Andy-Roo Posted July 18, 2020 Author Share Posted July 18, 2020 (edited) Morning all. So, fitting the Ham into the VS... When I first offered the tranny up to the skid it seemed like a straight forward instal, until I realised that the motor would foul the rear chassis braces and the rear bulkhead of the cab. Hmmm 🤔 Luckily the skid on the VS can be mirrored, ie - motor forward. First install - no dice. Mirroring the skid was easy with just a small amount of disassembly 🙈 Now the motor will sit at the front. Perfect 👍 Fitting the motor this way did mean I had to lose the across the rails battery tray. Setting the mesh on the 48dp pinion is quite tricky with the Ham in place, so this really needs doing out of the truck. Not very user friendly, but once it’s set I shouldn’t need to remove it that often (assuming the gearing is right). With the whole assembly fitted I found there was some ‘flex’ which I wasn’t happy with. At first I thought it was the weight of the motor pulling on the Hams CF chassis, but then realised it was in fact just the tranny ‘rocking’ on a screw moulding on the skid. I already had the VS transmission spacer fitted but I had some others I’d got from Shapeways, so with the thinnest one fitted the Ham was lifted just enough to clear that pesky problem. So with a bit of effort it’s in and sitting low enough to clear the interior I think, although I may have to turn the motor so the wires are on the side. Time will tell on that score. I’ve started on the body next so I can see exactly what room I have for the ESC and battery, but more about that, next time.

DartmoorTrails Posted July 20, 2020 Share Posted July 20, 2020 I'd have presumed DLUX would be right up their in terms of quality. I've had knuckles off Eric before without any issues. possibly a one off issue. Good you got it working though, be interested to see (hear!) what it sounds like when all buttoned up;) Quote Link to comment Share on other sites More sharing options...

I’m not trying to knock Dlux, just saying it how I see it. I think the Ham is probably going to be whiny...which I may or may not find annoying 🤔 1 Quote Link to comment Share on other sites More sharing options...

Yes, that’s the down side of a lightweight, comp spec trans. But I need it sitting as low as possible for clearance of the interior, so a cover wouldn’t work. It’s fair to say this transmission saga has caused me a few headaches..and I’m sure it ain’t done with me yet 🤪 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Andy-Roo Posted July 25, 2020 Author Popular Post Share Posted July 25, 2020 Afternoon all! Time really hasn’t been on my side of late, so progress has been slow with the odd hour here and there for my tiny truck ‘fix’. It’s time to get that lovely Yota double cab fitted along with the interior so I can see if there’s actually enough room underneath for everything. I picked up a set of printed sliders off Shapeways, that included body mounts to fit a Mojave 2 door cab onto an SCX10.2 chassis -even though that’s not the body or chassis I’m using here, I felt there was a good chance I could make them work. As it turned out they didn’t need much butchering.. They only needed this strip cut off.. These are the body mounts that screw to the sliders. They can be used in several different positions to get the fit right. The front of the both sliders will need a slight trim, but overall they work a treat. Just needs a hole drilled either side for the second mounting point.. Rather than screwing the body to the mounts I’ll be using the ‘studded’ method and flex the body over the mounting screws. The length of the studs will need adjusting later down the line.. With the body now mounted I moved on to the cutting and gluing part of the assembly. Now, up to this point of the build things have been relatively straight forward - it’s just been a case of getting parts to work together, but this is where it starts to get interesting. This clearly isn’t gonna fit like this. Break out the saw! 🙈 I’ve never been good with math, so measure ten times and cut once. Hopefully! 🤪 Marking out a centre line.. The first cut is always the deepest.. Chop chop! These Tamiya saws are the nuts 👍 So far so good.. I’m as surprised as the next man that this fits! 😂 To be continued.. 6 Quote Link to comment Share on other sites More sharing options...
Badcrumble Posted July 25, 2020 Share Posted July 25, 2020 Great work! Totally agree on those Tamiya saws, mine were great on the JK. Hope you get some time soon for more progress 😀 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Andy-Roo Posted July 25, 2020 Author Popular Post Share Posted July 25, 2020 So, to pick up where I left off... Next up for the chop were the front grill and wheel arches - both these were causing clearance issues, or rather the 4.75 tyres were! First on the block.. As you can clearly see here...I can’t cut a straight line to save my life 🙈 So, fresh from my wonky grill cut I set about those lovely flared Yota arches. Out with the trusty Tamiya hand saw again.. One... And two.. With the grill and bulkhead taped/clamped into place I get my first real idea of how it’ll look.. Next I turned the motor so the wires clear in the interior. I quickly put the basic interior together, screwed it into place in the Yota and sat on top of the chassis....and it don’t fit! 🙈🤣 It ain’t by much, but still a fail.. So close! To get an idea of where I needed to cut a hole in the interior masked up the to of the Ham and bottom of the interior, and then dabbed some silver paint on the highest part of the Ham to highlight where I’d need to cut. Not very scientific but it worked. So out with that small Tamiya saw again.. Now the interior fits over the Ham but I’ve got a bloody big hole in my Yota.. After asking @stimpy what glue he used on his Yota I got myself some Model X and a pack of cheap paintbrush’s to apply it with.. I can get in a right old state using glue but this went surprisingly well! 😬 I used some Styrene to covet that hole in the seats - I have half an idea of a plan for the interior.. So that’s where I’m at with it right now - the body will need more trimming for tyre clearance but I’m pretty pleased with it overall. My next step with be finding homes for the battery and ESC and bringing it to life! But more about that, next time 👍 7 Quote Link to comment Share on other sites More sharing options...
Andy-Roo Posted August 12, 2020 Author Share Posted August 12, 2020 Morning folks! Sorry it’s been a while since the last update - life has been taking up most of my time of late, but I’ve been chipping away at it whenever possible. So, picking up where I left off....finding a home for the ESC. Plan A As I wasn’t planning on using the rear battery mount that came in the VS kit, I was hoping to mod part of it so the ESC could be housed there instead. On first mockup it looked like a winner, but when I tried fitting the body it was clear this position just wasn’t gonna work 👎 The rear battery tray mount.. This looked bob on for mounting the ESC.. Although the fan would cause hight issues.. I made a simple plate and removed the fan (I’d deal with heat issues as and when necessary) Looking good so far.. But when I fitted the body with the interior in place it was clear this wasn’t going to work without cutting another clearance hole in the interior. I did try lowering the mount with spacers but could only go so far without fouling the rear driveshaft.. But that still didn’t give me the space I needed.. It was at this point I realised I was barking up the wrong tree with this idea 👎 Plan B So now I’m looking at mounting the ESC on a slider, but they don’t really lend themselves to the new idea and I need make a platform to bridge the gap.. Not having the right thickness Acetal I glue two pieces together and then glue those into place on the slider.. Mounted in its new home.. Next up..fitting the Holmes v3 servo. This thing is a beast 💪 It’s slowly.....very slowly, coming together. Unknowingly, I’d actually mounted it in the winch position at this point 🙈 It was at this point that things went a bit sideways. I tried mounting the servo from underneath which caused some problems, like damaging the servo wires which then needed to be repaired Doh! 🤪 So over the next day or so I repaired the wires, ordered another servo horn with a higher profile and eventually got the servo fitted and the link geometry sorted so the steering worked as it should. Big thanks to @CarlC and @stimpy for their help with this! 👍 TBC.. 3 Quote Link to comment Share on other sites More sharing options...
Popular Post Andy-Roo Posted August 12, 2020 Author Popular Post Share Posted August 12, 2020 Next I moved onto wiring it all put while trying to keep everything neat and tidy. *note; I didn’t have any black cable ties at the time! I wasn’t sure how I’d sort this lot out though.. But I did hook it all up to see if it worked...half expecting the servo to go up in smoke...but it all worked and I took it on it’s first run around the garage and up the driveway! 👍 Getting the wiring tidy was a challenge.. Running the leads to the rear required some trimming of the rear brace.. But the leads needed covering somehow. The RC4WD diamond plate came in useful for this.. It’ll get painted and weathered when I get to the body work part of the build.. I ended up mounting the on/off button on the transmission because it’s easily accessible from underneath and out of harms way.. With the body on.. There’s a couple of small jobs that need doing before I get into the body work proper, but that’s where I’m up to. So until next time people 👍 4 Quote Link to comment Share on other sites More sharing options...

