Think it should just about be able to cut a bit of acrylic - will be a pretty expensive mistake if it doesn't.

Hi George,

Any chance you could post some pictures of your machine, would really like to see them.

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.

Hope they are not left handed like the pictures show.

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.
