Power Drawbar For Rf-30?

The Belleville washers I used are 12.2 mm ID, 25 mm OD, 2910 newtons,(654 lbs)

Made by Associated Spring Raymond, BD025-150

I bought package of 10 for about 13.00 usd last year from Amazon, seems as if they have raised the price to about 30.00 usd now.
 
The spring I used on the quill depth stop wasn't quite right for the job. It turns out that 4 rubber garden hose washers are perfect to keep the drawbar from hitting the crosspiece, but are easily compressed when needed to release the tool holder.

Thanks for the feedback Ben. My little mill/drill which is mainly used for drilling as I have a bigger mill is going the get a upgrade. I will be doing a quick change setup like your's, I have ordered 3 digital scale similar to your's and a gas spring to help take up the play with the down spindle
 
I've got a captive drawbar on my RF 25, and use a ryobi cordless impact drill. It ejects the MT3 collets and tooling I use no problem at all.

I followed the same format as explained by cuppa joe, here:

 
I considered the captive drawbar, looks like a good idea, but chose to go with the Belleville washers instead.

The RF30 has a 1/2" hole in the spindle, and the drawbar is 7/16" dia. You would need to bore the spindle 17/32" an inch or so deep. I don't have a drill bit that size, and when I envisioned myself standing on a stepstool trying to drill it by hand, and then tapping 5/8-11,( not gonna remove the quill and mount in the lathe to do properly) I quickly lost interest in that idea. Would also have to turn down part of the drawbar to 3/8" to fit through the bushing.

I wound up having to make a whole new drawbar anyway, so maybe it wouldn't have been so bad after all....

I have my mill mounted a bit higher than usual to save my back, so when the head is in the higher position it is a good stretch to reach the drawbar, so I wanted to avoid having to unscrew it altogether.

BTW, nice job on the "Cuppa Joe" mod, I have a 20 mm shaft and linear bearings waiting to do that to mine eventually.
