Grinding suggestions.......

admin

I am building an "Asian" inspired piece of furniture and decided to build a quick and dirty practice piece to help me identify any problems that I may run into during the actual project. I am VERY new to metal working and my plan worked perfectly........I have identified a problem. I need to know what is the best type of grinding tool I can purchase to reshape my "inside corner welds" to a smooth finish. I can handle the outside corners and flat surfaces......but I have nothing small enough to fit inside the pieces I'll be building. I have included a photo so you can see my practice piece.

Reply:a die grinder with a carbide bit?  or a dremel tool ,  rat tail file,  sand cloth on a dowl daye
Reply:I tried the dremmel tool..........it was pretty slow and it heated up pretty quickly. I'll have about 40 inside welds to clean up. I'll look into the other options......Thanks!!!!!!!Timmer
Reply:I think you could fit a 4 1/2" grinder in there with a cutting disc on it. The thinness of the cutting disc makes it work well for inside corners.Also you can get sanders that are built on a grinder body that have an extended arm about 10" long with the roller and platen on it. The belts are only about 3/4" wide. That's what I use and I build a lot of furniture.

Reply:If this artwork is painted eye-candy, don't weld the inside corners...JB-Weld or Bondo and square file.  Just a thought....
Reply:By clean up what do you mean?Are we talking "looks like it was made from a single chunk of material" or just smoothing it out a bit?
Reply:Air file.
Reply:The piece will be powder coated. I tried to talk everyone involved in letting me get buy with painting the steel.....but no go.  The inside corners need to be really square to get the desired effect. I tried using the cutting disk idea and it is working very well. Its a bit touchy, but I have it figured out so its safe and very accurate (I don't remove too much metal).Thanks for all your suggestions. I'll post a couple of progress photos when I get things laid out.Timmer
Reply:Don't weld them. As long as there is no gap in the steel and the powder coater is aware that you don't want the crack to show it should be okay.
