Joe,
I’d recommend the “Scratch Building Basics for Metal Aircraft” DVD from HomebuiltHelp.com. It has some pretty good description on doing this and other things.
I’ve attached a picture of the fluting tools I have. Some are home-made – some are purchased. I also had one I made from rods welded to vise-grips but that broke. The two I finally ended up using was the one with the red jaw (broken and needs to be replaced) and the small one at the top (particularly for nose flutes).

I am having a bit of trouble making the nose ribs on the form block. Using the vise grip fluting tool from Spruce but maybe the 3/8 rod tool shown in the prints would work better. Any helpful hints? |

I can't figure out who posted the question but here is my $.02.
The scratch built video is a very good buy, it will get you going quicker.
The 3/8 in rod ( I use the skinny end of a small ball peen hammer handle) is pounded into the formed flutes on the block. This makes very nice flutes and is pretty easy and quick. I've only used the fluting pliers ( home made ones) for flattening the rib after it is out of the form block.
Hope this helps
Kevin

I wish I would have had that info or thought of that technique while I was forming my ribs, etc. I think I ended up splitting the forming bocks at least twice to apply the flutes with my fluting pliers. It would have made the process go much quicker and easier if I had been able to just leave the ribs in the forming blocks while pounding down the flanges. It all worked out though.
