Making front part again 2

The task has kept.
I made triangle and square iron plates and put on those frame and cramped.
I think that the square plate better is welded after welding BBS.
The preparing is important, I think. We japanese say that the preparing is 80%, the job is 20 %.  Welding Those incisions and triangle part.
Next, BBS is welded.
The Left sylindrical one is BBS. The direction of upper side is before right side. To adjust angle of 90 degrees, the spacers are needed.
The triangle part is weded on this side. and this is on the spacer and cramped.
Horizontal !
The left sylindical one is BBS. We see from upper side.
Welded. the job is rough. I need being calme down.
Then The edges of rectangulars are burned and bended.
Then, the thicker part is grinded.
Welded.
Really, rough...
And ugly. I noticed the sound of the electric runs when the welding started.

The other BBS is needed on this front part.
Cutting for the other BBS. I used a handy disc grinder. This side has the triangle plate.
Then it was welded with my rough technique. The BBS has a tube for the seat. However it isn't used for the seat, It is used for the front derailleur Shimano FD-TX51. IT's cheaper one. So, The angle of the tube and these rectangulars are adjusted at 66 degrees.
I noticed forgetting weldeing a iron square plate near the vertical BBS.
