Bristol Barrow Road - Roundhouse Roof Trusses - Progress

It has been some while - June in fact - since I posted anything about the roundhouse. Since then I have had a closer look at the structure of the roof and realised that I had seriously under estimated the number of roof trusses required for the roof. Looking at an aerial photograph of the shed roof I plotted the 13 trusses and realised their positioning made no sense. This made me have another look at my collection of photographs and I have now calculated that the majority of the trusses are at 7ft 6in centres.

This gave me a grand total of 22 trusses for each of the three roof pitches or 66 in total. My first thought was unprintable!

 

Being a glutton for punishment I have plodded on making roof trusses - in between making up an S&D Sentinel kit - and recently achieved the grand total of 22 - time to assemble one of the roof pitches.

First stop was to make a suitable assembly jig on a piece of white melamine board and then solder the longditudinal purlins to each truss.

 

Here are some photos of progress:-

That is some serious engineering feat! Looks amazing...and only another 2 to do...class, pure class!

Very impressive work, Robin, and attention to quality. Some might even have taken the 'easy' way out and had them etched...

 

I agree with Mike, that is wonderful to behold!

Superb. It was clearly worth the effort - and something to think about when you do the next two :-)

 

The jig is very clever too - simple but effective.

Robin,

 

Good to see an update after quite a while. I agree wholeheartedly with the previous comments - you look to hqave achieved a wonderful structure. Have you tried it in situ on the shed building, yet?

I saw Liverpool Lime Street at the Warley Show, and your roof assembly reminds me of their rather magnificent station roof.

Good luck with the other two assemblies. This sort of stuff makes my efforts look rather mundane!

 

Cheers,

 

Dave.

Brilliant workmanship! The jigs are great and you've certainly got a lot of patience. The effort put in now is going to pay massive dividends in the end.

Hi Dave,

 

Not tried it on the shed building yet as the layout is dismantled. I will need to cut 22 new slots in the top of the side wall and fill the 13 laser etched ones when I get around to it.........

 

You're a bit further on with Delph - congratulations on running some locos on your layout.

 

Cheers,

 

Robin

That's incredible. And there are THREE like that? Plus the workshop roof?

 

It's nice to see this blog again.
