I start by making one from hard maple, osage, or black locust and see how that works.

Would this work? https://www.woodturnerscatalog.com/p/112/5507/turners-select-No-Lock-Spindle-Washer?term=washer+lathe+chuck&term=washer%20lathe%20chuck

I've had one on my lathe since about 2003. It has worked well for me.

Joe Zarnitz, are you looking for something to allow you to space your chuck out a bit from the headstock? Or looking for washer to help keep your chuck from getting stuck?

Brice asked the same question I was going to ask, why do you want or need the washer. I had some of the hard plastic washers from Craft Supplies, and eventually lost them, and never bothered to replace them.

As said by David, I use one from CraftSuppliesUSA to prevent my chuck from getting stuck on the headstock. I ordered several and have all in a drawer except the 1 I use.

the talon and nova chucks only seat on a small lip not all the way up leaving a 1/8'' space----where as the faceplate from laguna screws all the way up tight---the opening lip is smaller allowing it to go all the way up---

Joe, I assume you use a direct threaded Nova? My five Novas all have inserts and seat just fine. That doesn’t help your problem, but might explain why it is happening.

I cut my own from a plastic milk jug. These have worked for me for 20 years!!!

I know a lot of people use the plastic washers, but not me. Find a steel machined washer. My experience is the plastic washers will compress differently causing some misalignment. It is not much, but those washers are unnecessary. It is also a belief that the plastic washers prevent a chuck from getting stuck. Never “snap” spin a chuck or faceplate on. Keep the threads lubricated and turn it by hand until it makes contact and then use the removal tool to snug it up. I have never had a problem or a chuck get stuck using this method. You can also search spacer instead of washer.

You might try a community college or high school that has a machine shop. I needed a 5/8 thick one for my Baldor grinder to move the wheel far enough so the nut would seat. It wasn't too expensive.

Same here. Years ago I heard about these washers and got one. Found out they made the precision sloppy and got rid of it. I've heard a number of pro turners say don't use them. Chris Ramsey (cowboy hat turner) even took a brush and cleaned off the threads and seat of the lathe and chuck for the best precision. I use a wrench to remove a chuck.

I both agree and disagree with the "never snap spin" to fasten a chuck. I do that every time (just the bare chuck, never with a piece mounted). I think the trick for success is developing the mystical calibrated wrist motion. Not enough and the chuck might not stay on. Too much and you weld the chuck to the lathe. I flick about 1/8 turn with a more or less gentle flick. I've never had trouble removing a chuck with the wrench and never had one unwind. I don't know how to define "more or less gentle" and I have no idea how to teach this to someone, especially to the Hulk's little brother.

But as for machining a custom washer it doesn't seem like it would be too much work. Joe Pieczynski does this to make some washers from some extremely thin stock in one of his excellent videos (my favorite youtube machinist!) He uses the tailstock to clamp the stack tight.

John, done right you could spin the chuck as you described. If it works then that is all that matters. Many including myself have the tendency to “wind” up and spin. The other John Jordan taught me to do it the way I described and has worked for me.
