Title: Re: Q & A - GLYNN GUEST plan, for the beginner, how to print?
Post by: RaaArtyGunner on June 30, 2011, 11:09:38 AM
What happens if I click on the print button at the end of John's excellent Vosper build.  :-)) :-)) O0 O0

Will it just print all the text,  {:-{

Or text and images.

If not, how do I print out the build sequences as set out by John, with corresponding photos.

Hello

Many thanks for a really helpful article.

I have just started this build myself (it will be my first) so the masterclass could not have come at a better time.

Cheers

Hello folks
Does anyone think it may be feasible to use 2mm liteply to sheet the hull sides rather than balsa, any advice critical or otherwise woeld be appreciated.
Thanks all the best,John
Title: Re: Q & A - GLYNN GUEST plan, for the beginner
Post by: John W E on September 25, 2011, 09:42:23 AM
hello there,

yes, it will be quite feasible to build this model in 2mm lite ply.   I think the points to look out for would be:

You would have to build the keel up with several layers of lite ply to get the correct thickness, say 3-4 layers.

Also, you may have to double up on one or two of the ribs to make them a little thicker.

Using lite ply for the skin and decks plus bridge would be okay.

I am just about to complete the model of Virgin Atlantic Challenger which is supposed to built using balsa wood.    I opted to use lite ply in its construction.   This has turned out okay.

Just thinking about though, the advantage of lite ply over balsa for skinning is that I was able to use a 2 part finishing epoxy on the lite ply for  the Atlantic Challenger and sand away to me hearts content to obtain the finish on the hull that I wanted without fear of cutting into the timber.   Whereas, if you use the tissue/dope method you have to get this on the hull pretty smooth to begin with and you have to be more precise rather than haphazardous like me.

Hello John
Thanks for your reply and advice I will have a go at using liteply for skinning the hull ans also the decks and bridge, but I will stick with balsa for the framework, and follow your excellent buid article in conjunction with the model boats article, I am a relative newcomer to building model boats although I have a bit of experience in building and flying radio controlled model planes from some years ago using these materials, and lI to can be a wee bit heavy handed when it comes to the finer arts of sanding balsa and trying to seal it, and I like your idea of the two part epoxy finish to prepare for painting. I think your build of the Atlantic Challenger look gret and has helped convince me to try the liteply method,
Thanks all the best, John.

Hi

I have just joined the forum. Have started building the Glynn Guest Vosper and needed some more help, after seeing this I have had all my questions solved. What a great piece of work and very helpful.

I have had the plans enlarged from A1 size to A0 size making the boat just over 36" and making it a about a 1/24th scale. Some challenges but now seeing this will help me even more. I have already made a lot of the details parts even the cowls myself, now just assembling the hull.

Great site and thanks again

hi all glad the build is of some assistance - it was an enjoyable build.   I have noticed though that there are 2-3 pics missing at the end of the completed model.   An oversight by Our Leader when I kindly asked him to watermark the photographs.  So, here are a few pics of the finished model.....

Post by: vernon on April 03, 2012, 01:58:16 PM
Thanks for the info. Obtained a copy no problem. In trying to kit out a set of parts following Glynn's comments I do not seem to be able to get either the Graupner 451/1 propeller or a 267mm prop tube.
I have tried Graupner website and although they list the 450 and 452, I cannot find any reference to the 451. Glynn's comments on the running performance related to this particular prop seems to indicate the need for a 30mm 2 blade prop.
The only prop tubes I can find are 254 or 280mm versions. I realise that i could adapt the 280mm but as a first model for some years I am trying to make it an easy start.

Can anyone throw any light on the subject or offer alternatives.

Post by: John W E on April 03, 2012, 02:25:02 PM
Hi vernon
can i ask which method of motor installation you are going to use - is it the one that Glyn used in his build using a solid coupling or are you going to use a flexible coupling as in the build I did ?

 

aye

Thanks for replying. I have just started to read through the build notes outlined on this site and see the alternative mounting which I presume allows for the use of a 227mm prop shaft using a flex coupling which is what I will use. It also uses a 3 blade 35mm prop. Is there any particular type as I presume the pitch is critical. I was planning to use a 545 motor.

