The original Myford rear tool post was a solid lump of iron with a curved bottom to the groove for the tool holder and a curved part to fit, giving the ability to alter the tip height of the cutter. Depending on the tool angle effected the angles the tool had been ground to. A horizontal groove and shims might be just as easy ? The important thing is the rigidity of the set up ! Noel.

If I understand rightly comms was lost after 1h 35m yet the decent takes 2h+ so how is entanglement possible ? Discarded nets ?

One system of ballast detachment was automatic after 16h ?

It has no means of comms on the surface ?

Why is it not painted yellow or orange ?

No means of escape, even if on the surface ?

The "designers" had never hears of Sods law ?

I just pray for the poor souls on board. Noel.

There were it seems numerous ballast release systems, one had a 16 hour fixing that would disolve ! Fancy having no way to escape from the vessel unaided once on the surface ! I fear that a catastrophic hull failure has occured. God rest their souls. Noel

Certainly NOT me ! My thoughts are with the poor souls for whom the search is on ! Noel.

In Belgium there is a deposit on beer bottles, I have 4 crates waiting to go back as soom as I can think of a good excuse ! Noel.

Thanks for this thread Julian ! Having always had an interest in radio and the question of what was received and how, was 1912 a good year for skip conditions ? It seems strange that this story has not been a part of Titanic history bearing in mind how much has been written. Noel.

The dear old Zeus book will give coordinates ! Noel.

depending on your injury had you thought of using a cutting disc in an 115mm angle grinder ? If you have one, they make a hacksaw look very old fashioned. Noel

RTD for tapping Etc, I agree it's pricey but works well and you only need 1 drop - and I'm mean ! Revert to lard ? Like hopper otherwise what ever is in the oil can. If it's a long job in Stainless I may turn on the suds. Noel.

I fear that a lack of both electrical and mechanical knowledge may well doom this project ! A stainless leadscrew spinning at 1000rpm may well pick up(gall) and destroy the whole thing risking hurting the operator as well ! I would try to engage the help of someone suitably competant in the field. Analogies with metal cutting lathes are largely pointless as few have a bed of 5', lead screws are 20mm or more, and winding a carriage end to end in 1min is power travel not cutting. An accurate description of the project, it's goal and ideally a few pictures of what you have so far would enable us to offer better advice. Good luck. Noel.

As a boiler cools a vacuum could be 14.7psi ? Would the feed clacks not draw air or water from the injectors Etc ? The valve that opens when drifting is a sniffting valve ? Noel.

Examine the cutting edge of your insert very closely with a magnifying glass ! It may well be chipped or just blunt. Some sharpening can be done with a diamond lap. Try a different edge, and check tool height. If your tool height was high then it was rubbing and generating heat, instead of cutting.

It's a nice feeling to have something useful, as for making it from odds and sods, if it works so what ?

Good luck. Noel.

For ali it all depends on the wire thickness as to what type of torch you use. I used 1.2mm with a teflon liner, I think 3m torch. Thinner wire may well need a short feeder or gun feeder. For ali I would go for TIG, unless heavy section. Good luck. Noel.

Hammering using a punch on the head to breakup the rust and alli corrosion then try as has been said to slot the head. The important thing with small mounted points or disc is to run them at the correct speed, too slow and they will not work well. If it has a pozidrive head and there is enough of the drive left there is a special tool to get them out. Good Luck. Noel.

Yep ! I have a tank cutter, eclipse I think. Never used. Not sure it would go the O/D needed here. Noel.

NDIY beat me to it ! For good bending you need a wall thickness that will take the strech or commpression, thin wall will just kink. I made a hydraulic tube bender that will happily take 2"NB and 40mm solid. Noel

Hi Mike, I agree with you - more so now than ever ! BUT if you know whats going on it may save a lot of trouble. One can always fit ones self. Noel.

How many drivers understand the vehicle they drive ? The days of several gauges to tell those who understand what is going on in the engine have long gone. Many drivers would not now understand what they were telling them. An oil pressure gauge would have probably saved this engine if the driver understood the readings, and acted quickly, you only have seconds. Many oil pressure switches are to low to save disaster ! There are many engines which would have been good if built as designed - but the accounts spoilt them ! 3 that come to mind are the Ford V4 oil pump drive and the fuel pump cam, the V6 plastic valve train drive and the Pinto cam followers. These problems would only show up after the warrentee had expired ! The motoring world is full of vehicles that could have been good if the accounts had let the engineers build them and increase the price just a little ! Ah well. Noel

I would not consider aluminium as a good choice against cast iron, steel or brass/bronze.Noel.

An 1.5" washer may well be about this dimension ? Try a fastener company ! Noel.
