Horn Casting bolts doh...

[Rotor]

Everthing has been going really well the clean up and rebuild untill today snapped 3 of the six bolts even after soaking with
pluss gas, cleaning around with a tooth brush and feeling them out turning back and forth.
Bum ! Pants! and GRRRR !

If there is any thread showing MIG weld a nut on and try again.

One of the three has some thread, looks like I'm driving around the local industrial estates this Saturday morning. The sad thing its in original paint, and the paint is in fair/good condition, going to feel awkard asking some guy to mind the paint, when off the scoot it looks like a piece of 50 year old scrap !
Wonder if any off the dealers provide a service for this kind of work..hmmm?

Simples..pop into an engineering shop and ask them to use an easy out tool, no paint damage at all..(its a left handed tap of sorts) I've just had horncast/ head set nuts and headset snapped nuts removed at work..

Found an engineering shop today, greeted by a guy who says 'looks like its part of an old Lambretta' bingo good start here, he was very confident he could sort the three bolts after a quick look, and followed by it will be £25 and a few days . I will call back next wednesday even beter he says. Will let you know how it goes next week !
A fair price i think for the work, when a copy horncasting is arounnd 90-100 pounds

I have a tig welder who works for me in his late 50s who is an old scooter boy from the 70s and although he rides a harley nowadays is revelling in repairs to my various Jet bits at the moment, he is just in the process of rebuilding my horncast which had a large chunk missing from the bottom were the grill fastens to and the results so far are amazing as he builds the ally back up and will re tap for fastening to mudguard and grill fastening..

I tried one of those stinking left handed easy out things on my snapped horncast stud and snapped the easy out in the hole I drilled in the stud, the easy out is rock hard and won't drill like the stud did, think I'll find an engineering place in future

Eazee-out's in small sizes are always a bit iffy. Like Wack says, weld a nut or even a bit of bar end on which you can apply visegrips to. Done with a bit of care, or part wrapped in wet rag, paint damage can be minimal. Its the heat/differential expansion that helps break the seize, but a splash of P-G while still warm will draw it into the problem area. You can snot the end of the fastener before you try anything else if you know it's likely to be problematic.
Using the PlusGas type products, time is what you need, give it a blast and leave as long as possible, overnight minimum, a week is better. Arrange part so stuff dribbles in, not out.
Some one did a comparison between brands, I think diesel/parafin and paint thinner came out top.
