Hopefully Im posting in the correct section. Im not a sheet metal expert & this is my first RFQ here so please bear with me.
1) Material type
Im checking on this now, but Im suggest either 2024 or 7075 based on higher tensile strength vs 6061. ie its important that the shape is maintained under repeated landing loads (4.5# model). If you have some experience or recs in this regard, Im happy to here them. Material thickness = 0.080", I got that nominal (gauge thickness?) dimension from link below & it compares to a comparable gear I have on hand.

2) Is a material quote required or is material supplied.
Material to be supplied by fabricator.
3) RFQ Quantity = 50
4) Drawings should be immediately available or necessary specs.
- can email provide Rhino v4 cad file (cant seem to upload here today)
- I (attempted to) unfold the 3D bent surface into its 2D-plane pattern if that helps with cutting pattern & estimate.
- I assumed 0.100" bend radius but not sure if this is reasonable with material type, thickness, angle etc (the radius isnt critical, just getting the angles matched correctly)
- suggested tolerance on the pattern dimensions +/- 0.020" (hopefully this is reasonable without adding undue $).
5) Required time frame
about a month, negotiable to your timeframe
6) RFQ ending time = Aug-15-2008
7) Contact information
email petertha@shaw.ca
9) Make known any special treatments/finishes not necessarily related to the machining process.
- no surface treatment required at this point, however, depending on price I would like to investigate cost of top/bot equal corner rounding (bull-nosing) all edges & possibly color annodizing.
- of note, I have other similar parts in consideration, so seeking manufacturing relationship for some ongoing rc model work hopefully
