Anyone have a good option for holding down 2 boards with the 13/15 machines for the purpose of cutting all the way through?

Today I learned that if the wood is lower then the screw it will not cut.
I was using something 1/4 inch and first it moved up, flipped it over put one of the clamps in the top slot causing the wood to move down, well the plate moved and the wood remained in the same spot. Cut would have been .118 so enough room before hitting the plate.
I'm thinking maybe using one of those small window clamps, maybe metal.
Maybe I'll try to print something on the Makerbot.
Or replacing the stock screws with longer ones for thinner wood.
This experience makes me wonder just how well double sided tape actually works on thin through cuts.
It suggests that the top thin piece would slide

I didn't try the tape I just ordered the ones you found even though I have seen the tape mentioned in several forums before.

As far as complete thru cuts, I've seen a video of a cnc machine doing thru cuts in which the item being cut-out had been designed to have connecting tabs to hold the piece steady, and then after cutting, one could cut off the tabs with a scroll saw. And of course the wood was attached to a sacrificial board beneath.

I think a carriage bolt of the right size to fit the slot would work nicely. image.made-in-china.com/2f0j00sClEYGNBnSge/Carriage-Bolts-DIN603-.jpgAll it requires is a drilled out piece of wood and a nut to clamp everything down. I also consider a carriage bolt for either end when the space is too narrow for the regular clamps. I'm really kind of baffled as to why the supplied clamps were considered the best choice. You would think something open jawed higher at the top, or even slotted allowing the upper part to be re-sized to adjust the extension of the clamp, would have been a better option. That driving a screw into the wood seems a bit limited and lacking creativity. |

I did a through cut a couple of weeks ago using the software Cut2D from vectric and I was impressed, I will add the machine was cutting kinda of fast in the Y moves I was cutting scrap 3/8's plywood and I could hear it slowing down the spindle for a moment.
When I do it again I will make more passes with shollower cuts so I don't bog the motor in some thick wood or worse break a bit off in it!

Not 3/8 in a single pass, you set the program your using to make multiple passes deeper and deeper until it goes through.
In cut2D you can put little tabs on the part to be cut so it is held in place on the last pass and you just use a jig saw to cut those out.

Well I got my clamps in the mail this week and I REALLY like them I think they are worth more than the 10 bucks I paid for each one.

Hey Greg, which clamps did you buy? Are they the INCRA brand clips Yes the ones in the link above and they are bigger than they look in the pic. I will be able to easily clamp two boards down at the same time if I want to cut all the way through or just cutting thin stuff. Plus they look cool too! |

Awesome looking clamps, I will have to get some once I get my machine up and running again.
