I made up it as i went along so forgive me for not having any accurate measurements (if any!).
Step 1: Ingredients
10 thou shim steel (a thin steel plate i had two 10"x5" pieces)
nuts and bolts to fix the steel in a ring.
4mm square key steel (or any thin steel bar, the length will depend on the diameter of your windshield, as shown later on)
1mm thick heat resistant mesh (i tested mine by holding a lighter to it for a while and then attacking it with some pliers!)
drill plus 4mm and 7mm drill bits
tin snips or good scissors
needle nose pliers
small flat file (2nd cut preferable)
clamp or strong hands!
pencil or thin marker pen and ruler
Step 2: Cut Shim to Size
file the corners of to remove any sharp edges
i only used two pieces because they were to hand one piece would probably be better.
Step 3: Drill the Shim Ends
Step 4: Joining the Two Shim Plates
join two ends making sure that the nuts are on the outside of the ring when it is fixed together later.
Step 5: Drill the Air Holes
this helps feed the flame without it burning too fiercly.
Step 6: Join the Ring Together
next you need to saw off the extra thread on the bolts and file off the burr.
Step 7: The Grill/pot Stand
cut the key steel to the marked length, lay it over the ring again and mark where the groves need to be cut for the key steel to sit flush in the top as in the third picture.
using the tin snips or scissors cut the vertical lines and the using the needle nose pliers tease the steel backwards and forwards until it snaps off, file off any sharp edges.
once its all cut to size repeat for the second bar.
Step 8: Grill Mesh
i left the 5mm over cut as it helps to fit the bars in and provides stability for the pot.
Step 9: Finished Product!!
hope this is ok for a first time instructable.
update - it worked a treat, cup of tea and naan bread for breaksfast in sherwood forest! it was quite windy but the stove was fine.
