Welcome als54, good to see another Aussie in the Membership.
This Forum is the the font of knowledge provided by a lot of smart people.
Looking forward to your project progress.
Cheers from Adelaide.
Early this year I decided to commence the build of a Wallaby [E.T. Westbury] based on the details promoted by Forum Member ECCENTRIC. The build was prompted by the need for a workshop project to keep the grey matter active but not at the level required to complete my Howell V 4. I have...
Sorry for incorrect response. Must have cheated for the very same problem you have picked up. This condition has been queried before on the forum? Been some years since building the Howell.
All the best in your project. best
Just eyeballed the s/plug recess to valve cage clearance on my Howell and would have about 1.5mm clear at the nearest point.
Can`t remember having to cheat in this area to clear a problem.
Cheers.
I came up with the same concern when I built my Howell. Moved on and machined it from a piece of bronze per the drawing details. Have not experienced any problems as the oiling system seems to take of every thing. Hope this belays your concern.
The "Westbury" cylinder block has been machined. A great deal of material had to be removed and one had to take care not to push the 1/4" end mill too hard when working at full depth. Climb milling was adopted which also gives a smooth into corner blending. Crank case and sump material has...
Eccentric`s approach to Westbury`s Wallaby is a fresh approach to a well established model.
Have decided to follow the project and have just completed the engine stand with some minor modifications regarding shape and profile and fastener concept. This departure was prompted by personnel...
I buy all my cutters from Tracy Tools in the Uk. Mostly Goliath brands. Shipping to Australia is reasonable and prompt.

It is paramount that the Master rod, number # 1 cylinder does not come loose. In my case, using Blackmore`s book I thought I would be smart and did not follow the instructions fully and after a number of runs it came loose.
I stripped it down and my notes indicate I silversoldered it to...
Having secured the rivet by swaging you may/will find the resultant opening is quite small and the fitting you suggest would be a fairly difficult operation. In my case I made some brass plugs which were a neat fit [finger pressure fit] into the cap pedestals. To these plugs i had previously...
I purchased my dist. cap from Jerry Howell. Found that with the rivets in place the contact arm was bent up very slightly to make contact with the high tension rivet. The small amount the arm was bent should give you clearance over the s/plug lead rivets. The machining of the distributor...
When I made my Howell V4 [ some time ago] I pushed the rivets into the cap then inserted a rod with about a 60 degree point on it and supporting the rivet heat inside the cap I tapped the rivet stem which splayed it out and locked the rivet in place. I bent the contact arm up to make contact...
Happy New Year to All! [2022 just has to be better than 2021?]
Recently completed a Naylon Viper to the "Motor Boys" plans as a Covid project.
Its a good looking engine and the write up it received back in the 1958 period praised its performance.
This is my first single and required some...
