Let's see if there's any machinists in the house.
I'm building a new steering system for my Baron. I would like it to consist of a Terracycles Flex-Stem, flipped backwards, and a RANS LWB riser. I will add a stop to the Flex-Stem, so that's not an issue yet. The problem is the RANS riser.
The riser is listed in Hostelshoppe as 1 1/8" OD, 1" ID. If that were true, it would fit right over the 1" extension of the Flex-Stem. It does not. The 1" figure is merely a nominal number, and actually measures 15/16", so if I want to use it I need to remove some material along the inside diameter, for about 3" into the riser. Any ideas on how I would do that? Using emery cloth sounds like way too much work and not very accurate either. I've got access to common hand power tools and a drill press, but no fancy shop equipment.
