Its been a while since my last update - got a bit distracted during lockdown with other projects - including the rewiring of a denford CNC micro mill. This weekend I made some more progress on the Mini Caterham project and made the rear wheel hub bearing carriers. The parts were made using the...

Yea if it rotated in the collet the the setup would be ruined. The collet had a good hold and I took very light passes. It wasn't possible for me to put it directly in the 4 jaw Chuck as the small diameter of the shaft combined with the offset ment on of the jaws wanted to pass the centre of...

Back at work yesterday after being ferloughed for 3 months but managed to find the energy to turn the crank from a grade 8.8 bolt as one part as suggested.

Thanks for all you comments, I think I know how to approach it now.

Thanks Jeff, I've sent you a message

Thanks I'll have a look

Yea that's a centrifugal clutch. I plan to make a single speed gearbox initially but in the future I may look to add more speeds.

Great idea, I'll have a look at what sizes are available and if it work with what I have. 👍

Hi all I plan to start making a straight 4 cylinder engine in the near future. My first one. Like lots of you probably do, I spend lots of time thinking about the setup for each part Recently I've been thinking about the setup(s) required for machining the block and how to properly align the...

So over the last couple of weeks I've made the steering rack for my mini caterham project and got it fitted. Good to see some moving parts I've also have a nose cone 3D printing so I can work out what space I have for the radiator which I've bought. (PC radiator) I've also bought a module 1 -...

Some very interesting reading. Thanks for posting. Once I get to the piston and cylinder I will be reading all this carefully. Some more progress made yesterday with the main / crank bearing made

Thanks for the tips. I'll have a look into turning the crank as one part. How do you approach turning a crank? At the moment I think I would do it between two centres

Last week I started on the crank case cap. However after a few minutes of frustration with my lathe I decided to take the cross slide apart and open up the diameter of and replace the gib screws. The hex in the original ones were rounded and which ment I couldn't adjust them anymore. However...

Thanks, yes that's great!

Cool. I don't suppose you would have any contacts that could help me get hold of a cad model on the body work that I could scale to my chassis would you? I'm planning on 3d printing molds and making carbon fiber panels

Very nice! What's the ground clearance to the under side of the chassis on a full size one?

Very interesting! Do you work for caterham?

Thanks George good idea. I did have a question regarding the flywheel. Is there anything critical to the details of the flywheel? I.e. mass? Or can I make any flywheel of my design to working with the crankshaft?

Great, I wish I still had space for a full size car project. My last car project was the rebuild of a Mazda RX8 Wankel engine.

So last year I bought drawings from @gbritnell for his straight 4 cylinder engine. I intend to build the engine in the future but have decided that I'd like to have it drive a car. In the past I have considered building a caterham / lotus 7 replica but never got round to doing due to fund or...
