Thanks, Don. Making my own HSS cutters was what I was thinking would be the thing to do. I'll have to make a riser to raise the scroll chuck to spindle center height but as has been said, that should be straightforward and can be done as simply as with a block of hardwood. My lathe is a Robust American Beauty, and with its' 25" swing, I imagine the cross sled will need to be raised significantly.
It seems to me that it might be handy to have the cross sled riding on some sort of micro-adjustable turntable which would facilitate orientation of the piece being milled. I don't even know what such a thing is called. Any ideas where I might be able to buy such a thing?
Y'all have been very helpful and I appreciate that. My thinking right now is to make a DYI JaHo. If, in the future sometime, I feel a need for a rose engine, I'll have to consider the MDF version.
Regards,
Glen
