Isn't MasterCam $10k or so? Don't know many people that would spend $10k to run a $2k bench top mill.. Or are we talking bootleg MasterCam copies? We use SolidCam at work for 2.5D stuff (because...

Great to hear!

The "Main Body" is the first sketch / extrusion of your part file. (Normally this would be called something else, I just automatically rename it "Main Body"..) So you make a sketch in a part file,...

I drill holes all the time in aluminum with my Taig milling spindle, at 6,700(?) RPM and more often 10,000RPM. I typically peck drill at .02" to .05" depending on drill diameter, at 15-30 ipm. (G83...

I would suggest only unscrewing the drawbar a few turns before whacking it personally.. Otherwise when the collet / chuck lets go it can drop out and be damaged, also the end of the drawbar (and /...

Thanks for the quotes guys! I'll try and respond to all the emails.. I got quite a range of prices, from $0.55 each to around $2.50 each.. I'm guessing the differences are due to $ / hr machine...

Hi,

Was going to do these myself by rough-cutting 5/8" rod on the bandsaw then cleaning them up in my Taig lathe, but I figured someone using a solid CNC lathe with a good parting tool and bar...

Never saw anything more about the Avenger spindle online, though I haven't looked in a while.. As usual the build of the machine got delayed due to work, funds, and my wedding.. Hoping to get time...

I don't know if it would make a difference or not, just throwing out a guess. :) I've never used a V bit for circuit boards, I've always used conventional (tiny) endmills.. Less chance of...

Any chance one side was climb milling and the other conventional?

DOH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Wow. (runs and hides)

:)

Honestly never used "Hide" in a part file before, so had no idea to even look there. I might have...

Never seen this happen before, and no idea how it happened or how to fix it.. Lots of Googling and I haven't found anything so far... Basically, I have a simple part that a microswitch mounts...

When I bought my Taig mill on eBay 5 years ago, it came with a 4th stepper attached to a 1/4" thick aluminum angle bracket, with a mini 4-jaw self-centering chuck mounted to the motor shaft. The...

Interesting.... Do you know what the lead is on the screw? And the diameter? I run my .2" lead ballscrews at 2000RPM to get 400IPM rapids, no idea how to calculate the force that would be acting...

I'm using ballscrews and thought "hmm, why not just rotate the ballnut on the long axis?"... Totally didn't occur to me that centrifugal force would come into play! Guess that's a good reason...

True on the shipping.. I guess we had to see that one coming! :) Buy-it-now for $.01, $34.00 shipping, what a deal!

Sometimes when I "watch" an item, it's because I have one similar to sell and I just want to see what the going rate is.. I too usually get more watchers than bids on stuff that I sell.. What...

There are quite a few websites dedicated to the microstepping discussion.. I have some Parker Compumotor stepper drives that will let you select down to 256-microsteps. Is that at all possible...

A lot of neat stuff there! I like the way the bellows are done, I might have to borrow the idea. :) If the stepper drivers turn out to be step/direction driven, they may work as-is with Mach3...

That's quite the belt drive! I was going to say it was the same as the ServoBelt thing, but realized there's no lower belt to mesh with the top one. Just a "normal" belt drive, with the belt...

Nice! I think I used the SHCS method because I wanted to be able to fully remove the screws if necessary, and for some reason I like to practically stand on my allen wrench when I tighten my screws...

You mean the holes in the side for screws that go into the tapped ends? No pictures unfortunately..

I usually just set the 8020 piece on edge in the vice on the mill, drill a 1/4" hole through,...

I use that method all the time building 8020 frames at work.. It's way stronger than angle brackets, assuming your cut end is perfectly 90*. Plus you can't see the fasteners, for a cleaner...

Do you mean Misumi? ( MISUMI, the catalog company of Machine Components eCatalog ) Or Mitsumi? ( Welcome to Mitsumi USA & Europe Website! ) All I can find at Mitsumi are electronics products.. ...

8020 is great stuff (I use it all the time, and am currently building a fixed gantry CNC with it), but if you're shooting for .001" (cutting accuracy, not tool location repeatability anyway) you'll...

Those Thomson slides are what I've used on my modified Taig mill for years now. Great all-in-one units, but I got them for "cheap" on eBay and from someone on the forum. In fact I have (2) 42"...

Wow, good stuff! :) I thought the part numbers were odd.. Probably like the visions systems the place I work makes; base part is the same but customer can order different firmware versions, which...

I used that initially, but it doesn't have the little things like undercuts, internal dimensions of the taper area, key slots, and the dimension of the big end measured 39.5mm instead of 40mm.. Also...

I couldn't find a model of the Little Machine Shop 1407 spindle (this is the X2 R8 spindle, right?), so I drew one up.. Anyone care to check it out and see if I did anything horribly wrong? I...

LOL... I thought about using it for PCB's, but I too would rather just send them out to be made. ExpressPCB is cheap enough, and boards come back better than I could make in just a couple days. ...
