I did wonder why you would have an inspectors visit to look at the joints, then the penny dropped,

Joe.

Cheers Joe, that made me laugh out loud.

Aye, that solder and torch is a great help for the shaky hand.
Probably get a bit more done this evening

Ray.

Really nice job Ray the boats looking great

Capt Podge · « **Reply #352 on:** April 09, 2022, 04:59:07 pm »

Thanks Mark and it's turning out better than I thought it would.
The boat isn't perfect but I'm happier with it now than I have been for a long time - getting to feel that completion isn't so very far away now.

Hi Ray, I use the same torch for fine work, it's great for pinpoint heat. I've not used the paste, but looks like it's working well. Looks the boat will be ready soon..!

Best regards
David.

Capt Podge · « **Reply #354 on:** April 09, 2022, 05:35:45 pm »

Cheers David and yeah, the paste makes soldering much easier (for me anyway) - just apply the paste and heat the metal near the joint and it flows to create a fillet.
The instructions say don't allow the flame to touch the paste, otherwise it won't work.

Saved me a lot of frustration anyway

Ray.

Well, that's another "easy" task that turned into a nightmare...I was chuffed to bits when I got the first 2 uprights done. Next session the torch refused to light - "must be empty" I thought - wrong. Okay then, did a bit of reading up and it seems the cheap lighter fuel tends to block the head up with some sort of contaminant. Right-oh then, lets take the head off and give it a blow through - still no joy...
Being a bit naïve I decided to try clearing it with a pin and ended up puncturing the membrane that controls the flame output - so instead of a nice blue flame I ended up with my own personal Olympic torch!

Tried to make a new membrane with silver foil - no joy.
So, the only option left was to buy a new one.

Managed to order a Dremel kit through screwfix on Thursday and picked that up on Saturday.
(I'll post a link up later)

Anyway, got stuck in with that but for some reason the solder paint just wouldn't take and after 5 more failed attempts I reverted to using ordinary solder and flux and Bingo! it's finally done.

So then, off the Jig and onto the boat - holes drilled and pulpit rail temporarily fitted for the photos then back on the jig, ready for painting. (Phew).

That's where we're at now....here's a few photos...

I've got that joy to come, multiple times, having bought a Proxxon torch and the solder etc. sometime ago.

Chris

Capt Podge · « **Reply #357 on:** April 17, 2022, 11:36:29 pm »

Hi Chris, hope it all goes well for you - the dremel kit is quite good, used the blow torch and the solder tip so far - seems okay anyway.

Ray....

A few years ago I had 2 Durotech torches [a Blue anodised pencil] [same as your red anodised] it worked perfectly for a year then gave up the as a spluttering Ghost

so despite my expert cleaning

.....it was doomed never to accept ignition or light again

Then within a week, the larger 13 month old larger hand held Durotech unit also failed [no splutter, just dead].......both from the same Electronics Distributor who diagnosed dirty fuel, and apart from that out of warranty

So stuck between the rock & the hard place I found

1. another Durotech@ $34.00 with 12 months warranty [local purchase]
2. a Benzomatic @ $54.00 with a 3 year warranty [local purchase]
3. a Proxxon @ $84.00 with a 12 month warranty [included $18.00 postage]

So you can see here, I chose the Benzomatic which provides a reliable small flame without splutter

I also have 2 larger can mounted burners which provide an excellent source of large volume heat, with the smaller diameter of the two burner suitable for silver soldering larger items

Hiya Derek, that's quite a collection you have there and if one of them blocks up then you can still carry on with another. Not a bad idea.

I did a bit of searching on you-tube and watched a guy convert his pencil blow torch by cutting the filler end off, fitted a length of rubber tube to the body, attached the other end to a standard fitting which attaches to a camping type gas cannister and it will last for ages - no need for continuous lighting - plus he uses a vibro dish to clean the head before each soldering session.
Wish I'd seen it before I knackered mine.

Still, we live and learn.

Ray.

Hi Ray The end justifys the means and the end result looks fine to me mate, when it comes to touches ot looks like a lottery I bought one that looks like Dereks but cost me £8 on ebay that was a couple of years ago still working ok .

Cheers Joe, very much appreciated mate.

