you want one of these then.... http://www.uafproducts.com/reaction-pattern-generator/ dave got one and i was playing with it a bit. It holds shape exactly. Its basically a flexible hard rubber with metal inside to keep its shape.

Well, I decided to just buy these. I went through the paypal process and the total shipped came out to be $110!?!?

holy hell! I was fine if the price was $89 shipped but after adding 9% sales tax and $11.95 shipping... I'm out on these.



Any other ideas? Does anyone know if the 12vtools flexible templates hold shape when being removed? This thing is pretty much what I need but surely there's got to be something that doesn't cost me $110...

Reading around, these flexible rulers with lead cores are supposed to be pretty good at holding shape and that may be what the pattern generator essentially is. For $10 shipped, saving $100, I'll give it a go. I'll post up the results.

I didn't realize what you were wanting it for at first. I've seen a tutorial using the template like Joey carries, it's basically a bunch of thin laminations that are held static at one end. When you flex the template into the shape you want it, you lock the laminations in place by putting tape on the edge, so the laminations can no longer slide by each other.

As mentioned before, you'd also need the special router bit with the square bearing to keep from melting the template.
 
it wont hold a perfect shape like what you are wanting Erin. Even after taping the end locking the laminations in place, there is going to be a little bit of movement. You could just do it the old fashioned way and cut a but of curves and straight pieces using 1/4" mdf and CA glue them together in the car. Then you use that as your template with a multiple bearing flush trim bit. That other flexible thing you bought for $10 looks nice, but I'm wondering how it will hold up to a router bit.
 
But, as I mentioned before, I don't need it for routing purposes. Only to make a transfer to wood.

If the blue thing works out for my needs I'll let you guys know in case someone else is in the same boat in the future.
 
Why not scribe a line on a piece of cardboard or thin mdf? Put a straight edge of whatever material against the profile you want to copy, make a 'puck' with the radius equal to the largest gap, drill a hole in the puck for a pencil, and trace the profile onto the mdf or cardboard. Repeat for the other side, and lay it out at the proper distance from the first profile you did.

edit: I used a ruler with a pencil taped to it, but I found it difficult to keep the ruler exactly horizontal as I traced the profile, so I had a bit of trial and error getting it to fit just right. The puck should eliminate that error factor.

those are all fine options. I was simply looking for something that's made for this kind of task. the item Bob linked to certainly is... but it's cost prohibitive. I'll try the $10 thing from Amazon. if that doesn't work, I'll go with the old cardboard method.

Missed that part. This blue thing should work great for you then. The trick Jason mentioned is good too. I usually just use a pencil and a metal washer to scribe lines/curves on cardboard for transfers.


Erin, not sure if you have seen this video, but at 1:50 in, you can see Mark using that tool from Joey you were asking about.
