The crew assembling the new Broadway canopy were very kind to demonstrate the use of the riveter today.
The rivet is heated to a red hot temperature until it sparkles.
A gas burner was used today, as we only did the one rivet for demonstration purposes.
Once the rivet is red hot, an agreed ballet takes place whereby the man on the gas burner steps smartly over to the operating lever on the riveter, being careful not to cross the path of his mate, who is holding the hot rivet to be inserted into the hole without undue delay.
You can see how this is done in the following video:
Making good use of the sunshine today, after yesterday's washout rather hampered the planned assembly work, the team of two continued on the manufacture of the four remaining trusses (out of a total of 7). Here are three of them outside the workshop, with work well advanced. Before doing any assembly work, a kit of parts has to be prepared first. This stage is already complete.
With the good weather today, work could advance on the first of the next batch of trusses.
One from the first batch of three has been put on trestles outside, and the next one to be assembled has been laid over the top.
Here the other end of it is tacked welded into position.
Once all the pieces have been tacked together, they are drilled and bolted togther with temporay bolts. The final process then is to remove the bolts one by one, and to replace them with rivets.
The intermediate struts have already been cut to size, but often need a bit of fettling at the assembly stage to get them to fit perfectly.
In this overview, the new truss is almost complete. All the holes then have to be drilled for the bolts and then rivets.
The intermediate, arched purlins are being made by an outside contractor. We have the capability to do this, but chose the contractor as this saves time.
The steelwork could be finished in a month - don't quote the blog on this, things can get in the way - and then a trial assembly will be done in the car park. Next to testing the structure, the prior assembly also allows you to drill the final holes that will be needed when it all fits togther on its frame at Broadway.
All this is being supported by the share issue. It should look fabulous, and will be something we will be proud of and look back on with pride in future years.
