Review on 🔧 Cabinet Hardware Jig - Durable Metal Drilling Template with 5mm & 4.2mm Holes for Knob/Handle/Pull Installation. Includes 2 Drill Bits, Fittings Set, and Inch/Metric(2 Scale) Measurement by Gary Morris

This product is made of high quality material, it's just poorly calibrated and can't be used right out of the box without checking it carefully. On the plus side, the parts kit is metal and mostly well-made aluminum profiles. On the other hand, its accuracy cannot be relied upon from the start. First, use a square to check that the two rulers that form the capital "T" are perpendicular to each other when assembled. If it doesn't, you're wasting your time. time of using this kit. Mine was perfectly square within 2,000 inches by 6 inches, it was square. But when I installed the big slide stop it was 1/10" out of 6" which was a big mistake and all the handles were crooked. The problem was that the large stop consists of two parts bolted together, a flat plate and a slide profile that presses against the vertical black ruler. I had to install a .018 feeler gauge under one side of the profile to keep the plate exactly parallel and perpendicular to the horizontal silver ruler. There are a number of fixes to address this issue. 1 you can add a .018 shim under that end of the profile to make it square, you can file a chamfer very cleanly and accurately to narrow the profile by .018 on one end, you can place the part on the router and just edit it. Finally, the manufacturer can add two small set screws opposite the knurled stop screw so you can align and position them exactly parallel to the x-axis silver steel ruler, very carefully filed to the required thin pitch. Tested each time with installation on the current T frame. After a series of tests, I got a deviation within 0.002 x 6 inches. A big improvement over the 0.101k error we started with. The first two images show a break with an error of 0.101, then a pen error correction with an error of 0.018 to fix the error. The two countersunk screws had to be countersunk further as they protruded 0.008mm and affected the accuracy of the sensor even when they hit the edge of the case. I've found the pull approach to be the easiest way to make corrections to a factory part, even when I have a busy machine shop. I put some blue Loctite on some of the threads to keep them from loosening and losing the gauge gauge. The end result is a very strong and very precise device. One final note: be careful not to throw away the small set screws and Alan's wrench stuffed into the bottom of the small brown padded envelope that contains the two drills. I found my 4mm bit to be very poorly sharpened but the 5mm bit was fine. I also bought a set of GoldenWarm plastic hardware templates and it came with a very good quality 5mm wood drill bit with a very fine brad point which ensures your drill bit doesn't go off center. The $8 set is for the drill only. I hope this helps others before they rely on this contraption and end up with crooked handles and pierced cabinets that are difficult to repair. Sincerely, BSP
