Hi everyone,

I recently ordered a Robland NX410 combination machine, which includes a slding table saw, jointer/planer, and a shaper that I am eager to start using. That being said, ive never used a shaper and am a bit terrified. I have a couple questions regarding the usage of it:

1. The shaper spindle is 30mm, which makes it hard to find cutters in the US that size. I see that I can get 1.25" cutters and metal sleeves to adapt it to 30mm, however the Robland manual says not to do this. Does anyone else have experience using adapters on shapers to reduce the bore? Is it safe to do this?

2. I would love to get this Amana adjustable groover. I am looking to use it mostly for cutting tenons and grooves. Robland sells a specific table for tenoning, but it is quite heavy and an extra $400. Can I get by with just clamping stock to the fence on the sliding table?

3. Any other things I should be aware of/consider when it comes to set up and safety?

Thank you!
