    Thanks Ed. To be honest, it's more off cuts / left overs more than shelf items. If i use off cuts i get the material that much cheaper. Makes sense to me and if i wanted to be 100% accurate i would have to have alot of these components cast and thats a no go for me. Jon

    I have been busy making the track return roller hubs. As usual, I have been using materials that are locally available, rather than ordering specific sized materials, so a little bit of adaption is required. The main hub starts as a piece of tube cut and machined to length, then a flange is welded in each end of the tube and then set on the lathe so that the rings can be bored out to suit the centre bearing housing. This bearing housing is then welded in place. A ring is then welded on to the outside of one end of the tube for two reasons. Firstly to give the impression that the material is thicker and closer to the originals dimensions and secondly to give the polyurethane tyres something to bond to when I cast them in place. This assembly is the reset on the lathe and bored out to the bearing diameter size and correct internal lengths. A separate ring is then welded on to the opposite end of the hub, for the same reasons as the first. Reset on the lathe and then again faced to the correct lengths. Each time the hub is reset in the lathe, for each operation, it has to be adjusted so that the assembly rotates true to within 0.02mm, so you can see its a time consuming process. Once the main hub housing is complete, the next items that need machining are the two retaining flanges. The rear flange houses an oil seal and the front flange locks everything in place, As with the main housing its not a quick or simple process, hopefully the pictures are self explanatory. Finally, the finished assembly and a picture of an original return roller on the PZ2 at the Bovington Tank museum. I hope that makes sense. Jon

    Well Brdm, you are not the first to mention youtube but i have to admit, that apart from 3 forums, where i post updates on projects, emails and purchasing bits, the internet is not really my cup of tea. Saying that since your suggestion, i am now investigating putting it on youtube, that is, when i work out how to do the videos and everything else. I would consider my workshop as basic but thats compared to others that i used to work in. I have a lathe, a bridge port milling machine, another milling machine, 2 pillar drills, a basic bender and a compressor.plus of course a welder. No cnc's, although i would love a cnc milling machine and lathe as they make life so simple and quick. Maybe one day i will make some money out of this and treat myself, who knows. The beginings of the track return rollers Jon

    Track return rollers shafts manufactured and bolted in place. Jon

    I have at last, managed to fabricate the suspension arm travel stops / bump stops and attached them to the chassis. It seemed to take ages to complete these items but we have been in a perma frost for a week, that seemed like a month, snowed in and the workshop was frozen up, thats my excuse anyway. They are not perfect but as near as I could get them, the grey one is from the Bovington tank museums PZ2. For my next trick I am going to make the track return rollers, now that will be fun. Jon

    Evening all, I have managed to finish the 9 remaining suspension arm shafts and associated components and the spring retention rollers, well that's what I am calling them. As I don't have any technical construction details of these, this is my version. The spring retainer rotates as the spring is flexed by the suspension arm, the unit consists of a shaft on a back plate and a housing. The housing contains an oil seal at the inner end, followed by a bearing, then a spacer followed by a second bearing. This is the pressed onto the shaft and held in place with a washer and a bolt. Another spacer is followed by a 3mm section o ring and an end cap, all held in place by a circlip. The last picture is an original unit. The original has an oil / grease point in the centre of the end cap, on my version this is just a dummy that can be unscrewed and replaced with a grease nipple so that the unit can be filled with grease on final assembly.

    Making money doing this sort of work would be very nice, all I need are some customers. From my experience most of the locals here in midwales are more interested in tractors and sheep. It seems that mid wales is too far from civilisation for most to venture. The hull, turret, upper hull are all 6mm to keep the weight down but packed out where necessary to give the impression of being thicker. The curved mantlet is actually a 12mm x 6mm frame skinned in 1mm. The suspension components are made of various sized material. Jon

    Thanks but its nothing, just flour, sugar, butter, eggs and lots of cream, jam and chocolate. Jon

    Although I had drawn the suspension arm location shafts on CAD, I decided that I would make a set just to make sure that some plonker, thats me, hadn't cocked up. Well it turns out that I hadn't. The outer bearing housing retainer has an oil seal pressed in to stop the ingress of dirt. Then there's the complete set, bearing housing retainer, shaft, bearings, the relevant spacers and finally, the complete set installed in the hull. The hole in the end of the shaft is for a greasing point that I have to make, see below. I am not going to weld the arm to the shaft until I make the wheel axles and I don't think that I will do that until I have made a wheel. Only 9 more sets to make. Jon

    Its going quite well apart from a virus that slowed things down somewhat. As you can see the curve on the front of the hull was a success with lots of leverage and heat, which was very welcome in the snow. All ten suspension arms have been fabricated and my next job is to turn the locating arms that locate the suspension arms into the hull. Oh and I made an Easter chocolate cake, which my wife demanded with menaces. Jon Jon

    I had quite a good day and tomorrow I will hopefully bend the front of the hull. The 4 front bearing houses are tacked in ready to be fully welded when the hull is turned on its side. Jon

    I am not sure eddy, you have certainly got your hands full with the covenanter. Its a challenge that I would love but I would imagine finding the parts is going to take time, a lot of money and more important than all that absolute dedication to the cause. You have my respect for taking it on and I am looking forwards to the updates. Jon

    There doesn't really seem much to show you because I have been fabricating and machining lots of components ready to install into the hull. It all takes loads of time for what seems very little result. Firstly sorry for the quality of the pictures the light wasn't very good tonight. As you can see from the pictures ,the main hull has been welded together and over the next week I will attempt to weld the various components in place. I hope by tomorrow night to have rolled the front of the hull but its a major job with my very limited equipment so it may take more than one attempt but we will see. The 3rd and 4th pictures are the inner and outer bearing houses for retaining the radius arms into the hull side and the plates with the holes in are strengthening ribs. First job tomorrow, before rolling the front, is to get the 4 front housings in place and accurately in line. Not an easy job by hand, these housings would have been machined on a special machine so that everything lined up perfectly but I don't have such a machine so fingers crossed. Jon

    Sounds like a nice project keep us posted and good luck. Jon
