As the title suggests, has anyone tried Inconel for cylinder liners? I can get hold of a number of 6 inch long x 35mm Dia pieces all with a 20mm super finished bore, dead parallel and sized to + .005mm/ + .008mm on the nominal 20mm bore. I can get both 625 and 725 grades. Initial research...

First 4 drawings of my Zippo Flame eater in Metric. A very simple engine to build from bar stock.

Hi all! I have recently started a new job as a mechanical design engineer designing and building special purpose machines. This is a short video of the first machine I've been building and thought some of you may appreciate it. The process being done is a Corona treatment which alters the...

Here's a quick vid of my first flame licker, as the title says, made entirely from scrap parts. There's the main bearings and shaft from a VCR head (Damn they're smooth!), several hard drives and a few bearings from an old RC helicopter. All the round Ali is from an old lightning rod, the only...

I spent the morning machining a few large cast iron valve caps for temperature control valves for...

Hi all. I'm just drawing up a small 4 stroke inline 4 on solid works and need a bit of advice on the stroke distance. At present, i have a 15mm (.590") bore and a 10mm (.393") stroke. Can anybody foresee any problems on such a short stroke engine? Cheers for any advice, Wayne

Ok, so as i said in my welcome post, here are a few pics of some amateurish engines i knocked up when i was a CNC turner back in my teens/early 20s. All parts were made ad-hoc on a rather battered boxford lathe and a drill press. No milling, no vertical slide on lathe, just simple lathe with 3 &...

Just dropping a short note to introduce myself. I've been lurking around watching some awesome builds for a while so i thought i'd do the right thing and make my first post here. A little bit about myself - Left school in '86 aged 15 and went straight into a machine shop to be trained in all...
