My cabinet maker Granddad always said to stain the finish , never the wood, as stain can kill a grain. He would always use shellac/French Polish and then stain over that with a stain filled further coat of french polish. The same is done with real Rivas and no other boat can claim the finish that Riva always got with stain over Epiphanes varnish. I use cellulose sanding sealer on the wood, then a spirit based stain (NEVER acrylic water based muck) on the sanding sealer and then varnish, proper spar varnish to get that lovely glow. I have always used steamed Pear to represent mahogany in scale, but it does need a little darkening and that's how I do it. That way you control the colour, but don't "kill" the grain. Grandad also said , "always cut wood, boy, don't scratch it, make it bleed", so I became a dab hand with a cabinet scraper and use very little sandpaper. Here, as they say, is one I made earlier using exactly these methods. Martin
If you intend to stain the wood don't use sanding sealer first as the name suggests it seals so your stain won't take. as for simulated planking I suggest you sand the deck as smooth as possible (down to 1000 grit paper) and the using a scalpel type blade score the deck lines, but be careful as any slip will show on the final deck. After scoring the lines use a stain to rub over the deck and immediately remove the excess with a cloth, the stain will have more effect in the scores thus showing deck lines. When dry remove any excess with white spirit and leave to thoroughly dry, then sand again. This should leave you with a planked deck look which can now be sealed followed by coats of lacquer - Halfords do a clear lacquer. I suggest you try on a piece of scrap ply first. good luck
I have a Huntsman 31 model I am refurbishing. The paint is peeling off from age, the muppet who painted it only applied one coat (Me), the Humbrol enamel was probably too thick for the fine grain of the birch ply and spruce. I am planning to start with cellulose sanding sealer as it is nice and thin so should get a good key into the grain. So.. What paint should I use over the sealer? Some parts of the ply I want to look like teak deck planking so first I think I need a stain. Then line in the planks with fibre tip pen followed by what type of varnish? Some of the spruce needs to look like mahogany so do I stain it or use some sort of paint? Thanks Steve
I am a bit stuck as to what type of paints to use on my Thornycroft MTB. Do I use gloss or matt? What type of paint is suggested Acrylic, emulsion, etc? Who can supply - say - 250ml of any recommended paint as I will probably need to apply at least two coats. I have already applied sanding sealer and undercoat and now need finishing paints. One for under hull and t'other for topsides. Any suggestions for a supplier would be greatly appreciated.
I agree with Doug. But the ezepoxy and glass cloth s necessary for strength. I have made the top cowling of my Darby stepped hydro of balsa to save top ham,per, but despite coats of sanding sealer the knocks keep coming and spoiling the surface, so you will need the epoxy/glass combo to get a good finish. And, of course St. Canute is a steel plated ship anyway, so you need a good hard surface to get a decant paint finish that won't show every tap and knock. Martin
Hi Gardener, Don't know the Sadolin stuff, I use Billing Boats stains meself, BUT whatever you use, esp on balsa, apply a coupla coats of sealer first. Then at least one or two coats of clear satin varnish; e.g. from Lord Nelson range from Holland. THEN AND ONLY then, apply your stain til you get the depth of colour you want. After that seal with matt, satin or gloss varnish / lacquer according to taste😉 That's the way I did my Sea Scout 'Jessica' renovation, see blog on this site for results!!! Coupla sample pics attached. The whole process is described in the Blog. Otherwise the balsa will soak up all your stain and still not look right 🤔 A 'preserver' as such is not normally necessary if the wood is properly treated inside and out; sealer, stain, varnish etc! Or just EzeKote resin inside. Stain no needed inside of course. Good luck and above all have fun with your endeavours. 👍 Keep us 'up to date' ('on the running' as my German friends would say; 'auf den Laufenden'!) 😁 Cheers, Doug 😎 PS I like Danish Blue meself 😁😁 On the other hand; I wouldn't have used balsa for speedboat deck in the first place. I use a close grained marine ply 0,8 or 1.0mm. Takes the stain better and looks more realistic. Balsa is too coarse grained for stain and varnish on scale speedboats. Thick coat of paint ... OK. On the cabin roof and after deck (which I had to renew) I used 1.5mm mahogany veneer. If I had to do it again I would use a close grained 0.8mm marine ply (birch or pear) and cherry stain (also Billing) as I used on 'Jessica's deck.
