Re: Faster? Well, kinda :)

Hi George, no doubt heat from the motor is a risk, but the fin can will be isolated from the motor with masking tape. Hopefully this will be enough to avoid any significant issues...

Re: Faster? Well, kinda :)

I did another one in red ABS this time, but what a waste of time that ended up being! The ABS is significantly less rigid, softer and downright weak. Not sure how it is that the numbers are similar, because the actual truth seems to be very different. I think I could probably crush the tube with one...

Re: Faster? Well, kinda :)

Here's the 54 version now. Wondering if I should make a single-fin on a sector of the tube for mechanical testing (i.e. pull on it until it comes off). The 3D printing process relies on an imperfect bonding of the layers. This is very different from say an injection molded part where you can be pret...

Re: Faster? Well, kinda :)

Agreed Noel! The time will come. Just look at laser cutters. 10 years ago only large corporations had them! It seems to me that 3d printing (by way of heat fixing layers anyway) only really works with materials that have poor heat transmission properties, hence why it works with stainless steel and ...

Faster? Well, kinda :)

I'm always interested in ways to speed things up and, in this case, what I'm doing is hardly new or particularly cool, but it certainly does speed up the manufacturing process. I'm waiting for the new nylon 3D printing filament to arrive and thought I'd mess around with the PLA filament that I have....

Re: MARS Attacks

Low and slow. :( I don't think that's me. I'll take my chances with the cloud cover :wink: We all get back to those eventually, e.g. I fly "low-and-slow" as often as I can, and with pride every time! ; especially when it is for the right reasons! Rocketry in Vic will be great again :) See...
