Laser cut parts

[RocketManDan]

I'm going to upgrade a couple kits I have and I need some parts laser cut.

Who would do this work? I'm thinking about replacing the balsa wings and parts with lite ply 1/8" I don't see that it would add much weight. Also upgrading the center rings with lite ply.

Dan- Balsa Machining does great laser work and they are fairly inexpensive-fins and rings.

+1 for BMS.

 

[RocketManDan]

Yes I was considering BMS. I was considering getting some rings made to for a few other kits. On the wings I still need to fill out that excel spreadsheet right? Does Bill work off Rocksim??

 

[Worsaer]

Yes, they will use Rocksim files. I used BMS for custom fins for the first time a couple of months ago and could not be more pleased.

Is that anyone that does custom work in G10?


All the best, James

I notice BMS is no longer doing custom laser cutting.....

Anyone have a suggestion for an alternate? Need to cut some 1/8 Carbon Fiber sheet................

That's temporary til they get their new shop set up.

Carbon fiber sheets can't be easily cut with lasers. The fiber it self has a very high melting point, but the glass temperature of the epoxy matrix is much lower. If you throw enough power on it to cut the carbon fiber (i.e. much more than your average laser cutter), you likely damage the epoxy matrix far beyond your intended cutting area. I guess it could be done with very short and intense pulses that "instantly" ablate a small spot before much heat can be conducted into the surrounding material - but I'm only speculating here, based on something I believe to have read on dental lasers.

If you want to cut carbon fiber sheets, water jet cutting is a standard method. CNC milling works too, but it can be messy.
