A bit of work with the linisher and a flap disc and its looking much better
I trimmed a lot of the excess material from the mount and smoothed it out a bit.
Should all look nice when it's polished up.
I think I found the issue with my TIG. The argon bottle was almost empty and I just wasn't getting enough flow. I think the electrode wasn't good either. A new bottle of argon and a freshly ground electrode and its working nice again.
Cheers
