Spot weld cutter

-
My concern is longevity of the belts. Never used one. Been wanting one for a while.
Use the 80 grit and they last a while. Go to 60 or 40 and they're toast pretty quick.
 
Next time I'm in town im gonna run in harbor freight and get one of those belt sanders. For 30 bucks it would have a ton of uses. That would be a handy little tool for hard to reach places.

The Blair definitely work better than the HF type but the HF will work if you are methodical. But no matter what you use, slow speed and consistent pressure is key to getting good results. If it starts walking around you risk chipping teeth even on the Blair. Oil helps. Pilot hole or "dimple" is key for cheap ones. I found my Blair will usually work with a good sharp center punch mark. If it starts to walk I partially drill a pilot. I have one of the stepped drill bit type but really haven't tried it yet, but there are multiple opportunities upcoming.
Thanks for the tips!
 
A lot of the cars I drilled out were ones that were not worth saving and a lot of them I did pull out of the crushing yard.
Years ago I did cut a few E bodies and a couple B bodies that now I probably wouldn't.
I tried a belt sander and it just didn't work for what I was doing. If I was removing a junk pan to install a new then it would be fine.
 
Dartfreak75 heres something else for your arsenal. A china freight bucket blaster. It does make one hell of a mess, and sand gets everywhere, but it works great. What helps a lot is big tarps to catch the sand, and to cover up areas you dont want it to get into. It needs to maintain about 100psi minimum to clean, but it works great. I payed $40 for it, $20 for a blast hood, and your going to want to wear a respirator to not breathe the dust. I have used it several times this past year on big stuff I cant get into a sand blast cabinet at work. This thing works great.

FYI:

HF shows one tool under "belt sander" but shows two more under "belt grinder", including a more expensive one with a longer reach.
 
I think the ones under belt grinder are air powered.
 
Those suck. Get a mini belt sander and some 80 grit belts.
That will work OK. However, I like to use this type of a spot weld cutter. The spring loaded tip in the middle can slip and wander, so I just drill a partial hole (I try to only go through the top metal layer) with a 1/8" bit; then that tip will not wander. I get these at Harbor Freight for about $5. Notice that the cutting bit has 2 sides. I have had VERY good luck with these. They actually last a long time. Believe me or not; your choice, but I am telling you that I have had the same luck/success with these as with the much more expensive ones I have tried.

I ended up just using a 1/2 inch drill bit and an angle grinder for the hard to reach places. Worked good I got one side off just gotta get the cab corner out and everything welded back in. The passenger side is alot worse.

I'm thinkin "cab corner?" "That Dart ain't no truck", then I see the last picture. lol
 
I uses the HF one too and it easily lasted through 2 inner fenders. I flipped the cutter half way into the 2nd side with no change in performance. I center drilled 10 at a time and then used the cutter as the pin skates as noted. Nice clean holes, took about 8-10 seconds a hole at a slower speed IIRC. Nice thing I found is the panel can be put back on and the holes line up to the bump of the old weld, like a giant lego piece. Makes alignment easy if your putting it back on. For busting apart, the heavier tools would probably make more sense.
 
Yea I got about 3 or 4 projects going at once lol
I always find it pretty hilarious how you come on here all meek and mild and **** askin for help and then just dive in and show us all how to do it.

This isn't my first rodeo at doing patch panels I've just always done it the hard way. I was wanting to buy the right tool for the job to make my life a little easier lol iv always just used an angle grinder and cut thru the spot welds. I will admit the drill was alot cleaner but was hard work lol hopefully someday I'll be able to invest in one of those blairs.

The key is whatever works for "YOU", not somebody else. We all do things differently.
 
Here is a 98 chevy I did last year for a buddy of mine. I did cab corners and rockers turned out good. I just gotta learn how to blend paint a little better. The new black was alot shinner that the original black
