    Could I use this in the 3kw HSD spindle? With the half inch collet?

    Or is this just for routers?

    You will be better served by investing in longer, heavier tooling. When you use "extenders" you're most certainly introducing additional runout which is not a good thing for precision machining.

      NO NO and Even a BIG Hell no,

      forst ask yourself Why ? when i do DEEEEP cutting i look for bits to accomodate the depth or a strategy for doing this

        Ok thanks y'all. Really appreciate it. Any great sources for extra long bits? Toolstoday? USRoutertools?

          I check usroutertools first and then the internet second. I've bought some longer bits from them that met my needs but they don't have a super large selection.

              Many thanks again y'all. So the reason for my question was watching this video.

              https://www.youtube.com/watch?v=i5ojCcb-7GA

              Does there already exist some handy dandy calculator / optimizer for determining the maximum depth and slope of a dish like this given the dimensions of your cutter and spindle? Or do I just have to tackle this with trail and error / math?

              I'd love to be able to enter into a calculator the cutter stickout, cutting length, and dimensions of the collet and spindle to generate a no-go zone for a dish.
              cheers

                When it comes to deeper bits i have had to look at machinist bit sites. i have some 4" LOC 6" oa taper ballnose.

                If I was doing bowls i would use a .375 ballnose with a 8 % or less stepover

                The thing is to know enough of the simple math to cut

                deep enough and not have collisions with the collet and the wood yor bits and wood, never thought about a calc or App but when it comes to the cnc I would always check my own math anyway

                I have seen quite a few worthless apps and calcs come and go mostly go

                  Bowl effect using large ballnose, Note the clearance space (vcarved+ so the bit had clearance)

                    Thanks a lot, really appreciate it. What machinist bit site are you finding a 4" LOC 6" OA taper ballnose at? I had a look at a few sites that I know of and can't find any with that big of a LOC.
                    many thanks and take care

                      One other factor for longer tooling is clearing the material...your Gantry has a maximum distance between the bottom of the collet and the machine table plus spoilboard. Your tooling has to be able to clear over top of your material during tool measurement and rapids...that clearance can be set to a minimum in your software/design, but there's still a hard limit with available space. I ran into this big-time when doing some joinery cuts on my SR-44 whereby I was physically limited to about a 1.5" LOC plus a tiny bit below the collet because of material thickness on top of my spoilboard. For my application, these mortises worked ok, but ideally, they should have been about an inch deeper.

                      I do use a .375" diameter end mill with a 1.75" LOC for deeper cutting when it's possible, such as for cutting out guitar bodies or trimming the ends of thicker charcuterie boards.

                        Magnate.net has the best assortment of any type of bit that I have found. I have purchased many of their ornamental bits such as different sized barley twist etc. I purchased a long bowl bit which is basically a four inch shank with a ball type carbide bit for bowls but I have never used it. They are definitely the best place for odd or legacy type bits. When I first starting using my recoil I was really into the potential uses for projects so I bought hundreds of dollars of bits from them. Then other projects for family and friends came along mostly furniture stuff and it all went on the back burner.

                        I find the problem with the recoil is when you use it regularly it is fairly easy but when you get away from it for a few months then it is like staring over to remember how to think about the design, wrapping and toolpaths. I am trying to get back into it now but I am back to square one with rounding etc. The other issue is that I can't help but think that I can do much of what I want on my regular wood lathe much faster but I paid good money for the recoil and I want to use it and I am retired and there is no reason to hurry. One thing that the recoil can do that me and my regular lathe cannot is repeatability. If I had to produce in a timely fashion, I think I would default to my regular lathe but I do not so it is moot. The flat CNC work and the recoil is two different machines and thought processes IMHO and there is a lot to learn and remember about both. FWIW.
