I own a Delta shaper model 43-495X (3 HP, X5). Delta claims the maximum spindle size available for this tool is 1 inch (I submitted a question and they sent me a tech support email stating this). Looking around, I find the most popular shaper cutters to be either 3/4" or 1 1/4". While I could get by with 3/4", it would be convenient if I could use some 1 1/4" cutters (but not on a regular basis). So I'm wondering if Delta is just following legal mumbo jumbo and there really is some way I can use a 1 1/4" cutter SAFELY on this machine.
Delta does sell a 1 1/4 spindle but I don't think it's designed to fit in this machine. Does anyone know if there is, in fact, a safe way to do this? I'd appreciate the input.