I’d have cut the on/off switch off and wired it permanently on, but being HW it has the program button incorporated so it has to stay, unfortunately. Cable ties are priceless 👍 1 Quote Link to comment Share on other sites More sharing options...

Popular Post Andy-Roo Posted September 13, 2020 Author Popular Post Share Posted September 13, 2020 Evening folks.. Sorry for the lack of updates on this, there has been some progress though - the chassis is completely finished and is now a runner! I did have to take a few steps back to get it done though. I thought it was at that point when stuck battery in it for test drive, just to make sure it was buttoned up...and found it sounded like an old black cab with star ship mileage on it! Something was very wrong so I started pulling it apart looking for the culprit. It turned out it was the Ham transmission. There’s slight fore and aft play in the output shaft which was causing two of the gears to clash 🤬 It pee’d me off so much I pulled it out and fitted a VP 3 gear transmission, that I happened to have in stock for a future project. The swap didn’t take long but while I was doing this I decided that the extension leads I’d previously fitted had to go too. I wasn’t happy with the plugs so I pulled out the electrics and used my new soldering iron to cut and shut the leads. No more extension plugs. I also used this opportunity to swap out the blue sleeving I’d fitted for nice subtle black. So at this point I was much more happy with the chassis but there was one big down side to going the 3 gear route....the Yota’s interior! I either cut a big hole in it so it fit over the transmission, or I just forgot about the interior. Cutting a big hole is probably what I’ll do but for now I’m moving on with body and I’ll circle back and tackle the “the big hole” at a later date. Anyway, here’s some pics.. Just missing the battery strap here but it’s essentially done ✅ Oh, did I mention the new wheels? 😁 I’d seen these Boom racing adjustable offset split rims (still with beadlock) a few months back but they weren’t in stock, but now they are and I pulled the trigger. I couldn’t resist taking it out for shakedown run (the body has only been sanded at the this point) I’m really happy with how it performed and I’m sure once the tyres/foams have had a chance to ‘bed in’ it should only get better. Am deep into the bodywork right now - which I’ve done a great job of making a mess of....but more about that, next time. 4 Quote Link to comment Share on other sites More sharing options...

Looking forward to seeing the work on the bodywork! It’s very disappointing, but I’m sure I’ll be able to sort the problem out with a shim or two. I’m hoping to use it in a lightweight, low CoG build that I’m planning 🤞 1 Quote Link to comment Share on other sites More sharing options...
