Saw a turning of a segmented birdhouse. Cole jaws had grips that looked to be 2-3 inches in length. Can one buy them or DIY? Thought of making some with appropriate size bolts and rubber or vinyl tubing as padding. Thanks.

Extended grips for Cole Jaws?

That is what I did for a bowl with a recurve edge - long bolts with rubber tubing.
Pat, that is awesome. Did you have any black marks from the rubber tubing? Thinking using clear tubing.
Look on Etsy for SegmentedTurner.He manufactures tall grippers for Cole jaws.Excellent quality.
I made some from the artificial wine bottle corks. Chuck them up on a 3 jaw scroll chuck, drill a hole and put a longer bolt in. They don't leave marks on bowls.
I found a set that I like from Rubber Chucky products - if I remember correctly, they are listed as S.O.S Jaws on the website.
I had also made a set of "extended" jaws from an extra set of cole jaws that I had found at an estate sale that were the same brand as the ones I already had. I just stacked the ones I had on top of the estate ones, added a nylon washer between & used longer bolts - that set up worked ok for me for what I was doing at the time, but I feel safer using the Rubber Chuck ones....
I have tried a bunch of different types of tubing to extend the Cole jaw grips height. I didn't like most of them. I finally came up with a reasonable source to extend the height that is manageable for most of my projects. I use predrilled stoppers. Source for the stoppers that work the best for me is from Widget Co. (https://www.widgetco.com/collections/epdm-rubber-stoppers). The stoppers are predrilled and the bolt for the Cole jaws fits snuggly in the hole. Some people have indicated that the use of black stoppers leaves black marks on the turned piece. I have never had that problem. If that a is a concern and you don’t mind paying a higher price you can get silicone stoppers from Stoneylab: https://www.amazon.com/stonylab-Sil...e-Hole/dp/B0F9YDH8S9/ref=ast_sto_dp_puis?th=1

And a good reason to open a bottle of wine!

I can get rubber stoppers at Ace Hardware.

Another option. Quite a few discussions on this going back at least 5 years ago.
Below is my preferred solution.

An advantage of the extended grips made/sold on Etsy by SegmentedTurner is the stability (and the resulting reduction in vibration of your workpiece), which comes from the combination of a wide base and a solid core (turned aluminium). The wide and rigid core allows you to tighten the tall grip on your piece without the grip deflecting or the piece going a bit off-centre, problems I have experienced (albeit not always) from all-rubber grips held with a 1/4" bolt. The "stiction" on these tall SegmentedTurner grips comes from the relatively thin and firm but non-marring sleeve (some kind of polymer tubing) around the solid core. For the reasonable price he charges (about $40 for 8), I think this is a very good solution.
I wanted longer grips, and came close to these features by turning 1" wide by 2" long dowels, then drilling them through (diameter of the bolts for the Cole jaws) on the lathe, and putting clear vinyl tubing (from Home Depot) over the dowels. If you get vinyl tubing with an inside diameter of about 1", you can turn your dowels to fit. Not as good as the SegmentedTurner grips, but easy / inexpensive to make and you can make them to fit your need.
