Just finished some 7075 alloy parts for Triumph triples. Apart from the swinging arm end caps all the rest are engine internals. There’s a plethora of nuts as there will be a load more studs next week, i’m just waiting for the bar to arrive so i can make them. The stator towers took some concentration as they all need […]
I’ve made a set of titanium exhaust studs for a Yamaha R1 and 7075 alloy nuts to go with them. The studs are M8 thread into the head but M7 to take the nuts. The nuts are Surteck 650 coated for corrosion protection. The studs weren’t the easiest things in the world to make, there is very little plain shank […]
I’ve been working on some titanium parts for 500/4 and 350 twin racing Hondas. They are the sprocket drive pins, engine mounting studs, chain adjuster studs, front fork spindle cup studs and rear brake cams. The cams were fun to make, if a little taxing! I’ve also made some tappet adjuster nuts in 7075 alloy.
Here’s a titanium rear wheel axle with nuts and swinging arm spindle for a Ducati Monster that i’ve just cooked up. The swinging arm pin is a tough one as its so critical on diameter. It runs through needle roller bearings so the accuracy has to be spot on, 0.005mm clearance.
These engine mounting studs are 380mm long. Happily the engine plates and castings are bored 1/2″ so I left the shaft full diameter and turned M12x1.25 threads on the end to match Probolt flanged nyloc nuts. It would have been incredibly difficult to turn it down to 12mm over that distance leaving a good and accurate finish.
I mentioned in an earlier blog that i had a set of Ducati cylinder head studs coming up, and here they are. These are going off for coating so he should be able to get a good torque setting on them.
Heres a pair of 7075 alloy push rod tubes i’ve just made for a Triumph TR650. Theres some slight modifications on them as my customer is using thicker base ‘o’ rings. These aren’t polished and coated as they will be painted.
These titanium castle nuts are to hold the wheels on a car. i don’t have any more details than that, but i think its a racing car.
Heres another pair of swinging arm axles for a Montessa. The longer one is for the two stroke version, its 15mm longer than the four stroke. These have been Surteck 650 coated for corrosion protection.
I’ve just finished some more parts for a Buell. I did the spindles last year so now its nuts and bolts time. The trouble with Buells is they are a mixture of imperial and metric threads. No problem to me as i can cut just about any thread you care to mention, but you can’t get off the shelf titanium […]
