[LARRY WHETTONParticipant @larrywhetton68737]

Goog morning ,

Thats the idea , i did the same . but i used T section styrene, on a tug ……

Guardsman. coming on pictures soon……….cheers Larry…..

[Bob Abell 2Participant @bobabell2]

Thanks Larry…..Good idea!

The card gussets were too fiddly!……..Used your idea eventually and made them from plastic "T" section………Solid brass of course!

Bob

[LARRY WHETTONParticipant @larrywhetton68737]

Hi Bob ,

Glad to help………..they look good ,

by the way tell that winch man to get behind the winch all he become chain fodder,

sorry ex elf and safety……..

GUARDSMAN ready to launch , when the weather gets better …..….Larry…

[Bob Abell 2Participant @bobabell2]

Thank you, Larry

Latest WIP report on the Glasgow build.

Not much done lately, due to the gloomy weather. The top deck needs to have a bonding coat of Matt varnish, to blend in the gusset additions etc, but the latest cold weather has put paid to that, at the moment.

The motor chain drive needs speeding up, having seen a Glasgow drifting about the club pond with no sign of paddle wash!

Bob

[Colin BishopModerator @colinbishop34627]

Don't speed it up too far Bob otherwise it will look like a duck taking off!

I have seen Glasgows with plenty of paddle wash.

Good Morning Captain Bob

Sounds like a job for a huge brushless motor!

Paul

I wonder how fast a paddle boat with a displacement hull would actually go?

If you used a catamaran type hull with a central paddle wheel between the sponsons not only would the wheel provide drive it would also compress the air between the hulls and create lift…..hm and idea for Ashley to play with.

Well, now you mention it….what an idea!! hhmmmm….

I am sure I have seen on u-toob a clkip "fastest paddle ship" or something, a stern wheeler going improbably fast (model of course)

A paddle ship is on the list of "to do`s" somewhere. I was going eventually to make HMS terrible, a paddle warship, eventually.

Ashley

[Bob Abell 2Participant @bobabell2]

Thanks chaps for your excellent advice, but the paddlewheel speed is far too slow at the moment

As you say, too fast is not adviseabell, but I saw a comment on a mill paddlewheel article recently, which had aerated floats and the "system was much improved"!

Sounds very interesting?

Bob

[Bob Abell 2Participant @bobabell2]

Finally got the chain drive sorted!

Actually, I needn`t have bothered!……..The reason for the slow speed, was that I was using a 6v supply instead of 12v!

Time for a bath test now and see what`s what!

Bob

[Bob Abell 2Participant @bobabell2]

The Bath Test chaps!

I was surprised how big the model looked in the bath!

The model is very balance sensitive about the longitudinal axis and with a few quick bursts of the paddlewheels, she almost rolls over! Probably caused by one paddlewheel doing all the driving in a slight tilt……….Steady as she goes, on the first pond trip, eh?

She needed about 2 lb at the front….or about half a bottle of Dettol and a bottle of hand cream to be more precise! More ballast may be required later, as it was difficult to see the waterline

The Becker rudder worked well, but the tendency to roll over is a bit of a concern.

A keel type weight may be a good idea, for stability, similar to Great Eastern, where the ballast can be adjusted easily

A floating safety buoy on deck, with a length of rope may be adviseable……In case she goes under?

Bob

[LARRY WHETTONParticipant @larrywhetton68737]

Hello Bob,

paddler is looking good, do think the yawling may be a fortex caused by the shallow water ,

wizzing round bath sides , ..?…

or when a proper pool test , do think a twin motor drive would be better,

Iam looking at tank drive motors and gaer boxes for lagonda, now have some part built paddles

in brass , looking forward to your sail……..cheers Larrry..

[Bob Abell 2Participant @bobabell2]

Thank you, Larry

You have raised a few good questions there!

