Re: Round Top skis 19/20

What also helps is to glue a piece of waste wood outside of the abs/pu. Like this the topsheet and fibres dont kink down over the edge and resin gets sucked out more easily Another great tip. I use wood side walls anyway so either gluing extra on there or just making the side walls wider is a prett...

Re: Round Top skis 19/20

You created a resin trap. Topsheet folded over the side works good to keep resin trapped with vacuum One solution is to have the fibres still sticking out so the resin can flow along the fibres to get sucked out. Ahh, that makes sense. The last pair I pressed were on a friend pneumatic press so we ...

Re: Round Top skis 19/20

Yes, I had my skis in the press, then a sheet of perforated release film with the breather fabric on top. The breather fabric extended onto the table over the holes in the mold where the vacuum port is located. Oh well, I will pay more attention to the flatness of the top sheets when the initial vac...

Re: Round Top skis 19/20

Another flaw and lesson learned from my first pressing. The centre of each topsheet seems to be crowned. I assume this means that the vacuum was not pulling enough or I did not use my j-roller aggressively enough to really flatten the skis. The bases are (surprisingly) over all very flat but the top...

Re: Round Top skis 19/20

Thanks for the feedback, that is a really interesting idea! I suppose you have not experienced any issues with the tacks incorporated in the ski. Although I also assume you would have to create a small recess in the cores to account for the head of the tack. I will explore trying this in a future pr...

Re: Round Top skis 19/20

well, they are good from far but far from good 😁 I am sure they will ski just fine at least for this season. Even with all of the flaws in the ski it was good to get over my fear of messing up and just doing it. I did the lay up in the mold. It was pretty straightforward really. I had bent tip and t...

Re: Round Top skis 19/20

Darn it! I didn't even think about that which is causing me a little concern for their durability. However, I will get them tuned and mounted to see how they ski, they are my first pair made solo on my own set up so I certainly wasn't expecting a perfect pressing right off the bat (although secretly...

Re: Round Top skis 19/20

After a lot of procrastination and self doubt i finally sucked it up and pressed my first pair of skis on my own set up. While the skis didn't turn out 100% perfect I think for a first attempt on a new system all on my own i think it was a success and i learned a bunch of lessons along the way. 1. A...

Re: Round Top skis 19/20

things are moving along. I have drilled the holes in the vacuum table to pass the wires from the heat blanket out to the power source. I then caulked the heck out of the wires/holes so I hope that they will hold up to the vacuum for the hour it will take to press the skis. I have found a source for ...

Re: Round Top skis 19/20

side wall glue up went well and so I sent them through the thickness planer on my cradle. I might have to run them through again as the cores are ~11mm thick in the centre with the tips being ~3mm. Unfortunately the depth gauge on the planer is in inches with only 1/8" gradient between them. So...

Re: Round Top skis 19/20

Great morning of skiing and managed to get some more stuff done after lunch. So, one of the mistakes I made was cutting the thick core blank into two on my bandsaw. I guess I did not keep the block of wood as straight as I should have and one of the cores turned out a little too thin on one side. So...

Re: Round Top skis 19/20

My thoughts as well, which is why the first version of my controller has two different extension cords so each blanket has its own power. They will be plugged into outlets that are running on their own breakers. We will see how it goes. With the rain today I spent time in the shop trying to get the ...

Re: Round Top skis 19/20

Honestly, I don't know. I guess I would assume that it extends into the mat but since this is an Alibaba purchase it might be just at the edge. I will be working on the mold for the press this weekend and then take the leap and install the heat blanket that will be inside the vacuum. Once I have all...

Re: Round Top skis 19/20

Last night I was able to add the plug and receptor to the TC wires on one of my heat blankets to test out the controller. First attempt the temp on the PID started dropping...wired the TC incorrectly but that was quickly fixed. Second attempt and the heat blanket rapidly warmed up although the light...

Re: Round Top skis 19/20

I have finally finished the basic wiring of the control panel. The photo shows just one of the PIDs wired but they are both wired the same way with a separate extension cord. Next up is the dry run with the PID to make sure they are set correctly and that the TC and the heat pad works as hoped. Then...
