CNC-2116 - Up and running, sort of (2015-03-21)

Delrin will last MUCH longer than HDPE and won't be any harder to form.
A water cooled spindle would be nice as they are a lot quieter than the air cooled ones but they are too hard too get in my power range ~9HP

Another small step done today. I drilled more holes to attach the back and front panels to the bottom plate of the base of the machine. I didn't have enough bolts for all the holes, however it's quite sturdy even with four bolts and the top panel missing. The bolts are not countersunk because this is the underside of the machine.
I can't wait to complete the base of this thing, I'd like to have at least one axis completed before the end of the month!
The six panels, seen on top of the reversed base, will go underneath the top panel of the base to reinforce it from back to front. There is 10 panels in the base of the machine and a total of around about 18~20 panels for the whole machine. So once the base is complete, the machine will be about 50% complete. Or only 33% complete if we go with the three axis needed, but from what I have read the base is usually the longest part to build.
And yes, that is a skate bearing you see in the front. Two bearings and four nuts will hold a 5/16"-18TPI threaded rod in place.

A shop vac is a very crucial part of a CNC machine, because of all the dust made while cutting.
So, imagine my surprise when last wednesday (my birthday), I got this little thing. Thanks Daniel!
This Shop Vac may be small, but boy is it loud! But it's also very strong, just like a regular-sized one!
Now all I have to do is built a little dust cyclone to go with it!
The name seems vaguely familiar for some reason... What's even funnier is that the colors are the same. ;D
edit: it doesn't matter if the capacity of the Shop-Vac itself is small, because the dust will be collected by the... eh... dust collector. ;D

I got that same mini vac for a wedding present. It's great. I can hook it up to my router table and really keep the dust down, love it for sucking up debris when doing engine work as well.

Does anyone know where to buy a Black and Decker RTX in Canada for a reasonable price? I really don't think my machine will be able to support the weight of the Hitachi M12VC and the Dremel is just a bit underpowered. I mean, it would work but I'll only be able to cut about 1/32" deep at a time. To cut a 5/8" thick panel would take 20 passes. It's still better than cutting by hand for complex shapes, but that's quite slow.
The RTX has almost twice the amps of the Dremel so I guess it would be a good compromise.
The problem is, the RTX is listed at 30~35$USD on USA websites (Target, Wal-Mart, Amazon) but I've only seen it on Amazon.ca for 52~70$. :dunno
