what do you guys use in tight spaces for grinding?

I am welding up the seams in my engine bay (not the best welder in the world and I'm using flux core wire so there is a bit of splatter) and their are some areas that i can't get my big angle grinder down in to. I have tried a few different things with varying results and have come to the conclusion that there has to be a better way. I'm hoping there is an attachment for a 1/4" die grinder that would work but i haven't found it. Any advice is much appreciated, if you could let me know what you use and where i can get it that would be great.

Also i would like to say that I am doing this to stiffen up the chassis not for looks.

id use a carbide bit to roughly get it down then go from there with some type of heavy grit sanding. id advise you though that seam welding has been prone to cracking, especially if you plan on tracking the car, and grinding down the welds will probably make the weld even weaker.

 

this ^^^^

 

how about stitch welding? does it have cracking issues?

 

how about a dremal tool

 

A dremel isnt powerful enough for that. which is why a die grinder and carbide bit was recommended.

 

yea i tried a dremel and it just bogged down.

 

thats what i used on my bay yes it boggs and takes a while but it was the only thing that would fit

my bay

 

its not really the type of weld your doing on the seam, the issue is when driving the vehicle it flexs at the seams which is what causes the cracking. i myself cant justify seam welding but many people can. ive seen 4-5 seam weldded cars and within a year they all had at least 1 cracking issue. for a race car no big deal just clean it up and reweld, but if you plan on keeping it pretty its more of a hassle

 

A die grinder is the same size as a dremel...........

 

Die grinder is probably your best bet, get som 1" 3m roloc sanding discs and arbor. they work pretty good and get it tight spots.

Something else I have is a dynafile, mini belt sander, works great!


The model I have is about $500 but there are some no name, harbor freight knockoffs that I am sure you can get for cheap.

 

i have a 1" 3m roloc sanding dics and arbor but the sanding pads just got chewed up really fast. what disc attachement do you suggest?
