hmmmmn.that bell transformer needs taking out st b;its costing you money!!! try wiring a waterpoof bell push (mk master seal) into the mains side,with the transformer secondary permanently connected to the bell;or let em knock on the door!
Hi NI yes I am well aware of the transformer. It burns up c 9W which works out at about a tenner per year! Given my PC runs at 15W it's a disgrace. Not sure if bell wire is up to mains voltage though. Do standard bells work on DC? A battery system may be better. The house is fairly big and the bell does help though I have a large knocker on my front door. The bell is on the to do list! StB |

You should get Rick's number off Mike and find out where he is politely. Ask him when you see him if he has been up to Inverness recently as Mike reckons they haven't done a run up there since June!!!! grrrr!
SteveK is looking after my order - not sure how the work load is distributed an Navi' HQ. He said he would call the driver and get back to me sadly this probably won't now be till tomorrow. Edit: (11am 20th Aug) SteveK has now gotten back to me apparently the order wasn't put in the van! He is now trying to make alternative arrangements to get it to me on Friday. If not the StBC PV weekend will have to be postponed yet once again. StB |

Well strut arrived at c 2:15pm. (Tony said that he spent two hours getting a roof rack in the van). Nice stuff but made short work of my hacksaws - would have thought Aly would be much kinder than steel but apparently not. The drills on the other hand cut it like a dream.
The back wrench I was hoping to use to connect the vertical and horizontal strut is a bit too wide so will need to think through what I need.
Have purchased two new power hacksaw-blades (Bosch S123XF), I hope they survive the weekend! Anyway first bit of strut in place (though needs to be loosened a bit to get the vertical sections in.

"Have purchased two new power hacksaw-blades"
Sorry, an aside:
I have been taking some timber buildings down (sheds and the like) and cutting through the nails / screws that held them together with a reciprocating saw.
I've got all the blades that Bosch make for them. The combined Wood/Metal blade does a fantastic job, but is pants when it comes to screws.
So I bought Basic metal blades. Also pants. Then I bought the maximum TPI metal blades. Also pants. What gives?
I've been using minimal pressure, but the saw "reciprocates" like the clappers (Panasonic)
In the end I have resorted to driving a wedge between the timbers to create some space, and then using a 9" angle grinder. Now THAT goes through them like the proverbial knife + butter.

@Sean - use paraffin or similar as a lubricant when cutting ally.
@ kristen - slow down. Screws are very hard, use a squirt of wd40 at least, lots of pressure (relativly) and slow(er) cut speed.

Ah, OK, I'll remember that, thanks. My Panasonic doesn't have variable speed, but lightly squeezing the trigger will give a slow speed - if I don''t get cramp!

As Guy says you need a cutting lubricant for Alli... mainly to stop it sticking to the blade & filling the teeth. Parafin is the best lubricant for machining alli but a bit thin, I just dip my saw blade in car engine oil... works fine.

The frame work looks impressive And excessive. Wont the two horizontal members catch leaves & muck & then cause a back up of water leading to damp? |

A big thank you to all who has helped with advice on the StBC PV system and more particularly those who turned up on the day. Indeed as it panned out the only forum member was Stuart to whom the greatest thanks go. Also deserving of special mention in dispatches are Omar who came all the way from Sheffield and David who did too much lifting on the first day.
I am now going to embarrass Suart but if you can get him take him!
Turned up with a set of professional tools which proved most valuable on the job
Worked like a trooper both days and till 9:30pm sunday
Was able to make up the PV cable connectors when others had given up
Is part P registered and happy to sign the paperwork off. Must be worth an applaud each that lot!
Despite everyones strenuous efforts a weekend proved too little time to install the system. Will add some more thoughts on this later but here is an attached photo of the current state of play......

Kristen thanks Justme, I can understand your concern re fill up with leaves given your location. The horizontal struts are however above the roof by a good 2.5cm so I am hoping that that will be sufficient. Over the years also I have become used to where leaves tend to pile up in autumn and it is at the other side of the chapel. I never have had any significant leaf build up on the south side when I do my annual gutter cleaning. The north side however is a different matter. Regarding excessive framework it is largely to do with the way the PV is bolted to the frame. Each PV panel is connected to two vertical struts. As there are 7 columns of PV this means 14 vertical struts. The horizontal strut is the minimum I can get away with, though I agree it does look over-engineered. |

The more I see roofs with PV and Solar Thermal the more I think the slates are a waste of time & money ...
