Despite some negative reviews, I found this glass cutter to be exactly what I wanted and it really works.
The key is to READ THE DIRECTIONS.
1) It says to lubricate with kerosene; I didn''t have kerosene but I had some penetrating oil that smells like kerosene, so I used a squirt of it on the cutter.
2) I set up a straight edge to guide my cut - which was 44 inches long!
3) Holding the cutter perfectly perpendicular to the glass, I applied a couple of pounds pressure and pulled the cutter along the desired cut path, guided by the straight edge, exactly once. It is very important to only make one pass. It makes a kind of hissing noise as you pull it across. The scratch on the glass surface is barely visible, but it''s all you need.
4) Since my cut was very long, and taken from a large plate-glass window, I was working on a tarp on the garage floor. After making the scribe mark, I then positioned a piece of 3/4 inch PVC pipe exactly underneath the desired cut - so the glass was resting on the pipe and my 9" section was cantilevered out above the floor.
5) Again, since my cut was very long, I took another (larger) piece of PVC pipe and laid it lengthwise along the outer edge of the piece I wanted. (This could have been a straightedge.) Taking care to make the pressure on the glass uniform from end to end, I pressed down until the glass broke. It broke perfectly along the line that I had scribed on the very first try.
I went on to make other cuts, including much easier ones where I cut the 9" rectangle into 9" squares. Every cut was perfect except where I failed to follow the method (like deviating from the straightedge path and then trying to correct the problem with a second, parallel scratch).
I would definitely recommend this to a friend.
I''ve been cutting glass for window replacement and picture frames for 30 years or so so I know what I''m doing. This cutter works well for me and the idea of getting a fresh new edge without buying a whole new tool rocks. Yesterday I cut 12 panes (out of old glass, a total of 48 cuts) and the first cutter wheel is still sharp. At this rate, this tool will probably last years.
And that little instruction sheet - do read it. I''ve been snapping scored glass the old-fashioned way I guess, the instructions on that tiny sheet were worth the price of the tool to me.
I''d like to see a slightly more ergonomic handle maybe, with the cutter head angled as on a conventional cutter so it would be easier to apply a little downforce but other than that I''m calling it a winner.
I read all the reviews/tips/tricks, watched 10 youtube videos, oiled this thing, tried all ''blades'' on several types of clean glass, and then, had 4 people #who have used similar tools before for a living# try it out.... GUESS WHAT? It does not work. Those of you who said it worked, got lucky...I mean, if you mass produce 100s of tools a day, once in a while you''e bound to make one that''s worth the effort. This tool came with no instructions and any information I did find #internet, mostly# on this tool was irrelevent to using it. It''s not even worth the time spent to oil it.
I have very little experience cutting glass but this tool worked quite well for me. I have to think that those giving bad reviews simply are not doing it right, technique is everything.
The packaging I received did have brief instructions which include how to hold the tool and to use oil. If you haven''t cut glass before it would be helpful if you watched basic instructions on YouTube. And YES, you will have to practice before you can expect every cut to be perfect, just like any other tool which has a learning curve.
If I misplaced this tool I would buy the same one again.
This cutter works just fine. I have never cut glass before and my first piece came out great. It is simple to use and makes a clean cut. I don''t know why so many people on the reviews could not figure out this simple little tool. Dip the blade in a little oil, hold at a 90 degree angle from the glass and apply steady, firm pressure where you hear it score the glass, then simply snap and break.
I too, was not expecting a lot after having read the first several reviews. However, not having any other options in town, and with the low price, I thought I''d give it a try anyway. After a couple of dozen tries and not even scratching the surface of the glass, I was ready to toss it. But not before I read the rest of the reviews. After that, I was able to make the cuts I needed and it was really a piece of cake. Here''s what I learned that made the difference: the large wheel is a washer, not the cutting surface. I thought the little wheels were there to help it turn. Not so. They are what actually does the cutting. So understandably, you want that large wheel out of the way of the little cutting wheels. Make sure the flattened side of the large wheel is turned facing up, so that the small cutting wheels extend beyond it, free to make the cut. Secondly, the small wheels are not supposed to spin as you are cutting. They stay in place. One cutting wheel will do the cutting. When the cutting wheel gets dull, rotate the knob so that another wheel is in position. Thirdly, I dipped the end in WD-40, and then wiped it off. After watching a video on YouTube, I also learned that it''s important to hold the tool between your first and second fingers, so that you are holding it at a 90 degree angle to the surface of the glass. I also learned that you do not need to apply a huge amount of pressure on the glass. You WILL hear a sort of "ripping" or "tearing" sound as you are moving the cutting wheel across the surface, and that''s how you know it''s doing its job. Then you simply hold the two sides of the glass between your thumb and forefinger and bend slightly until it comes apart cleanly. It''s unfortunate that they don''t provide detailed instructions and tips with this tool. I believe the reviews would be mostly positive if they did. Good luck!
