I think spline drives are actually part of the motor shaft.Don't think they are a user replaceable part-the wagon wheels are user replaceable.Extra wheels are available from a Waring Commercial products dealer or a large well stocked restuarant supplierr.I am afraid the new "Rocket Blender" shown today is a wagon wheel one-wouldn't be surprized.I am looking for an older Spline drive one.
On the Blendtecs-these are even more powerful than the Vita-mix.their "Titan" model has a 96 oz cap jar with a blade that is over 5 in across.the machine also has a NEMA 20A plug.Its a SERIOUS blender.I have one in my collection and use it along with my VM's.Its said the blendtecs crush ice so well its turned into SNOW!!and you don't need to put any liquid in the Blendtec jar to crush ice.Tried it once-WOW!! Awsome!any of their machines can crush ice to snow.I wouldn't do the crushing too much-Blendtec has ultrasonically welded blade assemblies in their jars-have seen some small cracks in some of mine.The blades in those are not user replaceable.VM's are to their credit.In many of my smoothies I have blended whole frozen strawberries with no problems in either the Blendtec or the VM.they evn crush the strawberry seeds that no other blender will do.No clumps of strawberry seeds in the bottom of your cup!Its said crushed strawberry seeds are good for you.
