Hope 45D doesn't read this post or you may come under attack!
"Under attack?" Seriously?
First off, Mike is not the only one that offers correction of short arbors. Jackrabbit, Outlaw Kid and several others offer services of this nature and have been quick to affirm the problem does exist. If your Uberti does in fact not have a short arbor condition, consider yourself one in a million and never sell that gun, as it's rare as a double-stamped coin and probably as valuable.
Second, Mike hasn't attacked anyone I know of, he just stands firmly behind his knowledge and expertise on the matter. Neither is he creating a 'false scenario' to dupe people into sending him their 'imaginary problem' for correction; far contrary to that, he has offered (on at least 4 other forums I know of besides this one) a crystal-clear description of the issue, both in text and actual detailed photos, a very concise description of how to identify the condition, and most importantly, he goes out on a limb to assist people in making their own corrections of said problem, rather than the usual "send me your gun and your money and I'll fix it". Mike has done three of my open top revolvers to date, ALL had short arbors (none were Ubertis) and ALL are the finest action guns in my collection. Hands-down.
Please don't take this as an attack on you; if you have the ultra-rare Uberti with the correct length arbor I'm truly happy for you. I'm just confirming that the problem is real, and that all my open tops (including the 3 Mike worked on) have this issue, Uberti included, but also numerous other makes. The problem is real; the fix is easy and cheap, and thanks to guys like Mike, the "how to" is available for anyone who wishes to address the issue.
