The latter, it's only affected about 1mm^2 so far, you weld a bit on and by the time you got it down close to the profile you'll end up affecting a lot more of the lobe, and I don't know if it would beyond reason to weld it up and send it to swiftune to put it in the grinder and take it down to perfect?Why not weld a small blob of weld, then emery cloth it back? Or am i being silly?
Did I Destroy My Sw5?

Get a piece of fine emory cloth and make sure the edges are not sharp. Polish our the damage without abraiding the lobe surface.
The follower runs clear of the edges of the lobe so it won't be a problem.

Welding would be a very bad idea! it would affect the heat treatment of the lobe at the very least

OK, guys - I think you´re right! Swiftune couldn´t have said anything other than they did - they want to be sure AND they want to sell another cam.
I´ll stick with this cam - and if anything fails, so be it...
Thanks again...

Good man, the worst thats going to happen is that your going to destroy the follower - not a disaster
broken bits inside an engine? Nah no problem..
Worst thing that could happen is a camshaft that breaks, I saw one in my shor tlife ( only 17 years old) and it was a disaster..

I've seen the results of a cam follower wearing unevenly - it enlarged the bore and gradually canted over. Ended up paper thin and rattling round.
If it had been a normal block it would have been scrapped, but as it was a 1070S engine the cam followers were rebored to MGC size and saved.

How many times? Just linish the damaged area to remove any sharp edges, polish it back without touching the outer lobe surface and it'll be fine.
Start welding, filling with plastic putty or otherwise bu******g about with it and you might as well just scrap it.
It is NOT a problem.
