Hang on its not the last small noggin thats the prob.. as I get access to fix it however small, via the outside/ 400mm gap. So its getting access to the last-but-one normal nog.. within the small gap. Unless I train a chimp with chimp small nail & hammer to get in there I cant fix it. Or am I the chimp? who the fk is teaching who here?

But I cant get access to put in the noggin, if I ve got a small gap left over.. this is why I'm trying to get them even. Apart from brain cells, am I missing s'thing?

Very good point! understood.

Another Q soory. I 'm having trouble working out my 5x joist spacing. I just can't work it out to mean the 5 are equally spaced in my 2170mm gap. If I divide 2170 by 5.. this doesn't work. Or by 6.. doesn't work. What on earth am i doing wrong?

Or same galvanised.. that means non-rust I think/ surely I need for rain exposed posts.. or not matter then? boring Q sorry!

These I assume.. I'll have most left over/ so these ok for exterior jobs too, eg into softwood posts/ steps/ gdn walkway etc? https://www.screwfix.com/p/easyfix-round-wire-bright-nails-4-5-x-100mm-1kg-pack/16534?kpid=16534&ds_kid=92700048793290424&ds_rl=1249413&gclid=EAIaIQobChMImrKOtP625QIVBMjeCh2YOAg1EAQYASABEgKvgvD_BwE&gclsrc=aw.ds

Gotcha! blimey that one fried -my noggin- 1st thing.. was about to go buy 10x more hangers/ £20 saved. Any special nails tho? my twisty hanger ones too short.

Will I have enough room to get a hammer @ my nogs tho? so I got 380mm, take off 50mm for joist W.. is why I was thinking isn't it made easier by putting nog hangers on joists after joists cut to size, but not fixed in themselves yet. I'm trying to figure out why staggering makes it easier to fit nogs too.

Is the reason you're suggesting 400mm, bc I mentioned I was celotex'ing & that figure suits it-?

@PeterW oh & when I mark at 400, 800.. is this mark the front edge of the joist, or the centrepoint of it?

Cheers- frame alone taken me a solid week work tho.. 1 morning for you guys! bad day y'day but vgood today. I'm 1/4" out across the diagonals, & its all solid, so I'm chuffed. Ok so if I measure 400 from outside (back) frame edge.. I'll have -one- odd space of ~240mm. When you say -two- are you dividing this last odd 240mm into two, bc of the noggin to go in mid of it?

Ok Ive heard the 400 figure said before.. but where is it best to measure this innitially from? the inside of the back beam (joists will go parralel to this, perp to stream).. or the centrepoint of this beam? I have 5x joists to go in this 2170mm square, so not sure how best to position them you see. I'm putting celotex in between, & a centreline of noggins (not staggered- I don't think it needs it-?). Thanks- yes I'm a lucky sod finding this little patch of paradise!

@Onoff @Declan52 @PeterW .. I need to do my 6x2 joists asap, so if you could help on what figure to space them at (I have 2170mm to span).. thanks alot chaps.

I have a distance of 217cm to span both ways. Is it 400mm centre marks or something, or is that figure for pB?

@Declan52 or @PeterW or @Onoff Done my outer frame at last.. & I'm onto my joists. What distance between joists across would you suggest? if I have the hanger brackets, & I need to add a centre noggin, I need to get a hammer in between joists to fix the brackets. Or is the idea fix the centre noggin brackets (I assume noggins don't need to be staggered) onto the joists, one each side of the middle, before joists are lowered into place-? Thanks. Pics of it when time.. rush on b4 the rain hits t'nite for 2 days.

Well that's some reasurrance- but honestly the way the wind fires sideways at my extention end sat like a sitting duck, but on past into the channel my garden's in.. end of it the cabin, another sitting duck (with overhang roof facing it all).. it just has to be overengineered, by a heap. Maybe I can use that bolt with a new nut on.. if it sticks again I'll leave it. Is the angle grinder ok to trim off the burrs with, on the top of the cut bolt? seemed ok for t'others.. but filing by hand is a pig of a job.

Oh yes the nut/ bolt both totally shot.. its really not important vs the fact that it just turned. I hope you're right & at least my others are ok.. but it doesn't give me confidence/ stresses me out that they're all compromised. Maybe I can drill some extra holes in the shoe base, & put 4x thunderbolts in each shoe too. Washers for risers is a good idea.. thx.

But more important is your view on the resin job I did: if this sod stuck nut-on-bolt/ the whole thing twisted round by muggins trying to force the nut on with spanner.. would you expect the resin to be so rock solid Id not be able to push spanner round at all, or, is the fact it shifted signify all my resin job is perhaps n/g?

Somewhat of a disaster- resin went in ok but cleaning the holes before was almost impossible I found.. tho did my best (5 hours cleaning them ny'day & today) so my hole depth decreaced from 9.5cm to ~ 6cm & so bar protruding/ needed cutting off (as impossible to drill a perfectly vertical hole) > deburring with angle grinder > one nut stuck solid > bar shifted in resin trying to undo it, or force it down. A mare of a day.

@PeterW I wish i had this post before I did it. I dont get the plates on tho/ you've no way of wiping off excess with plate on, & excess will bond to plate. Ive done it before your post, but came seriously unstuck & unsure about the whole job as a result. The cure time info @ 60mins is maybe inept: I put nuts on & went for a dry run of tightening up one pillar/ shoe. This went ok, after i enlarged all 4x shoe holes to 13mm, it went on. Onto the 2nd pillar, holes enlarged. 3 nuts went on ok (de-burred with angle grinder, I cut the big bolt 5cm excess off 1st you see to help get shoe on.. which I hadn't accounted for so high: something went wrong with the holes depth). But the last sodding nut got stuck on the thread, & stupidly I forced it, but it was super solid stuck.. so I continued with the spanner fingers x'd.. & the damn whole bolt started turning in the resin. Buggered. Ok so i cut this sodding nut off/ this bolt unuseable. I don't know if it was the resin A) not cured B) not fixed properly due to dust/ debris in hole or C) you wouldn't expect the resin to cope with such pressure anyway if a stuck firm nut is forced down / the bar forced around with a spanner. What do you think?

yup. if I had on of these. Id have used it.. job's done, but Ive no idea if its ok, only just good enough or a useless bond. only time & a storm will tell.. not exactly ideal.

This stuff apparantly cures in 11-20*C in 60mins.. is that right? that means I can whack on nuts/ anglegrind the bars etc.. in an hour?

yup. if I had a compressed air thing. Id no doubt have used it too..

I did this countless times with every drill/ extracted the most I could. Then got a vac on, then a brush, vac again, then a fine pick on btm, brush, then blew each very hard with bellows, brush probably 8-10 times each, blew out: I must have spent 1/2 hr cleaning every one. I thought I had them ok, as dust got less & less to very little coming out.. but now I must have just compacted alot of loose stuff down. I mean the brush itself cannot extract stuff at the btm, it only contacts with the sides, so you need some form of suction device.. &v a vac was mentioned, so I went way ott on brush/ vac as best I could do.. it seems an impossible situation to get the debris out.

So look you see I had so much strife with soudal foam + gun, its how you use the nozzle, like how/ when to take off the gun/ how to clean (still no idea).. I mean one false move/ you take off the wriong thing & the lot sets, & you waste expensive stuff & possibly screw up in middle of a job.
