I just acquired a used Grizzly shaper with a 3/4 inch spindle. New cutters cost a fortune, so I am looking for used cutters in decent shape.

I would like the basic profiles as well as any classical or period molding profiles.

Have folks here used the interchangeable cutters whereby you can use one arbor and exchange cutters?

How about grinding them yourself? – that looks rather tricky, but would certainly be cost effective.

I also need to make a fence, as this does not have one – I’m sure there are abundant plans and will do that research soon as I get a chance.

I you want to grind your own, it can be done with the correct machinery, but it is not an eyeball procedure.
Each blade has to be ground precisely the same, or you are going to have one blade doing all the cutting and
getting dull, and those nice crisp corners and curves are a pain to make. I bought a used shaper that
included a few cutters, including a couple that someone tried to sharpen themselves, they were good
paperweights. Grizzly has about the best prices on shaper cutters.

Thanks very much Gus.

Seems like good advice.

I’m wondering if a kit is a good idea to save money: one arbor with interchangeable cutters.

Bill, con grads on the shaper. Im assuming it is their 3hp machine being it has a 3/4 spindle (will accept up to a 1 inch).

Were i you i would forego the insert cutters for a while until you know what you’ll want.

There are quite a few out there.

Grinding your own knives is not too difficult with a suitable setup.

In my experience, the best bang for the buck are the grizzly cutters.

I have a few delta sets from thirty years ago that never held an edge as long as the grizz. cutters i use.

They have quite a few profiles available and also have an insert head for a one inch spindle that is very reasonable. Profiles are sorta limited but they also have blanks i think.

Enjoy the journey my friend !
ps. (don’t count on insert cutters to save you money)

Well, I rechecked and it’s actually a 1/2 inch spindle, 1/1/2 HP model, dated 1990.

Thanks a lot ‘Cabmaker’ for the input.

What sort of “setup” do you refer to for grinding my own knives? I assume you refer to certain grinding stone configuration and grits? The concept seems difficult: getting each cutter identical might be a bit tricky.

Profiles of interest would be strictly larger period moulding profiles. I can do coves and most small profiles fine with my router. I bought a copy of Lonnie Bird’s Shaper book and that’s been pretty helpful, albeit not too detailed.

Hey Bill, check out Dan at ‘Oella Saw’. He is just south of Baltimore and sells and sharpens shaper cutters among other things. He is very knowledgeable and helpful.
Good luck.

Thanks Kimball,

I’ll check him out.

I’m new to using a shaper, so I appreciate the advice.

One good place to get cutters is at industrial auctions, commercial auctions (cabinet shops and millwork) and also closed school shops. Cutters usually go pretty cheap. If you buy any they need to be checked out carefully before using them. We acquired a lot of cutters this way.
