    If you get the stubs hot enough (red hot) the braze should become molten once again so you can remove the bolts.

    Brush/scrape it off (with a wire brush/scraper) while still in its molten state.

    You won't soften braze up without melting it. Really not sure a whether or not propane touch can do that?

    I was serious about the angle grinder. Cut off the heads and drill out whatever is left, bit of silver spray paint, new bolts and yer sorted.

    Cheers guys, I have a small brazing kit Nigel, but I am not confident about softening the braze. The bolt heads are round and not to thick, I thought about buffing them down with a flap wheel on the 5" hand grinder and then drilling them out with a pillar drill. I do not want to bugger up the stubs .

    Could not manage to melt the braze with the equipment I have at my disposal , so cut and drill is the way forward. I have one off and it's ok but I have done nicer jobs but it won't be seen.


    It has Paul , a lot of it down to me not tackling the whole bike but doing one bit at a time and not renewing things I should has eaten up the time. But I am enjoying the process as it's the first Bonnie I have worked on hopefully I will ride it near the end of the month....spanners crossed !

    Had a go at putting the head on ,it did not go according to plan . The centre head bolt seemed very tight before torquing , took it back off and the bottom two threads were gone could have been me but I run a tap down the threads and gave it a couple more turns . We will have to see if that improves the situation with a new head bolt.

    Ready for another go tomorrow. I took the oil tank off and gave it a good clean but this has made me think I should have a look at the box and also do the sludge trap bearings shells etc rather than use it with no work to the bottom end as the rest of the machine was in such a poor condition.

    Stuck the head on ,seemed to go according to plan, however my preparation for this job on hindsight was poor to say the least. As I had changed the head the rocker box 1/4 bolt were not the tidy shaped cycle thread but the later UNC bog standard type which I had neglected to try first so had to order a set up.

    A fair bit of tidying up of wires and hoses,also an earth wire was connected to the battery box ,I moved it to the rear head steady as I thought it would be a better earth.

    Top man... cracking on with the next job straight away... no 'standing on ceremony' !

    Who's valves and guides did you use?

    I fitted NOS to a T160 once, only to find out they had as much slop as the ones that I had removed assuming they were worn out !!

    I imagine modern parts supplied by LP Williams etc would not suffer the same?

    Funnily enough you're the second person to remark on that point! Guides and valves indeed came from LPW and after fitting the guides,the valves will not fit without reaming. All valves measured were a constant two and a half thou under, I should get the head back for the weekend with the three exhaust seats cut.

    You have been a busy boy yourself!! That 68'er has been shown some BIG love any summer events planned with it?

    My big challenge in life Jimmy is... knowing when to stop...!

    I bought a set of Morgo barrels, billet MAP pistons, 6mm stemmed Kibblewhite valves and conical springs etc for the Bonnie, even though it’s now ‘finished’!

    So... I managed to slap myself just in time... my plan now therefore is to leave the bloody thing alone, and all that kit on the shelf, and ride it !
