LOL wow this topic went to pot in no time , started with some good advice and some light hearted humour too boot... ended well.. badly.... i need to join in
At my advanced age and with my experience of materials and the command of the English Language, I am well qualified to pass comment on spurious comment.
With age dose not always mean more wisdom, ( i was going to add a comment about being senile but thought to harsh this morning you were lucky!!)
I have used vast amounts of the relatively new medium of MDF in marine envionments at 12 inch to the foot sealed with a variety of sealants, not including epoxy of any North, East, South or West Systems, without complaint from the end user.
not yet.. but im sure when the boat sinks you'll soon know about it....
As far as I am concerned, this post is now closed to my eyes.
is another way of saying bla bla i'm not listening any more (close minded)
but the Yorkshire anology remains
I have a one as well... ''sometimes you can't teach an old dog new trick's''
I was trying to be Sarcastic, so if you can't take a joke not my problem. Im sure Admin will delete the top bit anway
I wouldn't use mdf on a model at all, weight, quality are all issues you cannot guarantee for a marine use without the need to seal it using resins, if you say use ronseal exterior wood preserver/sealer im going to slap you... mdf is so tightly compacted it cannot absorb the sealer deeply enough with out literally submerging the whole lot and leaving it for a few hours, by which time its starting to come apart, swell and distort once dried.
Mdf great for indoor use, flat pack furnituer, and boat stands, used on a boat as skinning material .. uff taking a chance... LOL
And then it comes back to cost... to seal the mdf using epoxy you just added to the cost and weight, where as some one already pointed out you may as well buy some good quality ply and seal it the old fashioned way at less the cost & to better effect.
I use for many larger projects marine grade ply in either 2-3 or 4 mm thickness's pre treated, and ideal for the larger more bulky work where strength is also needed (bulkheads etc) I have used 8mm ply in my tug as hollow bulkheads, one for strength and the only to reduce how much extra ballast i put in when you have to load 30Lb of dead weight in then using some of the weight as reinforcement is not a bad idea, well i though so anyway.
