    As others have mentioned, adding diagonal braces will solve nearly all the wobble problems and you can remove all the center-connected vertical/horizontal struts as they’re redundant. Something like this should work: http://img229.imageshack.us/img229/3319/90312485wi2.jpg

    This is another decent design:

    As in the second picture, you can put that bottom center straight piece in there to provide additional rigidity. Usually it doesn’t affect your chair’s movement as it won’t go that far under the workbench anyway.

    For your hutch, just put some diagonals on the sides, and shorter corner braces (e.g. http://www.theenglishjoinerycompany.com/images/brackets/Gallows-Bracket.jpg) near the top so they’re out of the way.

    Basically, put diagonal braces wherever your structure suffers shearing.

    For the bench surface: consider buying some heavier material for the surface so that you don’t suffer as many vibrations and you could even drill/clamp into it. A plywood surface is sometimes a bit too thin. Solid wood is nice, and you can round off the corners somewhat. Also consider adding hard-points for heavier equipment such as bench vises.

    That H2OhNo! is a solid product offering, and represents the best of SparkFun: a small board incorporating a relatively exotic sensor, a programmable microcontroller, an LED and sound-emitting device, and even the means to power everything. All this for a reasonable price and support too. Keep it up guys!

    For myself, on Amazon I’ve purchased 6x for $13 shipped. Arrived in a week. No defects, looks and operates to the same spec as those sold here, etc. Even the single-unit, Prime-shipped coolant hoses run less than $6 each. The SF prices above are on par with the brand-name Snap Flow kits that Enco sells – the site the original Instructables guide links to (http://www.use-enco.com/CGI/INPDFF?PMPAGE=935&PMITEM=240-7509).

    The hoses are a commodity item, and on SF they’re simply not priced competitively, especially for no-name parts that probably come from the same Chinese warehouses. The plates, however, are the hard part of the project to find or build. The threads on the base are slightly tapered with a somewhat oddball ½"-20 threading. People don’t want to buy special tap kits or bits for that, only to have the tubes still not fit. I’m lucky enough to have a friend who has the facilities to do it right and he’s making me one with some scrap.

    I don’t know where you got the first stock of plates, but if you guys start shipping branded plates with part holder compartments, etc. you’ll corner the market on high-end third-hands. You could even anodize them with a sharp colored logo, or even just solid black for something really fancy.

    I’m sorry, but that price is way over the top. This isn’t even brand-name stuff. Start selling the plates alone so we can just buy the hoses elsewhere.

  • News - Free Shipping! | about 6 months ago

    Not to sound ungrateful, but I think this is a necessary change that was a long time coming. Given the premium price of many generic parts, and the larger availability of parts from competing vendors, you’ve gotta stay competitive. Shipping charges from Sparkfun have, in the past, made me seek out other vendors because I don’t want to be paying 1/3rd-1/6th the price of what I’m buying in additional shipping. It really adds up, and is especially amplified for smaller orders.

    I’d actually prefer the threshold reduced to $25 like Amazon does to encourage more impulsive purchases, but I realize you guys don’t have the same large distribution network to make it happen. Perhaps non-bulky goods could qualify for something like that. Still, at least with this change we can consolidate our orders to avoid getting dimed by the freight charges.

    No. That’s just a subjective generalization about quantity. It’s not related to assumptions about the proportions of quantities – which is what I was responding to.

  • Product PRT-12042 | about 6 months ago

    Your assumption is fundamentally flawed as well. The only data you have to go on are just the people who don’t read the datasheets (thoroughly) but are asking the questions, but nothing about the remaining population who don’t ask questions – possibly because they did read the datasheets.

    It’s like making conclusions about the outcome of an election based only on how many votes one candidate received, but without any other data such as total number of votes.

  • Product PRT-12042 | about 6 months ago

    You’re pulling that figure out of your ass. It’s probably a poor assumption considering the type of people who frequent this site/store, and a product with such an esoteric purpose.
