Saving Old Seagulls

hi
i have a steel fuel tank and the two studs to fit it in its cradle need replacing and would like any opinions on my plans before i start, ( or indeed any better ideas)
what i thought i might do is cut off the old studs, drill two holes in ther place and cut m8 threads in the holes
then screw in 2 new studs cut from a lenght of stainless m8 threaded rod and solder them in place

Lot of effort..

How about phoning John and see if he has an replacement?

As a general rule - learnt from experience - I have found that it's better to replace rather than repair if possible.

i just hate to throw something out if i could fix it instead,
the rest of the tank is fine.
the other alternative may be to cut new threads onto the existing studs reducing them to m6.

charles, are there still plans afoot for a seagull gathering down your way?

You mention a cradle.Are you referring to a steel long range tank with a stud at either end or a standard steel tank with studs at the bottom that fix to the cylinder head lugs?
The studs on the standard tank are removeable.Those on the long range are not.What exactly is the problem with the studs?

Jothina - yes. As yet I haven't actually arranged anything. The start of the sailing season has me up to the teeth in race rosters, sailing policies and the like together with the ins6tallation of a radio based web displayed weather station, so I've bitten off a bit more than I can comfortably chew. Finished most of it though, won't be long!

its the long range tank, both threads were damaged and one stud has been bent somehow. i've just replaced both studs as described in my origonal post and i'm very happy with the end result. took about 30 mins to do , just wants a coat of paint to finish it off

Pleased to hear you've solved the problem.Sounds very much like one of my tanks.I made up a pair of shouldered nuts, which being longer, were able to screw onto the undamaged part of the threads nearer the tank.
