Thread: The death of Diesel?
25/10/2017 14:07:13
Posted by ChrisH on 25/10/2017 11:12:44:

Yes, 30-40 years ago a life at sea was good, especially for a single bloke, good looking ships (none today look good), decent sized crews and long time in ports. The engineers used the time in ports to overhaul the main engines which had large maintenance requirements and the long time in ports meant an opportunity to 'relax' during a voyage.

However, for us ex-sea going chaps, a way of life and the beauty of the old ships have gone forever, the British Merchant Navy reduced to a very small fraction of what it once was, by a combination of containerisation, modern technology and EU restrictions on our trade (on the trade we once did before we joined the 'Common Market', as it never was, with all our world-wide Commonwealth countries).

Aha, another ex jolly Jack. Remembering the good old days!

Sam

If the shaft is one of those that the print head traverses on, it will be as hard as hell on the surface.

Very interesting observation, that. I've always thought that they were Stainless of some grade. I've got quite a stock of printer rods in various diameters and from different makes and have never had any problem machining them and getting a very good finish using HSS tools. Guess I'm just lucky.

Thread: ML7 Cabinet\Stand
24/10/2017 15:05:39

I have my Myford lathe on the cabinet stand with raising blocks and found the operation uncomfortable because it was too low for me. I'm 6ft tall. Problem solved by bolting the stand on 2" x 2" hardwood laid front to back. This also cured any possible instability issues. The lathe is free standing on the floor without problems.

Thread: Wabeco D4000-getting a lathe upstairs and first impressions.
09/09/2017 09:27:57

In reply to Martin, above, I must say that any questions that I had about my Wabeco mill have always been answered courteously and promptly by Bryan at Pro Machine. If he could not give me an answer straight away, he would always get back to me when my query could be answered.

Still doesn't solve the quality issues with the machine, though.

Thread: Making a new mill over arm, accurately measuring long distances?
06/09/2017 22:14:59

If you have or can borrow a copy of GHT's book on making the Universal Pillar Tool, he explains how to make a cotter. They are used to hold the arms to the column and column to base.

And another thought.

We had a major power cut this week over a big area. Dorset is hardly remote, but is 'the end of the line' for the national grid, and such cuts are not unusual. What would happen to my trusty Tesla ( or a recycled milk float, which is more likely)?

Still an EV fan, and will be moving that way as sooner as we can do it reliably- and that is pretty close. (Need something big enough to get an electric piano in though).

You hope it's not night time and use your solar PV panels. Or connect your hamster's wheel to a charger/inverter.

Thread: What Material for 5C collet Rack
22/08/2017 23:26:29

My set of ER32 collets arrived in grease proof paper - or whatever the brown stuff is called, so a storage board was needed. I made mine from a piece of white 'plastic' food preparation board. Just drilled a series of holes slightly smaller than the max. diameter of the collet. The sides are tapered to give a slight angle for easy selection and they are screwed to the main board.

No chipping or oil soakage sith this material and it's easy to keep clean. Only possible downside is that I can't attach a size tag for the collets to the board - glue won't stick!

My Pratt Burnerd Gri-Tru chuck had the cavity filled with grease from new. If grease is good enough for PB, then it's good enough for me.

Thread: Restoring chrome plated hand wheels.
14/07/2017 11:23:41

I had a tatty handwheel on an old tailstock where the chrome was missing in areas around the rim - not worn but 'chunks' missing. I was surprised at how thick the plating was and how difficult it was to get the remaining chrome off.

After a while trying to chip the old chrome off and also using various abrasive substances, I gave up and sold on the tailstock with the wheel in much the same state as when I got it. The edge bits were very sharp and I cut myself a couple of times but I'm still alive to tell the tale.

Thread: What Lathe Sould I Buy?

3 phase motors are not a problem these days, so don't let that put you off. A VFD (Variable Frequency Drive) will enable your 3 phase motor (subject to original motor power, but up to 3 h.p. should not be a problem) to be powered from single phase mains and among other advantages, speed control of the motor is infinitely adjustable.

Thread: Abrasive polishing sticks
10/07/2017 23:10:41

I've made a small external hone and the piece of al.ox. is the abrasive. 3mm wide would be OK, but nothing wider for the size of tool.

10/07/2017 14:08:47

I'm looking for one piece of aluminium oxide polishing stick used in EDM processes among other things. The size I require is 1/16" x 1/2" (or 2 x 12mm), either 4 or 6" long and grade 320 or 400.

I've done a google search and have found some suppliers but they will only sell in minimum quantities of 12 pieces. Even the one piece will last me several lifetimes use.

Can anyone point me in the direction of a supplier, preferably in the UK but I have no problems with the Far East or USA if postage is reasonable.

Electric goods vehicles were on the UK roads in the 1960s and 70s in quite large numbers: the humble milk float!

It's good to have another member from the other side of the Irish Sea. Whereabouts in Ireland do you live?

Thanks John. I have heard of BMS 'unstressing' when it is machined, Ill try for black bar when I come to it

And bash the bottom thread with the ball of a hammer to deliberately damage it so that you can't run the bolt all the way through and possibly damage the slot.

Have you tried the PM Research globe valve? 1/4" x 40 thread available from Forrest Classics
http://www.forest-classics.co.uk/pm_research_sw-4.htm#Globe%20Valve

or if you fancy machining your own from castings, have a look at PMR
https://www.pmmodelengines.com/shop/pipe-fittings/globe-valve-kits/

They are easy to make up.

Why not have a go at making your rotary broach following the ideas of mike's workshop?

Doesn't look too involved.

I have just come across IMGUR, a site that hosts pictures for 'free'. Don't know whether this would be an alternative to Photobucket.

Thread: Milling in a pillar drill
03/07/2017 11:44:39

Most small hobby milling machines are frequently called mill-drills because they have the rigid requirements for milling as suggested in the previous posts. They also have reasonably good head room to allow drilling operations on the majority of jobs.

If budget is tight, get yourself a suitable milling machine and sell the pillar drill to offset the outlay. You can then use your newly acquired tool for its multiple intended uses.

You will amazed what you can do with a Transit.! I worked for an engineering company in the 80's and we had a fleet of Trannie diesels, a driver phoned in broken down with 40 cwt steel on board, I went out to tow him in with another transit loaded with 30cwt of steel and we towed it back home 60 miles with no problems at all! That's when Ford made proper trucks!

Aye, and they go round the Nurburgring pretty quickly, too. (From Top Gear about 10 years ago!)
