      Here’s the thread I hope you’ve all been waiting for. I’ve had a good chance to evaluate the TDR The TDR 426- The Eval, Build and Superdetailing Experience 426 and I’ll be documenting the build and super-detailing for the new TDR The TDR 426- The Eval, Build and Superdetailing Experience 426 engine. Hopefully, this will serve as an instruction manual and a tutorial.

      [B][U]The Evaluation[/U][/B]
      First things first. Over all, I found this kit to be quite an excellent kit but it’s not for the rank beginner. I think at this point, the kit is ideal for the intermediate builder who has had some experience and success with aftermarket resin The TDR 426- The Eval, Build and Superdetailing Experience engines whether in large or small scale. With a minimum of instruction, though, which what this manual should provide, anyone should be able to handle the build with a minimum of problems and challenges.
      The biggest concern is the roughness of the surfaces. It wasn’t a major thing for the block since there you’ll want a sand The TDR 426- The Eval, Build and Superdetailing Experience cast finish but on some of the smooth parts, especially the thin ones, you’ll need to proceed with care. Still, the roughness should not be considered a deal breaker when you’re thinking of buying one of these beauties.
      Speaking of the thin parts, they can break very easily if you handle them roughly. When you sand The TDR 426- The Eval, Build and Superdetailing Experience them, go a bit slower. There’s no real rush and the result will be well worth the effort.
      The next concern is the fit of the parts. I was really happy to see these parts fit together so well. Even with some of the roughness on the mating surfaces, the parts went together extremely well. The fit reminded me of how a really great injection molded kit goes together. I don’t even feel you’ll need to worry much about adding filler.
      A third concern is the accuracy. To be totally honest, I’m not all that familiar with the correct measurements of the real thing but considering the folks who put the time and effort into this venture, I wouldn’t worry about accuracy. I’m sure that has all been addressed.
      Another great thing is that you can build this kit the way you want. There are plenty of options available. All you’ll need is a little planning.
      When all is said and done, I think this kit is a huge winner. IMHO, it’s better than a resin The TDR 426- The Eval, Build and Superdetailing Experience kit. The parts are light, accurate, well made and extremely consistent in thickness unlike resin The TDR 426- The Eval, Build and Superdetailing Experience castings. There’s absolutely no part shrinkage or warping. You will definitely need to put a little effort into the preparation, but no one ever said if you put the parts in a bag with some glue and paint and shake, a completed model will fall out. TDR The TDR 426- The Eval, Build and Superdetailing Experience , you done great. If you have any questions, don’t hesitate to ask.

    On behalf of of TDR The TDR 426- The Eval, Build and Superdetailing Experience , thanks for the honest evaluation Jeff, we appreaciate it. You mentioned that you weren't all that familiar with this particular engine or it's accuracy to scale.
    You're right, a great deal of care has been taken to keep it as close to scale and well detailed as possible. If you want to check it against your 1/6th R/M, Testors or GMP models you'll see what I mean.

    This material is going to be new to a lot of our builders so if I could impose on your good nature a bit, let's try to cover everything from tools, adhesives and types of paints used.
    I'm sure tips and tricks will be most welcome and hopefully we can save the guys some grief.

    I got my TDR The TDR 426- The Eval, Build and Superdetailing Experience 426 a couple of weeks ago and I also noted the thinness of some of the parts also. So I went back into the computer file and increased the thickness by about 30%. All engines in the future will have these new 30% thicker parts.

    Thickness is about only parameter of the parts that does not directly scale down and it is an issue that we always fight. If a part in the realworld is 1/8" thick it scales down to 1/64" which is about .015". The rapid prototype machince can make this but it is too fragile to work with. So TDR The TDR 426- The Eval, Build and Superdetailing Experience is always fighting that battle between proper scale dimensions on thickness and the practicality of working with the parts. If me make them too thick they look clunky and out of scale, too thin they break too easily.........

