I then spent 30 minutes giving it some test runs up and down the road. Things to think about. The steering is very twitchy. I need to check the toe as I think the tracking is out, but it is cough and you go off the road type twitchy at the moment. The button throttle is very digitial. What I hadnt realised is when you lift off the controller sticks a load of reluctance into the circuit and it braked quite significantly. The brake is almost not needed. The brake needs stripped and re-built. No matter how hard I pull the brake barely funcitons. It was a source of much amusement for my neighbours seeing me driving about in it, and a passer by in a car nearly veered off the road as they went past a little postman pat van. Either that or the sun was shining off the aluminium and blinding them . I took a few pics of the van as I had it out P1050759 by jono_misfit, on Flickr P1050760 by jono_misfit, on Flickr P1050761 by jono_misfit, on Flickr P1050762 by jono_misfit, on Flickr P1050763 by jono_misfit, on Flickr P1050764 by jono_misfit, on Flickr P1050765 by jono_misfit, on Flickr i then spent the rest of the session writting a list of whats needed, and trying out some body mounts.

What? Test runs with no video? How very dare you! Great progress

I tried, but it was a struggle holding the phone and controlling it all. I may look at a mount next time and try recording it.

I tried the same thing trying to video me driving our off-road buggy, all very shaky. A camera mount would be a good thing. I was interested to hear your comment about the twitchy steering and we had the same thing with ours. These things must be lethal on the road at 8mph particularly in a crosswind. I'm 99% sure that the problem is that there is no caster angle, certainly the case with ours and that's something we are going to address when we revamp the steering to fit the rack. I was actually quite surprised about this omission because a lot of engineering has been put in by the manufacturers to produce a decent suspension system with adjustable dampers etc. We'll aim for about 5 degrees caster and hope that will sort it out.

I'm not sure about if its caster angle or not on mine. The front suspension is swing arm hinged in the centre of the chassis (see post 1 on the thread), so the second there is weight on the chassis and the suspension compresses you are into a few degrees caster. This increases as the suspension swings through its arc. I'm going to have a look at the toe as if this was a car i'd say its on heavy toe out. Its also very quick steering which probably doesnt help with the sensitivity. Its ok when you have wide handle bars directly above it, but a small steering wheel (or yoke in my case) will make it feel even faster. its like turning a bike by placing your hands close to the stem on the fork, v's the grips. Bikes feel very twitchy if you do that.

When I built this I built the front end with neutral caster (ie none) because I knew nothing about it and it's effect on steering. What I found on the test drives was two things, there was no "self centring" effect on the steering ie after turning you had the straighten the wheel or you kept going round and it was extremely twitchy, slightest movement of the wheel could set off a virtually uncontrollable oscillation on the steering. Eventually discovered this was due to lack of positive caster. I introduced it by shimming the front beam the wheels etc are mounted on. What I discovered was as I increased the the positive caster, the twitchyness disappeared and the self centring effect increased (as did the steering effort, it got harder to turn). I just played with the shimming until I was happy with the steering, bearing in mind my son ( age 4 at the time ) was going to be driving. It turned out really well and the Jeep is easy to drive and the steering is stable at all speeds, the max speed ever recorded on it was 15mph, I had aimed (and geared for 10mph max) but a long downhill path with a 5 year old driving with his foot hard to the floor proved otherwise.

Bikes feel very twitchy if you do that. Our front suspension is identical to yours and with the original weight of the scooter plus a lardy driver will compress the springs and produce some caster but the thing we've found is that with everything removed and a lightweight driver, the springs don't compress at all resulting in no caster and a feeling of instability. I agree that the quick steering doesn't help. So what we're going to do is to drop the suspension pivot point so that with no spring deflection there will be some caster and hopefully self-centring and a feeling of control. Should the caster increase due to spring deflection I don't think that will be a bad thing.

