[The Q]

If Anyone was planning to go to the Horning Boat show 2nd May 2020, It's been cancelled / Postponed to the 1st May 2021..for obvious reasons..

[The Q]

Not too much work was done this weekend , the nose of the keel was planed with the new planer  very good it is too, if a little heaver than the previous one.
Then the keel was glued and screwed together, so because that was setting no futher boat work was done..
Hopefully next week there will be less wind so I can get the marques covers back up which will then enable me to work on the rest of the boat, when not working on the keel...

Further Ivy removal from the garage was done, that meant the remains of facia came off..

Messers Bodgit and Run Garage builders extraordinaire struck again.. The wood above the window is made of no less than 7 pieces of wood. I'm picking up a new concrete lintle on the way home today, plastic facia boards and a few other bits and pieces. I want the stuff in, even if not used this next weekend, in case we get locked down and I can't go to work.

 I have by chance, a double glazed upvc window we cleared from a widows garage, it's just a little smaller than the current garage window that has a rotten wooden frame. So when the lintle is put in, up higher to replace the layers of wood, the new window wil be mounted tight underneath it, the space below bricked in..

Messers Bodgit and co , also Bu***erd up the roof, I noticed a line of light from the underside that shouldn't be there ( now revealed as I had cleaned that part of the roof). On inspection I dicovered this 4 ft piece of Asbestos corrugated roof had been cracked on installation..
 How do I know it was on installation? because all the others have their bolts in pairs.. This one, the bolt one end was offset onto the next intact ridge.. A repair has been done with a length of flashing tape to keep the water out.

Wooden lintels can be ok. My late Father's house has approx 4x3 lintels over internal doors, made from heavy pine that only seemed to exist in 1930.

I knocked down 2 non-structural walls and was very surprised to find the wooden lintels, but they survived 90 years.

[The Q]

If it was a single wooden lintle I'd agree but 7 layers of wood has allowed the wood worm to have a lots of meals.. Having an old orchard in  the garden, harbours the little blighters. so as I've mentioned before all wood I use gets sprayed with wood worm killer.
 But a wooden lintle here isn't worth the risk,  the concrete one is £12 so not too bad a hit on price..

[The Q]

As it turned out the new window was narrower than the space between the roof beams.  So I chopped out the half breeze blocks either side,  then bricked up to the beams and tying into the original wall.  That wall turned out to be just 2 inch thick breeze blocks.
 There is one more piece of rotten wood to be replaced between the next pair of roof beams,  that will be replaced by brick as it is everywhere else on the garage. The new window was inserted with two pieces of treated wood above the window.  One is cut to a wedge to match the roof slope.

As for the boat,  I'm still working on the wooden part of keel.  It's hanging from the roof with keel bolts fitted and foam inserted inside.  Today it will be hung up the other way and the second set of keel bolt holes will also have resin poured in to seal the threads.
 I'll also bring down the sheet foam today and make the blank double thickness foam block ready for carving to make the lead keel mould.
 

[The Q]

The wooden keel stub is almost complete,  both skins are on,  the inside is full of foam.  
The keel bolts are fixed into place, that's self locking nuts big penny washers,  and resin poured into the keelbolt holes through the wooden beams so there can be no water leaks.
Just the nose needs blending into the skins.

One that is done,  next a top load spreading plank that will become part of the hull and carve a male mould for for the lead lump on the bottom.

I really must take some pictures..

[The Q]

Can you see what it is yet?  Though more filling and sanding required.

[The Q]

Much of my time has been working on rather than in the garage.

However I have glued two pieces of polyisocyanurate together,  sanded them down into a bulging aerofoil bulb for the bottom of the keel.

 This morning glassfibred it, with 4 layers on the bottom, nose and tail , two layers on the sides.
When set I'll sand it down and put some more layers on .
Then the, fun of digging the foam out..


 

[The Q]

It's hardly a surprise,  but the 2020 3 Rivers Race,  has been officially  cancelled.

See you 5th 6th June 2021 for the 60th Race..



As for work on the boat the keel mould is progressing another couple of days and it should be ready to accept lead.

[The Q]

More fibre glass applied,  that was the easy but.
Digging the foam out wasn't, with only 4inch wide at most access at the top widening to 6 inches at most, many scratches to the hands occurred from the fibreglass.  

The moulding  was then measured for the bolt holes,  on measuring for the second set,  it didn't look right...

I'd forgotten to allow for the slope of the nose..  Remeasured,  marked up placed on keel without  drilling,  still 1/4 inch out.

  Rubbed off markings, measured again placed on keel looked OK,  went for Muggacoffee.

Remeasured placed on keel again,  still OK.  Sacrificed a new wood drill bit as they have a point to stop wandering.
 Holes drilled.... Keel moulding placed on keel,  bolt holes matched, slid down onto keel.  Moulding matched keel shape and position...  Much relieved.. 

