|Thread: Vulcan bomber XH558 to be grounded|
£200,000 is peanuts for the wing work she needs. I wonder if they have thought of parking her at the end of the runway at Warton, I suspect the work would get done.....
If she is looking for a long term home I am sure RAF Mount Pleasant would love to look after her.
|Thread: Midlands Model Engineering Exibition.|
The midlands show is excellent, expecially if you need something from the traders.
I am not sure if I will go to either Midlands or Sandown as they are too close together and I don't need anything. I am thinking of waiting to the London show.
But if we all did this there would be no shows any more.....
|Thread: BA Bolts|
Sadly BA bolts with metric heads is all too common.
Which is one of the reasons I now make my own (the other being that mine are now all 303 stainless).
Is there nothing stamped in the slot down the side of the jaws?
|Thread: Solar Power for the Workshop|
Whilst I am very happy with my PV system. My advice (even before the FIT value went through the floor) to anyone over 55 is that I would not if I were you.
The panels are very reliable (mine are Sanyo and they have had lass than 50 returns/failures in the 3,000,000 plus they have made over 15 years), the bit that is more likely to have problems is the inverter, which I have a 20 year warranty on . But it is that niggle that later in life it's another thing to go wrong and some trade's men might try to rip you off. Then there is the house sales problem only 50% of your potential buyers may see them as an asset the others will see them as a hideous growth...
To return your money in 10 years with the current FIT you would need a 4KW set up costing about £6K. If you want to be green, it will make you feel good but if you are trying to make a profit I'd leave the money in the bank.

I've had a 4KW PV installation since last Oct, it caused me to re think the heating of my workshop (and house/water). On a sunny winter's day I am normally generating over 2KW and that is being used by my fan heater in the workshop. The best bit is that I am still being paid 47p per unit I generate.
Cleaning? My panels are silicon coated so they are self cleaning, but even so the crud only comes off when it rains, I think I have only given them one hose down this year in March. A couple of other houses locally also have panels but they cannot get up to wash theirs, there was a slight difference < 10% between what they generated and what I generate back in March, then the rain came and has continued ever since.
It was a good purchase, changed my perspective on using power. It is now a case of use it whilst it is free. The workshop was warmer this winter than it has ever been.

|Thread: Cutter Grinders|
The idea of using a 5C sounded like a great idea as I have got a set of 5C's... However, I've just measured the shank diameter of the 5C's as 1 1/4", where as the Deckel spindle bore is only 15/16".
I had also forgotten that the "Tool Room" Deckel has a slide on the end of the pivot arm, which is why the various copy accessories might fit, yours has a fixed arm with only the spindle bore to play with: I would make some sleeves to fit the 15/16" bore and then look to ad a "click" if you are happy with the relief angle you can achieve.
(My machine has a reverse to ensure it is cutting in the right direction)
I am assuming that you mean that it is the version of the Deckel without the second swivel on the base of the cutter holding arm as identified on tony's page here: **LINK**
So the limitations of your machine is that you have a fixed secondary relief angle on your tool and you would have to put up with it on your milling cutters irrespective of the material you are using it for. I am not sure of the angle, someone might know.
I have the "Tool room" cutter grinder, and a set of imperial collets but made up a set of collars to use with milling cutters. Yes you can buy additional collets, RDG do them. There are also various copies of the Deckel around e.g.: http://www.warco.co.uk/73-universal-cutter-grinder, and I cannot see why the accessories shouldn't fit.
The instruction manual for the copy machines is here: http://www.northerntool.com/downloads/manuals/426245.pdf it should provide you with all the information you need to use your machine.
|Thread: Nice smelling cutting oil|
At the College all we did was to add a little bleach to the suds.
|Thread: old Simplex articles|
I think it is wonderful that you want to finish the locomotive your father started.

|Thread: Digital Readouts|
I put two 8" versions on my Prazimat lathe. Other than problems with them turning themselves on due to the cold they work ok. For £54 the pair delivered I cannot complain.
|Thread: whats this tool called?|
|Thread: Rust and how to remove it.|
Forgot to mention....milk and sugar are not required.
Tannic acid, better known as cold tea, is effective against the rust. It takes its time, about a week on a bad case, but is dirt cheap, hand friendly ( well it goes rather black after a week of doing its stuff and you may think otherwise of sticking your hand in), and it does not generate any nasty smells/fumes.
