Surface grinder reassembly

I you cared to pop down to me in Gravesend I would do a quick evaluation of your plate. You could bring the table and I'd do that too.

thats a kind offer Pete and I may take you up on it. I’m actually off to the US tomorrow for 2 weeks then another 2 weeks on holiday. So my project is about to be delayed for a month, sadly. But once I’m back, I’ll be raring to get on with it.

I may try to pick up a comparator when in the US, I have an idea for a simplified repeat-o-meter thing.

“ the repeat-o-meter looks great, with the snag that the base needs to be surface ground (bit of a problem at the moment!)”

I’d be happy to surface grind it for you

Right, back from trip #1, off on trip #2 for 2 more weeks, so I’m thinking about my surface grinder project for when I get back from that.

while I’ve been away, a couple of things came in the post… I have a carbide scraper, which removes way more material than my vintage hardened scraper. And a 1/10,000” clock, which didn’t work of course but I seem to have fixed it. I’m now pretty convinced that my surface plate is within a few 10ths.

The question is, what should I get for the project? It a choice between:

1) bigger, new surface plate. The one I have is 18×12 and seems ok but it could be flatter. 800x600mm is the absolute max, and I don’t really know where I’d keep it.

2) camelback straight edge – but it would need scraping, so I’d have to rely on my existing surface plate for that.

The longest ways on the grinder are 34”. Then straight edges are either 24 or 36 inch. If I could I’d go for the smallest one that would work.

I am ok to invest in some kit as I have 2 mills and a lathe that would benefit in the longer term.

Any thoughts from an experienced person?

thanks

Steve
