I have done a couple of searches on this already, and I didn't find what I needed. Hopefully, this hasn't been hashed to death already.

Back when I built my bench CNC mill, the spindle choice was...

if Dave is really asking ~$13,000 for that machine in the video, honestly I'm not sure how he is managing it. Is he personally building these 1-0ff when someone wants one? It's obviously a very...

It boils down to the bearings.

To simplify, picture a BIG ball bearing with a FOUR INCH inner diameter race... you'll need that much just to support even a minimal spindle. Now you'll need balls,...

Years ago, finding a decent spindle for a home-brew machine was a genuine hassle. On one end of the spectrum, there were fine quality (but very light) ER and MT spindles for machines like the TAIG...

You'll like the system, Rob. It is perfect for PC board routing. I can picture some very east to set up clamps and such for the PC boards that take full advantage of the T-slots. And since most...

cj, thanks for the suggestions, but it's hard to ignore the effort I've place in Rhino. I do like it, and there's a lot of power I need to tap. I'm definitely the limiting factor in all this.

It...

That is awesome... It's got to be tough to get nice, smooth running at such an RPM!

Great job!

Thanks guys, good to be back in the game!

It looks like at least one upgrade, then, and that won't be too bad. It's great having people who use CAD/CAM software give unbiased views, because (as...

Hello Bill, thanks - I'm getting some replies and hopefully will get this thing back in business with the correct board, but it's good to know there are alternatives. :wave:

:D After our chat, I am motivated to get my ancient web sit updated...

No word from FC yet, but it is early. Like many problems, if you throw enough $$ at it, this one will be fixable too.

In...

Yeah tough lesson learned. I don't think of myself as a dummy with electronics, but I was in this case.

FC has been very good to me in the support area. I'll go through my docs and see if there...

Hi Nick, I'm the 5 Bears guy. I've been humbled by the number of people who followed the site over the years, and I hope to get it going once more.

The design and concept isn't mine, it's been...

Thanks, Al. I received an immediate email response from FC on a Saturday, which was impressive. They are going to look for a board on Monday. If that fails, I will begin looking at a bit of...

I'm bumming - Yesterday, I was cleaning and checking my FC 20 amp servo box, an older one with the silver case, and thought, "I'm going to add an external emergency stop switch." So I added a...

Does anyone know if this guy has a web site? The pictures show an outstanding level of craftsmanship. I'd love to see some work-in-progress shots with context!

I would not use these for a table unless you can accept a flatness that is not perfect. I don't know the tolerances, but if you clamped these together to form a table, I'm guessing it'd have...

TY for the excellent info. I have a lot of research to do, and quite a bit of software in need of upgrading... the cost for upgrading all of my CAD/CAM stuff right now is looking like $2k - ouch!

Is this a new sub-forum? Maybe I missed it before.

I agree that the Bosch "heavy" sections are superb. It's hard to describe it until you actually use these things, but the full-length T-slots...

Kind of a late reply, but it might help someone...

The usual wire is stiff and crappy hookup wire, but a better alternative exists... look for some rubber-sheathed test probe cable, the same sort...

Some truly magnificent work here. Contrary to popular belief, smaller does not equal easier with IC, as getting good compression is tough, and the fuel/air mix doesn't scale properly.

I've built...

Hi Harry - here's what I'd recommend with your shop crane - I don't know if you have any, but look for nylon strapping in the appropriate load rating and skip any chains, unless you want a chain on...

Thanks guys. I am leaning towards *not* upgrading. These extreme upgrade costs make me a bit angry. How did it reach a point where the upgrade(s) now cost more than my V4.0 PRO did when I bought...

Hi guys - First posting in many years! I was very active a few years back, then other things got in the way... long story.

I am dusting off all my CNC yumminess, which consists of my homemade...

Guys, don't overcomplicate miniature engine construction! Unless you are one of the rare builders whose goal is to create a race engine, or you want to pursue theoretical limits, remember what your...

Yup, that incredible work graced the cover of Strictly IC magazine. I hope I didn't give the impression that the idea was mine, it is a pure rip-off of this guy's work, with the primary change being...

Beautiful work!! :)

These guys are photo wizards. All I'll add is that for web posting, I take my pictures at a 640 X 480 resolution and end up cropping them anyhow. LIGHTING is the key, along with a decent lense and...

My FUTURE shop. My current shop is as packed as everyone elses... I have to climb over stuff to get at my band saw. My air compressor is 6" from my vertical mill.

As soon as the current owners...

Truly beautiful wildlife photos, kudos...

Hmm lots of shooters here. I enjoy NFA firearms, but that's gotten very expensive lately. Gunsmithing is a natural extension of machine tools.
