I have reached an age where the sun is not my friend. I'd rather get up at 0500 and do whatever needs doing outside then. I've had a few bits of skin chopped off already, nothing serious, I took those as a warning. If I need to be outside in direct sun I dress Thai style with long sleeves and trousers.
^My case either, in Thailand so easy to get it cut off. However - in defiance of doctor's strong warning - I am still refusing being mummified while cleaning swimming pool and while swimming.

Oh dear, I took your "frame" as the shore to post, support structure not, as you show above, the shore concrete pad reinforcement.
It's a question of where/how it is placed and its loading.
Mendip, whatever you are using to span between the shore pad and the two pond posts.
I suggest, you place the beams/ finished assembly, prior to installing/welding, on some bricks, load it at the centre with 3 x your weight + a large fish , stand on it and wiggle the assembly sideways.
If it's still standing OK, If not add more cross and longitudinal X braces.
Repeat until there are no deflections, vertically or sideways.

A tray full of GOLD is not worth a moment in time.
Yeah, exactly right Shutree.
I'm a complete twat to be doing this stuff... I've had one bit cut off me at Bumrungrad - it wasn't bad but should serve as a warning.
But how to dress Thai style? I'm swamped in sweat doing this stuff and a soaking wet shirt is so uncomfortable. I've started wearing shorts now but much prefer to work in just underwear. To be honest stark bollock naked would be the way to go but I think the gardener would stop helping me.
After a later than anticipated start yesterday I decided to measure up and cut the metal to length for the jetty frame. At least I could do this in the shade.
The very first cut shredded the grinder disc
Sadly I had no spare so this meant a tortuous visit to Do Home.
When I arrived at Do Home I realised that I'd forgotten to bring the old disc... which would have made the whole process a whole lot easier. So instead of just showing one of the hordes of assistants standing around what I needed... I had to mime using a grinder. As I'd expected, the first 'assistant' sent me in one direction, until I gave up looking and then another assistant I waylaid sent me in an other direction. I think they call it 'farang pinball' and before now I've been sent in 3 or 4 directions by as many assistants until finally losing it with the last assistant to point to yet another part of the shop... and told her she could keep my fukkin fully laden trolley and stomped off. I was the loser of course because I had to do all the shopping again at another place.
Anyway, yesterday there was no such problem and an hour later I was back in business. I even found an old bit of 3 by 1 which will come in handy later.
And the finished frame.
I was hoping to get the insides of each metal 4 by 2 painted and so ready for welding, but I ran out of time before having to leave again to pick up the daughter from school.
There's just enough metal left to make a small fence kind of thing at the seaward end to lean on while having a Leo.

