The holes are finished, all 221 of them. Yes that's what I said, two hundred and twenty one holes in this Silo that is only 6 1/2" high by 2" in diameter.
I also have bonded on the roof's facia pieces. I am trying to get the roof to set in place without bonding, but it's not being very friendly in that regard. I need to do some reinforcing of the roof's surface also. I think I have gotten the cart before the horse in regards to the reinforcing the roof. I probably should have waited to put on the roof trusses, even though they did solve a problem at the time. Oh well, it will just take a little more patience to get it done.
You can see in this picture the spacers that I have placed in the corners. They help locate the roof because they actually touch the end wall of the structure. The other two blocks were placed to try and lock it in place to the last truss, but didn't work quite like I thought it might. :evil:



Here you can see some of the holes that have been punched (not drilled) the Silo's wall. I decided to throw in the x-acto knife for some visual reference.



And a back side view.



All in all, I am happy with the build, but there is one area that I am not satisfied with, the entrance door and window. I just my rip it out and do it over again. :twisted: This thing looks so neat, but not the door, so I think I will just "Bite The Bullet"

You are going to have to explain the 'punching' of holes in such a delicate structure Wayne. I'm agog with curiosity.

Bob, not really to sophisticated really, Just used a compass that happened to have a tapered point. I tried to find a numbered drill bit, but nobody carried one that small. Needed a number 74 or 78 size, or anything around that.

Once I noticed that the point was tapered, I just started poking holes in styrene until I could get the wire to go through easily, then set the compass point to that depth.

You can see in the picture where the one point is out quite a ways. I needed that where I have two wires going through the same hole (next to the Climbing Tower).

All I did was place the point where it needed to be, and with slight pressure began rotating the compass until I could feel the point coming through on the inside. (only poked myself three times out of 221 :shock: :shock: :shock:)

Really, this worked probably better than a drill bit would have. It was real easy to keep the hole exactly where I wanted it.

221 holes - that's an amazing number, Wayne. Did you do all the work in a few sittings :?: I don't think I would have the patience to punch more than a few at any one time :?

Tim, I don't think my eyes or fingers could have done that in one setting. It took three days at 2 hours per day to get them all in place. I had to install every ring, locate the holes, then remove the ring. Boring to say the least, but I can say with a smile, It's all done now!! :D :D :D

Wayne, your making great progress - your on the home straight now! All that attention to detail will come through in the final product.

Stunning Wayne and the X-Acto knife shows the scale of the silo to perfection.

How you ever managed to do such intricate stuff at that scale - I'll never know - I'm full of admiration for you.

Boy, do I hope your right Darren! Loosing the detail of the block would ruin the whole look of the silo.

My Dad (and Mom) are coming down from Indiana to visit for about 5 weeks. I intend to take advantage of having another modeler here during that time. Since my nemesis is painting, that's what we will be working on!

So I have just a few days to complete the actual modeling, cleaning up some of the details that I'm not happy with, ie.: Entrance door, and Roof fit, then the painting starts. :( :shock: :roll:

Thanks Petermac, but it's really not that difficult. It only takes patience and not hurrying to get a specific item done.

I just bought a lighted magnifying glass, which should really help with the tiny stuff. I have some ideas on how to do windows differently, which will have some very small details. I need to get this down pat before I start building the House!!!! It has tons of windows!

I am learning a lot about how to do things in very small sizes. I have made mistakes that, while they seemed to look right while doing them, did not afterwards.

I did not like what I had done with the entrance door's window, so I cut it out and redid it. Is this what I wanted, well not quite, but it's much better than what I had to begin with.

Here is a picture of what I had first done.


And here's is version Two.


I did not remove the door, just because I think I would have done too much damage to the whole structure in order to get it out. So I just cut out the window. I tried to reshape the windows opening, it helped, but ... well I'm afraid it's the best I can do without major surgery. It is definitely more proportional now, which helps.



