holes for mounting a sacrificial waste board
- maybe make it a two / three piece system --- middle piece has a recess for the top one which is sized to perfectly match the cutting area and is milled as a pocket in it by the machine, thus tramming it
- put T-nuts in the middle piece, low enough to not be reached by the machine, high enough to be reached by not obnoxiously long/ expensive fasteners
- use plastic bolts from the plumbing section for fasteners
- rather than a grid use a spacing system based on phi (Golden Ratio) --- draw up in advance, even out the spacing to integral units, use a smaller initial measure along the short axis (or what will be the short axis when the machine is expanded) identify which sets of four corners match the work stock sizes one typically uses and assign work coordinate systems to them
- at each hole location put a right angle array of three holes spaced at say half-an-inch to allow one to use wedges for work holding
- arrange / align all holes so that one can use a piece of pegboard for the sacrificial piece so that one can just drop on the pre-cut piece and have the holes line up
- include holes for a centering / flip vise centered at the array (anyone have good plans for one?)
- include holes along the radial center axes left-right and front-back
Any other ideas?
(who still has to scrounge a sacrificial waste board, but had strange dreams about geometric shapes and proportions)
