The Boston Gear ND12B Spur Gear has received mixed reviews from customers. While some customers praised the high quality and timely delivery of the product, others expressed disappointment with the lack of a keyway and set screws, which were pictured in the product listing. One customer highlighted the nice quality of the gear but mentioned that it did not come with a screw or keyway as advertised. They felt that the advertising was dishonest. Another customer had a positive experience using the gear to repair an old Southbend lathe. They mentioned that the material was easily machined to fit their specific requirements and appreciated the inclusion of a spec sheet. However, another customer had a similar complaint about the missing keyway, but still gave the product a higher rating because they planned to try welding it to the shaft for their go-kart project. One customer mentioned that the gear worked well in their DIY project but had to add a set screw to drive the ring gear instead of clamping it on the shaft. Overall, while the Boston Gear ND12B Spur Gear is praised for its quality and versatility, the disappointment over missing set screws and keyways is a Consistent issue raised by customers.
