Hi Rangie,
Good to see another thorough Tiger build - must get back to mine...
You will love those wing nuts - expensive but worth it. They certainly finish off the jack mounts.
On the topic of the front hatches this took me a while to work out. The metal hatches fit very snuggly into the tabs underneath the hull but for some reason they don't open quite enough to swing past the vertical when open.
They should look like this:

I did cut out a notch in the lip of the hatch ring (not strictly accurate as you can see) but this didn't have the desired effect.
The simple answer turned out to be this: just sand down the mount so that it's about half the thickness and then fit it back in place. Since this means that the hatch is now raised up slightly it just allows it to open a little wider. This should keep it from moving about as well...
