Honda RC211V, 2003, Valencia
To Page 2
This is the kit produced by Italeri. It is 1:6 scale, so BIG scale
This is a version of the RC211V I really like, and I thought "what a great scale to build this model in". Little did I know what was waiting for me when I opened the box.
As with a lot of larger scale kits of models that have been produced in smaller scales, there are not many parts, in fact there are less than in the Tamiya 1:12 scale kit.. This really disappoints me, but in another way really pleases me. It is because of "what pleased me" when I opened the box, I decided to write this as I build it. It just "BEGS" for detail!!!
To start with I will show you what comes in the kit..
I'm sure you have noticed that some parts are missing from the sprue's. That is because I started on it before I decided to do a W.I.P. of it. Most obvious are the Fairing (which I had already been working on) and front fork outer legs, (which I threw away).
I decided that not much of the kit was any good, maybe the wheels tires and decals would be the only parts I use. I still have not made a final decision on that yet. The kit is so wrong, and off scale any parts that I do use will have major modifications. It seems so easy, to me, for a company to make a kit to "Scale" when it is so big. I find it hard to believe it is a bad as it is.
I started with the front end,
the forks; after checking the ones in the kit for scale size, it was time to
discard all the fork parts and start from scratch..
I machined the slider from
Aluminum, with the idea of using stainless steel tube for the actual leg so it
would not scratch. I purchased a 1ft length of 5/16" OD stainless tube and
polished the outside. The aluminum part is machined to slide inside the tube
and then have a reduced section extending out with a threaded hole to accept a
2-56 screw on the top, and then be glued in position. Doing this allows me to
make the bottom of the leg separate and also slide it into the bottom of the
Then I started on the bottom of the leg. I could not find the correct square stock size I needed so I took some round bar, drilled a hole in it 0.180" deep, then milled a square. (Not quite sure why I'm doing this in aluminum though. ;) After completing the milling I made a radius on the end and drilled a hole in the side for the axle. Using a piece of a screwed up fork leg. (That's why drawings are important) Glued it in the top, along with a piece to fit inside the stainless slider, then finished shaping it so I can cast it in resin. Here is the part before I cast it It looks a lot better now.
To create the mold, I inserted two pieces of rod, 1 in each side of the axle hole (rather than drill it out and use one piece) the nice part about casting. :) Here is the mold I made and you can see where I trimmed it.
Now it's my time in the kitchen, I "bake" the mold in the oven for 5 minutes at 150F, remove it then pour the resin. Here it is with the "dummy axle" core and the finished casting 30 minutes later. I forgot to use a releasing agent on the core, so I had to chuck the part in the freezer for a few minutes and push it out on the drill press. That's it for now on the fork legs. I have to produce the drawings so that I get the Brake caliper mounts in the correct place. So I'm going back to the fairing for now.
The fairing came in four
pieces, but not the correct four pieces. The bottom section was split in two
pieces and the top was split down the middle.
The nose section sanded at the
kit seem before cutting it apart
These are the seem lines I want to cut through
As you can see this was not an easy undertaking with all the different
directions the seems go. Hence the blood loss.
I started the reworking of the fairing to include the "ram air" ductwork which is non existent. I used "Sculpey" to shape the duct on the inside of the fairing. I got it to a shape I was happy with, (a little oversize so I can finish shape it after it's cured) I realized I should have used some cling film under it, because it needs to be "baked" to cure, and that would have allowed me to remove it easily. Now if I try to remove it, it will change shape. Oh well! I'll just put it under a halogen lamp (thinking "I should have made a copy of these, no! it will be fine. I'll just keep an eye on it") Yup! you guessed it.........................................melted the fairing. Cured the sculpey though. ;)
It's not too bad although the picture does not really show how bad. Time to get out the Milliput. After a little while I managed to get the outside of the fairing back to shape. You can see the extent of the warping in this picture Looks a little like "Atom Heart Mother" (Pink Floyd, for those wondering.) I turned to the inside and worked the "Dremel" over it for a while and got it fairly reasonable for now That's the nice part about Milliput, it can be made very thin once cured, so it is great for repairs.
