Yes, a beautiful clean, round hole and they really went through steel like it was ally. Strangely, towards the end of the job one of the steps (16mm) just stopped cutting, the drill just span and heated up. I cannot see any damage at all, but it just does not cut any more. Very odd.
I only have one, an eBay job made of Chinesium. It cut great until the first step went blunt - it's been resharpened [mate did it while I was busy with something else] but has yet to be tried in anger....
Handy for those 'quick' holes, but I've never measured the degree of accuracy it provides.
Hi, You could extend the locker all the way to the mudguard and just have an removable panel to access the shackle pin or slightly bigger to be able to unbolt the hanger bracket. I would keep the fuel tank covered to avoid extremes of temperature to stop the tank 'sweating' and causing too much condensation internally.
I think the ground clearance is fine - it's way above the stated minimum and about the same as our horse truck which had much longer wheelbase.
The fuel tank could move forward into the front locker. That locker is an awkward shape anyway to clear the brake servo but the tank might sit front of that (I haven't checked yet) Lowering the tank to the locker level and moving slightly away from the centre-line would make it easier to fill; it's awkward at the moment being too close to the deck. That would free up a whole lot of locker space in the centre.
HA!...yeah, but its a really nice shower tray!....maybe to satisfy the hot rod urge, cut some no slip material for the floor in the shape of flames.
As for the tank, I wondered how you were going to get fuel into it when I first saw the pics, so moving it forward and down would solve a lot of "I should have" regrets later. moving it forward and down, with an emphasis on forward, would also keep it just that much more out of harms way for clearance issues with the ground....(though it sounds like you will be fine anyway)
