- Hi, I'm the one who bought the Milwaukee saw above. I agree that
- it may not have been intended for metal working, by sometimes I
- have projects for which nothing was designed. For example, I need
- a very big pot for a big (18 feet tall, 10x15' wide canopy) tree
- in our 2 1/2 story solarium. The local scrap dealer had a 38"
- diameter double walled stainless kettle. In testing for leaks, the
- previous owner had over pressurized the thing and blown the inside
- liner inside outish. I got the 250 monster at 30 cents per pound,
- took it home, and ran a cut around the outside layer just below the
- rim to seperate the two pieces. (The scrap yard took back the 130
- pound inner peice at full credit, as we had agreed.) I got a nice
- stainless pot for the tree at under $50 including the cost of the
- saw blades.
-
- I used my circular saw to make the cut, and a belt sander to
- smooth it (and a cutting torch to cut the other, few connections
- between the two layers.) What tools would you have used?

- dust mask, etc, etc, and work on such projects outdoors on the
- driveway so that there is plenty of ventilation.)
