Open Segment Project - Acoma

Turned and sanded the ID up to row 18 this morning.
Got rows 19, 20, 21 & row 22 is on and drying. After facing I put on 23 & 24 tonight.

The ID starts pulling in at 24 so it looks like it's time to finish turn and sand up to 23.
It'll be slower from there as I don't want the ID to get to small to get at the previous rows so I'll put on two row and then finish two rows. We are getting close where I get to try a solid ring with the new fixture.
That should be interesting

Bob, got your zip file for the sketchup drawing. Looks good.

By any chance do you have a parts list for the jig? I am looking to build a non motorized (not pc controlled), jig this summer. Mainly interested in your parts for the vertical rack and the stops to hold in at heights.

Mike for the vertical rack I used Linear rails and bearings from Title: Phidgets Inc. - Unique and Easy to Use USB Interfaces

The two rails are: Title: Phidgets Inc. - LMN4002_0 - Linear Shaft 16-1000mm they were 10.00 each
The four bearings are: Title: Phidgets Inc. - LMN4219_0 - Flanged Linear Bearing for 16mm Shaft they were $4.10 each
The Rail/shaft supports are: Title: Phidgets Inc. - LMN4223_0 - Shaft Support (Pillow) for 16mm Shaft (2pcs) you need four of then they come in pairs so you need two packs at $3.55 each

I put a toggle clamp on the side for easy temporary clamping, it puts some side push and moves the support a little so I only use to make adjustments once those are locked in I release this temporary toggle. For the main lock of the vertical rack I just use a T-rail from Woodcraft and a angle bracket

I can take some close up pictures of things if that would help.

Also, if you pull the sketchup drawing apart you will notice that the 3/4" MDF base is two layers of MDF, I wanted the base really solid as I put two 3/4" flanged bronze bushing in it of the shaft to turn on. Not shown on the sketchup drawing is a third 3/4" flanged bronze bushing separated from the base. In between I have my timing gear for the attachment to the stepper motor
 
Thanks Bob for your list. It will help in my build. I know when I do mine it will be a manual turn.
I have been looking at the vids from this site.: I basically want a pretty simple jig to build. Your list of materials will help.
Title: Open Segment Jig
 
Mike an option to the index plat are timing belts. You count the number of cogs on the belt that you want to use and then make a disk that fit it.
Here are a couple of pictures:

Bob, your piece is looking great. For me watching the pattern come out almost feels like watching my kid grow up :)

Tom the more I work on this one the more I'm liking it. The pattern and colors are coming out great. I'm hoping I picked a profile good enough for the pattern.

Row 26 is on and it's pulling in.

Looking very good.

Is your open segment jig nuclear powered? Noticed the radiation sign.:eek::)
 
Some inside turning this morning on the inside corner.
I didn't sleep well last night thinking about this in the morning

Debating between 60 or 48
