SG&K Gentleman's Runabout
« on: October 07, 2012, 01:01:01 pm »

Just purchased Traplets 'Laser Wood Pack' semi-kit & plans for the SG&K Gentleman's Runabout boat.


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.

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 {:-{

Progress so far:


Start of frame work, green cutting mat comes in useful keeping frames square to keel while positioning and glue frames one at a time.

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.




More rubber bands and clamps.


More pics to follow shortly.

Problem with boat frame, gap occurs when building frame see pics



Spindrifter found this on his build as well.


Easily corrected by filling gap (both sides)  with scrapes of wood.


More pics of finished frame:




Note GAP on 5th frame up.








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 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.

Rudder Cut out and fitted

Scratch built rudder from copper plate and steel shaft glued and pinned...... This version bent and broke when when I tried to straighten it after I drop the the boat  <:(

Bass wood strips (approximately 10 mm wide)



I coated wood with cellulose sanding sealer then glass resin applied internally in stages.



Starting to take shape and look like a boat hull.



Start of Motor mounting

 



Mounting for motor. 2 wood blocks drilled thro' to suit bolts then ct'r sunk at back to fit hex nuts. (Note made holes for nuts same measurement as nut size measured across the flats, then glued and pressed the nuts into wood to make them secure)

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.................

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

More pic's


Decided not to modify prop shaft as motor and prop shaft came as a complete unit. So next best alternative as shown.




Servo requires cut out in frame.



Servo assembly secured in place



All hull sides complete. (Balsa wood 2.5/3 mm thick)



Sand and filler then sand sealer coated. Then sanded again...etc.



Next.... My first attempt of fiber glassing a complete hull... :embarrassed:

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?
