Perpetual Motion is a What?

"On our planet we can only try to get as close as possible to this phenomenon"

Perpetual Motion is not a Phenomenon, in this reality, with the Prevailing laws of...

You can knock most of the point off a spiral flute tap without affecting it's function. In this way you can get close enough for finishing off with a custom trimmed bottom tap with reduced lead-in to...

Oh that's pretty neat! I can add it to the long list of projects lol...

Enough of this manual lathe nonsense, today I fired up the CNC at last and made the top plate for the new Z-axis.

First...

Discard the last 20% of water and the issue is slight but just using a higher pressure pump will give you much better efficiencies even without recirculation.

Water with a TDS of 0 is very...

That'll be an air stone ;-)

Made me smile as it reminded me of a minibus driver I had last week, who took it upon himself to act tour guide.
"This used to be the mine weighbridge, where they used...

A bit of lateral thinking... You need a FORGE!

Re. linear rail lubrication.

Have a read at this thread; http://www.mycncuk.com/threads/4862-Profiled-rails-Installation-guidelines-and-manufacturer-comparison-chart

The right stuff at a good...

There is proper guideway lube from manufacturers like mobil, which I think would be a massive waste and too expensive for the sake of cheap chinese copy rails on a little router.

The de facto is...

Just got mine working I agree 100% for the price an essential purchase, it's also nice having the coordinates on the screen. Very responsive as wellhad read it could be slow to respond but real time...

I bought this one last Sunday

It was shipped by royal mail yesterday 48 hour...

I've been using the wireless version of the HB04 for a while and still on original set of batteries. It's actually the WHB04B, a slightly later version, which has two knobs (apart from the big...

I have one of those xhc ones. mines wired aswell due to lag over wireless ones. all works great on it, hardly have to use thekeybourd or mouse anymore because it has so many functions on it.

Great way to firm up the 6040 bed. . . . . . .Replace virtually the entire bed with an enormous vice!

I think it looks good. :smile:

Is the air flow enough to blow the chips well out the way?
Provided it's keeping chips well away from the cutter, then your setup should be fine. Even if you have to give an extra blast...

It's offset so you can get the collet in/out easily.
If it wasn't offset, you'd not be able to get the collet in/out easily, or you risk the collet popping out the nut when trying to remove the...

Pretty much. I just ran an earth cable from a bolt at the back of the frame to the box and earthed everything at that point. It was sticking a CY cable on the spindle that solved my problems.

Typical stepper is 200 steps per revolution. You have 5mm screws, so you move 0.025 per step (5/200).

Microstepping doesn’t really count, so the fact you have eg 320 per unit (can’t remember...

Well you can anodise using phosphoric, but all these guides are based around the use of sulphuric acid. I don't really know much about phosphoric acid anodising but I certainly wouldn't assume the...

Given they are fairly small parts with tight nooks and crannies I'm not convinced you'll be happy with anything other than sand blasting.

You could try tumbling in a finer abrasive material like...

Quite big!

From the description-


I'm about to head to the workshop so can get some accurate measurements, but it's about 18" tall, and is currently sat on my 12x18" granite surface plate....

I'm afraid I don't use the same motion controller as you, nor do I use Mach3 anymore... but it should be fairly straight forwards.

Hook it up to the same point that the normal probe goes to, but...

that's probably the way i'd do it personally yeah

With something like that, I'd be making sure they were well earthed, and powered via a good RCD.

Have you had a look at any of the youtube videos for ideas?
I've got these saved in my watch later...

Nick, that is similar to what I've already got, albeit cleaned up a bit, and the equipment sales bits removed.

I don't think Ron ever sold the guide digitally, as any reference I did find, was to...

m-c, is this the Ron Newman guide that refer to? www.uponone.com/howtos/1.pdf

Nick.

Edit:- This looks like the information off his website, rather than the guide.
