16. Finalising tank mounting...

Finalising tank mounting...
Rear mounting...
Tank is rubber mounted... preferable on Harleys due to coarse vibration. Rear mount is to be filled with silicone into which the tank will wedge. This sheet metal cover buts up to rear of tank and once moulding is complete the join will be a fine line...

Rear of sheet metal follows line of seat padding...

Front mounting...
This is a reinforcing bar "spot" welded to tank front to spread tension of front mount and prevent cracking. Notice how bolt is slightly canted to rear. This is done so that as bolt is tightened, it will push tank into rear mount and hopefully be nice and firm...,
Image

Front of tank mounting is cut on an angle so it doessn't foul moulding as tank is attached
Image

A bit of that Hills tube is cut to fit on frame at front of tank. Curves on left fit into steering head and angle on right matches the angle on the front of the tank mounting...
Image

Tubing welded on. Once moulded, tank and frame will be separated by a fine line.

Rats a dent...
Tank must have been dropped by sandblasters cos it came back with a small but deep dent.Piece of 1" x1/8" bar is welded to centre of dent and the dent pulled out using a slide hammer...
Image

Slide hammer is home made... centre is 1/2" round bar with a nut welded to one end and a piece of flat bar with a welded bolt at the other. Slide is made of two pieces of water pipe and a small tube hammered inside each other and welded. Works a treat...

Tank now ready to mould...
...and for your interest... an easy way to hold things you are welding... like the bracket above... is a swivelling piece of aluminium angle (horizontal bit)mounted on the wall above welding bench, a piece of dowel (the vertical bit) and a couple of welding clamps... Yes, I dropped tank while moulding and got another dent!
