6 lorry loads of type 1 were ferried in from the 'car park'.
The back end is now covered in track ballast, the foreground in type 1, with a second layer going on today.
The roller is for compressing the type 1.
Long shadows here; it's still early in the morning, but we are already well advanced.
Now back to the car park for another load....
|Dog lovers, eh?|
Dismount, stand by the side of the footpath.
A gift was left to us by two of the many dog walkers that use our permissive footpath.
After dismounting, and climbing back on board again, and dismounting again, 15 times a day, the day came when boot inevitably met dog mess. It was today...
After the jolly lunch, a quick peek into the loco shed found a Steam Dept. group busy riveting the first truss. You've seen the video, here are some stills with more detail:
The idea is to remove the temporary bolts that hold the assembly together, and one by one replace them with proper rivets.
Here a bolt is being removed. The bottom two are already done.
The bolt hole is tested with a cold rivet, and reamed out using the air powered drill where necessary (usually).
The rivets used are in two sizes - 5/8ths and 3/4 inch, depending on the job.
The truss on two trolleys is then rolled under the riveter, which is carefully lowered to just the right height. The business ends are changed according to the size of the rivet, here being tested, so that nothing goes wrong with a hot one.
On the signal, quick as a flash, the 'dentist' with a nasty looking pair of nips picks up the red hot rivet and inserts it into the hole.
You drop the rivet, it rolls around the floor. The 'dentist' picks it up again with the nips, and inserts it into the hole a second time. Drops it once more.
Now it's too late, it has to go back to the torch to be brought back to temperature.
It takes quite a bit of practice to get this right. With the lever on the right you can close the jaws and apply a mounting pressure on the hot, soft rivet. Right at the end of the squeeze, the pressure goes up to an impressive 40 tons.
This canopy isn't going to fall apart.
After doing the apex of the truss, the assembly is turned upside down and pushed back into the jaws of the riveter for the last row along the bottom.
It's Steve from the PWay pushing, so we all lend a hand. This sort of stuff unites us.
Outside, a few we did earlier. This is an impressive stack of assembled purlins, all rivetted and painted.
By the workshop doors, the final two trusses are ready for riveting. They were assembled at the beginning of the week. All the assembly work now looks to be complete; lots of riveting still to be done, and we are awaiting the arrival of the archged ridge purlins from a fabricator.
Back at Broadway north. Here is the opening view at the beginning of the day.
With no further ballasting yesterday afternoon, Steve took the opportunity to fetch more rail from Childswickham. As opportunities present themselves, he is building up a stockpile here, bit by bit.
Early this morning we received 6 x 20 ton loads of track ballast. Big Bertha was first to be filled, and in a low gear she crept up the access track to the top of the embankment
By lunch time, we had dealt with the 6 loads in the 'car park' and given Steve quite a bit of levelling to do. We are nearly at the station end of the stretch here; behind Steve is a long stretch of double trackbed ready for rails.
We were about to stop and do something else, when the cavalry arrived in the form of another lorry from the Forest of Dean.
The 360 digger was just scraping together a remainder, when more ballast arrived. Phew!
Broadly speaking, we have now completed the ballast excercise at Broadway north, there won't be any more dumper trips for a while and Big Bertha has been taken off hire.
We need to get more rails in, as the embankment behind this lorry is about to be closed off for the soil nailing excercise. This will take 3 months, and we will not be able to use the trackbed, or the 'car park'. We will busy ourselves with bringing the railhead nearer, more CWR welding and stressing, and if we run out of things to do, we might build us a buffer stop or two at Springfield Lane.
The arched ridge purlins have arrived:
Just to remind you, what is this arched ridge purlin, you can see one here in the original canopy at Toddington.
On the right is a truss, at the top a purlin, such as the ones in the pile painted green.
Remarkable, and rather beautiful, isn't it?
