Slow Build Austria / Salzburg

Can I ask how much did you pay for this board ?
It seems a good shape and hole looks great too !

It was a prototyp, i payed 400.- for it.
The company is a Startup, based in CZ.
The boards for selling from theme, made in Carbon costs around 800.-

I also use the Anycubic Chiron. It’s a good printer. But I made a few modifications, which improved the print image even more.

On your propeller I also see potential for quality optimization with the right settings.

Overhangs up to 65° are possible without support.

The blades look thin, I suspect they will break. I have had a good experience with my impellers with a blade thickness of 3.5mm and PLA pro.
PLA pro can be post annealed in the oven. It is then harder than ABS. And very easy to print.

So, Mastclamp is finished printed.
I use 1,5mm wall thickness and 0% infill.
I will fill it wish Epoxy and 3mm Glas

So, I use the chance and get one of the last FR Props. So, will be interesting how big ist the difference between my DIY Propeller and the FR Propeller.

Tip for your next prints: If you use a 0.4mm nozzle and the layer width is set to 0.4 in your slicer, the wall thickness of your part should be dividable by the layer width. (1.5mm /0.4 will result in 3 layer and some gaps between the walls. 1.6 mm / 0.4 gives four walls and no gaps.) So you get better print results and well connected layers. Wherever possible, it is best to take into account during CAD design that all walls can be divided by the layer width.

All is fitting perfectly…

Do they have the same diameter so that they can use the same (orange) duct ?
One remark: shouldn’t your duct leading edge be round and thicker that the trailing edge, the way a thin airfoil section is, here an Aquila 7.4% that seems to be well suited for a duct as it is nearly flat on the intrados:
Aquila9.3 and 7.4  smoothed

Yes, they have the same diameter. I take care for that when I construct my prop :slight_smile:

No, sorry I reading wrong. The Duct is on the leading and trailing edge thin. I try it with a profile and the results was good. I will see

Next step is done…

I decide to print the box for the Akkupacks.
As spacer I use the Vruzend because later I can easy change from actual configuration 12a12p to perhaps 14s12p or other configurations.
On the picture you see the bottom plate from the box. The Vruzend spacers fit exactly into :slight_smile:
I will mount it on a 2-3 mm aluminum plate.
The cover from the box I want to laminate with Glas or CFK.

and here the CAD Rendering…

After some days printing, the cover from my Akkupack ist finished.

All is fitting perfect and the cover is strong. So next step is to laminate the Cover. So I can learn to laminate with CFK and Epoxy and later I can use my experience with the Mastclamp and the box for my inflatable.

Hello , nice work :slightly_smiling_face: one thing about amazon époxy it’ is not for surf just good to wood gloss … you need to buy it in a surf shop online or in a local shop to be sur of the qualitee what you need and for the carbon fiber be carefull lot of dealer sending it folded the fiber is delamined and not always in good states …the fiber need to be rolling to arrived clean…some post speak about resine qualitee​:wink:

hello, if you want to use the amazon epoxi make sure to try it on test samples. it is a completely different quality than we use for laminating. ( sniper said the same.) As I said, you are welcome to call me or just visit me. I will be happy to show you carbon parts from the last 10 years that I have built. I have had very good experiences with the RG brand so far. you can get in Austria from Lindinger modellbau. And HP textiles from Germany. You can order there directly. Both companies have very good instructions for laminating, coating, etc. online.

for the final finish I recommend 2 k car clear coat. 1 kg including hardener costs about 15-20 euros. you can paint 3-4 boards with it. You can also sand the 2 k lacquer to get perfect results. after the complete drying, you can then polish to a high gloss. this is not really good with 1 k spray cans or not at all because it is too soft.

@Sniper and @funboards.at

I not shaping ( at the moment ) a foilboard. I will use that year my prototype Mala Infltable.
So, i print a BOX in PLA with less% Infill and laminate theme wit CFK and Epoxy.
Same with my Akkubox, Mastclamps.

So, do you think i am still on the wrong way?

@Thomas, it can be nice to meet or speak about. Any help es welcome :slight_smile:

Okay, wich one i should buy, perhaps you can send me Links?
On the Website from Lindinger i see a lot of Epoxy, i dont know wich one is the right one.
I bought my CFK from PHP, i got informations from a guy, he also build a lot of PArts in the last years. He say to me that ist good. Also easy to work because it is “Rutschfest” :slight_smile:

if it s just for that youy can use it and test it i use the bad qualitee epoxy for internal box who don’t see water😉

No, i want to be sure that i got no problems with the water. So i decide not use that epoxy now.
