Missed some picks out of the music system.








Managed to attach everything bar speakers  under the table the gas tank valve slots in between.

Rather neat brass lamp housings there Jerry :-)) ......


We see many Navigation light Regulations [Sea going vessels 1940+] but is there a record of the same for River and Lake vessels [tonnage related?] for earlier time periods?

The main change that I’m aware of was the Merchant Shipping Act 1972 as amended. Where all collision regs  were incorporated with agreed standardised data for lights , filaments, colours and sounds. Frequencies of whistles in proportion to size of vessel. All very technical but before implementation red, white and greens came in many questionable hues!  The other thing was stopping peeps painting sidelight screens red and green and replacing with Matt black. This to sharpen up the cutoff angles of lights as red and green paint reflects the light outside required arcs. Similarly the filament in a navlight standardised as a single, vertical filament thus causing a point light source in the horizontal plane. As to river, canal and lake vessels, these are also covered but in general most small boats can pretty much manage with a decent torch. On the canals themselves in UK hireboats may not travel at night, private boats can and again only need to show a white light which is so they can see where they’re going. It’s rare to see boats moving on uk canals at night because you’re wasting valuable pub time! Incidentally, S L Canberra is post 1972.

I’ve been thinking about the steering gear hatch. It’s been sat on the boat but not secured so I came up with a wheel and strong-back system. A bit more brass work.

Looks the part and works. Next are the compass binnacle which has been living in the lathe chuck for 3 weeks while I waited for a new parting tool. Now on the lookout for a 20mm dia. button compass to put in it.





 I’ve searched everywhere for a decent searchlight of the correct size without success so out with the tinsnips again. I domed the rear by tapping the brass sheet with a small ball peen hammer on a piece of softwood. Bit of filing and wet and dry to remove tool marks then all soldered together. I was planning on making it swivel and tilt via a lever under the canopy but didn’t leave enough space between the lamp and the mount and couldn’t face  remaking it so it’s static.


So, just a life ring to make, it’ll be red and white because I’ve no international orange paint but I might find some reflective tape, then after we visit these two Indiginous Art exhibitions on Friday then I’ll hand the canopy over to daughter Sarah to work her magic. Inside the boat I need a ladder from gun whale to deck plates, connect up speakers ( when they arrive) and my work is done. She will need a strong box made up to protect her when we make the move from Canberra to Brisbane whenever that happens.
A few things to get for my lathe such as a milling attachment (I’ve got one in the UK which Nephew Ben might let me borrow back again plus BA tap and die set which is his). Then I’m looking at a new project to keep me off the streets. I’m considering a Stuart twin launch engine from castings or maybe a PM Research engine but got to work on the budget a bit.

Ok, on the home straight. Life ring made from four sheets of ply with grain alternating. I got about 20 little tins of Humbrol and Revelle enamel paint plus two plastic kits for free off Facebook market place. I’d forgotten how nice they are to work with and how long they take to dry. It’s faux reflective tape cut from one of those stickers you put behind car door handles to protect paint from scratches. I also found a source for lamp shades. Previously on the Wear build I used the tops of Actimel bottles but they don’t sell it in Oz so found something a bit more stylish. The tops off liquid baby food squeezy sachets. The canopy is with my artist daughter who is going to work her magic with dot painting Aboriginal style. I’ve asked her to sign under the canopy just in case she’s a future Van Dyke or something. I made a box to keep the boat safe for our move to Brisbane. Wife thinks I’m gong to do her in! Thinking about it.

Oh yes the 2” loudspeakers I ordered 3months ago didn’t arrive so I got a refund and got some locally (Jaycar). The system works but the volume set on the iPod Nano is very low and the volume switch on the headset doesn’t work so I need to borrow another headset to turn it up then all systems go. Steam testing awaits!

I’ve been laid low with a viscous cold for over a week now but ventured into th shed yesterday and realised I’d totally forgotten about making something to prevent the steam from the safety valve blowing the canopy off so I made this uptake fitting to cover the safety valve and divert steam up the pipe and through the canopy ridge. Also drilled four radial holes to divert steam horizontally as well which should prevent any restriction to escaping steam.

Looks nice,  but don't the radial holes defeat the purpose of directing the steam up the pipe?

The safety valve has 6 holes in it. This is enough such that when it lifts the pressure ceases to rise. Putting a tube onto it  is a restriction which might be enough to cause boiler pressure to continue rising after safety lifts. To be sure I’ve added the radial holes. This discharge sideways doesn’t compromise the security of the canopy.

Hi Jerry how do you adjust the blow off pressure?

I don’t John. It’s preset at 60psi. When I did the first steaming test it worked as designed. This boiler makes a lot of steam very quickly. Previously on Wear I reduced the psi setting on her safety but it became unreliable. The guy that made advised me to leave it on 60. I’ve got one spare bush so I can add another safety like steam locos have if it proves necessary.

The 20mm compass I ordered arrived so that’s boxed off.
 



I managed to find some scrap brass round bar 1.24” diameter which is near as dammit 32mm so that’s the chimbly cowl a press fit into the newly painted (satin black) Funnel.








The artwork on the canopy is coming on nicely.
