Hi All,

It's been a while since my last post. Here are some pictures of the distributor. I finished it (apart from cutting the gear) the other day and to my amazement it actually works!

Regards,
Rob

Great job!

It's taken a while but here's the camshaft. It's made in bits as the two I made as solids either bent when heat treated or broke when I tried to straighten it after it bent during heat treatment.

Fantastic work on your engine! The detail is incredible. I would like to know how you cut your helical gears.

Hi Rob
Regarding the front camshaft bearing ,It has a vertical hole drilled right through the bearing the lower hole is fed from the oil pump and the top hole takes the locating screw for the bearing. this causes a oil leak that is often blamed on the cylinder joint because the oil runs around the edge of the joint an runs down the rear of the engine .
if you drill the holes separately. and don't drill the top one all the way through so the square headed screw that locates it has not oil pressure under it you will have a good chance of getting an oil tight engine. also take care with the fit of the bearing in the case as oil travels' around the outside of bearing to leak out of the locating screw.

Brian.

Your work is an inspiration mate. Beautiful.

Hi gbritnell. I cheated on the gear and bought a gear blank from HPC Gears here in the UK and then machined the center to look like it does.

Thanks for the advice Brian, great idea, I'll do just that when I drill / mill the location hole.

Here are some pictures of the flywheel and clutch and the crankcase.

Stunning gold medal work. Can't wait to see more of it - but don't rush it

Been too busy to post anything recently. I've been putting off doing the crankshaft by doing other bits. Here are some pictures.

This whole project is absolutely beautiful. IE: Saw the distributor, noticed the LUCAS nameplate, saw it was engraved or stamped like an original. The level of detail on the whole build is incredible.

Rob.Barrett, you must have a superhuman (or supernatural?) level of patience and an attention span that is off the scale.

Thank You for sharing this project with us.

Wow!! absolutely incredible! Will be following along, 'twill befascinating to see how you achieve electronics and carburation. Are you using CNC?

Hi All,
Great work keep it up.



Progress so far on the cylinder head. It's made from two bits (to give a water jacket) which are dowelled together with 18 dowels.