Ive been busy with work, it was my birthday, and i'm also doing a load of DIY so progress is a bit limited at the moment. Still I did a few bits this afternoon. The main bit I need to do next it mount the body. to do this I need to make sure I'm happy enough with where its all sitting. body off it is P1050767 by jono_misfit, on Flickr trim, align,clamp, and temporary rivet in front wheel arches P1050768 by jono_misfit, on Flickr P1050769 by jono_misfit, on Flickr P1050770 by jono_misfit, on Flickr then rears P1050771 by jono_misfit, on Flickr P1050772 by jono_misfit, on Flickr P1050773 by jono_misfit, on Flickr body back on P1050774 by jono_misfit, on Flickr then a few strategic rivets in place to hold the body down. P1050775 by jono_misfit, on Flickr I c*cked this up and managed to drill it not in the centre of the arch. Which is annoying. I drilled from the inside and thought I had the CROWN, but evidently not. I'll need to weld up and re-drill another time.

A bit more panelling needed before I move onto buttoning it all up. A load area for carrying parcells / dollies / engine blocks etc. the normal stuff a 5 year old girl will likely want to move. goes in here P1050777 by jono_misfit, on Flickr a handy note taking location was found P1050778 by jono_misfit, on Flickr I converted it to a piece of aluminium P1050779 by jono_misfit, on Flickr and coloured it in P1050780 by jono_misfit, on Flickr then realised there was a negative probabillity of it fitting in one piece. Cut it in half, then recessed the battery access panel to it'll be flush when I make the lift out panel P1050781 by jono_misfit, on Flickr some drilling cutting and folding P1050782 by jono_misfit, on Flickr a lot of sweary words, shouting, stops, cutting and reforming to get the panels made and in P1050783 by jono_misfit, on Flickr a bit more fettling P1050784 by jono_misfit, on Flickr P1050785 by jono_misfit, on Flickr There is still more fettling needed, and then stiffeners and supports to make.

It is. Its not a bad tool. Better than my old one.
I entered a competition to win some kielder tools where you submitted a pic of your project car. I didn't win but they messaged saying they liked the morris and here's 20% off. It could just do with a touch more torque when I'm trying to drill oversized holes.

After weeks of DIY, family illness etc. I finally got a chance in the garage. Continuing with the rear load space on the postman pat van. A support bracket to fix the bed to P1050791 by jono_misfit, on Flickr trimming out the last bit of this side of the bed P1050792 by jono_misfit, on Flickr P1050793 by jono_misfit, on Flickr bracket for the other side P1050794 by jono_misfit, on Flickr bed in for a test fit P1050795 by jono_misfit, on Flickr some more relieving required P1050797 by jono_misfit, on Flickr all trimmed and showing the access hole for the batteries and elctronics P1050798 by jono_misfit, on Flickr I bought some of these brackets so started bending up P1050799 by jono_misfit, on Flickr tacked a few in P1050800 by jono_misfit, on Flickr P1050801 by jono_misfit, on Flickr used as additional mounts for fixing the body down onto strat rivetting the body onto the chassis P1050802 by jono_misfit, on Flickr P1050803 by jono_misfit, on Flickr then the bed needed some additional supports Cut some ali P1050804 by jono_misfit, on Flickr fold up, ah swagey holes I've missed you, and temp riveted in P1050805 by jono_misfit, on Flickr made another for the other side, then an additional brace for the front edge P1050806 by jono_misfit, on Flickr just need to fix in still, but its a bit tight to drill. Will need the 90deg angle head on next time P1050807 by jono_misfit, on Flickr Will see when I get on it again next time.

I've had a fairly pants couple of week laid up with what turned out to be COVID. I was feeling a bit better today, so went out and did some totrod work today. I rivetted in the read bed supports P1050808 by jono_misfit, on Flickr then needed a stiffening strip to support one lip P1050809 by jono_misfit, on Flickr I folded up along the green lines and rivetted in P1050810 by jono_misfit, on Flickr then need a closer plate Cut some Ali and shape it P1050811 by jono_misfit, on Flickr put in some stiffening beads P1050812 by jono_misfit, on Flickr then very carefully drilled and rivnutted the base P1050813 by jono_misfit, on Flickr P1050814 by jono_misfit, on Flickr Its impressive how much it stiffens up the bed a few more rivets in to get it all set P1050815 by jono_misfit, on Flickr then made some little upstands on the wheel arches to finish off and support the front corners further. P1050816 by jono_misfit, on Flickr P1050817 by jono_misfit, on Flickr When I have the whel arches out next i'll weld the tabs on so I don't have rivets sticking through the arches.
