Here is a list of all the postings Nick Hulme has made in our forums. Click on a thread name to jump to the thread.
|Thread: Mill X axis|
You can buy a variable frequency pulse generator and use it as the input for a stepper driver, Arduino is definitely complicating the job unnecessarily.
|Thread: Limitation of a milling machine with low spindle RPM.|
That's still a low spindle speed, I have an Emco FB2 head which I run at up to 4000rpm and don't consider that as a particularly high speed.
|Thread: Material storage fpr Lathe/other machines|
I have Spur Shelving above head height for long lengths and a 900x600x1800mm 1000kg per shelf rack system with mesh shelves for shorter lengths.
|Thread: How to machine Acetal|
I use polished the TC tooling specified for Aluminium when machining plastic, it works very well.
|Thread: New vice, good choice?|
A vice of this form was the first which allowed me to machine work square.
I tried many cheaper models first, it would have saved me money to buy a more expensive vice first! :D
|Thread: DraftSight no longer free|
Crikey, a disappointment for cheapskates everywhere! :D
|Thread: Is CAD for Me?|
I started using CAD/CAM at 50, get stuck in, if you have the drive to do it you will succeed!
|Thread: Hexagonal Socket Drive|
That will be because a hex is smaller than a square then? :D
|Thread: Coolant Flow Rates|
The provision of cooling and the removal of chips to prevent re-cutting is the same principle on manual or CNC, especially in the absence of a full enclosure.
|Thread: mark 1 1/2 student with an inverter|
A friend and I re-wired his Harrison M300 for a VFD, we used all the standard switches re-wired to handle 24V control signals for the VFD so it now works exactly as it did with a 3-phase supply but with the addition of a speed control potentiometer.
|Thread: Another Workshop lighting problem|
I had double fluorescent tubes fittings throughout my garage and singles in my workshop, the LED replacement tubes give better working light than the fluorescents ever did.
|Thread: Stepper rating for Triac upgrade?|
|Thread: Denford Triac - Remove Easy Change Holder?|
It's a shame it wasn't a useful native taper
|Thread: Just for the Record|
I have the Record powered milling column for one of those but no mounting bracket, I used to use it as a cross slide milling attachment on my Myford, it's well made.
|Thread: Use a router for a mortice lock|
Even with clamped wood support plates the door fitters said drilling can split the surface veneer of engineered timber doors, regardless of whether spiral or spade wood bits are used, I suggested all this as I have that equipment too
To achieve a period look I routed the apertures for mortise locks (Key centre 3" from edge) and latches (handle centre 6" from edge) for 7 internal doors with a router.

|Thread: Feeds and Speeds! 0.4mm milling cutters...|
Cutter geometry is required for calculation, if it's 2mm flute length on a 1/8 shank that may not be wide of the mark, it's always a plan to start with 50% of the suggested feed rate as all guides will assume that everything about your machine is ideal for the job.
|Thread: Early metal lathes|
Done that, it's a 1950s long bed with 30.5mm through capacity headstock and roller bearings :D
|Thread: Self starting small steam engines|
There are single direction bearings which lock when driving, but turn freely when driven, commonly used for auto-rotate systems in RC helicopters.
|Thread: ARC Euro Trade Promo Code|
