My tubing is 3/8" vinyl ($15/100' at Menards) With a recycled refrigerator compressor I can pull about 25" of vacuum almost silently. -- Morris Dovey DeSoto Solar DeSoto, Iowa USA http://www.iedu.com/DeSoto/ |

The better ones like Staron and Corian don't. Type of refrigerator doesn't much matter - nearly all of the compressors used are made by only a handful of companies. Hmm, filter - I folded a piece of Kleenex until it was about 1x3, then folded that over the cut end of the output tube so as to catch excess oil being pushed out of the beast. The input side has a 10' length of vinyl tubing which seems to catch the dust before it gets to the pump. That's not a particularly razzle-dazzle filter, but I haven't had any problems in the five-plus years I've been using this compressor (which came out of a refrigerator more than 20 years old). Since I put that one into service, friends have brought in three more compressors, so I haven't felt any need to coddle the thing. Pedestals should be easy - I think I'd just make 'em out of 4x6 cut-offs (or glue up some 2x6 scraps) and screw the pucks to those. These are exciting times.

I guess it is all about data points. So much to learn and loving it. How're your programming skills? If you examine toolpath cutting commands (movement with tool below surface) in groups of three, you can eliminate all points that don't lie more than a pre-selected error value (say, 0.001") from a straight line joining the endpoints. If you want to further refine what's left, you may be able to do a fair amount of reduction by fitting arcs to groups of three or more points and use arc-producing movement commands. I played around a bit with code that re-ordered toolpath segments to minimize waste tool/spindle movement and for /some/ files it made a big difference in machining time. -- Morris Dovey DeSoto Solar DeSoto, Iowa USA http://www.iedu.com/DeSoto/ |

Exported as .dxf, .eps. and as an image file (jpeg) Then I imported into VcarvePro via .eps, .dxf. and traced the image file. I also created the same oval within VCarve Pro. The file sizes were different, but not as significant as the estimated machining time associated with each type of file. The trace off the image file was close to an hour, the same oval in VCarve was 3 minutes. Same oval. |

Sounds like the the cad was generating way more points than necessary, and there may be a precision parameter that you can adjust to reduce the number of points. In my DesignCAD package, I can (very carefully!) sometimes use the "smooth" command to reduce the number of points. You might experiment if you have a similar command. A while back I cut a 48x24 elliptical template for a local cabinetmaker (for a conference table inlay) and still have the file: 1 command to position spindle 1 command to lower tool to cutting depth 1440 straight-line moves to cut perimeter 1 command to raise tool 1 command to move spindle out of the sway The program calculated points in polar coordinates 1/4-degree apart and converted the polar coordinates to cartesian on the fly. Run time was just under three minutes with a 1.5"/sec feed, and the curve was smooth. -- Morris Dovey DeSoto Solar DeSoto, Iowa USA http://www.iedu.com/DeSoto/ |

I'll try to get the manufacturer and part number and post here. Those I bought from Woodcraft were priced at $0.50/each. To make a local search easier, I think they were metric-sized. They consisted of a swaged tube with a captured ball-bearing and spring. In short, they are the cheapest kind of bullet catch imaginable - but they were exactly what I wanted for this application. :-) I'd suggest having the refrigerator compressor removed by a pro who has the equipment to capture the Freon coolant, and who can dispose of it properly. If you have an HVAC-capable friend, it's worth a six-pack to not abuse the planet more than it's already been. I suspect that my "extra" compressors weren't removed by pros, but that wasn't my choice. I understand that Freon is one of the causes of the polar "ozone holes" and not a good thing to let loose.

But I have a question regarding the "ball/button catch (valve)" you used - SOURCE, ITEM NUMBER and a request fot an instructable on converting my olf fridgerator into a vacuum pump - maybe a picture of yours. Not trying to be a smart ass here, seriously interested. Ace Hardware has a bullet catch. SKU # 998004145 Call local one and see if they have in stock. Found this on a search. Will post photo on ABPW. WW |

An audible hiss. similar to a pinhole in an air hose. Nothing offensive or loud. And BOY does that thing have holding power! Even on MDF. Now, stuff like unfinished oak with big grain paterns, I'm not so sure. But stuff like solid surface sticks like dog-snot on a screen door. |

Good, because the new Festool sanders use a vacuum and because the Rotex can be extremely aggressive I find that the wood that I sand needs to be clamped in place or it moves around. For years I have used the rubber "Router Pads" to hold the wood in place and to cushion the bottom side but they are no longer suitably effective. I was looking at the Festool clamps that clamp from the side edge but they are basically $90 for 2. I think this clamp that you have will fill the ticket well and will clamp and release more quickly. I'll probably have several supports blocks of similar size to help support larger panels. Did you buy the screw down version or the one that uses vacuum to also hold the clamp to the work surface. I am leaning to the latter. |

Did you buy the screw down version or the one that *uses vacuum to also hold the clamp to the work surface. *I am leaning to the latter. I am machining the entire table surface (4 x 8) with a flat bottomed bit and adhering a sheet of glossy white GP laminate onto it. The 'test puck' really, really sticks well to shiny stuff... MDF sticks as well, but nothing like the glossy surface. Therefore, the two-sided pucks is what I'm going with..either LV's or shop-built Morristech ones. The shop-built ones would work off a pump, the ready-made LV's are up and running the second you take them out of the box. For a 'holder' for sanding small pieces, the screw-down version would be my choice as you'd only need to keep one surface clean as opposed to two. I'll take a few pics when I do some trials at the shop today. Being a happy Rotexer myself, that would certainly fit the bill for you as well. I am also building a shooting board-type saw fence which will stick to my work rather than using clamps. |
