Glad you are all stocked up. I have plenty of 1/8" and 1/4" thick birch plywood (which is more widely available than the 1/16" thick). I gotta re-up on some 1/16" so I was thinking of passing some savings on to others. Especially if I will be order several sheets or more to have for my builds.
Hi everyone - I am setting up a pre-order to hold 1/16" birch plywood sheets for you. I will have 12" x 61" (5.08 sq ft) sheets available of the real 1/16" thick birch plywood for $18.00 per sheet plus shipping.
I could probably get shipping costs down to $12-15 per sheet. That makes the...
I was thinking of buying the vice attachment in the link below to bend the fin
Didn't mean to turn the tube thread into a turn fin thread, but why not Im sure many can benefit

Very nice and once again informative, I like the idea of learning how to play with metal since I mostly cut wood. I have a solid vice at home and would like to attempt to bend the 7075 aluminum myself. I guess I would have to heat it up first? And I assume i'd hold the fin in a vice while filing
Thanks for the info- I am pretty sure I can cut 7075 aluminum to the overall shape I need with my table saw and band saw (done it safely before), but will probably need someone to roll it for me until I buy a table top roller. I feel filing a knife edge on the turn fin would be a lot of work to...
Thanks for sharing, do you mean "FILED" rather than "filled" I am not sure what you mean by that. Seems like I will need to find a shop who can do the proper bending
Jim- Can you explain how a turn fin is made? Can you wire edm the overall shape, including the "knife" edge and then bend on a certain press? Is the 7075 aluminum strong enough? I need to have a turn fin made and been talking to a few shops and they don't want to do it. I don't have the tools...
I did it similarly on my first rigger I built after speaking with you Jim, but it is difficult to adjust the angles unlike other setups that use shims. Do you or anyone have any ideas on how to be able to adjust the angles slightly with this setup?
