There we go! laugh

More progress on the front uprights today, and I have the main body of them done. It's late again laugh so I'll just add pictures and a few words.

These little top caps are very fiddly!



Made a little jig for it - reversible for the other side, too.





I had to make another forming tool for these upper parts, as they have a tighter radius than the lower legs.



And then a flash of welding later.. I have a massive erection. laugh











And finally some slutty weld close-ups. biggrin







So pleased with how they're coming out! I'm going to have a slow day tomorrow as I ache all over, so the next update will be at the weekend when hopefully these are finished. smile

I'm not worthy of posting here but I am. This is the best build on PH and usually I would have lost interest. Every page every post is fantastic. I really do look forward to the end but will be a bit unhappy at the same time.
Like watching your a great movie.

Agree with above! More like artwork than metalwork.
Out of interest, what do you do for a job? Is this a hobby or a job as well?

Thanks guys, glad people are enjoying the build!

I have a desk job as an engineer, but was very lucky to get my placement year with some highly skilled fabricators at BTB Exhausts, so I learnt a lot from there. It's a hobby at the moment, but I don't want to work behind a desk for the rest of my life so I figure the best way to get out of that is to get stuck in to this! smile

Quick question, have you done and hand calc's or FEA on the spindles in the uprights?

I ask because they look very light.

How the hell do you fit all this progress in around a desk job as an engineer? All I have managed in the last month is to wack a new slave cyl on my mini! Mind you having a woman in your life is a hobby ruiner smash

Very large diameter probably allows for this?

Yep, with a nice documented build log (in a folder [for the old school]) and the web its a class CV that is for sure.

Yeah I've done FEA on all of the suspension components. The diameter is quite large and the wall thickness is greater than it looks at the point where stress is the highest; the car is also only 600kg. smile

Simple solution: no woman. laugh

I've taken this week off work, so it isn't always like this mid-week! Also helps that there is fk all else to do around here. laugh

Lack of weight always helps. I did wonder if they looked thinner than they were in reality.

Is it just me who thinks it'll be a shame to hide all this fabrication work under the bodyshell!

Outstanding skills and progress.

Just seen this and can't believe that I've missed it until now - what a great read!

Thanks for the kind words, chaps. smile

Yesterday, predictably, I was hungover. laugh So today I tried to make up for lost time by getting on with the brake calliper mounts, and as such there is a lack of in-progress photos! Anywho.. I made a jig, then fiddled about profiling some sheet metal, then welded it all up. Behold!









I tried the caliper on..





Then fitted the disc to a spare hub and checked everything fit ok. (I actually did this while it was all tacked up, but this makes a better picture!)









Now, true to routine, it's time for a very late dinner. laugh

That looks st!




getmecoat
























Who am I kidding? It looks fantastic. As deltashed said earlier, I too am not worthy of posting here. I've worked in engineering for 28 years, but in commercial/admin after my apprenticeship. Threads like yours really make me wish I'd carried on with the practical side, so that I may be able to construct something to half the standard you're doing. Due to this absence of skill, I have to content myself with watching threads like yours.

Just keep thinking of people like me, and keep the updates frequent & detailed please. coffee

Haha thanks, I'll be sure to keep the updates as in-depth as I can! smile

Aaaaaaaaaaand finished! (Or as good as..) The steering arms were quite tricky, but they look great now that they're on.







Megaflow - no weights just yet, but I will do so once they're powder coated!

So, sadly I'm back to work tomorrow.. which is a shame as I'm so close to getting the wheels on! Hopefully that will be a nice job for next weekend. smile

OK I am going to ask a silly question. While the welding looks very well done and I am sure all the surfaces are prepped properly is there any need for weld inspection? Be it surface flaws or volumetric cracks/flaws. I have no experience of how mass prodcution parts are sampled and NDE/DE tested never mind how a one off project fairs though. You may be confident that the welds are not porous, material is flaw free and there is additional redundancy/FOS in your stress utilisations. To be honest there is a chunkiness to the build which tells me it will take a beating.

Being from an oil and gas background I am concious the weld inspection and testing I see is largely pushed by the fact there are pressurised volumes of hazardous fluids or gases and the insurance companies need to see bits of paper to be happy.

OK silly question over.
