I have followed the advice given to me here and bought a Meddings MB4
7/8 inch bench drill - and I am very pleased with its condition and
capability (and price) given it dates back to 1964. But I am going to
ask a really dumb question - you see they never did metalwork at my
school !
How do I best hold the work ?
This drill has just the bench base-plate, no intermediate plate. The
base-plate has two big parallel t-slots 175mm apart. I have a couple of
drill vices but nothing that size. I have been using my lathe to do any
half-precision drilling up to now, and that means the work is well
clamped to the vertical slide, but what do I need for this drill ?
Should I be looking for a big drill vice, or maybe a compound slide so
that I have more options for nailing down tricky bits for drilling ? As
I have to drill against the base-plate I can't use G-clamps.
I am sure there is loads of experience out there, so what do you guys
use ?
Thanks
Steve

Steve,it looks like you are missing the table.Hard to find,I had a
brand new one and gave it away.An x,y table might be your best bet in
the circumstances with a decent vice bolted to it.At 7/8" capacity I
would just hold the vice by hand,but I`ve been drilling holes for forty
years and you haven`t so I wouldn`t recommend it.
Mark.

Where are you, & what dia. is the column?
I've got a very scruffy Progress drill stand & table sitting outside
in the weather, you're welcome to the table if it's of any use.

Thanks for the ideas
Mark
This one never had an intermediate table, I called Meddings who were
very helpful and identified the model as MB4HRM. Its a 2 3/4inch by 3
foot solid column and has a clamp with a worm and rack which can be
used to move the head up and down. That kind of blocks adding an
intermediate table, unless I junk the head raising mechanism (HRM), as
the rack is next to the column.
I thought about using the vice loose and then wondered about that
moment when it bit in something thin and went around. An X-Y table
sounds a good option, and they don't seem too expensive. I wondered
about using magnetic blocks either to locate the drill vice, or one of
those magnetic surface grinder plates to hold the vice down - though
they seem rather pricey. I suppose the swarf sticks to everything and
you end up in a right mess. Also it just occurred to me that I could
drill and tap the base table - I could use the drill itself to do one
either side - maybe thats all I need for now.
Tim,
I'm in Chester - I'll have to come over and say hello sometime. Don't
think you are very far away.