The white metal fittings supplied with the kit are somewhat lacking in detail and some are overweight to say the least. I decided to produce some life rings to my specification I had tried to find suitable replacements on the web without success. So how to produce the ring part. I first tried with plywood but the finish achievable was not acceptable (can be seen in the pictures) so I then decided to use Bamboo (Ikea phone stand) for those who have followed from the start the same material as the grating on the foam tanks. First I cut some rough circles out of 10mm bamboo sheet and drilled a 10mm hole so it can be mounted on a 10mm screw mandrel. This allows the piece to machined on one side and then reversed and machined on the other side. The tool I used was ground with a 22 mm radius to produce the shape on one side of the ring and then when reversed and machined again the tool actually “parts off” the ring on the inner diameter leaving the ring free on the now remaining peg, the finish on the bamboo was good enough without any further sanding. The next step was to put a slot in the OD at 90degree intervals to hold the “rope” in position while the rope is bound in four places. The easiest way was to make a jig to hold the ring and to keep the rope in place while it’s glued into ring, it can then be removed and bound in four places each turn being super glued to keep it in place. Next job is to give a coat of sanding sealer that stiffens the rope and seals the wood. The rings are theoretically held to the cabin roof with clamp type brackets so again to ensure consistency I machined a piece with a suitable profile. I then cut radial slices to create individual brackets. The rings will actually be fastened to the cabin roof with 2 x 8BA bolts this is to enable them to be removed for painting of both the ring and the roof. At a later painting stage, I will be giving them two coats of grey primer and three coats of white, then hand painting the rope loops with red paint. The finished rings are much lighter and hopefully look more realistic.
Well it has been a while but I can now continue with the renovation. I have purchased most of the weaponry from Battlecraft and I must say that I am impressed with the quality. I will add pictures of these later in the build. I have started to prime all of the wood. Removal of the final areas of the original paint was a task but I got there in the end. I have applied sanding sealer and rubbed it down with 1000 grit wet and dry. It is starting to look and feel quite smooth. Have you built the 50cal guns yet Doug? I would like to buy some but I am concerned that they might be a little brittle for me to handle.🤔 Just a couple of questions to ask before I get on. Can I have suggestions as to who supplies good quality wooden kits to build at reasonable prices. I need to consider my next project. I want to buy a 0.8mm air brush for the larger areas as I am finding 0.5mm too small. I have my eyes on an Iwata HP-EP. This is for sale on ebay new at £122. Are there any suggestions for a better and or cheaper solution. Thanks.🤓
Evenin' Neville, I told you you'd get the hang of it pretty quick. (It was either that or you'd burn the house down😲)😁 Seriously; I'm proud of you👍 You had the guts to give it a go and you're learning fast 👍 Hat off Sir! A few observations; (Colin might also have some at this point, had a very nice chat with him on the phone this afternoon - but that's another Encyclopedia Britannica!) #1 If the paint scraps are smoking the gun is too hot or too close, or moving too slow. Wind it down to 350 and see how that goes. Back up to ~400 if seems necessary. #2 Bow cracks; I see a bodge up there where someone couldn't bend the skin properly or, benefit of the doubt (In dubio pro reo!), maybe it was collision damage. Whatever; filler in a thin crack will always vibrate out again sometime😡 Try to get at the inside and seal it with two layers of fibreglass tissue well soaked in resin, EzeKote is what I used. Wait about 10 minutes before applying second layer. Then it should bond well with the first. When that has set (ca 20 - 30 minutes) then you can apply some fine filler from the outside. When set sand smooth and seal the whole hull outside with two layers of FG tissue. Sand smooth and if any bare wood appears apply wood sealer or EzeKote thinned with 10% warm water. Don't overdo the water or it takes yonks to dry and set - Yes, it happened to me🤔 Then continue with priming / finishing as described above; or look in my Sea Scout 'Jessica' blog for the fine details. The beauty of using EzeKote for all this is that you can get a whole hull done inside and out in one day and no mixing ratios to cock up😊👍 If it's any consolation to you; when I did all this on my fish cutter and PTB loads of filler went soft and fell out as well, and the 'goo' holding the prop shafts in my PTB as well. No sweat as I wanted to realign the shafts anyway! TIP: I removed all shafts rudders and any other protrusions in the way so there were no 'twiddly' bits left to make things awkward. Leaving the odd patch of sanded paint which is still firmly fixed to the wood is OK; as long as you can't feel a 'bump' with your finger tips and you are going to seal it with resin and primer anyway. Then it can't react with the new paint. Here endeth the 3039th epistle from Admiral Doug. Will all dissenters, contradictors and other lobbyists and Trump lawyers please queue up at the Spanish Inquisition Office next door. Take a number, we'll grill you in turn 😁😁 How do you like your stake? Cheers All, Happy building and renovating, Doug 😎 Now back to me fish cutter gearbox, mechanical gubbinses are not really my strength🤔 HAMMER, have you got a minute please!? (Viewing / reading tip; click on the thread title, then you can read the the structured version in paragraphs as I wrote it 😉)
Now I am in the swing of planking I may as well do all the remaining decks that need planking. Therefore, very much the same procedure as before with a mahogany border, followed by caulking the inside edges of the mahogany border, then cutting the planks roughly to length, and then finally trimming on the disc sander for an exact fit. When all he planks have been dry fitted, they can are removed and glued with aliphatic glue. A couple of days to completely dry then it’s on with the sanding before finishing with sanding sealer I marked all the nail holes using the marking tool I made. This is all on this deck until final finishing which will be done with all the other decks.
