I gave up on marking blue and went over to felt tip pens after never being able to find a suitable brush when I needed one, another problem was getting the lids off, the marking blue would somehow get in the threads of the cap and usually the cap would split when being unscrewed. I rather like the container, the lid looks to be quite robust. I can see that it cost £4.80, could you please let me know which supplier it came from, I shall get one and invest in a paintbrush and copy your idea.

This may seem a silly question but does your Bantam have a taper turning attachment fitted.

I think they have changed their name from Myhobbystore, I seem to recall it is something like Sarik. You may do better looking on the Model Engineer Magazine forum, which unfortunately is shut down until the end of the week as they are doing work on the site.

Don’t know about inverters but you should be able to run it off a rotary phase converter. I have a Britan turret lathe with a two speed 3 phase motor running the spindle and a much smaller 3 phase motor running coolant pump and hydraulic pump, I am running it from a Transwave rotary phase converter and it runs it without any problems.

Just Googled 7/16 x 28 UNEF tap and there are quite a few available for under £15, one well known supplier was Rotagrip eBay shop.

Rather than using online calculators I purchased a book called “The gearing of lathes for screwcutting” published by Crowood press, author Brian Wood. It doesn’t tell you how to screwcut, it gives charts of gear trains for pretty near every thread you are likely to cut. It is particularly good for Myford lathes. I have no connection to the author, just a satisfied customer.

Done mine in the workshop about a year ago, much brighter and a whiter light, took a bit of getting used to but am very glad I done it. The one thing I don’t miss is the flickering and flashing when the fluorescent lights were turned on, the LED ones are instant.

Unfortunately what Martin Evans drew and wrote are two different things, I am sorry I cannot help as during Covid I cleared out all my old magazines.

I make all my own water gauges and give 20 thou clearance in the fittings and 30 thou in the nuts. I use 60 thou section silicon o rings to seal the glass and have never had any problems. I always check alignment with a steel bar, usually a drill shank, if I cannot get a good alignment I try another fitting, I usually make three or four sets of fittings at a time, while you are set up for doing one it doesn’t take much longer to do a few more, that’s my philosophy anyway, others will (probably) disagree.

I think he means WP, working pressure.

My gripe about Boiler Inspectors is that they don’t stick to what’s in the book and make it up as they go. All the old designs had expansion brackets and firedoor fittings drilled and tapped into the boiler shell. The main thing is does it hold pressure, and if it does, what’s the problem. Regarding 2x shell test, why not? I would complain if it was done every time as there is no need but if a 80psi working pressure boiler withstands 120psi what’s the problem with 160psi if it means it shuts up some jobsworth and gets you a certificate. I would demand though that he writes on the certificate all his reasons for testing to the higher pressure. Thinking about inspectors in general, I have worked in industry all my life and have had dealings with loads of inspectors and they all find it impossible to check something to a drawing, a component can be absolutely perfect dimensionally, bang on mid limit everywhere but that’s not good enough, they will say that the turning is a bit rough, does the drawing call for a particular finish, well no but I would like it better, you can guess my reply, starts with F and ends in off. They just cannot adhere to the rules and sadly some of our boiler inspectors have the same problem.

I have a dehumidifier running in the workshop and like Chris I collect the water during the winter for use in the following running season, however I have been told that dehumidifier water is bad for the boilers, I don’t understand why because as far as I can work out it is only moisture in the air, same as rain is, isn’t it. Can someone on the forum please tell us all what water is good and what is bad for our boilers. The club I belong to is planning to fit a reverse osmosis system this winter, one of our members apparently “knows” about such things and says this water will be ideal for us and save members humping large plastic containers of water to the track every time they run, but apparently the reverse osmosis unit needs the water passed through a water softener first. Fortunately owning a caravan we took the van down to Devon early in the season and on the day we were returning home I filled up both our roll along water containers with 45 litres each of lovely soft West Country water, nearly done myself an injury though lifting them up to waist height to put them in the back of the Land Rover but sadly I have now used it all.

Phil I wasn’t thinking about saving the axles, they are scrap, what I meant was that by re machining the wheels and fitting on to new axles you will be the one Loctiteing them on or press fitting them and you are in charge of the quality, nothing worse than getting a loco on the track and someone else’s Loctite or press fit fails. Your 1 - 6 points I totally agree with. Sorry if I didn’t make myself clear earlier, typing it after being at the dentists and brain must also have been numbed from the injections, on the plus side tooth is feeling a lot better now.

For what it’s worth Phil I think you have made the right decision. It won’t take long to square up a couple of cast iron blocks and bore a hole through them and as for the wheels you have no idea how good or bad the press fit / Loctite joint is at present.

That will do the job nicely Doug. Not surprised you have to move it in pieces, it looks heavy.

Thanks for the information I shall certainly look into it. Last Solidworks I used was the 2006 version. I tried Fusion 360 but it didn’t like running on my laptop for some reason so I ditched it and went with Alibre Atom which I am quite impressed with. A fully functioning CAM would be good.

I leave that sort of thing to my elected representatives, the government of the day. Doesn’t mean to say that I agree or disagree with what they do.

Quite agree with you Ettingtonliam, I don’t really understand the point of the thread.
