Jack Frosty

My new Chicago winter ride! and that means ready for ANYTHING the sky,lake and planitary orbit/axial tilt can muster.

The first drawing is of the overall design. You will notice a Paragon machine works sliding drop at the rear of the SS/CS's. this was an excersize in machining but really not useable. Reason is that there is no reason to use unless I plan to run rear disk brakes... and for this one.. no. Gonna be fixed with a really low gear ratio.. something like 32/18 front/rear cog. The second image is the fillet braze forward drop I designed for the task.

The slider design+ crown weighs in at 15 oz.. almost a pound. I also plan to use a SON28 disk brake friendly dyno hub= 1.5 lbs. all by itself.

Sooo, thats 2.5lbs of frame weight before I even grab a tube for the front triangle. The front tri will be of .028" wall strait gauge Cro Mo hand bent by my buddy Steve. The rear triangle is of deda 's' bend cs's and telescopic .625"/.5" strait gauge tube in wishbone shape.

About incorperating the SON28 hub.. the fork blades nest in a custom crown cut by yours truly.. see previous posts....

25.4mm x .9/1.3mm round blades. strait to hub. running a front and rear light powered off the dyno. Both have capacitor powered stand light power.

New Rocket cycle works owner.. He is providing the fork..

binder slot... and DONE!

Off for paint now.. to Spectrum for Ducati red love. Gonna be sweet!

Sorry for delay

here is the last... Frame prepped today. Tip***

chase the shell BEFORE paint. If the tool binds and racks the threads.. silver can be added to repair.. Not that I have ever had this problem.. but just saves a paint job if something goes wrong. Also fit the chain stays in the shell ( if using lugs) so that there is minimal material protruding into the shell. This makes for a smooth tap cutting job to full depth. Otherwise the excess material will need to be removed so that the lead in of the taps will clear. DO NOT USE A GRINDING STONE!!! do the job with a file. Fragments of the grinding stone might embed into the steel. this will reak havok on any tap feed into the shell... HSS is fragile and if it sees ANY sort of stone fragments.. the tap will fracture and dull..

The best practice is to build it tight and not have to remove marterial!

tips

crimp

Made a crimping die to form the drive side CS for gear cluster clearance. Using forward facing tips... first step away from single speed! Need to dial in the male insert to create a form that is pleasing and works. Six tons of pressure later... This effort works and will be encorperated.. just need to fine tune... al things in good time!

Cheers,

mock up

today was prepping the ST sleeve to match whats going on with the rest. That and some lug finishing... lotsa file work Yo!! Then to loose fit the sub-assemblies together to make sure what I have in my brain matches the work that is going on with reality. All cool so far! Just a little of this and that to fine tune curve and 'linewise' so it all plays nice!

sub-assemblies

with some atmo mixed in!! shore lines are good but the wash bothers me. Time and time again working will refine. The fork sockets are half done.. ran outa steam for this day.. now I just gotta match.

First try at lug work.. Just shaping and thinning little bit