Well if you have read the “Leaking Boat” thread you will know that my cunning plan to fix the leak failed………….. Even after drilling holes in the boat (?!?!), pouring in sealer and persuading my ‘assistant’ (I think I am married to her, but it was a long time ago now to be sure) to shake the boat as you would a cocktail shaker to distribute the fluid over the insides (not seen her move like that in thirty years)……………………..Did not do the trick. Yes I know you told me! I am now not in a place I wanted to be. No sailing for it this season, facing the prospect of a lot of dust and over-spray and trying to apply skills I do not have. I am at the edge of my” River of Styx”. The images show I have reluctantly collected together items I have for stripping paint. The large wire brush I have in my other hand! So I have had a bit of a go at the ‘red stuff’. Looks like a large area to tackle and then I went to investigate that ‘funny bit’ on the side of the bow. Well bits of filler flew off in all directions and exposed this crack which I hope you can see to the right of the metal rule. Could this be the source of the leak? Well it is two compartments away from where the water collects. On the other hand someone mentioned water passing along the ‘layers?......... Am I really going to need to strip all the paintwork down to the wood or is there something else I could look for as a clue? Most of September I will not be able to function much so I will have a good go whilst I can. It really does seem to suggest I have “bought a pup”. All the best. NPJ
NPJ, Dust isn't a problem until you come to refinishing. Do it all outside. I always spray outside and still do it up wind. Sprayed cellulose grey primer on my Crash Tender on Saturday and primer and off white enamel on my Chris Craft yesterday in a breeze, so stood upwind of it and all was well. Also rubbed down cellulose sanding sealer, dry. Dust just blew away. There's always a way round stuff. Cheers, Martin
I first cut the base material to size allowing a card thickness all round for final clearances. The lower deck has a number of features in it that need to be measured. I took dimensions from the plans and marked out the base. Again following the upper deck which has a mahogany boarder I cut and planed a further amount of 6mm x 1.5 strips of material. I started by outlining the mahogany boarders, Some years ago I made a mitring device for picture framing which has come in very handy for doing the corners. Having all the pieces cut they are then glued and temporally pinned in position until set. The next job is to prepare all the edges with black card and then measuring each plank across the width starting from the centre line. I must take into account how the planks sit against main access hatch and the battery hatch opening however, all seems to look good but until each plank is positioned and glued with its caulk divider it’s difficult to tell. When preparing each plank I first cut each piece oversize with wire cutters then using the disc sander I trim square one end, then place in position and mark for final length and finish again on the disc sander giving each plank a nice push fit Because lime planking varies in colour across a batch I numbered each plank across the deck varying the pattern of colours as I cut each to length. Next I cut a number of card pieces to length and start to glue (using Aliphatic glue), plank, followed by card filler across the half width, then repeat the other side. Finally the battery hatch and main access hatch are treated in the same manner. Next comes the finishing , I use a very fine grade on my belt sander (I attach a block on the underside of the main access deck to control the sanding process) to remove the majority of excess irregularities followed by an orbital sander for a fine finish. If there is any staining by the black card residue I simply remove it with a pencil rubber. Next I put the nail holes in again using the jig I made to ensure uniform spacing and then gave a coat of sanding sealer. Final finishing will be done as a complete assembly. Preparation of the side panels is the next process before final assembly
Hello everyone, it’s been a while since l made a post about my ongoing model St Canute, mainly due to the heatwave we’ve just been through, however l have just completed laying the decking strips, which l have to admit was going well until the last few strips to the edge, boy oh boy did l struggle. I jumped the instructions as they do say to plank the hull first. At times l just sat there looking at the decking trying to get a reasonable edge and curve. I have attached some photos which some of you professional model makers will spot the errors, but it’s the best l can do so long am pretty pleased with the outcome. I have a question, should l now apply some sanding sealer to the deck strips? l am just a bit worried not to sand the deck strips too much. Any advice would be very much appreciated. I guess now l must start with the hull planking which l am apprehensive about, but hey ho it has to been done. Thanks everyone l will keep you updated from time to time, if anyone out there is also building this Billing Boat st Canute l would love to hear from you. Cheers everyone, Richard.
