Mark 4/7/520™
Mark 4/7/520™ Self-Study Course
Multi-purpose woodworking machines have been around since 1947. Benjamin Spaulding wrote the first woodworking course in 1956 for the Mark V manufactured by Magna Power Tool Corporation. This new course is designed specifically for the 21st century generation of multi-purpose woodworking machines manufactured by Shopsmith L.P. This course is the only course to be field tested by actual owner/users. It draws from the very best teachers and user experiences to teach the beginner to woodworking as well as the experienced woodworker how to safely and accurately use the Mark V 520, Mark 4, MARK 5, Mark 520S, or Mark 7 perform all 7 operations namely: table saw, disc sander, horizontal boring, lathe, vertical drill press, over-table routing, and under-table shaping. Step-by-step instructions with hundreds of full color pictures give clear and detailed explanations. This course also teaches horizontal routing which was not in the original course. It is designed as a stand-alone course with no requirement for digital media. However, the author has provided supporting videos on his Shopsmith Mark 4/7/520™ YouTube channel to illustrate each of the 50 assignments for the 10 lessons. Delivered to you in a large D-ring binder with sheet lifter, 352 pages, and 10 sturdy tabs. Printed on heavy 100# photo paper for stunning color. Designed to last many years of use. Large 5/16" holes. NOW INCLUDES 12 MONTHLY ZOOM MEETINGS WITH THE AUTHOR!

Shopsmith Jacobs Drill Chuck MC8K26 NOS
From 1972 to 1992 all Jacobs drill chucks for the Shopsmith were made by the Allen Manufacturing Company in Hartford, Connecticut. Today all Shopsmith drill chucks are made in China. I have come across a limited supply of these rare high quality drill chucks. They are all brand new, never used. The drill bits will not fall through the chuck like the current ones made in China. Extremely high quality!

Shopsmith Molder Table Insert NOS
Made from pressure cast aluminum alloy and heavily ribbed for added strength. Coined to ensure a flush fit with the table surface. Useable on the Mark 4, Mark V 510/520, and Mark 7 machines. OEM NOS brand new. Shopsmith L.P. no longer offers this item. I have a limited supply of these inserts.

Shopsmith Disc Sander Table Insert NOS
Made of die cast aluminum alloy with an elongated slot and a beveled underside to allow for sanding with the table tilted. Useable on the Mark 4, Mark V 510/520, and Mark 7 machines. OEM NOS brand new. Shopsmith L.P. no longer offers this item. I have a limited supply of these inserts.

Shopsmith 5-Foot Connector Tubes
These extra-long pair of five-foot Connector Tubes slip easily into the rails of your Mark 4, Mark V 505/510/520, or Mark 7 main table or extension table to give you all the added support you could ask for when working with extra-large or cumbersome workpieces.
Made of rugged stainless-steel tubing to minimize the formation of rust or corrosion and have been designed to work with your existing Telescoping legs and Floating Extension Tubes.
These are no longer offered by Shopsmith L.P. However, I have found a US manufacturer to supply these items to me. Made in the USA.
