Spindle Conversion Kit, 3MT

Upgraded my R8 mini mill last weekend and the 3MT spindle fit perfectly with the included spacing ring. The instructions made the whole conversion straightforward and I was back to making chips in under an hour.

The double spindle gear engaged perfectly with my mill's existing mechanism, making the swap straightforward. The included instructions were clear enough for a first-time spindle conversion.

I spent a Saturday afternoon installing this kit, and having the spacing ring included saved me a trip to the hardware store for shims. It converted my old mill over to the 3MT spindle without any guesswork.
