Thanks fr the suggestions Michael. The letters are actually no solid - they are outline fonts and the impressions are only a mm or less wide... but keep ideas coming....

Reducing the depth to 3mm should work. The pressing is done with a thin layer of foam behind the vinyl, so quite flexible. But 3mm deep relief should be OK. We don't want to melt the vinyl on the...

Aluminium - any grade will be fine.

You may be right, Michael. I'll see what we can come up with. I have a few 10 deg D-bit cutters with a few thou flat on the end that may do it. Alternatively, I could reduce the draft angle to closer...

Anyone here interested in a project and/or a quote?
It's an almost 2D job but with draft. Its a flat hot press tool for a collaborative project for a small band of enthusiast....
Around 200x65mm...

Thanks Greg. Had a look at all your videos and posts.

I went there and had a look. Actually I bought a couple of micrometers too.... as you do....
There is a lot of specialised measuring equipment - but not a garage sale prices. Some very large...

Hi Greolt.
Thanks for the offer! What software do you use to drive your plasma?
Any photos of your setup? I'm actually contemplating building one for myself.... but it is down the list a bit.... :)

I haven't been able to find hacksaw blades thick enough. They need to be at least 2.5mm thick. I found strips of circular saw blades to work well, with a piece of tungsten carbide brazed on the end....

That is truly a ripper! Well spotted! Looking forward to it's reanimation....

Cheers
Joe

Hope 2021 will be less memorable but more exciting and enjoyable for you all!

Cheers
Joe

Our Subaru Brumby has front disks with the parking brake integrated in the caliper cylinders. They work on a coarse thread system to give the required force. Not sure if they are too small for your...

Sorry, they don't make anything like that any more.... I got the reply by the sales manager asking an old storeman.... so it might be decades old.

Hope you get home soon!
Please do find out and let us know which parts were replaced and how they did it!
Sounds like they replaced the long proximal screw and everything from there out.......

The answer is: wire swage blocks. That answer comes directly from Gothia, Sweden.... and they wish us a merry Christmas down-under!
Must need a special swage tool to roll the sides in and around the...

I've had the same issue several times. It seems related to time, not use....
I have considered several time to tape the back and then sew the ends together with some thick cotton or this steel braid...

Good to see the thread continuing, Phil!
The original wheel guard would have been a casting with a flange on it to allow for more clearance for the wheel. Someone in the past (before Greg) has cut...

Why don't you have the option of a welding helmet? I only ever use my welding helmet for OA welding! In "grinder" mode, so it doesn't flicker dark whenever I look up to the sky.... That's the perfect...

Looking good for a new start, Stu!

Cheers

CK Worldwide will post to Australia directly too. You just have to ask. They don't advertise that.

One last point, if I may:
DON'T try to make welding 'beads' like you would on thicker steel. Invariably, the steel ahead of your puddle gets too hot and you will melt a hole sooner or later - the...

I suspect it depends on when it was made.
Mine had plain bearings and I replaced them with angular contact bearings.
A friend near me has one that came with Deep groove ball bearings originally......

Yeah, that's the hard part - particularly as I'm getting older...
But if you cannot see the puddle, you can't get good results. At least not until you have welded for a few thousand hours....
I...

Sorry, yes, asking too much :)
You should not switch ANYTHING on the output of the VFD!
You can use the original switchgear to control the VFD but NOT the motor. That MUST stay connected directly...

Sorry Stu. It is actually designated TIG200....
And yes, I mean HF - we used to call it "pilot arc" because it starts the arc through a plasma channel formed by the high voltage - like a "pilot...

I ordered one last night. Let's see if I can find the English manual for it.....

That is very impressive, Steve!
I can't believe the price.
I think I'll order one for my Arboga 2-speed drill now.

Cheers
Joe

What did you end up with Stu?
I bought one recently too: an AIG 200T
AC-DC, pilot arc and very happy with it so far.
They were very good to deal with and have allowed me to modify the connector...

As far as I can tell, there is no adjustment. On mine neither....maybe they were just meant to be maintained regularly...

Cheers
Joe

Any updates?
Another engineering friend suggested tapping M7 into the hole and using a nut on a through-stud in my last tool design and make an adjustable backstop (grubscrews) for each of the pins....

Simon: yes, that is what they are. Radioactive nucleotides.

Cheers
Joe

Simon: I don't know the physics or chemistry, but pretty well everything within 100km of Chernobyl has significantly more radioactivity since the explosion. It's not a big deal if it's alpha or beta...

For anyone reading this thread, using Russian/Latvian titanium: see if you can find someone with a Geiger counter and take your titanium with you.
It turns out that enormous amounts of titanium have...

They certainly did. As did many 2-stroke manufacturers in the early 50s: Tornax, Puch, German Triumph, Victoria, NSU and others. I had and rode a Puch 250 2-cylinder single combustion chamber and a...

No worries Ian. First come first served. Them's the rules. Good luck with it and good on you for saving the drill from the smelter! A VFD should get it going again....

Ian: how about you take the radial arm drill and I'll get the MIG welder picked up?
I can see you asked first - just a compromise proposal.... [emoji849]

Just ran your issue by another member who lives near me. He asked if you couldn't just tap a thread into the now rounded hex hole?
Would that be an option? You might have run a drill or reamer into...

I agree! Why not make the tool, get the pins and hand them to them without any comments.... I'd love to see their faces....

Cheers
Joe

If you were to turn the very bottom end of the pin spanner in my drawing separately say 10 or 12mm long. In other words a disk with the locating pin and the two 2.5mm holes, you could use that as the...

I'd love the MIG welder. But I'm in Victoria....
Andrew (trail), would you be able to pick it up for me ad put it in a corner please until I can come and pick it up from you? It wont be until next...

or use a spotting drill directly. It would have to be a sharp 4-facet and probably cobalt (M42) or carbide.
I would hesitate centre punching too! It'd be worse than hitting your shinbone on a towbar...

PM sent re 6-pole motor.

Brazing would definitely melt soft solder in the vicinity!
Why not soft solder some brass wire pins to the dent and tug on those until you have the dent where you want it? It might take several lots...

How's this for an idea? Maybe you can use it to illustrate the idea.... or make one?
Obviously the dimensions are guessed based on your photos....
Submitted in good humor - I just like fiddling...

I guess it depends on what they are doing. My orthopod didn't want me to watch getting my hip replaced - although I asked to. He said " we generally do intrathecal but put the patient to sleep. It...

Hi Steve,
just another thought - not engineering related.
You mentioned that you had to get a general anaesthetic for every procedure. I don't know how 'squeamy' you are, but I've had a fair few...

Hi Steve,
Oh my god! I see what they have done... They must have used a huge amount of force to shear ALL the corners off the internal hex to get it to round like this....
What a bugger! You have...

They were very common in Germany in my childhood and youth. I've driven quite a few of them that were "student cars". They were 3-cylinder 2 strokes - the last one about 90Hp and they went very well....
