I consider this to be pretty good. We do some things pretty much the same.

Makes me want to go out and buy one.  I have been very hesitant since the reviews are not all that good.

Any one who has used is has sworn at it, even if they didn't say it out loud. Those who know how to use swear by it as being the fastest and most efficient. It does have a learning curve.....

I bought mine about a year ago. Immediately ordered Robo's video, watched it several times. Went out and cored my first nested set, successfully. Bought Mahoney's video, picked up a few pointers from that video as well. So far, 8 - 10 corings and no funnels.

Just finished watching Dale's video and added a few more arrows to my quiver with the information he presented.

Learning curve? Yes! Bad tool? No!

I bought mine when I had a Jet 1236 and used it successfully. Surprisingly I had more problems on the first try when using it on the PM 3520.  I quickly learned that I had to hold back to prevent the cutters from self feeding. After that all went well.

Very well done. I have watched Mike M's video and others on the web as well. \this one really helped me put it all together in my brain.  The time spent on explaining the lay out and visually picking a target for starting the cut helped me the most. I bougth the tool and my lathe was too small bang head to power the bowl saving activity. I upgraded my lathe to a Vicmarc 300 Smiley and now the speed control is much more repeatable and doesn't change when cutting. I will be out there in my shop coring out blanks with confidence to try these tips. Thanks for sharing.  smiley=dankk2.gif

Out of the box there is a learning curve.  I tired to error on the thick side so I didn't make funnels.  I like it and it has made a grunch of bowls where without it there would be chips on the floor.  It is well worth it!  I wish I had any video when I got mine, this explains allot that they don't tell you about positioning.

I bought my McNaughton about 3 years ago and I have had varying degrees of success.
I know the majority of this is due to set up.
However, I believe my post is too long as I can not quite get the cutter directly on center.
I have a Jet 1642.
Anyone else notice this?
BTW I have only had 1 funnel....
Clearly my fault as I took a deeper than ordinary plunge...bad positioning.

Is the post bottoming out in your banjo? Or is the top of the banjo hitting the bottom of the swivel? Either way it sounds like hacksaw time on one or the other.
On my lathe I am lucky to have enough room to use a clamp collar to set the height.

The post bottoms out on the locking post for the banjo.
I am thinking about 1/4" removal.

Jeff,

I have a Jet 1642 also but I have about 1/16" to 1/8" of "play" between bottoming out and dead center.

Just this week I checked it using Dales method of using the straight blade to find center and I was dead on with still a bit of movement left before bottoming out.

Hmmm, I had to get the weird post and lathe! LOL
My dad has an old Atlas Metal Lathe and I am going to take a little off the bottom of the post.
I have cored quite a few bowls as it is, but I think this slight modification may help.
Today, I cored honey locust and it seemed to be good.

I manufactured a new post today rather than mutilating the original post.

Just sat down to watch this video. It got stuck about 10 minutes in. Didn't get to any of the good stuff yet. Cry Cry I'll have to try again tomorrow.
Cool

Went back and manually moved the point where it stuck on me.  Watched through without interruption.  Some great points.  Again, I learnt something.
Cool

I have posted these observations as a review of the Kelton on a couple of dealer web sites. Take note Larry on my comments about the blade sizes. And I plan to glue my funnels with a new base like a laminated turning.

Set-up and use the system correctly - it will be a dream to use. Incorrectly set-up or use the system - it will be a nightmare.
Please read my notes about blade sizes at the bottom! I feel that many issues with the Kelton are because folks are using too large a blade. You also need to run the blank fast, pulley 3, ~600 rpm on the Nova 1624. I was running pulley 2, ~300 rpm, and the chips weren't clearing, the tool wasn't cutting well.
The vendor support is fantastic. I had an issue with a blade not feeding and Kel called from NZ. The solution was to lap the blade to remove the high spots.

You do need to read the information on the web. Watch and rewatch the videos - Dale Bonertz video on youtube and the Mike Mahoney DVD.

Dealers really should package the standard and small blades as a set. Lee Valley does this.
I initially got the standard and jumbo blade set. Then quickly added the mini and small blades. The jumbo blades were too big for the blanks I was coring. With smaller blades and a faster speed, at least 600 rpm, the tool works fantastically.
You also need to replace the handle with say a 16" Sorby - I didn't need any inserts. The included handle is too long and too heavy for anything but the jumbo blades.

Right on the bottom of the Kelton product page
The Micro system has been designed for those whose work is probably in a size range from 100mm to 200mm (4" to 8") in diameter or those wishing to take very small cores as part of nested sets where larger blades are used for the remaining cores. If you typically work with blanks in the size range 100 mm to 250 mm(6" to 10") diameter, then the Small set will probably fulfill your needs. For work in the 200 mm to 350 mm (8" to 14") range, then you might opt for the Standard system. If you routinely handle work in the 250mm to 450 mm(10" to 18+") diameter range, then the Large or even the Combo would be preferred.

If your post is only 1/4 inch high, I would leave it. For setting the proper height, yes, use the longest blade fully extended, yes, lift up on the handle, and lift hard. This gets you close. What it does not include is the cutting pressure on the blade when fully extended. If you have ever tried to remove the stub that is left when the core breaks out, the blade tip can be 1/2 inch plus below center. Not a problem with most cores, but if you are trying to cut the core all the way off (good idea with burl, and mandatory with end grain so you don't rip through the bottom), you need to be up higher. The cutters are scrapers, and with scrapers, on the inside of a bowl, you do want to be slightly above center. Too high, and the vertical part of the blade will not fit into the arc of the kerf.