    That's already in the works, Don. As we speak, I'm working on the first installment of the tut that covers part preparation including the tools, methods, etc. I've already been able to polish some of the surfaces to a high shine but photographing them to show that is difficult. With a little extra effort, I've been able to get surfaces machined smooth. Covered with primer The TDR 426- The Eval, Build and Superdetailing Experience and paint, you'll never know what the raw product looked like. I should have stated it more clearly and I hope I don't offend anyone but this kit is not for someone who wants to build an engine in a few hours or is heavily into instant gratification. It doesn't require major modeling skills but it takes patience and care. This kit is for the modeler that wants the best in aftermarket parts and isn't turned off by the prospect of the extra effort. When you see the final results, you'll see what I mean.

    Right on Jeff, we knew that going in. However there is a bright note for the plug 'n play guys. There will be a resin The TDR 426- The Eval, Build and Superdetailing Experience version of the Offy and 426 coming along for those that don't feel they have the time or skill to properly finish the RP The TDR 426- The Eval, Build and Superdetailing Experience versions. They will require a lot less effort on the modelers part but as you mentioned , some compromises will have to be made to facilitate casting The TDR 426- The Eval, Build and Superdetailing Experience in resin The TDR 426- The Eval, Build and Superdetailing Experience .
    The surface texture of the RPs is a gremlin we are going to have to live with. Sure there are processes available that can produce a dead nut smooth kit but the cost would be way out of reach for most and that sucks. TDR The TDR 426- The Eval, Build and Superdetailing Experience will keep on pushing this envelope and do the best we can with what is available, we will never lose sight of the fact that in this day and age the average modeler needs to get the most bang for the buck possible.

    Jeff, here's a couple close-ups shots of a 426 crate engine.....click on 'em and note the texture on the block. As you can see, you don't need to sand The TDR 426- The Eval, Build and Superdetailing Experience the block and heads of the TDR The TDR 426- The Eval, Build and Superdetailing Experience 426 baby butt smooth. I would think you could get close to this appearance with a minimum of finishing effort.

    Ahhh.!! Perfect. That's where I have the block now. I'm going to try and prime the block today an see what it looks like. There's a lot of really fine dust from this material so everyone make sure you have a dust mask on and wash the parts well before you paint.

    You also can surface treat the SLA material with super glue to harden and maintain shape before sanding The TDR 426- The Eval, Build and Superdetailing Experience . I use to use the instant liquid stuff it forms a good workable "skin".

    That's a great tip Ken, thanks.

    Here's another that may come in handy with these builds.....
    I always have plenty of "dust" from cutting chunks resin The TDR 426- The Eval, Build and Superdetailing Experience . The dust from sawing only as it doesn't have the bits of sandpaper grit in it. I mix it with a little slowing setting CA and use it as surface filler, pinholes and small repairs. It sets quickly and can be sanded or drilled without having to wait for conventional fillers The TDR 426- The Eval, Build and Superdetailing Experience to dry. It's a stonger bond as well. As a plus it sands at close to the same rate as the surrounding material.

    [B][U]The Build[/U][/B]

