I repair single or double bearing quills, drive sleeve assemblies, speed control mechanisms, motors. I can convert your gilmer drive to poly v. My services are for Shopsmith Mark V only though I have worked on all types. Whether you want me to look over parts for evaluation, or if you want a new "pork chop" or new bearings installed, I can help you. Shipping components to me for service saves you a lot on shipping costs if you are comfortable doing the disassembly, cleaning, lubing and reassembly yourself. I will work with you any way I can. Prices vary by item and service. Call for pricing or from time to time I advertise this on ebay.
