Amen to that. Every tool is dangerous if used wrong.You learn good practices and safety real quick when there's a 4 foot diameter blade, exposed flat belt pulleys and logging hooks.

Neither did routers, or table saws but both can be dangerous tools in the shop/worksite.

Actually lack of understanding of what can go wrong with certain tools is what leads to many accidents. An experience wood worker learns to read the grain of a board to get some idea of how the wood and the saw will interact, a tool is a tool.Tools are NOT dangerous. It is the operator that IS !
I have a very healthy respect for what my 5hp Grizzly Cabinet Tablesaw is capable of....My father bought me a table small saw many years ago, and told me that for his sake I should be careful, because he didn't want to be the one who had to tell my wife I'd cut a finger off. He also said the saw is safe to use as long as you're just a little nervous each time. Not terrified, but just that little bit nervous.
Very easy way with a band saw.
This is what I do for centering rings. Works perfectly with minimal work to be done afterwards.Thats great for general circles but for centering rings which need to be very precisely fitted there is still a lot more work to be done.
Mine fit better than most I get from rocket manufacturersThats great for general circles but for centering rings which need to be very precisely fitted there is still a lot more work to be done.
They should fit better, you can finesse them to a perfect fit, rocketry manufacturers tend to make them a bit under on the OD and a bit over on the ID so they slide on/in easier otherwise people whine about how much work they have to do to make them fit. I no longer use flycutters, and the bandsaw or scrollsaw only for rough work, router templates make almost perfect rings straight off the router table.Mine fit better than most I get from rocket manufacturers
Maybe what you are buying but 1/4" baltic birch from my supplier is about $25 per sheet and it makes lot of centering rings from a 60"x60" sheet. See if you can buy from a local cabinet shop, they use lots of 1/4' baltic aka 6mm for cabinet drawer bottoms and the like.I usually 3D print mine (although I have a CNC, plywood is more expensive than filament)

That's very nice for bulkheads, but how do you cut the inside hole dead-on center?Very easy way with a band saw.
Drill bit through the center hole. Easy peasyThant's very nice for bulkheads, but how do you cut the inside hole dead-on center?
(OK, I see a way. I'll reveal it later, after hearing others' answers.)
I use a nice forsner bit.Or a hole saw. But hole saws tend to be sloppy.

I am usually making 4" of with 38mm or 54mm motor tube holes.What tool you use is based on what thickness material you are cutting through... and what type of material the centering ring is.
The thicker / more durable the material... the easier it is to cut. But if we're talking about lpr, and basswood or balsa, not destroying the ring is the tricky part.
The reason I bring this up is.......
Please, tell us more. What diameter drill bit are you referring to? A BT-50 would need a 1" drill bit. If you're using a standard 1" twist style drill bit to make a centering ring it will destroy a thin LPR centering ring.
Even a forstner bit will destroy thin basswood / plywood.

Autocorrect bit me again. 4" od. For 4" body tubes with 38mm or 54mm center holes for motor tubes.So your making a 4" thick stack of centering rings?
