Where to buy spindle

[JAZZCNC]

Ice blocks come in standard sizes of 1000 x 500 x 250 and they are not perfect so essentially here I need precision is the edges to make them match each other to glue them together with water. The cnc would do just the sides the top and bottom will be done on a band saw.

So what you need is a surface planner not a CNC router.? Have you considered building a four sided planer on linear axis.?

This would be very easy to build and wouldn't need expensive spindles, tools, or controller and drives, ballscrews etc.

Because you know the linear movement you can just use programable drives that don't even need a PC. Use planner blocks and blades with normal motors for the cutting heads. For linear movement the simple chain drive could be used as you don't need precision just to move a set distance.

If you wanted to automate the process so each blade moves in sequence then a simple arduino could do this.

Just a thought.??