At the moment I'm cutting sheets of lead to shape and dry laying them inside.  Once I've made them all, then I'll bond them in. I had hoped to cast the lead for better density,  but I've decided  the problems are not worth the effort for me.

Q,
Looking good so far. Reminds me of ballasting my old yacht with twin keels. I used steel billets and concrete. Laid everything out weighed every piece of steel and matched their position. Then dipped each one in red oxide - re-checked their position and weight. When the time came for filling each bilge keel I mixed up the concrete with Medusa and cast each keel and puddled. Interesting mix , do you mix dry and then add water or do you mix cement and then add additive? Once its mixed the whole is waterproof. Glassed over the top when finished. A very interesting exercise, took me all the summer holidays. The end result was sound. I hope yours goes well but you don't necessarily need lead.

(OK Don't know which roof they might have come off ...)

[The Q]

Sorry the face book reference comes up picture removed or link broken.

There has been a delay to boat building mostly because I've been doing too much in the garden.

I filled the keel with dry laid lead but it just wasn't heavy enough.  I couldn't get the lead to squeeze down flat enough to put more in.
So I emptied it out and when compressing  the lead with clamps got it down to about half the thickness.

So I've bitten the bullet and ordered a small lead melting pot which is due any day soon. It will take many melts to fill the keel.
I've laid a sheet of lead along the bottom, and one each side of the keel to take the heat.,  I'm going to then make loads of ingots,  ( cupcake trays for moulds) and lay a layer in the bottom.  Then pour lead between.  The repeat till the keel is filled.  That should give me the density of lead needed in the keel.

Twas someone in Gt Yarmouth with lots of lead for sale.

In Norfolk Broads Boat Jumble page.  (The link works but you have to log into Facebook first).

I quote "Lead Ingots
£38 – Gorleston-On-Sea, Norfolk, United Kingdom

These have been cast into high quality 15kg ingots, you will get very little waste as the dross has already been skimmed off.

As these are approximately 99% pure lead there is a great reduction in fumes and smoke, therefore you have a safer and cleaner working environment.

You save valuable time as you don't need to cut and prep old scrap as we have done that for you, all at a very reasonable price of £2.50 per kilo.

I have 27 of these in total but will sell individually." Unquote

So, while we are talking about lead, and with nothing but repeats and people zooming on telly, here's yet another chance to see the Great British HBBR Meltdown. Chris Peacock stokes up the forge to help Chris Waite turn a pile of scrap into ingots of pure err, lead.

 Thanks for the information,
The video is interesting,  the splashing is a good warning for protective gear. I'm hoping to get the keel made before the end of knockdown,  so my chance of getting access to a friendly forge owner is slim.

The electric melting pot I've ordered is due from today, should be here by Tuesday. Tracking shows it in the hands of Royal mail.

  I do have enough lead as I've been collecting it for years.   150kg is needed for the keel itself and maybe a bit more for correctors.  That's a fair lump of money at £ 2:50 a kg.

I'd not known about that facebook group,  I'll have to join.. I'm in several other broads groups,  though not a great contributor.

[The Q]

An hour or so after my last post,  the melting pot arrived.  Just the thing to play with in the cold tomorrow...

If any of the lead you are melting is in the form of pipes be very
careful about the orientation when melting it. I have had gobs of
molten lead erupt from a pipe, like a mortar, presumably because
something damp inside the pipe suddenly turned to steam.

[The Q]

It's mostly sheet lead from an old military battery servicing bay,  off of the work tops when they were scrapped.

[The Q]

When I finished clearing the Ivy off of the garage,  the last bit was over a lean to shed.  It became apparent it was about to fall down. So I helped it.
It's been replaced by a modified tin shed kit.  Picture below.  

The shed was moved back by about 4ft, the original was in line with the front of the garage.  All sorts of junk left by the previous owners,  was behind the old shed including ancient thin bricks,  bags of offcut  fibreglass insulation,  roof pitch tiles, many coils of fencing wire one large most small  and an ancient piece of twisted copper wire aerial,  complete with ceramic isolator on one end.
The moving back of the shed took much hard work digging and levelling.  Reducing boat building time as I was so knackered.

So today, as yesterday,  I will be cutting wooden floor panels for the new shed,  they go between the shed metal floor framework.  Meantime the lead pot will be melting more lead,  about 2/3rds of the lead  have been melted into the keel mould . I did 20kg yesterday.

Once the shed floor is finished my spare wood supplies will move from the garage to the shed,  that will give me room  to assemble keel ballast lump to the wooden stub keel in the garage.

My lock down has been cancelled by the company I work for, from 1st June they say they have enough social distancing processes in place.  So I shall hopefully complete the new shed,  finish the lead casting and assemble the keel  together by then.
