Motorized Drift Trike

IV2014 format. Build only files. First "stable" version: https://www.dropbox.com/s/6ih1gwa9gwaiyyt/DriftTest2.mp4?dl=0. Sharing my building journey as there's limited info available, thanks to Ben Burgstra's GX200 model (https://grabcad.com/library/honda-gx200). This isn't version 1.0, but it shows current progress with updates and refinements planned. Not for rendering use; these files were utilized for garage geometry and CNC router jigs. Sketches on TUBE1.ipt reveal basic skeleton and jig components. Started with a Huffy Slider kit from Walmart, used frame and cut off back end. Initially planned bolt-on rear end but dismissed it post-assembly. Conduit bender was used to bend rear frame pieces out of 3/4 rigid conduit, welded with Mr. Crappy wire feed welder. Pipe notching assistance from a site similar to http://www.blocklayer.com/pipe-notching.aspx. Kart parts comprised the rear end; used narrow wheels and pillow bearings (available on eBay, USA Bearing, etc.). NEXT bike fork and wheel converted to threadless setup with Huffy bars and headset. U-style brakes were ineffective, and bike was back heavy. Clutch engagement lower than idle, so governor was disconnected (limited revs via throttle linkage bracket) for improved performance. Sprocket size experimentation led to a 72 (~10" diameter), making the ride less erratic. Huffy plastic seat replaced with one from this image: http://images.johndeeregifts.com/images/products_jd/en_us/detail/AM133476_LGDT.jpg, requiring seat adapter plates. Front end issues involved useless brakes and bent wheel; solution was Mongoose Massif front wheel and fork purchase ($120). Shimano disc brake upgrade planned. Highway pegs welded, but recommendation is to remove and weld off frame for easier process. Tried Shimano hydraulic brake setup (effective but overkill), largest 209mm disc sufficient. Color change implemented; updated pics added. Pegs failed due to fatigue; professional TIG welder repairing and adding web and gusset reinforcement. Pipe tire mounting method improved: apply 3M Super 77 on inside of pipe, clean rubber tire with gas, spray rubber tire with 77, inflate to 35-40 PSI before joining pipes. HDPE pipes to be tested soon. Frame fixed and shored up highway pegs; updated models in pictures.
