I got one as a crab clamp off ebay last year but haven't found any since.
|Thread: New Blocks on the Block|
As far as I can tell the head dia on 1/4 UNC/UNF cap heads is .375" and a M6 is 10mm about .393". I know many claim size matters, but does a18 thou (0.5mm) difference make much difference?
So I cant see anyone making then in imperial sizes.
The choice of clearance whole size is down to the designer, it can be as close as you want with the proviso that the location of any holes has to be more accurate,
Why would anyone design a revised / new product to us a screw that has been obsolete for 30 years or more (BSF).
They look good to me as all of Johns other products for Arc-Euro do, Ordered mine as soon as they were flagged here.
|Thread: what does this mean on a drawing|
I believe that Dormer and presto are normally H7 inline with the Din standard.
This page also tells you the tolerance on the reamer.
and here-for Dormer
6H7 means 6mm tole tolerance H7
This can be looked up here
Column down Left hand side is tol class H6 H7 etc actual tolerance changes with size so look across top and find range in 3-6 so tolerance is -0 + 8 um ie 6.000 to 6.008
ON the LK ref is the PCR or PCD 17mm?
|Thread: How NOT to tap a hole|
Just like using a battery drill, ok down to M3 / 6BA.
WD40 is fine for Aluminium , have used spit when on a site visit and nothing else available, 1st choice is tapmatic, don't like the gooey pastes such as Trefallux anymore.
|Thread: My Super-7 trips out|
Have you got, or know someone who might have access to a clip on ammeter to measure the motor current?
Is the overload a 3 phase one used on single phase? If so are all 3 overload circuits wired in series to stop nuisance tripping due to unbalanced coil loads.
