  1. Perfectly Rob. It's called an autonomous stem cell transplant, where you donate the stem cells to yourself. (The other type is called an allogenic stem cell transplant when the donor cells come from someone who has good results on the tissue typing, preferrably 6/6). When I first went into remission in 2002, I was prepared for this procedure because the hematologist/oncologist was quite sure it was going to come back quickly so I had my stem cells harvested. After some high strength chemo, I also went in every day for an injection that would stimulate the growth of new stem cells in my bone marrow, which then begin circulating in the blood. (These can eventually turn into all sorts of different things - red/white blood cells, bone marrow, etc. Amazing.) Every day there was also a blood test checking for a protein that is a good marker of how many new stem cells are circulating. Once the protein reached a certain level it was time to harvest, a procedure called apherisis. To me, this was very similar to a dialysis machine - blood out of one arm, into the machine, and then back into the other arm. I went for apherisis for three days in a row, each session was maybe three hours. The centrifuge separates the stem cells which are collected in a bag, and once a bag is full I had to sign and date the bag since they were going to be stored. I thought the contents of the bag looked rather like tomato soup. The bags of stem cells are then irradiated to do everything possible to make sure there is nothing malignant in there - which is always a chance. The stem cells are then frozen, and I believe are good for ten years or so. They collected my brother's as well, since he was a perfect match on the tissue typing. His cells were considered for a last-resort effort. As it turned out, my remission lasted for 12 years, way beyond expectations, and we never used the cells. Transplanting the harvested cells back into the patient is as you describe, and it's quite nasty. The extra chemo and radiation are again necessary to make sure all malignant cells in the patient are gone - plus your current immune system has to be killed off. The transplant gives you a new one. The big risk is something called graft vs. host disease, kind of like organ rejection but much worse. The risk of this is MUCH higher if the stem cells come from someone else, this is why autonomous stem cell transplants are much preferred. It's a long recovery period after the transplant. It sounds like your friend is in good hands, and I wish her much success. She'll need courage to proceed, but she sounds like the type that will take the bull by the horn and get on with it. Please extend my best wishes to her. As for you modelling types, sorry for the off-topic conversation. Certainly it's good for Rob and myself to compare notes, whereby we both can learn something, but I like putting it out in the open so others may learn something that might be of benefit to them later on. Thanks. Cheers, Bill PS. Her ex-husband sounds like a real cad.
  2. Cheers, Bill
  3. Those seats are the definition of sweetness. Mind if I steal all of your ideas for a Future Hawk project? Cheers, Bill
  4. Great news on the new treatment regime for your friend, Rob. Do you recall what it is specifically? I like to stay up to date on what's happening around the world with new therapies, and since leukemia is closely related to my lymphoma it would be great to learn more about it. Great landscape photos! What a beautiful land. Cheers, Bill
  5. I think that was discussed during my build of Ginger Lacey's XIV RN135. Many photos of 17 Squadron SEAC Spit XIVs with those ports covered with red tape, even though we think the guns themselves weren't present. Cheers, Bill
  6. Sorry for the lack of progress mates. I've been suffering from the worst sinus infection I've ever had (literally have to breathe through my mouth most of the time). I haven't been getting much sleep - plus I've been trying to prepare for Noreastcon (IPMS Northeast United States Regional Convention) this weekend. Someone volunteered me to do a presentation on the joys of photoetch, which is quite a chore since I never use the stuff. But I can probably purloin enough stuff from the web to make it look respectable. Since I haven't been responding to the sinus treatments, I'll be having a CT scan of my head tomorrow. They suspect I have polyps in my sinuses or something. I had a dream about it the other night - "Well, we have some good news and some bad news. The good news is we've found nothing of consequence in your head. The bad news is we've found nothing of consequence in your head." That would explain a lot! Anyway, I feel rather lousy, and haven't had much time for modelling. The only progress on the 111B has been the construction of the front landing gear, and I hope I have the nose gear strut leaning forward at the right angle. Even if it's off a bit, I'll just add the red stripe on the nose gear doors to match. Cheers, Bill the Stuffed (Up) PS. My oncologist is having me do a PET scan, and if all looks well I can stop the chemo. Woo hoo! Those lymph nodes better be the right size on that scan...
