New to the forum
Hi All
I`ve been checking out this forum for a while. I`m a newbie at machining. One year ago I got my first Bridgeport mill. I have spent most of my free time restoring the machine. Now that I`m done and am learning machining I have a lot of questions. Just recently finished making a flycutter and power drawbar. If anyone is interested here`s a link to few pics : http://s391.photobucket.com/albums/oo35 ... CF0008.jpg
By trade I an a self-employed cabinetmaker. I`ve been working wood for 30 years. I have built a few woodworking machines over the years. I do believe I enjoy machine design and construction more then woodworking. At my site I have a few pics of my other machine projects: http://www.woodsolutions.com/diy-cnc.htm
Regards barry

WELCOME
Welcome to chaski golash.
Same here.
I had a fully tooled wood shop where I used to make my own home furnishings.
I thought that because of being a machinist as I retired working with wood would be more fun ... WRONG!!!
Your fly-cutter looks similar to one I made many years ago while working at Jorgensen Steel.
Mine has dual slots for two purposes.
One, better balance thus good a very high speeds.
Two, one can use two cutters at the same time as shown on the pictures.
One bit is some .015" higher than the other. (Staggered cut)

There are no problems, only solutions.

Plans
Hi Willy B
Almost never do I design on paper before I start building. I start by checking out commercial designs. Gives me a feel for design and proportions. I then go to my favorite junk yard. All the time there looking for components that could be used. Its always cheaper to take a existing component then building it from scratch. The design | build is always evolving as I`m looking for parts.
Doing designs in CAD would be time consuming because any changes in parts would require revisions to the drawing. Sometimes I`ll do CAD if I`m concerned how to fit various assemblies together. I guess you could call me a junk yard engineer.

Nice Flycutter
Hi Jose
Nice design on your fly cutter. Always interesting to see other peoples designs.
Thanks for the post with the pics.

One could make a fly-cutter of similar design with three or four slots for bits.
As long as the bits are ground correctly, one cutter with four bits will eat four time the material per revolution.

[old-memory-on] When I was in College, supporting a new family,working in a machine shop, we made a centerless grinder. It was my job to machine the way parts. One was a "V" way cut from ~5" square stock, with the "V" machined on the top, the bottom and sides were stock. Well, that's a lot of material to remove. We had a head for the horizontal mill, and I mounted a WW2 "fly cutter". This thing took 4ea. 1/2" tool bits. I set it up to take about 1/8" deep cut per bit, (1/2" per rev). I tossed blue chips to one corner of the shop, because it was hazardous to be in the line of fire. Removing material from 12' of stock did pile up the chips.

Actually, the boss said that he looked at the neck of job applicants. If they did not have scars, he didn't hire them, since they ran the machines too slow.
I was a kid, too young to know anything, (although I knew it all).
