Bristol pilot cutter mascotte by kmbcsecretary Admiral   Posted: 1 month ago
I had to open my mouth yesterday didn't I 😭 this morning I took of the clamps to file of the excess glue and dropped the frame onto the floor knocking one of the ribs of 💩so I have had to re-glue the rib back on again so will be starting the blanking tomorrow now.i have included a couple of pics of the boat frame before I dropped it. 😱😱

Bits n pieces arrived / Aft Deck Mk 2 built ;-) by RNinMunich Fleet Admiral!   Posted: 2 months ago
6mm lime wood planks from Krick and 4mm tap from Conrad arrived on Wednesday so Full Speed Ahead. This time formers were made from the 6mm lime so no bending or slitting required, new piece of mahogany cut so that this time no inserts left an right were needed. 😊 Formers attached using Rocket cyano and a bag of clamps and left overnight. The 'Riva' tank filler caps were tapped 4mm and appropriate holes bored in the deck piece. Neodymium magnets attached to forward edge. Deck fitted and trimmed in situ for flush fit all round. Transom got scratched during this process so will need a respray🤔 Underside sealed with two coats of EzeKote and sealing / varnishing / lacquering process started on the topside. Last two pics show current status; So Far So Good.😉 Next step; fit windows made of 3mm green tinted acrylic 'glass', which also arrived Wednesday. Will now have to start thinking about what to do in the cockpit 😲 All I have so far is a 25mm ship's wheel. Furniture building is not exactly my Forte! First time for everything I suppose! Suggestions gratefully received!! Ciao for now, Doug 😎 Almost forgot! While waiting for varnish to dry I tackled an old problem with the rudder. Namely; asymmetric rudder throw caused by the rather bulky connecting rod binding on the rudder arm! Suddenly remembered I still had some E-Z Connectors from old aircraft days. Been hanging around for 35 years or so waiting for something to do! So replaced the old plastic linkage with 1mm spring steel rod and two E-Z connectors. Works a treat 😊

Graupner ranzow refitting by kmbcsecretary Admiral   Posted: 2 months ago
The deck has been fitted today after dry test fit before glueing. The timber framing and underside of the ply decking was coated in a water based varnish before applying the titebond 2 wood glue. Used a number of clamps and bungee cords to hold the deck down.

After Deck / Hatch - If at first you don't succeed ... by mturpin013 Fleet Admiral!   Posted: 2 months ago
I like the new clamps, you won't lose them in the dark. another matching gloss finish, very satisfying

To you all - thankyou. I have found all your comments very useful. You can’t have too many clamps! I also am finding my Mini Wirkstation useful plus the smaller and larger cutting green mat as a base. I’ve also learnt ‘patience’ building my Wills Everard. Thanks again.

After Deck / Hatch - If at first you don't succeed ... by RNinMunich Fleet Admiral!   Posted: 2 months ago
give up and go home! Oh! I am home 😁 Since I need access to the rudder the after deck has to be made as a removable hatch. Would you believe at the last refit (25 years ago) I actually managed to shoehorn the RX and RX NiMH battery in there as well!? Pic 1 shows what it looked like when I started this refit, after 20 odd years in the cellar 😲 Anyway, I wanted the deck to be mahogany to match the cabin roof and as a hatch it was obvious that it would need a subframe. Pic 2 to 5, had to open a new bag of chomp chomp clamps 😉 Trial fit Pic 6. SFSG! Under side was sealed with two coats of EzeKote and fixings added; neodymium magnets at the forward edge, domed captive nyloc nuts glued into the under frame at the aft edge. Pics 7 & 8. These will then accept 4mm studs screwed into Riva style fuel filler caps to hold it down and (hopefully) keep it watertight. Mahog was then finished in the same laborious and patience testing process described above (or is it below😲) for the cabin roof and decks. Pic 9 shows it screwed down with normal 4mm 'Camembert' head screws - Why? see below 😆 Finish was OK.. BUT After leaving screwed down overnight a hairline crack had developed 😡 Pic 10. Also, I didn't like the 3mm fillets between the hatch deck and the main deck, and was wondering what to do about the lip on the bulkhead at the rear of the cockpit. There was a chunk cut out in the middle. This was where in the old days we had a tiller bar to set the rudder for Free Running on a great circle (Radnor Park Lake in Folkestone - side note for Graham P74, probably before he was born😉) Sooo .... machined the lip away, removed the 3mm fillets, made a cardboard template for the new deck-piece and tomorrow is another day. Wonder what I can muck up then !!?? 😊 G'night all, ciao Doug 😎 Oh yes the Filler caps - drilled them on the lathe for 4mm thread clearance, dug out the tap set, selected 4mm 0.7mm pitch ..... Oh S..t, only a tapered tap which starts cutting at 5mm. Hole in the cap is only 5mm deep.😡 Immediately ordered 4mm parallel machine tap, should be here on Wednesday. No sweat, should have deck hatch Mk. 2 finished by then 😎

