Time to do the casting What do we have Resin Catalyst Mould Mixing bowl Mixing device Raw polyester resin Catalyst added Mixed, note the darker tone now, its an effect of the mix forming chemical bonds changing the structure, some of you will know this as "curing" this is a 100/1 mix ratio, resin to catalyst, but i am rounding up to the nearest gram, in this case 170g resin needs 2g catalyst, i weighed the amounts out before i started to save myself some time Sorry no pics of the pouring, the fumes liberated by the pour can mess up fine lenzes Pouring done As this is a one part mould you are going to get sunken and risen areas due to surface tension, so you may want to spread the top surface outside the confined ot the moulds sides to break that for a true smooth finish, this only applies to one part moulds where you are filling fight up to the top surface ITS READYYYYYYY!!!!! When cured you will notice its changed to a rather green tone and has some lateral shrinkage You will also be able to make out some hairlike marks in the surface, this is part of the curing process, where 2 curing areas meet they form this boundry line just like a continent A few of the finished items, on a block of alu to help dissipate the heat, as the resin whilst curing can get up to 80c
All 4 parts cast, time to get the mouse sander out Here we see the mouse sander in its natural habitat, about to pounce on this basking bezel piece 10 mins and a lot of swearing later (sanded my finger) 30mins more and even more swearing (to annoy the neighbours) Ready to do the fine sanding ready to box up doe painting later
MEMO TO SELF...... Shout at Nzxt about the quality of there steel, an hour to make a 40cm cut. I dont rermember the discription for the Tempest EVO saying "made of adermantium"
Its door fabrication time, that means HERE COMES THE DREMEL yay!!!! First up, lets get this side taken apart Tabs off, lets pop the window out I will be using 1.5inch cutting discs from MNPCtech Measuring up the new window bezel and making sure my cut lines are marked well inside the cut.... CUTTING YAY Deburring Well that took ages lol, but the results are exactly what i need Next up, filling the acrylic for the window and starting the cut for the top mounting panel Unfortunately i couldnt get any shots of cutting the acrylic out as the dust was getting in my camera, co lets ump to filing and sanding the cut edge I will be using a rough sanding pad for this as i have a lot of material to remove Whoops Ahh there fixed, ther was never a huge chunk taken out of the edge... was there *swings hypnotists watch* In the next post... i start work on the top panel
Cheers dude!! Casting can vary from easiest thing in the world to the biggest nightmare you have ever had, this is a relatively simple cast of a simple shape. Anythign can be case in tons of finishes, stone, marble, bronze, smoked, you can suspend objects in the mixture even transparent or translucent Anybody who wants to know more just ask me
Busy week, children, fabrication, deliveries, the list goes on.... Finialy an update and i am delighted to say it is a sponsor
