    Aladdin's cave of machines to dispose of - help needed

    There is a lot of valuable kit with that lathe, and most of it looks very little used or exceptionally well cared for. If the lathe has not been repainted, then that too is in exceptional condition for what I think must be a fairly an early power cross-feed example. I would expect someone who...

    Aladdin's cave of machines to dispose of - help needed

    Quite by coincidence, after the posting above, I came across an article about workshop disposal in Model Engineer. I only have part 2, in No 4679 - 16/12/202. The first thing to do, unless the workshop is dry and heated, is cover everything in rust prevention oil/WD40, including opening all the...

    Painting aluminum castings problems and questions.

    Glass bead blasting gives a surface that I would think would take paint well. The Phoenix Precision Paint website gives some detailed advice on etch primers, but, if memory serves, mostly about brass.

    Aladdin's cave of machines to dispose of - help needed

    Model engineering societies can often help with workshop disposals. You have the Bristol Society of Model and Experimental Engineers and East Somerset SMEE nearby, and it may well be worth contacting them. For maximum return (and work unfortunately) most model engineering stuff generally sells...

    How Do You Make Tiny Copper Washer Gaskets?

    Yes, Vietti, angle on the parting tool and take a facing cut over the fresh end before parting the next one. But yes, burrs can be a problem. Checking my notes, I put a mandrel (offcut turned to fit) inside the tube.

    How Do You Make Tiny Copper Washer Gaskets?

    I have parted plug washers from tube. Don't forget to anneal.

    That is a very impressive little locomotive.

    Ring grooves

    Just to be crystal clear, when you say plunge then move the tool over, do you back it out before moving it over?

    Seized taper lock

    Put plenty of pressure on with the release screw(s). Then start tapping the pulley and taper-lock smartly all round with a hammer, fairly near the join line. Not too hard, but lots and lots, and it should break free after a while. It could take half an hour. If it still has not come off, hit it...

    Steam engine slide valve

    I am not entirely clear about the question, but I'll have a go. Most slide valves have no, or very little, exhaust lap, so the exhaust cavity would normally match the distance between the inner edges of the steam ports.

    For Sale Vintage Stuart Turner D10 Steam Engine Single Cylinder Vertical Castings

    The kit is far from complete and some of the items in the photo are not even Stuart No 10 parts. At that price, no thank you.

    Sealing cylinder liners

    A high temperature Loctite. I have used 648 for wet liners and valve cages.

    TIM-6 ignition > Arduino

    Why do you want more current carrying capacity than a hall sensor?

    Today I went to buy a file---and---man---

    IMHO the best files are made in Vallorbe. There was a group (guild?) of makers there, but as I understand it, now all under the Grobet name.

    V-TWIN---MAYBE V-4

    For our model engines I recommend alkylate petrol (gasoline). In Europe it comes under the Aspen brand name, and is designed for power tools such as brush cutters and chainsaws. The exhaust in your face is much cleaner, it has a much longer shelf life, and contains no ethanol. Some folk confuse...

    Looking at this, it appears to have Hackworth valve gear. Depending on the layout, the eccentric is either set in time with the crankpin, or opposite it (180°). From the video seems that this one is set opposite.

    HELP, my shop is a MESS

    Since having cataracts done, my wife needs reading glasses. Her solution to the problem of finding them is to have at least one pair in every room.

    Press Fits

    Loctite is a commonly used and usually successful way of assembling crankshafts, even on model locomotive crank axles, where there are all sorts of forces involved. While a calculation may be of interest, 'non-design' loads may well be much larger than normal ones. With Loctited model...

    Press Fits

    In our home shops we are not operating production lines making parts to fit some other item that may be made elsewhere, so as far as I am concerned, an H7 fit and its range for a particular size are of no concern or interest. In any case, the standard fits tables are merely a simplified...

    Press Fits

    I suggest turning (and if necessary, polishing) a bit of scrap to a firm push/wringing fit. The wheel seats (or whatever) can then be machined to an appropriately larger dimension. This way, the tentative feely bit is done in fitting your home made gauge. No need for a gauging lead on the actual...
