Just purchased Traplets 'Laser Wood Pack' semi-kit & plans for the SG&K Gentleman's Runabout boat.
(http://s16.postimage.org/5bel6a0wh/SG_K_s_Classic_wooden_boat.jpg) (http://postimage.org/image/5bel6a0wh/)
For ref: http://www.trapletshop.com/gb/p/13862/sgk-gentlemans-runabout-wood-pack-plan
Tried to do some research on this boat but not much on the web.
Can any one help / advise:- Has any body attempted this boat build?
- What does SG&k stand for?
Thanks John

Please do a build log John!
I've always had a slight fancy for this model myself.
-
HI Roker, the build is featured in Int. Marine Modelling May 2011.
regards Roy

Hi Roker and welcome to Mayhem.
I would be interested in a build log as well. Please post as many pictures as you want. :-))

Plans & Wood Pack Arrived at last...
Now I'm in a quandary, also just received a CHRIS-CRAFT BARREL BACK KIT which I won on e-bay auction.
Now which one do build first?
The SG&K runabout wood pack only comes with the laser cut frames, so more wood to purchase?
The Chris-Craft comes complete with every thing, but looks like a long project.
Also still busy finishing a "ORCA" boat (The boat out Jaws).... So It will some time before I post back {:-{

Hi rocker,l have just finnished the gentlemans runabout and have 90 odd photos of the build,mine is planked in mahogany.spindrift.
-
Oooo, Spindrift, that's super :-))
-
Just got round to starting my SG&K runabout. So log of build will follow shortly.
Looks like Spindrifter set the bar high on this project, fantastic pics of his boat...... :o
Well done Spindrifter how does it perform on the water?

Pictures of build.....
{:-{ Whats happening guys..... Will not up load images. (looks it's trying to upload... finishes then a flash message 'redirect' shows... then crashes out?). Will try later <:(

Progress so far:
(http://i216.photobucket.com/albums/cc66/yellow_jr_photos/SG%20and%20K%20Boat%20Buld/Build2.jpg)
Start of frame work, green cutting mat comes in useful keeping frames square to keel while positioning and glue frames one at a time.
(http://i216.photobucket.com/albums/cc66/yellow_jr_photos/SG%20and%20K%20Boat%20Buld/Build4.jpg)
I started with the middle frames and worked out over. Note a couple of square heavy metal blocks came in handy keeping frames in position.
The 1/8" square ribs came next. Fitting & gluing central aft, fore deck and hatch straight ribs first (elastic bands came in handy for keeping ribs in place). Doubled check frames and ribs making sure no twisting of frame / keel occurs letting glue dry completely before attempting outer aft & fore deck ribs.

Problem with boat frame, gap occurs when building frame see pics
(http://i216.photobucket.com/albums/cc66/yellow_jr_photos/SG%20and%20K%20Boat%20Buld/FinishedFrame1-1.jpg)
Spindrifter found this on his build as well.
Easily corrected by filling gap (both sides) with scrapes of wood.
More pics of finished frame:

Order a Robbe Navy Power Set type motor which include the Motor / gear box, prop shaft & propeller complete.
Motor arrived today but >>:-( wrong motor assembly was actually delivered.
No fault of the supplier, but Robbe some had manged some how put the totally wrong motor in a wrong box with correct ref/part no I had ordered.
:-)) to Westbourne models who are sending me the correct motor asp.

Hi Rocker,have looked at the progress of your SG&K,problems are exactly the same as l had said.
It now that the slot for the rudder should be cut.
Keep scratching.

Hi Roker, I've just ordered the plans and wood kit - can't wait. The Traplet site dosn't seem to give much information about the plans - what length/scale is the boat? After seeing Spindrifts model, I can't decide how to finish the hull ( :police: when the plan arrives!!).
I'll also put some images up once I've started to build - might even finish this one ;) !
-
Hi hale21,length is about 33 inch scale is 1/8 th.Beware the the gaps you will find in the frame,s,(both rocker and myself found this).
You will also find the measurements differ between the drawings.
If you need help l have 80 odd photo,s l can either send to you on disc,( if we can come to an arrangement),or l can post them on mayhem a few at a time as you need them.
Clive.
You can keep scratching but the itch is there forever. :-)) :-)) 8)

Many thanks Clive,
Brilliant - I have a plan to build a trailer for a stand and have some original Series 1 Land Rover drawings. This was supposed to be a quick build!!
I'll be camped out by the letter box waiting for the plans!
Thanks for the offer of your photos, let me know the best way get them.

Looks an interesting o-ring sealing on the rudder shaft there Roker....... :-)) ......................but I am a little confused on how it is installed?......
Is the disk with the collar & o-ring tapped & screw's down & locate in the hull proper?..............Derek
-
Derek,
The rudder mounting is a one piece of turned brass with small collar at base, threaded externally with a thro' hole to suit rudder shaft.
The o-ring is then fitted before assembly to hull and a large washer & nut keeps it secure.
(Note I did not make the rudder mounting but salvaged it from and old boat but added a o-ring to make good seal.)
Hope this helps.

