Doug,
That has now got me thinking now. Depending on how big the scale is i am sure i will be able to find something. My next move will be to keep a close eye on Grahams build log for more information on scale and control. Martin555. ▲

Hi Graham,
"Can I simply scale the plan down to 1/6 by reducing all the dimensions pro-rata, ..." Yes you can! (As the proverbial actress said to the bishop!๐ฎ) Oops! Another slapped wrist๐ AS LONG as you make sure that what you are measuring is the true 'plan' view dimension, and not something sloping away from the viewpoint, which would thus be foreshortened. Cheers, Doug ๐ ▲

Hi Jacko,
Thatโs an alternative approach using a mechanical solution to producing the rowing motion. Iโm better at electronics than I am at making cams,so Iโm going to attempt an electronic version. Iโve written some of the code for the microchip already so the next task is to rig up a test bed with the servos so I can see if the movement is anything close to realistic. Graham93 ▲

Doug,
โFor speed control I figured that instead of servos two miniature reversible motors with ESCs might do the trick.โ The problem with using two independent motors is that you need to synchronise the speed and the phase between the motors to keep the oars working together when trying to go in a straight line. Really difficult to achieve and maintain that synchronisation unless you have some form of feedback (optical encoders?) I think on balance, using servos is probably going to be easier. Graham93 ▲

Jonathan,
Thanks for the Pololu link. I hadnโt come across those before. They look really interesting and flexible. If my current controller plans donโt work out, they look like a good alternative. Iโm planning on using a PIC 16f microchip programmed in Assembler code. When I started work in the early 70s my first job was programming a PDP11 in assembler as a CNC system for a lathe. After that I moved on to program a whole range of different processors for different applications, but always in assembler. I never really graduated to any higher level languages. The programming is coming along well, I might have something that I can connect to the test rig later this week. Graham93 ▲

Mornin' Cap'n,
Now that's a neat idea Nerys! Problem with paddling as such would be shifting the paddle from one side to the other๐ค Otherwise, especially considering the form of a coracle, he would just spin on the spot. Until he gets dizzy and falls overboard๐ฎ BUT, now you've triggered my hyperactive imagination! I could envisage a larger 'two man' coracle - with you and Alice paddling it ๐ As far as possible in these topsy turvy times, HAVE A GOOD DAY U2๐ Cheers, Doug ๐ ▲

You are right Doug, nothing I haven't seen before. I remember my son having a half clothed Action Man.
I'm following this with interest , I haven't seen many model rowing boats, but always think how clever their builders must be. On that theme, What I would like to build would be a man paddling a coracle, but I'm afraid the mechanics would be way beyond me. Cheers, Nerys ▲

"At least he kept his pants on ๐"
Even if he hadn't Graham, I don't suppose he'd be showing anything that our esteemed Captain hadn't seen before ๐ฎ๐๐ I'll be intrigued to see which way you finally go with your rowing machine. However good the electronics are you can't avoid some good mechanics for it to actuate! That's the tricky part๐ค For steering I've been considering two micro switches on a micro servo to simply disconnect power to one side or the other as required, the opposite side to the direction you want to turn. For speed control I figured that instead of servos two miniature reversible motors with ESCs might do the trick. Thinking further; using 'tank control' one could steer by decelerating one side!? To spin on the spot reverse one side!? That'd tax the coordination of any rower!!๐ค Been trying to visualise the movement required:- Lift - Back - Dip - Stroke; Lift - Back ... etc etc. Good luck๐ค Cheers, Doug ๐ ▲

Hi Graham,
Great project.... I scratched the surface of this 3 years ago - but did not progress it very far. I was going to "reverse engineer" things a little. I intended to move the oars manually to get the shape of the movement whilst connected to the servo's and read/capture the servo position/time electronically which could then in theory be reproduced. What controller are you using? Are you familiar with the Pololu Maestro Servo Controller range? - would be a doddle using scripts. The Maestro can then be controlled via a serial link from your microcontroller ▲

Hi Red,
"don't understand how this works nor even know what an Arduino is" I'll try to explain the basics of this controller as others here may also be interested. First of all, Arduino is a small module (there are several versions) which can be programmed to carry out all sorts of tasks, not just model related. Several members here use them for lighting controls etc. I have no experience with using Arduino but what I use (PIC) is capable of being programmed to carry out similar tasks. In terms of the rowing controller, just consider a single oar to start with. It has two servos to control its movement, one to dip the oar into the water, and one for the stroke, to pull and push it. If those two servos were connected directly to a receiver on channels corresponding to a two axis joystick, then it would be possible to create the rowing movement by moving the joystick round in a square, from bottom left to bottom right then top right to top left and back to the start. If the two servos for the other oar were connected to the second joystick on the transmitter, then in theory it would be possible to control the rowing of both oars to go forwards, backwards and turn by moving both joysticks simultaneously. However the coordination needed to do this would be difficult. That is where the rowing controller comes into its own. The rowing controller simulates the movement of each joystick by generating signals for the servos similar to those that would be produced by moving a joystick round in a square movement. The advantage of the controller is it can simulate the movements of two joysticks better than I can manually, and it can also adjust one 'joystick' relative to the other to control the direction of rowing. At least it will once I have that part of the program running - it is nearly there. Sorry if any of the above is teaching anyone to 'suck eggs' Graham93 ▲

