Begat, I have an earlier version of the OM that was nearly eight feet long. Someday I'll cut it down in length. Anyway, you'll find that the rails will sag quite a bit making it impossible to mill an even cylinder. I fixed this by creating a simple frame to apply upward pressure along the rails. It is adjustable along each side and length. I posted pictures and a description in the forum a long time ago.
Good luck, Grant -----Original Message----- From: legacy-ornamental-mills@googlegroups.com [mailto:legacy-ornamental-mills@googlegroups.com] On Behalf Of begatbrown Sent: Monday, December 05, 2011 4:25 AM To: Legacy Ornamental Mills Subject: Re: Extruded rail material source Hello All, Other than needing to acquire a longer lead screw, what is there preventing someone from using two 900s to make a 8 foot system? I believe the carriage would still be able to ride through from one frame to the other. Clearly one would have to place both systems on a common platform and perhaps connect them to make sure the two stable. I have few mechanical skills, but to me seems away around looker for longer extrusions. I also think the cost of the alum rails are roughly $25 a foot thru legacy. If that's true four 9ft rails would cost approx $900. That's a lot if you don't mean use the system to make money, but not much of an investment if you mean to make columns for the market. Moreover, since Legacy decided to withdraw from both the small and the large ornamental mill market, they have left the door open for innovation.

I do believe that when you download the modutek catalogue is shows the bolt head also sliding in the slot. I have been moving 8 or so 10 foot pieces of the one slot stuff for years and plan on making the panel saw from some plans I have and also looking into longer acme screw material for a longer machine that is about 2 feet longer than the 900 I use now. I have been looking into making a rail extension that will just bolt up. I am looking at moving the carriage onto rollers and making an arm tht bolts to the lead screw bracket that would continue the drive for a longer distance down the rail. Nothing further in planning than the drawing board at this time. > > As a note I am working on a few custom candle holders that are about 4 feet high with a hollow spiral in them made from some 4" stock I came into.

If one is looking for extruded aluminum to make rails go tohttp://www.tekno.com/html/downloads_.html. I used to work at a conveyor company and we used very similiar extrusion. As far as the nuts and bolts you can get those a lot cheaper from a local supplier like Fastenal. the plans from one of the mags for a panel saw used this stuff. > > Carl Stigers > > > yes it does look like a little bit of legacy rail in there I wonder if he > > got it from legacy if not id love to know were wouldn't it be great to be > > able to buy rail for our mills elsewhere > > No virus found in this message. > Checked by AVG -www.avg.com > Version: 2012.0.1873 / Virus Database: 2102/4656 - Release Date: 12/04/11 > > -- > You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group. > To post to this group, send email to legacy-ornamental-mills@googlegroups.com. > To unsubscribe from this group, send email to legacy-ornamental-mills+unsubscr...@googlegroups.com. > For more options, visit this group athttp://groups.google.com/group/legacy-ornamental-mills?hl=en. > > -- > You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group. > To post to this group, send email to legacy-ornamental-mills@googlegroups.com. > To unsubscribe from this group, send email to legacy-ornamental-mills+unsubscr...@googlegroups.com. > For more options, visit this group athttp://groups.google.com/group/legacy-ornamental-mills?hl=en. > > -- > You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group. > To post to this group, send email to legacy-ornamental-mills@googlegroups.com. > To unsubscribe from this group, send email to legacy-ornamental-mills+unsubscr...@googlegroups.com. > For more options, visit this group athttp://groups.google.com/group/legacy-ornamental-mills?hl=en. > > No virus found in this message. > Checked by AVG -www.avg.com > Version: 2012.0.1873 / Virus Database: 2102/4656 - Release Date: 12/04/11 > > -- > You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group. > To post to this group, send email to legacy-ornamental-mills@googlegroups.com. > To unsubscribe from this group, send email to legacy-ornamental-mills+unsubscr...@googlegroups.com. > For more options, visit this group athttp://groups.google.com/group/legacy-ornamental-mills?hl=en. > > -- > You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group. > To post to this group, send email to legacy-ornamental-mills@googlegroups.com. > To unsubscribe from this group, send email to legacy-ornamental-mills+unsubscr...@googlegroups.com. > For more options, visit this group athttp://groups.google.com/group/legacy-ornamental-mills?hl=en. -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
