This is a very informative post for those wanting to try the same thing. From my point of view the steppers where too small in the first place so I was surprised when you said it was working good. Really the next step for people is to reduce the friction and the racking of the carriage might be less of an issue. Did you modify your bushings at all?
I'm really surprised that I have not seen some one use 1/4" flat CRS and roller bearings as an inexpensive linear rail system. If you don't know what I'm talking about take a look at this site. http://www.cncrouterparts.com/ It's an affordable starting point that would be better than the stock bushings. It's not cheap when you add up all the steel and components, but much less than true linear bearings and precision shafts. I was probably the person to mention the pin and shaft collar. I've never seen one for sale in the USA. It would be very easy to make one. I saw the idea here http://www.lignolathe.com/en/face_plate_system/index.htm. Since our chucks need a shaft collar to seat squarely on the spindle it seems like a good idea. If this is beyond your skill level and tooling, contact me offlist and I'll make you one. -Tim ----- Original Message ----- From: Chainlink To: legacy-ornamental-mills@googlegroups.com Sent: Saturday, August 04, 2012 1:52 PM Subject: Re: Legacy Parts The biggest problem I have to deal with is the rack on the carriage when changing X directions. I'm actually happy with the lead nut on the X and Y and don't see a problem with it. The second biggest problem is that I need to have some kind of set screw on my self centering chuck. It spins fine in the one direction but it loosens when it spins the other direction. There was some chat on here previously about a stop collar with a pin in it, but I haven't been able to find one and implement it yet. -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
