Hello All, I'm having trouble sourcing quality 5/8 diameter x 5/16 wide knurls in Australia. I'm hoping to avoid poor quality Chinese knurls from eBay. I can get them from Accu-Trak in the US, but they have a minimum order of USD100 plus about $20 postage. In the UK, Axminster don't seem to...

Hi All, I have a Hercus lathe with a slotted cross-slide. I have the Hercus milling attachment for the lathe, which is my only milling capability. Some time ago I acquired a Myford milling attachment and a Myford vice. Although the Myford milling attachment is less capable than the Hercus...

A friend has stripped the glow plug thread in his RC car's engine. The "head", if I can call it that, is an aluminium disc that is sandwiched between the cylinder liner and the large cooling fins that sit on top of the engine. I could make a completely new part, but I fear it will only strip...

Ladies & Gents, does anyone have any plans for a nice display mount for a small 1cc CI engine? It's an ML Midge (see pic). Chris

My ML Midge plans call for drill rod to be used for the wrist pin. I'm not having any luck sourcing it from my local steel suppliers. Looks like an eBay job. Is this silver steel the same as drill rod...

Ladies and Gents. I thought it would be a good idea to have one thread for my ML Midge build rather than start a new thread for every part. I am building two Midges from a set of metric plans supplied by Ron Chernich. So far I have completed the outside machining of the crankcases, the heads...

Sorry for all the questions. A lot of this is probably bleeding obvious to most of you guys, but it's a whole new world to me. The conrod for the ML Midge is shown in the extract from the plans below. To make the manufacture of them easier and neater I propose to make them as shown in the...

As soon as my piece of CI arrives in the mail, I want to get started on my pistons. Unless I'm going mad (likely), there is no dimension on the plans for locating the wrist pin hole in the piston (see below). Is there some Golden Rule for locating wrist pins in pistons that I don't know about...

I'm building a pair ML Midges and my plans call for L1418 as the material for the cylinder. A Google search provides nothing on this material. Is this a discontinued grade of steel? Can anyone suggest a suitable alternative to mate with the cast iron piston? Cheers, Chris

Hi All, my first post (other than in the welcome forum). I am building my first model engines- a pair of 0.8cc ML Midge "diesels". Today I started on the cylinder heads (see drawing). I'm using 2011 T6. I ground up a 1.5mm wide HSS fin cutting tool and cut the fins. I also tapped the M4...

Hi, I have been metalworking for about 18 months now. Mostly making tools and accessories to go with my lathe. It's a Hercus 260. It's basically an Aussie made metric version of a South Bend 10. Mine was made in the late 90's. It has a milling attachment which is very similar to the SB model...
