Re: Drilling with Shapeoko

I hear ya on weight. Big issue. One I am trying to solve on my new build by using even bigger gantry extrusions than most and a stiffer x-axis carriage. Right now, I can see the flex in my machine, namely the x-axis twisting generally the whole gantry when drilling in hard materials like aluminum. T...

Shapeoko Inspired New Machine Design

So, The machine in my signature is running great, but I'm in a never ending quest for more stiffness...until I end up with a HAAS VF9 sitting in my shop haha. Alas, my budget isn't there, and I enjoy designing routers (mills are another ball of wax). At this point I am going with the largest extrusi...

Re: Drilling with Shapeoko

Roger that RobCee. I think reducing spindle speed will be key. All I can say is the runout will be far far better than the craptastic drill presses I used today. My home press is far more accurate, and I think a good idea will be to use a center bit in the Shapeoko and then the drill press after to ...

Re: New, larger aluminium extrusion

Thanks for the details! It will be neat to see a machine built around the MegaRail! Let me know if you need a beta tester...

Re: money to spend but need help

I'm with Will on the openbuilds website. It has gotten worse, not better... The questions you need to ask: 1) What are you intending to machine? 2) What cut area do you actually need? 3) What additional accessories do you need? I think the Ox machine, available in Europe with 0.25" aluminum plates i...

Re: Pressure plates?

Just use a Gast vacuum pump, search rcgroups for a used one, they pop up occasionally. Super quiet, I ran one in my shop for years. Besides, milling thin sheets, especially in aluminum, is very loud anyway, louder than a shop-vac which makes the same amount of noise as a regular vacuum cleaner. Cert...

I think what you are really looking for is a vacuum hold down plate: http://www.microsystemsgeorgia.com/smar ... sitory.htm

Re: money to spend but need help

One of the limits to the Shapeoko 3 right now is the size-the extrusions aren't yet available in longer. If sign making is a business, I would highly recommend a CNCRouterParts machine, or possibly the Routakit HD. I'm building a new machine for semi-professional work, still belt driven, in-between ...

Re: Drilling with Shapeoko

Yep, I'm aware of the spindle speed issue. I'm quite sure the 1/4" hex shaft won't be GREAT, but I have the stock collet the Dewalt 611 came with to try. I might give it a whirl. I'm really not planning on doing a lot of holes. Maybe it makes more sense to mill them, but I don't think so. I think th...

Re: New, larger aluminium extrusion

Hardcoat anodizing may be more cost effective than adding more delrin v-wheels...the steel v-wheels from Inventables at $10 each aren't bad, but the steel rails from zoro/grianger etc. aren't exactly cheap and mounting is a pain. Just food for thought. Also, understood on your shop...are you plannin...
