I have posted some stl files in the foundry and casting section

3d printers are great for making patterns but files seem to be hard to find, so I thought that I should share mine. The smaller flywheel is from the 140 mm pattern scaled to 0.65 in the slicer program. The larger one is a 90 mm pattern at full scale, the blue patterns are lumps to provide hot...

I have tried casting with brass? wear plates from a cat grader and seem to be getting a lot of shrinkage. has anyone else had experience with these. picture shows a mini anvil in aluminium and brass, the tapered brass sprue has been cut off, the riser is still there. I don't think that air went...

Nearly finished, crankcase cover is plastic printed

I have made a hopper cooled hit and miss engine from the Depenbuch plans and decided to do an air cooled version, no hit and miss gear at the moment. It has 6 inch flywheels. the main things that I tried with this model are home made cast iron rings (O rings up until now) and I wanted a magneto...

I have been thinking about mounting a hall sensor in a dummy magneto for a while now and finally got around to having a go. I have a 3d printer so thought that i would print something to give me an idea of scale, for my first attempt at 3d cad i was pleased with the result. the template was the...

I have always disliked the handwheels on my mill (HM48) they just don't feel good. so I decided to change them, found some on ebay, https://www.ebay.com.au/itm/188mm-8-3Spoke-Round-Iron-Hand-Wheel-for-Milling-Machine-Lathe-Superb/153750064944?hash=item23cc37cf30:g:ajkAAOSwyWFd6Da0. I am really...

A couple of years ago I built my first IC engine and my son really likes it so I thought that I would make him one for Xmas. There are no plans, I just made it up as I went along. I hope to make a few improvements to fix some of the things that didn't turn out as well as I would like. Some of...

This is a 1/2 scale Buzacott 2HP which is the Australian version of a Fuller and Johnson. it is built from castings, I have had the castings for about 5 years but was too scared of messing them up so I built a few barstock engines first. I have a full size Buzacott engine, an upshur hopper...

I am looking for plans or just line drawings of a very simple early tractor. here is a youtube video of the sort of thing that I am after . it is an open crank single cylinder, basically a traction engine with the steam replaced with an IC engine. I don't need a faithful recreation just...

Finished the transporter and mounted the ignition for my latest engine. Just need to tinker with the hit and miss springs to slow it down, I will run it in a bit more first. Based on these plans...

found this engine on the Banggood site and was wondering if it is a copy of something and if so what? go to 3.30 on the video to see the action

finished 3 Upshur engines. They are a good project for a relatively simple ic engine. The vertical and hopper cooled have hit and miss the air cooled missed out because I used five spoke flywheels that came off a previous project. they run on shellite (coleman fuel) and the ignition is a rcexel...

Add a bicycle speedometer to your finger engine and the grandchildren can have competitions

What a good feeling. I spent 6 months on this and was getting worried towards the end that maybe it wouldn't work.
