What's perverse about it Justin? The information would be useless to anyone who doesn't know how splines are normally cut, but probably somewhat useful to more than a few of our Asian friends who monitor this board regularly.
Putting on my "Don hat" now, and telling it like it is with no regard to who I may offend, one of the problems on this board, and most others, is failure to read EXACTLY what was asked, combined with questions that don't ask what the poster really wants to know. Case in point...."interested in making custom aluminum shift leverS". Note the plural form of lever, implying the person wants to make multiples of the product. Now, go back and read every post in this thread and tell me exactly how many replies have the remotest applicability to production parts. As the thread progresses, it becomes obvious the poster wasn't interested in how do this on a production basis anyway. What he wants is the $1.98 solution, so the posts that would appear to not address the original question, do in fact address the real question he was asking. If he had clearly stated what information he was really looking for, I wouldn't have wasted time posting anything at all. What I did post was the most direct response so far to the question he asked. Specifically, the 2 most common types of tooling used for low to medium volume spline broaching, along with fairly current cost estimates for each type tooling in the size range needed.
Unfortunately, I don't have a compendium of politically correct responses to use when I give a direct and correct response to a question and get some smart-assed remark in return. So, lacking these social skills, I find it simpler to just take whatever insult they want to spout off, raise it to about the 5th power, and send it right back to them. If you can't take it, then its best to not pass it out in the first place.
