Thread: Your latest project

Hi

I restored Soviet SVT-38 bayonet. And wanted to make a little different stand for it.
I used 200mm long piece of 159mm high ( 54kg/m) piece of railroad rail and oak. It was a gift for my brother in law.

I can't get anything that sharp... 😢

Well done I like that very much.drooling.jpg
How did you do it?

I stamped with press a set of simple tealight holders for My wife.

The tealight holders look really nice Tuomas. Did you make the die up yourself ?.

Thanks. Yes. I made / modified them from the material i found.

First from the left guides pipe to be stamped straight.
In the middle, is the one that makes the actual " mushroom " shape. Cone in right, is used to shape the bottom.

Shape is made with die grinder and angle grinder.
Originally it was threaded axle, i weld couple nuts to it and shaped it after that. That way i got straight area to the bottom part, where to grind that curved section with die grinder.

Tool looks little rough. But it works nicely.

And, yes. It seems that i forgot to mention that those are stamped from 65mm long pieces of 44,2mm pipe with 1.6mm wall.

1) Machining up fake nail heads, because blacksmithing them failed:

First time grinding a HSS profile cutter!


2) Sharpening an old circular saw blade:

because I haven't yet created an adapter/sleeve/arbor for fitting modern sized blades to this saw.


3) Polishing the rust off (the arms of) an old mag base that someone gave me:

4) Cleaned up an old 2ft ruler. I wonder if this "Chesterman, in Sheffield" became Rabone-Chesterman?

Nice work! That looks handy. I have made a ball turning tool, but its quite complicated and slow to use. Didn't get any profile cutters work proberly.

It's a good illusion.
It looks like a slab was sawn from the top of the rail and bent.
Then the mating faces were polished before gluing back together.

Nearly. Its made with the same way than this:

Here is another version. Its left outside to get natural rust to the rail.

Its cut, bent, plated with stainless 316 sheets, sand/polished
then weld pieces together.

Here temperature can go -30 degrees of celsius in winter time.
Its important to weld plates airtight, otherwise water between plates freezes and cracks them out.

You want to see slow? Try approximating a ball smoothly with a DRO
21mm radius @ 0.5mm step = 66 discrete sets of co-ordinates:

My eyes got sore from staring at the numbers, while cranking the cross+carriage feed handles to zero them.

Didn't get any profile cutters work proberly.

That cutter was ground from 12mm or 1/2" HSS, and was hacking into 16mm diameter black steel rod (mild). When it was freshly ground, I could only just use it on the Hercus without judder. After a while, it lost its edge, and the toolpost/slide/saddle bounce became an issue.

So, I had to throw it on a bigger lathe (Hafco AL-336). It got through 20 or so, before enough steel built up on the edge that the steel was tearing in places. (And that was with coolant!)

Thus began the continuing cycle of taking the HSS out of the holder, giving it a lick on the lathe, cutting a few profiles, noticing that the shape isn't perfect, taking it out again, smoothly grinding around the high points, et c.

I eventually got a flat enough raked top that a quick polish with a diamond dressing file did the trick without having to regrind. But I'm sure it will need another trip to the grinding wheel soon. Maybe after another 50 or so profiles?

Hi Nigel, Guys,

This is where I would have used a carbide wood work router bit !

This picture is from when I made my Norman tool post.

The cutter is held in a piece of square bar held in the toolpost, drilled 1/4" to accept the cutter shank and then slit lengthwise. Once adjusted for a degree or two of rake and set dead on centre height, it makes a good job of turning a radius. I've made curved edges the same way on the mill with a carbide router cutter.

The oiler thread

Got me thinking, mainly about how to get a decent tank on one that would not cost a fortune in brass.

During the week I thought about how to get some sheet metal involved. This is of 1.2mm Al.

Cylinder is 50mm diameter, around 125mm high and would hold around 200 to 300ml of fluid. Feels nice in the hand and the flared base gives it a bit of stability. I thought the Al might be a bit soft, but it is firm enough that I'm thinking of turning it to use rather than just as a demo piece. Future versions will probably be of 1mm steel as I have more of that and the welding might be a bit easier.

Not wishing to interfere with another similar thread on this forum, I post this separately....

My recently completed project for an improved stand & tray for a small bandsaw, as below;-

I may add a coolant system, though I'm not a fan of water-based coolants up here in the tropics due previous corrosion issues on other machines. (Just use a kero/oil mix or WD40 as a rule). At least this way the metal debris is in one easily cleaned area & not all over the machine & surrounding floor. Design inspired from other contributors to this forum & other internet - sourced ideas.
Very stable to move around & use. I have taken care to keep the large wheels outside the centre of gravity when the head is tilted vertically; having had the usual scares with the original poorly balanced stand, which I had previously modified anyway.
The machine is about 100mm higher than standard. Easy to clean due to the stand-offs. The tray (850 x 330mm) is mounted off centre about 30mm to favour the cutting side.

Regards
Halifax
