hey guys,

so over the last couple of days i have managed to get the gear linkage done (still can't quite get over that it has 5 gears!)

anddd the clutch was done today!

Tomorow will take some pictures for you and hopefully have the exhaust and alternator sorted :)

Then there is just a few more jobs to do to get her sorted!

Going to perhaps put a minor downer on this, but that welding is no-where near up to scratch for a chassis!!! There's major undercutting and the penetration is way to shallow!

You need more heat and to take it steadier. I'd get sacked if I welded like that at work, and thats on tool trolleys let alone a subframe to take more than about 20hp...

Seriously, a welding course at college may be a good idea. When you accelerate away those mounts will split. it doesn't matter how thick the plate is, you need at least 5mm plate for engine mounts and you'll need a 3 phase welder to do it properly, or at least a turbo 150 and you'd need to fillet the joints first.

Surely we must have some people doing motorsport tech or some engineers/welder fabricators (other than moi,) who can see this?

My friendly mot tester would fail that on every mount for it being insecure.

Jon.

Edit: forgot to add, by leaving as many holes and cracks as you have it wont last 5 minutes before the rust sets in either. you've got some serious water traps in there meaning it'll rot from the inside out and you wont realise until it collapses. And it may be the next owner who it collapses on.

hi, thanks for the comments,

i have actually addressed the welding since these pictures, adding more strength into the subby where needed (ths was actually prompted by a helpful personal message from a member on here)

i appreciate the advice though

Cheers

im likeing the transplant, seems a nice engine, i went for a honda b16a2 in a my own frame.

sadly ive got to agree with Crowson_punk the welding is just not up to scratch, nothing that cant be fixed tho

so basically throw the engine and subframe out the car, grind down some of the welds and try again with them?

sorta. take two steps back and look at your work through the eyes of ur MOT tester or engineer and imagine what you can do to make it better. why would he fail your car?

here is the link: http://www.sweethave...c...=3&modnum=3

there is alot of info out there to make you appreciate how important a strong weld is. by using the correct technique and equipment you will save time and ur job will look great too :(

I would try the mig welding forum lots of advice on there and plenty of pictures of how it all should look!

The welds should really look like this,
Posted Image,
or at least similar, (not the best picture but i don't have time to trawl the net now lmao.) Neat even and without undercutting. have a root through the guides on the mig forum, they really are very informative!!!

Kudos for trying and I'm glad your taking the criticism to heart rather than shrugging it off like so many people do!!!!

Jon.

Dont give up! Once you get the welding sorted out, your sub is gonna be much stronger. After that just take it one step at a time and you will get there.
The job isn't easy but it can be done. And rest assured, everyone on this forum wants you to enjoy your mini to the fullest (and are concerned for your safety).
But we are here for you every step of the way! So keep at it! You will get there! :thumbsup:
