Dont get me wrong .. I have restored plenty of things myself .. some of them not so small either
so I am not averse to taking on a project. So happens my workshop is kitted out for some heavy tackle, and I know how much stuff that Ive had to spend in that workshop over many years to help me do my job.
I am wary for peeps in 'this' line of engineering however that if they take on a project .. sometimes its best left to people who have the 'work shop' because for those 'in the know' it all seems easy, but for the uninitiated theres a mountain to climb of knowledge and expense, and a lot of hard lessons learned along the way. It would be unfair to suggest that a repair of this type would be a walk over by any means, not that I said it was impossible, but having taken on plenty of projects over the years, the learning and
cash curve can be steep.
I dont mean to berate the op either, but if he's posting a question of this type clearly he is unsure of his costings, and that can only mean one thing, most be will higher than he thought, because in my experience few problems turn out to cost you less than you thought
and then theres the issue of useage .. maybe its just me .. but I live in a salt water environment where if your kit isnt up to the job, your going to have to rely on support which,.. the way things are looking up in the North of Scotland is going to become very scarce.
I've rescued my fair share of people who have been the victims of bad luck as much as silly mistakes, and others of plain stupidy
Up a river or estuary I would say no problem , but where the OP sails you gotta have some dependability, theres a big difference .. pessimist I might be .. and just an opinion, but I'm happy with it.
