2 V 3HP routers
I'm not a regular enough router user to answer this question for a mate of mine.
Said mate is about to go into production mode (cutting amongst other things slots and cabinet corner joints in ply and hardwood) using bits mainly around 20mm but some will be up to 60mm in diameter and would like to do this using a router (in a table) and needs to decide between using a 2 HP router (which he already has) or buying a 3HP router.
Any suggestions would be welcome.
Thanks

I have a Scheer 3hp router that accommodates 70mm raised panel cutters without any problems, I don't think I would want to go much lower in hp, for production in my opinion a spindle moulder would be a much better option.

2hp can probably handle it; I have run 3" diameter panel raising bits (the bearing version of this 2 Flute - Raised Panel Bit - Carbide Tipped - Carbitool ) by hand with a 1700w fixed speed Hitachi in US Oak and Walnut with no issue. I don't think the extra 200w is make-or-break, just need to listen to the motor and adjust the feed to prevent it getting bogged down.
It's a good excuse to upgrade and probably a good idea, but not strictly necessary.
EDIT: Obviously a moulder would be best, but that's a MUCH bigger investment and certainly not practical for most DIY users

I think the key to this question is in the "production" aspect. I don't suppose for one moment we are talking thousands, but even twenty or thirty is enough to warrant more attention.
For thousands, at least a spindle moulder is the order of the day. but more likely a dedicated moulding machine with multiple cutters. For twenty or thirty I would expect to use the largest router I could access within reason, bench mounted and with variable speed. As the cutter diameter increases the speed should be reduced to maintain an optimum peripheral speed.
I note that Elan used a hand held, fixed speed machine but he has huge experience in this area. I would not recommend that most of us try this. I would also suggest it was not his first choice of operation. The potential for a large cutter to grab and cause damage is more than I am willing to risk both to the work and myself. So for me a large HP router with variable speed control, mounted under the table is the way to go.

PS. If only a smaller machine is available, that is acceptable. You just have to feed the material more slowly.Bushmiller;
