For those of you who have been at it for awhile, you may already have lots of cup turning accessories that are based on the square rod system. This conversion kit allows you to use the SpinIt with all of your Rotisserie rod based accessories! You'll also get a few other added benefits with this kit!
The SpinIt supports all of it's weight on the motor directly and as you can purchase it, only supports a few cups. Our aim is to allow it to support ALL cups and give it's motor a longer life by taking some stress off with an idler arm.
This kit comes with parts modeled specifically around the shape of the SpinIt, and tested for a tight tollerence fit! The kit includes new back feet mounts, front feet mounts, an idler arm, square rod clamp, and 5/16 to square rod adaptor.
Lets go over some design features:
- Back feet:
- The back feet have been modeled around the SpinIt base and fit around the factory injection molding lines to add support. To allow the least parts, it's printed as a single piece that stretches over the top and hooks on.
- With screw holes as well as a flat bottom, it can be secured with either screws or double sided tape.
- Modeled to the same height as the front feet to keep your cups level!
- Front Feet:
- Allows the same mounting style as the rear feet for a secure connection to any surface.
- Slots over factory design elements and secures to our idler arm for a very solid, from factory feeling!
- Idler Arm:
- Keeps your rod perfectly level, no sag introduced with heavy cups/tumblers from the single motor mount or stock wire insert
- Extend the life of your motor by taking stress off of the motor shaft
- Adjustable Cup Inserts:
- Adjustable size cup inserts mean you won't need to use a foam football or the stock wire insert anymore! You can adjust the size and print to fit almost any cup you have!
Non printed hardware:
M3 x15 socket head screw: 2
M3 x12 button head screw: 2
M3 Hexnut: 4
Double sided tape or Wood screws
Optional: White Lithium Grease or similar
After printing all your parts(follow printing instructions below), you'll want to get things put together! First you'll put on the rear feet. Turn over your SpinIt and take a look at the underside of the turner. The model has a plus shape in the top that will slot over the plus shape directly under the turner motor. Match the small square side of the plus to the side next to the nubs that protrude. Carefully align the piece, hold around the screw holes with index fingers while your thumbs are in the middle of the foot. Bend the part slightly so it will fit over the edges of the SpinIt base. Careful not to bend too much as you can crack the part(depending on what plastic you printed in). You can also slightly warm up the part if you're worried about cracking. It'll satisfyingly slide over and pull back into shape.
The front feet will just slide into the bottom of the base. It's tight fit so if you printed it well you may get a little 'click' when it pops into place.
The front arm will need non-printed part assembly before being added. On the inside of the legs you'll see two small rectangle holes. These are for your M3 hexnuts. You'll want to be sure to insert your hexnut making sure the flat sides match the flat sides of the rectangle hole. Use a small screwdriver to push them in so they align with the screw hole in the model. You can test with a screw if you're not sure.
Once you have the hexnuts inserted, put the arm on top of the front feet, as seen in the assembled pictures. Use one of your M3x15 screws to go through the bottom hole and into the arm where you just installed the hexnuts. Repeat on the other side/hole. Tighten so that there is a secure bond between the SpinIt, front feet and idler arm. You can insert hexnuts into the rodclamp at this time as well in the same fasion. insert your M3x12 screws so they hold the nut in place but don't protrude into the square rod slot.
Now you can screw in the 5/16th to square rod adaptor into the SpinIt, be careful not to crossthread on the first time you screw it in. It'll be a snug fit and bottom out once you've screwed it in all the way.
Do a test fit with square rod and find the length you'd like your rod to be, we used a 12" cut in the pictures above. Once you've got the length, cut your suqare rod. With the length cut, insert it through the idler hole, and slide the rod clamp over the suare rod, with the round nub facing the idler arm. Slide the square rod into the adaptor and move the rod clamp up to the idler arm so that the nub is in the idler arm but not pushing too hard against it, it should 'idle' with no forward or backward force. Tighten the rod clamp M3 screws and ensure the clamp doesn't move.
Optional grease: Since this is plastic on plastic there can be a squeak between the idler arm and the rod clamp. Since this only turns 8RPM max it's not going to hurt anything but it can be annoying. You can apply a bit of grease on the nub so that it does not squeek. I use white lithium grease or Super Lube.
You're all done with your conversion setup!
By changing where the cup sits we are changing the center of gravity and need to secure the SpinIt before use! Use the Double sided tape or wood screws to secure the SpinIt where you'll be using it.
