RB5 2009 British GP winner Vettel

I found following deficiencies and inaccuracies in the kit. I mostly created this list to keep for myself, so I remember them and can decide, which ones I will fix.

- position of calipers is not horizontal, has to be corrected
- rear pull rods geometry is not very good
- pull rods should be attached to upper suspension arms at the position much closer to uprights
- drive shafts should end at lower location in uprights
- rear toe arms should be attached to uprights at lower points
- missing small cooling openings at the sides of cockpit
- missing gurney flaps on the floor at the sides of cockpit
- no representation of exhaust tips
- no slits in upper desk elements of front wing
- shape of the ends of upper desk elements on front wing to be corrected

While my F248 is waiting for new brakes and new polishing kit to arrive, and MP4/22 in different stages of preparation, I could not resist and started RB5 as soon as it arrived.

CNC Mill is back on-line

I'm finally back with CNC and machining. After 3 attempts and over 10 hours of trying I managed to adjust Z column on my Mill to some acceptable level. It may not be good enough for long CNC jobs, but is OK for small ones. Like making holes in brake disks and hubs.

Main motive to returning to machining is the need in new brake parts for my F248, MP4/22 and MP4/5B builds. Brake details in Fujimi and Studio27 kits aren't that good MP4/5B brakes will also benefit quite a bit from machined parts. Plan is to make disks with round vents first and then reposition rotary table horizontally, so square vents can be machined for F248 and F2007 brakes. Ferrari has being using brake rotors with square vents for quite a few years now.

It's great to have Mill back working after months of downtime.

S27 MP4/22 re-build

Parts, which needed to be glued before painting are in place and first layers of primer are on. Lots of sanding and puttying work ahead.

S27 MP4/22 re-build

Did test dry fit of parts. It looks kind of weird, but I didn't want to glue anything and used Tamiya's masking tape instead. Hearing a lot of things about bad fit of parts in multi-media kits, I was surprised on the fit in this kit. Of course continues test fitting is a must during the build process, but in my opinion fit is not bad at all. Fit on my modified Fujimi F248 build is actually worse. But in other hand F248 wasn't designed to be build the way I do it. Could not resist to make "family" photo. I like sophistication of modern F1 cars.

S27 MP4/22 re-build

More progress. Stripped paint from main body. Used same nasty lacquer tinner, but didn't submerge body into it. Instead used old toothbrush and cotton swabs to wet body with tinner and scrub old paint. Wouldn't left resin body submerged in this tinner for any period of time after few plastic parts melted in it after just few minutes.

S27 MP4/22 re-build

Stripped old paint from white metal parts. Used strong lacquer tinner from hardware store. Nasty stuff. I'm not sure what to use to strip old paint from resin body though. This thinner might destroy it, I'm afraid. Alcohol doesn't strip this paint, unfortunately. Will try to use lacquer tinner carefully.
