RE: 85 ft Harbor Tug/Angels Gate
Dallas, I like the idea of not putting anything on the inside planking as it does look better clean, however, when I tried it on my tug, inevitably the inside wood got wet...don't ask how..[:@] and found that the moisture will creep through to the outside and will not only release the CA, it will separate the glass layer from the wet wood. The result was to strip the loose glass and redo the hull.....and I gave in to completely sealing the inside planking.

RE: 85 ft Harbor Tug/Angels Gate
Dallas - Comparing the physical size of the motor to the Electronize 30 controller, I would think that you might do well with a Pittman 3700 using the same gear ratio. Shaft speed is 3700 and your ratio looks to be 2/1 so 1800 is about right. The Pittman is about the size of a small beer can and is a robust motor. PM me and I'll tell where to get one....

RE: 85 ft Harbor Tug/Angels Gate
Working with this scale offers some serious opportunity for finishing detail. The larger problem is to decide when enough is enough. [:D] You are doing a great job and this thread provides a lot of encouragement to anyone thinking of building a real working model. I also found using a laser level to establish both the water line and aligning the driveline to be a real timesaver. I visited the Maritime museum in Los Angeles last fall and was able to get up close with the original Angel's Gate while she was returning from a short stint in drydock. Unfortunately, I was about two days late to actually see her on the blocks but a good friend who is a member of the crew gave me some pictures of the naked bottom.....they offer some views not normally seen and I post them here for your enjoyment. Maybe they will help when you finish the rudder set up. You can see the sacrificial zinc anodes which I don't recall seeing on any model so far, maybe you will be the first. Keep up the flow of pictures and information, it is much appreciated.

RE: 85 ft Harbor Tug/Angels Gate
Pete, I bought the stuffing tubes and shafts fron Harbor Models but I don't see the exact part number on their website. They likely still have them though. They were Robbe 1443, Stern Tube 195, D4 x 260 - attached to props that were for a 4mm shaft. I cut the shaft to 7", coupling to Kort with the coupling attached directly to the Pittman. Hope this answers your question. Keith.

RE: 85 ft Harbor Tug/Angels Gate
PeeJay - I am running two 60mm Korts on nmy original Francis Smith plan and agree that this is probably the largest that will fit even as a single. Having said that, I often use only one if I am just cruising as the idea of two is definitely overkill unless you intend to do some serious pulling. I set my speed controllers to half power to prevent overspeeding the boat as it will start to nose down if it is run at 3/4 of full throttle. A prop speed of 1800 -2000 rpm presents what appears to be an appropriate scale speed. Keith www.kaymac.ca

RE: 85 ft Harbor Tug/Angels Gate
This is going to get really interesting when you connect two of those beasts into that underdrive box and then into a five inch pitch prop. We should start a forum pool estimating the amount of bollard pull it will have! I'm thinking 30 lbs isn't unrealistic. Keith.

RE: 85 ft Harbor Tug/Angels Gate
While on the subject of Pittman 3700's, I run mine through a pair of FR30HX Microprocessor Speed Controllers and run them about half speed. This allows me to use a pair of 12 Volt - 7 amp alarm system batteries and have no trouble running for a couple of hours or more. These are cheap and make good ballast. I buy them for about $12 each. I also made a charger out of an old home alarm panel that I picked up for nothing. Just some thoughts for you. Given the size of you boat. you could use four or five of these batteries with good results. Keith. www.kaymac.ca

RE: 85 ft Harbor Tug/Angels Gate
"The engine drive goes onto the single input shaft and turns two output shafts at 33% less rpm" Grinder, Your thinking seems to be right on here but the above statment makes it confusing. I think you meant 33% more RPM as is stated on the website. The unit is an overdrive system when the input is on the single shaft so it will slow down when reversed by using the single shaft as an output. This will be a nice setup when you done. Expensive but very strong. The Pittmans are rated at 3700 RPM @12VDC (I think). I use them with direct drive on my tug and they perform well but am only turning 60 mm props. Keith. www.kaymac.ca

RE: Jolly Jay fishing boat
Your idea of using 2 lb. test line is probably wise but trying to predict how a fish will make the first move is difficult. I suggest you test your idea by connecting the two pound line to the boat and attach a three pound rock about 4 ' downline and drop the rock while the boat is sitting in the water. If the line breaks before the boat, you win. Regardless. it sounds like fun! Keith www.kaymac.ca

