pipe cutting guide question
 

I think I have seen this before but can't find anything in the search of this site or the internet. It was a sliding pin pipe cutting guide that aided in marking complex cuts on pipe i.e. rollbars. It slid over the pipe then you butted it up and the pins formed the outline of the cut needed. If anyone has a lead on where this tool is it would appreciated. I can't believe I can't find a dang thing. I must be using the wrong search terms. I have tried saddle guide, pipe cutting guide, pipe alignment, just about every combination available.

Longacre sells them under their name too. They have a set in stock at Dave Turner Motorsports in San Diego. I really don't know how usefull they'll be though, you'll still have to do some fine tuning with a grinder.
