Motors by Ianh Sub-Lieutenant Posted: 2 months ago
Don't know what happened MOTOR COMPARISON Model Number Caldercraft CEM 900T MFA Torpedo 850 Nominal Voltage 12v 12v Operating Range 6-24v 12v Type Brushed Brushed Current Cons No Load 0.4A 1.9A Current Consumption Max Eff 5A 10,8A Stall Current 20.3A 40A RPM at Nominal Voltage 3000r/min 9778r/min Prop Caldercraft 75mm The Motor I am putting in this Sea Queen is a Torpedo 850. This is due to the Caldercraft motor only manages just above walking pace.
Hi This is being built from the Jotika Sea Queen Kit. The kit is quite comprehensive but I need to check the fittings supplied as some of the look a bit small for a 1:12 Boat. Also decided to change the Motor from the existing Caldercraft to an MFA Torpedo 850 as I believe the Caldercraft Motor only manages walking pace. First thing was to built a building board. I need this to also cope with a VMW 46" RAF Crash Tender.
[Score: 10/10] 46"/8800g Colleen Anne Single Propellor (3 Blade 45mm) Direct Drive to a MFA 850 (3 Blade) Powered by Lead Acid (12v) 6Amp/h Batteries Controlled Through Perkins (15Amps) ESC - Comments: Comes in Kit form ex Jotika. Suggest changing the motor to the motor supplied which is a Caldercraft.
My wee red boat after a rub down and a file/sand on the steel keel. This morning I painted the red with HMG enamel and got the green mixed in the same make enamel by my wonderful chap at Kett's Auto Paints. The mast came in two parts, so I did a slight scarf and glued it. When the joint is well set, I'll make a splint and set it in prior to a rub down and a good waxing. The steel (tinplate) parts came with the predictable rust, but with my selection of scrapers and chisels made of broken and worn Swiss files I was able to scrape most of it off back to reasonable shiny steel. The out of shapeness needed only a clout with a cold chisel type of bodywork tool in the right places to restore it to original shape. Loops were filed to lose most of their rust, but not replaced. They'll be Vaselined as a form of anti rust, waterproofing. I have some new 1.3mm cord coming from Caldercraft. I just hope I can remember how it was rigged. I ain't great with knots. The sails were absolutely filthy with some sort of oil based grime, but my dear bride sorted them out with Vanish and a good hand wash. Pics of those tomorrow. I love this stuff.! Martin
I just got a lovely old Star SY 3 yacht and needed to clean some filthy sails. My wife suggested Vanish and blow me down with a genoa, it's working. A generally mid to dark grey (I believe oil based) grubbiness has all but disappeared and I should be able to re-rig them with some new off white 1.3mm string from Caldercraft fittings at Cornwall Model Boats. I can make new styrene bowsies and any metal hooks and loops. I've scraped the mast and bowsprit fittings of rust until they look shiny again, repaired a broken mast and repainted the green edging which had been a bit knocked about. I love doing these restorations more than making new stuff! Martin
[Score: 9/10] 39"/3400g Sir Kay (T241) Capable of 3mph and a runtime of 30mins Single Propellor (3 Blade 50mm) Geared to a MFA Geared 2.5:1 (3 Blade) Powered by NiMH (7.2v) 3Amp/h Batteries Controlled Through Mtroniks (5Amps) ESC - Comments: This is my Sir Kay (T241) - Round Table Class Minesweeper. It is from the Caldercraft range and I was fortunate to recently acquire it - I would have much preferred to have built it but couldn't miss the opportunity of it being given to me by an old retiring modeller. It just needed new RC throughout, a good clean, a tidy up and some fresh paint here and there plus a bit of rigging renewal. Not tried it in the water yet but will do tomorrow at our Club meet. Tried it today and it sailed really well, stable and sits perfectly on the water and one 3000mA 7.2 NiMH battery lasted all afternoon - so pleased with it. Have now completed the rat lines on the rigging so looking a bit better.
Hi Dick, I have a few tugs and the largest at 49" uses a geared 540 running from a 12v 7ah sla battery giving a good 90mins running time. This model weighs in at 15 kilos ready to sail. I also have a caldercraft model tug Joffre. Which is about 30" long and runs using a 6v monoperm motor and gearbox. 6v 4.5ah sla battery giving about 1 hour run time. Weight is 5kilos ready to sail. Hope this helps. Cheers Colin.
I already mentioned in another thread ("Any Clues") that three boats have been dumped in my workshop to see if I can find a buyer for any of them. 1) Caldercraft "Joffre" Tug, already built but in grave need of TLC with the propshaft tight and the rudder shaft too tight to move. The vessel is filthy dirty. 2) Billings "Le Pourquoi-pas", hull assembled with decks, remainder of kit & fittings look to be complete 3) Billings "Smit Nederland" Nr 528 - unstarted kit but does not have detail fittings I can post any of these boats and would appreciate a sensible offer for any of them - I do need the space to get on with my own work. Please PM me for any further information Regards Barry
Almost finished me WSPS47 now and find that I have the fire monitor pump here STR at this time. This item is totally unused and still in the sealed packing it arrived in. I have checked the (surprising) cost of this pump online and I am asking nowhere the advertised price, in fact, if anyone would like to purchase it or has any swaps I'd be glad to hear from them 73 de Bill
Westbourne is a Port of London Authority steam Tug from the Caldercraft Mini-Fleet Range - it is 1:48 scale. This model was discontinued a few years ago but I did manage to purchase a brand new boxed one via ebay a couple of years ago. During her time Westbourne was hired by the Royal Navy as a rescue tug. She saw service with them between October 1916 and July 1919 in the HM Dockyard. Prior to that she was on general towing service duties on the Thames. She can be found mentioned in “SHIPS OF THE ROYAL NAVY, 1914-1919 - by TYPE & CLASS Section 3. SUPPORT and HARBOUR VESSELS” Following the first world war ‘Westbourne’ was one of three tugs attached to the Port of London Authority (PLA) Dredging Service, they were the "Westbourne", "Thorney" and "Brent", they were all fitted with a drag and under running gear.In 1940 during the Battle of Britain. ‘Westbourne’ and many other tugs were used in assisting the berthing of these large ships that entered the Thames. The photos show from box to construction plus her on the water.
I am busy building the imara tug, caldercraft 1/3 scale on opening packets I found I was 6 pieces missing,these are the hatch windows with double pothole does anybody have any spare ones to sell or where I could purchase them
