Water pump impeller machining on the rotary table Water pump parts i've tested the pump, and it does work, but I couldn't call it a very fast flow. It's fine at, say, 2000rpm+ but below that it's a bit of a dribble. Trouble is most of the time it will be below that speed...

Some pics to bring me up to date:- Awkward counterboring op on water outlet... Valve assemblies gapped and ready to fit.... Tool for screwing in valve assemblies... Valves fitted in head.. The valve assemblies are sealed into the head on a ptfe washer. This means...

Well, nothing to report really. I got a bit bored with it after finishing those inlet pipes. they were the hardest things I've ever made, and I'm glad I did them, but everything else seems like a bit of an anti-climax now. Obviously I need to get the engine running at some point but can't be...

I did the ptfe cap thing in my pins. Not fired it up yet but I'm not anticipating any problems.

Busted, I would get a pack of 10 solid carbide circuit board drills and just have a go with them before doing anything exotic. I bought 10 x 0.25mm drills for a fuel injector and these went straight thro silver steel plate to about 2.5m depth, and that was only about 1000 rpm. Deeper than that...

Longrat, I'll be 23 next birthday, and I've had my lathe and miller for nearly a year now! ;D (53 really) KustomKB, I've spent too many years messing around with cars before getting down to some proper machining. My last 2 projects were, a 16" binocular telescope, and a 1/8th scale...

Welcome Chuck, How about trying a binoscope. I don't use mine much since I caught the engine bug!

Some random photos....then I reckon I'm fully up to date. When I was trial fitting the rods recently I got so frustrated messing about with the split bearing shells that I decided to rivet them to the rods and caps. I used some 1/16" copper tube so it's nice and soft if any touches the...

Hi, yes I have a bit of shop experience, but I am 95% self taught. I have been meaning to clarify the title of this thread. It should be called 'first engine project', not 'first project' as in the first time I've ever made anything at all. Cheers.

To go with the inlet pipes I also need a new inlet manifold and plenum chamber. I kicked myself first for all the wasted work on the existing ones, and then got on with it. I try and use the dividing head wherever possible these days. It's ideal for these sort of jobs with odd angles allover...

You're all too kind. Hope these drawings make some sense. I used a ball nosed cutter, and worked out the x,y and z measurements on the cad. The other variable was the dividing head angle. It started off veryslow but I soon got into the swing of it. I reckon30 hours to make one set of pipes...

Finished one side. The other side will have to wait a bit till my blisters heal up!

Blimey, doesn't time fly? Some more pics and an update. I've been finishing the liners and pistons etc. so the internals are just about done. I then decided I had to have some inlet pipes similar to some full sized ones I had on my old Chevy motor. Not really a job for a manual mill, but I...

Sorry, just been on hols for a week. Don, on the large AN fittings the lock nut squashes the liner and outer braid onto a tapered alloy inner, similar to full sized practice. On the small ones, pictured above there wasn't room for this, so I went down the nut and flare route. When the nut has...

This is the drawing of the smaller fitting, which is a 1/4 scale version of a 6AN fitting, the usual size for a full sized fuel line.

Thank you for your continued comments. George, I made the AN fittings. the larger ones for the oil pump are made to seal on the tubing similar to the full sized ones, ie the conical bit on the fitting goes up the plastic bore, and the nut screws on to the outer braid to lock it on. The tubing...

Still can't quite get the idea of multiple carbs out of my head. Made a new plenum last week but still not 100% happy with it. Some random pics:- Injection mould for the plug caps...... small fittings for fuel system.....

Longrat, I wouldn't place too much emphasis on the nitric acid stage. I only did it with the cam covers as there was too much work gone into them to balls it up at the last moment, and as I'd used the steel shot to peen them. We shot peen a lot of titanium at work, and most of these components...

Mackye, the pulleys on the cams have +/-15 degrees adjustment built in. The 4 bolts run in slots on the pulleys. Cheers.

Thanks all. The satin finish on the cam covers was only arrived at after numerous trials with bits of ally in the blast cabinet and the anodizing tub. The final method used on the covers was firstly to blend all the edges in with fine foam backed sanding pads, then polish on the buffing wheel...
