My Latest Slingshot Build

Unread postAuthor: Hrawk » Mon Oct 29, 2012 1:17 am

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
Image

2) Face off each end of the handle
Image

3) Mill out the slot for the fork
Image

4) Chamfer the top of the handle
Image

5) Chamfer the bottom of the handle
Image

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

7) Next hit it with some Kitten Cutting Compound
Image

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
Image

10) Cut the pieces out using the bandsaw
Image

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

12) Mark out for the holes
Image

13) Always centre punch before drilling
Image

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
Image

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

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
Image

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

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

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

21) Sucky part is over, mmmm shiny
Image

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

23) Drill and tap for bolts
Image

24) Check that threads are clean and everything fits together
Image

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

26) Using a rubber mallet bend the fork to shape
Image

27) Put it all together
Image

28) Another MBBS is born :)
