Phil,
Congrats on your new BX!
I mounted three upright pieces of pipe on my drawbar and stacked barbell weights on them. The pieces of pipe are locked onto the drawbar with set collars. I then slid one end of my adjustable top link onto the top of the middle piece of pipe to stabilize the rig. I bought my used plastic coated barbell weights at a local St Vincent DePaul store(like Goodwill). They were very cheap. Earlier I tried hooking a heavy lead weight onto the 3 pt,it worked, however it was difficult to get off and on and it was very tough on my back. Barbell weights are much easier to take on and off. I have been using this set up with my front blower this winter and will probably use it with my FEL in the spring.....
