Not quite sure what went wrong George.

I know that MDF is horrible stuff to cut compared with hardwood as the tool clogs up instantly. I did suggest reducing the feedrate for the first cut to reduce this problem but I must admit that I have never tried to cut the Gemme plaque in MDF.
Perhaps two passes at 1/2 depth each may be the answer.

Show"N"Tell ( Your Machines) / The Laser Project.

« on: August 26, 2009, 02:48:48 AM »

Now the shadows are starting to lengthen I am preparing for my next winter project - To add a CO2 laser head to my existing router. The output power of CO2 tubes is related to overall length and the size of my machine dictates that a 600mm length tube (which is rated at 30 Watts) is the largest that I can easily accommodate.
These tubes can be something of a ‘white elephant’ insofar as that I suspect more people buy them than ever get around to completing the project. When you start to investigate the additional parts that are necessary and the cost of those parts, I am not surprised.
However I have started so I will continue.
Initially I have had to add a mounting space to the machine and some more box section with a bit of welding has produced two brackets which have been bolted to the rear of the machine frame giving a position to fit the laser stage. I have also milled a pair of tube mountings and made bungee straps to secure the tube in place.

More to follow…….

I would appreciate your comments and advice on this project as the more info I can get the better.

Chris, slow down a bit, chill, you are just way too productive. Remember 'supply and demand' or you will flood the market and prices will fall.

Do you know, I have been doing 'percussive maintenance' for years now and I never knew what it was called.
Thanks.

Nice work.
I love the CNC mallet in the background.