The first version was done with the smallest styrene strips I could get my hands on, and no window at all. The second was done with white electrical tape on top of clear plastic. As you can see here, I taped the "window" down to the matt, and marked out the locations of the window mullions. I then cut very narrow slits off the electrical tape, leaving one end still attached. This way I could pick up the cut end with my fingers of one hand and then pick up the entire piece with the other. I then placed the tape over the pencil marks for alignment. Once all four pieces were in place, trim the ends, and this was the result.



I do feel better about the window, much better in fact than what I had originally. I'm sure I could do better, but I need to do better planning in the beginning on these small details. Live and Learn, that's life!!!

Wayne

PS: Here are the two projects together.

The exercise with the windows and white tape is an easy one in 4mm scale Wayne but in N a different ball game. It looks really good.

This build is amazing, to say you have never done this before is beyond me.I mean you have done such a marvelous and expert job one would think you are a professional. You aint are and just kidding us :shock: :D .
I just think it is so fascinating watching the progress and your attention to detail is brilliant, well done.

Wayne, I am sure that you will get into the painting as you did with the white tape for the door..once you get started there will be no looking back! As I have just started painting* I am also particularly interested with your learning experiences.

(*tried cleaning a new acrylic paint I had bought from my brush using solvent not realising I needed to use water - this was an interesting experience as the paint congealed in in the brush initially!!)

Gee Whiz! :oops: :oops: :oops:
Honestly Phill, I have never done this kind of thing before. I always felt I could do it, but just never sat down and tried. Whilst in high school, many moons ago, I built a one quarter scale ranch home out of balsa wood. That is the closest I have come to model building.

As far as the detail is concerned, I've always said "The last 10% makes the whole project". That goes for many things, not just scratchbuilding.

Wayne :D :D :D

Well get ready Darren, because I'm not afraid to post even my worst attempt. I think everyone can learn watching how not to do it!!!! :D :D :D


(*tried cleaning a new acrylic paint I had bought from my brush using solvent not realising I needed to use water - this was an interesting experience as the paint congealed in in the brush initially!!)


Your not alone in that regard. Many years ago, having just hired in to a company, I was told to wash off this green stuff on the side of a vehicle. It was PVA (polyvinyl alcohol, a release agent). I hit that stuff with everything I could find, Acetone, Toluene, Mineral spirits, nothing was working, then my "Boss" walked by and told me to use Water! :oops: :oops: :oops: [size=9]I'm sure he did it on purpose too!

Like I said that's how we learn!

Wayne

I have decided that I have a problem that needs fixing. When I pick up the Silo with the Structure attached, it flexes to much. This picture shows what happens, I have exaggerated it somewhat for the picture. this picture also shows my solution, but I will get to that in a minute.

I analyzed the structure and came up with a plan to solve the problem. Under the Climbing Tower is an open, but small channel. I will make a "Tongue" for lack of a better word, that will go up into the Climbing tower, as the tower is lowered into the structure.



I made the "Tongue" from a piece of the 7/16" diameter tube (scrap). This picture shows the "Tongue" sitting on a scale, which is sitting on the structure. I tried to line up the "Tongue" with it's mating surface, to help show it here. I added the collar to the "Tongue" to give more surface area for bonding support.



This shows the "Tongue" installed. I have added another reinforcement piece underneath to give 1/16" of bonding area for the "Tongue". That should be sufficient to keep it vertical, and hold the structure tight against the Silo while lifting it up. An added benefit, I have reinforced the roof trusses.



Now the Climbing Tower is being lowered down onto the "Tongue"



And finally, the Tower is completely in it's installed position. I can now pick up the Silo by the Structure and nothing flexes at all. :smile: While this did solve my problem, it was a compromise. I will no longer be able to disassemble the model once the rings are in place. The rings that go around the Climbing Tower go into the Silo, thus preventing the Climbing tower from being moved. Since the tower can't be moved, the Structure is now "Locked" onto the Silo. I guess everything is a give and take proposition!



My ace in the hole, if you will, is the Roof. I will now make it so that it will be removable. At least I will still be able to get inside and change a broken window after the kids leave! :roll: :roll: :roll:

Next ......Hint ....Soap and Water!!! :sad:

Wayne
