Hello
I bought an old swordsman from a friend recently and have started to refurbish it This will be my first foray into refurbishing wood models so I think I will learn a lot!
It was a gas-powered boat but this will change to electric.
So far, I have sanded the paint back to the wood and have filled the bow section damage.
I have found an area around the hole for the prop shaft that has delaminated and come away from the keel.
My plan is I am going to use Zap ultra-thin penetrating CA to re laminate the ply sheet. then use cascamite glue to reseal all the joints around the hull.
Would this be a good way to repair this damage or is there a better way?
I will keep this thread up dated with new photos and progress reports over the coming weeks.

Richard

i am going to use Zap penit

Hi Richard
Whilst the delamination appears local chance are the fuel has penetrated well into the laminates together with water. Use whatever you want to patch the damage but a fresh piece of ply will probably be cheaper and more resilient. Cascamite will not work well with cyano.
I would, after sorting the damage, use a thin resin poured and swilled around the hull insides to seal, followed by a covering of glass fibre or cloth over the outside impregnated with polyester lay up resin. You can fill any resulting blemishes with car body filler.
As the model had an ic engine chances are the prop shaft will be showing signs of its age. Even if the bearings appear ok'ish the shaft is most likely bent or twisted. I suggest whilst you are sorting out the delamination you purchase a new unit of the same size. Most modern kit is metric so your shaft should fit any props and couplings you purchase. Some use an allen key to secure the coupling so this may not apply. Don't forget to fix a locknut and thrust washer at either end of the prop tube.
If you look at the blogs on this site there are several example of how others have completed similar tasks
Hope this helps
Please keep asking if you need any further help
Dave

Superb advice from Dave M, just a point the boat you have is not a Swordsman but a Huntsman, good luck with the renovation

I have both huntsman and swordsman, and visually there is no difference. I have been to many boat yards over the last 50 years and seen both of the real boats, and both can have open tear cockpit or rear cabin. The differences lay within. Nice model and I concur with replacing the delaminated section. I use fine glass cloth coated with water based resin to cover my hulls.(eezicoat) No smells so handy when working in the house and dry in about 25 mins.

hello
I thought the difference between the huntsman and the swordsman is the huntsman has a straighter bow than the swordsman?
it is confusing that you can have either in either configuration!

Go to the fairey owners club site, some great info and pictures. Also look up historic racing boats. You'll be pleasantly surprised by what's out there. Some boat yards have some nice examples for sale and the pictures are good for reference.

The differences also relate to the length as well

Ill put my money on it being a huntsman 31, probably modelled by precedent. I dont know of any models of the Swordsman with aft cabin, it might just help when sourcing parts, fittings etc

Hi good news, I have just checked the area of damage around the shaft exit, on further investigation there is no delamination👍 i think I will re stick the ply sheet down then stregthen the area with modeling tissue and resin. i am fotunate that the wood strips that run from the bow to the stern (i think they give the model grip and straight line stability,help i do not know the correct term), give a natural line to patch upto.i will stengthen the interior with wood strips again resind in.

I have purchased a new prop shaft as suggested by Dave M. i am going to insert thrust roler bearings each end adjusted up so there is no slack. i will let you know how it goes.

Richard - good to see you giving the old girl a new lease of life. I agree that it looks like a Precedent Huntsman 31 with the model being 46.5 inches long.
I have one as well.

There are differences in hull design between the various full size models which would be difficult to differentiate between in the models but none of the Swordsman have a full height rear cabin, only partial height and no windows.

The Super Swordsman does have a full height rear cabin, like the Huntsman, but the SS has much longer air vents/cowls on the sides. I have never seen a kit or plans for the SS.

I'm actually going to start building a Swordsman 33 soon and am in the process of drawing up the plans.

Hi Richard - the SS does have a front window.

Just found out as well that some of the Swordsman have the longer air vents like the SS. Missed this previously as all the models I've seen have the smaller vents.

I think I've got all the permutations sussed now!

hi I have been off the air for a while so time for an update. i have sealed and strengthend the hull by using very light glass cloth and Ezy-cote resin. this was very easy to use and i think gave very good results praticularly as i have not done glassing before. the the boat has been painted now and i am just starting to plank the deck. to plank the deck i am using the permenant marker on the edge to give the impresstion of caulking. i am verying the time the marker is in contact with the wood so the mark very's a little on thickness i think this looks more realistic than an even line, on a test piece it looked good. i will add some photo's soon, i keep forgetting to take them🤔

Yes, good to hear you are making progress.

I won't be starting building a Swordsman until getting on for winter and that depends on one of my sons moving back out to give me some room!

I've pretty much finished the plans though.

In the meantime I've bought an Infinity Hydropro 650mm yacht for some summer sailing.

Hi
The D3548/4-1100kv 910watts is outrunner brushless with rear mounting.
Depends on the prop size and number of blades you wish to use.
On the 3639-1100 the 2 blade 40mm works well, but, I tested a 3 blade 37mm and drop speed and increased amps.

thank you Canabus, i have the motor already for the life of me i can not remember what model it is! i know it is an eflight with i think 524Kv. i got it because it has a lot of torque. i also have a selection of 2 blade X and S props from 35mm to 50mm.
i will check and post the size tomorrow.

Hi, another month on and things are still progressing. I have finished planking the deck and have started on the rubbing strake.
I am using 3x5mm balsa for the strake and I will be staining it teak. I have bent the strip for the bow and stern, I soaked balsa in hot water for about half an hour. Whilst the strip was soaking i cut strips of masking tape and evanly spaced them around the bow and stern sections ready for the soggy balsa. Then working evenly side to side from the center point, I bent the strip and secured it in place using the pre-installed masking tape. Note work evenly from the center my first effort i worked from the center and concentrated on one side, when i went back to the otherside the strip snapped in the middle (the point of most stress) probably because the wood had Dryed and cooled by the time I went back to it. The strakes are currently relaxing to shape for a few days before I remove the tape.

Hi Richard

your motor has a big 8mm shaft, have you thought about how you are going to connect to your propshaft?

It might be too late now, but the early ic shafts where a steep angle, and really a bit far forward under the hull. Imagine the propeller is pushing up, rather than forward. If not too late (its actually not as daunting as you might think) you could do with altering the angle, so the propeller is close to the hull. Work on the fact that 55mm "x" prop will be the biggest, you will end up with 50mm or 52.5mm 👍
I did a lot of testing with my 4 foot 28, hulls are the same almost, we just have to now consider your battery and the resulting amp draw as your esc and motor are rated at 60a