For some reason I can't get the link to work but anyway, the set I've bought from Screwfix is the Dremel Veri tip - expensive but it got me out of the frustrating situation I was in.

We're not too far away from completion now

So, here we are, 4 years, 6 months and 19 days later and...SHE's DONE!

The pulpit rail was painted with a sort of chrome although looks more silver and installed on the boat...

Capt Podge · « **Reply #363 on:** May 02, 2022, 10:32:43 pm »

...fairleads and bollards added and the pesky inspector back again (this one's for Joe)

...

Capt Podge · « **Reply #364 on:** May 02, 2022, 10:36:31 pm »

...and an attempt made to copy Joe's air-scoop design c/w Fairey logo.

Capt Podge · « **Reply #365 on:** May 02, 2022, 10:39:11 pm »

...a few more

Capt Podge · « **Reply #366 on:** May 02, 2022, 10:43:47 pm »

...hoping to get her maiden voyage sorted out tomorrow.

(didn't realise the decks were so dusty - that'll have to get sorted in the morning)

Just a couple more shots of her sitting on my upended wheelbarrow

Ray.

radiojoe · « **Reply #367 on:** May 02, 2022, 11:04:52 pm »

What can I say Ray except she's a credit to you mate, great job on the air scoops

Joe.

Capt Podge · « **Reply #368 on:** May 02, 2022, 11:13:30 pm »

Cheers Joe and very much appreciated and very many thanks for all the help you have provided - especially your encouragement

It's been a long journey but, as you know, the satisfaction in completing the project makes it all worth while.

Aye,
Ray.

DJW · « **Reply #369 on:** May 03, 2022, 09:29:30 am »

Nice result from all your hard work Ray..! And look forward to seeing the pics of her on the water.

Best regards
David.

Capt Podge · « **Reply #370 on:** May 03, 2022, 01:40:54 pm »

Cheers David and actually had her on the lake this morning and found her to be nose heavy and digging the bows in when I opened the throttle.
Adjusted the ballast which brought her almost level and steerable but not able to get up on the plane.
Think I may have to go for li-po battery for the extra power?

When I get it sorted I'll update on here along with photos, maybe even a video if one of the lads are available

Ray.

DJW · « **Reply #371 on:** May 03, 2022, 02:52:09 pm »

Hi Ray

Looking back in the thread it looks like you have a lead acid battery forward of the motors, I'd have thought moving away from lead acid would lighten the boat overall, lighten the bow in particular and allow the bow to lift a bit easier. I think I saw an Mtronics ESC, I'm not sure all of these support LiPo batteries, depends which you have. If it doesn't maybe a Nickel Metal Hydride 7.2V would give a few extra revs if your lead acid is 6v and be a lot lighter I'd have thought. What spec is the lead acid..?

Best regards
David.

Capt Podge · « **Reply #372 on:** May 03, 2022, 04:04:22 pm »

Thank you for your reply David.

The battery is 12v 3.3Ah/20hr sla
I changed that one for another sla 12v 1.2Ah, that's the only other one I had with me.

The esc is Mtronics 15amp.

I've got 7.2 nmh 3300 in the wksp - I'll give that a go next time.

Regards,
Ray.

Hi Ray It took me several attempts to get the performance right on my Huntsman, my first set up was 7.4 volt Nimh battery, an Mtronics 30 marine tio, and 35mm three blade props she ran more like a fast tug, I then change the battery to a 2s lipo although a similar voltage there was a marked improvement but still not on the plane, I then changed the props to 30mm three blade and oddly enough she was faster but still not quite right, I then changed to a 3s lipo and that did the trick well up on the plane and a lovely bank on the turns, You should be fine with a lipo battery all the Mtronics marine ESCs take any battery from 6 to 12 volts, I did fit a fan from an old PC over the ESC that cuts in with the throttle, if all this is any help. the 3s lipo is a 5000mah and I give up before the battery dose,

Joe.

Capt Podge · « **Reply #374 on:** May 03, 2022, 06:06:35 pm »

Great info there Joe and will help me to 'get it right'.

If I was to go down the lipo route I would also need to buy a lipo charger etc.
I'll give Component shop a call... I'm not too concerned about the extra cost for equipment and I know I'll be building other boats that will use the lipo stuff - but that's for future anyway.

Cheers mate,

Ray.
