  1. 1914 Dennis Lorry

    Yes, we have a stretcher and shrinker set in our workshop. They work remarkably well. Here is one being used to make a front wing flange for a Dennis N-type. https://photos.app.goo.gl/QYtJSq0ZatOqrF8S2

    Have you seen the (extremely similar) 1914 Dennis and 1908 Dennis threads? Whilst the 1914 is approaching completion, the 1908 looks like it has plenty of time to run. (I feel something of a link to the 1908, I first saw it in-situ under the house where it was entombed)

    An induction heater would be ideal, but I think that the cheap 1kW ones from eBay would be too feeble for the task.

    It's probably about 20 lunatics reading it 50,000 times. :-)
  5. 1914 Dennis Lorry

    Not in 1914 :-) It might not have enough shear area anyway.
  6. 1914 Dennis Lorry

    Is it possible to change the flame chemistry? A reducing flame should cause less oxidation, but might not be hot enough. Is the real prop-shaft a tube or a bar?

    Here is a supplier: http://www.fhbrundle.co.uk/products/25NOSE2__Pyramid_Non_slip_Nosing_35_x_5_x_3000mm I only mention it because the same place does many other useful steel sections and also sells actual wrought iron in strips. (Or at least they did when I bought some, though it is hard to be sure that it isn't just plain mild steel for making "wrought iron" gates.)

    I am a bit surprised that Thornycroft expected anyone to do that. Our Dennis (admittedly a bigger engine) is impossible to crank all the way round and there is a trembler-coil second ignition system. So you pull it over TDC a couple of times and then turn on the trembler coil, hopefully kicking the engine round fast enough to bring the magneto in to play. I thought that was standard for the time. As for the engine getting stiff when hot, that does leave me wondering about the piston ring end gaps. But I seem to recall that you set those?

    Wild speculation, but as you no longer have the long tube from the exhaust manifold to the carburettor perhaps there is less depression in the choke tube. Does it rev at all (or die differently) if you apply the throttle with the choke-board in place?

    YouTube is probably easiest.
  11. Birmabright (New old stock)

    Interesting thought.
  12. WW1 finds and discoveries

    That's lovely, but I bet the steel tyres are a whole lot of no-fun on metalled roads.
  13. I am fairly sure that amongst the stuff that my dad won't be getting to use up that he collected over the years are some sheets of Birmabright. He was planning to use it to skin a camper van he was going to make on an Austin Champ chassis. I remember us making a diversion on the way back from holiday to pick the sheets up from Birmingham, and we came back with them on the roof of another camper van he had made, on an Austin LD IIRC. The background was that he had been there with his job to fix their rolling mill, and managed to persuade them to give him some as a "special". I don't know what condition they are in after 40 years leaned against the wall in the garage, nor do I recall how many they are. But the sheets are at least 8'x4' and at least 6 of them. I don't know the grade, there may be markings. Is this likely to be of use to the Land Rover chaps?

    Google "twinwall polycarbonate" (or possibly "multiwall polycarbonate")

    Oh, OK. Well my £27 one from Screwfix (which I don't think they sell any more) has lasted years. So I still recommend them, just not the B&D one, it seems.