Mornin' Red,
"Cant even remember Ohms law and how to apply it!" Herr Ohm he say- Current (I A) flowing in a resistive load (R Ohms) is proportional to the voltage (V) applied across it. I=V/R. Conversely V=IR or R=V/I. The latter being very useful for calculating dropping resistors for LEDs of various max current ratings and supply voltages๐ DC Power (P Watts) dissipated in the load equals volts applied x current drawn. P=IV. Thus P=(V/R)V =Vยฒ/R or IยฒR. Helps to define the resistor size (power rating) you need; e.g. 1/8, 1/4 Watt etc. Alles klar Herr Kommissar? ๐ Now where did I put my pink gin? ... "JEEVES!" ๐ ▲

As a fellow Doctor i would like to say that is some major surgery you performed there. A very tricky operation indeed. And i am glad to see that your patient has made a full recovery. It is good to see he is using the special equipment provided to build up his stamina and muscle strength and soon he will be able to take on his task to row across the local pond. I am also looking forward to seeing him and his boat in action. I must congratulate your wife on knitting his jumper. You both have done an excellent. Well done. Martin555. ▲

I considered using threaded rod, but it is quite expensive in small sizes. The M3 screws I found are OK, just have to be really careful drilling through the thin sections.

Graham sorry to be late with this suggestion but I would have used BA nuts and bolts there are loads of suppliers for the model steam enthusiasts with some really long examples, I've use them on the crash tender where required, however your making a great job of it keep it up

Looking good Graham, this is making me want to build another full sized fast delta like the 15ft one I built in 72, powered by a 75hp outboard. Built it a similar way on a jig, and screwed the bulkheads/frames to the jig with right angle brackets, so when I flipped the hull over I could unscrew the hull from the jig and lift the jig out.

Hi,
Thanks. Yes used tea and coffey before. The reason I use acrylics sometimes is that I need an exact match to other rigging nd I have sort of got into the habit. On a few of occasions over the years I have been asked to renovate very old statics for museums for display. You cannot and indeed shouldnโt replace any more than you actually have to on things like that, you need to conserve as much of the original as possible. With acrylics I can play about with things until I get it exactly right. I also then have a small bottle of an exact colour match in store for if I need to do more work on the boat at another time. This I usually give to the museum with notes on things so that if anybody else does it they know where I was coming from. I do the same with wood stains. I have a stock of different wood water stains that I mix up to get exactly what I want. Again this is a trick I got from an Anteques restorer years ago. You use such small amounts usually that the โsampleโ selection that I got from White friers in little bottles years ago is still in use. When I have needed more of any colour I get it by the big bottle and decant it as necessary. ▲

you could always cover the frames with a paper skin temporally so that it looks like the completed boat to see if you can get at all of the screws to release the hull. Martin555. ▲

Iโm enjoying the build, and find myself wondering what it would be like to build a full size dinghy. It would certainly be easier to get tools into the right places. But I donโt have the space, or the need for a full sized boat.. it would just be fun building it though.... ▲

Thanks Marky, Mike,
The electronics for this has proved to be a challenge, or rather the software that is embedded in the electronics. While Iโve got it working in the test rig, itโs going to need lots of tuning once installed in the dinghy if it is to actually row as it should. I think Iโm going to have to sort out a test tank big enough so I can test it at home before going to the lake with it. ▲

Hi Red,
โBe a shame to paint the mahogany - would look nice above the waterline โ Iโve focussed on trying to get the inside of the dinghy as clean and tidy as I can so I can varnish it. The outside has a few issues, especially with the nails. I would have to have taken much more care with the positioning of each nail if they were to be visible when itโs finished. A few didnโt drive in square either, which wonโt matter when itโs painted. I plan to paint it white, with mahogany trim which I think will look OK. Maybe next time, when Iโve finished this one as a practice piece ๐ ▲

Be a shame to paint the mahogany - would look nice above the waterline Graham - you are making a very good job of the Dinghy - Dumas advice on planking coloration was to use mahogany stain on the mahogany to deepen the colour . Perhaps you could test a small piece first . Also be nice painted on the inside - you can hide things better that way too !

Hi Martin,
The plan is to glasscloth and paint the outside, for strength and waterproofing. The inside will be clear epoxy 'varnished' - that's assuming it looks OK when I take it off the jig. If it looks a mess, I might have to paint it inside ๐, but I really don't want to. Graham93 ▲

Glad you like him. I was hoping someone would ask how he aged so quickly ๐ I have to admit, I had some help. When I was searching the web for the Action man to be the basis of Bionic Bill I came across a 'head reflocking' service. A sort of reverse barber๐. So once the project was underway, and looking promising, I decided to invest and I sent his head off, with some photos of the sort of effect I was hoping to achieve. What came back was a cleaned up head complete with hair and beard, but not quite the look I was aiming for. I spent a few days looking at on-line turorials on model head painting and then got the acrylic paints out. I'm generally happy with the end result. Certainly an improvement on the original .

Because it gives instruction on how to scribe the water line then we can assume it has one , I would think its just by different colours above and below , I can't ever remember seeing a rowing boat with a white line. I really wouldn't bother with one, as you say there's not much you can do about it but I'm sure it will be fine.

Mike,
Yes the plan has clear instructions on how to scribe the waterline. However, that does raise a question in my mind which I hope those with more experience than I on this site can help with. How is the waterline normally indicated on a dinghy? I don't think it is normal to use different colour anti-fouling paint below the waterline on a dinghy, or is it? Is the waterline marked in some other way? A second, and more difficult question, what target weight should I be aiming for? Martin's comments on the build looking heavy has got me a little concerned - not that there is much I can do about it! Thanks for the offer on the veneer, I'll keep it in mind. Graham93 ▲

Does it have a water line defined in the plan ? Whatever it turns out to be I'm sure it will sit well in the water, as I said before Its making me jealous and feeling I need to be doing something similar.
