This drill bit would be ideal for your needs. https://www.screwfix.com/p/bosch-expert-straight-shank-multipurpose-drill-bit-14-x-250mm/549KY? First off top brand. It'll drill timber and masonry too (metal even if you hit mesh between courses etc). You could prop your ledger up level on some other bits of timber then drill through the timber into the wall. Use insulating tape on the drill bit to gauge the depth.

I'm just about to sort my masonry bits. Might have a spare 14mm or two.

All posted just now via Evri. 1.5kg box wrapped in olive green duct tape. Fyi: 10mm drill for M8 studs 12mm drill for M10 studs 14mm drill for M12 studs

8bar here. PRV fitted. You do have to occasionally clean the mesh filter in the PRV. I think too, MIs say to fit the PRV in a horizontal section of pipework. I didn't...as I didn't really read the manufacturer's instructions properly...

The pump, expansion vessel and control gear I bought on Gumtree is sat up in Willowbrae still awaiting collection. Was supposed to be by a Scots mate who lives down here. He's decided now though that fuel is too expensive to drive up now so he'll be coaching it. However, the kind chap holding it for me up there is now packaging it all up for a courier. I do though now have a wasps nest to get rid of right where I need to access to do the panels!

You will also need a 14mm masonry drill bit thinking about it. Something like this: https://www.wickes.co.uk/Wickes-Masonry-Drill-Bit---14-x-150mm/p/168043 I'm guessing you don't have an SDS drill?

All boxed up. I'll get them on Evri in the next couple of days. As well as the fixings is a chewing gum pot full of copper anti seize paste. Double bagged etc.

I've seen a few instances where AC rated isolators (as in good for 3P) have been used on DC battery systems. People wonder why they burn out 😂

I've just some A4 Fischer ones, photographed above somewhere, think they're only 160mm. Saying that I want to keep them for when I make steel framed infills either side of the gate pillars.

You will I think need some stainless steel studding, A2 grade. It comes in 1m lengths. I reckon you'll just get away with cutting into 5 nom 200mm lengths. Cut with a hacksaw or slitting disc in a 115mm grinder. Ideally then buff the ends/de-burr with a flap disc (in the grinder). https://www.toolstation.com/stainless-steel-threaded-bar/p37920? Your drilled holes, in the block, need to be properly cleaned out. 80mm depth is a little on the short side for M12 stud. Rough calculation for the stud length: Drilled hole = 80mm Spacer = 50mm Square washer = 5mm Ledger = 45mm Washer = 2mm Spring washer = 3mm M12 full nut = 10mm Thread projection = 5mm Adds up to 200mm

Nice to see positive discrimination at work on that link...not! Where all da white women at?

To be fair he gets loads of help & advice on here etc. Done I think...I can cut a couple more tubes to make 10 of everything.

I think @Binky is the @Binky from the electrician's forum that @ProDaveand I know from there. I think I pointed him at this forum but can't remember. Something happened with my account at TEF and I couldn't get back in. Not been on there for months.

I'm not a scheme member and tbh only dabble. I know absolutely jack about solar either. Would @Binky know of someone this neck of the woods?

Need to get my own little lathe up and running. I did make some headway this week and uncovered it at least. Slight problem is it's stored vertical.

Evening @zoothorn Right I've drilled the 30x5 stainless flat bar at 14mm and started cutting the square washers. Sod's law I think the cutting compound is causing the bandsaw blade to slip. Truth be told I've had a couple so am giving up for tonight. Basically you'll get these: I'll tell you know the hole won't be dead centre like this in all of them! This is what you get when you don't employ a professional! These square washers btw are from grade A4/316 stainless what you use for maritime applications. They won't corrode unless you I don't know over heat it or something. As in its good stuff. Tbh I'd have preferred to make them 50x50 but beggars can't be choosers so they're 30x30. In use then the stud will project out of the spacer and there'll be a square washer on the end of the spacer, between it and the ledger. Mocked up like this: The other side, the front of a ledger then again you ideally want a large diameter washer to spread the load. Here you could afford to use galvanised or even bright zinc plated ones for now. You can buy M12 square washers easily enough. Worst case if they rust you can change them later. The thing is that at the front of the ledger you can access it. I'll chuck in some large form zinc washers for the front, it'll get you going. So here it goes big washer, spring washer, full nut: Ideally you want "3 threads" projecting from the nut so about 5mm but as it's wood, I'd go 10mm. Leave your M12 studding over length and cut off later. We'll discuss how razor sharp the ends of cut studding can be another time, along with how to address it.

Such a shame this, I was due to come over to the IoW last week and could have brought my lengths of Unistrut and £29.99 laser level! 😂 (Was coming over seriously but cancelled due to father's ill health then my lot got Covid the week we'd have been there).

My slab was that flat with my diy screed rails it didn't need SLC. Most people other than some on here wouldn't take the time to do what I did. I'd hazard the majority of bought in contractors certainly wouldn't.

I could lose that on my plot no problem.

Right, stainless tubes cut. I'd cut slightly over length with the intent of turning them dead square on the BiLs lathe. Then realised we're a Covid household at the mo so probably not very sensible to go over to his place. Thus I've cut them on the bandsaw, dressed the ends with a flap disc and gotten rid of the internal burr as best as with a countersunk bit. They are square enough for whet you're doing. Length is 48/49mm. Shown on an M12 stud: Then I've sorted 20 flat round washers, 10 spring washers and 10 full nuts. All stainless but a mix of A2 and A4 grade. I'll try and remember to give you a small tub of anti seize paste. Messy stuff you smear on the stainless stud itself or inside the nut, that stops it locking up. Stainless, especially low grade A2 is notorious for it (locking up) if using nyloc nuts. No nylocs here, instead use a full nut and spring washer. Shown here on a genuine, M12, resin anchor stud. Has the hex drive one end and chisel point the other. For what you're doing just use stainless studding, cut to length. Anti seize paste is belt and braces. I'd have carried on and cut the square washers but it was making SWMBO's post Covid headache worse. I'll try and cut the square washers tomorrow.

Less inter seasonal but more out of hours but there were some projects over in the now defunct US solar forum (can't remember the name but a "Gary" ran it). A few people were using bfo, homemade ST panels to heat large, insulated volumes of sand or I think gravel under their house or in their basement. They then released this overnight i.e when the Sun wasn't shining.

Mine do, well on here anyway.

Haven't forgotten about this. The tubes should be quick to cut, might do them in a mo after a coffee. The square stainless, plate washers, a bit longer. The sooner I start I suppose! Standard M12 washers, just a case of digging them out. So spacers at 45mm for definite?
