The_Ed did a marvelous job with my Filco Ergo Clear mod. I can vouch for him. Good luck getting the stems though.
PS - He may ask you to check if the Leopold is RoHS compliant. He was none too happy when it took forever to remove the solder from my Filco.
Thanks for vouching. I guess I should bite the bullet and order 6 more rolls of desoldering braid that will work for RoHS modding. And another soldering tip or so.
Looking to get these 4 modded. As well as a black spacebar
I have a jig for the opposite mod. Center-shaft -> left-shaft. It is at most a few thousands of an inch off. My modded capslock is perfect from every angle with the naked eye. Asperger's Syndrome == Anal Retentive.
