When I want to change the distance I move the saddle for say the 1 inch bit I move it the inch then loosen the double locking collar and rotate the work that slight amount I mark the headstock and the hub so I can move it back to the original spot for the next indexing.
That’s how I do spiral indexing outside the legacy router bit sizes Bill From: legacy-ornamental-mills@googlegroups.com [mailto:legacy-ornamental-mills@googlegroups.com] Sent: Thursday, 15 May 2014 6:49 AM To: legacy-ornamental-mills@googlegroups.com Subject: Re: time for a question or two...... @ cole...but what if you want to back out that 1" router bit a bit because it better suits the finished look you are trying to achieve?...let's say to 7/8"...the whole mathematics thing is not usable...i found a grizzly piece that i think will be a nice add-on piece to the legacy and let you index to any cut you want...any repeat from 1 to 360...it will be here in my shop tomorrow and i will begin the not-to-difficult process to modify it to fit the legacy...see attachment...there are 15 degree indents built into the chuck(24 divisions)...the chuck is 3" in diameter...and it has a #2 morse taper...should be interesting if i can pull this off...thanks for the reply...joe On Wednesday, May 14, 2014 4:18:37 PM UTC-4, cole wrote: You move the router the diameter of the bit. Say you have a 1 in. rope bit ,you move 1 in. forward or back it does not matter reengage the router so you can crank it back to the original starting position. you will automatically be ready to do the next start on your twist.
