I like the cylinder, did you try screw cutting it first or was the milling the first option?

My experience is pretty basic, however we tried to use them at work in place of hex cap heads, the tools were always snapping off. They all seemed to be too hard or cheap whichever applies to them.

Heat always gets stuck bolts out that have had too much loctite on them. In ten years of trying to get the fitters to put a small amount on, i think its finally sunk in that too much is not good. I live in hope

Brian

Nice one. I did not know until recently that if you rub them together they should stick together and that it is a way of telling the quality !

Bri

I can not find it but there is a web site with drawing corrections listed on it.

sorry I can not be more help

Bri

That's a great reply Dave thank you. I had a sneaky feeling they were the same process.

Bri

Is there a difference between annealing and normalizing?

this would be for any type of metal

i agree with 34046 Blow down valve. Ball missing from the seat.

RDG do really small ones cheap enough.

If your going to make your own you will have to source the glass and cut it to length?

Hi Mark

Yep all tig welded.

I am sure my boiler inspector will have something to say!

I made a start on the hydrostatic lubrication today.

New tanks made from 316stst.

Whilst i was at it i decided to draw up the parts to check they all fit.

I should have more control over the oil flow rate with this system. The original mechanical ones chuck out too much oil and the tanks on them are small.

Hi Mark. There is currently a milling spindle for sale on eBay. Search Boxford lathe and I am sure you will find it.

Bri

Yes too tired.

My bug bear once, was the tip being loose in the holder. It took me ages before i found it. Doh

Bri

Nice work on the boiler Nigel, I too am in the process of boiler building to replace a 5" 040 boiler.

Bri

Not lovers of cats then?

Look for Cute pdf and download the shareware version. You can then use Pdf’s to display your work

CAD. Without it i would not have moved forwards in my professional life. I Started with Turbocad then moved to Autocad after 15 years i moved to Solidworks.

Now 10 years in to it it would take some beating. But thats my preference.

I would also add that its one thing being able to use a CAD system but designing conceptually is another thing all together. Not all people can do it

Middle first and take a cut. If the nut will not go on loosen the middle one and tighten the outer ones equally until you get the correct setting.

Search Amazon for. Sharpening small tools. I found a book straightaway for a few quid.

B

Thats a pretty grim sharpening job

My preferred way is to get a good sharp point and then slightly grind the point off to leave about 1mm face to do the cutting.

There are guidelines for the clearance angles and rake etc.

The MAP series of workshop books are really useful and can be bought quite cheaply from usual sources.
