i hope you didnt cut the mast
that would really put you in a liable situation if it was to break and hurt some1 in the future

you could remove the mast at the trunnions but then you would need a crane to get it back on once inside

i have other ideas but theyre risky and dangerous (as is removing the mast)

i see this was a while ago i hope youre still not checking every 5 - 10 minutes lol
