Heres some pics of my homegrown flycutter tool. The dirty engine in the car is mine. The shortblock on the stand is my buddy My90Iroc's.

Its a couple pieces of steel turned down on a lathe to the proper size (2.125 and 1.675). The shaft is a 5/16 bolt with the head cut off. The collar was bought from mcmaster for under two bucks. We used adhesive backed sandpaper, first in 40 grit, then in 100 grit to touch it up. The depth was set using a nickel for a .075 deep cut.

Take a look:

Good job. Did using sandpaper take much longer to cut than using a cutter? How many adhesive pads did you go through for all the cuts?

It took maybe 10 seconds each with the coarse sandpaper and very light pressure on the drill. Then we touched up each flycut with the fine grit for a couple seconds just to smoothe them out. We used one coarse and one fine piece of sandpaper for each cut. by far the hardest part was peeling the sandpaper back off with a razor. All in all, it was very easy.

yee haa!! That is what I am talking about

I cut mine also, but I used the Isky tool... Looks good...

That's awesome! What did you have to do to the mockup head to make that fit? Anything?

I sliced the valve seats with my angle grinder, then I pried out the seats with a screwdriver. I bought a junk head to practice my porting, so i didnt mind ripping out the seats. I also sat the head on old .060 GM MLS gaskets.

Good job on the innovation. I used the isky as well, didnt turn out any different than yours.

Could a valve be used instead? Maybe a larger valve from a Gen IV LSX motor? Cut teeth into the bottom face of valve. I assume that is what you did to the piece of steel that you used?

I originally cut teeth into the steel disk I used, but it proved to be far too soft, so I used the sandpaper disk instead. You could try using a valve, but it may be too large to fit up in the valve bowl, and even if it does, it may not stay sharp more than a cut or two. The adhesive sandpaper works pretty well and is easily replaced between each cut.
