    Here is that tour of the Airfix factory if anyone cares to see it. I thought it was interesting. Jenesis Designs and Modelcraft is a very good scale modeling channel IMO and something not seen too often...a female scale model enthusiast.

    @shipman: I did check fit through limits of travel of the swingarm, but it's a matter of the chain being too short. I also laid the chain about the circumference of the molded chain piece and found it too short there as well. One way or the other, I will have a chain on the bike by tomorrow. 😄 I'm working to add a few links as I type this. From here on out, it shall be 3D printed chains for me. No more of these.

    @AJohnsonindeed I did have the same little short shot piece in the very same place. Wonder how this got past their quality control inspectors? I watched a video tour of their factory and they seemed good about inspecting the parts trees before boxing it all together.

    On second thought, there were two rear sprockets included, one large and one smaller one. The instructions called for use of the large one. Maybe the smaller of the two would fit without lengthening the chain? I grow weary of this.

    The drive chain saga continues: after all the bragging I did about how well Tamiya engineered the chain building jig, come to find out the chain is too short. 🤥 All is not lost, there are more links, rollers, and pins included. I can measure the distance between the axle location on the swingarm and the hub, multiply that times 2 and I should be long enough by adding those links to the chain. I'm debating whether to throw in the towel on the chain and just use the kit chain and sprockets which are molded as a single unit (the correct length). I've about had enough Tom-foolery with this chain.

    Seats of ease: being located at the bow, a sailor might need a seat belt in foul weather or else go flying off that seat like a slingshot. 😄

    A stunningly beautiful model, Yves. All your hard work is really impressive.

    This kit was first introduced a LONG time ago, sometime in the 70's I believe. The molds have a lot of mileage on them. I think you're doing a great job on this old kit. Keep up the good work.

    I am now at the stage where the ends of the chain are joined with a "master link". I kid you not, I have spent a couple of hours fiddling with that link this morning. So glad it's done now.

    Rob The primary weakness with the Tamiya photo etch chain are the problems associated with cutting the links from the photo etch fret after the chain is assembled. Even careful cutting loosens the holding power of the "clips" that attach to the pins. Tamiya recommends gluing each pin/clip contact point with a thread locker glue (CA is what I used). But then you are left with rough spots that need filing down and smoothed out where the links have been cut from the frets. I am not going to attempt smoothing them out. I am certain it will cause the chain to fall apart in various places due to the stress from filing. Too fragile. In retrospect, that resin printed chain looks like a charm. If I had it all to do over again I would buy the resin printed parts but since you already have the photo etch set, give it a try. You may be more successful than I and figure out a better way of handling the issues I described.

    That's a much more viable option for extra detail. Price is right, too.

    All the things we put our parents through when we were kids come back to us with our own kids. I came home one day to find live fish in my swimming pool. My son thought it would be great to be able to go fishing in our back yard. 🤣

    Thanks for all the suggestions. Dug deep and found a pair in my stash that got the job done. Not interested in trying this again anytime soon.

    I may need to try and grind or file down a set of tweezers to a much finer tip to see if that might work. Obviously not the set pictured, as they are ceramic-tipped. 😄

    After taking a couple of days off from modeling, I'm back to take up where I left off on this photo etch chain building dilemma. On the left side of the jig are links I cut from the photo etch fret using a XActo blade. It distorted the shape of the links which Tamiya suggests using "something" (not specific) to pinch the links to tighten them against the roller pins. As you can see from the photos, my precision tweezers are no match for this small work. Got to find something to pinch those links and tighten them. To the right of the cut links are links yet to be cut. I will attempt to do this with a micro cutoff wheel in my dremel. I tried using my Xuron photo etch cutting scissors but those mangle the links as well. I am definitely open to suggestions if you have one.

    Must be raining over the entire continent. Raining here in Florida today too. Glad I found your build and will follow.

    Awesome videos. Could not believe how quick that 2 cylinder 50cc bike ran. Never knew there was such a thing. Who was the test rider?

    It's odd seeing a racing engine like that in the first photo just lying in the grass. Would that be a maintenance photo taken during the course of a race? Great photos! Would have loved hearing that 5 cylinder 125cc engine rev up.

    Next steps with the chain construction involve cutting the links from the photo etch fret. Since the fret is stainless steel rather than brass, it's harder to cut. I typically use a scalpel blade for this but I found it takes too much pressure to cut through, therefore bending (slightly) the links out of shape. As the fit between the links and the pins is so precise and small, Tamiya recommends "pinching" each "c" clip together to tighten-retighten the fit to pin after cutting. I found this to be beyond my capability with the tools I have, much too small for any forceps I own. Next I am going to try cutting the links from the fret using a micro abrasion wheel on my dremel. Hopefully this will prevent the distortion of the c clips and negate the need to pinch them. If that doesn't work, I'm going to need to find a much smaller set of forceps to maybe even tweezers. I could see this task ruining a set of precision tweezers in the process as the tips of tweezers are not generally used as a pinching type of tool.

    You are right, those stock seats look great. I wonder what other aircraft might have used the same seats? I’ve saved my stock ones since I used aftermarket seats in my model. In retrospect, coulda’ shoulda’ saved the money and went stock.

    Cockpit looks awesome Andrew. About those tanks, is the fit issue where they join the wings or just with the tank halves themselves? Using aftermarket seats in my cockpit, I had a small amount of difficulty getting the front seat mounted to the floor with the rear instrument panel attached to it, but you probably will have no issues using the stock seats (which look very good by the way).

    After seeing the way Tamiya engineers designed the tools to assemble this small delicate chain, you and I both will agree they are genius. A photo etch plate of links are placed over the roller pins exposed in the preceding steps. Additional smaller sections of chain links are provided, shaped like “c” clips to snap in place over the links and pins that lock it all together. Two plastic tools are provided to hold these small sections in place while they are pulled down, locking them into position. Very ingenious and well engineered.
  23. CDW
    Next up the pins are placed inside each roller. You will note the pins have a specific shape on each end and can only slide into the rollers in one direction. A head on the end of each pin holds each link in place. After all pins are in place, a plastic molded cap is put in place that hold the pins in position. The jig is then flipped over so the bottom cap of the jig can be removed, exposing the opposite side of the roller pins.

    I noticed the chain kit comes with two different sizes of rear sprockets. I'm guessing maybe there were different size sprockets used on the real bike depending on the particular race event/track.
  25. CDW
    Break out the optivisor, it’s time to build the chain! The chain kit provides a plastic assembly jig. and a whole bunch of 1mm rollers the rollers are placed in each of the holes of the assembly jig then two sets of photo etched links are laid down more to come….
