I used an old cooker hood as the basis for my spray booth with the filters taken out and vented outside, and has built in lights. I also use it as my silver solder/brazing and small welding jobs using the back wall as one side with simple hardboard sides and a rotary table (old party susan) if you can remember them, it works really well and allows spraying in my workshop in the winter months.
I have found as you have that gluing your abrasive paper to a wooden block is far better than wrapping and making sure all the bulkheads and other skin supports are at the correct angle can make a real difference to the line of the hull, only noticeable when looking down the length of the hull when painted and that's too late to change things. I also make a number of different shaped sanding blocks/sticks down to using the coffee sticks with abrasives stuck to then for getting into difficult areas.
Hi Mark - Steve? its Michael building the boat, the castings come in the kit from Vintage model works, there are two pieces to the tow hook and with some work can make a nice assembly for the boat. The scale is 1:12 all the best Michael
The white metal fitting has an awful lot of detail on it but lacks definition so some time spent on filling the body to better define the components. The anchor part has six hex dummy bolts cast into the base but I intend to drill these out and then use 8BA brass bolts to secure it to the woodwork. Looking at pictures of the assembly it is obvious that there is a handle arrangement missing so I made this from a piece of brass wire and epoxied in place. The two parts have a linkage to fasten them together so again using brass wire and a piece of scrap tube a linkage was made and holes drilled and tapped to secure the assembly. Finally, a couple of coats of primer followed by a “Gun Metal” finish and the items are finished. A pleasing result, however taking some time to do, now for the circular running rail, and supporting posts to complete this unit. Michael T
Thats coming on nicely and as you say it looks quite a rigid construction. How much of a bonus is a lightweight construction V an all ply construction as I assume you may have to put some ballast in the finished model. not thtat I have any experience on the subject
Now Plank on frame really sets my imagination going, I have to say that i am a builder rather than a sailor and get immense pleasure from problem solving and just creating structures. I will be looking for a suitable subject after the Crash Tender which at the moment is taking some time with fiddly bits that don't seem to advance the the overall vision of the project so apologies for the lack of "blog" Any suggestions?
Hope this helps I no expert but wikipedia explains it. Standing rigging on a fore-and-aft rigged sailboat. Key: 1. Forestay 2. Shroud 3. (Spreaders) 4. Backstay 5. Inner forestay 6. Sidestay 7. (Boom) 8. Running backstays
This is a small item but very visible on the wheelhouse and since the standard for this item has been set I have to follow suit. So first of all get some 3mm blue LEDs ordered and then it’s on with preparing the white metal body. I used by hand as suggested a series of drills increasing in diameter until 3.1 dia was reached but only 2/3 down the length from the front the smaller hole (1.5mm) was bored right through for the wires to exit. Arrival of the LEDs, first check the LED using my power supply, just over 3 volts seems to illuminate to the correct level. Next was to remove the shoulder on its plastic casing so the whole body does not exceed 3mm over its length and lightly abrade the outside to give a diffused light. Next cut the LED legs to 2mm from the plastic casing noting which is positive, next prepare the wires. I used Futaba servo wire cable 22awg which is very flexible and with the white signal wire stripped off leaving a red and black wire. These were tinned and cropped to 2mm and then quickly soldered to the appropriate terminal. Next check the LED still works! first hurdle over, I now needed to check the that when the LED goes into the body it doesn’t short out so checking the diameter over the widest part which is over the soldered terminals this was 0.1 below 3mm. I decided that shrink sleeve was too thick so I mixed some epoxy resin and coated all around the terminals, this proved to be satisfactory in both non-conductivity and dimensionally. Now the final test, using some aliphatic wood glue I slid the LED into the body whilst it was illuminated as it was a tight push fit, bingo it’s still lit – leave to set. I used aliphatic glue, as it would be easier to remove should I ever have to change the LED. The body still needs painting white but this will be done with all the other fittings at a later stage.
