Ken, I have 1/8, 1/4, 3/8 and 1/2" roundover bits so I can match whatever thickness of wood I have.

It's usually best to perform the round over in a succession of increasing depths. Woods like cedar, which splinter easily do not react well to full round overs right away, especially for example with a 1/2" R bit.

A table-monted router is probably the fastest way for rounding lurebodies, but certainly very dangerous. Machining handheld lurebodies with a table-router is asking for an accident to happen. At work (a plastic machining company) we have several table-routers with custombuilt safetydevices, but routering small handheld lurebodies is deffinately abit scary anyway. Am planning to machine some sort of device to secure the lurebody when routering it but I need to get some sort of non-slip rubber so that the lurebodies easily are securely fixed without too much force needed.
For handmade lurebodies a japanese radius plane could be of use, Iv e recently ordered a small one, 160x26mm with radius of 18mm. It will be intresting to see if it works, Ive read that radius planes like this are used when building custom music-instruments and stuff like that.
Heres a pic:

NC, it looks kind of big, for small lures (let's say under 3" ) , and how are u going to fix the lure for this operation?

I'll add my 2 cents becasue i've been trying many different methods.
Router table is deffinitly the fastest way to go. Are they dangerous?...no not any more than any other tool as long as you respect the tool you'll be ok.
My wooden lures are 4 inches long and I'm not so interested in rounding them out as much as I am in getting all of the sharp corners rounded.
Recently I have been experimenting with a lathe. My baits are symetrical so the lathe is well suited for this. I start with a 60 grit strip of sandpaper and work my way down (or up) to 120 grit. I cut the sandpaper into strips and run it along the bait as it is spinning on the lathe.
As long as your bait is symetrical and is centered on the lathe the results are very impressive. I'm inclined to say better than what I was getting using a router. Not much chance of getting an accidental manicure either.

Pikeman... most of my baits are around 200mm long, so i dont think its any problem with this "small" radius plane. Im planning to manufacure a "clamp" (dont know if its the right word?), the lure is fixed between two custom-shaped acrylicparts that got non-slip rubber... kind of hard to explain for me in english IŽll post a pic of it later on.
Mr. J... your deffinately right, respect of the tool is the key. Your lath and grit-paper method sounds great.

Not that I want to contribute to anyone losing something important like a body part, but Woodcraft has their carbide anti-kickback roundover set on a heck of a sale this weekend, with free shipping possibly to boot, I don't have them but seems like a sweet deal.

Go to Home Depot and look at their oscillating belt sander/spindle sander. Their tool brand is Rigid. It uses 4X24 belts, which are standard and easy to get, and have enough surface that they don't load up/wear out for a long time.
I shape bigger baits using 36 grit, and it removes matl. quickly. Much easier than a router, and I have more control. I have nothing against routers. I must own eight. But the sander is quicker to just walk up to and use, a lot safer, and I can change belts and go from roughing out to finish sanding in a heartbeat.
Anyway, it works for me. And the Rigid machine didn't cost an arm and a leg. Just an arm. )

It's a shame we can't get this thread into a tutorial (M'sST) there are so many safety DONT's, and brain storming DO's, to questions which are basic and fundamental, to lure making here in one thread, it's not funny - PLUS- "The Australian Wheel' would be in stone for all to eventually take on board with fingers in tact. There are so many great ideas/ tools buried in threads on TU, you just have to read every one.pete

Did you see this one?

After going through this thread I noticed that hand held cornering tools were not really mentioned. There was one mention of a cornering plane but this tool seems a bit more convenient since it has multiple radii. http://www.leevalley...682&cat=1,42524
They carry another cornering tool but it does not have as much options as the above set has. Anyone try this method yet?
BTW the pneumatic sanding drum posted previously is ingenious, now I'm debating if I get that or the above.

The problem I've found with that kind of hand held edging tool is that it catches the grain whenever there's a slight change in grain direction. This is because there is no depth control.
Before you try that, get a block plane with an adjustable throat, and give that a try.
A block plane and a sanding block will give you control, and remove wood fast enough.
But Pete's radiused sanding wheels are the best idea for consistent, safe rounding over of blanks, short of the mutiple blank approach with a router table.
I can envision stack of discs glued together and mounted on a shaft, with several different radius'. Sort of like a step pulley, but all the same diameter.
The only drawback I can see is changing the paper.

Yes, we use a custom jig that mounts to the top of the router table. We have different size quarter round bits for different size lures. Very fast, and accurate! The best, however, would be a CNC machine.

I would start with a square blank start cutting the shape of the lure roughing the shape out while its still attached to the square blank.
Then you can use the square stock as a handle to shape route and get the body true. Then cut the blank off.

If rounding over flat sided baits, give double sided tape a try. Start with router and small round over and progress to desired shape on one side. Remove bait from tape and turn lure over using a new piece of tape. Don't try to reuse the same tape. Worked in our cabinet shop for small moldings and parts. Important, always go counter clockwise around the lure. Musky Glenn

Here is the way I round my musky baits and it works great. There is a rubber sheet material that is manufactured in many different patterns and colors. It all has holes molded into the sheet with several patterns available. This material is sold in hardware stores as toolbox liner. You can also buy it at department stores or at the dollar stores where is sold as shelf liner for your kitchen cabinets. You can also buy it in the form of placemats for your kitchen table or coasters for your beverage container. Now, cut out a section of the rubber sheet material that is 3 to 4 times bigger that the biggest lure you make. Next, glue that piece to a board with contact cement. (It is important to glue the rubber sheet to the board). I use water based contact cement so it does not dissolve the rubber. Now, you have a very "grippy" surface to lay your baits on while you round the edges with your router. It is amazing how that rubber sheet holds the bait with just friction. This is very safe and quick and allows you to keep both hands on the router. I usually run 1 screw through the rubberized board into the work bench to keep the board from sliding around. I originally bought this stuff because of the interesting pattern of holes in the sheet. The stuff sold as shelf liner has just the right hole pattern to make an excellent walleye pattern if you use the right paint combo.

Fish with teeth, That shelf liner trick works better than double surface tape, Ease of application. Musky Glenn
