LaserUser.com Forum (formerly RDWorksLab)

I just cut this from a ,75 common pine board as a test. I am either suffering brain fog [confusion, memory issues, etc] or beginners Alzheimer's and I try to keep doing mental acuity tests to keep score. My sweetie collects miniature chairs and I have made few for her and was trying to find something that would be challenging to design and laser cut. I am impressed. Gotta go home now but will post a how-to if anyone is interested. No sanding- just a small wire brush prep. Gene

Hi Gene,

It looks an impressive design.

What power / lens are you using to cut 0.75" pine board?

I have a 130w tube from LightObject in Calif [they test each tube and it rated at 150w] and a 2 inch lens. Speed is 4mm/sec and I overdrive the tube for special projects [ rating is 28 mA]. I sold my company and the new owner lets me have a corner of one building and is happy to buy new tubes when necessary. It is a profitable business that I built from zero. I have had the Laser since 2015.

Looks like it's me and you Gareth- I am putting together a mockup of the chair- the seat is .375 Alder as well as the rear leg taped on- it will peg into the upper part of the back. The Alder ccomes from a hardwood company in a neighboring state- very nice and consistent wood, but semi-expensive of course. the chair will be 5.5-6 inches tall and is my most elaborate one yet.

Hi Gene,

There are a few new joiners each week, but not many contributors.

Once I get a chance, I'll do some mail shots to registered members. But I suspect a lot have moved over to the LightBurn Forum.

Next thing for me to do is to complete the change over to LaserUser and open up the other sections.

I believe the forum is working better, faster and has some new features, it's just marketing it again.

If you have any recommendations or bug bears about the forum, please let me know.

Russ mentioned that overdriving a tube may actually reduce the power output of a tube. He also had his best cutting results using a 2.5" GaAs lens.

Hey Gene,
Good to see your still around and still at the miniature furniture.

Good to see/hear from you Willie. Are you still using the rotary Mashup? We would love to hear about more of your laser adventures. Gene

Thanks for the reminder on the 2.5 lens- I am battling memory issues the last couple years and have tried to keep busy as therapy.

Yes, in fact it is the only rotary device I use since you helped me build it a couple years ago. Works great
I am looking at buying an Atomstack 24w diode laser for very fine detail (mainly photos) and may purchase the rotary with it for cups with handles. Still doing research.
Retired a few months ago so trying to get back to lasering more along with long list around home and shop. Hopefully will have more time for stuff like this soon.
