Mastiff 4-stroke petrol engine

[RF78]

Hello,
Has anyone the book from Leon Mason: Building a 4-stroke petrol engine the Mastiff, for sale.
I know i can buy it from Hemmingway,but maybe it,s collecting dust on your bookshelf, i need the plans to complete an engine that is made for 60 %, but the plans didn.t came with it.
Greetings

I got mine off ebay and it is an engine i will start building in the near future , it is not an easy book to find especially here in Australia . You could also take a look at the model engineer back issues as i think len did a write up series on this engine , you would have to purchase a digital subscription to get access to the archives though .

The Mastiff engine is made in inches measure. In fact it's not difficult to use measure tools in inches after you has learned to read inches after 10 minutes.

Thanks for the help, I will give it a try. I will look for a tread converting table as well, because I have lots of metric screws o. Stock.

No problem to use metric screws in the engine build in imperial measure. Take the nearest in measure and replace with metric to example 1/4" bolt with M6 bolt.

Hi Robert,
I wrote up a build of Mastiff on the Model Engine Maker forum:

http://www.modelenginemaker.com/index.php?topic=6419.0

Most of the threads I changed to metric, along with some of the dimensions. I left the main design sizes as they were so numbers like 25.4 mm appeared a lot.

Regards, David

thank you all for the advice. I would build this engine again, with two carburetors , for me but not to offer. Too bad for the lost photos of Deltatango's work. Superb engine. Robert.

Hi David, do you share the metric plans? I just bought the book from Robert. But I read that the drawings in the book are most pencil drawings.

The pictures are there now, I'm not sure why they weren't showing earlier. maybe OneDrive was being awkward.

Hello David!
Are you going to make your revised plans available? I'm the one interested on that.
Tks,

Edi

OK folks, I'll give some thought to getting the drawings fit to share. It won't be this year - I'm now well into holiday mode and at the beach.
