WM LT15 Side Support Rollers

[kantuckid]

What is the outside diameter of the rollers used for the side supports?

I know they are sold as a kit by WM but I may choose to source them on the open market to update my mill.
 
My mill predates the rollers so I'll need to dril the two most used side supports. 

A template for the bolt clearance hole would help me from having to think :D.

I have seen several related threads here, seems some have used "generic" bearings, etc. of 2" OD w a 3/4" hole.


Thanks!

It's been years ago, but I just cut mine out of some round aluminum stock I had, maybe 1.5 inch? maybe 2"? drilled a hole through them and just ran a bolt, no bearings or nothing.  A little grease every now on them and they worked fine.

Very cheap and effective.

I found sealed bearings on ebay @ under $4 each and most likely I have all the other pieces to make them work in my stash. Looks like a #6304 shielded bearing is the right size.
My mill is stationary under roof so a bearing lasts as long as a roller. I do see why WM would go with a bronze bushing for the overall best choice though, as often out in the weather.
Talk about procrastination-I've been gonna do this for years... ;D

Edit: Rainy today so I did two of my side supports using my Amazon parts stash.
The bearings are 6304-2RS and I bought a ten ea. for $12.99. They also sell 4 each for not much if you only plan to do two supports.
I bought ten each 3 1/2"x 3/4"-10 cap screws for $5.54. Got five left over from my bearing sets that will never get used but price a 3/4" cap screw at a Fastenal or other box stores-if they have them.  Bought ten ea. 3/4-10 nuts for $5.64 and 25ea. 3/4" washers with a 1 1/2" OD, # 7AJ for $7.21. These washers were an Amazon return listed as 1 3/4" OD but in fact were 1.5" as I say. Perfect choice as that played out.  Quite a savings over the WM kits to modify 5 of my supports! WM gets nearly $60 plus shipping for their kits.
On items that matter very little I always search for used stuff like these bolts on Amazon.
Other than a simple removal of one nut on the mill, the other task is to drill one 3/4" hole in your support. An SAE cap screw may require a very slight grinding job above the threads to clear the hole. I say this as most people don't have a 3/4 clearance drill around a home shop.  

Edit #2: Caution! 

Well I (sort of as two were wrongly done) messed up the installation of the 4 bars I now have bearings on. Caught it before I damaged a blade though! When you use a 3/4"x 3 1/2" cap screw as I did, the threads must point toward the ground with the hex head up when the side support is in the down position. If not, the blade will not clear the designed low setting to saw a final 4/4 board near the mills bed and hit the end of the threads.  :
