|Thread: Retro fit heated window elements|
Looking at the instructions with the kit contents in your LINK I think you will require two more of the vertical strips if you are going to fit out to two windows. My guess is they make contact with only two of the three strips at each end.
I guess you should see if Holden will supply you with two extra vertical strips to let you use your spare element strip on a second window and then wire the two assemblies in series to avoid the chances of overheating.

|Thread: Hot Buildings and expansion.|
Pattern makers still have separate rulers with allowances to suit the metal being cast. Chesterman Rabone offer a set of 4, one standard and three to suit Iron, steel and brass. (aluminium alloy is generally the same as brass). Trouble is there are far fewer local foundries than in our forefather's days so you don't see many of them nowadays. You got to go East to find them today.
|Thread: Left handed lathe?|
As a lifelong cackhander I reckon the standard lathe was designed for us. Your body is naturally further away from the chuck and it's even better if the saddle wheel is to the right of the cross slide.

|Thread: HSS replacement tool tips.|
There are plenty of sources for TCMT 1603-04 but they are Tungsten Carbide not High Speed Steel. Are you sure about the HSS bit?

|Thread: An Odd Screw|
I think you've "nailed it" The top bit does look remarkably like a wood screw thread.

Trying to tidy up and checking the contents of long forgotten boxes of assorted screws I spotted half a dozen of these today.

|Thread: The cultural status of engineers in the UK|
The fight for recognition was lost when the English spelling adopted Engineer as opposed to Ingenieur. The continentals associate it with ingenuity whilst the English more often think of blue coated mechanics and the Americans drive locomotives. C'est la vie!
|Thread: Help milling an angle|
After reading your comment, I just cheated and went to Grotto's album, called "Brake", so I guess a 6" long plate with a 60º included angle along one edge to form the blade for a sheet metal bending tool.
The light really shone bright when you down load the whole set of vice brake drawings that Michael Gilligan provided the link to.

Extract from 18/12/2014 thread, 0MT drill chuck
A photo of my turned down, cut down RDG arbor ready to fit to the chuck

Thats very good..Wish my little lathe did tapers!I was wondering about cutting the top off, leaving the narrow part the right lenght then welding a little blank on and use a die for the thread..Then I realised I need a straight shank with a 0mt to get it in the lathe chuck to turn it .I m on the trail of a short one..
|Thread: Super adept lathe|
The cross hole that is mentioned is, for me, quite important. Stick a tommy bar through it and it makes it easy to extract chucks, centres etc. from the tailstock. As you wind back the barrel the bar strikes against the nose of the tailstock and out pops the chuck, centre, why.

|Thread: Up and over door seal|
Its worthwhile checking the door construction.
|Thread: Anyone recognise this mains connector ?|
The pity is your plug will cost more than the furnace!
|Thread: Is this chuck too big/heavy?|
The thing that will really test you bearings (and lathe as well), seeing that its an independent 4 jaw, is mounting a relatively heavy job off centre to the chuck and then running at too high a speed. Your centrifugal forces far exceed the static loading!
|Thread: Silvering brass|
Can anyone shed light on a process I vaguely recall for crack testing Brass Cartridge cases. Cases were either dipped or rubbed over with "snake oil " that turned them silver except where there was a crack ( from the deep drawing process) that appeared as an uncoated line. Rejected of course!
I seem to remember that mercury was involved so the whole process will be considered "iffy" today.
