I made my heat mats.b2therye wrote:I could use sicomin if i got a silicone vacuum bag.
did you make your heat blankets or buy them?
Also i'm finding it hard to source a bevelled router bit for the sidewalls...
which kinetix did you use falls? R104? was it any good?
I use a straight router bit in my laminate trimmer with a bevelled base plate to rout the sidewall bevel
My layup takes about 25 mins to get to 100°c and I leave it there for 10 mins then switch off the power till it cools to 80°c before I pull it out.
I got sick of wasting time watching the sestos controller cycle on and off, I also found it struggled to get over 90°c through the ssr.
What I do now is plug both mats straight into the wall and control the temps manually by switching them on and off. They sit at 100°c no problem, when it hits 101 I turn off the power, 2 mins later it hits 99 I flick the power on.
Its easier and works better that way

I say just do up the SSR and PID. It's nice to just turn it on and walk away. Before I had my PID straightened out I used to sit there and turn the physical switches on and off. That get's old real quick. Once I figured out the controller my temps don't go more then plus or mins 2 deg F and it's at temp within 10 minutes.
Kinetix R240.
Worked well in summer with higher temp. Easier wet out of fabrics and reliable cure. I had trouble in cold moist winter conditions to get a good cure. Ended up using heat blanket to keep it at 30c for 8 hours.
I have 2 blankets now. Both bought from America. Prob $1000 for the 2. There are a lot of Chinese companies on Ali baba that make silicone heat blankets for what seem like low prices. Never gave it a go but certainly could be an option at a lower price point. Any made in aus blankets I got quoted were pretty expensive even compared to shipping from MEI in the USA.

Don't wait up, I'm off to kill Summer....

Why not use an energy regulator? it basically switches on an off to regulate the heat (I work for a company who makes grills/toasters and ovens).
we use them all the time to regulate the heat of our toasters etc. i can send you one if you want goz.
i like the idea of using an epoxy that ski/snowboard specific.

Will they work on 100v? Ive only got about 9 boards to build before I move to Japan so if it wont work on the 100v jp power theres not much point sending one.b2therye wrote:Why not use an energy regulator? it basically switches on an off to regulate the heat (I work for a company who makes grills/toasters and ovens).

I appreciate the offer though mate ;-)
Those oven type switches sound like they are worth a try. Do you also have a digital temp display at work too? If so you might be set.
Im going to set my pid to on/off mode anyway. Variable duty cycle control of a relay is a waste of time, a relay is just an on/off so having your pid trying to bring it on at a controlled rate seems a waste to me. An ssr can switch pretty quick so I have set my variance to only 2 degrees. I'll let ya'll know how it goes.

Nah, this is a Energy Regulator, http://www.egoproducts.com/en/products/ ... egulators/chrismp wrote:You mean a thermostat? That's basically what a PID does, just with more adjustability and accuracy (which is required if you don't want any funky camber/rocker variations you didn't plan for).
We do have thermostats too if you want goz.
We don't have digital temperature displays but we do have analog ones
