Larry, i used 7x14x2mm stainless steel washers.
I flexed it to the right size so that fits perfect into the bearing holder.
I measured the holders inside and made my "special washer" so that fits perfect without bending.
Like you can see on the first pic you can "see" , if you can imagine, a lot of space between the tube and holder.
With my mod there is no space between them.
There is no chance in hell to punch a bearing through the bearing holder again
