Re: New 7x12 delivered and on the bench.
¿ªÔÆÌåÓýI don¡¯t think there is any advantage to metal over plastic for all the main gears.? You could instead put that money to something more useful. ? A chip guarding cover over the apron gear is probably a very good first addition to the lathe.? I think most make this themselves from thin plastic.? But you can buy one ready-cut from this eBay seller (and I have no association with this).? The photo there shows you what it looks like and I¡¯m pretty sure it is described elsewhere online. ? ? A milling attachment for one of these only suitable for light milling.? VERY light milling. ? Don¡¯t know if you have any lathe experience.? But for these small lathes I recommend HSS (High Speed Steel) tool bits, carbide inserts nor carbide tipped.? Also, it seems the cheap ¡°carbide tipped¡± bits tend to be exceedingly low quality.? Although, using something like inserts will work, you will likely get better results with HSS.? And if you don¡¯t know already, learning how to properly grind the angles on a tool bit (meaning you need a grinder, preferably with at least 6 inch wheels or an even fancier tool sharpening machine if you want) is sort of a first step. ? Regarding the lathe itself, the things to check are, well, everything.? People report all manner of misalignments, crud where there shouldn¡¯t be crud, sloppy gib fit, you name it.? Some have called it a ¡°kit¡± based on how much work they have put into it to improve it.? But for some, it has been fine out of the box.? It probably has a lot to do with what somebody is trying to do with it.? And what they view as ¡°good enough¡±.? Some give the impression that all they do is improve the lathe and make accessories for the lathe and perhaps never make a part for anything else.? That¡¯s OK to make lathe itself a hobby, but it just seems curious to me. ? You will probably find that the lowest power feed rate isn¡¯t extremely low often leading to a ¡°grooved¡± looking finish (depending on tool bit geometry too, of course).? So you might want to consider looking into modifications to make it slower.? Some have done this with a mechanical reduction.? Some have done it by separately motorizing the lead screw.? There is no end to how to modify these things. ? Chuck K. ? Sent from for Windows ? From: MZ Rider
