Is 1/2" bore shaper really only good for router bits?

Topic tags/keywords: shaper raised panel doors

Hadn’t done any research when the opportunity to buy a used Grizzly 1/2” bore shaper (G510z) came up and I jumped at it. Heard shapers were the way to go with things like rails, stiles, raised panels.

So now I see Grizzly doesn’t even sell 1/2” bore cutters to use on raised panel doors.

And the Grizzly rep said that shaper is pretty much only good for running 1/2” router bit sets for raised panel doors.

Is that really true? Is anyone using 1/2” bore shaper cutters for these doors – and if so where do you get them?

Thanks,

Craig

A quick look on MLCS site shows several raised panel shaper cutters with 3/4” bores that come with 1/2” bushings.

Thanks Kenny

But doesn’t putting a 3/4” cutter on a 1/2” shaper spindle kind of feel like fitting a 1/2” router bit into a 1/4” collet? I hope someone who has experience in doing this speaks up so I can get on the bandwagon.

Not sure I have the 1035, it comes with the 3/4” spindle and a collet adapter for router bits?

The bushings should make it work just as a 1/2” to 1/4” sleeve adapter wouod in your router bit example.

Thanks Ken I do get what you’re saying however if I bought a little router that wasn’t supposed to take anything bigger than a quarter inch bit something just tells me it wouldn’t be a good idea to find a three quarter to quarter inch adapter and run half inch bits. But maybe I’m just looking at it wrong

Don’t get me wrong, I wasn’t advocating one way or another, I was just giving you a suggestion on where to get cutters. I don’t own, nor do anything that requires, a shaper. I have a 3-1/4 hp router that does everything I need it to. As a machinist though, I can tell you that the bore size in the cutter will have little affect on the performance as long as it’s a quality cutter with a precise bushing/adapter. The spindle size provides your stability/rigidity. As long as the cutter isn’t too big for the speed and hp of your motor, I don’t think you’ll have any problems.

1/2” spindles were sold for the home workshop for years. I’ve been told that they will accept 3/4” cutters with a bushing. I bought a vintage Rockwell years ago and keep meaning to try it out. The fence is massive (and split). The motor switch has a forward/reverse thing. The cutter itself moves up/down easily. Thinking about getting a few cutters for round over work…maybe some ogee work too. Probably requires a few passes on hardwood but no different from a router in that respect is it?

I had one of those, but never got much use out of it. That’s a pretty light duty shaper for large cutters. They do work fine with router bits, though some would say the rpms aren’t high enough. One problem with them is that they give you very little adjustment range vertically—only about 7/8” I think.

After that shaper, I went with a big router in a table for a while, then back to shapers, first Grizzly 1.5 horse model, then to a Jet 2 hp that I like very much (both from CL, naturally). I do use router bits in mine quite often, and find the results satisfactory. Two h.p. with an induction motor, vs 3.5 from a router’s universal motor, is like comparing a clydesdale to a shetland pony. Both the larger shapers had bigger spindles, more appropriate to large cutters.

I have a Rockwell 1/2” shaper and use it for moldings, picture frames and joinery. The shaper is quieter and reduces a lot of the vibration (cast iron table) that a router table would have. It can’t do all that a router mounted under a table can do, but for certain jobs I have a router. I feel that both have their purpose in my shop. Try the shaper, I don’t think you’ll be disappointed.

The bigger the spindle the better you are but dont look at the green bear as the only supplier for cutters. Also you can reduce 3/4 cutters to 1/2. You also may be able to swap the spindle to 3/4.

Shapers are great and there is no other way to go. You can run bits on them but that is like saying you can sit in your car in the driveway and listen to the radio. Sure you can but you can drive it at high speeds down the highway and listen to the radio too. I ll take the high speeds w/ radio.
