Sometimes you need to let go of some things to clear up room. Not just physical room, but also in your head. If you are anything like me, then sooner or later you will end up with a house full of projects that are finished, sorta work or just never really got finished. And sooner or later this accumulation of ideas and tings will grow to restrictive proportions. Eventually you can spend your day going from one thing to the next, thinking about what you still need to do with it and how to do it. Then all of a sudden you've just spent al whole day. Usually quite enjoyably, but definately not productively.

 

So to combat this I try to get stuff finished or leave it in a state where it is really just a collection of parts for the next project. This way I can treat the "unfinished" projects as just temporary thing, without them cluttering up my life too much.

 

One of the projects that I've had kicking around for a little while are my CNC machines. I've got the mill to a point where the table can be driven, apparently with some accuracy. And the spindle can be made to run. It could make chips now. However I've had not use for these machines. The repeatability of CNC has not been needed for anything I've been doing and a manual machine can handle bigger pieces than these CNC's can. So, with a few bigger projects on the horizon, I've decided to move these machines on. I would certainly like to see them move on to someone who will be able to get something out of them, either by using them or pulling them apart or looking at how they've been set up.

So here is a couple of pictures of the setup as it stands, followed by links to all of the posts I've made in the past about these machines.

This evening I started to remove the master cylinder from the Series Land Rover.

Removal of this was pretty straightforward, just remove these 6 bolts from in the footwell. This is all that holds the pedal box in, then with a little leverage from the pinchbar to break the gasket loose and then it's just spin the assembly around 60 times one way, 46 back the other, then 83 times back again. Then lift it up past the fluid reservoir.

It was night and my hands were covered in brake fluid so I didn't get any photos from the top. But here is the assembly on the workbench.

A bit grubby on the outside. That I can live with. I'll put the pedalbox through the parts washer to make it a bit neater before re-assembly.

There isn't much inside one of these things. I'm quite confident this has been a problem. There is a very definite grittyness and hardness on the rubber(?) seal on the piston. So I think that putting the new MC will improve (hopefully fully fix) the problems I've had with my brakes.

 

In this job there was one tool that I found most important.

I was in Bunnings earlier and almost walked past this. $9 for the holder add a little more for the bulb and all of a sudden it is easy for me to get work done once the sun has gone down. I have put a LED bulb because I won't burn myself on it, I can put a brighter bulb in it and I don't need to worry about breaking a hot filament through rough handling.

 

In the next few days I'll be putting the new one back in so stay tuned for that.

 

Cheers,

Who can recognise this? Any why would I be putting this in my Series Land Rover?

 For those who don't spend their spare time getting to know all of the parts in your engine bay by name; this is the compressor from an automotive air conditioner. Now why would I be wanting to put this in the Land Rover? I mean there's no point trying to cool it down, Series Land Rovers are notorious for having lots of air leaks. This one doesn't even have windows yet for goodness sakes.

This weekend I got some good progress on the Land Rover. One of the things I've worked out that has been hanging over my head is the brakes. I've reassembled the brakes on the front axle enough to test for leaks in the system.

This was my setup. A pressure bleeder with the brake fluid I had left in it, pumped up to 14-15psi as per the owners manual. However the pressure would bleed down slowly. Maybe 1psi every couple of minutes. With no leaks between the pressure vessel and the master cylinder it had to be leaking somewhere else. 

Turns out this is where it was coming out. It seems to be coming down the link for the pedal then dripping from the linkage onto the floorpan. Looks like I'll need a new MC. I'd been hoping that I wouldn't have to replace this as it is very awkward to get to and all of the screws seems to be plain steel and locked in tight by rust. At least I will have some time to read up on how to remove the MC and soak the bolts before the new one arrives.

 

Keep an eye out for another post soon with the other stuff I've been working on over the last weekend soon.

 

Cheers,
