first
let's sand a spot near the butt and the end of the butt so we can see the grain and try to find what wood is in the butt. i convert a lot of these and you atre amzaed at what you might find under all that dirt and grime. as with many old bar sticks the butt is going to have a oversize diameter butt and will need to be recut.
if the cue is near straight and is at least .85 - .87 diameter at 29 inches from the butt it can be converted, but most of the time you will need to replace the shaft as most are too small.
i had a guy send me an old crappy looking titlist to see if we could save it for conversion, we were both shocked after the first recut the wood was a beautiful curly purpleheart.
cross your fingers and give it a sand
