  1. I too looked at Speeduino and the thing that really bugged me about it was the insistence of using an Arduino... I'll clarify I don't dislike the Arduino project - it did a huge amount for promoting STEM / electronics amongst school children and hobbyists but it's main purpose and what it's done really well is to make it simple for hobbyists and school children to get something functional up and running, it achieved that by being simple and cheap and achieved quite a cult following as a consequence. Rather cleverly in my opinion then STMicroelectronics created the so called "blue-pill" which basically put a modern (ARM based) microprocessor into the same format as an Arduino and put in the effort of making it, literally in most cases, a drop in replacement for an Arduino. So you can use exactly the same code base and the same hardware - you just choose which Nucleo (their version of the Arduino boards) you have instead of an Arduino, hit upload and the magic happens behind the scenes. What this allows you to do is use off-the-shelf code and libraries that other people have written for Arduino which is incredibly popular on a more capable chipset so that when you need more grunt you already have it. For example I'll quite often build a proof of concept using a Nucleo board and throwing in a bunch of Arduino libraries if it's software I don't already have. Once the project really gets going then I'll sit down and refactor things into a decent code base if required. What really bugged me about the Speeduino project (admittedly when I looked at it several years ago) was that looking through the codebase I could find areas that they were obviously struggling for processing speed or space on the chip (because the AVR used by default is quite a weedy chip by modern standards) so they would optimise some quite substantial sections of the code with AVR specific assembly instructions. Now from having spent a decent amount of time writing very high performance code (and occasionally dropping down to assembly to improve things) with modern compilers you will generally struggle to better what they can chuck out. If they'd left it as plain old C then it would be trivial to port to a new platform. In my opinion when they were struggling for performance they should have re-evaluated their choice of processor... Anyway minor rant over - best get back to some potentially paying work...
  2. If you underestimated does that mean I overestimated . I knew we'd convince him to fit a lightweight V8 so I might be in with a chance yet...
  3. I guess it really depends on whether you want "off the shelf" tanks. If it were me I'd be putting the winch in place and then seeing about a custom tank. If that's not big enough then can always add the extra tanks as discussed. They just add more complexity with plumbing etc rather than just putting up with a slightly smaller tank.
  4. Guess it depends on what rating they are? Assuming you're talking about the dampers here rather than the springs (which are technically the shock absorbers on the suspension)... If they're designed for a heavy vehicle then they could give quite a jarring ride, the same as having stiff springs. I do remember seeing tables of vehicle corner weight vs. desirable spring rate for different applications. Now you've got some numbers we can start comparing them.
  5. If ever there was a red rag to a bull... This is Stephen we're talking about.
  6. I've got a set of new 110 rear springs going spare that were designed to go with the Boge unit so are very very soft indeed. Put them on the 110 and it promptly sat on its arse.
  7. Ooops - here I was thinking we were guessing the weight of the 1UZ...
  8. @henk what do you mean neat? Neat by unobtrusive so it retains the original appearance of the cross member or neat as in doesn't modify it so plugs in as Steve says? Personally I'd be looking to keep the winch hidden and not sticking out the back so my approach would be to mount the winch between the chassis rails even if that meant cutting bits out and reinforcing. When you say it's 6mm is that a C section style cross member ala Nige, myself and Black Sheep Offroad style? With a 110 if you were concerned about fuel tank capacity then you can get extended tanks that fit up in the wheel arch so a smaller main tank coupled with that could probably keep the original capacity. I don't know if there are any off-the-shelf smaller tanks available as bolt in. @Stellaghost would have made one quicker than I've taken the time to write this out... I'd say a plug in cradle is nice for occasional use but they're not the lightest of things to lump about plus you've got to store it and then you'll end up leaving it behind when you actually need it. Plus there's a bit of extra faff with the hydraulics having to bleed off the pressure to connect and disconnect it.
  9. You're really not reading the post are you . Last time I checked Anderson didn't make hydraulic connectors... But you can get hydraulic quick connects cheaper than big Anderson plugs.
