How to Order and Set Up Oneway Coring System Easy-Core Bowl

The Oneway Coring System is a fantastic way to core out additional bowls inside larger bowl blanks. The process of purchasing the Oneway coring system needs some explanation.

How do I order my Oneway Coring System Easy-Core?

You can not merely do a one-click checkout when purchasing the Oneway Coring System. Instead, you need to make sure you match several components to your lathe and your specific needs.

In this article, I will help you understand the various components of the Oneway Coring System and guide you to the correct parts for your lathe.

After the parts are determined and ordered, I will show you how to set up your Oneway Coring System Easy-Core.

What Is A Wood Bowl Coring System?

When the outside of a medium to large bowl is rough turned, instead of just shaving out the center, additional new bowls extract from that larger bowl blank interior.

From one bowl, two, three, even four or more bowls can emerge. Not only is this amazing, but it also saves wood, produces fewer shavings on the floor and makes multiple bowls from one bowl blank, not to mention it is a thrill to do.

Bowl blanks in the 10-14” range can yield an 8-12” bowl. So a bowl around 8-10” across can be cored to yield another smaller bowl. Larger blanks can produce more bowls.

The process of coring bowl blanks is relatively simple, effective, time-saving, and material-saving.

Oneway Understanding

When I hear the term “oneway” I think of oneway roads and cities I’ve visited that seem to have an excess of oneway roads.

The process of purchasing the Oneway Coring System is much like navigating a city filled with oneway roads. You can turn here but not there, go right but not left.

Even though there can be some confusion when purchasing the Oneway Coring System, I do understand the issue from Oneway’s point of view.

Across the world, there are numerous different types and sizes of lathes. Manufacturing a fantastic coring system that works with most lathes is quite a feat in itself.

Each lathe needs a different base set coring system that is dependent on the lathe swing size. 12-inch swing lathes have a shortcut solution which works well, which we’ll talk about in a minute.

If you have a lathe with a 16- to 26-inch swing, there are a few parts you will need to order specific to your lathe and your needs. Unfortunately, the purchasing process can be a bit unclear at times.

Not to worry, I will help you navigate through the process of getting just the right parts to set up a Oneway Coring System on your lathe.

Three Key Measurements

You need to know three things to get the right parts to assemble your Oneway Easy-Core Coring System.

• The Lathe Swing – distance from the center of the headstock to the bed ways or rails
• The space between the lathe bed ways or rails
• What are the average bowl sizes you are coring

Three Oneway Coring System Components

There are three main components to the Oneway Coring System: the Base Set, the Clamp Block, and the Knife Set.

You need all three components to have a functioning coring system.

The Base Set is the most significant element and as the name implies, the base or hub of the coring system. The Base Set holds the Knife Set and the support armrest for the knife.

Under the Base Set is the Clamp Block that holds the Base Set to the lathe rails or ways.

Knife Sets are inserted into the Base Set as needed to cut a specific diameter core. One Knife Set includes one specifically sized diameter knife and its corresponding support armrest.

The Oneway Base Set

Oneway’s Base Set is the heart of the Oneway Coring System and needs to be sized correctly based on your lathe swing.

The Base Set does not come with any cutting knives, you select the knife sets separately, and we’ll cover that in a bit.

The swing of your lathe, the distance from the center of the headstock to the rails or ways, is used when ordering the Base Set.

For example, a lathe headstock to ways distance of 8” between equals a 16” swing, a 10” distance equals a 20” swing, and a 12” distance equals a 24” swing.

There are Base Sets for lathes with 16”, 20” and 24” swings. If you are turning on a 12” swing lathe, there is a shortcut kit.

12-Inch Swing Shortcut

If you are turning wooden bowls on a 12” lathe, Oneway makes a specific Oneway 3270 Easy-Core 12″ Mini Coring System just for 12” lathes.

This kit includes the Base Set and one Knife Set. You only need a Block Clamp specific for your lathe to complete this 12” coring set. We’ll talk about that in the next section.

Because the 12” lathe has a smaller area for turning bowls, only one Knife Set is available for this size lathe, and it is part of the 12” Mini Coring System.

Even though only one knife is available, you can still make two bowls out of one bowl blank, and that is a double big deal.

The Oneway Block Clamp

The Base Set needs to be anchored and held in place with a Block Clamp, and the Base Clamp fits snuggly between the bed rails.

Because manufacturers have different distances between the bed rails or ways, you need to make sure you get the right Block Clamp for your lathe.

Measure the distance between your rails and order the Block Clamp that matches that distance.

Measure the distance or gap between the bed ways or rails.

