Dennis's Wishbone Frame
Todays post if of a frame i am building for Dennis Y . Had a few start and stop's but we are starting to see some progress now . There is a lot to do before you really begin to see the outline . Just machining up the castings is no one day task. They take me sometimes 2 weeks to put one together from start to finish .
When almost every frame order being slightly different or way different from each other , its like building each one for the first time . It takes a while and who wants me to build one in a hurry ? Would you ? .
Anyways , today was a pretty good day with most of the hard stuff done . Once you know where you want to make your bends and calculate your angles your almost there . Your bottom rails are always the most difficult to produce. There is anywhere from 2 to 6 bends on these rails on most frames ( each side ) . The back bone is a piece of cake . Seat post is 1 bend at the most and straight on some. Rear upper wishbone is another of the easy frame parts .
Need to machine the sidecar loops before bending the Wishbone downtubes . Will work on that tomorrow . Once the downtubes are placed into the Stock Reproduction Neck I make , that will complete the frame from the neck to the rear axleplates we also just happen to MAKE here in the USA .
Dennis has an Accurate Engineering Panhead motor ready to bolt between these rails . Its going to have a moon oil tank with a standard sporty tank sitting on the top rail . I'll be honest and tell you I never get tired of Wishbone frames . There are lots of old cool frames out there and this is one of the last great frames before they went to suspension and screwed up everything. Rigid Only ! Next post will be in a few days of the finished frame along with progress shots to follow the construction .
