One easy method of labeling things like this is simply to print your design on paper, then put some perspex on top of it and secure the perspex down somehow (rivets/screws/whatever). Makes it quite...

That message was automated spam.

Back to the OP - I think something is wrong if you're getting chatter and a poor finish with a light cut.

I have the same mill and I can take a reasonable cut...

Can LinuxCNC do rigid tapping with a spindle motor that isn't a stepper or a servo, ie with just a VFD and rotary encoder?

Forget the circular interpolation, just use a boring head the whole way.

Remember to check the alignment of the bore to the spindle AFTER you lock the table axis, and remember to lock the Z-slide...

I get a nicer finish than that on my mill which is a manual RF45 clone.

Is the cutter definitely good? Try another one?

There's definitely nothing wrong with the machine itself, ie, you don't...

There is no height adjustment on the tailstock. If it's wrong (it's probably high) you need to take it apart and scrape/grind/mill the underside of the top part.

I believe the procedure is documented in a video, or article, by Tormach. Search for it.

The bottom line though is that you measure your backlash using a dial indicator and some small CNC...

Hi folks,

I have a 10x20 Denford Viceroy lathe, it's about 350kg, and I've just started drawing my plans to convert it to CNC.

It didn't come with a leadscrew, and I'm wondering what diameter...

Hi folks,

Well thanks for you advice. I went ahead and bought the lathe.

On close inspection I believe I will mount the bearing blocks primarily via the Vee on the bed. The bed is nice and...

Hi folks,

Had my eye out for a while for a Denford Viceroy "plain" (ie non-screwcutting) lathe, because of the lack of screwcutting you can get a real nice quality lathe for cheap on the used...

Key it and then fill it with epoxy granite?

Hi guys,

Not trying to hijack the thread here but something caught my eye. Regarding using a 460v motor at 230v. My mill came with a 3 phase motor which had 460v and 220v mentioned on the...

It's not normally that difficult, but don't be tempted to lube up the spindle else your tools will never stay in place. Make sure it's clean.

Do lube the drawbar threads though else the torque you...

Hi Hoss,

Are you trying to design the PDB to still permit quill travel?

Hi folks,

Just a quick update on the collet fitment issue.

The problem was the R8 collet alignment pins. On my mill these are essentially just two set screws which have been screwed through the...

Simon,

I have a spare set of plastic ones if you'd like them, just let me know.

I fitted metal ones and had a plastic set in reserve, doubt I'll need em now!

Metal gears don't seem any...

Hi folks,

Just got my first mill delivered today, a ZX45 type, got it in place with an engine crane but the gearbox was seized! Also my collets don't fit...

I ordered it in 3 phase as I wanted...

Cheers guys.

Hi folks,

Got a new mill arriving on Monday and I'm tacking up a steel frame for it.

I wonder if someone who owns an RF45 type mill could do me a real quick favour and measure the distance in...

I'm going to guess that you would need a few depressions of the foot pedal to achieve the stroke you'd require, unless you fiddle with the bores in which case you may end up not having enough...

Hoss,

Weird, I was literally sitting imagining how I would make a rectangular air cylinder for this purpose last night. How are you going to seal the piston to the bore? I concluded that using...

If the hole is round but just perfectly undersized, have you not just got the wrong tool width set (or the tool is undersized due to being reground at some point)?

Hoss - for what it's worth there is a UK supplier selling the same mill with an R8 option. See AMADEAL Ltd.. I'm sure I've seen a video of a continental European chap with an Optimum one sporting an...

Do you perchance have this sort of problem:

http://img85.imageshack.us/img85/3884/gibl.jpg

I've seen this on all the gibs on my mini lathe and the result was a single 'streak' as a wear mark...

I'm far from an expert but I suspect the problem you have, based on my experience with repairing mini lathe gibs and what I've read from those who made their own, is that after machining your gib...

Wisdom :cheers: Will probably do just that.

Cheers for all the advice folks, really appreciate it.

Been watching eBay, Gumtree and other such sites for months. Loads of big machines (500kg+) and the odd old Bridgeport for £2-£3k, but nothing really suitable or on budget.

Might just bite the...

Yeah I was thinking about having some screws (threaded studs with a handle on top) that screw down and jack the stand off the floor, thereby unloading the BTUs, and allowing levelling. Moving the...

Double post.

Hoss, that's an interesting point, for the price and hastle of delivery I could think about spending a day with a hire van having a bit of a roadtrip.

Getting the mill out of the van at my house...