1-1/2″ space between rails, purchase Oneway Clamp Block 1-1/2″ Gap
1-7/8″ space between rails, purchase Oneway Clamp Block 1-7/8″ Gap
2-1/2″ space between rails, purchase Oneway Clamp Block 2-1/2″ Gap

*At this point the Oneway Easy-Core 12″ Mini Coring System is complete, no other items are needed other than a sharpening jig to sharpen the blade, and perhaps an extra spare cutting tip.

Oneway Knife Sets

Each Knife Set includes a cutting knife with Cutter tip and a correspondingly sized support armrest.

Take a moment and determine what size bowls you typical make or potentially want to make. The size or sizes of the bowls you make determines which Knife Sets you need.

Also, the Knife Sets can be added later as you go as well. You only need one Knife Set to begin coring.

The size in the name of each Knife Set indicates the final bowl diameter that Knife Set cut. So a 9” Knife Set has a 4.5” swing, the 11.5” Knife Set has a 5.75” swing, the 13” Knife Set has a 6.5” swing, and the 16” Knife Set has an 8” swing.

If you make a lot of 10-12” wood bowls, the 9” Knife Set may be all you need at this point.

On the other hand, if you like making large bowls measuring 18” or larger, you might want to purchase all four Knife Sets.

I use the 9” and the 11.5” Knife Sets for most of my wood bowl blank coring needs. On average my largest bowl blanks are around 14” to 15” in diameter.

Easy-Core Cutter Sharpening Jig

One last item to include with your set is the Easy-Core Cutter Sharpening Jig.

I did not order this simple little device initially, and my Cutter tips suffered a bit because of that. I recommend using the sharpening jig to get clean, crisp, sharp edges every time.

Once you are through with this article, be sure to read this article all about how to sharpen the Oneway Easy-Core Cutter tip.

Cutter Tip

• Oneway Cutter Sharpening Jig
• Replacement Cutter Tip

I recommend purchasing an extra Cutter tip.

Over time, the Cutter wears down and needs replacement.

Also, there is a risk of dropping the Cutter tip when it is removed from the Knife Set.

It helps to use a magnetic tray to hold the Cutter and the holding screw when you are sharpening. However, I like to have an extra Cutter tip on hand just in case.

Setting Up the Oneway Coring System Easy-Core

Well, you’ve done it, you’ve navigated the sizing and purchasing process, and you have your new Oneway Easy-Core Coring System. Now it’s time to set it up.

How do I set up the Oneway Coring Easy-Core System?

Here are the steps for setting up the Oneway Coring Easy-Core
System:

• Use the supplied bolts to fasten the knife and rest holder posts in place on the Base Set.
• Be sure the Knife post pointed base faces outward towards the headstock.
• Remove the banjo from the lathe, or remove the tool rest and slide the banjo against the headstock out of the way.
• Set the Base Set on the lathe rails.
• Position the Block Clamp under the lathe rails so that it fits snug in between the two rails.
• Take the Block Clamp bolt and run it through the clamp and start the threads into the Base Set.
• Snug the Block Clamp bolt but don’t tighten it yet.

• Find the center point of the headstock and adjust each Knife Set to precisely the center point of the headstock, by using the set screw and nut at the bottom of the Knife Set.
• Adjust each Knife Set support armrest to fit snuggly up under the cutting knife leaving no gap or space.
• The Knife Set handle can be attached to the swinging cutting arm of the Knife Set using a hex wrench.

Note – be sure the support post base cylinders stay clear of debris and shavings as that can affect the height of the Knife Set.

Now, the Oneway Coring Easy-Core System is all set up and ready for use.

Centering the Oneway Coring System

The most important part of this set up is to have the top edge of the Cutter tip at precisely the center cutting line of your lathe.

Before setting up your coring system, turn a bowl blank and position the solid bowl center facing outward.

With the lathe running, make a light pencil tick at the very center point of the bowl blank. This mark is the center line of the lathe, and you want to hit it perfectly when adjusting the Knife Sets height.

If you have a 26” lathe, which I’ve yet to see one in person, you can purchase the 24” Base Set and extend the set screw downward on the Knife Set to center the knife cutter as you need.

I will be posting a detailed article soon about how to use the Oneway Coring Easy-Core System. That article will include all the details for how to operate this system and how to precisely size and core out each bowl.

Oneway Coring System Set-Up Conclusion

The Oneway Coring Easy-Core System is a bit tricky to understand at first because of the multiple parts needed. However, once you’ve sized and ordered your specific elements, the whole system takes shape and becomes much clearer.

I hope this article has helped you see how to size and purchase your Oneway coring system.
