They can be cut, although since they are hardened, you will need to use an abrisive disc cut-off saw or angle grinder.
And here's "me old man" cutting up some continuously supported bearing shaft...

Tony, I don't think it is just about accuracy, but V-carving is beautiful too. It allows the shadows to show through and creates a wonderful piece that would be otherwise impossible with standard...

So what's in the box then?

Right then guys, since everyone is happy, mind the doors please :)

Sorry guys, can we keep this on topic please. Not really fair to cowanrg to crash his RFQ ;)

Sorry John, I have been putting off reading this due to the time required to take it all in! Had time today though, just got through it all from page1 and WOW. Your work is always top notch, and I am...

I'm there now!

Link no worky :(

What about micro-drop lube? No mess, just a nice smell!

Well I have the tapers made, and they work perfectly. Still got problems though, the new stepper was fitted today, and is still not powerful enough :( I am seriously considering using a worm gear...

Click on config at the top ok, then click on ports and pins.
There is a tab which says "motor outputs". In there, you will find the heading which says "Dir Low active". Changing the sign from an X...

Eric, read my first post - you can reverse the direction of the motor by using config -> motor tuning -> motor outputs and changing the little x in "direction active low" to a tick. Then once it is...

Hang on a minute, when a z move is commanded in the negative, the head should move down to the table. I a sure you know this, just be careful when you are messing with the settings, and make sure...

Home can be anywhere you like, ususally it will be minus, but use whatever works best for you. Mach is fully configurable.

You can reverse the direction ofthe axis by changing the "direction active low" tick box within config -> motor tuning -> motor outputs.
If you go into config -> home/limits then you can change the...

Swede has done a very nice diagram over here - http://www.5bears.com/cnc06.htm

I ahve not looked at the DXF, so excuse me if it is already covered.....If you machined a keyway the length of the spindle, then the spindle would be free to slide inside the driving pulley (dc motor...

Anytime buddy, Southampton is just a stones throw away!

Can't beat old lathes! Looking great Stevie, keep it up :)

Where can I find more info on this cnc-portal milling machine? I have plenty of experience with TC pro, but dont know what the miller is.

:wee: I will get onto it!

Thanks Jon, I just made it "this way" so I could find the centres using an end mill in the chuck. I see what you mean though, I guess I was just being lazy ;) Another pointer would be to cut the...

Right guys, time to ask for your help!

As you can see, I am using a piece of 1/4" CRS which is tapped to receive 3x 1/4" hex bolts to hold the tools in place. The problem is that I cannot work out...

Well, almost there! I have the boring-bar holders made, and drilled them on the lathe. Still need to drill and tap for some securing bolts though, oh yeah, and chop off my bars so they don't hit the...

Well I managed most of the wiring over the weekend, but it turns out my step-motor driver was garbage. I have just ordered a replacement which should deliver full torque to the turret.

Cut the...

Yeah, I make RC car alloy wheels. Generally, I use 2 or 3 tools per program so the tool change is a PITA. This will certainly alow me to get more adventurous with my designs.

Hoorah, finally I have some time to complete the turret.

I picked up a 6" x 2" disc of chrome-molly (EN24T) steel for the toolholder. The disc was bored at the rear to fit tightly over the brass...

That is DAMN good work Dave! Great to see people like you willing to take the time, not only to look into these dodgy dealings, but to let us all know about them too.

Cutting at 1 IPM at 0.1" deep would not be the best solution. Use an endmill first to rough out the shape, then finnish with the v-bit at a far faster speed.

No probs jc, that iswhat we are here for!

Gerry, yep, there is an R12 choice, my bad!
