New router build advice...

Machining 100mm blanks might be an interesting challenge.First you need to find long cutters and then you need to be sure of getting them to and from the workpiece without digging a trench.

Not with the right spindle and design of the gantry / Z-axis. All the machines I build at this size will cut 100mm depth and retract the tool above the workpiece. However, The cutters are expensive and not easy to find. Work holding also becomes a fun challenge.!

That is an unusual amount of Z axis travel and really useful when you find a taller job that needs doing.I have had to work on 70mm thick jobs on a machine with 85mm of Z travel and it was quite,er absorbing.The comment about work holding is actually something that needs to be brought into this discussion; T slots in the table,threaded inserts or a vacuum system could all come into play.
