The bronze balance weights and custom bolts complete the crankshaft assembly...

Been working on the crankshaft this week, but have now pretty much got there. Just the oil passagway holes to seal. First time making a crankshaft from solid so fairly nerve wracking as more more and more invested hours are at risk of a c*ck up! Pleased with final result which spins nicely in...

Yes, very satisfying. As I mentioned, there was a huge runout error in the baseplate of the chuck I first used, but luckily it resulted in undercutting one side of the cam. So when I swapped to the collet fixture instead I was able to save the part by recutting it and removing the excess...

Spent some challenging hours this week working n my first ever camshaft for the Kiwi. First struggled to get the Camcalc software to work but was ably assisted by other forum members - thanks! And then suffered a serious run out problem which I tracked back (eventually) to the baseplate...

Thanks for your help towards me making my first set of cams for my Kiwi Mk II! Despite a few fairly major run out issues with a cheap rotary table chuck, I was able to save the work and end up with a pretty good result for a first effort. Onwards..

Hi Jason, that is really strange. I downloaded the spreadsheet this morning and it was giving me inconsistent numbers (see attached). But having re-downloaded it, it seems to be working correctly. Very odd!

It does look like there may be a bug in the spreadsheet however. The lift numbers look correct for the 1° increments but if you look at the 2 and 3° increments columns, those numbers do not match their equivalents in the 1° column. I did a quick cross check with the original CamCalc running...

Even better Jason! That has done the trick as I was able to go to your dropbox location and access the spreadsheet. It's an improved version to the one I was looking at with a useful graphical representation of what the cam will look like. Thanks for the pointer! Richard

Bingo!! I have finally managed to get it to run. After much web searching I found that if you load a free Chrome extension called CheerpJ Applet Runner it allows Chrome to run old applications that require a Java extension. Thanks all for your help. Cheers Richard

Thanks Craig, but I don't think this is what I need unfortunately. I'm looking for the CamCalc which generates a table of cutter heights that can be used with a rotary table to profile a cam on a mill. I did download this link but it seems to be something different. Thanks for looking though. R

Thanks Andrew! As requested I've uploaded the photos that show the spring steel clip you made for your Kiwi. Many thanks Richard

Hi there, I am currently building a kiwi Mark II engine and now need to machine the cams - I want to make them harmonic. Unfortunately I am a Mac user and I'm finding it difficult to access the CamCalc application. Has anyone had success using this or another solution on a Mac computer and if...

Here is some more progress on the Kiwi. I've been working on the rockers and other elements of the rocker assembly. Some sanding and polishing still to do, but overall these components have come out ok.

Thanks for that. I have ordered a set of points so will see how big they are vs what you mention. Hopefully they will do.

Thanks Andrew!

Thanks for the comprehensive reply, really helpful! Harmonic cams are clearly the way to go and will use the vertical mill and rotary table option when II get to that stage.

Thanks Vince. Your thread has been extremely helpful!

Thanks for this. This will be my first go at cutting cams and is a bit further down the line. Excuse my lack of knowledge, but what is the difference between cams cut the ETW way vs harmonic in terms of ease of execution and benefits? Thanks

Thanks for that pointer, are you able to share a photo of your perforated cover clip?

And here are the valves, guides, collars and collets. I had a bit of bronze spare so upgraded the collars from MS for a bit of bling. First attempt at machining valves, so pretty happy with how they have come out. And they seem pretty air tight in their seatings even before any grinding, so...
