If the trouble with bonding aluminium is related to its smoothness there is a chemical treatment called alladyne that is used in the aircraft industry to help with paint bonding. It chemically etches the aluminium surface which I assume makes many many microscopic roughened areas that the paint can ...

Wood sidewalls on the bamboo core would definitely work. Good idea, thanks. Kingswood are across the ditch in new Zealand. He sources bamboo direct from china as he had early troubles with it being too dry or too wet. Now it's custom done for him. I've talked to a few wholesalers here who can get me...

Yeah 153 is good. I don't have any sidewall plastic trying to keep it simple. The floorboards are 160mm wide but the Tongue and groove rob 5ml on either side so I don't have the width to make that ski!
Free aluminium! I spent a day searching for scraps and cutting on the guillotine and drilling.

Getting started!

Hi Everyone. Thought I would start a log of my progress to look back on, especially when I feel like I'm not getting very far! Like most journals I firstly want to say thanks to everyone for their input and answers to often pretty elementary questions. The "I wouldn't be where I am without this site...

Those thermocouples come in a bag of 5. I think 35 dollars for all 5. The female connectors are 3 or 4 dollars I think. If you have that k type one with a bulky end you could use it just need to find a way to mount it in a meaningful place to read temp (maybe harder in a snowboard, in skis I think m...

Hi Nick I think with the help of these guys I have worked it out. The following picture is a bit confusing http://www.omega.com/Temperature/images/5LSC_5SRTC_l.jpg The 5SRTC type highlights the large yellow adaptor, which originally I thought was the thermocouple. However, this is actually just a me...

Aluminium isn't hard to get. Any commerical metal yard should be able to get it in many different thicknesses. Usually 4'x8' sheets. To get it easily you have to pay the going rate though and aluminium is relatively expensive. They should be able to cut it on their guillotine for you too in the shap...

Aluminium Cat track thickness

Hi Everyone I am getting ready to order some aluminium (that's Australian for aluminum!) for my cat track and wondering what thickness people use. I am looking at 3/4 inch (which for me ends up being 19mm). It is available in 1.6mm and 3.2 mm wall thickness. The man at the shop said to go with the t...

and no indentation on base of board (probably obviously not as otherwise you wouldn't do it like that)?
how thick aluminium are you using in your lower cassete layer?
thanks

Thanks mike
where do you place the TC probe in your layup. Between the blanket and cassette like doughboy?

you could look at getting thicker edge and base material if you are riding rails.

Triaxial Fibreglass, Australia

Hi I bought a bulk lot of triaxial 22 oz fibreglass recently. I have enough for about 50 pairs of skis which is a bit ambitious The roll is 49.2m long and has been sliced into thinner widths of 160mm. If anyone is building skis in Australia and is interested let me know and we can work out a price. ...

oh ok. So you have a female connector tojoin to the 2 prongs on the yellow coupler of the TC. This female coupler then has 2 wires coming out the other side that are screwed to the back of your PID?

OK. thanks for that. I clearly have a lot to learn about the thermocouples and PIDs. http://www.omega.com/Temperature/images/5LSC_5SRTC_l.jpg Sorry I am being a bit slow, but in the above picture are the exposed ends on the 5SRTC thermocouple what measure the temperature?
