I wanted what is refered to as a "float" mount, which has the gear leg socket for both the front mains on a tail dragger and the nose gear on a trike. This is to allow me to change my gear configuration from a tail to a nose dragger or put it on floats. Van's had previously supplied a few of these to a few customers, but were also happy to just giv= e me the phone number of the guy that builds the mounts for them. Once I talked to this guy I explained that I was using it for a rotary and that I needed to design my own engine mount but wanted the gear portion of it. He was happy to build me a partial mount that consists of all gear legs and th= e firewall mount. He also supplied all the tubing that I required to finish the mount. He built the mount and shipped it to Van's along with another batch then they put that in my finish kit, so I didn't even have to pay any extra for shipping. It wasn't powder coated and the gear legs weren't reame= d to the final dimensions. I was very pleased with the whole thing and building the rest of the mount was another rewarding experience. I don't have the guy's name or contact info right now, but I'm certain that it can be found in the archives as I know I've given this info before. Search back at least 7 years and you should find it.

Bryan, if you decided to drill your legs, in addition to a drill press, the drill bit itself is important.=A0 I would not attempt it unless I used a quality colbalt drill bit (not carbide -=A0too brittle).=A0 I would start off with a drill bit undersize but not smaller than 1/8" perhaps 3/16" (too small and they may wander).=A0 Then if you progressively enlarge the hold with a larger drill bit, you are more likely to drill a straight hole.=A0 You will need to dril= l at a slow rpm or risk burning the drill bit and hardening the metal even mo= re.