    This is the second installment of the TDR The TDR 426- The Eval, Build and Superdetailing Experience 426 which will involve the building of this great kit. This is where we’re going to start the preparation of the parts. Photo #1 and #2 show the block as it comes out of the packing. It’s close to the sand The TDR 426- The Eval, Build and Superdetailing Experience cast finish we want but still a bit too rough. The other parts though well detailed come out exactly the same way but will ultimately need to be much smoother to look accurate. That we’ll get when we get to those parts.
    Starting with the block, we don’t want to completely eliminate the roughness as I said because we want that sand The TDR 426- The Eval, Build and Superdetailing Experience cast, mild pebbly finish. The best way to accomplish this is with a Dremel The TDR 426- The Eval, Build and Superdetailing Experience tool using a wire brush. Photo #3 shows three different types of brushes. Any one of them will work just fine. The brass brush is a bit softer than the steel ones but when you’re working in plastic, it really doesn’t matter. I would use no faster than medium speed on your Dremel The TDR 426- The Eval, Build and Superdetailing Experience for the broad, flat areas and slower for more control where you want to preserve the detail. The three don’ts are 1) you don’t want to take too much off the surface, 2) you don’t want the wire wheel to gouge the surface and 3) you definitely don’t want the heat from the tool to melt your plastic. Put the wheel at a 45 degree angle, Photo #4 and #5, depending on your tool choice, run the wheel before you touch the plastic and move the wheel parallel to the wheel shaft with brisk, light strokes over the entire surface. Don’t scrub away or you’ll risk getting an uneven surface. You’re actually using the sides of the bristles to knock down your surface. If you use the ends, you run the risk of gouging. Photo #6 shows the way the surface comes out. The more times you go over the surface, the less roughness you’ll wind up with. Just make sure you don’t overdo it. Another thing you can do to even out your sand The TDR 426- The Eval, Build and Superdetailing Experience cast finish is to use a wheel like in Photo#7. I bought this one in my LHS The TDR 426- The Eval, Build and Superdetailing Experience but you can make one by getting a hold of a Scotch-Brite pad, cutting out a circle of material and mounting it in a mandrel. You can save a few bucks that way. Photo #8 shows another instrument I found. It’s a very fine diamond bur that can get into some of the corners to knock down the roughness. They come in a number of sizes and shapes. With all this stuff I’ve been using, it’s been getting easier and easier to get the right finish on each area of the engine. From here, you wet sand The TDR 426- The Eval, Build and Superdetailing Experience as usual as you need it and prime. Make sure that you wash the parts well since the sanding The TDR 426- The Eval, Build and Superdetailing Experience dust is very fine and needs to be brushed out. With all this info under your belt, at least now you won’t be sanding The TDR 426- The Eval, Build and Superdetailing Experience until the next millennium. In the next installment, we’ll be starting the build itself by getting the heads on. In that segment, we’ll also be discussing some of the glue choices you’ll have. Catch you later.

    Hey there Jeff, you're doing a great job with this tute. The techniques you are using will be very useful to the guys attacking these 3-D printer parts.....thanks, big guy.

    As you know I'm working on version to be cast in resin The TDR 426- The Eval, Build and Superdetailing Experience for the guys that don't feel they have acquired the skills to finish the RP The TDR 426- The Eval, Build and Superdetailing Experience stuff but still would like to have a nicely detailed basic TDR The TDR 426- The Eval, Build and Superdetailing Experience 426. I figured I would tackle the most difficult to hand finish part first. The carb. I'm only doing one because of the time it takes to whittle it into a form that is suitable for casting The TDR 426- The Eval, Build and Superdetailing Experience , but thought it might be interesting to you.
    I've got a bit more clean up to do before it goes into rubber and it's in 2 pieces to cut down on undercutting issues. As far as tools go, sanding The TDR 426- The Eval, Build and Superdetailing Experience sticks, pin vice and small bit, homemade scrapers and burs on a flexible Dremel The TDR 426- The Eval, Build and Superdetailing Experience cable were all I used. No magnification, fillers The TDR 426- The Eval, Build and Superdetailing Experience etc. have been employed to get it to this point. The white finish makes it easier for me to see when I'm working. I wanted to have a little detail in the mouth of the carb for the guys that build them with open velocity stacks.

    That's going to help me quite a bit. Thanks for putting up all those pics. I have a few sharpened home made scrapers I'm fiddleing with to get into those really tight places where the rotary tools just won't do. The big secret working with this stuff is patience. If you try to rush this stuff, you're going to have a mess. Then again, TDR The TDR 426- The Eval, Build and Superdetailing Experience did not put a completion time on the model. For best results, you have to take the time you need, period.

    HFC - do you have a gallery of reference pictures for detailing? I have tried to search our gallery to no avail. I did find some 426 pics on the net that I would be glad to post if there is any interest but I was hoping there might be a gallery somewhere more specifically pointed to the model that is in work.
