Hi love your channel, I have an old fishing boat here in New Zealand, (Picton's Northern Star is my Channel) She has I believe a Gardiner 6LXB that has probably done as many miles as it would take to circumnavigate the globe-lovely old engine and I am sorting through few issues including a $30,000 rebuild of the reduction and gear-box last year. I am a handy-man only, know very little about engines-diesels, learning as I go, the reason I started my channel is that people would probably be quite entertained by my naivety and other issues I encounter...The current issue is I believe the electrics are 24 volt, new batteries across the house and starter-bank as well, I noticed parasitic draw on the house-bank which led to me testing the starter-bank and then the alternator after watching your video, It seems the engine-alternator is charging only sufficiently to keep the two 12volt batteries in the 24-volt starter system at 12.75 volts and then little to nothing crossing over into the house-bank set-up which is dropping to 23.7 volts, I got into the engine room with the volt-meter yesterday and checked while the engine was running in idle and at 600rpm and found a maximum voltage off the rear of the alternator of 15.6-something to 15.9-something volts, Would I be correct in thinking this should be at least 24 volts plus generating off the alternator to recharge the starter bank then top up the house-bank, etc at the moment it seems only sufficient to keep the level up to 24.7 volts in the starter-bank I can send a photograph of the alternator if that would help, I believe from your video a C% model. I am wondering whether I need to pull off the alternator and send it away to be serviced, or whether I am missing something here, is it only supposed to charge at around 15.9 volts, sufficient to charge a 12 volt battery? Would value your opinion

As a diesel mechanic, I would like to say as a word of warning, NEVER start a diesel engine with no coolant in the block, even if it’s only running for 20 seconds. A run of more than 5 seconds can cause serious damage to the head and tops of the cylinders, I have seen this first hand.

lol. That old Coach engine sound or Bin lorry’s. lol Everyone talks about. GERMAN This and GERMAN that. Truth is we Built incredible modular engines. And simple . Just like the Roman aqueducts Bridges and general Architecture it lasts. Modern stuff says. Ooh it lasted 60’000k miles. Amazing. With basic maintenance a Gardener Marine engine will last Hundred years. Of continuous use ( without over stress and with decent maintenance oil diesel filters etc. will last the equivalent of 6 million miles.

Hello. Mr. MCOOL, your channel is very, very interesting. I come to you, I have a boat with two Gartner 6 LXB engines. One of which I have a problem with the speed when it is loaded, it does not take more than 800 rpm. On the other hand, when empty, it climbs in speed. Could you guide me on this kind of problem, cordially and thank you.

Hello Mr Mcool. RIP your Boy. . It seems like you don’t Run a channel anymore. . Been waiting for further Gardener engines Land or sea .. my connection with these Was working as a diesel fitter for a laundry van / Bread van . Servicing company. We worked on the old 3penny bit cabs with the Straight 6. Or the 4. Old diesels. . The 6 cylinder used to throw rods. The 4 cyl never broke these old engines. We’re used just like the Engines yoyr working on. Old ATKINSONS ET. MANY COVERTED INTO canal boats and trawlers. Every Suffolk Coastal lugger had old gardener or Denis Atkinson Perkins engine. Run for ever . Post some more old man please

I used BA screws a lot when I started model engineering in the 1960s, and my father gave me a boxed set of Triangle Brand taps and dies which lasted me about 40 years (Sheffield manufacturer). I later changed to completely to ISO Metric (M1.6 to M12) for all my projects, although I still keep a selection of prehistoric taps and dies (BA, BSF, BSW, UNF, UNC) just in case something odd crops up.

BA screws? They have been a lifetime favourite with me but that said, they lean heavily on a set of Swiss clock and watch threads. The diameters come out in sensible numbers in millimetres and wierd ones in inches. Keep up the good work!
@glynluff2595Ай бұрын
The point of BA screws is that they use a Swiss designed thread which has a male/female format. When you get down to 6 BA the advance return on on one revolution is a known number of microns. The male/female format means unlike other threads they will not move when relaxed. So if used as a calibration screw on electric or electronic equipment they can be left when correct. Their thread rate is 471/2 degrees whereas Whitworth is 55 with a rounded edge. However, in WWII UNC and UNF were devised because while the Americans liked the Whit sizing the 55 round edge could not be mass produced by rolling. Consequently UN formats had 60 degree sharp edge format as with Metric. Post war with Britain exporting to the USA as tooling for war use was already in UN format it was retained by the motor industry. That is the rough history of threads as I have unravelled over the years working my way through industry from which I am now long retired!

@ I agree but some things never change. Look at oil threads all bsp or not plain or tapered. That is from a different industry. Many problems come from part bin technology. Someone likes a door handle when designing. Parts engineer says Hills or some other supplier has something close. They dig out sample last used on say, Austin in seventies. With tidy over it does the job. Thread rate bsf because that was standard then. As for dissimilar metals how long do you want it to last. Today cars are made for 5 year life. Pass on at three and pass again at five. Nobody cares and that is so world wide! Why do we import Japanese vans for auto homes? They are scrapped after three years if they stay in Japan so cheap export. Remember, only the British expect their car to last fifteen years! On top of that you have purchasing officers. These are a nightmare. I had one tell me that he had saved money on my production line as he had purchased cheap screws to finish product run 2 years away. The product used terminal screws that were plated. He bought pan head with a metric thread and plain crap metal. I took him to the assembly machine pointed out the assembler would have to be redesigned for such a screw as would the sorter. It would require development time. There was an alternative. One person on a stool putting them in by hand at £10k per year. He had signed the contract without reference to me as production engineer. I shut off that part of the machine and had that part hand assembled. I think we shut the line down early. Long time ago now! That however is how industry functions. Sad isn’t it!

A salient point that your thread chart will tell you is that the BA thread angle is 55 degrees, which is the same as Whitworth. UNF and metric thread angles are 60 degrees. Fasteners are a complete subject in themselves.

@@nkelly.9 It's not a mongrel thread, it's a very rational thread. Metric, but with a logarithmic, not linear, step between adjacent sizes. Each smaller thread is 0.9 the previous diameter. Often, the odd or even series was preferred, as the difference in each step is small. It's a shame it disappeared.
