Don't you just hate grinding welds Arrabil? I know I do.

You know, I don't mind so much. Gives you a chance to see the inside of the weld and make sure you did a good job.
On that bracket I ground flat the first weld, ground a 1/4" groove in the middle of it, welded it again but in a wider circle motion, and ground it again. Both times I got to see that I made a deep penetrating, and continuous weld which is very important right there.
So the positive reinforcement of success was well worth getting metal dust all over myself.
That and my welds are generally so ugly I just have to grind them where people can see them. Haven't yet figured out the secret to making pretty welds.

I get bored quickly because the grinding process isn't fast enough for me.
J-B Weld makes a good filler before painting or powder coating.
I've her regular MIG makes better looking welds than flux-core does; but I've never used flux-core.

JB Weld, now there is something I don't like.
More progress....
I built the other side of the subframe. First picture is me measuring up the two sides. I figure the two sides should be level with the drawbar bracket. Gotta love the iPhone. I also measured from three points on the rear housing. This needs to be level; I don't want a backhoe that sits crooked.
You can see the tacked support from a number of angles. I drilled the holes this evening but it was too dark for pictures. I'll get some tomorrow while I'm installing it.

On this side of the tractor there are hydraulic lines mounted to the holes I'm using. The mounting brackets luckily are the same width as the three washers I was already using to take up the slack of my bolts. On this side I welded the three washers to the inside to equal out the mountings. First I welded the washers together, then to the support.
And some more pictures of this side of the subframe.

Some updates....
Here you can see my reinforcement of the support joint and the two holes I drilled.
One of these holes will need to be redrilled lower. The one bolt doesn't go on because it obstructed by the tractor rear case. I'll fix that when I go to paint.
And some pictures of the clearance under the tractor. Everything is above factory low points.
