Last time I saw a Delta, OEM, 1" spindle cartridge, for sale, the asking price was over $500.00 and he got it. An OEM router collet set, 1/4" and 1/2" will be north of $275.00.
If you have them, don't just let them go. They can be worth more than your machine, used, by themselves.
The reversible 3HP WEG motor is a very desirable used component of the Delta shapers also.
