John Following the thread with interest. :bugeye: I have bought the Arc RT 130-030-00127, which is also sold as a motorised version. In that listing they state that needle roller thrust bearings are fitted. Is your table one of these or another type? Looking forward to the rest of the RT mods. Pete |

However I did buy my Schumatech DRO kit from Lester in the UK and it was a very easy transaction, and shipping was as fast as getting anything within the US. The Schumatech kit was configured just like Bogs photo's, components taped to the list so even an idiot like myself would have trouble mixing stuff up. Pretty much idiot-proof! I wouldnt hesitate to buy from Lester again, and probably will buy a Divisionmaster at some point. I have thought about fitting a stepper to my little table and running it off Mach 3 or even Turbocnc, but the self contained unit just seems like it would be much more painless. |

Spurry, Mine is actually a Vertex 6" jobbie, which has been cloned to death by everyone and his dog, so basically anything that I do to it should be able to be done to most RT's of that design, both larger and smaller. John S has already informed me that the 8" Vertex can be fitted with a thrust bearing of standard dimensions, but this 6" and I suppose smaller ones can't, due to the way the castings are made, a standard thrust washer fouls on the casting inside the unit. The dimension I showed in my last post is the ideal, but unfortunately, needle thrust bearings of that internal size come with an OD of 25mm, much too large to fit (don't worry, it isn't theory, I have actually tried it). John recommended to me that using an oilite washer should be almost as good as a thrust bearing, and that can be cut to any size so that it will fit. So I am following his superior knowledge on such things, and I am going to try it. I just hope my order doesn't get delayed by the Christmas post, otherwise I can't see any progress on this topic until January. With regards to the US lads wanting to make one of these types of units. I would suggest you root thru both Craynerds and Kwackers build posts for a bit of info. I am sure I followed up on something from there that gave me a link to a US site that made the boards and chips available for purchase in the US, so you could follow their lead and build one. Maybe one of those members has a lead. I'm sorry I can't be any further assistance on that one, I found the US site, but didn't think to save it, but it is definitely there. Bogs |
