|Thread: Sealing Brass?|
I believe you can get clear powder coating - that might be an option?
|Thread: Anyone know what these are called?|
I had one of these, given to me as a present by the in-laws, in the form of a fiendish jigsaw puzzle. Fearing I would never get it back together if I disassembled it, I think I passed it on to a friend. Or maybe it's in the back of a cupboard somewhere? It was in a box with a name on it, I'll try to find out what it was.
|Thread: Ambiguous words|
Speaking of the NPL, our favourite site lathes.co.uk refers to it as the National Physical Lavatory on this page

|Thread: Roolo Elf lathe|
A post for each of the speeds, Hopper?
I'd love to see a photo of this lathe, please, sounds intriguing.
|Thread: Boll-Aero 1.8cc Diesel|
My copy of "The Vintage Motorcyclist's Workshop" by "Radco" advises never to use silver steel for spindles, or any parts of the suspension e.g. in girder forks.
Now we know why.
|Thread: Electric bike fault|
If you have the equipment, I'd recommend testing the battery voltage when it's under load - I used a multimeter, and a 240 volt filament bulb. The battery voltage when charged should be around 48 volts. The LEDs and push button on the battery probably won't show anything useful.
My suggestion from your previous thread still stands, I'd take bets on the problem being inside the battery pack, and most likely the circuit protection board.

Edit - noted that you changed the battery, but the new one could easily have the same issue.

|Thread: Which Collet Chuck?|
Saw this video earlier today which shows how to make what would seem to be the best of both worlds regarding backplate vs Morse taper. Basically a threaded "nose" which takes the collet. Only hard part for me would seem to be machining the taper for the collet.
Quite fancy having a go at making one myself one day - it's on the list...

|Thread: Drilling holes in thin material|
Just been watching this video by Mark Presling where he shows an interesting trick for drilling thin sheet material. Can't wait to try it out!

|Thread: tumbler gear arbours on a myford|
The locknuts are fairly obvious if you look at the back of the assembly (on an ML7 at least), so if there aren't any, it may be that a differerent method was used on that particular machine. Seems unlikely though.
Swarf - I think Bricky needs to replace a stripped gear, there's another thread about it.
Edit - Hopper got there first

|Thread: Recommendations for a suitable Book binding glues|
I'm by no means an expert, but many years ago when I helped out in the school library repairing books, Copydex was the glue of choice.
|Thread: DOS (V6.3) Commands - Selecting file attributes for use with the DIR *.extn command|
dir *.con /od
Edit - if you type any DOS command with the /? switch, it lists all available options e.g. dir /?

|Thread: Domestic Chemistry|
Tried IPA, didn't work as well as expected.
|Thread: speed control pcb for Clarke CL300 lathe|
Servisol is good, but last time I had a dirty potentiometer I'd run out, so tried Ballistol instead. Worked a treat.
|Thread: What adhesive - that shrinks when it sets - do you recommend for melamine laminate sheets?|
+1 for ^^^^^
|Thread: April questions---for one day only.|
Apparently the customs papers for a chap importing hydraulic rams into Zimbabwe were maked "Livestock"
I think Colin is making the handles as well, so he can thread the ends to suit metric balls if needed.
|Thread: Tracy Tools Delivery|
Just another bit of praise for Tracy Tools - ordered a number of drill bits late yesterday afternoon (replacing the broken ones in my sets) and they arrived by Royal Mail before lunch today.
Just had a search on Ebay for "plastic ball handles" and there's quite a choice available.
|Thread: April questions---for one day only.|
Hang on a minute... these sort of questions sound a bit familiar
Nice one Steven.
