At last......

Well I managed to cut a hole in the front bulkhead after nearly a day at it. The 9" grinder (when used right) made light work of the sides in comparison to the top which was attacked with a 4" grinder Which was a little more time consuming. The worst part was the L bar strut which provides strength to the bulkhead, which took ages to hack through with a junior hacksaw (wasn't a lot of space). But at least it's done and now can use the stairs I made to access below deck. Just another bulkhead to cut (to the aft cabin) and the bit of metal that I keep banging my head on midway down the stairs.
