    • Great Adaption for ShopSmith Lathe Chuck
Size: Shopsmith 5/8" to 1" x 8tpi
Great adaption for my ShopSmith lathe chuck. It attaches and removes easily and is very sturdy. I wouldn't be able to use the Nova Chuck without it. Highly recommend this attachment

    • Extra heafty, extremely sturdy!
Size: 3/4" x 10tpi to 1" x 8tpi
I bought this used, and I received what looked like a brand new part! The adapter is a heavy beast and sturdy, so it's very stable. Description is accurate. In cause anyone was wondering, The bore inside the adapter does not go all the way through and the opening is on the skinny side. The thicker side lines up perfectly with my wood lathe chuck and once on there, it's really hard to get off unless you put on some kind of anti thread lock (works out for me). ... show more

The above picture of this adapter doesn't do it justice. I was surprised at the quality. This item is a large, heavy weight, finely machined and polished spindle adapter. Both ends screws on smooth. It's top quality at a price that's cheaper than PSI (Penn State Industries), sales it for. And a lot cheaper than other adapters are sold for. View my photos for more detail. It turns true and on center. It doesn't have set screws to lock it to the spindle for reverse operation, but I can drill and tap a couple of holes for set screws if it becomes necessary. It has a solid core on the male threads so you can't use a vacuum chuck. On the female end there are two flat spots for a wrench if necessary. I use an 'Adjustable Slip & Lock - Plumbers Nut Wrench,' its cheap light weight and can accommodate the large size of the adapter (search Amazon # TW408302). The adapter does jamb tight against the chuck and/or spindle so the wrench might come in handy. The nut wrench is also sold at local home improvement centers. This adapter screwed nicely onto my lathe's spindle, right over the shoulder of the spindle to mate with the shoulder of the adapter, as if it was made specifically for my lathe. I did read a magazine Q & A article where someone said their adapter didn't screw on far enough to seat onto the shoulder of the spindle and was asking if he could use a stack of large washers to fill in the gap. The answer was - not a good idea to use washers from the hardware store due to variation in hole ID and thickness from one washer to another. It was suggested to use 'Anti-Lock Lathe Spindle Washers' to fill in any gaps (search Amazon, about $2). Maybe this might help others, but it was not an issue with my lathe. Specs: OD at female end: 2 1/16" Depth of female pocket: 1 1/2" Depth of shoulder inside female pocket: 1/4" Length of male threaded end: 1" Total length: 2 3/4" Wrench size to fit flats: 1 13/16" Weight: 1 lb. 4.8 oz.

Needed an adapter to convert my lathe to a 1" x 8tpi spindle. Works perfectly and made my lathe more versatile.

Size: Shopsmith 5/8" to 1" x 8tpi
This looks well machined but with a bad issue. I bought this for a Shopsmith V but it is entirely too tight to install on the spindle. I used a round file to try to remove a slight amount of material to limited success, but I still could only get it connected about a quarter inch, not enough to engage the setscrew. Oiling it and working it back and forth for a while it seems to be slowly working it's way on, but still only halfway but enough to secure it. I had to hammer it off the first time just to get it off the machine. I'll keep working on it until I find a better option. Edit: I ended up turning on the headstock with no attachments and ran fine sandpaper over the spindle to remove a thin layer of material or possible built up oxidation. The part fits on properly now, between both actions I took. I would have rather not done it but the removal was so minimal that it won't affect much. ... show more