Plans didn't arrive in time for the weekend - so with help about scale from Spindrift, I made a gearshift. I still have to make the sides (and get a better camera) and I think the lever handle is a little too long. I'm planing to connect the gear lever to a servo linked to the speed controller - is this possible?
Stop Press! Plans and wood pack have arrived - now where's my glue!!
P.S. Dear Santa, please can I have a lathe, a milling machine, a nickel plate bath, a laser cutter and.................
-
I'm planing to connect the gear lever to a servo linked to the speed controller - is this possible?
Absolutely.... just use a Y lead from the Throttle channel to the ESC and Servo.... A sub micro servo like this one should be more than adequate
http://www.servoshop.co.uk/index.php?pid=XYMS37SS&area=Servo
you might even get away with a micro linear servo if you want to keep the weight down
http://www.servoshop.co.uk/index.php?pid=JP4499958&area=Servo
The hardest part will be getting the throws between the servo and the shifter to match. Not exactly difficult just a bit of a head scratcher

Here we go! Bought some wood for stringers, found my glue, threw it away, bought some more and now fired up for the Christmas break!!
Also couldn't resist, bought a JP EnErG 550 brushless motor - I have know idea what to do with it but it looks great :-)) . Any advice would be appreciated.
With so many build going on, sounds like we should have a regatta in 2013 (Roker hope you don't mind me gate crashing your thread)!! :kiss:
Clive did you get my email?

of disc postage and packing l will send you my photos.
Call me on 07570053 HFC.

Boat worked great on the pond.
My final comments, great boat to build, my first plank on frame (made some mistakes on the way but don’t we all), special thanks to Clive for supplying his pictures.
If you want any further information on build / materials etc drop me a line. More than happy to help.

What figure did you use? he certainly looks the part!

Somehow missed this completely - bonus is I got to read it in one go. Nice build :-))

I
want need one of these.... must resist tho, too many others on the shelf!

Just super glued my thumb and finger together attempting diagonal planking around the stern! This time it really stuck - missing skin on thumb. I think it might be time to start steaming the planks, or maybe try using contact adhesive - any suggestions?
Getting quite close to finishing - photos to come.
-
One suggestion might be to get a bottle of Super glue remover. Hope you're allright.
Ken

And maybe put it handy and crack the seal - before the glue work begins O0

I knew there was something else I meant to buy!
Fingers free and I think I've solved planking the stern :-)) !

Hi all,
Here are my latest build photos:
I've added a a dummy engine, the brushless motor fits in front and underneath, re-modelled the dash (more work to be done) and made one of the seats.
You can see the problems I had planking around the stern (well done spindrift!). Does anyone know of a good mahogany filler or is it sawdust and glue?
After reading the build write up in Marine Modeller International I've decided to fit trim tabs, you can see the control tube on the port stern. Also I made a dummy fuel filler, which is my shaft oiler.
Still loads to do - started thinking about my next build!

I just discovered this thread and registered for the forum. I am the designer of this boat. The boat was designed as a full scale boat, the design was then reduced to make a model. The first model was a 1/4 scale "proof of concept" boat. The design was then drawn as an 1/8th scale boat, Bryant Thompson built the model and wrote an article on it. SG&K Classic Boats is now Stillwater Boat Company. The boat builder/restorer is Steven Gray. Steven is a retired US Army helicopter pilot. The forward part of the hull was lifted from the 1952 Chris Craft 19' Racing Runabout, the aft portion of the boat si all new classic design. The design has undergone some changes. The Chris Craft has very little freeboard, therefore it is a rather wet boat. The original bottom design is very much "old school" flat bottom. That makes for a faster boat when there is limited power available. The flat bottom design makes for a rough riding boat. The freeboard has been increased and the bottom is now a "Vee" with 22 degrees of deadrise. Full scale CAD plans are available as .pdf files for the 1/4 scale boat.
I have several other model boat designs available in scales from 1/8th to 1/2 scale. The 1/2 scale is of a 21' Chris Craft Cobra.

Hi Quickshift
I enjoyed building the run about very much,
and l hope l have done it some justice.
I have a couple of questions if l may.
Did the full size boat get built,and how many blades
on the propeller.
All yours
Clive
Richardson
(Spindrift).

Clive,
The full scale boat has not been built, we need to hit the lottery or find a buyer to order one. The boat builder has built a 1/4 scale boat. It has a gas engine with onboard starter. We used the 1/4 scale model to verify the water line location. The full scale boat would most likely carry a 5.7 liter GM V8 engine. I would guess we hould carry a 4 blade prop on that engine. My 30' boats are dwsigned for twin V8 engines. They can carry twin V10 Ilmor engines. If the front cockpit is eliminated on the Great Lakes Racer she can carry 3 engines as large as 700 HP V10 Ilmors. At 2100 HP the boat would not be the thing for the uninitiated. It would definitely be capable of rapidily getting into more trouble than the driver could handle.
Pat
