I will gladly concede that drill bits are inaccurate. But that's not really the point here. Consider this scenario. I'm working on a project and decide, regardless of the hole size or accuracy required, that for whatever reason I want to use a #75 drill bit. I'm happily drilling away and manage to break the bit. So I go to the box where I keep my spares, open the packet of #75s and see there's only one left. "I'd better order some more," I think to myself. So I place the order and a week later, a packet of drills arrives. It's labeled #75 but when I measure them, I discover they are really #76s. As it happens, I already have a dozen #76s in the spare box. I don't need more #76s - I need more #75s. All I'm saying is, if I order #75s, I expect to get #75s. I don't want to have to order #74s and hope they are really #75s. A while back, I ordered some drills from MicroMark and one of them was actually 2 sizes smaller than what the package said they were. If I were to order a pair of pants with a 36" waist and the company sent pants with a 34" waist, I'd be a bit disappointed!    I might be able to squeeze into a 35" waist but I wouldn't wear them to a big dinner. 34" waist - no way.

I am sad to report that I received the drills from Drills America last nite and measured them. Every one is undersized. No better than the less expensive drills I bought from Drills and Cutters. I began to get suspicious of my measuring tools and techniques, so I took a piece of .020 brass rod and a piece of .028 brass rod from brand new, unopened packages and measured them with both the drill gauge and digital calipers. They measured the exact size. So it's not me or my tools. I contacted Mr. DeWitt and his reply was:
 
"John, I have no argument with you because the customer is always right. It's just one of those unexplained phenomena like Stonehenge, the statues of Easter Island or Donald Trump. Please return the drills at your convenience and we will refund all your money. Thank you for giving us a try and best of luck in the future."   So, indeed, I will be returning the drills. I guess I'll just go back to Drills and Cutters because they are less expensive and order drills that are labeled as one size larger than I need in hopes that I'll get some that are right. Very disappointing.

I don't typically use a pin vise - more likely a drill press for precise work. But, let's say you want to put a piece of .025 brass rod into a piece of sheet brass and you plan to silver solder it. When you silver solder, the parts need to touch to get a good solder joint (in this case, all the way around the rod). So, if you choose a #71 drill, the hole may be too large (.026) and you'll wind up with a weak joint. If you choose a #73 drill, the hole will be too small (.024) and the rod won't go into the hole at all. Your best choice is a #72 drill (.025), which is just the right size.
 
Of course, if you're putting a piece of brass rod into a piece of wood and you're planning to epoxy it in place, then, yes, such precision is unneeded.And, in fact, you'd want a hole that's larger than the rod to allow room for the glue. If you want to use thin CA to glue in that rod, you'll want a snug fit since thin CA doesn't fill gaps (kind of like silver solder).
 
But, again, no matter what the number on the drill or the application for the hole it will produce, when you decide you need to order a particular size drill, you want to know that you're going to get the size you order.

In the area where it says "Narrow Your Selection" find the size you want in the "Size (diameter) pull down. You'll see all the numbered drills listed there.

Just wanted to add that if you go to Drills America's website (the real one) the pricing is a bit confusing. In the description of each drill, it says "Package Qty.: 12" and the price is listed as, for example, $2.72 for a #72 drill. That price is for EACH drill and they only sell the small drills in packs of 12. So if you order 1, you will be ordering a single drill and it will show the price as $2.72 in your cart, but I'm not sure the order would go through since they don't sell less than 12. I mentioned this to Mr. DeWitt and he agreed it needs to be changed. In any case, I just told him what drills I wanted over the phone, gave him my CC number, and he put the order together for me. He also told me he opened each package that I ordered and mic'd one drill from each and they were spot on for sizing. So, a very helpful guy. Wholesale price on the #72s was $1.31 each, by the way. So if you call to order, be sure to mention the forum and ask for the wholesale price.

I just had a phone conversation with Michael DeWitt, who is president of Drill America - https://www.drillamerica.com/
It turns out that the owners of Drills and Cutters are cousins who split from his business about 15 years ago. They have created their own packages for drills that they obtain from China. The packages are similar to but different than the real thing from Drill America, who gets their drills from Precision Twist Drill in Crystal Lake, Illinois. His business is a small one and short of bringing an expensive lawsuit, he is unable to stop Drills and Cutters from their deceptive practices. His prices are certainly more expensive, but he guarantees they are American made and accurately sized. His primary business is wholesale but they do a small amount of retail business through their web site. Michael offered to sell me the bits I need at wholesale prices, which I thought was very nice of him indeed. He said if anyone on the forum called, he'd do the same for them.
 
Be aware that there is also a drillamerica.net website, which is also fake. The drills they sell are not produced by Drill America or made in the US.

I've had bad luck finding inexpensive numbered drills that are accurately sized. I recently ordered some from an online company called Drills & Cutters. Every one of them was undersized. For example, all the drills in the package of #71s were actually #72s (.025 instead of .026). I'd ordered 6 different sizes and all exhibited the same problem. The drills, by the way, are actually made by Drill America, which has their own website. I contacted Drills & Cutters about the problem and they sent replacements without charge and didn't ask for the bad ones back. Sadly, the replacements were just the same - every one undersized. I suppose you could take a chance and order one size larger of each to maybe get what you need, but I've asked for a full refund and intend to send them all back. I just don't want to deal with them any more. I'd ordered some from MicroMark as well before that and saw the same issue - some were even two sizes smaller than they should have been. Of course, companies like MSC Direct and Harvey's have drills that are probably accurately sized, but the price! Geez - around $10 apiece. That's a bit much for my pocket book. The ones from Drills & Cutters were all under $1 apiece. I guess you get what you pay for.

