Yamaha R1 Tail Bracket Set

Personal race program // Sheet Metal Design, Fabrication & Club Race Packaging
The Challenge

A Moto Holders race subframe saves weight, but it shows up bare. The Carbonin tail, seat bracket, rectifier and ECU all still needed a solid home that comes apart fast in the pits.

What I Did

Modeled the frame area and bodywork interfaces in Autodesk Inventor, made drawings and DXF flat patterns, test fit printed versions where it was tight, then cut, formed and installed the parts on the bike.

MT-10 Peg Extension Bracket, Redesigned for Metal AM

Client: motorcycle riding school // Design for Metal AM & Topology Optimization
The Challenge

Passenger peg extension brackets for a riding school's Yamaha MT-10 fleet. After the CNC quote, they asked what the part would look like designed for 3D printed metal.

What I Did

Kept the bolt pattern and mating faces, ran topology optimization on three load cases, checked FEA every iteration, then turned the result into a clean NURBS solid with the holes, taps and machining stock in Inventor.

Started asPocketed 6061-T6 billet
MassAbout 190 g to about 134 g

Ducati Panigale V4 Brake Cooling Cowl

Personal race program // Aerodynamic Ducting & Design for Printing
The Challenge

Get air onto the front caliper with nothing but the existing mount bolts to hang the part from, and stay clear of the rotor, the fork foot and the fender.

What I Did

Modeled in Autodesk Inventor as an assembly with the 330mm rotor and the caliper mount in place. A scoop beside the axle feeds a curved duct to the caliper, and the ears clamp between the fork lugs and the caliper. The left part was printed with a mirrored right and test fit on the bike.

Modular TIG Torch Handle, Prototype P1

Kind of a Big Dill product
The Challenge

One handle design for both WP-17 and WP-26 TIG torches, sized for a gloved hand, with a way for air to move through the grip.

KBD Engineering Solution

Two parts: a core that slides onto the torch and a diamond-knurl sleeve that threads onto it. Grooves in the core close into 16 air ducts under the sleeve. A stem gauge and thread coupons print first to prove the fit.

Deliverables
  • ✓Core and grip sleeve for both torch sizes (150 / WP-17 and 250 / WP-26)
  • ✓Fit-check coupons: stem gauge, core thread and sleeve thread
  • ✓Print pack: build plates, individual STLs and STEP files

XR50 Chain Guard, Rebuilt From the Loads Up

Own project: 2001 Honda XR50 pit bike
The Challenge

A printed heel guard that keeps a boot off the chain snapped at the arm and cracked at the bolt holes under a 180 to 220 lb rider.

KBD Engineering Solution

Root cause review, then real load cases (225 lbf heel push, 180 lbf on the edge, scrub both ways and chain slap), keep-outs for the chain, bolts and frame, and topology optimization with FEA on every version. The final part bridges both bolts, uses an open skeleton pad and keeps the mounting face clean.

Deliverables
  • ✓Failure review and root cause
  • ✓Load cases and keep-outs from real riding
  • ✓Topology optimized, smoothed design with STEP for Inventor
  • ✓FEA comparison against the original part
Pad movement3 to 8x less (simulated)
Worst case0.225 in to 0.028 in

Drone Base Plate, Lightened With FEA and Topology Optimization

Client project (name withheld)
The Challenge

Replace a three-piece multirotor lower frame with one carbon fiber plate, as light as it can be without going soft, with every mounting hole kept.

KBD Engineering Solution

Built load cases from how it flies (motor thrust, roll twist, battery inertia), ran SIMP topology optimization across all three, and checked every revision in an orthotropic plate FE model validated against hand calcs. Then designed a ribbed printed CF nylon version to compete with it.

Deliverables
  • ✓Four plate revisions with STEP, DXF and a one-page load check each
  • ✓Validated plate FE model and a 3D voxel model for the printed version
  • ✓Weave orientation finding for the cutter
  • ✓Printed alternative with print orientation and material notes
