Is there any bad feedback or good on the ONEWAY 2436 or customer service, that someone can tell me.
The upgrade from Powermatic to Oneway is a small upgrade. At this level of lathe it is more about what you become accustom to. The Oneway lathe will work slightly differently and it will take you many many hours to re-train yourself to get the same level of use out of the Oneway as you currently have with the Powermatic. You may find that there are some things you can easily do with the Powermatic can't be done using the Oneway. The Oneway is a 33x5 headstock spindle. That means that you will need to re-insert your chucks and there isn't a market for used inserts (you may be able to give them away).
The Oneway is a terrific lathe. I was a bit disappointed when I first got my 2436. Up until then I had worked on a Record Power CL3. The process of woodturning for me was very interactive. Belt changes, oiling the headstock, aligning the headstock, swiveling the headstock, adjusting the banjo, moving the belt for the desired speed. I was constantly making adjustments to the lathe when turning. So when I spent $$$$ on a 2436 I was disappointed that my interaction with adjusting the lathe was almost non-existent. Turns out that all those dollars make the lathe disappear so that you can focus on turning.
Adding the RF filter, breaking resister, remote on/off are all a pain to install latter on to consider getting these installed when you order the lathe.
The remote on/off is a must have.
If anyone listens to AM radio the RF filter should be included. The powermatic has RF issues so if you haven't had any problems with AM radio using the powermatic you will likely not need the RF filter.
The breaking resister is a two edged sword. If you turn larger pieces then the breaking resister will let you stop the lathe faster. This also means that there will be more "dismounting" force when stopping large pieces. If you use stronghold chucks (or oneway faceplates) with the set screws then you can take advantage of the faster stopping.
3HP is a must because it will insure that your lathe is never underpowered (less reason to change the belt).
Large outboard bed. I have this and get almost zero use out of it. But if 30" and larger pieces are in your future then...
Short bed extension. This is a perfect product for the inboard side of the lathe. The 36" bed (actualy 36" between centers) puts the point of the live center in your elbow when roughing out large bowls. The short bed extension lets you put the tailstock "behind" the control pendent so the point of the live center is out of your way. The tailstock "swinger" could be a solution but was not available when I bought my 2436.
Short bed extension. If you want a short bed lathe mount this on the outboard side of the lathe and it is like sliding the headstock on your powermatic.
Dust hood. I bought one of the first dust hoods from Oneway. I had to upgrade my dust collector but with the dust hood and DC on there is no dust escaping when sanding. That's right, zero dust, even when sanding the outside edge of a 20" platter.
96 position indexing. It is cheap enough and adds 32 and 96 indexing. Even if you never use it the indexing is out of the way.
Stainless steel bed. If you turn a fair amount of green wood, especially oak, this might be a good consideration. Note that stainless is not magnetic and a little softer than the regular steel.
Service with Oneway is terrific. First off you are likely never going to need service. But if you do need service Oneway stands behind their lathes. I damaged the stop button bezel on my remote on/off. The effect was that I couldn't start the lathe, the stop button was being held down. I didn't know what the problem was I only knew that the lathe wouldn't start. So I called Oneway and spoke with Kevin. I was at work and I couldn't see my lathe while talking with Kevin. Kevin took my problem seriously and gave me his home phone number so I could talk with him later that day when I could be at my lathe. He indicated that the most likely cause of the problem was the on or off switch. When I got home I discovered the bur I had raised on the remote off switch bezel when I dropped the box. I cut away the bur and the lathe again worked fine. I e-mailed oneway that the problem had been solved and thanked Kevin for his help.
I have talked to Kevin at AAW symposiums in the past. Oneway has positive woodturning reasons for all design features. For example the hole in the banjo for the tool rest is round opposite the locking lever but oversized on the locking lever side. This is done so that the tool rest is easy to move when the locking lever is loose but rock solid when the locking lever is tightened.
