I know this is wood, but the machine I want to build is metal, so I hope it's on topic. I have recently bought an older house, which needs quite a bit of work doing -mostly wooden windows & doors that are rotten. I've been looking at what kit I need to make replacements and it seems to be a bench saw, probably a sander and a spindle moulder (or router and router table). The saw and sander I can buy from the local machinery dealer for a reasonable price, but routers/ spindle moulders seem to be big money -and the cutters even more so.
It seems to me that all I need is a rotating spindle with a flat table built on to it. Then a fence to set my depth. For cutters I was thinking a 50mm or so diameter boss with two slots 6mm wide to take blades ground up from HSS or hardened GFS. These would be held in place with a couple of screws. I know it would be a bit of a hassle changing cutters, compared to just unbolting one cutter an putting another one in, but the cost saving makes it worth considering.
Is this possible, or should I forget it and just keep looking for a cheap secondhand machine (but then I'm still buying expensive cutters). Has anyone made a machine like this, if so do you have any words of wisdom?
Thanks Kevin
