I built this whole thing for less than $200.00 and I'm happy to report that it actually works. It chatters quite a bit, but i think that is normal when trying to sharpen a square stake into a round point.
Has anyone else built one from scratch?
Thanks,
John B

Looks like it works well !!

Good looking stakes.

Good job John, do the shavings eject freely or tend to bind.?? good looking points. Frank C.

Hi Frank,
Thanks for your help with this thing.
The shavings seem to eject freely when it's warm out, but I tried to use it Tuesday night when it was 19 degrees out and the shavings kept freezing in it.
I had to ditch the first set of knives in favor of some 1/8" thick ones. The jointer blades that I started out with cracked after about 40 stakes.
Thanks,
John

I always wanted to build a pointer but never could figure out how to make the cutter head.  Did you have plans?

Nice job on the build. :)

Great job. I love to see homemade equipment. Looks like it works better then a commercial one for 1/10 the cost ( we never count labor ). Do you use 1 blade like a pencil sharpener or 2 opposite each other?

I had a plan in my head, but nothing on paper.
I want to run a few thousand stakes through it to make sure that it's safe and I didn't overlook something.
After that I could draw up a set of plans and take detailed pictures of the cutter head, if someone wanted them.

Two opposed blades. It chatters a fair ammount even with two blades. I think if it only had one blade turning 3000 RPM it would chatter like mad and break the stakes.

Nice job!!!! That kinda looks like my Jet 920  lathe with a backsplash! I was making aluminum bushings today on mine for a gunbarrel vise. I always figured making gradestakes was one of the best uses of hardwood pallet wood,that and flooring,not much waste there. Don

Im suspecting, you used around a 35 deg on the cross slide?,  I noticed you dont have any reliefs so the chips can eject as it peels.   Studdied to make one and ran out of time,and access to a lathe.  The blade needs to be at a compound angle, one to cut a point,  and other the blade pitched nose up, but the cutting edge not above centerline.

Yes, I would want them vary much.  The design, in many cases, is the hardest part of the job.

I used a 15 degree angle, when you sharpen the stake all the way around this gives you a stake with a 30 degree point.
After i took the picture of it on the lathe, I milled two 7/16" slots in the sides and mounted 1/8" knives in the slots. This leaves a 5/16" opening for the chips to eject. The cone goes from 5/8" up to 3" so centrifugal force naturally ejects most of the chips out the end of the cutter head.
I like your idea of a compound angle. My blades are mounted on a 15 degree angle, but are not pitched nose up.
If I end up re working the cutter head I will follow your sugestion about the compound angle. My design works, but it chatters, if I had the blades pitched nose up, I think that would solve my chattering problem.
Thank you for your input,
John B

Three blades, not equally spaced. Perhaps 110°, 120°, and 130° apart.

John, a good solid vice or clamp should reduce the chatter as close to the tip as possible. The chatter doesn't seem to have effected the points. Hows the balance up to speed. ?? Frank C.

I have thought about building a pointer using a cone hole and a stack of the cheap 7 1/4" carbide tipped saw blades. A cutout in one side of the cone for the saw stack to mill the point as you rotate the stake, with good gloves of course. Probibly a square hole turning slowly would be easier on your hands to turn the stakes. Frank C.

John, are you feeding the stake in by hand?  What's your typical M/C on the wood?  This build looks innovative.  I use tenon cutters on both a press and with hand held 3/4" drills.  The chatter is trouble and usuall degrades my tenon as well.  My simple fix was to soak the end of the wood for a few minutes in a pail of water; much smoother cuts with the chatter greatly reduced.

i suspect the with the blades straight across, its rubbing and not peeling.   you'll notice tear out vrs smooth surface on the wood.   its like turning metal,  slight nose up on the carbide bit smooth finish,  straight across its pitted and chewed
