    Tug Lady Laura
    I have just bought the David Metcalf kit of the tug Lady Laura from the new owners/distributors Tony Green Steam Models. Checking through the kit I have already found a few problems - the vac-moulding for the 2 halves of the funnel appear to be quite badly distorted and, even when I get round to cutting them out, I feel that they will be almost impossible to join together (the plastic is quite thick): mention is made to refer to construction diagrams but, among all the paperwork and drawings, I can't find any diagrams apart from ones for the rope capstan, the anchor winch and the tow hook (and these are not numbered). I have emailed TGSM with the queries but I was wondering if any members have built or own this model and can help or comment please? Derek.

I will be making many parts from Basswood and balsa. Thanks to a couple of generous friends I have the plans and templates. The built model is a stolen picture from Tim's beautiful build of the same model in 2013. Hope you don't mind Tim. You have set the bar high. I can only hope to do as well. This one will take time.

    SURFACE DRIVE EXPERIMENT
    Thought I'd have a go at a slightly different type of drive for the future Stiletto project, and try and make a stinger drive into a surface drive, to have drive and steering all in one. I bought a stinger drive for a 5mm shaft and a couple of car CV type driveshafts to steal bits off. Made up a rough dummy transom to test it out. Milled a bit more clearance in the back of the stinger bracket for the CV, made a couple of transom-drive brackets, (modified from hardware corner brackets,) made an Acetal bush to replace the usual cable drive in the back of the stinger, (to support the shaft rear), and a small 4mm-5mm adaptor shaft to go between the brass motor connector and the inner CV for the test. There is a huge amount of slop in the Chinese connectors and the red d/shaft has a loose sliding hex inside, so not the smoothest running. Also no bearing in the transom to support the future one piece motor to CV shaft. The final shaft (test dummy) also is free to move in and out, but will be properly positioned once the stinger shaft is made, which should smooth things out. A steering arm to make as well if I can get it working properly. Probably take a while to get it working smoothly and it may not even be suitable, but fun to try anyhow. Have built a shaft slot in the keel just in case ๐Ÿ˜. Motor for the test was the slowest I had, and run slowly to avoid possible flying bits. The final motor will hopefully be the 540 S V-spec fan cooled 36/52 1100kv in-runner which I'll be water cooling. Had it for about 10 yrs, so decided it needed a home, (another experiment). 1 vid shows the amount of slop in the connector, which should be 0 if made correctly. This is why people have so much trouble with vibrations in boats. The only real way to fix it is to make your own and ream the shaft holes to size,-not drill them like the Chinese seem to do. JB

    Hi CJ, " I might try to add a little weight to drop the stern down further. " That may help a little perhaps to get at least the forefoot out of the water. But I still don't think that that 15mm prop can generate enough thrust. Would be happy for you if your next video report proves me wrong. Cheers, Doug ๐Ÿ˜Ž

    Re: Lorelei.... 1st pond trial
    Thanks for the comments and suggestions. You are probably correct that the higher revs will not do anything, but at $16.00 U.S. gotta try it. The larger jet was about twice the size, and yes possibly could be shoehorned into the hull, but that may be a later build. I just wanted to see if I could pull it off with the limited knowledge I have. One other thought I had was to extend the outlet of the jet further. Currently it sits just below the water surface. I might try to add a little weight to drop the stern down further.

    Re: Lattice masts
    Hi Norm, I would guess angle steel, to minimise top weight and maximise inherent strength. Been on the odd ship / FAC with such a mast and they were built using angle profile. In a model probably best constructed from styrene profile, conclusion I came to when making the depth charge rails and bridge wing supports for my H class destroyer. Soldering brass profile for such a mast could become a 'job for life'๐Ÿค” Happy gluing, don't get too 'stuck in' ๐Ÿ˜ Cheers, Doug ๐Ÿ˜Ž BTW: ref deck colours, see Norman Ough's comments here, click on the 4th pic- https://www.vintagemodelplans.com/products/digital-full-size-plans-h-m-s-amethyst-scale-1-96-suitable-for-radio-control https://www.maritimequest.com/warship_directory/great_britain/pages/sloops/hms_amethyst_u16_page_4.htm

