Very Nice Work. and again, thanks for sharing your ideas and work. I love seeing things that guys come up with on their own. If I can make one of these killer tools, I'll be really psyched!

Three thumbs up! Nice lathe too, my dad has that one it looks like brand new! It's 35 years old!
Can't beat them old Craftsman tools! I got a original completely METAL router that I still use! Bet it's worth $$$

I built this one a while back. I've had very good success with it. I found that keeping the tool square to the work was the key to transferring the template shape to the blank.

Digger,

I like your setup! Keep it simple. Thanks for the idea of using plexi for a template and where to get it. I think it would be more durable than the wood I am now using for templates.

With the duplicator I built, it is not critical to keep the tool square to the plug. The guide has the same profile as the bit, and is directly below it. As you twist the bit it still positions itself by the guide directly below it. The design is borrowed from a commercial design I saw 20 years ago and haven't seen since.

Thanks fishing bum wannabe for the tip

. Here's my creation that still needs some fine tuning. The cutting blade is the trick. I'm still in search of what to use but for now, I'm using an old drill bit.

i also made one over the weekend, made 14 darters out of maple, came out pretty good, have to refine the cutter, had to sand a little more than if i used a skew to finish. i basically used my turning chisels mounted in a holder like FBWB showed. reallyappreciate you sharing this simple but effecient jig

Nice lathe Rich

got one just like that. Cool duplicator too. If worse comes to worse, you could always get a cutter from Pennstate Industries. They sell the spares for their duplicators.

li., the cutter on the duplicator I have does not leave as smooth a surface as the skew. Probably not a problem with your design, just a factor associated with the way the cutter has to work. If you need, just use the skew on a final pass or just spend a little more time with 60 grit sandpaper. Make sure to set up the template to allow for the extra sanding.

Rich / In2Bass · 01-28-2003, 08:04 PM

Thanks Jigman. I still have to work on the proper centering of the template with the cutter. Its just been too cold out in the garage the last few days to think straight. Hopefully I'll iron out the bugs.

fishing bum wannabe · 01-28-2003, 08:27 PM

Rich / In2Bass,

Nice job! Send me your address and I will send you a tool steel bit for the duplicator. I have a grind that cuts a shearing cut moving right to left that is faster (up to 1/8" per pass) than the Carba-tech or the Vega. Going left to right it gives a smoother scraping cut. I am sanding with 60 seconds with 100 grit with an additional 10-15 seconds with 150 grit. You shouldm't need 60 grit.

The key to accuracy is to keep the tip of the cutter and the tip of the guide in vertical alignment, and the tip of the cutter and the tip of the center at the same height. Do that and you will find that this works very well.

l.i.fish.in.vt, I would be happy to send you a bit as well.

Key to this being accurate is to have the tip if the bit being in vertical alignment with the tip of the guide pin and at the height of the tip of the bit to align with the tip of the center.

Fishing bum wannabe - I have the tip of the cutter and the tip of the guide in vertical alignment, and the tip of the cutter and the tip of the center at the same height. I just need to figure out the correct placement the template that lays in the backend.

fishing bum wannabe · 01-28-2003, 11:33 PM

The template should be immediately below the plug. You may need to do some tweaking. I use two screws with knobs to hold the template. I drill the holes for the screws through the template oversize so that I can adjust the position until I get it just right. Start out with the template towards you so that the plug will start oversized. Then slowly move it back away from you until you get exactly the size you want. Then mark exactly where the template is in relation to the table so that you can take it off and then reposition it later. I have more trouble locating the template in relation to the headstock so that I get the plug on the blank I cut.

This pic is what happens when you get proficient with the duplicator. I never did this many of one plug when I was turning them by hand. I might have done 6-10 in the time it took to do 27 with the duplicator.
