|Thread: Help with finding or making router duplicator|
I'm not too sure about the choice of material for the duplicate gun stock.
|Thread: Co2 emissions.. Steam or diesel best?|
Particularly those most verciferous.
|Thread: Removing superglue from an oak table|
Nothing new there!
|Thread: Stanley Blade Lathe Finishing Tool|
Interesting use of the bandsaw as a power-file towards the end of the video when he was making the knight.
|Thread: 042 Locomotive plans|
Please can we use the correct Whyte notation and call it an 0-4-2 locomotive? Christmas rant over.

|Thread: Slight repair required|
If iron, without a specialist muffle to do a pre-weld preheat and (more importantly) post-weld normalise I wouldn't even think about welding. Brazing would be far safer thus minimising the likelihood of producing brittle carbides each side of the weld.
Ali is a completely different ball o' wax.

|Thread: MR16 LED Spot lights|
I'm a little unsure why a number of us are getting all excited about varying voltages with varying lamp-holders. Similar pattern incandescent lamps and their LED replacements have been available for years in both 24v and 230v with B27 and GU9 bases
Additionally both 24v and 110v lamps are available with E27 bases of the same pattern
|Thread: magnetic motor|
Do I smell Snake Oil?
|Thread: Myford Super 7b lead screw end float|
For intellectual completeness could you provide a bearing part No?
|Thread: Keyway Broaching|
Can you get access to a shaper? They are one of those much undervalued machines well suited to such tasks.
|Thread: Myford Super 7 Apron removal|
I don't have the gearbox model but I can assure you the lead-screw needs to be removed to the tailstock end before the PXF apron can be removed.
|Thread: a good quality milling vise for sale|
That said, the jaws show very few, if any, dings.
|Thread: Plumbing question|
Those with the slightest knowledge of electricity will recall water flow being analogous to electrical flow. Now apply Ohm's Law to your pipework.
|Thread: Tool steel - Beginners guide ?|
Wouldn't it be possible to turn down the shank of the one suggested earlier **LINK** ?
|Thread: Meddings M10 VFD?|
I completely endorse the comments made above.
Additionally I can say I had little difficulty finding the "star" point on my ancient "415v" 3/4 HP Brooks motor when I converted it for VFD use. I think the only motors that may prove difficult are those when the windings have been potted in epoxy.
The only real word of caution is not to rotate the motor at more than its centrifugal limit. Motors designed for 50Hz can do bad things at 400Hz.
|Thread: Suggestions to pack round DC motor so bracket holds|
Would it be possible to wind a number of layers of self-amalgamating rubber tape around the motor body making sure you don't obstruct any ventilation holes?

|Thread: Electronic Lead Screw Project|
Between my other large list of other jobs I'm in the process of fitting one to my S7.
I'm trying very hard to squeeze the stepper motor into the change gear casing at the LH end of the machine.
|Thread: Diesel horn|
Try an Adafruit Audio FX module.
|Thread: Machining an S50 casting|
I was taught many years ago, when making patterns, to always put ample machining allowance on a casting. It would seem whoever made the pattern(s) for this was absent from that lesson.
|Thread: Positioning bushes for welding|
Weld in pieces of rod that have only been centre drilled. Weld into the plate getting them as square as possible the drill through with a mag drill.
