Sorry for the late response,
You can get the steel rail here http://www.grainger.com/product/PBC-Lin ... 1?$smthumb$ and the correct model ball screw can be bought at eBay or Aliexpress http://www.ebay.com/itm/1pcs-antibackla ... 19d54f6cb3
The HD plates are still undergoing testing but the SD plate designs have been submitted to our manufacturer for quotation and eventual production that will begin next month. We'll be able to release the DXF files for both models in the June to July time frame. We'd like to have a dedicated location on our website to download drawings, DXF files, models, etc so it is going to take a little bit of time to get everything made and setup. Thanks for the offer in making a Solidworks model, we're currently being taken care of in that department but it's good to know you have that capability. We may ask for your help in future projects.
The 3kw spindle is holding up really well thus far. It provides plenty of power and we've had no problems with its operation. It's quite smooth and fairly quiet and since it has a lot of torque you can drill or cut parts as low as 3,000 RPM (though we usually operate in the 12,000 to 18,000 RPM range) Granted it is a budget spindle so we anticipate about 3000 hours of use before the bearings need to be replaced, but considering it's price point you can just buy a new one. Though if you want a real high quality spindle that last a lot longer between repairs or replacements you'll have to pay a lot more. So you either pay a lot up front and go many years without problems, or you pay a fraction up front and have to repay that amount every 18-30 months, depending how frequently it's running and what you're cutting.
I haven't quite decided on a spindle yet, I kind of figured sticking with the cheaper spindle to start, get some money flowing, and a good quality spindle would be first on the list. Then again I have a Porter Cable sitting on the shelf that I could mount and start with engraving signs - I run a sign/decal business so it's one of the first things I'd start with but have many ideas to expand into including thicker plastics and aluminum - why I would want something in the 2.2-3kw range
Nice to know about the model, I'll be patiently waiting
Rails are cheaper at Zoro, unfortunately I didn't see your post until I ordered. Couple bucks cheaper on the rails and $5 to ship - Grainger charged $10 to ship
