RE: 5 Cylinder Radial - Brian - 01-12-2020
I have had a few queries regarding the corrected link pin positions on the master rod, so I made 2 dummy pistons, one for the master rod and another for the cylinder under test,
A protractor was stuck with double sided tape to the back of the casing and a pointer attached to the crank shaft and zeroed at No1TDC
the other cylinders where then tested and came up to TDC at the correct intervals, so I am content .

At last the oil pump is beginning to take shape.
Being restricted to house, only going out when absolutely necessary has it's advantages.

Hi Mike
It's a 24x10 Just to get it running!! I had to get a prop now so I can make the flange, all the adverts don't give hub diameter or depth
just bore size.

Mounting the propeller gave me more problems, one being how to make a nice contour on the spinner. so I decided to make a attachment for the lathe, I have studs in the chip tray to mount my taper turning attachment , so I attached a piece of angle in line with the bed and turned a master disk the same radius as the profile of the spinner.
The feed screw was removed from the cross slide and a stylus fitted to it's rear end.
The compound slide was turned to provide the feed.

The cut was taken outwards from the chuck using the powered lead screw, and hand pressure was used to keep the stylus in contact with the master.

I am very pleased with the result and I have a new piece of kit as a bonus.

Nice job Brian.
Tru-Trace made a 3D hydraulic version for Bridgeports, but I've never seen one on a lathe.

Job done? As in the engine is completed? Fantastic Brian, it has been an inspiration to watch this take shape. 5 years since the first post in this thread.
PLEASE post a video of it running.