  10. 210kg minus flywheel and adapter is my guess. With manifolds and ancillaries and wiring harness.
  11. Might be they do the same thing as we Welsh do. Tell everyone the weather here is awful and nobody wants to come disturb our peace and quiet
  12. Actually @JeffR what @FridgeFreezer has said reminded me... I've got most of this lot going spare Caveat is that I don't have any of the shelves left - it was waaay cheaper for me to buy this lot (60 bays I think) second hand from an old movie prop studio than it was to buy the half dozen or so bays new I actually wanted. They are the proper heavy duty Dexion racking (comfortably taking a couple of tonnes per shelf), bays were 24ft tall and ~1m deep I think (basically designed to take a euro pallet). You're welcome to help yourself to what you want free of charge if you collect as I doubt I'm going to use any more of it*. You could easily cut them down to half height and bolt them together and then bolt more over the top then do what @muddy suggests and find a place that overhauls lorries and buy some of the old curtain sides to put over the top. * unless I find some compatible shelves in which case I might keep a few.
  13. Well I know a few years ago (2020?) I bought a load of aluminium scaffold tubes and clamps for £2k, it's enough to do four 5 lifts on the side of our 12m tall, 20m wide west wall of the house. I suspect you'd have a lot of change for building a carport out of that stuff.
  14. I've vastly improved rear leg room with L322 rear seats. They just about fit in once the seat squabs are squashed a bit. Need a fair bit of fab work though as they need something to latch into. A 6ft tall person can sit in and still has headroom and plenty of leg room because the seats are way deeper than normal Defender seats. I only mounted them temporarily (permanently) without butchering the seat box. If I ever get a roundtuit I'd lower them a couple of inches but as the only things that go on there regularly are a 5 year old and three dogs it's largely irrelevant at the moment. Unfortunately don't have any decent pics of the backseats.
  15. Hmm, any chance of pinging over some dimensions of them? We need to start renovating the flat so they might come in handy...
  16. He only has a 2 foot cube of iridium lying about and he is trying to save some weight!
  17. It's getting a bit tidier now, honest... Figured out why the John Deere ride on I'm selling didn't fire up. Bad wiring (in me), had the lever for the mower deck engaged not disengaged so one of the dozen safeties was active. Just need a new steering rack to arrive for it and I can put the deck on it and deliver it to the people who are buying it. In the meantime it's moved sheds so that's freed up a bunch of space. My trouble is I like being able to work on projects inside because I can and up until yesterday we've had a shocking summer. Just the projects tend to be big so I like having free space inside to bring them inside.
  18. Sorry it's a bit late @roamingyak but I gave a mate in Guildford my 110's old 300Tdi Salisbury (disc braked) axle when I replaced it with a Wolf axle. He's not far from @Hybrid_From_Hell so perhaps the axle could be acquired, overhauled (and potentially trussed) by our resident diff expert and shipped out?
  19. Once you've made a "proper" adapter can you use that in a sand mould to pour more or do you have to make it slightly oversized to allow for shrinkage?
  20. If only we knew of someone who'd built a lifting roof for a lift...
  21. Got my wee Gaston Dufour mill up and running today off an 11kW static phase converter. Motor sounds happy enough on setting 5 of 8 at least with the spindle and slow traversing going. Try the fast traverse and it's not happy. There's an 28kVA gennie outside which can power it for bigger jobs but at least this means I don't have to fire that up for quick jobs.
  22. I'm assuming you're running MIG at the moment? If so can you flip over to stick? I can quite happily run my inverter TIG (which will do stick) off a 13A socket and burn through a 3.2mm rod at 125Aish which I've found to be plenty for 20mm plate. I am Ving the plate nice and deep though but that's standard practice on something that thick. Those joints have held up quite happily to a few tonnes on them (the headstock attachments for the JCB's pallet forks). More specific to that inverter but it'll run 200A off a 16A breaker which will handle a 4mm rod but I've never had the need to try it.
