RE: Ford Escort MK2 1/5
Very nice Lars! This piece of drive train (the angled gears) is a neat idea, makes me think of a way to make a home made diff, if you cut the shaft in the middle and have an output on each side driving a universal. Would just need a small piece of tube around the cut center part to hold the two shafts aligned. I like how you engineered the rear suspension too, how you reused the plastic parts to integrate in your design. Keep it up! Fred

Custom made 1:10 RWD solid axle Escort MK2
Hi all, I recently got interested into doing a somewhat mechanically scale Ford Escort MK2, much ispired by member prestonlal own scale Escort MK2. He is doing awesome work on his, and as you will see I did use some of the same part as his build, namely the gearbox, the rear axle and Escort MK2 body from RetroRacing. Make sure you look at his thread over here if you have not already. Well technically it is JBLKING's thread as he was looking for a on-road RWD project, but it kind of drifted into prestonlal's own thread :) http://www.rcuniverse.com/forum/m_11281891/anchors_11305270/mpage_3/key_/anchor/tm.htm#11305270 Here some of the characteristics and guidelines of what I want to build: - Fully home made aluminium ladder type chassis - Solid axle rear end (Tamia CC-01 axle) - Four link rear suspension, with watts linkage - Macpherson front suspension, with similar operation as the actual Escort MK2 - Front mounted motor (Tamiya sport tuned black motor) - Realistic weight distribution, both for center of gravity height and fore-aft weight distribution (I would like it to handle like a real car, and not like an rc racing car) So I would like it to handle more like a full scale car than like the regular RC tend to handle with their very low center of gravity. It would be great if the car would roll, squat and dive a lot, and the best would be if it turns on three wheels like the real thing :) [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/7B97F37E-5D25-4F09-B342-26E8A0BAB395-216-00000030C951B446.jpg[/img] [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/7E2F3026-7126-4E9C-8B86-CD2C9B086411-937-0000010BA8691B95.jpg[/img] So I was looking at different axles, and it is very hard to find axles that would fit nicely on a 185mm wide body, and at the same time be somewhat scale looking. I looked at a few ones like this: [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/f96cc3b74e8dfbbea1a3fc43c914630d.jpg[/img] Most properly sized and scale looking axles were discontinued, the only option left was the CC-01 axle which fits perfectly, but I was not 100% sure about the diff casing being off-center, I would have liked it better centered like on real cars. Another option was SDI axles, whic are customizable in lenght with no special tools (thanks prestonlal for mentionning these). I had already pulled the trigger on a CC-01 axle when I finally realized I could have got a single SDI axle for 65 euros. fairly expensive but that would be very scale looking. I also liked having a real diff better, instead of the solid spool found in the SDI axles. I might change my mind once I ride the car and have traction issues :) http://sdi4x4.com/product_info.php?cPath=28&products_id=67 [img]http://i188.photobucket.com/albums/z286/sdi4x4/SDI%20AXLES%20EXPO/MIDDLEAXLE.jpg[/img] For wheels I already have some pretty scale looking steel rims looking wheels, and they fit nicely with the Tamiya Rally Blocks I already had from my TB-01 Rally. I plan on using these for the dirt rally mode on the escort, unless the offset does not work (they have a pretty high offset, not sure if it is +3 or +6. I found them on ebay but you can also find them at http://www.genkidoridori.com/index.php?manufacturers_id=48 [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/84824570-A716-4FE9-B763-B493750A6648-216-0000005CCDF3B9B0.jpg[/img] Not mine, but these are the same wheels and tires so it should look pretty scale: [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/18210b02139a0453cd5cab1d8f468ba7.jpg[/img] EDIT: I also have the same thread over at Scale4x4rc.org, I will likely always update both but here is the link: http://www.scale4x4rc.org/forums/showthread.php?p=966332#post966332

The wheels are a little too small and offset is not right. I thought the TB-01 wheels were 0mm offset so I bought +3mm offset wheels, end up being all sunk in the fenders. I added a couple small washers between the wheel and hex to adjust slightly (approx +1mm rear, +2mm front) [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/IMG_0894.jpg[/img] [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/IMG_0902.jpg[/img] Drift is kind of fun, I used to that with tape one the wheels (on my micro RS4) but when I saw the price of the drift tires and wheels combos I thought why not.

RE: Tamiya TB-01 Resource Thread!
I jumped the gun on a subaru wrc 2001 prototype NIB on ebay! I should receive it in a week or so. I am glad I found this thread, it is full of great info! This is my first post outside of the large scale subforum, so here is some background on me. I used to ride my nitro stampede about 13 years ago, then got a Kyosho mp6 couple years later, then micro rs4 when they came out, and I am currently building a 1/5 scale homemade impreza wrc based on the technokit body I scored on ebay (see the large scale forum custom builds) Since I have a world rally blue 2003 Impreza wrx I could not resist this one when I saw it on ebay. It says full ball bearing on the box, is that true or are there still some bushings here and there? [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/db0374ed.jpg[/img]

RE: the BIG one
Looking good! If the steering rod is also parallel to the A arms (when looking from the front of the car) you should not have any bumpsteer while the suspension moves. Well, if the 2 A arms are parallel, that is. If you decide to put your 2 A-arms not parallel (for instance to have progressive camber) then is is slightly more complicated. Not saying that you should make them not parallel, that's just for discussion sake :) Discussing suspension stuff is always kinda fun hahaha You might have already figured that out yourself but if you'd be having the A-arms not parallel, the optimal steering rod angle would depend on the height at which you mount the steering rod at the wheel. The lower it is, the more the angle should follow the lower A-Arm, and the higher it is the more the angle should follow the upper A-Arm. I guess a drawing is always better than trying to describe something in your second language :D [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/steeringarm.jpg[/img] [quote]ORIGINAL: Dirty_Vinylpusher The evolution of the A-arms.....