  7. Sweet little kitbash! Excellent job, John. Cheers, Bill
  8. Thanks for that, Tommy. That should have been quite obvious to me! I've been playing around with the intakes, and now I wish I had taken the time to make them more "seamless." If I model the intake with the translating cowl forward, as it seems to have been when on the ground, a seam is going to be nicely visible through the gap. So, I either fix the seam or close the cowl. Guess I'll fix the seam. Cheers, Bill
  9. Following the diagrams at Tommy's website, I built a rudimentary mechanism for the aft main gear door. For variety, I used square styrene for the door actuator bellcrank, T-channel styrene for the brackets on the door that the bellcranks attach to, and round styrene rod for the door leading edge idler. Now, this is one of the things that is so great about modelling. I was not familiar with the term bellcrank before, at least not in connection with an aircraft landing gear door. I looked it up in an engineering dictionary, and now I've learned something new. At my age! Here is what I came up with: In addition to the mechanism, you'll notice that I've filled some nasty sink marks on the bottom of the landing gear cross-beam, and since 972 did not have the rotating glove slats, that area is also being filled in. When the aft main gear door is added, she looks like this: Fortunately, my lousy scratch building will be hidden underneath the door, and behind the main tyres. In real life, the door leading edge idlers were an interesting curved affair that went from leading edge of the door to an attachment point deep in the main gear bay on the sides near the rear bulkhead (I believe). They were curved in order to navigate within and around the complex nature of the landing gear components. I've only built the part that is visible underneath the fuselage. When I attached the main landing gear assembly to the rear of the bay, it seemed to me that it wasn't right for the F-111B. The cross-beam (which connects the two axles) when viewed from the side was essentially parallel to the bottom of the fuselage. I believe this was a change that was put in place after the prototypes - on 972, the cross-beam should look angled up at the front when viewed from the side. So, I shimmed a little bit until I was satisfied with it. If I can remember, I'll take a photo of it to show you what I mean. Cheers, Bill
  10. Hi Rob, I'll approach this from the other side - as you may know, I've been fighting a blood cancer (lymphoma) since 2002. I had a nice 12 year remission after the first go, but it came back (as they said it would) in early 2015. Back on the chemo, which I will finish up in July of this year. One of the lovely elixirs that they pump into my veins is made from the same stuff that mustard gas is made from. Nasty stuff. Strange how things that kill people can also save people. I know that throughout my "journey" I never wanted people to feel sorry for me. Everyone's different, of course, but I always wanted it out in the open, I wanted people to talk about it, heck, I even joke about it. I suppose this is my coping mechanism. When I was first diagnosed (stage IV at that), the wife and kids were crying, it was a bloody awful thing. And it put real fear in me - and I didn't like that one bit, so I did (and do) everything I can to make sure the fear doesn't come back. Keep positive, look forward, and do what needs to be done. Your friend may not feel this way, but I'm willing to bet she doesn't like the fear either. Do what you can to keep it away from her. For what it's worth... Cheers, Bill
  11. Nicely done! Cheers, Bill
  12. I love this picture of 151970 (the first prototype) because it shows many of the F-111B unique features. You can see the knife edge boat tail, the pointed "speed bumps," early open arresting hook design, translating cowl intake, IR pod on top of the vertical fin, boundary layer control (BLC) vents below the wing glove, and the early design of the aft main landing gear door which is the subject of today's post. On all of the other F-111 builds that are part of this Group Build, the aft main door is hinged at the fuselage, and hangs down in a perpendicular fashion from the underside of the aircraft when the gear was down. The F-111B prototypes used a different mechanism that resulted in the aft main gear door positioned parallel to the underside when the gear was down, as can be seen in the above photo. The door was a different shape as well, completely covering the aft portion of the bay, unlike the production versions which left a slot open. The aft main gear door supplied with the kit has two strakes moulded in: These are not present in the F-111B underside photos that I have, so I quickly sanded them off. If you compare the shape of the kit door with that in the photo, you'll see that we need to add some material to the door. I started with a strip of styrene card, and I'll build it up from here. You can also see in the above photo how the gear bay opening matches the shape of the door. This required adding two small triangular pieces of styrene to the rear corners of the bay: The door now covers the aft portion of the gear bay completely. Now, about the mechanism that deployed and retracted the aft door. Rather than try to explain it here, I will refer you to the man who wrote the book, @Tailspin Turtle, and his blog where the mechanism is covered in detail: (scroll down near the bottom) I'll have to scratch build something that resembles this mechanism, at least the portion that is visible outside of the gear bay. Fun stuff, huh? I love this part of modelling - searching out the information needed to build an accurate model, and learning the history of the aircraft along the way. Having someone like Tommy, who has done the primary research, participate here is fantastic. Thank you! 151972 had fixed glove slats, unlike the production F-111 airframes that featured rotating glove slats. The rotating gloves allowed the inboard portion of the wing slat to be longer, helping provide more low-speed lift. This kit has rotating gloves, so the wing slats are too long and need to be reduced at the inboard end. But that is the subject for another post! Cheers, Bill
  13. I always thought it odd that Hasegawa provided a slot in the inboard section of the wing to allow fully swept wings, but didn't include alternate parts for the side of the fuselage that the wing recedes into. And I don't think any aftermarket sets have appeared for this, at least none that I'm aware of. It's not a big modification on the part of the modeller, but still strange. I know the F-111 looks great with the slats and flaps down, but it just looks so sleek with the wings back. Cheers, Bill
  14. Canopy mask is available from Eduard (CX205) - I used it on my build. Very inexpensive considering the amount of time (and contributions to the curse jar) it saves. Cheers, Bill
  15. I think I agree with Peter. In the first photo (top left) of TZ138 in the collage, I don't think the left hand side of the outer circle of the roundel would be visible if it were recessed as much as shown on the Thai example. Cheers, Bill