This is simply a revolving drill chuck.it doesn't have any longitudinal or cross feed travelling tool post and at best its only good for wood turning of very small diameter pieces of wood or polishing small parts. I don't think it suits your requirements. Colin you beat me to it by 60 seconds
Come on Rob give me a break I have nowhere near finished the Crash tender yet and the Freeman cabin cruiser, not sure I can tell my good lady that this is the next project Ill give it a month or two The launch looks great I look forward to some detailed instructions to follow
Adhesives are a combination of Epoxy for the structural joints and aliphatic for non structural joints unless the type of material is an issue eg white metal fittings adhered to wood would be epoxy and canopy glue for transparent components.
Photographic point taken, problem is that I take a picture and by the time I do the write up for the blog the item is either assembled or the set-up dismantled and its too late to go back to take a better shot. However I will have to try and edit at the time of taking in future.
A working search light seems to be expected on this craft so here goes. Based on Robs build I purchased the lens and the LED from Maplin’s which seemed to fit the bill. The only piece that will be used is the main body that is supplied as a white metal fitting, the rest will be replaced by a brass construction, as the rest of the parts are not substantial enough to support a working unit. First, I need some 3/16 half round brass bar, the easiest way is to machine my own cutting just less than half the diameter away. The half-round bar was annealed before bending round a suitable mandrel to a half circle. I then soldered an 8BA nut on each leg to act as the swivel bearing. Next, I machined the body’s internal bore to suit the lens body and skimmed the outer rim and face, finally bore out a small recess that locates the lens in place. The two pivot holes need to be drilled and tapped 8BA, and then a drilled hole in the rear wall for the wires to exit. As the light is to be both working and rotating the base has is to be made with a centre spindle that connects to a micro servo under the roof. The connecting devise was a bit of a headache trying to make it fit in a relatively small space; I used the supplied servo arm with four legs (shortened) and then machined a mating part with pins that located in the arm that is attached to the body above deck. The LED was modified to fit in the white metal body as it has a heat sink which was too big; as others have found cutting it down didn’t affect the heat dissipation when fixed in the white metal body, this was fixed using a small amount of Milliput. Having already machined the outer flange on the body I turned up a brass-flanged ring to push fit on the body this has to have the TRI form guard added. I made this from a central pinion with three holes drilled to accept the bent brass nails; these were soft soldered in position. The TRI form was then located on top of the brass flange and again soft soldered in position At this point all the components will have to be dismantled for final finishing before being painting.
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
Rear cabin hatches I have decided to make these two roof hatches detachable (not working) purely to ease the painting and rubbing down process. The hatches on the rear cabin are supplied in pieces to be glued together, so to make them detachable I drilled a hole through the base of each and glued an 8BA screw in place, these can then be secured after final painting to the roof. The hatch also has a dummy-hinged lid and small white metal hinges are supplied, however they do need some attention, such as drilling all the holes and trimming the edges. Here we go again, time for a jig! Repartition can be achieved with the simplest of jigs; all I used was coffee stirrers pinned to a block of wood and one as a locking device. The jig was then placed under the milling machine and the first hole centred, drilled and then the next hinge is placed in the jig and drilled and so on, move to the next hole until all holes are drilled. Before fitting the hinges there needs to be a separation line for the lid and hinge plate so a scored line about halfway through the ply. The hinges are fitted with epoxy and brass pins through all the fixing holes. Mid cabin hatch This is a single hatch, again a square of ply is supplied, but this is improved by adding sides, which can locate on runners, again the runners are not supplied. This hatch is also attached with a single screw epoxied into the top and a nut, after final painting. Forward cabin hatch Again, a single hatch and dealt with in the same way as the mid hatch.
I assumed you were on holiday Doug, however hope your feeling better because there are questions to be answered and problems to be solved and inspiration to be shared!!!! finish that sausage and get on with it 😁 all the best Michael
Not sure your correct when you say ply doesn't bend in two directions. when building my crash tender the roof panels are a compound curve, I steamed them and let them set in a jig. I agree this will be somewhat more difficult when dealing with a full length skin but with some thought and appropriate jigs and clamps I think it can be done. Ill give it a go on my next build.