    Re: Lorelei.... 1st pond trial
    Hmmm! Good luck with the 2200kV CJ๐Ÿคž You may well get fireworks, but maybe not those that you are hoping for. But frankly I don't think that kV rating of the motor is your real problem here. OK you will get roughly 2.2 times the rpm using the same battery but I'm not sure that will help much. (BTW: You could also achieve almost the same effect by doubling the battery voltage on the 1000kV motor. You did not mention what voltage LiPo you are using!?) No! I believe that you have two basic design problems here. 1. You have applied a great jazzy offshore power boat type colour scheme๐Ÿ‘ but you actually have a relatively beamy hull more suited to a cruising type boat, with a roughly 3.5:1 length to beam ratio. Fast power boats and naval ships, e.g. destroyers, typically have l/b ratios of around 8 to 10. Reason: for the same power unit the higher the l/b ratio of the hull the faster the vessel can go. 2. The water jet! Here I admit I have no experience of water jets and do not know how their efficiency compares with a conventional prop. BUT! I think that your WJ is basically too small (15mm prop๐Ÿค”) and more revs may not produce more thrust and speed, but possibly just more cavitation and disturbance of the jet flow. Your boat is 23" you say. A few years ago I restored an Aerokits Sea Scout, built by my Dad in the early sixties. She is 24" LOA and 8.25" beam. I.e. l/b ratio 2.9. She has virtually the same hull form as your boat and is fitted with a Propdrive 2830 1000kV brushless running off a 3S LiPo driving a 30mm 3 blade conventional prop. And frankly I reckon she would run rings round your Lorelei in her present state. See attached video (U-toob link) of her sea trials or my Gallery post here- https://model-boats.com/gallery?q=Jessica I reckon your basic problem is that the water jet is simply too small, not 'jet' enough for the job.๐Ÿค” You would be much better off with the 26mm jet that you mentioned in your blog. Must be enough room for it in that hull. May just need some re-thinking and re-planning / rebuilding at the stern which may need a 'power bulge if the 26mm W/J is taller than the 16mm job๐Ÿ˜‰ Try the 2200kV by all means, look forward to seeing the results report, but I'm sure that the bigger W/J or a conventional prop ca 30-35mm is the real solution. Use the 2200kV on a later (larger?) model and the 16mm W/J on a smaller/narrower model. Whatever, happy experimenting and sailing๐Ÿ‘ Not trying to dampen your enthusiasm but hopefully to get you back on the road to success and fun๐Ÿคž Cheers, Doug ๐Ÿ˜Ž https://www.youtube.com/watch?v=zPgYicA0yGw&t=106s https://www.youtube.com/watch?v=b0BWJ3duzDw&t=15s

    Re: Setting up the Winches
    This system's pretty common I think. I know it's a similar set-up to what "SailTails" on YouTube uses in his "Bearospace" models, but I've seen it in various forms for a decade or three. I think when winch servos became available, it superseded a system that used a shuttle on a threaded rod. This was an erector-set gizmo with rods, and a motor, or two, micro-switches, etc. It would be hard to fit in a model of less than a meter. Now, I've seen micro-servos converted to winches running loops in Footies. I went three rounds with this idea in this model years ago as my original plan see: http://todd.mainecav.org/model/pride/model09.html In my case, getting rid of the motor made implementing it possible. Now, hopefully, it works. ๐Ÿ˜‰

    Re: Static outboard cruiser converted to R/C
    Into the test tank to see if it goes forward & in reverse. It did! I had earlier powered the motors on the bench to see if it would turn over.Several folks on this side, in RC Groups, helped me determine the appropriate voltage based on their experience with similar outboards. Turns out 4.5v makes it happy. Again, many suggestions how to send 4.5v to the motor from a 7.2v battery system.Finally decided that adjusting the throttle end point on the tx was the best alternative. So, pulled out the trusty, & somewhat rusty, multimeter to set the end points to 4.5v at the motor leads from the esc.๐Ÿ‘

    Lorelei
    Started a new scratch build after getting interested in waterjet propulsion from articles by JBKiwi and Rowen. Didn't initially have a specific boat in mind at the start, just wanted to see if I can make the thing work. After looking at different hull designs, I elected to go with the Cresta which is on the KKEezebilt boat web site. I know, I know, egg crate construction! not exactly the best, however, after getting into it, this has created quite a bit of room inside for the water thruster, and it also has a very flat "V" shape to center mount it . It also turned into a very easy build up to this point. The boat frame is made of 3/32" basswood, with 1/32" sides and bottom. There is also 1/32" ply for the thruster intake, and the exhaust nozzle in the transom. The chine is reinforced with basswood strips. After downloading the Cresta Plans, I scaled up the prints to the length of 23", this seemed to be the best fit for the 16mm thruster purchased from Amazon. I initially purchased a 26mm unit complete with reversing bucket, however this one was way to big. Unfortunately, the 16mm unit does not have a reversing bucket, so it is forward only. (My ESC is a bidirectional unit which will reverse the brushless motor, so maybe it will have some sort of reverse๐Ÿคž!) Modifications to the Cresta plans include adding extra angle bracing between the floor and the bottom, modifying the transom, and cutting down the beam for the thruster unit. I also made the top removable to access the internals. The cabin area cutout will have a fake bottom to allow for wiring and connections on the subfloor. Once I get the whole boat covered in fiberglass, a float test will determine the placement of the batteries and electronics, as well as look for leaks๐Ÿ˜.
