No chance that aluminum knives will hold up.
There are companies that will make HSS knives to your specs for a very reasonable price.

I have a nice accurate CNC router. I have no trouble machining out the locally supplied 5083 alloy plate from a supplier her in NZ to any shape. Woodwork wise, I have been making doors and windows out of western red cedar for a while now and have been asked to replicate a profile which is custom. I use my router for a lot of the work including mortising and mortising in the locks.
Is there any way I can machine a profile out of 5083 alloy for my spindle moulder cutters? And then perhaps for my tenoning head. Is the alloy too soft to sharpen for timber use?
It would be perfect if I can draw up my own spindle moulder profile cutters with my CNC router, then profile them sharp and install them into my spindle head. Anyone done this before with alloy which is best for machining dry? Perhaps get the 5083 hardened to hold an edge? I am not going to try to cut out HSS or tool steel I know that it wont work I dont have a cooling system just a mist which I hand spray.
Please can someone more qualified in metals give me some advice? My only other option is to cut out a profile and pay someone to manufacture the cutters out of proper cutting steel.
Regards
Boyd

Hi. Thats a shame. Although I do know there are some extremely hard alloys out there but unmachineable on a high speed spindle without cooling. I have just found though that yes, you are absolutely correct it is cheap and easy to have knives and cutters profiled and sharpened!
I had a memory of spending almost a thousand bucks on a tennoning head!
Kind Regards
Knives are made with a grinder using flood coolant. We have a knife grinder in our shop for our moulder.

I found a guy who can do it. And even better is that he is offering work to me to design and cut out the blanks he needs for certain profiles with my CNC router. So a win win!
