Thanks kquiggle - will have a look at your prints too - appreciate you sharing.

Thanks Andy, really appreciate you sharing - will print some for the three sets of gear cutters I have in tatty cardboard boxes.

Thanks George - really clear even for a beginner like me. Thanks for taking the time to share. Nick

Thanks L98fiero - been trying to track down this info for a while so I can try to build a receiver for my mill and rotary table to accept items still in the lathe chuck. Now I just need to try and make it! 👍

Thanks for the explanation on the motor internals Deerferdog, I look forward to your next instalment - two things sprung to mind - 1) appreciate the warning about (yet) another way to cause friction and grief with SHMBO / your significant other! There are sooo many ways 😂. 2) enjoy your week at...

Whilst you can get some dro read outs with four axis input (and this is arguably the best way to do this), you can also get a ‘summing’ device to combine the quill axis and knee/head axis so that your ‘third’ axis on the display shows the distance from tool tip to part irrespective of whether...

Please keep the photos and commentary coming - it’s really helpful especially for newbie engine builders like me who would like to have a go but don’t really know where to start or who don’t have the knowledge needed to get it right!

Hi Rodrigo - nice start - I’m following as a fellow beginner 😉

Look forward to following along Nigel. HGood work 👍

I’d like to see what’s available and your asking price please.

We have friends in the States (we live in England). Went to send our friend her birthday present and they post office wanted to charge over £50 🤬 because the package was over 2kg (2.2ib). Needless to say the parcel was repacked and some candy removed to get it under 2kg which brought the cost...

I’d go for smooth too - just think it looks a little more ‘finished’ - I like rough castings for steam engines though;)

Thank you Brian. A really helpful and clear answer - I really appreciate it and the tool looks great. Like a41capt (John W) said - ‘and now I have one more piece of tooling to make’ 😉 Great thread by the way - I’m really enjoying catching up on the engine build. Such a great resource thanks to...

Hi Brian, newbie here. Please can you share how you knurled the bottom of the pulley you machined in post 244. It’s quite a narrow groove and the only types of knurling wheels I’ve seen are much wider. My knurling tool is the clamp or scissor type but I guess you could push a ‘bump’ knurler into...

Outstanding. Looks fantastic LeZap. Perhaps a video now you’ve whetted our appetite? Nick

Hi Werowance, I use a spring loaded diamond drag tool. It produces lovely crisp lines and is ideal where the surface is less than perfectly flat and you want to make crisp shallow marks. You use these with the spindle off. For deeper engraving you’ll need to make several passes or use a pointed...

Thanks for sharing the pics and videos - really helpful to see how you’ve done things.

Love the sound of your engine Cooksservices - your workmanship looks great. I can already imagine it in a scale Lysander doing low my slow passes down the runway! Like others have said; I’d love a copy of the drawings, but I believe you said you didn’t make any and built it using the stock you...

Hi John, As has been intimated by others, in my experience silicone doesn’t hold up well to gasoline/petrol - certainly the silicone tubing used for glow engines becomes very brittle when in contact with gasoline and fails quickly and the same appears to be true for silicone sealants (and your...

I’m at the same point. Thrilled to have the stepper behaving as expected thanks to the hard work and knowledge of others (I’m totally new to Arduino), I haven’t yet enclosed the tech bit or mounted mine to the dividing head or rotary table. Hopefully will get some good ideas if other users...
