Never seen this before. Would you use it for rosette channel cutting? Looks like it comes with a circle cutting attachment.

I can tell you this, I bought a proxxon table saw for some fine cutting for guitar work and it turned out to be too light duty for our needs. It really couldn't handle dense hardwoods or shell.

I think this stuff is made for the model world.

It was a vrey nice tool, but just not right for our applications.

Hi Todd.

You can make a mini plunge router for a lot less than $200.

I checked out the StewMac reverse-plunge router (Dremel) sound hole cutter unit, (before they offered the micro adjustable one) and decided to make one.


The key to the cutter sliding straight up and down is to use telescoping sections of brass tubing. The bolt inside the inner tube fits pretty snugly as well.

Configured as shown, it has the upper springs holding the router into the fully plunged position (and the lower springs serve to apply pressure on the adjustable depth nuts, to keep them from spinning, but make it easy to adjust.) But, if those springs and adjustment nuts were reversed, it would hold the router up (and then it would be a true plunge router.)

Let me know if this helps - I have other pictures if you want to see more.

Todd, there's an electric guitar making book that I have, and in it the guy
is using what appears to be a laminate trimmer-type router with a plunge
mechanism. I was very curious about it when I saw it, but couldn't tell
what type it was. The guy is German, so I'm sure it's a Euro model.

Anyway, I know this isn't much help since I can't remember the name of
the book at this moment, but I'll let you know when I get a chance. I've
thought about contacting him myself, but just let it slip by the wayside.

Todd, I don't know what you are looking for, but take a look at this.  It looks to me like a pretty good way to make your laminate trimmer into a plunge router.

That is a fantastic tool. I use mine constantly.

It ain't cheap though, and as I looked around at the purchasing info, it is also not currently available to ship.  I noticed that LMI also has a plunge base for a laminate trimmer - also unavailable - hummmmm.  Any connection?  LMI's is cheaper.

I think Bishop makes these as you order them. They all take a little while. I think I waited a month or so on mine.

Lance just bought one, he had to wait a little while too.

They are worth it though. I know they are really expensive, but it is worth it. It is built like a tank.

The Cochran base is not the only game in town. Though no less expensive, Micro Fence now also offers a plunge base. It is also available for a wide variety of tools.

Todd,

This was made as a rosette/soundhole cutter. I was too cheap to spend $80 at StewMac (and it was before they had a unit with micro-adjustability.)





The brass tubing available at hobby shops has excellent telescoping (linear bearing) capability because the ID of one and the OD of the next fit so well. You may not want to mess with it and take the time to do it, but with some brass tubing, epoxy, scraps, and $10 at the hardware store, you could make a plunge router base for a laminate trimmer.

You have me curious what use in lutherie do you have planned? I can see a lot of potential for routing in solid body electrics, but I can't think of much it would do for acoustics. Slotted peg heads? Just curious...

This would be cool but I can not seem to find where to purchase one in the US http://benchmark.20m.com/reviews/TrendT3Router/trendt3router review.html
I may check out the proxxon as I am looking for something for light duty tasks (i.e. bridge slotting, etc). I would like to find something more substantial than a dremel type tool for these tasks. Otherwise I guess I'll have to drop the $$ on a Bishop Cochran for my 310.

The router that Kahle just posted the link to looks just like the one I saw.
