2 questions re: groinding

[rtd]

1) What do you use to grind a flat surface? A typical 4 1/2" grinder with the tapered laminated 'sandpaper' disk comes to mind and it might be better than a standard wheel but it's not really for flat surfaces. I've thought that a belt sander might be a possible choice. What have you used with success?

2) Sometimes the appearance of the finished weld and adjacent surfaces is important, and a typical grinder can't get to all the surfaces that need to be cleaned-up. What do you use for this detail grinding work? I've thought of a Dremel or something like it but I don't know if these small tools can take the side pressure. How have you solved this problem?

Thank you

Really depends on exactly what I want to do, then I pick one of these to work with.

Once you sharpen your welding skills, little grinding needs to be done. I dont grind my welds. The paper discs you describe are really for blending the weld into the work. if you have a lot of overweld or burn in, it's difficult to blend the welds into the work. that's the beauty of Tig welding. There is also a needle scaler that hammers your welds and it will leave a hammered look. Other than that it's Cut offs, blenders, Wire wheels, grinding wheels and discs, carbide burrs, cup stones and scotchbrite pands, There are few other options. I would say look at fine grit cup stones for flat surfaces.they go on your grinder and do a good job on flat surfaces.. Another possible one is an encapsulated wire cup brush but it wont remove material like a cup stone. Good luck..

When I have a special nook or corner, I use some sort of Tungsten deburring tool on an air powered die grinder.


I know it's likely a typo, but for a moment I thought the title might be a Freudian slip? Got a little tight in there with the grinder and slipped maybe? :shocked:

Thanks for the replies.

Yes it's a typo in the subject line, and yomax4, my welding skills do need improvement.

I'm looking into die grinders; any specific recommendations for use or those to stay away from? I'm generally inclined toward Makita or Bosch.

I was playing football and got a real bad groinding one time. Hurt for hours!

I'd really go with an air powered one. ANY air powered one is as good as the more expensive electric ones in my experience. I have a higher end Campbell Hausefeld. IF you bog it down, it won't smoke the brushes.
