Alloy tank

[timk]

I am finally restarting the build of my Triumph Greeves in a 59 Hawkstone frame I am a great MCC trials enthusiast and I dont think the standard Hawkstone alloy tank has enough capacity for all night in Devon and Cornwall so I would like to find something bigger but in keeping . ideas and offers welcome

The 1959 Hawkstone had a (1 3/4 gallon I think) STEEL tank not alloy. It should be possible to fit a roadster 2 1/2 gallon tank on for long distance trials

My Grumph has this tank on it, although I have thought about a bigger tank that I have. What part of Devon are you in? I am near Crediton.

I am a long way from Devon in Bedfordshire my reference to Devon was the Lands End Trial that I want.
What tank is that? I have seen references to a Triumph Trailblazer tank and a G2 Matchless tank (a bit heavy)

You may find you need to add lockstops if you are using a trials frame/forks as forks will hit tank. I drilled and tapped 1/4 bsf on the forks the same as roadster forks to get over the problem. Just thought you need to check before painting!

Good point about the lock-stops, John. Ideally, an ISDT tank would be the answer. I have no doubt Greeves factored that in to the shape of the tank. Hard to find though these days, no doubt.

Thanks for the pointers

Here is pic of one of the LHK 1958 ISDT bikes, there does not look any dents in tank to clear the forks, so must have had suitable lock stops.
