先这样了，对于初学者，碎碎的便于理解

楼主，原地址给我，我也能翻译

楼主你的翻译果然够渣渣，6.8尺的翼展叫你翻成2.7寸，还好45磅和13尺两个数据叫我锁定了原贴。制作人名叫Lance Campbell，他的原帖地址http://www.mmrca.org/lance/sledframe.html。看不懂英语的可以看看热闹，想看翻译的可以等一等。

And now the problem.....or I should say the 3 problems. The major one is that when I started spraying Duratec primer over the PVA, it did not look right. It looked too 'wet' too quick. I had waited an hour, when the instructions said only 20-30 minutes was needed, but the bottom line was that even after an hour, it was still not dry. The primer mixed chemically with the PVA, causing the fogging you see, and making an edge to the mold next to the part look like crap. Secondly, taking the blocks all the way to the edge, means that they are not sealed, and that they could easily absorb water when washing the mold off. Lastly, when drilling through what would be 2 mold halves to install the bolts and wing nuts to clamp them together, making sure there are balsa blocks on both sides at the exact spot would not be easy either. Thankfully, the original came out of the first failed attempt just fine. Off to try again....
现在问题来了……或者我应该说是三个问题。最主要的是当我用Duratec primer在PVA上喷涂时，看起来不太对头。它看起来太湿，流的太快。使用说明说只需要20-30分钟固化，我却等了一个小时，而且最后可能还不止一个小时，漆还没有干。喷漆和PVA发生了化学反应，生成了你们看到的雾状表面，并且让磨具靠金工件的一条边看起来像坨屎。第二，木块非常靠边，意味着他们并没有被密封起来，这就让他们能在清洗模具时能轻易地吸收水分。最后，当钻通对半模具的螺栓和翼形螺母夹紧孔时，要确定该点两侧都有巴莎木也是不太容易。辛亏，第一次尝试失败，但原件还可以使用。偏一点再试一遍……

回归正轨

You can only do so much reading, research so many products, and talk to others about this process.  Eventually you have to do it yourself, and find out in a couple of days, if all of the chemicals and products   you've assembled will play nice with each other.  Last update you saw the ending result of a problem with the    PVA.  I've now changed my timing of my process, and found that all the chemicals I've gathered do work well,         if I let them have the proper time to cure and dry.
Success can be seen below and I now have my first set of usable molds!  2 years so far, and finally I've got my first molds.

I improved my balsa block idea a bit, and did not put them out on the flange.  That makes putting the bolts and wing nuts in, used to clamp the two mold halves together, easy. I can also put them where ever I want.   Secondly, it seals the edges easily, so that the molds can be washed, to remove the PVA after use.

第一段是说他很辛苦，很努力，发现只要让各种化学品有时间干燥稳定，就不会发生互相反应的现象。

第二段是说将要有自己的模具了他很高兴。

第三段是说模具夹持方法改进为四周，好布局，好取模。

It turns out that I, out of paranoia of hurting my original plug, put on my PVA a bit heavy, which means it takes a couple hours to fully dry out.  For now, my process will be, for example, shoot PVA before work,  say on a Friday morning.  Shoot my Duratec primer after work that Friday night.  Then be able to get up Saturday   and lay up the mold(s).  The molds you see below, of the outboard elevators, have 14 layers of resin and cloth    out on the flange, and 8 layers in the middle (4 below the blocks and 4 above), so you need a full day set         aside to get that many layers down properly.

这段是说他在制造时间上的控制，一天喷漆一天支模一天干燥一天扯布啥的。

Now that I'm getting the process down, I'll try doing more parts at once.  Next will be building the molds for both wing tips at the same time.

现在我已熟练这套流程，我会试着一次制造多个部件。下次就会同时制作双翼翼尖的模具。

[size=+1][size=+1]Wing Tip Molds Done

The wing tips are finally done, and they turned out great.  This process takes a lot of time, but I am just thrilled with the results so far.  Below are some shots of the progress of these two molds:

翼尖模具搞定

翼尖终于搞定了，它们看着很好。这个流程花了很多时间，但是结果让我激动。下面是一些模具的照片：

日，300K的图片都说太大，接下来我怎么搞？
