Most of the specialized tools and equipment you need for snowboard construction has to be built by you. This tends to involve a bit of metal working and machining.

This page will expand over time to include more metal working resources specifically applicable to things like press construction.

== Working with copper tubing ==

The single best guide I’ve found for how to solder copper pipe is [http://www.copper.org/publications/pub_list/pdf/soldering_brazing_ads.pdf Soldering and Brazing Copper Tube and Fittings], directly from the Copper Development Association, Inc.

== To-do ==

Need to add links for the following topics:

* Drilling and tapping, including mag drills
* Cutting aluminum sheet for mold skins
* deburring
* extruded aluminum beams
* basics of precision machining
* cutting edge material

	I put the press on casters, and although the final weight with everything in it is right around 2,000lbs, it’s easy to move. Part numbers [http://www.mcmaster.com/#22955T42 22955T42] and [http://www.mcmaster.com/#22955T36 22955T36].

		+	I torque the frame bolts to 40ft lbs to ensure that all of the bolts are under pretty much equal tension once the press is pressurized. There is nothing scientific about the choice of torque, it is just something that felt reasonably tight using a normal crescent wrench. The only goal is that they are all the same.

	[[File:Press_BladderInputConnector.JPG\|thumb\|Press-to-bladder disconnect.]][[File:Press_UpperAirConnector.JPG\|thumb\|Shop air-to-press disconnect.]]There’s a quick connect on the input side that matches the rest of the air tools in the shop, so a standard shop air supply hooks up to the press. There’s also a similar quick connect from the press frame to the flexible hose for the bladders to allow the bladders to be removed when necessary. This also hooks directly to shop air, just in case.

-	All aluminum used for mold skins is 0.032” 5052-H32 aluminum that I get from [http://www.alaskancopper.com/ Alaskan Copper & Brass Company] here in Seattle.

	Each assembly is held together with a very simple system: 4 holes are drilled near the edges of the aluminum skins, two on each side, and the two sheets of aluminum with either a heat blanket or the laminate are held together with small lengths of 12awg copper wire, or with zip ties. You can see these poking out the sides in some of the pictures.
