There is a on this adapter. a bore of 625 On one end, 1/4" deep, and a 1"-deep on the other. On the other end, there's an 8 x 1" deep male thread.
This was a perplexing issue for me, and it took some time to figure out, so I hope this information is useful to others who own Shopsmiths. br>br>The Shopsmith Mark V features a 5/8" non-slip grip. Tools are held in place by a set screw on a threaded spindle. As a result, in order to use NOVA G3 chucks on your Shopsmith, you'll need an adapter. NOVA produces two versions of its G3 Chuck, which is a bit confusing. (The FAW on the NOVA website has a detailed explanation of the differences.) Before you go out and buy a Shopsmith adapter, figure out which version of the G3 you have. br>br>In order to use the G3 Reversible Version Chuck (NOVA 48232) included in this 30th Anniversary G3 Kit, you'll need to purchase an adapter that connects the Shopsmith's 5/8" spindle to the chuck's 1" x 8 TPI threads from a third party. Penn State makes a similar adapter, the PSI L5818, as Dennis mentioned earlier. One is also made by Hurricane Turning Tools. This type of adapter isn't available from Rockler. NOVA also produces a version of the G3 that is not included in the 30th Anniversary Kit.br>br>br>NOVA also produces a version of the G3 that is not included in the 30th Anniversary Kit. The Insert Version G3 Chuck (NOVA 48202) is the name given to it. Threads are 1 1/2" x 8 TPI on this model of the chuck. The Insert G3 Chuck (NOVA ISNS 71029) comes with an adapter from NOVA. The Nova Insert/Adapter, 5/8" Plain Bore, Rockler Item 43743, is available from Rockler, but it will only work with the Insert version of the G3 Chuck, not the Reversible G3 Chuck included in the 30th Anniversary Kit.
Yes, the l5818 fits a 5/8 shaft,,,Shopsmith has a 5/8 shaft,,,the l5818 thread size is 1" x 8tpi,,,you will need to match the threads to the thread size of your chuck.
The adapter size you're looking for is not available from us. You might want to consult your lathe's manufacturer for recommendations.

I turned it on, closed the shopsmith, and the lathe chuck unwound from the adapter as it was winding down. LUCKY for me, I had a hockey puck in the chuck's jaws, and as the chuck unwound, the puck pressed against the drill bit I had in place, preventing the chuck from flying off. br>If this had gone flying, the sheer weight of it could have easily killed or maimed me or anyone else in the vicinity. I believe that with the force, it could easily go through a wood wall and damage whatever is on the other side. br>I'm not sure what to do to keep this from spinning off when winding down; please feel free to help. br>I just applied red loctite to the threads and will wait 24 hours for it to cure, but I'd feel better drilling a hole, tapping it, and inserting a set screw, but I really hate to alter the chuck as it is perfect.
" I recently upgraded from a smaller lathe with a 1" x 8tpi drive spindle to a larger lathe with a 1 1/4" x 8tpi drive spindle. br>br>With this tool, I can use my older turning tools and jigs for small to medium-sized turnings. br>br>I've got a bunch of "waste blocks" that I've tapped to 1" x 8tpi. I can keep using them because of this tool. I also have a "Live End" that has a 2 Morse taper on one end and a 1" x 8tpi on the other. I can frequently support my work on both ends with this tool and the adapter. Because I am a novice woodworker, I enjoy doing this. The workpiece does not fly across the room because of the turner and catches.
EXCELLENT U. EXCELLENT U. EXCELLENT Made in the USA! This adapter has excellent tolerances with no "slop. " Steel from the United States that is good and hard. The new chuck threads on and off easily while remaining "snug" enough to prevent slipping. Fits perfectly on a Shopsmith headstock and can be used with a Barracuda 2 chuck (PSI chuck with 1" shaft at 8 TPI). I am extremely satisfied with my purchase and would recommend it to others.
This adapter was purchased to use with a Nova G3 1" threaded chuck (Rockler Item 69733: A standard old Craftsman 12" x 48" lathe with a 3/4" spindle was used to mount the chuck and bowl turning bundle. The chuck runs true and mates well with the lathe spindle. It also snugs up tight against the spindle collar. The solution is simple but effective.
This adapter converts a Shopsmith 5/8" spindle to a standard 1" 8 TPI lathe spindle and is well constructed and finely machined. It was a perfect fit for my Shopsmith Mark 5 (a 1954 model). On the other hand, it was a perfect match for the Teknatool lathe chuck I bought with it. The adapter is beautifully crafted from a solid block of steel.
One of three I bought on Amazon; each supplier had a different set of stock photos, but the part is made by the same company. I came across a website that sells a similar part with pinpoint precision. If you're looking for precision, don't buy this.
This is a large, heavy-duty spindle adapter that has been meticulously machined and polished. Both ends of the screw are smooth and easy to install. It's of excellent quality at a lower cost than what PSI (Penn State Industries) charges. And it's a fraction of the price of other adapters. For more information, take a look at my photos. It rotates true and in the middle. br>br> It doesn't have set screws to secure it to the spindle for reverse operation, but if that becomes necessary, I can drill and tap a couple of holes for set screws. It can't be used with a vacuum chuck because the male threads are solid. br>br>There are two flat spots on the female end for a wrench if needed. A 'Adjustable Slip' is what I use. Lock - The Plumbers Nut Wrench is a low-cost, light-weight tool that can handle the adapter's large size (search Amazon TW408302). Because the adapter is jammed against the chuck and/or spindle, the wrench may be required. The nut wrench can also be purchased from local home improvement stores. This adapter screwed nicely onto my lathe's spindle, right over the spindle's shoulder to mate with the adapter's shoulder, as if it were made specifically for my lathe. I did, however, read a magazine called Q. Someone asked if a stack of large washers could be used to fill in the gap because their adapter didn't screw on far enough to seat onto the shoulder of the spindle. The response was - Because of the differences in hole ID and thickness between washers from the hardware store, it's not a good idea to use them. It was suggested that 'Anti-' be used. To fill in any gaps, use 'Lock Lathe Spindle Washers' (about $2 on Amazon). This may be useful to others, but my lathe had no such problem.

I purchased two of these over the course of a year. Some chucks without a large recess were unable to register against the shoulder due to machining on both. The male threads near the shoulder were not recessed or threaded in any way. To turn it on the lathe and trim this area, I had to make a specially ground tool. This is not something that the user should be required to do!.
