I have several 5 gal. plastic buckets with a tight fitting plastic lids that I want to remove. The lids are not the typical vertical slots that you just break open to pry the lid off so I need another approach. I tried cutting my own slots but that is extremely labor intensive and messy (I have 20 buckets to do.) It appears my choices with a router are a slot cutting bit or a straight cutting bit. Does anyone have a suggestion about how to do this, possibly with a jig? The lids have a rubber O-ring just under the outside rim so I would need to cut below that and above the plastic hook that secures the lid to the bucket.The attached diagram is a cutaway of a lid top section.
Trey, attach a guide bushing to your router and it will give you the needed offset to use a slot cutter. If your reason for cutting the lids is because they are difficult to open a 5 gallon pail opener only costs a couple dollars.
You are making a easy job to hard I don't think the maker of the buckets wanted to make a string with one end, so to speak what goes in must come out and I'm sure they have a tool/device make just for that job on that type of bucket..I would suggest you call the guy you got them from and ask how do you open this thing...
Bob, I agree with you, I always try to look for the easy solution first. In this case the guy I got the buckets from had no idea how to get the lids off. It turns out he never takes them off, just pours the contents out of the spout in the lid. In researching the bucket website it didn't list a tool for lid removal so I sent them an inquiry about it.
Thanks helped with my problem I had a 5 gallon pale trying to figure out how to get the lid off. Went to my home center sure enough in paint section they had the tool for removing the lid just a couple bucks..
I am giving some tought to your problem and perhaps the better tool to remove the lid consistently from the buckets, may be the table saw, say you add a tal supprot fence and some supports to each side, then just rotate the bucket carefully on the spinning blade, which you can vary how close to the lip or how centered on the o-ring you want and by rising the blade you can control the how fast the lid is cut away, you can get carried away and even build a cradle with some old inline skate wheels that help you compensate for the taper on the bottom vs the top part and make it glide smootly as you turn it. Same concept as your original tought but you bring the part to the machine rahter than the machine to the part.
Ziggy, my table saw is in storage and not accessible at the moment. I had thought about doing what you said but couldn't figure out how to work around the wire handle that sticks out of two sides of the bucket. That messes up the bucket rotation so I went with the router instead.
I used a grinder on the first two buckets and ran in to two problems. 1} It was really hard to guide the grinder consistently and 2) It made a real mess. I had plastic "skittles" all over the place.
Here at the campground we have chlorine tablets for the pool that come in buckets that are a pain to open.
My method at first was to use a utility knife to cut vertical slots about ever 3" in the lid. I finally got smart and started using a Dremel tool with a saw blade. I cut all the way up to the O-ring, but not through it.
Make sure you slow the Dremel down or the plastic will melt around the teeth of the blade, also let it cool for a second or two between every cut.
Did you consider a root zip or Sawzall?
Either could be attached to a sufficiently long bar which would ride the top of the bucket. I'd start with a 2x4 screwed to a strip of plywood 2' long.
Step on the fence and rotate the cutter around the bucket.
Distance of cut governed by thickness of fence.
The plastic is probably only about a 16th thick, why not just set your depth and freehand right around the top, just over the where the sides of the bucket are. Doing that, the center of the lid will come right out. The sides will still be there with the oring, but thenyou can just make a single cut through that and peel that baby right off.
I think your idea will work well on some of the next buckets that I have to cut. It wouldn't work on the first ones I did because I wanted to have the lids available to use again on the buckets. They work fine, they just don't lock on anymore.
I need to cut the lids off in such a manner that I have just trimmed about 1/2" off the bottom lip of the lid. That leaves the lid intact to reuse on the bucket, it just doesn't "snap on" any longer and is easily removed.
An old adage of mine is "If its too hard I am doing something wrong" Which makes me want to know why that lid was designed with such difficulty. Is it a design flaw?
BTW that adage has prevented many mistakes by yours truly
Builder's saw, with the rip guide should work. That's what I use to split 40 gal. carboys into two pieces (minus the rip guide). Works like a hot damn.
Your buckets are polyethylene, not hard plastic?! If they are hard plastic this could get a bit dangerous if they shatter.
Won't the buckets handle interfere with any machine operation?
On the bottom of the bucket, moulded into the plastic, will be the manufacturers name and hopefully contact info.

Have you tried a heat gun and the pail tool? I think I know what you're dealing with, I open all kinds of plastic pails for paint, sealants, and adhesives and there is a small percentage of Mfg.'s that really seal the top to the bucket. I'm usually able to overcome this using a utility knife but it is in a situation where I only am dealing with a bucket or two at one time.
Good luck with the pails from Hades!
