Inhouse post curing ready

Before starting new batch of planks I decided to build a post curing box. In fact it will support both curing and post curing. Elevated temperature lowers viscosity and improves  resin flow.

But the real benefit is that I no longer need to outsource post curing. Now all can be done inhouse.

The box can accomodate two planks 😉 and it will occupy big portion of my small shop floor ;( 

If you haven’t seen my plank movie yet this is the right moment to do so.

Boom jaws design 2021

Stop watching this post if you think plywood boom jaw works just fine for you. I agree, in most cases it does.

But this is a part of DN jewelery and this tiny but important detail has to look good too. And it does.

Aerodynamic sidestay adjuster

Covid kept me locked for 14 days. This is a side effect of having extra time. And this is not the only project I’ve beed working on 😉

At speeds greater than 100kmh aerodynamics start to play a role. This is my upgrade for sidestays adjuster. 3D modeled and printed shell accomodates standard adjuster. Vinyl carbon foil adds a great look.

And this is how it’s made:

Plank protective pads

This is must have for every plank. It protects the plank against spikes. And there are many ways to do it. Some use rubber, some use all sort of plastics. I like it to offer supreme protection and cool carbon look;)

To build my pads I use:

  • 2 layers of glass biax 300g/m2 +45/-45
  • 2 layers of carbon twill 200g/m2
  • Final width is 30cm.

The outer layer is peel ply. This will leave rough anti slippery surface once you peel it off. 

Notice small wood blocks hanging on both sides serving as weight to bend laminated edges for perfect fit. 

MMA adhesive. Of course!

This is how I press it and wait for adhesive to cure. Wooden block prevents middle part from being lifted as sides are compressed. 

DN Tech Talk | 04 vacuum bagging tips

The next DNTT04 is out! This time few tips and ideas for those of you, who would like to start or master vacuum bagging technology. 

All my planks since very beginning are made in vacuum infusion which is a level up process compared to vacuum bagging. Highest quality and consistent results are possible thanks to controlled process. 

However vacuum bagging is the best method to modify your plank. Vacuum helps to press wet layers of reinforcement and evacuate excess resin from your laminate if you try to stiffen the plank. This is a must know method if you think about modifying your plank bend characteristic.