Shallow water could be a good suggestion

I`ll make the model more secure and try it out at the pond shortly

Bob

[John ShireParticipant @johnshire55937]

Bob

Are you going to do a static pull test to see how powerful your boat is?

John

[Bob Abell 2Participant @bobabell2]

Don`t think so John…….

It`s only a 540 motor and gearbox

Bob

[Paul TParticipant @pault84577]

Bob

To take Johns idea a little further perhaps you could recreate a famous event.

HMS Rattler pulled HMS ????? all over the bay, But what was the name of the poor paddle ship?

Paul

[Bob Abell 2Participant @bobabell2]

Thank you Paul and John

I've often reproduced the famous sea trial myself……..Paddle v Screw on Great Eastern and every time the big paddlewheels overcame the screw!

How do we decided what size of screw and paddle are a fair contest?

I remember the Wankel powered John Player Norton sweeping the board a few years ago over the normal engine powered bikes

It got banned soon after when they changed the capacity calculations!

Perhaps, this summer, our club could carry out a few similar tests…….but what is a fair test?

With big props, little props, big paddles, little paddles………Tricky?

Same size motors would be a good start

Bob

[Paul TParticipant @pault84577]

Bob

Same size and shape of hull and same size engines with the test carried out on a flat calm lake having no undertow or current.

Paul

[Phil Winks 1Participant @philwinks1]

Surely Bob the GE has both paddle and prop so thats definately an unfair advantage lol

Phil

[Bob Abell 2Participant @bobabell2]

Hello there, Wee Willie Winkie!……..Too true!

How about a tug of war, with five boats aside………As a show stopper?

All the best……Bob

[Chris HardingParticipant @chrisharding83544]

Bob,

I am new to this forum but have been modelling model boats, and trains for many years. many thanks for your build log, it has given me some ideas about the Glasgow kit I have ordered, and which should be back in stock next month. I was originally going to convert this boat to either the PT Lingdale or PT John. H. Amos. I am still leaning towards the Lingdale but your exellant build log has got me thinking (that is the ex RN matelot in me coming out). Keep up the good work, much appreciated.

Chris

[Bob Abell 2Participant @bobabell2]

Thanks a lot, Chris

Your kind comments are much appreciated

Bob

[Bob Abell 2Participant @bobabell2]

Right then…..What`s this chaps?

Could it be a hatch?

Yes!…….But more than that!

We give up!……..What is it then?

When a heavy plastic model gets rammed……….It often goes to the bottom!

All is not lost though!

Up pops the Wreck Marker!

Hopefully…………Bob

[John HuttonParticipant @johnhutton73485]

Hi again Bob,

My attempt at a Glasgow build is now almost complete. I’m waiting for some “T” section to arrive for the rail stanchions and I will paint the waterline when I have checked it. I have been so busy building yachts for other people that I haven’t had the time to do anything other than a straight build. I will however rework the paddle boxes later as they don’t look anywhere near as good as yours. I wish I had your patience and attention to detail.

I fitted the recommended motor and gearbox which, with the 12v battery, are very heavy so I don’t think I will need any extra ballast. I’m very impressed by the epicyclic type gear box. It is a neat little assembly which will allow me to change ratios if I haven’t enough paddle speed.

I hope to do a sea trial early next month. I will let you know what happens……..wish I had fitted your wreck marker…………..

John H

[Bob Abell 2Participant @bobabell2]

Thank you, John

You've made a nice job of your model……..Staight out of the box!

I note you have omitted the bulwark gussets till last?……. They are very awkward to fit at this stage,due to the tricky painting job!

The waterline should be as drawn and you balance the boat accordingly?

I recco an external floating lifeline on deck…..You never know!

Bob

[Bob Abell 2Participant @bobabell2]

Hello Stuart Alexander

Thank you for your PM

The chain sprockets and chain can be purchased from HOBBY`S Ltd….. **LINK**

but you will need the use a lathe to convert the sprocket hubs

Regards Bob
