Just wanted to share this with the group. My son and I were sanding the bore s and pistons for the 22RE engine. We got talking and figured there was an easier way so we made these. https://www.thingiverse.com/thing:3167802
ID and OD sanders for the drill to speed it up. they work really good and so I thought I would share.
Hello, as a proud Subaru owner I'm a big fan of the Eric's EJ20 model, but I have a Justy whitch have a EF12 engine (1.2l inline 3 cylinder)...
I have a Fusion360 and I never tryed to design something that complicated... Hope I started the right way - with the block...
I will use the same bearings as in the EJ20, M3 bolts (maybe with brass inserts on some places), maybe thicker magnets, GT2 timing belt, and same electric motor (but I'm not sure where to hide it), also I didn't find very good springs for the valves so I hope someone else got something cheap (from aliexpress would be cool)...
If anyone have any tips I will be very happy, I will also share anything I will find useful for others trying to design their engines :)
I'm hopeful that i'm just missing something silly. I printed all the parts and just assembled the camshaft. I had purchased the official hardware parts kit but I did not have a 175mm threaded rod in the kit. The only threaded rod in the kit appears to be about a 198-200mm.
Regardless, I was able to get all the parts of the camshaft together but where the Camshaft Assembly sheet shows 1.16 I'm measuring 2.7cm... so it appears my measurements are larger than the Assembly Instructions yet the REAL head scratcher is that my camshaft is ~1.3cm shorter than the span of the main bearing.
