|Thread: Spiral Flute Tap?|
As you do not need to back them off to break the swarf you do not have the problem of swarf jamming the flutes and helping to break you normal hand taps, particularly taper taps! I rarely use hand taps now.
|Thread: Anyone know where I can get hold of 'Gauge Rods'|
Never seen a 0.001" guage block, not able to handle something that thin
|Thread: Repair required for Milling Knee|
I think I would have left it where it lay, in pieces and still having the £50.
|Thread: Die filers for beginners?|
Hemingway used to allow purchase of drawings ahead of main order and would allow credit of cost of drawings if kit ordered later. You could ask them.
|Thread: Just for fun what’s this stuck in my tyre?|
Pointy end just right for wedging in the tread gap, my guess deliberate.
|Thread: M4 x 0.75mm pitch CSk machine screws|
Yes is the answer, it all depends upon how many items you need.
|Thread: LED Dimming|
LED dimmers do not vary the voltage, they vary the period of time (ie part of mains waveform only) during which power is applied to the LED.
I neither have buzzing nor flicker with typical light switch dimmers.
|Thread: What coating/grease for long term tool storage|
Kiwi Bloke, please do not use "vaseline". (aka petroleum jelly)
I used to test vast quantities of it when used as an insulator in sealed EHT transformers, I can assure you it does absorb water if exposed to atmosphere.

|Thread: Kennedy Hacksaw bearing replacement|
You could of course "fill the gap" with a plain bearing of appropriate size?
You do not say what metal the tap is in.
|Thread: Part built Allchin 1.5 inch|
The screws were presumably there to hold parts during original silver soldering assembly. As such they merely held the flanges etc in place and take no real part in the boiler's integrity.

|Thread: Myford colours|
I bought "Myford Green" from Mason Paints of Derby and it was spot on BUT unfortunately they no longer exist.
Of course it may well not be a RAL colour? !!
As regards the DIY matching, I think what you end up with is the nearest in their own mix group colour
|Thread: Lathe Speed - What am I missing out on?|
If it rings like a bell, this shows you are exciting it at a resonance and a sure indication you need to change speed. The advantage of a VFD (variable speed) is that it may only take a small change to go off resonance and hence improve surface finish.
I would hope that your <1mm would be considerably less, perhaps 40x less (I work in thous from time to time.)
|Thread: Grid Frequency [mains electricity]|
Of course if you have a smart meter they could switch off any or all domestic loads and leave the trains running.
Politicians should engage brain before mouth, 80% renewable would require us all to generate our own and no Grid.
|Thread: Lathe - dead centre wont reach the workpiece|
It would seem that part of the thinking problem/solution is believing that the top slide must always be at 90 degrees to cross slide.
|Thread: Is your spindle bore large enough?|
My M300 has a 38mm bore and can swing an 11" 4 jaw BUT there are time when on small precision work and threading I prefer the Myford S7.
in the end it boils down to horses for courses and depends entirely on what you are making.
|Thread: Harrison M300 or M250 pulley/belts problem|
MC Mine is the later headstock wih the completely flat face where the gear selector controls are. I would hazard a guess that you may not need to worry about the roll pins but merely remove the M6 and draw off the double pulley using a simple puller.

MC Have now dragged my M300 handbook out from its resting place. Headstock parts breakdown clearly shows M6 x 20 bolt Part 33 screwed into end of shaft through "safety washer" part 31 and "washer retaining" part 32, pulley is keyed to shaft by a single woodruft key. So appears to be, M6 bolt out and pull pulley from shaft axially. No sign of any spirol pins
old mart. There are 2 belts in parallel which must be a reasonable match.
MC My M300 (late model with sloping front edge to tray) has much more clearance from the pulley (120mm dia) to the headstock than your photo appears to show, belt changing is easy and the pulley is fixed with two set screws and does not have a centre bolt. Not much help for you but it does show there are variants.