I came across those clamps by luck a few weeks ago. Had gone to Homebase (one of those large DIY/gardening/kitchens etc. superstores) with my wife for something she wanted and stumbled across them, and thinking they look useful bought a couple. When I went back again a few days ago I virtually cleared the stock! Could do with getting a few more though because as you can see and know you can soon use them all up! I'm really lucky with the IMBS as it's only about 20 minutes away! Been there two years in a row since getting interested in the hobby. Chris

Thanks Chris, entirely understand re downloading pics from camera. 😁Those blue jobs look neat, haven't seen any like that over here - yet! I have 'oodles' of the little X clamps you've also used and a few mini alu G clamps. They are virtually thrown at you at the check outs in the DIY stores here - bag of 12 for a quid or so. Wish I could get to the IMBS 🤔 Re quoting posts; "PS Is there any way of quoting posts on this site as I haven't sussed how to do it if you can?" I haven't found any more elegant way of doing than that! Copy and paste (Control+C and Control+V) and putting it in quotes in the new post. Happy clamping 😉 Looking very good so far, cheers Doug 😎

Smiffy - they're the ones. Agree about the bigger spring clamps, I struggle with some of the larger ones and I don't have arthritic hands! Some of that type can be a bit too strong for delicate joints as well, probably the smaller plastic G clamps would be better suited as light as well. I have to say we are pretty spoilt with all the types of clamps etc. that are available nowadays. Chris

You are absolutely right Doug but it was quite late with work (getting there, down to 3 days!) the next day and couldn't be ars@d to get the photo off my camera! But photos attached with other clamps pressed into action as well as only straight pieces of timber and not as much force required. I picked up those one-handed clamps from the International Model Boat Show and they are good as well but I only have two. Chris PS Is there any way of quoting posts on this site as I haven't sussed how to do it if you can?

Good point. Here is a picture of the clamps I nipped to B&Q to buy yesterday before the snow started. I really wanted more of the smallest size on the right but they only had one. The set of six larger ones were cheap enough but the springs are a little strong for my arthritic hands - in fact I have to use both hands to open the largest ones! The toolmakers clamps have gone back in the workshop (I am building Miranda in my study indoors as I don’t like sawdust getting on my machine tools - don’t tell the boss!) I do have a couple of the scissor type clamps that Chris mentioned but have found it too easy to put too much pressure on delicate joints and they are quite heavy so have to be supported so that there is no distortion as the glue dries. They are called “Quick-Grip Handi-Clamp” and are known as “curved bar clamps”. All the best Smiffy

Side skins by mturpin013 Fleet Admiral!   Posted: 3 months ago
To enable ease of application of the side skins I decided to raise the building board up to 45 degrees, this allows a better view of the proposed joints Before fitting the bottom skins the side skins have to be trimmed back to the stringers and deck line again using a red pencil to show how much material is being removed as I approach the stringers with the plane. Having done that little job it’s time to shape the skin. I followed the same procedure as I did with the side skins. Again after some time I got a fit I was happy with from the stern to the start of the bow curve. At this point I pinned the skin at the B2,3,4,5 leaving enough material to trim to the bow curve and also trim the cut-out where the skin joins with a butt joint as opposed to the overlap from bow to stern, this is all done prior to bending. Notice the steel shim protecting the chine from being cut as the bottom skin is trimmed for the overlap of the side skin. The bending was done simply by soaking in hot water for 5 - 7 mins and then forming around a suitable size paint tin and left overnight to dry. I first pinned the stern end dry and then epoxied the bow area then followed by more epoxy and progressive pinning towards the stern using brass pins into the bulkheads and smaller pins along the overlap which will be removed when the joint is dry. I made a tempory clamping arrangement at th bow by pinning some scrap ply to the top beck atea to enable clamps to be used, notice the use of a mirror to be able to make sure the joint had come together

I've got a number of spring type clamps and Bulldog clips etc. but having read that glued joints benefit from proper clamping I bought a number from Homebase which are of a scissor type which you apply pressure to to clamp and release via a lever. I've glued some timber bent to a curve, so under pressure and the joint is sound so happy with that. Will have to get some more! I'd already got some G clamps etc. of different sizes but I like these scissor type.

Hi - like Ron I am just getting started (again) having come back to model boats via model engineering. I built several as a teenager in the 1960’s including HMS Cossack, an E Boat and the tug Bustler,all from MAP plans and so where in the garage there is the unfinished hull of HMS Kent. As a break from constructing a 3 1/2” gauge steam locomotive I built the twin cylinder oscillating engine for the steam launch Miranda by Basil Harley (first published in 1983) so thought I had better build the launch as well. With regard to clamps I have been making use of toolmakers clamps from my workshop, as you can see in the photo of the keel and hull formers, but need to go and buy some sprung ones that are a bit less fiddly! Pictures attached are of the beginnings of the hull and the engine. Smiffy

Fortunately being a former architectural draughtsman I'd got all the drawing equipment that I need. You're bang on as regards clamps, I've just had to pop round to Homebase and get some more for my current build! You can never have too many! Chris
