Path to Up My Sharpening Game

[MetalPro]

I was able to get a FVB unit built during the gloomy weather over the weekend out of spare chunks of metal lying around; got the measurements into TormekCalc and ran through some knives and chisels with the procedure of SG250 against the blade, Sun Tiger 4000 then honing wheel (both from the front, with the blade).  Ran it right off the software values using T USB value and it appears my measurements were reasonably precise and accurate based on the successive scratch patterns. Got 'good' results but it did highlight an issue and maybe the reason for my previous dissatisfaction with honing wheel. It appears the leather on the wheel I have has dried out over the years - particularly along the edges creating a 'U' shape to the surface.  Can the leather on this wheel be reconditioned or replaced?

I feel completely worthless now.
