I finished off the remaining side of corrugated iron then cut the crusts (top edges) off the roasting tins. I glued and pinned two lengths of 6mm square section of balsa wood down the ridge and finished it off with the aforementioned crusts. I ironed on the vertical edging strip and trimmed it down. A little random battering and ageing to take the shine off and canopy is ready to fit.
I have hardwood 4mm dowel which I cut into 8 off 6” lengths. I rigged up a jig to hold the inverted canopy horizontal and level and offered the lot up to the bench drill and drilled 8 blind 5mm holes square to plane of the canopy around the edge. Into these holes I set 8 off 3/4” long sections of 5 mm brass tube secured with cyo. When dry I fitted in the 6” stanchions. Placed the whole lot on the deck and with cotton pulled the lower ends of the stanchions into the coaming, wiggled them into position so all vertical and marked the deck with the required positions of the lower stanchion chocks. On the lathe I turned up 8 off 3/4” wooden dowels with a 5mm hole through the centre to take brass tube. Will throw them at the sanding station tomorrow and grind each one down to size and fit them all into position. The canopy top is still a bit too shiny so a thin dusting off grey should tone it down some. Maybe a touch more rust and bird shite.
My eldest daughter is an accomplished artist and is quite into indigenous art types. She’s studying the Canberra style pics with a view to a bit of artwork on the top of the canopy. I favour those pics made up of paint dots. Who knows either way it’ll be different.

Bit of a production line today shaping  stanchion deck mounts, cutting and inserting brass tubes, staining and varnishing. Also stained the stanchions and rubbed the boat stand down with wire wool and put on the final coat of varnish.














All done freehand on the sanding station.

Canopy fitting completed, just a little adjustment to the stanchions required.

Had a good tidy up of the workshop and found some thin brass sheet. I’ve been looking for miniature Danforth anchors but they seem all to be a bit naive and cost more than a real one. There’s not a lot to them really so found one on EBay which had some dimensions in the pics. Captured the pic on my iPhone, expanded it to my scale and drew a plan. Marked the brass sheet with marker blue, put it under the plan and marked through with a Stanley blade. Cut out the parts with straight snips, bit of gentle hammering and fine filing before soldering. Only took an hour. What do you think?

I think it looks splendid Jerry.  Well done.  Looks like it will hold well!

Jerry that is a work of art. I can only imagine that you have very small fingers! Some jewelry chain will make it usable?  Very super work. :-))

Chain appears to be a bit of a problem scale wise. I t wouldn’t be studded on a boat like this and all the modelling outlets supply rubbish so cheapo jewellery shops seems the best option. I’ll know it when I see it. Actual assembly of the anchor is easy but needs planning and support. I only used soft solder and a pen type gas torch. Rest the parts to be soldered on a heat sink with supports/weights to hold the two parts used fine solder. Cut off the correct length, roll it straight and put it on the joint cold. Put the flame to one end and as soon as it puddles run the flame down the joint chasing the puddle. Only need one steady hand this way and easy to control. Then move on to another section using the first bit as a steady.

Hi Jerry.


Billing boats make 2- types of chain both in brass
F2.2 mm x 2 m

F327 1.6mm x 2m

I have used the 1.6 mm chain as rudder linkage , it has 12 links to 1 inch. it runs very freely thro' 5/32" copper pipe.

You can get it at. (https://www.cornwallmodelboats.co.uk/acatalog/billing_boats_chains.html ) or any Billings boat stockist.

First pic shown at 1"

Hope this helps.

George.

Thanks George, I did see that stuff but want 1/4 mile oval shaped links, however, if the joins in each link are soldered then I could soon make them oval. Are they? I only want 5”. Daughters going to go through her jewellery box in case anything suitable.
That hull is similar to mine which is 48” stempost to sternpost.
Anyway first I need a shackle, again nothing I liked on tinterweb so decided to make my own. Bit of scrap brass sheet, 1.5 mm drill and brass rod, tins nips and needle files and here we are.

Hi Jerry,
The links are soldered but it appears that you would want the 2.2 mm links which I don't have any.

That’s ok George. I’m not on the bum. If I can’t find anything I’ll make up my own.What’s the story on that double ender hull?

Hi Jerry,


The double ender is a TITANIC life boat made in Taiwan for display purposes only and as I had just finished machining a set of Reeves Marcher twin steam engine, so rather trying to explain it all to you here is a link to a forum that I use where I posted the build.


Have a read. (https://www.rcgroups.com/forums/showthread.php?2988006-Titanic-lifeboat-steam-conversion )


Have a read.

Today I’ve been working on a spurling pipe for the anchor cable. I needed to make a very tight bend in a 5mm o/d brass tube. This is what I think I’ll need





The bend is a small radius so can’t use my bending tool so it’s back to old fashioned methods. Heat up end of pipe and pinch the end.






Fill tube with salt, tamp  down well, heat end and pinch off. Heat centre and make a 90° bend using a 1/4” mandrel.





Cut out the bend and clear the salt out. Not perfect but I can recover it.
Turned a mounting plate on the lathe.








Went to Lincraft and found some 7mmx4mm straight oval chain from the jewellery making section. Exactly what I’ve been after and well made to boot. Next I made the slotted flap that closes off the spurling pipe and supports the chain. Too small to solder so used super glue.
Time to put some grey primer on anchor and chain. When completely covered I’ll finish the spurling pipe.
Jerry.

A couple of light coats of grey primer overnight and boxed off the anchor department.








 Then made an ensign staff socket  for the sternpost. Shows how I hold parts for soldering. In this case a 5mm length of s/s rod, a flat filed on the 6mm tube, paint on  Bakers fluid and place a length of 1 mm solder each side. Then run the solder down with the pencil torch.   








Tomorrow, the ensign staff.

Good job Jerry.  Nice metalwork and soldering.

And you know how annoying it is when some pedant picks you up on a trivial matter that really isn't a big deal?   >:-o   Well, grit your teeth because I reckon you have led your anchor chain the wrong way through the bushed hole before attaching it to the anchor.

Sorry.   :embarrassed:

Well spotted. I got it right first then took it off for paint. Must have been thinking about the next job. Fortunately the links aren’t soldered cos the shackle, chain in spurling pipe and anchor are permanently fixed. Cheers.

Then again I might leave it this way but glue note under the table so I can show it when someone else spots it.
