Then it's time you treated 'her' to a decent MARBLE rolling pin - there isn't a better one !!

Not strictly true. Though it could be used as such by fitting an appropriate cutter. A Trepanning tool would have a flat cutting edge rather than a 'point' (oriented either left or right depending upon it intended use as a hole or washer cutter). To 'Trepan' is to take a thin ring of material...

As with all equipment, it is a 'proper' machine - within its design limitations (and the ability of the operator). It is certainly capable of producing small components in Steel, Brass, Alum, Bronze etc. particularly clock parts, which many users do when they can't warrant the purchace of a...

To some extent that will depend upon how you use it. You're not going to be able to take a 10mm wide cut from a 20mm dia. 316 Stainless bar ! but then, I can't do that on my Myford S7 either :unsure: - you will be able to take 0.5mm or so off EN1a. There are so many varieties of 'Steel' that...

Nothing like an 'End Mill' - did you post without reading @MorrisWoodman12 's post ? As he said, it's a Centre Drill - the perfect tool for the job. . . . and a hole-saw would not give better results - in the job for which this tool was designed - ie. primarilly cutting large holes in...

As is often (Always??) the case, 2 minutes spent drawing the problem provides all the answers - - - I'm sure I don't need to explain further.

Specifically since it is thought that there is water ICE there which can be used to sustain human life - once it has been melted by application of some energy of course.

Oddly enough, I have one that could be available for sale :unsure:

As is so often said but seldom considered relevant, knowing your machine (whatever it is) is the most important aspect in any workshop. I know my machines and often stretch them to their limits in both directions - sometimes well beyond the manufacturers claims :unsure: - In the past I...

I initially had that same error in my thinking - - I now suspect that the 25mm is the 'style' thickness.

Hmmm . . . I did wonder why you needed a 25mm deep slot :D In my case it was a totally different job - a 50mm deep 'pocket'.

This is a link to the one I bought 4mm Shank 2 Flute Tungsten Steel Mill Spiral Cutter CNC Router Bits Carving Tool | eBay which is a 4mm with 4mm shank. Another for a 6mm x 28mm with a 6mm shank - from a UK supplier - Solid Carbide 2 Flute Spiral Router Bit End Mill Up Cut - PVC Acrylic Hard...

Have you considered using a 4 or 5mm Router Bit and take two (or three) cuts to achieve whatever slot width is required? I'm sure that the 5.5mm will not be totally consistant across the whole board. I need a 'reach' of 50mm for a current project and was able to find a 4mm x 80mm bit with 52mm...

Very strange how life brings subjects to the fore. I don't think I've used my ER Collets on my lathe this year but yesterday it became abundantly clear that I couldn't complete my latest project without. It so happens that I need to use the 'Gap' in the bed since the work I have to turn won't...

It's impossible to be absolutely precise since I don't know the dimensions of your particular bearing but in principle, of course the 'cage' has to rotate at a different rate to the cups. Assuming a 60mm OD-35mm ID bearing - and a taper roller 8mm at the large end and 12mm long - - the outer...

Ah - as should I (have been more precise!) - I made my own ER Chuck (I did buy the nut - I'm not totally mad!) which fits the spindle thread on my lathe (and fits the register dia.) so I don't have the restriction of being driven by a MT shank - which of course does restrict the length of a...

True - BUT - this feature actually limits the choice of material that can be safely & securely held. The advantage of ER type is that they can securely hold a range of diameters, mostly -1mm from nominal but below 4mm it's -½mm I'm not sure about the imperial sizes - I only have 2, 1/8" & ¼"...

If your headstock spindle is hollow then you can very easily make a draw-bar. Even if you start with a length of threaded bar and add a washer and nut. Better to make a suitable bush that fits the rear end of the shaft though since that will keep the bar centred. The MT2 ER Chuck will have...

??? how would you use an ER32 collet systen to turn between centres ? 'Between Centres' means exactly that - a 'Centre' in the headstock and another in the tailstock, with the component clamped in a carrier powered by a drive pin, the component having previously had a 'centre' drilled in each...

That does depend upon the operator - to some extent. I seldom use a 4 jaw chuck though they do have their place. I very rarely use the hard jaws that are generally used with 3 jaw 'seft centering' chucks, much preferring 'Soft' jaws which I machine at least each time I have to re-mount the...
