That was hilarious! I did not expect the Superman tee shirt.

I actually had a physics professor in college who used archery to illustrate ballistics. Yes, we actually got to shoot real arrows in physics class. Not sure how he got away with that one.

Nice one Greg, Thanks.

Todays job was to make a start on the head.
When I bought rhe boat 12 years ago I noticed a few strange washers under No 1 heater plug, but as the starting was good I left well alone, but now semed the time to investigate.

   

   

As suspected a broken heater!!! This left me with the broken part firmly jamed in head. so i made a guide bush for a drill that was a little smaller than the hole. and drilled thro to the correct depth , and the broken part came out with the drill.

   

   

A clean up pass with the correct size drill to clear the carbon and we will be back with 4 new plugs.

Slowly Slowly---Brian.

Brian,

What was the deciding factor that made you decide to tear into the engine? Was it something you've been meaning to do or did something fail?

Brian, did you use a left hand drill to perform that nifty extraction?

Hi tom
The reason for all this work started with the failure of a oil seal in the injection pump, over a period it leaked fuel into the sump thinning the oil.eventually leaking out of the crank oil seals into the bilges. So the pump required repair ---the engine oil seals are suspect---and i had no idea how long the motor had been running on thin oil. so a total inspection was in order--Sometimes I run this motor continually for 3 days, so it must be right. also it gives me the chance to do other work,like the heater plugs, and a rewire of the engine room/hole, etc.


Hi steve
The part that was jammed in the head did not have a thread so a normal drill worked OK.

And Sasquatch. happily plan "A" worked so B&C are not required.


Best regards to all Brian.

Needed a spanner wrench to fit the round nut on my fin cutting fixture.

A friend is having trouble with the Ford Industrial engine in his log skidder. Im giving him a hand to get it patched back together. Among the problems, when we did a pressure test on the cylinders one of the exhaust valves were leaking bad. He pulled the head and removed the offending valve. The valve was good but the seat was burnt in one area. Decided to regrind the seat for him, thought I'd post a couple of photo's, don't think this sort of work is done much anymore.
A bit of background on the tooling.
Tom, a grumpy old bugger (would have fit in great here) had a garage in the village, I'd drop in regularly to harass him. One day out of the blue he says Inglehart, you need that valve grinding equipment thats out in the shed (I'd never seen it). What the heck for I tell him, he chuckles, your the only one around here that might ever figure out how to use it. So home I go with a K Olee valve grinder and Black and Decker seat cutter, complete with all the guides and stones. Its been sitting for a few years here, Tom is long gone unfortunately but his tools live on.

This jig cuts the wheel to the proper angle for the seat in the head.

The wheel threads on to the arbour and a hex drive on the motor turns it. A small diamond does the cutting.

The set comes with a set of mandrels that expand into the valve guide in the head to center the arbour and keep it square. Drop the arbour onto the mandrel and start grinding.
