A little process today. I am not sure that the spot-welded, cone-shaped support will be strong enough. 

 

 Naturally there will be more spots when finished. I just don't want to drill 10 spots if I f@ck up 

 

What's your opinion ?

Excellent work,the cones will be plenty strong enough,the shape gives the strength.Steve..

Spots look good.

Do a test piece on a couple of scrap pieces and then try to force them apart with a hammer and cold chisel. It should be difficult to part them.If you hammer hard and long enough they will come apart but so long as the centre weld stays intact on one piece you're OK.

As above, but if you take the two welded test pieces and hold one-piece in the vice you can use a pair of pliers to pull it apart. If you have a hole on one of them, you're golden. ?  _20200223_180329.JPG   32.85K   1 downloads
You should have a 4mm pip after ripping to have a strong weld.

I was so immersed in the work that I just welded and welded   I hope it will be strong enough, but tomorrow I do the test in the vice.

Hello, please help me a little bit

 

Is this the correct orientation of the rear mount ? I mean the thick part is at the back and the thin is forward.

 

The hole of the bushes is NOT on the middle.

Thanks

I belive those are the wrong way round.
Someone will confirm in a minute...

On my old mini they are this way too, just had a look, but it might be wrong as I built it 20years ago with no clue. ?  image.gif   43.18K   3 downloads

Although the spot welds look good i would seam weld there as well. Lots of forces transmitted there so seam welding will ensure you have maximum strength.

I think that I'll seam weld only that cone. Unfortunately the aligment of the cone support bowl on which the rubber cone seats is not so good.

 

I also thought that I cut the cones from the old pieces and weld them to the new beams, but there is too much rust. So I reject this idea.

Cones are almost finished. Some griding is needed.

Cone welding and grinding is finished now on all 4 beams.

I had more ideas about the rim of the support and finally I made this piece :

It fits like this. The arched flange will be seam welded to the cone.

The heel fits to the other side and it will be spot welded