Post by: John W E on April 03, 2012, 06:39:03 PM

Hi there, what I did was go down to the lake with a few props (I purchased some props of various diameters from Cornwall Models ) they were all 2 blade racing props - Trial and error to get the performance worked for me.   The one I used and got the best performance from was a 2 blade 32mm diameter prop.  The 3 blade prop which you can see in the picture of the build was one of the 'testers'.     Here's the link - I think it would be good for you to do a trial test as well to see which is best for your motor/model.

Hi folks,
  Just joined this site as I need some help.  Have a Glyn Guest plan for a PT boat, Model Boats 1999.  I have cut the deck, bulkheads, etc.  The plan is not very accurate, but never mind.  I am looking for a supplier of the shaft, propellor and gears.  No hobby shop in South Africa is able to help.  The clubs keep everything secret.  Can anybody help me out here.  Will pay for the items.

Thanks bluebird,
  I will give those guys a try.  Just a correction, I did not mean that Glynn's plans were inaccurate, I think it was the printers etc. that got it wrong.  Who knows, I might start posting my buils of the PT boat here.

Hi

I have recently got hold of the plans for this - planning to build one over the winter, and try to "up-scale" it a bit...

Had an idea of diagonal planking the hull (ie as per the original construction method), using coffee stirrers or similar (with tissue or glass cloth covering) rather than simply sheeting with balsa...

Would this work do you think?

Post by: John W E on August 07, 2015, 06:29:48 PM
Hi ya David

May I ask you to err on the side of caution; as when increasing the size of models from Plans and altering the builds; you can run into all sorts of problems.   Maybe not so many problems for an experienced builder, but for a person who is relatively new to the hobby - personally I would advise you to build this model as it (straight from the Plans) and this would enable you to see how the model goes together, how you actually fit up the power drive chain and so forth.   Whereas what you are asking to do - which is quite possible to do - you can start to run into problems.

When you start to diagonally plank like you want to do and also increase the size of the model - you will have to begin to think about putting extra support in - e.g. stringers on the sides and on the bottom - these are strips of wood to support the diagonal planking in the middle of the planks.

Basically this design for this model doesn't lend itself too readily for doing this. So that is why my suggestion is to stick to the plan size for the model and minimise the problems that you are going to create for yourself.

If you are really into this type of style of model - the Marine Modelling International Magazine (last month) did a free plan for an RAF Rescue Launch which I believe Stavro is building.   This is an actual twin motor model and it looks a very interesting build but built of a similar style as Glyn Guest.   Also a while back the same magazine did a free plan for a Vosper MTB semi-scale and this one is the same as the Airfix MTB is.

When you have built your skills up; you then possibly may go on to building from plans such as Vic Smeed's plans/John Pritchard's plans.     Have a look at MyHobbiesStore at the style of plans and also have a look at the MasterClass build and you will see an Air Sea Rescue Launch which I built and diagonally planked.   Also if you do a search you will come across the RTTL which I built.   This is also diagonally planked.

Hope I haven't put you off too much and dampened your spirits but good luck with what you choose.

Last but not least, going back to the Glyn Guest MTB; you can really add a lot of detail to this model and make it look something really nice.  Do a web earch on the MTB  :-))

Hi
 
Thanks for the info - think I misled you a bit - by "up-scale" I meant detailing it up from semi scale...rather than making it bigger!  Think I got my terminology confused...
 
I wanted to use a build log I found of the Italeri MTB77 plastic kit as further detail to try and add a bit more realism - adding deck tools, fitting out the bridge etc.  The plans you've highlighted also look really good
 
Do you think the diagonal planking would work on the basic hull frame (keel, chine-floor and deck) at the planned size (26" I think?) I guess the plank span from keel to chine would be c3 inches?
 
Don't want to bite off more than I can chew, but also keen to try new things!
 
BTW - I've just started going through your build log of the 63ft whaleback ASR - Its such a beautiful design, and they way you've built it is really inspiring me to try the same one day...!  Only thing is that it seems such a shame to cover up the planking!

I once saw a ply sided hull scored or pencil marked hull stained and grained to look like planking.Very clever  John Mantova
