|Thread: Myford 33t and 34t gears for metric threads|
The 33T seems to be available.

It seems the 33T is available from RDG.
|Thread: Round indexable tips.|
|Thread: The Diamond Tool Holder|
I have made two of them, excellent tools. I use them for finishing cuts.

|Thread: Cutting a large chunk of nice aluminium into workable pieces|
Lucky you. A friend got a similar thickness off-cut of marine aluminium alloy and we used an angle grinder with an abrasive disk intended for use on aluminium and its alloys. A few cuts were made using a hacksaw, we had less than half your temperature though. I have used a chunk of it to make a housing for a small turbine I'm working on.
I had a look in your album and the carriage and compound slide looks very nice, well done.
|Thread: Use of Colour on Drawings|
My preference would be No 2, as Andrew I think No 3 obscure detail and makes it more difficult to read for my old eyes.
|Thread: lathe to cut 26tpi|
Welcome to the forum. You don't say what your budget is but may be a lathe with a 10 in. swing, and I assume you want an imperial version if you cut a lot of imperial threads. If you want a new lathe the Warco 250V is one option and seems to be available in an imperial version. A second hand British made lathe in good condition would be another option.
|Thread: Boxford VM30 manual wanted|
It seems you can buy the manual from lathes.co.uk .
|Thread: Milling feed/speed question.|
I made a typo in my previous post, should of course read: "....you could probably use 1500 may be 2000rpm."
I have a Sieg X2 and usually take a light finishing cut to get a good finish, and use a higher speed for the finishing cut. For a light finishing cut in free-cutting brass you could probably use 1500 may be 200rpm. There is a speeds calculator here, and see here for feeds.
|Thread: Practice facing|
Brazed carbide tipped tools may need to be sharpened to get a good finish, you can use a "green wheel" to grind the cutting edges and then I use a diamond hone. This improved my brazed carbide tipped tools. If you have some HSS tools they can be sharpened with an ordinary wheel on a bench grinder and honed afterwards. As you say, cold rolled steel may not be the best metal to turn, try and get some freecutting steel. When facing you should ideally increase the speed as the tool approaches the centre of the work, so if you have a DC motor or a 3-phase motor with inverter just adjust the speed.
|Thread: Completed Twin Inline IC Engine|
That's a very nice engine, impressive.
|Thread: Silver solder flux|
The oldest silver solder flux I have is over 30 years old, still works. So just try silver soldering a couple of leftover steel pieces together to see if your old flux still works.
|Thread: Tapping Drill Sizes|
The tapping drill size I use depends on the material, for tough materials like stainless steel I use larger dill sizes than the ones you listed. For free cutting materials I use the drill sizes you listed. Using a drill size 0.1mm larger will reduce the chance of the tap breaking and the reduction in strength is very small.
|Thread: Its that time again|
Same to you Martin, and all the other forum members.

|Thread: Lathe crash!|
On my 290 lathe the manual says Mobilgear 627 or equivalent for the gearbox, I have used ATF on mine and use the same oil in the Apron.
|Thread: Telephone / Internet Scams|
I have had phone calls similar to yours, different number though.
|Thread: Warco WM 280V Variable Speed Lathe With AC Motor Inverter Drive|
I have the 290 version (different colour scheme though) with a 3-phasemotor and inverter. The lathe has served me well for the past 5 years without problems, I like the 38mm hole through the spindle and the ability to change speed while making a facing cut. A better spindlenose would be welcome as would a gearbox that had more than three gear ratios.
|Thread: Vickers Bl 8 inch Howitzer cannon of 1917|
You have made a good start so far, looking forward to see the rest of your build.
