These are for a Yamaha R1, they are 7075 alloy front wheel axle with bolt, oil cooler bolt and a titanium gearbox sprocket nut. They are going on a track bike. They’re coated with Surteck 650 by those good folk at Moss Metal Finishing to provide corrosion protection.
This is a 7075 alloy wheel bearing spacer with bearing holders. The length of the spacer is critical as even 2 thou inaccuracy could cause side loading on the bearings causing them to fail, so there was a lot of measuring, checking and rechecking the length.
These are a set of titanium sprocket drive pins for a Ducati. They have a left hand thread under the flange where they screw into the sprocket carrier, its a bit fiddly but not a problem.
These are some tricky little M6 bolts with waisted shanks, the trickiness is not in machining the shanks but in holding them after to machine the heads. Normally I make the shanks just a thou or two under full diameter so they would be around 5.97mm with the thread diameter 5.85mm which means i can hold onto the shank without […]
Here’s some engine mounting and suspension bolts for Montessa’s, they’re off to H&D racing in York. The suspension bolts are socket cap and flanged hex head, the engine mountings are the long waisted bolts.
These are 2 hefty bolts to hold the outboard motor onto a boat. But this boat is a Thundercat, the ones they race seriously, you know, the ones that fly more than float, they take off for a hundred yards and touch down just enough to take off again! The problem lies when they touch down it rips the motor […]
These are chain adjuster bolts for a Kawasaki ZX7RR, but not just any old Kawasaki ZX7RR, one thats got an ex WSBK swinging arm in it and i suspect a shed load of other WSBK bits as well. Studs like this can be tricky to make when there is no plain shank in the middle to hold on to whilst […]
Here’s the titanium rear axle nut, washer and swinging arm pinch bolt for a Honda VFR800 i’ve made recently, jolly nice they are too! I like making these big nuts and bolts as there’s not much fiddliness and they are impressive when finished. The nut has 46mm A/F and 35×1.5 thread.
Here’s a couple of titanium M8x70 bolts i’ve recently made. Probolt do the same bolt but with only a 10mm hex when my customer wanted 13, so i’ve had to make them.
These are titanium BST sprocket drive pins for an Aprilia, they’ll be raced in America. Twiddly things to make, i had to make a holder to hold when cutting the second thread as there isn’t enough plain section in the middle to hold on to, so it made them a bit more involved and nerve wracking to produce. I’m not […]
