I got both engine mounts tacked in place, but you cant really see them, so I'll post pics when I yank the donk to fully weld them.
I have been busy building the gearbox mount, first up I had to build something for it to bolt to.
The SHS is 40mm. Its worked out perfectly and I would recommend it to anyone.
I'll let the pics do the talking, feel free to bug me with questions.
These go here, one each side of the tunnel.
There was PLENTY of trial fitting and trimming getting in and out under the car to get these right.
I wanted some meat to drill and tap the mount into, so I cut some strips of 6mm plate with the 5 inch to weld inside the SHS.
They are about 6 inches long.
I needed to plug weld them inside, so some holes were needed.
I filed the burr off the inside so I could clamp them down nice and flat.
Plugged.
And sanded smooth.
I used a 5 inch sanding disc cos I prefer them to flappers. Cheaper and a better finish for stuff like this.
I tacked the two halves together, but forgot to take a pic.
I also needed to make the beginnings of the cross member
I started by chopping up another piece of RHS I had laying around because I had no angle iron.
After offering everything up under the car, I calculated (guessed by eye) the position of the angles (which theoretically should run on the centreline of the trans mount),
clamped them to the side mounts, then matchdrilled and tapped them.
This is why the plate was welded inside the SHS.
Then I jacked everything up tight against the floor, stitch welded it all in and knocked off the rough edges with, in this case,a flapper.
I wirewheeled the floor first to make welding easier. (Well, as easy as it can get laying cramped on your back welding upside down)
Then I bolted the angles back on. They needed a little trim to clear the welds.
Then I did some measuring of the position of the side mounts in relation to the transmount so I could get some angles worked out with a mud map.
Did some measuring, marking and cutting
Then welded and sanded it up.
The top notches were done last after welding and sanding.
After offering it up again I discovered I hadn't quite got the angle on the side mounts in the right spot, (I missed the centreline by THAAAT much..) so I had to tweak
the crossmember and kick the sides back a scratch.
I did this by just running the cutting wheel through three faces (top,front and bottom) of the crossmember, clamping it together to close the gap,and welding it back up.
^^^^that's the gap^^^^...I forgot the pic of it welded with that gap clamped shut.
I also wanted a bit of meat on the top of the crossmember so it would stay put, so I welded a bit of 6mm flatbar to it.
That was it for today...you can probably see where its gunna finish, but I had some other stuff to do so packed it in for the night.
