Default Any one using Pin-It or simular pin router attachment

Hi,

Is anyone doing any pin routing? If so is the arm made by some company or homemade, and how well does it work? I've seen it in books and it looks like fun but I don't know of anyone that really uses this method.

I bought one of these and found it hard to use it keeps moving around and no way to make it solid.
Would not recommend it.

I did decide to try one, and you know the one I got did not work well either. I tried making 3 pass each one a little deeper then the previous around a pattern I had made. I tried making a full depth cut, a little better result from the pin arm but the cut was way to heavy. Having every pass a bit different then the one before or having to make such a heavy cut made it useless for what I wanted.

I returned mine to the catalog place I got it from and got my money back, even on the used 3/8" spiral bit that came with the set. They would not comment on how many get returned......

I like the idea, I like how it looks like it will work but it will have to be rock solid to work right. So it is either spend a lot more or do my own.

I guess I should have answered my own post to let other know what I found out, sorry.

Ed, I bought a custom built pin router from a friend. He built this unit himself and used it while a toolmaker. The only bad thing is its not easily height adjustable for accurate plunging. Im working on a solution to that.
I also found a plan on the web for a home built version. The file is too large for posting (309K) and cant be reduced without losing detail. I would be happy to forward it to anybody who is interested.

I looked at these for a while, but really you're just following a template on the opposite side of the workpiece with a pin the size of the bit instead of a template guide on the same side of the workpiece with a guide 'slightly' larger than the bit. Plus, you are adding whatever movement exists (no matter how small) between the base, stand, and arm as a cumulative error when following your template. You still have to make an accurate template, even if it is duplicating an original piece. And if your original has roundover edges, your chances of accuracy decrease even more.
I decided it was just as easy and 'possibly' more accurate just to make an MDF template pattern in the first place and use template guides. And I know that the pattern/bit relationship will not change as I am moving around the edges.
Just my .02, your milage may vary.

I would be interested in the plans, do you have a url I can get it from?

How about a picture of the one you have? And how well does it work other then the stated issue?

Thanks for your comments, my first try at buying one showed me the need for it to be made solid and strong. I still like the idea but.........

Tony, when I was introduced to the pin router by the guy who built it he had other ideas of how to use it. Freehand sculpting by moving the wood as opposed to the bit was the way he used it. Points to consider: The pin router stand I have is rock solid. You see the actual cut like portable routing or using a template, some people feel they have more control moving the wood. Equiping the table with a fence allows regular table mounted operations with the look down perspective. The pin router feels more natural to machinists who are used to milling operations. I know its a case of apples and oranges. I guess its what you feel most comfortable with.

My biggest selling point was this: I paid $40 for the pin router which included the Rockwell router, wrenches and 20 assorted bits.

Ed, I will take a pic of my pin router and get it posted asap. Outside of no method for accurate plunging it works great. I am asking Mark for a way to post the oversized image of the homemade pin router plan I have.

Mike,

Are you talking pin routing or overhead? I'm interested either way. Here is another post to the past when I was asking about overhead routing:
