Lovely. Black is so sexy, and strangely enough it's also cheaper than clear or white for most of the materials.
1. If you have it is is worth it.
2. Nuts to hold together, or steps to hold them in. My town does not have .125 polycarb in stores.
3. I had to use the lathe to face all the plunger parts and stock rods, along with making centered holes and bringing down the OD of the 1in rod to fit with O-Rings. Mill to remove areas inside of parts, along with large hoels.
1. If you already have the aluminum, go ahead. If you don't want to have to try cutting a straight piece to make the plunger rod you can buy rectangular bars of plastic or aluminum at the desired thickness and width. I will eventually get around to trying UHMW Polyethylene for making the plunger rods. It should hold a thread well and be durable enough to make the plunger rod, but I want to try it first before recommending it since I KNOW polycarbonate works provided you drill the hole correctly. I will look into seeing if any other options for the plunger rod will make the partlist any cheaper.
2. The ONE hole you have to thread in the side plates lands at the centerline of the plunger tube so there's not really enough space to use a hex nut.
3. I mainly cut those parts using a table saw and I didn't have to face any of them. I did the cuts on one +Bow using a mitre saw and mitre box just to make sure it was possible. For the large diameter holes you need to drill it's best to use flat-blade wood-boring drill bits, which can be used with a mill or a drillpress. Changing the OD of the plunger core doesn't have to be done if you apply a TON of silicone lubricant to the plunger tube. If you do change the OD you better not shave off more than 10 thousands of an inch from the radius or you'll kill the seal.

The little critters of nature, they don't know that they're ugly. That's very funny, a fly marrying a bumble bee. I told you I'd shoot, but you didn't believe me. Why didn't you believe me?
