Grizzley Fly Cutter - What A Fun Day + Tutorial Site

[countryguy]

So much posted everywhere but I will add a quick note to the pile. I did not see a write up above for flycutting. But It may be around.

Bought the 20$ something grizzly flycutter and then watched the videos on how to craft the hard steel cutter stock it comes with. Mine were noted as H2 and on grinding made a dark red and short spark squirt. Seemed to be really good steel folks.

My son and I took most of the day today making several rake angles and speed and feed tests on mild steel. We had some really cool chips coming off.

Here is the site we used. He has a very detailed youtube vid on making the cutter and cutting aluminum and steel. The feeds and speed are much different tween the two.

I remember making them as projects in vokie , first year in machine shop. Still have and used them over the last 40 years. We had lessons on grinding tools for every kind of job surprising how many ways a tool bit can be ground and many different machines use them. Let alone the different fly cutters you can make and use.

I have one of those sets, do yourself a favor and replace the set screws with better ones before you get a tool bit permanently stuck in it.

The setscrews in mine seem ok but the allen wrench that came with it is made out of cheese.

My set didn't even come with wrenches.

I'm asumming you got Item# H7537. I ordered mine from eBay that look like Item# G5716. What the heck do you use that tiny 3/16" tool bit for? I'm afraid to even try it.

That's my favorite flycutter, I use it for small parts or in steel where less power is required from the spindle.

Really? I didnt even form the blank. I keep it handy to cut burs.

Grinding is a little tricky, but a dremel helps with it. For the little ones I like a very small corner radius, and a fine point. Delicate, but also good for undercutting shoulders when used as a form tool.
