Posted by on Nov 26, 2013 in News | 0 comments

Along with the oil cooler bolt below, my customer also wanted a set of exhaust nuts in 7075 alloy, and here they are…. They are M7 thread, i’ll be making the studs to go with them as well soon, they are M8 into the head and then M7 of course to accept the nuts.

Honda BR1000 7075 alloy oil cooler bolt

I’m still on with a shed load of 7075 alloy parts. I want to do all the alloy work i have in so it can all go for coating as one batch. This is an oil cooler bolt for a Honda BR1000, its a direct copy of the HRC one, but weighs 80g less, the HRC is 130g and my alloy one is 50g, worth doing!

Yamaha TDR titanium steering stem top nut bung

Posted by on Nov 21, 2013 in News | 2 comments

This is the final entry for the SP2/TDR head stem and steering head furniture, its a plug i’ve made to cover the top of the stem for the TDR/CRF head stem conversion. As the finished length of the new stem was hard to establish accurately without having the frame to fit it all in, i erred on the short side. This is one of those rare times when it will be easier to add metal on (by making the plug) rather than take metal off, if turns out too long then it will be a struggle to shorten it. Mechanically the length is enough to give full and robust support to the top yoke, but short enough not to protrude beyond it, i...

Suzuki DR 7075 alloy steering head stem

Posted by on Nov 20, 2013 in News | 0 comments

I seem to be repopulating the world with alloy head stems at the minute, here’s one for a Suzuki DR and then there are 5 more for AJS 7R’s that i’m on with making right now, so you’ll be sick of the sight of alloy before i’ve finished. Good job there’s lots more titanium parts coming up!   So the new 7075 alloy one is 515g lighter than OEM, no wonder i’m making so many!

Honda SP2 titanium swinging arm axle and adjuster frame inserts

Posted by on Nov 20, 2013 in News | 2 comments

As part of the order for the 7075 alloy steering head stem for the Honda SP2 my customer also wanted a swinging arm pin and the large adjuster inserts that live in the frame. The adjuster pieces were not so straight forward to make as they have the large 21mm A/F hex socket in the end. Broaching the hex in is tremendously difficult as i do it on a fly press, so i had to make holders that would take the strain without deforming the inserts. They came out well though.   He also wanted the chain adjuster bolts and nuts, so i made those as well   and finally a new front axle bolt. I made him one a while ago to OEM dims, but then he fitted Ohlins forks with beefier axle so the head of the original bolt is too small, so i’ve made him this one with a bigger flange, sorry about the...
