CarveWright-Feed

[bob2251]

Has anyone tryed a feeding setup like on the CarveWright machine (Sears Compucarve)

The feed uses a sandpaper type belt with rollers on top with 80 lbs pressure to feed up to 12 ft. long pcs. I would like to set something like this up. Need more info!

Have you looked at the www.phlatboyz.com site?

I think they use a feed roller?

It should be pretty easy to do. The bed will need to be either very slippery, or made up of rollers. If you use rollers, you made need to mount thin stock to a thicker backer board.

Then make the feed roller a spring mounted assembly containing both the roller and stepper that drives it.

One problem with this is that it's limited to flat stock (or very close to it). Also, you might have trouble near the ends of the machine.

And how do you keep long narrow pieces from moving when making a lot of back and forth movements? Seems like some error could creep in here pretty easily.

I like what phlatboyz have, but this is what I mean http://www.cnczone.com/forums/attach...1&d=1236577470

Re the support for thin stock/non-flat/slipping, how about using a vacuum bed as a moving table with the edges only (top, bottom and sides) engaging the rollers ?
A length of 1" wide emery cloth along each of these faces will hopefully provide sufficient traction.
For the table, I propose to use a hollow door for its size/weight/cheapness.
This is what my own #3 machine will use, if and when I get the #2 finished

Your idea sounds good. If you look at the drawing this machine has NO table , it just feeds the wood. I think rollers on the bottom and top with a rubber belt and bngs. on the sides. If you go to the carvewright site you can dowload a pdf of the parts manual and see what I mean.
