My LMS metal gear upgrade failed to I took the step up to a belt drive.<br /><br />This kit is of barely acceptable quality, however, it is the best of the current offerings. I was appalled that for $250 using maybe $30 worth of materials that they didn't bother with deburring the parts and the finish of the pulleys it awful. But I can't use my mill as is so I installed it.<br /><br />I will say it functions well until you need torque. The motor pully is tiny and does not offer the belt much wrap so it slips. I retightened the belt repeatedly for the drilling of a 1.5-inch hole. This is why I preferred gears.<br /><br />It is what it is and when I get the time I'll make my own from the Hoss Machine plans.<br /><br /><a href="HTTP://WWW.OnCNC.com" target="_blank" rel="nofollow">HTTP://WWW.OnCNC.com</a><br />...<br /><a href="https://www.youtube.com/watch?v=wd0pbhHnyIo" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=wd0pbhHnyIo</a>
