View Full Version : Where to get a small magnetic chuck?

04-21-2011, 12:37 AM
As you do, I've occasionally found that an ability to grind (hardened) parts would be handy. The jury is still out whether I should try and find a surface grinder or make/ buy a T&C grinder that I can attach a magnetic chuck to. Typically the sort of parts I want to grind are spacers etc, so parts would normally not be bigger than say 2" square.
However, looking around I haven't seen many small magnetic chucks. 5" by 7" seemed to be the smallest I've seen around. Has anyone seen narrower? Most T&C grinders are not very wide so something 4" or even 3" might be more appropriate.

There is one that is sold regularly on ebay from a seller in Tasmania...

$200 for a 4 X 8 size... I think it a bit expensive given our very high $ at the moment $1.07 and still rising...

I recently completed a T&C grinder and bought the CDCO 4x4" chuck.

http://www.cdcotools.com/index.php (Item # 27202) It is quite cheap but I figure I would be doing jobs as you describe - not full blown surface grinding.

It is well made and has a reasonably low profile which was important on my machine. I am impressed by the holding power but have no experience in this field.

Here's on that's 3X5 and less than 2 inches high.

Yes, it did. The Executive on the Club have seen it!.

I will post some shots soon.

You might find something here. Even a round chuck may do the job.

I bought a used 6x18 Brown and Sharp chuck for $125. It came with a free and working 70 year old 6x18 Covel Grinder attached ;) After using the lathe to make the necessary wheel spacers, the whole thing turned out to be a great deal.

I'd love a proper surface grinder but space is limited. I have a spot on a bench top that I can spare but it's only around 600mm square and I'd prefer not to have large amounts of overhang - hence the thoughts of using a small T&C grinder for those odd jobs. Most of those that I see have a cast iron base. Easily detached so the grinder can be used on a bench top but then what to do with the base? Removing parts from a complete machine just because I don't want them doesn't sit right. Perhaps fabrication is the way to go.
The 3x5 from Gromax would be ideal for me, except for the pricing.