I reworked the nose section
with the ram air ducts in it and reassembled all the fairing parts to check
for fit using 000-120 x 1/8" long "binding head" screws. I will probably use
the next size up (00-90) for the finished item.
I tend to hop about a little
on this project. Now I have moved on to the Seat section, which will receive
similar treatment as the fairing. Remember this is how it comes in the kit
I need to make it a two piece section, but initially that will require me to
make it into five pieces., then into three pieces,, then ultimately two
I put it all
together with tiny dabs of Super Glue so I could work it in one piece,
thinking it would be easy to take apart when done. Once it was together I
sanded and shaped so there would be no uneven joints.
To start with I assemble the kit parts for the
support and remove the exhaust bracket and heat shield from the bottom.
Now it's time to get the Milliput out again to build up the seat support to
enable me to use the screws. I build up the base with a thin layer of Milliput,
and to ensure I get the correct shape, I use "cling film", which I wrap over
the top of the support then position the seat on top and squeeze into place. I
have to do this a few times to trim the excess Milliput until the seat sits
firmly on the matching edge of the seat support.
I fill in the small defects with Tamiya putty then will sand it all into a
nice smooth finish. For now I am going to fit the seat correctly then drill &
tap the holes for the 0-80 screws that will eventually hold the seat in place.
I have been trying to decide the order in which I will paint the seat, because the tail section requires two completely different colors and methods to achieve it. I think I will spray the insides with semi gloss Black first, then with the top lay down the white primer, followed by the yellow and clear coat and attach the Dzus fastener plates while the clear is still tacky.. The bottom with be painted gloss black and then the metallic color and clear coat the same way. But these are just thoughts right now. I'll cross that bridge when I come to it.
In the meantime I will make a new resin tank cover, and start work on the fuel tank and air-box.
I made a mold of the metal tank cover from the
kit, which has a pretty good outer shape so will work fine. This will be a one
piece mold. First I make the mold box from foam poster board.
Then prepare the tank cover adding some sculpey to the inside at the front.
The reason for this is to stop the rubber from flowing into the inside when
making the mold.
Then prep the box with used molds cut up and placed in the bottom to raise the
cover off the base to allow the mold rubber to flow around it.
I use Micro Mark's RTV rubber molding material. It is easy to use. Just
measure out even two cups of each solution then mix together. It sets at room
temperature. Before pouring it into the box I generally bang it on the counter
top a few times to make the trapped air escape.
(This is where I take time to answer emails and pack items to ship)
Four hours and a bit, later I'm happy with the result. Now it's time to mold the new tank cover. I want it hollow obviously and the easy way to do this is pour the resin mix in the mold then "swish" it around in the mold until it sets. Doing this I prefer to use "Alumilite" resin mix as it sets up in approximately 90 seconds, a little longer on thin parts. It will take 3 or 4 mixes to get the tank cover completed, here is the first wash. You can see the very thin shiny coating at the back of it. Obviously the thickness is inconsistent, but I will take care of that in another stage. Here it is after the last wash. Although the resin sets up quickly, it does not get really solid for a little while when its so thin, so I have to leave it for a while again. This is what I finished up with after carefully removing it from the mold. There was obviously an air bubble in the mold that I did not notice and while the resin heated during curing, expanded the air in the pocket and produced a dent in the top of the tank cover, but that is not a big deal. Overall its good, just need a little work removing the flash and with a Dremel to thin it down. The initial clean up just rough. It will take a few more visits to my Hi-Tech grinding booth and the Dremel to get it where I want. It is a little time consuming but what I finished up with is just fine. When grinding away at the inside to make it thinner, it is not necessary to worry about breaking through the surface. You can keep an eye on the thickness with a lamp; holding the part up to the lamp and see the light coming through. Kind of like X-ray, the darker sections are the thicker. If you do break through, just apply tape on the outside and dribble some epoxy on the inside.
This is getting long so, to