RE: 85 ft Harbor Tug/Angels Gate
Your choice of scale offers a serious opportunity to detail the build and has me thinking this might be my next project. I’m not thinking quite as big as yours but possibly something around 60�. I’m impressed with the accuracy of the laser cut and will go that way next time as well. Did you mention that the company will cut to custom scale? I notice your choice of power supply and bow thrusters are the same as I used and I can say they work extremely well. I also use the MCD Switch 8 added to my transmitter and found it to work flawlessly. I use small 12V relays on it to power anything that requires larger amperage. My only regret is that I didn’t use the 16 channel model instead of 8. All channels are used and there are still some ideas that I have and will need to upgrade to do it. One of the options I’m considering is adding a video screen radar in the wheelhouse. I picked up an MP3 player on Ebay for $15 with the intent of recording an actual video of a working radar and loading it on this unit. Unfortunately, it is slightly larger in scale so I’ll need to mask the screen behind the dashboard to get the size right. Since it also has sound ( and an FM radio), I think I‘ll add some recorded harbour chatter and have it play in the background. The big problem is how to turn it off or on remotely…haven’t figured that out yet. Keep the pictures coming, I know everyone is enjoying this build. Good stuff!! Keith.

RE: 85 ft Harbor Tug/Angels Gate
I used a product call 3M Scotch restickable glue stick available at Staples or any office supply. It works well in that it stays on when running the wood through a saw but comes off easily when you want to strip it. I usually make a second set of sacrificial drawings for this purpose. Kinko's make blueprint size copies resonably cheap. One error I made that I won't repeat is trying to buy thin plywood at a bargain price at Home Depot. It looks good but certainly isn't up to the quality offered at most good hobby stores and I am now replacing most of it on the wheelhouse and upper decks. Cheers, Keith. www.kaymac.ca

RE: 85 ft Harbor Tug/Angels Gate
You will enjoy the build as the Francis Smith plans are very well done. I am in the process of rebuiding my hull after having the misfortune of blistering between the wood and fibreglass due to incomplete inner sealing. This seems to be a common problem on a first build...[:@] You can see my original build here: www.kaymac.ca cheers and keep us posted. Keith.

RE: Bow thruster
You can get it here: http://www.harbormodels.com/site08/main_pages/propulsion.htm Look down the page and you will find it. I used a small ESC and it really throws the bow sideways under full throttle. If you watch the video on my website, you can see it swing when the tug makes a u-turn in it's own length at half speed.

RE: 85 ft Harbor Tug/Angels Gate
2003merc.. I can email you a tracing of the visor from the plan I have and you can scale it on a photocopier to fit. The trick is to get the compund curve right and then using 1/16" plywood, wet the visor and bend it. Tack it in place with CA before it dries. Tug's advice on sanding the angle is essential for a tight fit. Cheers, Keith

RE: 85 ft Harbor Tug/Angels Gate
Hi Steve, My tug was built from Francis Smith plans and there are a few pictures of the drive system posted earlier in this thread ( #22.27,34) and I have many more that I can send you of the actual hull construction. As Tug said, it really isn't a difficult build but it does take some time to lay up the hull. The best advice Francis offers is to make sure you start with a solid jig and lay the hull equally on opposing sides to avoid warping...I didn't follow this advice as close as I should have and suffered a small warp but nothing that is noticable or hurting performance. It's a great project though, good luck with it. Keith.

RE: Teak Cruiser - has a problem
Here's a little tip for those of you using 12 volt Gel batteries. Go see one of your local Alarm companies and ask them for a PC board from a "locked out" alarm panel. These are replaced boards that were code locked by another company and without the code, the alarm function isn't accessable. They have lots of them and when they are "locked" they are vitually useless as the cannot be reactivated for alarm purposes and will likely give them to you for free. However, they have a perfectly good, regulated 12 volt power supply/charger that will charge a 7 amp battery in about 14 hours or less. I use these all the time and have a few laying around. Cheap and effective. Regards, Keith

RE: 85 ft Harbor Tug/Angels Gate
Hi Tug, As I mentioned, I am interested in your offer of a good copy of the magazine article. If you or anyone else know of a source that might have an original magazine, that would become part of the tug display and would finish the project....or on second thought, does a project ever really end? On that subject, I finished my tug in August, sailed her a number of times with great results except when I found out that CA glue isn't waterproof....my bow thruster sprung a leak and severely tested my bilge pump! I couldn't figure why she began riding low in the water until I saw two separate streams of water coming out the side. I should only have the engine cooling stream but there was this mysterious second stream towards the front. Then I realized that was the bilge working. So, back to the bench for some epoxy repairs. Once I opened her up and removed most of the guts, I decided to re-plumb all the plastic tubing and properly bend, solder and install brass plumbing. I also decided to connect my deck lights to the smoke generator to let me know it is on. Now this may sound a little strange as one would think that it should be fairly evident that a smoke unit is on...but, ..when the unit runs out of smoke fluid, and you don't notice it is still on, it can quickly burn the element out. So, now. if the lights are on and the smoke isn't showing...well, you get the picture. The next task will be to figure how to run a pipe to a fire monitor that allows me to remove the cabin without having to dismantle the piping. As I said, is it ever done? Cheers Keith
