It's not just the watch itself that is in bad taste. Romain Jerome used to have a big Titanic DNA poster up in Geneva airport that said something along the lines of "Celebrating the loss of the Titanic". Presumably they meant commemorating but a little more thought mightn't have gone amiss

Thread: Toolpost grinder tips?

Hi Jon

Absolutely don't need it in the slightest. Was just messing around with the thing to see if I could get a decent finish

Cheers

Thanks Steve. Tried various speeds this morning but not much improvement.

Ian, I was coming to the conclusion that, as you advise, I need a finer grit wheel to get the finish I'm looking for. I did dress the wheel but that didn't make much difference. Trouble is the wheels don't seem to be a particularly common size (80x10x20). The grinder is 250W (input) running at 6000rpm

Evening all

Does anyone have any hints and tips for using a toolpost grinder. I've been messing about with a grinder for a mini-lathe but can't get a particularly good finish. The grinder has an 80 grit 80mm wheel. Is 80 grit too coarse for a smooth finish?

The photo is a blank arbor that I've ground first dry all the way along and then the outer 2/3 or so was ground with some lubricant which gave a slightly better finish. The lathe was running at 2500rpm and in the opposite direction to the grinding wheel.

I found a previous thread where Graham Meeks comments have disappeared and it never really came to any conclusion so any additional hints and tips would be welcome.

We used to use zinc chromate to prime galvanised handrails on ships. Haven't seen it for years

Just a quickie Jason - what grit would you go down to?

Hello all

Just wondering if anyone has any tips for getting a good finish on crank pins and journals for I/C engines?

Thanks

Hi Hopper

I'd be interested to see a pic of this "cloverleaf" plate if you're able to once PB is back up.

Cheers

Lofty

I don't doubt that the training is far superior in "Grey Funnel Line" but sadly the same can't be said of the commercial side. I agree that there is little need for it on board these days and yes, it's definitely becoming a case of throwing new bits at it or getting a contractor in.

Our company is considering sending newly qualified engineers to a shoreside engineering company for six months hands-on experience of fitting and machining because the training they are given to get them through an MCA Certificate of Competency isn't equipping them for the practical aspects of the job. They're all good at filling in forms on computers though! smiley

Scott,

I have made precision parts on board a ship with the ships lathe, one was a pump shaft about 18" long with several different diameters two for ball bearings and a keyway (cut on the lathe) on one end and an assortment of other things. People on board said it could not be done so just to prove a point....

Fair play to you Bob. I've sailed with a lot of older engineers who used to use the lathe a lot more (screwcutting valve spindles and all sorts) and our lathe is actually reasonably accurate despite the abuse it gets. Unfortunately most of the younger generation of marine engineers these days don't have enough machine shop training and experience to really know what to do with a lathe and it's highly unlikely they would be worrying about the accuracy of the thing. As with most training these days the system is letting them down.

That said, they have lathes on board big ships !! So what do I know.

and trust me, there's absolutely no precision work done on them! smiley

Turning/threading screw-in zinc sacrificial anodes for jacket water systems is about all I see them used for these days. Not much else

I fixed up an extra CCTV camera to cover a blind spot on my existing set up.

Me too!

Had a bit of a mooch around the Engineering Shop in A&P shipyard in Falmouth. Some antiques still in use there!

Thread: How to cope with a disaster

A Doxford Clive??? That was neither today nor yesterday! wink I've been at sea 30 years and never heard of one that was still going!

Good advice about anchor cables though. Windlasses are designed to have the capacity to lift all of the chain in the locker if it's hanging vertically out of the hawse pipe but by the time they've seen a bit of use it's unlikely they would. Walking the cable out is a recognised technique for trying to influence the drift of a disabled ship in deep water though.

I've heard of ship's running to a more convenient port for repairs with one unit in the engine disabled but never seen it done myself.

Danny

Any vibration with yours? And how good is the finish?

Cheers Rik. Dressing it didn't do the trick so I think I'll bin it and get a decent one. It's a real scabby looking thing anyway. All moth-eaten round the edges.