Nice Job Mendy,
While you may not think its a valuable tool, I would invest in one of those cutoff saws. I bought a Bosch off Lazada for a job I was doing before the pool projected started. It paid huge dividends when doing the frame for the pool as my Uncle had his, and I had mine. I never thought I would use it much but I use it a lot. I bought it during the Lazada sale date deal, was like 2500 baht. Its far safer plus your cuts are square so welding is easier.
^ Yeah, no problem with two of us.
The first lift will be onto some bricks so I can do a bit of load testing.
A rare compliment ootai... you have obviously noticed that I just carry a few extra pounds... soon to be gone by the way.
It's been quiet on the jetty front today... the daughter seemed to have a day off school so I wanted to do stuff with her, but I did get a few odds and ends done.
I wanted to check the pond temperature with the pool thermometer duck, and when I got there noticed that the gardener has been busy. He's obviously resigned himself to doing the offshore welding and has rigged up a kind of support using a piece of scaffold tower. I guess if it all goes wrong I may lose a gardener but at least I'll find out if electrofishing has a future.
While Tommy tried to catch the duck I placed down a couple of L-pieces, shoreside, to help welding the frame to the protruding rebar. I fabricated these this morning... all of these small jobs need doing and take an hour or so to do, here and there.
This put me in the mood for doing something else so I took away the shuttering. Not a bad job at all!
So, the status at the of about day 11? If I can get the inside of the metal painted tomorrow then welding should be on for next Monday. I try and leave the weekends free for daughter orientated stuff.
When complete an online
is compulsory.
An inspection of all welds, shore pad and at least 4 people on the jetty would confirm your status as a marine engineer par excellence.
A fish, chips and peas dinner competition, on the day, can allow our virtual chefs a chance to show their skills. Suitable wines can also be suggested.
The HSE-approved offshore welding platform is finished... or of course the electrofishing platform, depending on how things work out.
But today's main task was to put a coat of primer on the inside of the metal beams.
Ootai suggested this... he may be an engineer and an Aussie to boot, but he seems to talk some sense. This made even more sense today after I read elsewhere on the forum that I can look forward to an active sex life in my seventies... I don't want to be wasting time doing jetty maintenance in the future when I could be enjoying myself. This structure will be built to last.
This was a two man job and achieved by putting one end of the metal into a primer tin and pouring primer through the beam, into the tin. Once this was done for all four internal faces the metal beam was turned around and the process repeated from the other end.
It was a little messy but the job went well. We thinned the primer down a bit to help the pour.
And the finished beams... once dry, all ready for welding together.
I also cut the remaining metal to make the end fence bit. After walking around the garden testing various heights for leaning against, I settled on 118 cm as the perfect height to lean against, beer in hand, while staring at the pond. Therefore two uprights were cut at 113 cm, thus allowing for an additional 5 cm for the cross beam - such is the level of planning that would make even JPPR proud.
The old bit of 3 x 1 was cut with 45 degree ends to make two diagonal supports for the end fence, to help it take my leaning weight. I worked out the length of these diagonal supports using nothing more than Pythagorus - so it'll be interesting to see how good these ancient Greeks really were.
12796 is that the correct figure? If so I get a different answer..
^ You got me worried because I've cut the metal now... but I've just checked and I think it's good.
113 squared = 12796
12796 + 12796 = 25538
Square route of 25538 = 159.8 cm
Or 160 cm for luck!
At least, I hope that's correct...
Aah... shit.
AO, you are perfectly correct.
12796 x 2 = 25592.
My calculator must be playing up.
But as luck would have it, the square route of 25592 is 159.97.
Therefore, my rounding to 160 cm is even more accurate than when using my previous answer of 159.8.
Wow... that was lucky!
I gotta say Mendy, that brought a tear to my eye.....
^See we think alike KW. Its all about the details which shows it was well thought out. Those usually get someone saying " Nice touch, I would have never thought about that"..
Almost beer 30 Mendy. I just ran to Topps and picked me up a variety beers to pull up a chair too. I was pushing the cart around like a mad man as the 2pm cutoff was coming at me fast.
Ya know the entire thing about fishing is, you really don't want them to bother you. Throwing a line out is a good reason to have an ice cold beer and relax....
I'll probably weld on a few accessories such as beer glass holder and fishing rod rest once the main structure is complete. I think that's better than cutting out pieces.
And I'll be more leaning down onto the end fence bit, rather than leaning against it. I'll do some more calculations but I'm sure the diagonal members will make this strong enough!
Some people should not be allowed near mathematical calculations.
Mendip I believe your first answer to be the correct one however I am not sure how you got there based on what numbers you have shown.
113 x 113 = 12769 but you have written 12796 so hence aging one's question, he was not questioning the final answer.
12769 + 12769 = 25538 which is the number you showed on you hand written sheet of paper. So I can only assume you wrote the number down incorrectly by switching the last 2 numbers.
But must have kept the right number/s in your calculator because 12796 + 12796 does not = 25538
So when using the correct square of the diagonal ala Pythagoras as equal to 25538 the square root is 159.806.
In the end as you have said it doesn't matter if you round it up to 160 just go full on Thai and bash it in there.
