Mill Scale removal

[DDA52]

are they the ones that look like a thick scotch bright pad only harder, if so i think you can get them at walmart also. it might only be the drill version at walmart though and thouse would most likly not work as well, but it might be werth looking if you are there, for the grinder type i mean.

Those are the ones, James. The grinder ones are a lot heavier from what I remember of the drill ones. I guess they would have to be, huh? Lot of difference in speeds.

Lot of difference in speeds.
i would think a lot of diferance in performance also, i can see it working well on a 4.5 grinder but would ??? it ability on a drill, especaly a small drill. nice to know they will get the job done on the 4.5 i'll have to look into getting 1, i have an up comming project that will require lots of paint removal, old thick (probly led) paint.

George,
I ended up ordering one of those myself based on David's recommendation. I will be interested to here your thoughts once you recieve it and then when you get to use it. Mine is supposed to be here on Monday.

It showed up on the bench in front of the door shortly after dark, the dog was in the window barking so they guy didn't even ring the bell. I got as far as opening the box (which had part of the top of the machine sticking out) to check it out. All I can say is watch the packing penuts, they went all over the shop. I did get them cleaned up and had a look, seems to be well made for the cost even comes with bolts for mounting in the floor. I will post some initial thoughts about it sometime this weekend after I get a better look at it.

George...got get you a Norton Bear-Tex Rapid Strip disc for your new grinder. It is like a mega conditioning disc. I used one the other day and it took all the mill scale off of a 2" flat in just a few seconds with very little effort. I get them at Airgas and a few other places. These guys are around 8 bucks each, but they are exactly what you are looking for.

I might have seen one of those hanging on the wall at Lowes, if I recall they were in the $12 range, thanks I will have a look this morning. If I remember right it kinda looked like a loose woven scotch bright pad with the strands coated with some abrasive. I remember thinking at the time it was a bit pricy, if it works then the price is fine.

George, the only ones I remember seeing at Lowes or Homey Desparate were the ones rated for drills. Could be wrong, though. I don't think I would try a drill one on a grinder. I do know Airgas has them most of the time.

Airgas here never heard of them, he did look them up and found they can get the 6-1/2" ones for 7 or 8" grinders which arn't rated high enough to use on my 4-1/2 or my 5". I called Graingers and they want me to submit my business linence and a credit app to sell me the size I want, forget that. I went to lowes and found them for 4 1/4-5" grinders made by GatorGrit and slso by 3M, the GatorGrit ones at $10 and the 3M ones are $13 and require a quick disconnect to use at $12. I got one of the GatorGrit ones and tried it on the Ridgid 4-1/2" and it works fine but I don't think its going to last very long. For some reason the Mill Scale on this peice is almost gummy, I know that sounds funny but thats what it seems like.

George, I'll look forward to hearing more as that is about all I'll be able to do this weekend. I am having the big "V" today at 3 o'clock so the weekend is pretty much shot. Even at that it will most likely sit in the box where the FedEx driver leaves it through next week (since it weigh 85lbs. )

This work FANTASTIC ALSO

Good call! An Ingersoll 182, CP9356, Patco P1-B or Cleco B1 would make quick work of that scale. For an inline, hand held tool that weighs five pounds, the power is incredible.

tHIS jUST SAYS jET CHISEL,,HAVE 2,,BUY NEEDLES FROM MC-MASTER CARR,,cHEPS,,,,AND DOEST EAT AS MUCH AIR AS YOU THINK,,,i THINK ITS ALMOST AS FAST AS SANDblasting,,,ame with the Company when i bought it so these have to be well over 30 years old,Jack

i don't really think a needle scaler is what you want for this job, although they do have their place in every welding shop! it will take a month to knock off all the scale on a table top and it will leave the surface looking somewhat like a golf ball (the divots won't be deep but they will be there) have you concidered a carbide scraper? i have one (intended for scraping excess glue off of wood glueups ) that i think would scrape scale off of a flat surface???? just a thought.

I work on lots of air tools, and recognize yours as an early model of the current Jet JSG-3328NS. They are a well made tool, fairly low consumption (around 8CFM).

Last week, a Jet JCO4-4R (15# chipping hammer) came in for a rebuild. What a fun tool 1800 blows per minute, each blow at 42 ft/lb. Even with the weight of the hammer plus all my weight, it was nearly impossible to keep the chisel on the test plate!

They retail for $489, but can usually be found for $350 to $375. Build quality is typical Japenese - very close tolerance, superb surface finish on internal parts (the ones that almost nobody sees ).

I see a fair amount of older ones, which tells me that they're hard to kill. You would not believe how some operators treat these tools ... sort of like a red headed stepchild

Had that done about 10 years ago, no big deal...it's mostly in your mind. of course the doc had this extreamly nice looking, young girl do the prep and assist and that didn't help things very much. Yep, you won't be doing any lifting for a few days anyway...good luck to you.

I do have a set of scrapers, I will have to give them a try...thanks, I wouldn't have thought of that.
