Title: Hull plug
Post by: Odd Job on February 26, 2013, 08:31:49 pm

Hi Guys
Newby to this forum, I am returning to the hobby after some 18 years.......whoa how things have moved on!! no more Alley Palley or Maritime Models....those were the days & now you have better electronics & a new frequency. If I said I was running 27 megs on splits & 40 megs had just come in, it shows my age a bit. Anyway enough of this ....... I am looking for some guidance?ideas on how to add plating details to a plug so that I can produce a fibreglass mould. i.e if I add plate & rivet details I will not be able to sand the surface to give  a smooth finish. Any ideas would be appreciated

Welcome back to the hobby  :-))
Two ways I have been told about but never done any moulding so can't say for sure are
1) litho plate glued onto the hull
Or
2) brown paper glued on.


The litho plate I have seen and it looked pretty good and it gives a good finish
To the plug

Similar to litho plate is the self adhesive Aluminininium duct sealing tape.

Odd Job,
Bryan Young, whose models you'll see under the Master Build section, uses card fixed with double-sided tape. I have done likewise and also used an impact adhesive where tape didn't seem to be sufficient. I obtained card in sheets from Stationery Box and this has a semi-gloss smooth surface needing no preparation other than the usual wax spray before laying up.
Should you struggle to get the plug from the mould, you may find that some of the card plates will get left behind on the latter but these are readily removed by a good soaking and leave a smooth surface.
Good luck.
Barry M

Thanks for that all of you, I have used the brown gummed paper method in the past but only on static models destined for a glass case. I have considered the Litho plate method but not sure where to locate the materials any suggestions?
Cheers

Have a look at the "Plating" on the plug of this hull :- http://www.modelboatmayhem.co.uk/forum/index.php?topic=16238.msg216005#msg216005 (http://www.modelboatmayhem.co.uk/forum/index.php?topic=16238.msg216005#msg216005)

Aluminium drinks cans are as good as Litho plate, cheaper and I always enjoy emptying them.
