Hey Craig. In your design you may want to consider 8020 extrusion. I found an eBay seller with IMO reasonable pricing. I admire your desire to have it be all metal and shiny but metal is expensive. While We should aim to have the main supports be metal for stability, and possibly area, reasons it might be best to have the actual bed made from cheap lumber so if/when people make cuts in the wrong spots we don't send spinning metal bits flying or dismount a powered circular saw from it's cradle. Here's a quick glance at 8020inc's stock of factory second extrusion and bearings: 8020 aluminum extrusion 1010x60" $15.75 + $21.30 S/H High cycle double flange linear bearing 40S 40-3834 $20.99+$12.25 S/H T-Slot Aluminum Linear Bearing 15 Series 6815 $35.72+$11.78 S/H 1030x72" T-Slot $23.76+$22.96 S/H Ebay 8020inc If you aren't aware part numbers are in the format of LlWw where L and W represent the inch equivalent and l/w represent the decimal place ie; 1515 is 1.5" x 1.5" extrusion. For laser guidance sparkfun has diodes fitted with line forming lenses for about $9, I've seen them cheaper on DX and I'm sure ebay has them too if you don't mind waiting for them to get through customs.
In response to space considerations of a panel saw: I am imagining one similar to those operated at the home improvement stores where the panel is held at a steep(75-80*) angle. In this configuration even when in operation they only take up 15-25% of the area of a 4x8 ft sheet. So 32sqft turns into 8sqft. If the support arms are made to be collapsible this is easily something that could be pushed behind equipment when not in use. That said, if one is bought/constructed/legally obtained where we put it when not in use should be considered before/if we invest. regards, Andrew L On Wed, Apr 2, 2014 at 6:18 PM, Craig Bergdorf <[email protected]> wrote: > About that link: > If someone handed me $600 and said "make this" I would most likely be > delivering it in a shiny new $500 work truck :) > > On use of the saw: > Count me as once a month > > Agreed if it was built well (machined mounts, steel or at least allthread > construction, 0 wood used to build it, a laser pointer on the front of one > of our circ saws), it would have a high wows per $ factor > > It sounds like fun to design, so I'm gunna over the next week. > On Apr 2, 2014 3:27 PM, "Justin Herman" <[email protected]> wrote: > >> I think a panel saw is one of those things that MAY not get used every >> week BUT when it is used it will make things VERY easy.
