  1. HALF a HORSE.

    This photo shows the chassis on 4 wheels, still with the first style front hubs and with new tyres fitted. Tread wrong way around I know, wheels just roughly mounted. The front tyres are 9 x 3.50 x 4 made for mini motor cycles fitted to the Bolens 4" hubs. The 9" tyre was better proportion wise than the 10" previously fitted although I have not been able to find an inner tube with a straight valve. The bent valve finished up hard against the rim when inflated. A little mod later improved things. No photo of this yet. The height difference of 2:3/4" between the engine and gearbox shafts can be seen. Just by chance an old Picador double bearing found at John's had the same C/L's and with a slightly cut down base was a perfect fit. Now what to use to transmit the drive from top to bottom. Sprockets and chain from old mowers were dug out. Most were too large to fit between the frame or were double sprockets. The smaller sections were cut off and after trying various combinations things started to look workable. After trying various chain lengths, too short or too long, a cut down mower tensioner was fitted but didn't look right. Another sprocket was found which fitted between the frames but had the wrong ID. This was bored out and welded to the gearbox sprocket ( thanks Chris ) after mounting the pair on a suitable size bolt. After this, the existing keyway in the small sprocket was used as a guide to file out the larger one. The result was a nice tap fit on the gearbox shaft and key and also after altering the chain did away with the need of the tensioner although this could be refitted later.

    And he has a BIGGER trailer now.

    There will still be things going North. Got a little pile already.

    Still got the front axle from the yellow Bolens Norm. Yours if you want it. Similar to the Westwood.
  5. HALF a HORSE.

    Can't remember exactly when, but part way through the early stages of the build it was thought a good idea to see if the engine would run. It had only been roughly assembled up to now so carb cleaned, new fuel pipe fitted, bolts tightened and so on. The recoil starter was a problem. I had 3 of these, 1 complete and 2 in pieces. The complete unit was fitted but locked up when the cord was pulled. I had this apart 4 times before finding the problem. A missing spacer washer. Wasn't sure if this washer should have been there but it did the trick. One of the other units had one, the other didn't. After the 4th assembly I was getting the hang of fitting the recoil spring. Clamped to the bench, petrol in the tank, starter pulled, and pulled and pulled, nothing. No spark. Cover off, points cleaned, they were furred up, and away it went. There was a knock which appeared to be from crankshaft end float. A PM to Richard ( Anglo Traction ) who suggested that the knock might disappear when the engine was under load. This proved to be the case. Thanks Richard. A few bench test runs followed and the engine appeared good to go.
  6. HALF a HORSE.

    As the front axles were 3/8" and the Bolens wheel bores 3/4", bushes to fit both were required. A hunt through my bits and pieces for something suitable drew a blank and nothing found on the internet. I could probably have made these up on my Unimat lathe but no suitable material to hand at the time. I came up with a different idea using parts lying around. New axles were made using 10mm coach bolts and nuts, stainless tube and 10mm bolts. The tube was threaded10mm internally each end, it was luckily close enough to the correct tapping size. One end was screwed onto the cut down coach bolt after fitting it to the angle iron hub, the wheel retaining bolt fitted in the outer end. Suitable bronze bushes with the correct ID and OD from the spares box finished the job. These look a bit over the top but didn't take long to make. Took longer looking for the bits. The king pin was left at 3/8". Weld between the two inner ends made the unit extra rigid.

    I DO, I DO, and I've already TOLD you. Too much tea today has watered your brain down Chris.
  8. HALF a HORSE.

    The Bolens axle was cut down and drilled. The shorter end didn't need altering. The length was just right and the original wheel retaining bolt hole was also used for the model. The other end was a pain in the ++++ though. Tough to hack saw through, although it could have been worse, but the 5/16" hole was a ( censored word ) to drill. Finally got through with an assortment of drill bits, cutting compound and my lashed up drill press using various speeds and lots of naughty words. Luckily I only had to drill this one side. Now, what to use for the front axle bushes. A long time was spent looking through my piles of bits and weighing up all the options. Some bits had the correct OD but too large on the ID and so on. Still wanting to use what I had to hand, a piece of engineering plastic was used. Not sure, but I think this is Delrin or Acetal or similar. A short piece was tapped into copper tube to hold it rigid while drilling in my Unimat lathe. I was surprised to see blue swarf as the material is black. After drilling up to 1/4", the bore was opened up on the drill press. Can't remember the drill size but slightly under the OD of glacier bushes which were tapped in afterwards. These had an ID of 3/8" which was the bolt size I used for the king pins. If these bushes were later found to be unsuitable they could easily be changed. So far, with a few test drives that the Showman and I have had over rough ground, no problems have been found.

    Me too Nigel. I think Chris took those two photo's especially for me.

    I normally look first too Norm. Didn't this time.

    A few photo's of a few welded up bits. The welds on the rear end of the chassis were nice and neat. No photo's of this. The welder decided to be naughty at the front. Wire feed kept jamming until speeded up which resulted in heavy welds. Some ground or filed down and others left as will not be seen. The used Austin 7 king pin used for the axle pivot seen in the third photo. A bit rusty but good enough to use after a clean up. The chassis was cut away to allow for more axle swing. The rear wheel adapter hubs were made up from 2" thick walled tube and round plates into which the tube was welded. The plates already had bores of near enough the correct size. The cut to length tubes, after a lot of head scratching and measuring to make sure the holes would be in the correct place, were drilled 5/16" using a standard center drill for the first hole. I was going to use this as a guide for a 5/16" drill to spot the lower hole, followed by gradually opening up with other drills, but found a long series 5/16" center drill which did the job in one go. This also did away with numerous height adjustments on my not very accurate drill press conversion. The plates were drilled after marking out using a card template which was cut to just fit into the wheel dish and over it's hub. 4 holes were also drilled through the wheels using the same template. This ensured that all holes lined up. Even though my drill conversion was a bit of a blacksmith job, after drilling the axle shaft I found that it and the hubs lined up almost perfectly. Before converting this drill press I had ordered a bench drill from Germany. Good reviews etc. It arrived 6 days later. All excited I opened the box. Hmm ! All very nice but how can I drill holes with a heavy duty garage style BATTERY CHARGER on wheels ? Email to Germany, "Don't know how that happened, send it back carriage paid and we will send correct item" Did that, no correct drill, refund instead. No explanation. Followed this up by more research. Ordered another make bench drill from Screwfix. Delivered from London next day. More excitement. Unpacked, assembled, tried out, dissembled, back in box, taken to Screwfix depot nearby and refunded. There was more side play on the chuck when fully extended as there is on my conversion. Plus, the table was only a pressed metal affair which flexed with hardly any effort. Didn't expect a Rolls Royce job but.!!
  13. Happy birthday Nigel

    Happy Birthday, Birthday Boy.
  14. Looks brilliant Gareth.

    Looks a good show Chris. Like the green model Scammell.
