Between Centres Grinding Fixture
« on: January 14, 2025, 06:23:51 AM »
Slightly rude of me that I've been a member on this group for ermmm...11 years, and yet this is my first post. In my defence, I had a lot going on in my life back in 2014/15 and lost a huge amount of enthusiasm for these things.
I recognise some names on here from other forums and the old uk.rec.models.engineering newsgroup, glad to see that some of you are still around.

Anyway, little project that I did last year. Posted the entire build story over on the HSM site but I thought I'd share it here too.
I have a surface grinder (J&S540) but needed to grind some cylindrical stuff, so made up this fixture that fits on the mag chuck.
It will take 9"/225mm between centres, with a centre height of just under 3"/75mm, and has a workspiece speed of around 260rpm.
The rear centre is spring loaded and moveable via a thumb lever, and the rear centre block has a flexure for taking out taper.
It was fun to design and make, and works very well.

Nice job :-)

(And a reminder to me to get on with my aging grinder project)
