{"product_id":"woodriver-professional-pen-turning-mandrel","title":"Professional Pen Turning Mandrel","description":"WoodRiver® Professional Pen Turning Mandrel allows you to switch between small turning projects of any length with a simple loosening and tightening of a nut. The professional pen turner's mandrel is self-centering ensuring no more off-center turnings and\/or spacers for short length projects. A totally new concept, this mandrel features a collet that ensures that the shaft is always exactly centered on your lathe. Because the collet body is hollow, the amount of mandrel shaft extending from the collet can be varied for turning everything from key chains to larger pens. The locking nut and collet work like the collet in your router, just loosen the nut and slide the shaft in or out to the length you need, then tighten. The small end of the collet body features a 5\/16\" thread that allows you to pass a bolt through your headstock and, with the mandrel shaft removed, the collet assembly can be used as a 1\/4\" collet chuck!\u003cbr\u003e\u003cspan\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePrecision machined to eliminate off-center turning\u003c\/li\u003e\n\u003cli\u003eCollet chuck action\u003c\/li\u003e\n\u003cli\u003eEasily tighten with knurled nut\u003c\/li\u003e\n\u003cli\u003eCollet assembly can be used as a 1\/4\" collet chuck\u003c\/li\u003e\n\u003cli\u003eAdjustable mandrel can be used to turn a single pen section and avoid harmonic vibrations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\u003cli\u003eTaper: #1 MT\u003c\/li\u003e\u003c\/ul\u003e\n\u003cb\u003eWhat's Included:\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e(1) 1\/4\" collet\u003c\/li\u003e\n\u003cli\u003e(1) Collet nut\u003c\/li\u003e\n\u003cli\u003e(1) Mandrel shaft with washer and nut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cb\u003eWhat's Needed:\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\u003cli\u003eBushing sets must be purchased separately\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\u003c\/span\u003e","brand":"WoodRiver","offers":[{"title":"#1 MT","offer_id":43407293710474,"sku":"145998","price":34.99,"currency_code":"USD","in_stock":true},{"title":"#2 MT","offer_id":43407293743242,"sku":"145997","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0616\/1711\/1178\/files\/145998_000_001.jpg?v=1762270459","url":"https:\/\/www.woodcraft.com\/products\/woodriver-professional-pen-turning-mandrel","provider":"Woodcraft","version":"1.0","type":"link"}
