  1. HALF a HORSE.

    Two little bits this time. The carburetor attachment tube was cut down to about 1/2 length. Left long, the throttle cable was rubbing on the outside of the hood and didn't look good anyway. Cut down, the cable and it's outer spring fitted neatly inside the hood. I expected difficulty cutting the tube down due to the limited room for the hacksaw, but it was a quick and easy job. The tube was softer than thought and a junior hacksaw soon went through it taking care not to mark the paint on the surrounding body panels. The cable is just tucked in out of the way at this stage. The brake pedal, non working, was made up from alloy, steel washers and plastic. The lettering is 1 mm approx round plastic rod with the curves of the B and R from solder wire. The solder wire was super glued in place with the remainder of the lettering and other parts fused together with liquid plastic cement. The washers, either side of the pivot point, were drilled and tapped then held together with 8BA c/sunk bolts passing through the assembly. The center of the washers, and the plastic/alloy in between, were tapped 5/16 UNF for a mounting bolt which was fixed in place with lock tight. This item was just eyeballed up from various photo's so just a near enough copy. The last photo shows it loosely fixed in place and still waiting final filling and painting.

    Nothing special about my machining Jim. Just picked it up by trial and error. More error than trial. Mainly small model making stuff plus did odd heavier bits while working on hydraulics. Not an expert by any stretch of the imagination.

    Hi Jim. Last three jobs before retirement were building Fire Engines ( Fire Trucks at your side of the pond ) followed by Hydraulic pumps, motors, control valves repair, testing and building from new components, and finished up assembling Pinzgauer Trucks. Now chief dish washer, gofer and wife annoy-er.

    Thanks Richard. Getting there. Cold in my garage too but pressing on. Have a small heater I can use but it uses electricity. And no, I'm not from Yorkshire. Like your suggestion Manu-matic, I was working on something to add to the standard decals so will use that.
  5. HALF a HORSE.

    Thanks Mark. Would probably be a D-80. Half a D-160, which was mainly used for reference, courtesy of Iain ( slf-uk ) although some details were from D-200's. Would also need instrument panel decals made up. Gauges, wording etc. Just a good close enough copy from photo's as the full size uses moulded plastic panels instead of decals. Still working out what I will need.
  6. HALF a HORSE.

    Thanks Jim. Not quite finished yet. Still some little bits to make or redo plus the decals to sort. Also the trailer to make so I can sit and control in comfort. Think I started about two years ago although a lot of the time was spent looking and thinking. Got a lot of the trailer sketched out on the inside of my eyelids ( wife thinks I have gone to sleep ) and an assortment of parts ready.

    While still at the rear of the tractor, another item which had me head scratching for a long time, was how to provide a support for the steering shaft. As this emerged through the rear panel at an angle due to the differential being in the way, a block of something with an angled hole was required to give more bearing surface than the thin panel. Could I drill an angled hole in an alloy block without a lot of measuring and setting up. ? NO. I had already looked at various plumb blocks and rose joints on eBay, all being unsuitable for various reasons. Then I remembered some small rose bearings I had found in a box of goodie's while clearing at friend John's. Problem nearly solved. The first few photo's show an alloy block being bored and the edges milled to tidy it up. The lower inside face was also milled to clear the tow bar. As is often the case, a change of plan meant that I needn't have removed so much metal. Also seen being turned is a reducing bush for the inside of the rose bearing. The steering shaft is a length of 7mm steel rod. Why 7mm ? Because I had a long length which was originally the drive shaft from an old strimmer / bush wacker ? I was given years ago. There was already a short 7mm thread on one end, made slightly longer, and a new thread cut on the other end. The bearing block assembly is shown next with the unfinished overlong thread. Overlong to start with as I just eyeballed the squareness of the die to the shaft. If it was out of true after an inch or so, I could cut off and have another go. After a little tweaking of the first few threads and checking at intervals all appeared OK. After threading 3 to 4 inches there was no obvious run out. I can do small threads using die holders in my Unimat 3 lathe but it would have been a struggle with this especially as the die was not of the split type. A few nuts were drilled and tapped 7mm. A 3/8 impact wobble drive socket was obtained to connect the drive shaft to the trailer steering ( when finished ). There appears to be no slop in an impact drive compared to a standard universal joint, but not sure at this stage if there is enough wobble. Time will well. The square plug, drilled and tapped 7mm, was part of the previously scrapped 2 speed drill. Just needed filing down slightly to be a good tight press fit. The front axle end of the shaft uses a 3/8 to 1/4 adaptor with a standard U/J to allow for clearance at the differential. These last photo's show how little clearance there is between the shaft, axle and gearbox. Approx 3/16th above and below the shaft. Still need to paint the wheels and hubs too.
  8. Brilliant. Emory sure looks happy with his new toy.
  9. Need to start planning Emory's 2018 Christmas Surprise NOW. Then the last minute panic might be avoided. Or not.

    How to alter the gear lever / shifter so that it pointed rearwards instead of to the right as it was when originally fitted to the ride on Bolens mower. The lever was fitted to the top of the box and operated horizontally back and forward but to get the arrangement I needed, ( I had turned the box 90 degrees to line up the input shaft with the engine ) resulting in the selector shaft pointing to the rear. No problem except that the right hand rear wheel and chassis frame would have restricted the lever movement plus access for my hand. The solution was to cut the lever from it's mounting plate, turn 90 degrees and refix. The idea was to drill and tap the plate, thread the shaft and weld up. Turned out that the plate was extra hard. The center punch lost the fight and I expect the drills would have too. A nut was fitted to the lever to help keep it at right angles to the plate then all welded up. Thanks again Mr Showman. The first photo shows the original position ( taken after I had cut off and threaded ) followed by the end result. The long straight of the lever was lined up with the mounting hole in the plate so that when fitted it would be in line with the gearbox shaft. A bit of tweaking was needed later to cancel out slight eccentricity. Hope that sounds right. A photo of the lever fitted in place. A support bearing was needed in the rear cover plate through which the lever / shifter would pass. A long dig for something suitable unearthed the component shown below. Two were found, one with a 3/8 needle bearing although a plain bush would have done. No idea what they were originally for, but after trimming and drilling one it slid nicely over the not quite round and slightly dinged lever. The end of the lever was dimpled so that the bolt had something to bite into after being threaded through the bush which also has two grub screws for added security. The bolt still needs cutting down for appearance, or something better made, but works well as it is. In reverse gear as shown. Push down for neutral then the other gears. When the tractor and trailer is finished, a suitable gear will be found and probably left with speed being controlled with the throttle and centrifugal clutch.

    . The tractor Emory is restoring for you looks brilliant. Can't wait to see your face at Christmas.

    The original muffler which.was used for the test runs was unsuitable for scale appearance and was also in the wrong position. A 180 degree bend to fit within the side panels was needed. I tried a length of flexi pipe I had but this wouldn't bend into a tight enough radius. A piece of 15mm copper pipe was bent up using an ancient and crude pipe bender ( found at friend John's place ) where else, which gave the required result. The exhaust stub on the engine is approx 22mm outside diameter although the bore is a lot smaller. An adapter was turned up to suit. During the clear out at John's various stainless steel mufflers were found which John had made at work. This one was removed from a mower and cleaned up. This was connected to the copper pipe via an old 90 degree plumbing elbow after cleaning off all the muck. After finding a length of chrome plated water plumbing pipe a posher version was bent up. No prizes for guessing where these two items came from. Not sure how this pipe and the plating will stand up to the exhaust heat, but not the end of the world if it doesn't. An extension was made for the muffler again from copper pipe, as I didn't have anything else of a suitable diameter. This was drilled and the lower end plugged as per the full size. An adapter ring was turned up, drilled and tapped to hold everything together. This ring also located the assembly into the grill surround. The completed parts and after fitting. Still need to make some adjustments.
