What do you mean by a kill switch. An isolator or an emergency stop type arrangement.?

Clever chap was that Charlie boy with his theory of 'Natural selection' as demonstrated with this video.

I cannot assist you in it's purpose.

But I can say that some of the brethren here will be mortified to the degree of having to go to see their doctor tomorrow due to seeing a Myford so oily and dirty. --

Thanks for the nice remark Martin. Much external advice though. - It's a 7" dia flywheel.

Here is the spec on the Stuart site. :- **LINK**

I am now 4 weeks into this my first build. - But sorry Jason still no PCD holes yet.!

Carved out the holes in the plates. Diverted from the drawing slightly as I want to give the engine a 'personal touch' with more rounded corners. (I will use that excuse later when I make a cock-up )

The hole is larger on the bottom plate than the drawing says due to me having an a-la Baldrick " cunning plan"

The bearings are drilled, tapped and fitted. Although they do need dressing. Nice snug fit but rotate nice and free with a dab of lubrication on the crankshaft.

While on that subject what is a good oil for running in.? (when the time comes)

.

I wonder the stage I will be at in another 4 weeks.? - Maybe even some PCD holes eh Jason.!

A picture of the item and it's location would assist greatly I would imagine.

I plumbed in a radiator into mine. But it joins the house so was quite a simple job to put one 'back to back' with one inside the house.

What I wish for though is a wood burning stove in mine. Just not got the space though. - It is however probably best as if I had one I would just sit in front of it watching the flickering flames, drinking tea and contemplating the world with a contented smile. .......................... i.e. little work would ever be done.!

What about an old power supply for a CB radio or similar. - Try ebay.!

There is a pot inside them for altering the output voltage. (usually set to 13.8v)

I have a Int 30 fitting on my Boxford mill. It's a standard M12 course.

Edit :- What mill have you got Jack

So would a new single phase pump compared to an separate inverter.!

Here is one :- http://www.ebay.co.uk/itm/Vertex-Coolant-Pump-240-volt-1-8hp-100mm-Stem-/291298603436?pt=UK_BOI_Metalworking_Milling_Welding_Metalworking_Supplies_ET&hash=item43d2bff1ac

Thanks for that.

I did consider this option. But a 1/2 decent one would cost as much as a DRO setup. And a 'decent' one many times more.!

Cheers, Nick

I have a 3 phase coolant pump motor running on my Boxford. It runs hot, very, very hot.! It's only a matter of time before it throws the towel in. Due to it's running temp I seldom use it.

Once it goes fubar I will get a 240v one.

Don't make the sawdust in my bonce hurt any more than it does already guy's. - At this rate I will be fixing the cylinder ends together with wallpaper paste.

This evening I decided to machine the pedistal that supports the outer bearing.

Not the strongest of set ups so I took slow and light cuts.

It seemed to work out OK (except for the auto focus from the iphone )

Over to the mill to do the base side. Again not a major sturdy set up so I again went slow and light.

I gave quite a but of consideration to the mounting as I did not want to introduce even a small twist in the casting that would spring back once I took it out of the vice and leave me saying very rude words.!

It went thankfully OK - I deviated from the plan slightly by putting a recess into the center section of the casting.

Nick

I have been thinking about the backlash and the fact that my machines are graduated in metric. To someone of my limited experience it's a recipe for disaster.!

The options I have are thus. (without taking the parts to my pro engineer friends workshop and using his DRO machines.)

1) Buy a DRO setup myself. - Nice, but I really have other calls on my money ATM so that is probably for the future.

2) I have a 2" travel dial guage. - Buy a second one (20 odd quidish) and configure them to record the X & Y thus eliminating any backlash and my feeble brain issues.

Thanks once again Jason.

Today I made the crankshaft and it's associated casting. Fixing them together with locktight and a 3/32 silver steel pin pressed in through the side.

Then it seemed a good time to machine the bearings.

Have a good weekend everyone, Nick

.

Are there any 'tricks', tips and general advice for drilling the PCD of holes.?

I know it's simple with a DRO fitted. But I have not.!

Cheers, Nick

.

Some more progress made today. Although I did forget to photograph the cylinder end machining as described by Jason.

The piston was made.

And I could not resist stacking bits together to see how she was starting to look. (think I may need to 'fettle' the ports on the cylinder)

Yup. That's what they are.

Cheers guy's

I shall attack this section at some point over the course of the weekend.

I may even use my newly delivered tools from Eccentric engineering.