I wanted to report back that thanks to Frank's suggestion to paint on the product instead of immersing the parts, it works! I don't know why it makes a difference, but it most certainly does. I looks very much like Casey's. I tried a freshly-cleaned piece (sanded and wire brushed) and another cleaned piece that I'd soaked in vinegar for 10 minutes. Both look pretty much the same to me. On the uncleaned side, the one soaked in vinegar did darken a bit but it was still kind of splotchy. On the one that was not soaked, it didn't do much at all to the uncleaned side. So as with any brass blackening solution, thorough cleaning is a must.
 
Just for grins, I tried it on a piece of pot metal (some cast metal fitting in the scrap box) and solder. Both blackened perfectly. One thing to be sure of is that the solder is clean. I had some badly oxidized Stay-Brite (which doesn't, in fact, stay bright, by the way) and where it was oxidized, the blackener had no effect but on the bit that I filed clean, it turned black as night.
 
I tried one other experiment. I inserted a small-diameter brass rod in some basswood, which I sanded flush so just the end  of the rod was showing. I've done this sort of thing to simulate iron nails in the past. Back then, I used gun bluing on steel wire because the gun blue was clear and wouldn't stain the wood. But Casey's Brass Black is blue and will stain the wood. I dabbed a bit of the Jax on the brass and it turned black right away. There is no visible discoloration of the wood itself. The only thing with that technique is I don't see a good way to flush it with water without raising the grain on the wood. So there could be problems with the brass over time. I just can't say.
 
Anyway - again - thanks to Frank for the suggestion. I'm very happy that it worked!

When you're putting a false deck on a plank-on-bulkhead (POB) model, you need to be aware of multiple curves and angles and the way the bulkheads fit to the keel piece. I can't tell for sure on this model from the photo, but on most ships, the deck curves from side to side (that is, it is higher in the center than at the edges) and it also curves from fore to aft. When you sand the tops of the bulkheads in preparation for attaching the false deck, you need to make sure you are aware of these curves. The illustration below may help visualize this:
 
Note how the top of the bulkhead (in the side view) is angled to match the angle of the keel piece. (The sides will eventually be angled as well when you prepare the hull for planking. That process is called "fairing" the hull. It is necessary so that the planks will lie flat on the edges of the bulkheads.) As you sand the angle on top of the bulkheads, you want to be aware of the side-to-side curve as well - you want to maintain that curve - not sand it away. Try using a small block of wood (maybe 1-inch by 3-inches) with sandpaper glued on to it to sand the tops of the bulkheads. Take your time and once you think you have it right, put the model down and go do something else until the next day. Then come back and look at it again and you're almost guaranteed to see something that could be improved. As with a house, you are building the foundation of the ship. If the foundation is bad, you'll have more problems down the road, so it's best to get it right in the first place.

justsayrow - definitely not brass plated. It's a piece of K&S brass strip.
 
Frank - I did not try painting it on with a brush. I'll give it a try tonite - thanks for the suggestion.
 
I've written to Jax directly to see if they have any suggestions as well. I'm hoping I'll hear something today.

Well, I didn't realize Jax made a brass black as well as a pewter black. Somehow I got it in my head that pewter black was the right product. And, of course, their label comfirms that it is supposed to work on brass and many other metals. I did not try distilled water, so there could be something in my well water that causes it not to work although the instructions on the label say nothing about diluting the product and my results with the full-strength product were just as bad. I guess I'll be sticking with Casey's. I'm not going to spend another $25 to get a bottle of brass black.
 
Thanks to all for the thoughts and ideas.

After looking at both kits online, I'd go for the Pinta. It is overall a simpler ship and the rigging, especially, would be easier than the Halifax. And, as others have suggested, start a build log so you can ask for help when  you need it.

I have any number of Dremel tools including the one pictured immediately above. They each have their benefits. There are two things that bother me about the 8050 - the speed always resets to the middle value when you turn it off, (which is too fast for my needs) and while the lights seem like they would be useful, if you have the drill pointing towards you, they make it hard to see what you're doing because they shine in your eyes. I had to cover mine with tape.
 
I used to have one called the MiniMite, which was my go-to drill until the batteries died. I replaced it with a model 7000, which uses four AA batteries. I have a couple of sets of Eneloop batteries that I use with it. Eneloops are great because they hold a charge for a long time when they aren't being used. The 7000 is smaller than the 8050. It has just two speeds, which are normally all I need, and no annoying lights.

Just wanted to report back. I decided that .6mm was too small for my project but 1mm and 1.6mm would work well. I ordered a set of UNM miniature taps & dies from Amazon and some nuts from Scale Hardware. Using the 1.6mm die wasn't hard but the 1mm die was pretty tricky. Teeny, tiny! One thing I determined is that using half-hard, non-annealed brass rod seems to be the way to go. I bought some silver-plated copper wire (18 guage) and it turned out to be too soft - it twisted as I tried to turn the die and eventually broke off before I could finish threading. I also tried annealing the 1.6mm brass rod and it too twisted as I turned the die. So using the brass rod just the way it comes from K&S seems to provide the best results.
 
When I ordered the nuts, I made a mistake and ordered stainless steel 1mm nuts instead of brass. Didn't really matter since I planned to paint the finished assembly anyway. But the 1mm nuts seem smaller proportionally, than the 1.6mm nuts. In other words, I wish the outside dimension as a little larger. Nevertheless, they worked on the threads I created.
 
Here's a picture of the final assembly. This is a main sheet horse for the scow schooner Alma. The rod in the front is the 1.6mm rod. The one in the back is the 1mm rod. It does have the 1mm nuts on it but, as you can see, they look small compared to the 1.6mm nuts. Still, I'm happy with the results.
