Re: [BlindHandyMan] Cutting Circles in Sheet Metal
Well I fill the drum about half way and then add a little dish soap that is to neutralize any thing in the drum. Then I put the plug back in and turn it on it's side and roll it around. OK now about cutting the hole today I made a little guide for my saber saw. Just a old paint stick it was just the right thickness well I drilled a hole on one end and then measured 3 inches and drilled another hole and mounted it to my saber saw by taking off the plate on the bottom of the saw it had only one screw and screwed the stick to the saw. Now I can drill a hole in the drum and put a bolt threw the stick into the drum and drill another hole to start the blade of the saber saw and cut and turn it around on the stick and hope I get a 6 inch hole out it. Now tomorrow I got to go the hardware store and get some metal cutting blades for my saw...

Re: [BlindHandyMan] Cutting Circles in Sheet Metal
Hi Dan No these were welded up in the boiler Makers Workshop when I did my Apprenticeship I spent 6 months there. We used to weld 4 together at a time that was a length which fitted into a coal skip for transportation underground. Cutting the ends out was quite inflammable at times because they had oil residue left inside. Welding up the ends needed sometimes to have a 7 pound hammer on hand for these drums were knocked about a fair bit. The four section drums were joined together underground by rubber tubing pulled over the gaps thus making a long tube from which dust was extracted from the work face. Very dusty noisy and dirty underground and at 750 feet down and miles of tunnels everywhere an interesting experience for a young guy then. If welding or cutting had to take place the area was tested for gas and the total area was covered with stone dust to prevent fires from happening. But I must say I really enjoyed my time there for my father grandfather and I worked there. Talk to you about it sometime.

Re: [BlindHandyMan] Cutting Circles in Sheet Metal
I am skeptical about scratching through an oil drum with a nail, perhaps it can be done but you want a load of patience. I doubt a router, that is pretty good steel. Again there may be cutters for steel but I have never seen one, that doesn't mean they aren't there of course. I also wonder about a standard hole saw, I did manage to more or less cut through a lid of a galvanized metal trash can a week or so ago with an old hole saw I didn't mind destroying and I did destroy it but it didn't like the job and that is only maybe 18 gauge. There are probably special metal cutting hole saws for that sort of job, I haven't seen any either in person or on the Web and I do quite a bit of Web snooping. I know that Ray has done some metal work in the past so maybe the sharp nail trick really would work.

RE: [BlindHandyMan] Cutting Circles in Sheet Metal
Hi Rob No I do not thing the nail would do the trick, do you know anyone with a Oxy cutting set. I have cut up plenty of drums and the steel is thick to withstand the oil being stored inside and the rough handling these drums are subjected to. For there is a scriber you clamp to the oxy set just put that in the centre and move the oxy cutter around to cut out the circle. If you are going to use an oxy set be careful there is no residue inside which is inflammable. We used to cut the bottom and tops of these drums up and weld them together to form a long vacuumed tube to suck the coal dust from the coal face when they were extracting coal. We had a vacuumed pump at one end and it worked great. If you could find a can or the bottom of a container slightly smaller than the required diameter and screw it onto the lid then you could use and angle grinder held against the can as a guide. Or mark out the circle centre punch it and split it into 4 using an angle grinder and cut around using tin snips feeling the centre punch marks as a guide once you have a quarter section removed then it becomes easier. Do you know a plumber close by who I am sure would have hole saws on hand that you could borrow.
