Topic tags/keywords: laser cutter question

I need (ok, want is a better word) a laser cutter so I can offer more detailed images on my Mash Paddles that I make as well as other woodworking products.

Here’s my dilemma…......

While the images I’ll be carving aren’t big (3×5 inches max), the item that I have to cut on averages 50 inches long by 4 inches wide.

Imagine having to cut a logo in the middle of a 4 foot long 2×4.

My CNC Router can easily do this as its “Y” Axis is totally open on both sides which allows very long products to be affixed to the table – It can only carve 18” of this area at a time, but that’s just fine.

Anyone know of a laser machine with open sides or the ability to be placed over an object?

I’ve seen a product called “Mr. Beam”, but have no clue on how to purchase it.

Oh yeah – reliability / ease of use would also be a good thing! ;-)

Thanks!

Kern lasers sells what you need. It’s doubtful you’d be able to fit one into budget unless you’re selling a lot more volume than I assume you are.

JAAune,

You are correct x 2.

That would indeed work, but WAY too expensive and too large of a footprint!

Thanks!

Actually, the footprint isn’t too bad. They sell the Micro models which look to be bench top models in 4×4 size.

Still very pricy I’ll bet. Probably at least $30,000.

I’ve used one of these from FS Laser in the past, and I believe the bottom was removable. If you set it up over a slot, you should be able to slide your wood through underneath it and engrave in sections.

Make sure you get the air compressor to blow where you’re cutting, and adding a bigger exhaust fan to ours helped immensely with keeping smoke off the mirrors/lenses. We just built an exhaust tube out of MDF with a 120V vent fan in it to suck all the air out of the cutting chamber and blow it out a nearby window.

Tim,

This may be exactly what I am looking for!

Thanks – I’m going to check this out.

Seeing the pics of it on a car hood most certainly intrigues me. ;-)

Mind if I ask how reliable this thing is?

Cheers!

Bob, as long as you keep your lenses and mirrors clean after they get smoky (probably wiping them down weekly will be fine), it should work for longer than the estimated life of the laser tube you get without issue.

We had a problem where we let the coolant in the tube freeze and it cracked, so if your shop isn’t heated in the winter you might be wary of that.

Otherwise we’ve had no issues with over 300 hours of cutting time in 2 years on the new tube and no signs of stopping.