RE: fisher buggys light weight sanddrag 1/6
[quote]ORIGINAL: stiggwelder hi, it a volkswagon beetle gearbox which have the susp arm and drive shaft connected to the box by an internal cv joint, the wheel end has no cv joint and is fixed at a right angle to the wheel so thats why you get postive and negative camber at the wheels when the susp moves, its a good strong set up if you dont want alot of susp travel [/quote] Thanks for the info, so the CV joint is serving a dual purpose, driving the wheel while at the same time being the pivot point for the suspension, that's a cool setup! For your project, to find the best ball joint spots to ensure no binding at all you could draw a straight line (a small rope) between your 2 ball joints, and if the line passes in the center of the diff output drive then you are fine. Otherwise the drive shaft end might swing upwards/downwards as the suspension moves istead of staying aligned with the diff output drive. Fred

RE: buckshot racing X2R sand runner
Your projects make me want to learn to weld and get a tig welder and start to learn :) I don't know much about welding nor welders but I have been thinking about it for a while. Today I searched a bit about TIG, and I am wondering what is suite for this kind of small scale work (well large scale RC but small scale when it comes to welding!). Maybe you use the large ones because that is what you do for a living, if that is the case then what would you suggest for small projects, relatively good quality to be able to weld aluminium and relatively thin metal. Also if you know the price range it would be nice! Random google search suggest that welders like Miller Dynasty 200 SD is a good tig welder but I have no clue as if it is too large or not for hobby use. Sorry for being off topic but as you seem to use tig welder a lot I figured I could maybe ask ? Thanks and keep up the good work! Fred

RE: fisher buggys light weight sanddrag 1/6
Very nice frame!! I like the suspension setup too. Well the whole thing is cool! From the pics it looks like the drive shafts are going to be telescopic ? If so that's a good idea as I would imagine possible binding depending on the suspension arm rear mounting point location on the frame. I mean: mounting the arm higher (closer to drive shaft height) will help with binding but the suspension would not work well if mounted too high. (I have a small RC with a suspension that have the mounting point at the same height as the drive shaft and the suspension does not really work well, when you turn the suspension jacks up and the car want to climb over the wheel instead of compressing the suspension). Keep the pics coming!! Fred

The right pad is inside the disk, and is pushed towards the disc by the small cam shaft (light gray). So with a cable attached to the green area and pulling, the cam pushes the pad and squeeze the disc. Hope it helps! Fred

RE: Another large scale Impreza project
When I bought the lathe, there was a 4 jaw chuck included so I did'nt have to use Lars's trick with the tube, but it looks like it would work nicely. So basically I used a dial indicator to help center the square stock on the 4 jaw chuck (the 4 jaw chucks are not self centering, each jaw is individually ajdusted). Once I centered the square stock in the lathe, I started a small hole with a center drill at the right end of the aluminium square and put a dead center to hold it while I was machining it. I made the right end round on approx. 0.75 inch lenght so I could then flip it and hold it in a standard self centering 3 jaw chuck. I will keep this end machined round so it will be easier each time I will have to machine something out of this piece of 1/5x1/5 stock. With the lenght of stock I had (about 6 inches) I am pretty sure I could not machine it without the dead center holding the piece on the right side. I am not very experienced in machining, I'd have a question for the more experienced about tools. I tried to machine outside threads on an aluminium tube with a 60 degrees high speed steel tool but it did'nt give a nice smooth finish. With my carbide tools it's much better but the end of the bit is sligthly round so it does not looks like it is made for threading, right ? [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/LotImg3.jpg[/img] Is there carbide bits made for theading that I could screw on those tools? Those cut so much smoother.. Maybe it is because I grind the HSS bits with a bench grinder ? I have seen threading carbide tools on ebay but I think they are larger than what I need for my 1/4 inch shank tools, I don't know what to look for in size or part number. Fred

RE: New Project
I also thought about this issue for my project, I am still not sure how much of an issue it would be. Air being compressible, maybe 1 inch of air it would make enough space for the rod to take its space into the cylinder. If the shock is not sealed then it's another story as the oil might then leak with the pressure so you would have to have at least the same volume of extra space as the volume of rod going into the cylinder. In your case It would maybe be possible to weld tabs on the side of the shock body, allowing to mount the shocks at their side and leaving the top free for a flexible hose or attached reservoir. Back with my mspaint drawings :) [img]http://i194.photobucket.com/albums/z285/frederik_Bucket/dvp_shocks.png[/img] Edit: after posting I realized the reservoir in my picture is ridiculously small, would probably have to be larger :) In my case it's a little more complicated as I want the top shock mount to be swivel (ball) because of the macpherson design.
