I've always used an adapted screwdriver to access the slot on a Willis and Bates NRV but I've never been entirely happy with this solution so I decided to make myself a special tool. I saw someone use an old flat bit for the blade so having a bunch of duplicates I set about grinding the point off the tip. Having done that I needed a cross piece but all I had was some 12mm threaded bar but it had to do. I drilled a 7mm hole in the threaded bar, cleaned the surfaces, applied flux and soldered them together. Admittedly, solder wasn't the ideal choice but I figured it should hold ok Here's the result... I'll admit, it's not pretty but it does the trick!
@ColinG It looks the bee’s knees, it’ll do the job, just one question...... Did you silver solder the tee piece on, or was it lead/tin type solder? Cheers Pete
It was soft solder only, Pete as I'm short on silver solder and it's blooming expensive! Hopefully soft solder will do the trick but if there's any movement I'll drill and pin it.
Nicely done colin, there could well be a few more variations made by members here now the seed has been sown, I might even have a go myself. Regards Ian.
I really need to stock up on various sizes of steel stock, both rod and bar. There are numerous small projects I can't get on with because I don't have the right materials.
Besides working as an NRV tool, I think that's the kind of device that might just get a surprising amount of other job's done.
@ColinG A good idea Colin. If you sharpen the tip of the drill, it will always be centered. See photo. Tom
I had thought idea of that but decided against it although I can't remember why! I might regrind the tip and add a small point this time.
