I googled Gamet and found it was an Indian based company. I did this when I saw a bargain chuck bearing the name. So now I am confused, is it an Indian supplier or European company? Or are there two separate companies with the same name?

Hello Andrew,

It is good to see you back!

Andrew.

I am not sure what all the fuss is about. I have used Paragon Paint's "Myford Grey" and I find it an exact match for the old Myford paint. That is, providing you T cut the original surface!

The paint is of excellent quality and quite reasonably priced so why look any further?

Andrew.

P.S. I matched the old and new paints using a professional Minolta colour meter and they measured the same.

Hello Vic,

I am surprised to hear you say that Tracy Tools don't compete well on price. I have always found their prices to be excellent for the quality of the tools they sell.

If you have a cheaper source for the same quality, then I am sure many people would be interested to know.

Yes I have a Plasplugs device and I am amazed how well it works. As Clive says it is a plastic unit and quite flimsy, but it does the job of sharpening remarkable well. As long as you take care to get both edges the same length, then I can't fault it.

Hello Howard,

I would be interested in the items and I live reasonably locally.

I have sent a PM.

Hello Mike,

It was indeed Commander Barker! Come to think, I believe it was Professor Chaddock that recounted the story.

I had the reputation for replacing Imp doughnuts. I simply used a crowbar to slot them into place. Took about 10 minutes to change one, if the nuts were undoable.

Not sure if it was G H Thomas or Tubal Cain. It was recommended that the backplate was skimmed on the diameter and the mounting bolt holes were enlarged, giving adjustability.

I believe that in one of the three volumes by "Duplex", a similar set up was recommended plus three grub screws to adjust the centre. I will try to find the "Duplex" drawing if possible.

The Hemmingway kit is maybe the best bet. I made one and I find it is easier to adjust than a Burnerd Griptru.

Quite a few ES holders are actually made from insulating material. There is a leaf spring that contacts the centre pin and a slot in the side of the insulating female portion of the thread. Through which a second leaf spring contacts the side of the ES cap. The mains is simply connected to the two leaf springs.

I used to use a 3M product, to line a vacuum chamber with thick aluminium foil. The material stood 200 centigrade and a vicious low pressure plasma. One needed a chisel to remove it after a 100 hours or so of running.

The reel that I have, says, 3M made in the USA. Core Series 2-1360. It is a double sided black tape maybe a little over 1mm thick. Excuse the mixed units!

This was purchased in the UK with no difficulties.

I didn't do Latin at O level. The only disadvantage was that I was barred from Oxbridge entry, despite extremely high marks in the Scholarship papers. The requirement for Latin was dropped two or three years later.

In retrospect, I am extremely glad that I didn't do Latin! Pity that there were no metal work facilities at my school.

Hello Jon,

I have sent you a PM.

Hello Ron,

Looks as if the lead screw drive has been modified to give you reverse. The 4 bolt mod seems to have been done as well.

I modified a 920 for a friend and I incorporated a Gibralter tool holder. That stopped a lot of the tool movement! The VFD mod also gets you well below 100rpm, so screw cutting isn't such a nightmare.

Nice one ,

Andrew.

I suppose it all depends on what you are doing. In my day job, before retiring, I would regularly measure the thickness of thin films to plus or minus a couple of nanometres. I needed this degree of precision to make sure that the films were fit for purpose.

As far as model engineering is concerned 0.5 thou is as good as it gets as far as I am concerned. For most jobs, a couple of thou would be nearer the truth! Horses for courses.

I have the ML10 version of the Rodney miller. I think Howard has just about covered most things. I am not sure about the "Known defects" Of the Rodney. I use it for small work and find it to be in the same league as any other small mill. Basically take small cuts as it and other small mills are not exactly the most rigid of machines.

As for mounting it on the lathe, I have never given it a second thought. Although I suppose it I smaller and lighter than the ML7 version.

Andrew.

Thanks everyone,

The shank has now been unscrewed! Perversely, I managed to unscrew it by hand. I think all the shock loading and heating persuaded it to surrender to mere unthreading by hand. I can assure everyone that it was stuck tight before.

Thanks,

Andrew.

I have found that cellulose thinners seems to work well on old sticky oilstones. Just leave it in the thinners for several days and the stone is much improved.

I have used a similar system for both taps and dies. Works a treat and highly recommended. As for rusting, well I have a tap and die set in a wooden box from the early 1920s, which belonged to my grandfather. No sign of rusting yet!

In the boxes I have made, I usually use some modern floor varnish, just to make it look nice. The untreated ones don't rust the taps or dies. I use pine for the base and plywood for the lid. Pay no heed to the doomsayers, it works well.

Andrew.

Looks as though I may have to cut it off and drill it out. I have tried shock loading the head with the taper fixed and I am afraid I am going to do some damage if I hit the large spanner any harder!

Thanks ,

Andrew.
