    Cold Bluing Parts

    As an avid shooter I'm quite familiar with cold bluing. It's widely regarded as a very poor relation to a proper hot bluing job. I once owned a gun blued by Purdey (the people who make 6 figure shotguns). The finish was flawless and deep and so much better than anybody-elses. I'd suggest heavy...

    Tilter mk3

    Thank-you. It's not as stable as a regular tadpole, hence the damper. Ackermans are much less important due to the leaning. The scrub is not overly noticeable and tyre wear is fine. If there's any realistic way of sorting the Ackermans then it's evaded me anyway. It's fairly stable up to about...

    Frontrunner build question

    I would think that at 6'2" you'd want to set the adjustment nearer the rear than the front but keeping enough overlap over the clamps for safety. Most others are likely to be shorter than you.

    Quad build.

    Cars with "two" chains driving the cam are actually just one chain called a duplex. It has two drive aspects but the chain is built in one piece. They are used where a regular single chain of the same single part dimensions can not cope or extra safety is needed due to the critical nature of a...

    Quad build.

    Indeed asking a single bike chain designed to take at most 400W from an elite athlete to handle 2000W is a tall ask. The problem with a second one is that only the tightest will take the load. The slacker one will not take any load until the tightest one has worn enough to equalise the tension...

    Self aligning bearings help needed

    The rumours of my demise have been greatly exaggerated. I too would use a straight bar with the bearings on and them then bolted to new uprights which then get welded to the existing chassis. Check regularly for rotation whilst welding the uprights on and adjust with a hammer if needed. Weld...

    Catamaran 2 fat bikes into a Quad

    No reason why it can't go there. It does mean the derailleur could be vulnerable on break angles if tackling dunes as it'll be outside the wheels circumference. It could be a problem if you are going up and down dunes and may need some protective shielding.

    Quad pedal race car - refurbish and improvement [ I hope ]

    That's a lot of grease. A car would have the diff in oil. Samagaga says these are maintainance free. Do you know if that is Samagaga grease or if it's been opened before?

    I‘m really having issues tracking down front wheels for a Streetfox

    Link now working. They are a little odd in appearing to have a disc mount either side of the wheel. You could also do similar to Brad and use an m14 bolt and weld a small section of 20mm x 3mm wall precision tube at the bearing support points.

    Catamaran 2 fat bikes into a Quad

    Given you are now using steel framed bikes why not use steel for the rest and weld it. Going wider means longer beams across and aluminium makes really poor beams. You are using it off-road so forces are likely to be higher than road use with the potential for accidents and flipping with the...

    I‘m really having issues tracking down front wheels for a Streetfox

    No working link there. Usually 20mm disc hubs are about £20 on AliExpress. Do as Danny did and lighten the axle. It's simple to build a machine that is too heavy.

    I‘m really having issues tracking down front wheels for a Streetfox

    Almost all 14mm axled 20" wheels will not have a disc mount. They do exist and are just slightly more common than unicorns. Three options:- Use 14mm axled BMX wheels and bodge the disc mount by getting wheels with a thread for screw on disc adapter. You need to bolt the disc adapter through the...

    Quad build.

    Increasing the distance between the bearings for the rear axles would increase rigidity. With them being close any give or bending in the mounting of those bearings will have a large effect on the orientation of the wheel.
