Hi Peter, Great project. Your twice weeklies are a high spot. I’ve been lurking for ages while I get my RPL. The reason for this comment is that on inspection of the two cad pics Kyle’s Jig will work for welding the mount — but you wont be able to get it out. The angles of the two slots on the front plate are ‘in’ and the two top tubes are parallel. The font extension wont allow enough rotation. Could be perspective but — better to be safe.
