    FWD gets new shoes

    Bob - on most UK commercials, the tyres are standardised sizes, with press on bands. The wheel diameters that come to mind for me are: 670mm, 720mm, 741mm, 771mm, 850mm, 871mm. I'm sure others here know of more. I've also come across some Goodyear solid tyres, which are sized by the OD, but are still press on.So it could be that they are press on tyres for standard rims? I'd guess you're probably much too light to worry about it, but one thing that does require caution with solids is that the compound (and presumably hardness) needs to be reasonably equivalent to the original ones. Heavily loaded and at "high" speeds (20-25 mph), after 20-30 miles the tyres can get very hot, and I've seen the results of a solid tyre overheating so much that it burst. A huge mess, with molten rubber spraying out and adhering to what it landed on. My guess is that it's related to the tyres being softer than original, which means you get more heating through hysteresis.

    1911 Dennis Fire Engine 3035

    Andy, I totally understand and don’t disagree. Another way of looking at this is “period of significance” - as a fire engine it was a prominent vehicle, rather than a cobbled together piece of agricultural equipment. To share a personal story, the Garrett steam wagon that my family owns worked for about 8 years commercially, was laid up for about 6, and then spent about 35 years sans boiler and engine as a trailer for a sterilising boiler in a nursery. Of course, it’s restored to more or less “as built” condition, but my Dad has wryly observed that it spent most of its working life as a trailer, and that’s almost certainly the only time it actually would have been profitable for its owner!

    1911 Dennis Fire Engine 3035

    Can I offer the perhaps unpopular suggestion that you could consider keeping the Merc engine, and restoring it as it was late in life? The Merc is a presumably significant part of its survival, and it’s an authentic part of its unique history. Grafting an incorrect Dennis engine in there is making it into something that it never was. We sometimes as restorers have a tendency to want everything as original. My grandfather used to own a Fowler ploughing engine from 1868 that had been fitted with a Burrell cylinder in its working life. When I was young I’d always wanted to see it as original, but in fact it’s much more interesting and a unique survivor as a hybrid.

    WW1 Thornycroft restoration

    Couldn’t it have been forged in two or more pieces and forge or electric arc welded?

    Another Thornycroft

    Ben - looks like another interesting project! The JAC mark has been touched on here before. On our Garrett wagon there are a lot of steel castings marked “JAC”, and they are believed to have been cast by Catton’s foundry in Leeds.

    It’s a Scammell tractor.

    Steve, I don’t have the details on the engine, I’m afraid! The radiator is indeed new. I’ve not seen the Knox in person yet. The thing I was struck by from the photos (and by Dad’s description) is that it’s enormous. The top of the radiator is about 6’ off the ground!

    Hi Everyone - I thought there might be some interest in these updated photos taken this weekend. As you can see, there's a great deal of progress! I don't have any specific technical updates... but as ever, any new info, parts, drawings, photos, etc would be of interest!

    Not uncommon. Our Garrett wagon is the same.

    Could always go and get some white lead, Tomo! Call it a "work of art"!

    WW1 Thornycroft restoration

    If the piece in the middle of the photo was laid on its back (same orientation as the piece on the right) for ramming up, then it will leave the core print exposed at the bottom. The core goes in, then leaving a space behind for the part, and the other half of the mould is just flat sand. Right?

    WW1 era Commer chassis on eBay: https://www.ebay.co.uk/itm/292237556049 Looks like a good potential starting point for a project!

    WW1 Thornycroft restoration

    We steamed the rail around the front of the Garrett cab roof, which is about an inch thick. A big piece of plywood with some blocks on it as the 'mould', and a couple of hours in a piece of old flexible chimney liner with the end stuffed with rags, with steam from the boiler in at the other end, and it worked fine.

    WW1 Thornycroft restoration

    Yes, although these were white metal. https://www.artisanfoundry.co.uk/product_info.php?products_id=205 We are fortunate that we know what all of the casting marks should be, so we try to put them on when possible.

    Steve, have you considered making an oddside? I was inspired by your threads on here to make some patterns for the Garrett. I made one handle (a smaller one than this) as a split pattern, but then I was told about an oddside (the part in the middle row, on the right). The idea is that rather than making a split in the part itself, the oddside defines the split; the first half of the mould is rammed up against the pattern, with the pattern in the oddside, and then the oddside is removed for ramming up the second half. The way we made it was to trace the outline of the part onto a piece of plywood, and then cut out with a coping saw. The back was then filled in to make it sturdy enough for ramming up. It only took a couple of hours to make, and it should make the mouldmaking process easier (and perhaps cheaper?).
