Need advice

[MNBenny]

I just realized something. My dad does have a router. What kind of a bit do I need for it? Would I need a special table for it. Harbor Frieght wants only $50 for an electric shears.

Yes, those are Harbor Freight snips. They worked quite well. I built a router table into my bench and used a long trim bit with the rough cut aluminum sandwiched in between. The forum posts referenced above cover everything in great detail. I don't recall if I created a post that talked about how I built the routing forms. I have plenty of pictures on my computer, however.

Do you have Eric Newton's Bearhawk construction manuals? The process of creating the routing forms is identical to what's presented in his books.

Did you buy the electric snips from harbor freight?

[MNBenny]

Hey Chris how did you set that up? Dang wish I had the recent bear tracks. So I need a router for sure. What else do I need

[MNBenny]

I everyone. For some reason I'm not getting them anymore I don't think. Does it describe how to set it up?

My opinion is that Chris' method of making ribs brings together a number of different methods and achieves what I believe is a Best Practice. Keep the bend radius on the flange generous. I set mine to something near the FAA's minimum recommended radius and did not like it.

If you have access to a router, then +1 on S Lathrop 's comment. The article I wrote for this quarter BearTracks will give you some quick insight into the process. For more detailed accounts of my rib-building adventures, take a look at these two posts:

Take a look at this quarters BearTracks. There is a description of cutting the ribs with a router. That is how I did all my ribs. Takes time to make all the patterns but I was able to cut ribs 3 at a time and it took just a few minutes to do each set of three.. Time to a finished rib is way less and a ton easier than snipping them out. Plus they are all exactly the same.

My favorite tin snips are....... The aluminum specific files I use to true an edge......sneaking up to the finish line.

Hi everyone! Happy New Year! Hope your christmas was a good one.

My ribs keep turning out crappy. Does anyone have any ideas that might help me? A BH builder near me has suggested that I not close the snips all the way. I can post photos in case any one wants to see my crappy job.

take care
