Here's some slingshot porn for all of you who like build along threads.

This is me making another MBBS with Aluminium Handle.

If anyone has any questions regarding any of the steps you see here, please feel free to ask.

1) Cut stock to length using band saw


2) Face off each end of the handle


3) Mill out the slot for the fork


4) Chamfer the top of the handle


5) Chamfer the bottom of the handle


6) Start cleaning up the handle ready for polish. Starting with 240 grit and working up to 1200


7) Next hit it with some Kitten Cutting Compound


8) Finish up with a 2 stage polish on the buffer. Tripoly compound followed by SSX

9) Getting started on the forks. Mark out the blank stock ready for cutting


10) Cut the pieces out using the bandsaw


11) Clean and square up the ends on the disc sander


12) Mark out for the holes


13) Always centre punch before drilling


14) Drill the holes. Using a drill press can be fiddly on small pieces, so I just clamped them up in the vice and used a hand drill


15) Holes are drilled and burrs are cleaned up on the belt sander


16) Align the clamps to the main fork arm and drill holes

17) Mark out and punch the centre holes in the main fork arm


18) Drill holes and tidy up with another lick on the belt sander


19) Bolt them together and round out the corners as well as sanding the ends flush


20) Now the sucky part begins, hand sanding and polishing. Boy do those small bits get hot on the buffer


21) Sucky part is over, mmmm shiny


22) Clamp up the handle and insert the main fork arm, mark holes


23) Drill and tap for bolts

24) Check that threads are clean and everything fits together


25) Setup up fork arm in vice, square it up ready for bending


26) Using a rubber mallet bend the fork to shape


27) Put it all together


28) Another MBBS is born

Shineh!!!! Kudos, and nice of you to document the build too

You could fit a high pressure coaxial pneumatic launcher in that handle y'know

I wish I had a workshop like yours
Nice polishing

Looks really good
