Thread: Your latest project

It is around 55mm thick... It turned out whatever the piece of bar I had was...

I bought this vintage concrete mixer a few weeks ago - I've been mixing manually in a wheelbarrow and it's nearly killed me . The old machine has a Petter A1VO 3hp motor of late 1940's era. The Petter runs happily on today's unleaded petrol but it will run on power kero too. The "VO" for vapourizing oil , indicates it has the manifold fuel heater fitted . The magneto is a WICO . The wheels are Ford Prefect 16" . I didn't tow it home BTW Certainly has made the concreting a more pleasant task

A nice couple of old units there. Looks like the old Landy is about the same vintage.

Yes the rover is a 1950 model with the weird 4 wheel drive system, basically its in full time 4wheel drive , there is a free wheeling clutch at the front output of thetransfer box . The idea was , the clutch grabbed and drove the front axle under certain conditions eg, when the car is in mud . You could lock the drive in 4x4 for reversing by pulling on a chain on the floor . Rover dumped the idea for a conventional system in 1951 ?

BTW Rover cars had the same free wheeling drive , you pulled a lever on the dash for free wheeling down hills . Another strange British thing

Nothing too taxing here. A couple of hours work. I want to get some video of a mate's kart on my tail with the GoPro mounted on the rear bumper bar. The GoPro handlebar mounting kit is a flimsy piece of plastic. No way would it survive the vibration and pounding of a go kart. I'll add a safety lanyard in case the plastic tripod mount lets go.

That looks great Jack, do we get to see the video action? I sure hope so
Rob.

We're taking the karts out tomorrow Rob. I'll post a couple of stills.

Thanks Jack, I will be on the road tomorrow and may not be able to see it for a day or three, but I look forward to viewing the action. Hopefully it will be exciting but not too exciting, with all the wheels pointing the right way and sticking to the black stuff

SWMBO need a spare car key so I though I would have a go....
Took a photo of the key drop it into the cad program, getting the scale was most important here.
Cut some blanks out of brass, then set up for key cutting, had to do both sides.
Cut out the wood handle so the inside would fit over the keys and then glued a bit of sanding a touch of clear ...done

Think I could have done better shape for the wood, made it bit more sexy,,,next time.

Now I just have to wait till she is back to see if there work...

As I mentioned in a thread a little while ago, Ive been working on a ER40 Collet Chuck for my Hercus 260. I finally knocked it over today, works a treat!

A lot of people go with the wisdom of buying the nut rather than making it. While Ill admit it does have a few challenges to cover in its machining, its by no means impossible. I started with the chuck body and the female thread of the chuck. I mounted the chuck body on the lathe and then the nut on the chuck body, using a ring (ID 50.5, OD 65 and 8mm thick) to hold the nut up against the threaded section of the body. From there I was able to do the remainder of the outside machining as well as the front tapered section. Then I mounted the nut into a 4 jaw chuck to machine the eccentric ring. The front taper is probably the hairiest bit, but I use a boring bar with HSS ground to a pretty fine angle and it came away pretty nicely (which you can see in one of the photos).

And in use, what a rigid thing it is! I machined a bit of 20mm 1020 and I was able to do a 10mm DoC. Now Ive just gotta buy a range of collets and Im laughing.

Thanks to WCD for those dimensions, they were spot on

Wow,

It has taken me at least 3 viewings to understand all the steps.
There is a lot hidden in those few lines of text.
How did you make a start with the CAD?
Having just lost a set of keys I can see the advantge in having a unique style when describing them to the police at the local!

Thanks for sharing

Having a bit of a stab in the dark, but Im guessing he took a photo and then converted it to .dxf through a software converter. Its neat work though, the keys look fantastic...I just hope the car doesnt require a key with an RFID chip in the key - might want to test it before you depend on those keys rusel!

Well done ,could you run through the process you used and what software

Hi
To answer your questions
Yes there do open the door...
Software was Rhino and rhinocam and yes photo was taken of key then dropped in as back ground and then traced in large size, then scaled to size. CAM software was used for creating the cut program for the CNC mill.
The main point of this key was for when she goes swimming as she take the minimum stuff with her in to the pool as she is worried that it might get pinched. This way there can not just push a button to identify the car and now the key does not even have the car logo on it. As for starting the car I just try it as scottyd suggested it does not start the engine.This will make it even harder to pinch.
