    Top section is split to half, then bend, interior sides plated with 1.5mm thick stainless 316 steel plates. Surfaces sanded and polished. Then these halfs are weld to the end of another piece of rr-track. Welds are grinded down to look like original surface on the track.

    Thats a really clever design!

    There's alot of quality art out there that I really don't appreciate but I do enjoy functional art and yours is a top example!

    Nice.

    Remind me never to get into a scrap with you Tuomas, — if you can swing an axe like that, I'd have no chance. Very nice work and thank you for sharing with us.

    Thanks!

    That axe was found with a metal detector, from the battle area of Winter war. ( FIN vs Soviet union in 1939 ) Stamp on it says that its made by Billnäs before 1920 )

    Its at the same condition as it was when found, just cleaned and oiled. Its clamped on its place with small splines. So it can be removed without leaving any marks.

    I tought, that way it stays stored and will be seen, when it has another reason to be visible, instead of being just an axe blade on the shelf.

    Drilling the finished hole right through instead of the tapping sized hole is something I've done countless times.

    Never ceases to amaze me how I can sometimes do intricate and tight tollerance work, only to be stuffed up with a seemingly simple operation done wrong!

    Simon, most of us will admit to doing the same thing. After I wasted an expensive billet of Aluminium, doing that, I decided to always drill the tapping size first and then the clearance hole, so far so good.

    Default Boring Head attachment

    Hi All,
    A few day's ago I watched a youtube video posted by "outsidescrewball". Chuck has been making a few different versions of an attachment to fit on his 2" boring head to make it a lot easier to hit the correct dimension. I could see that this would be a very handy tool to have. My boring head is a 75mm one so I took it out and worked out the dimensions I would need to make one. My head did not have enough surface area immediately above the diameter adjusting screw for the point of the dial indicator to touch on. I decided to run the indicator point on the main shank of the head some 8mm higher,using this location also gives you a bit more room to access the adjusting screw.
    After finishing all the machine work I used some Birchwood Casey Super Blue to achieve a machine tool finish, this did not turn out very well. I ended up with blotchy finish as you can see in the pictures even after three applications. The attachment works very well and gives you far greater control and you can make very small adjustments, if you do overshoot your mark you can reset back easily and try again. A big thanks to Chuck for the design.
    Bob

    Thanks for posting your project Bob, it looks a nice piece of kit. I have no experience in Blueing operations, but from what I have read, the better the surface finish and the cleaner it is, the better your blueing is likely to come out. That said, it will work perfectly the way it is, and your blueing will help protect the finish as long as you have applies some oil to it.
    I like Chuck too, probably should watch more of his videos, he may not be the technical nerd that Tom Lipton is, but he does interesting stuff and is very personable, (as is Tom of course).

    Is this removed after setting your depth of cut?

    Pity about the bluing Bob - If you were closer I would have offered to put it in my next batch of cold fume bluing.
    Other that that, nice job.

    Thanks for the response to my post. Now to answer the questions. Pipeclay Yes the adjuster is removed after making the adjustment, the dial gauge only makes the movements many times larger and in doing so makes the boring head a more precise tool.BobL Thanks for the offer on the blueing I have been following your excellent results, but we are located worlds away. I did follow the instructions on the bottle and the original finish on the parts was almost a mirror finish.I think the blueing liquid may have been too old.

    Default Your latest project

    I’ve been using the Caswell black oxide solution. In my experience patchy colour is always from the parts not being clean enough.

    Wiping with a solvent such as Acetone on its own doesn’t get it clean enough.

    I haven’t got too serious about finding a good cleaning solution but find that soaking in a alkaline cleaner (I use diluted chemtech CT18 truck wash) and a rub with scotchbrite, followed by water rinse and blow dry works reasonably.

    If it still looks like it’s coming out patchy I rub it all over with scotchbrite while in the black oxide solution, leave it for a bit and then repeat the scotchbrite if necessary.
    I did notice that the solution started to weaken after about 6 months of using the same 1L mixed batch on and off, and more scotchbrite rubbing was required until I got sick of doing that and changed the solution.

    Steve
