Hollow a seat

Have a circular wooden seat, about 20" diameter that must be hollowed to a depth of about 1/2" in the centre. Like a very shallow dish. Any ideas or jigs. I do not feel like chisel work. Thank you all and best regards. Johann

I have used a paint stripper disk on a 4" grinder.

Thanks. I have seen these scooped seat. But that is different to what I have in mind. I agree, the stripper disk can do it but to get it symmetric will be difficult. Maybe some other reader still pops up! Thanks anyway. Much appreciated!

Look up chair seat carving router jig. There are a lot of cool ideas. I am not sure of how exactly you need this scooped, but that may help.

I can't find it, but I saw a guy use a pendulum style jig, with a router on the end, to get a perfectly round dish out of a piece of wood once too.

you need a good eye....

A good eye, depth holes and a Kutzall wheel in an angle grinder.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

I've never done this before, but how about your circular saw. Half inch isn't that much so set it and do multiple passes. Just hang on to it.

Its' never hot or cold in New Hampshire... its' always seasonal.

Consider which way the cutting force vector is being applied,haha.

Seriously,think about which way the "toolhead" is cutting.Yes,there is a matter of convenience,IE...."I have this pce of equipment,and don't have that".But lets say you had an angle grinder(AG) vs a router.The AG will cut in vertical and horizontal,AND anywhere in between.The router(and not picking on routers)basically cuts in one plane with others limit'dly(sp),as it applies to scooping.

So,which is more important.....

The datum line of the circumference or the depth control?Which section is easier to "fix"?Or fine tune?Which tool do you(OP)feel more comfortable with?

Those who say it cannot be done shouldn't interrupt the people doing it.

I think the only way I will get the effect that I want is to put it in the lathe and turn it!

Let's see now...

We have routers, the lathe, a CNC, hand tools, and the table saw:
