Anglo Traction

Hope all's well Ewan. Clutch lever done and fitted. Cable was a B+*^h. Very tight job making it up from stainless inner cable and outer sleeve. Nipples made and silver soldered.
Managed to retain lots of adjustment take-up on both tensioners-
 

 
This section is now ready to go on the chassis. Still bugged with decision about fitting tensioner adjustment on the output chain drive?.
Regards.

Outstanding work as ever!

Slow progress, but now have a finished rolling chassis that I can assemble the important bits on. Engine was the first bit to go on-
 

 
Still working on the chain drive and guards on the pump side, with the 'idler'- tensioner set up being the current challenge to design and fit-
 
 
 
Clutch Lever has been a problem, but have now finalised the handle shape and will be cut from 10mm thick block of brass. Will also have a lock lever fitted-
 

 
Lots going on with other things, but will try and improve update regularity.

Making slow progress, hence the belated update. Have been painting, varnishing and making Nuts n Bolts. Sorted the drive chain link problem, so now making up the chain guard wth brackets-
 

 
Ensuring clearances and fixing points were ok. 2 more lower brackets to make and I can move on to the clutch lever and outer cable fitting. Wheels are now shiney black gloss.

Thanks Alan, Been preoccupied with lots of small jobs and pulling together two of the three sections of this project.
The middle section (reduction gear unit) has taken a lot of time and work, as it includes the fuel tanks. They are finished, lacquered, mounted and the fuel gauge nestles between them-
 

 
Still incomplete middle section where I have to make up the cable and lever system for operating the clutch/brake shoes. The last job will be to fill the Reduction gear unit with oil -
 

 
All the brass/bronze work has been polished and lacquered as assembly progressed, with the exception of the engine cowling, as I now have some clear gloss VHT Lacquer for that.
output/fan drive sprocket modified to fit onto a woodruf key and locked in place with a grub screw
 

 
Finalised the location of the modified throttle lever and cable route, which keeps it neat, tidy and handy location. Lever and cable joints are watertight.
Although I will have to change the Carb Air inlet and Choke layout to prevent water ingress-
 

 
Tempted to start the engine for a run soon to check how it sounds with the exhaust. Has a lovely bright blue spark at the plug and the timing is spot on.
Mahogany planks being treated prior to fitting and will be yacht varnished after. Pump drive and location of it is a bit of a headache, but working on it-
 

 
Regards.

Well, later than planned, I've made much progress on the fuel tanks and the mounts. Still more copper tapping to final size, but nearly there with both tanks.
Reserve fuel tap mounting boss finished and light press fit ready for silver soldering shown here-
 

 
Have been making the straps, platforms and retaining rings., the latter from 1/4' x 1/4" x 1/16" brass angle. cut, bent and silver soldered to produce 18 sided rings-
 

 
Eventually the concept in my head and on paper materialised into this -
 

 
Pleased with the strength and rigidity on the base and supports for the tanks (the lines drawn on the copper parts are for more dressing out of irregularities for a better fit.
 

 
A little fettling of the fit around the upper cradles/straps.
 

 
Working on the Fuel Gauge parts at the moment. Will then return to the reduction gear unit and final location of it on the chassis

Slow progress lately. Have been pondering over the tank mounting design, but reckon I've found the answer. 
The cooling fan assembly is now finished and the brass support plates nearly finished-

 
Just finished welding up the Reduction Gear mounting, so can start on prep for painting. Still working on Reserve tank hammering copper before I can finalise the mountings.
Fuel tank support mounts shown in this image-
 

 
Hopefully won't be too long before next update.

Finished making the (12) 6BA Bronze bolts and brass nuts for the Fan Shaft bearing/grease point housings over the last weekend and now trial assembled on the unit. All good-
 

 
 

Many thanks for the comments. Sorry for being quiet for a while. Have been busy when able. Lots of decision making on design and machine time, but seem to produce little visually.
The Tank Cartridges were set up for drilling and tapping. Had to obtain a metre of 10mm studding to make the fixings, as they're quite tall-
 

 
Luckily the igniter percussion inserts drilled out ok, then tapped both bases 1/8"BSP for the fittings.
The fuel taps were done as per previous post, so then just the Air Valve to design and make. Shown in next image on the left-
 

 
The left one shows the top of the reserve tank and the right shows the base of the main tank.
Next job was the fan shaft layout, bearing housings and 'Screw Down Grease Cups'. I had the latter vintage cups, but had to make the housings for them out of cast bronze bar.
Made a lot of work for myself milling to shape just to form the platforms to screw the cups into-
 
 
 
Finished them on the lathe so that I could fit a short piece of brass tube between them as a seal against water ingress-
 

 
Cheated a bit with these, as I'm hard soldering them to large flat brass washers to make the flange for bolting through and will match (in size, not colour) the ball bearing housings also machined from solid-
 
 
 
So here is the basic assembly/layout of the fan shaft and now about to start on the sprocket mount and fan/blades-
 

 
Regards
 

Finished the Fuel Taps. Lots of different set-ups and operations required. Did much of the work while still part of the parent brass rod. Cross drilling 3/8"(9.55mm)-
 
 
 
 
I wanted the tap levers opposed to eachother for access (in the off position), so had to be careful when it came to drilling through with the tapered plugs fitted-
 
.
 
The Tap's cam limit plates had to be soldered together, then to a stub of brass for machining to shape using a rotary table-
 

 
When as much work as possible was done, I cut them away from the parent bar and 'Silver Soldered' the pipe connection rods to the Tap bodies.
All the fiitings are for 3/16" (4.75mm) copper pipe. The tap tapers are 'pulled in' using the correct 'Thackery' coil spring washers and provides just the right amount of resistance-
 

 
A light polish and just need proper 1/16" Split (cotter) Pins to finish off. Maybe blend the joints. Happy with this first time job for me.

Just for everyone's information. I have uploaded the available manual in PDF form for the Hayter Osprey and 21 machines. It's in the orange header line marked DOWNLOADS. Engine data will need to be obtained from the B&S website.

Making slow progress, hence the belated update. Have been painting, varnishing and making Nuts n Bolts. Sorted the drive chain link problem, so now making up the chain guard wth brackets-
 

 
Ensuring clearances and fixing points were ok. 2 more lower brackets to make and I can move on to the clutch lever and outer cable fitting. Wheels are now shiney black gloss.

Bootifull Richard, just Bootifull. 

Unusual design!. it's based on the Archemedian principle. A bit of searchng Hose manufacturers may well produce what you need.
One point about these is that with rubber involved, there needs to be a method of priming with water etc prior to starting up from a dry condition.
 
As for makers info, It may be worth enquiring with the company. Yes, it look's like they are still in business. Here's a link to their 'Timeline' on their website-    MONO PUMPS Ltd 
Good luck.
