I have a powr-kraft radial arm saw without a table or rails. It’s just the base. I have a pretty good idea how to build the top according to the Mr. Sawdust plan, but I don’t know what mechanism to use to adjust the height. In other words how to I raise and lower the different corners?

Take a look at http://eberhardt.bz/GME_Wood_Land/GME_Woodworking_Stuff/2_Tool_Tune_Ups/7_Tuneup_Radial.pdf
I think section 4 is what you’re looking to do to get your table level.

Shims? That’s way too simple of a solution… I think I’ll do it. Also, how is your table doing patron? I saw that used you used the single layer of 3/4” particle board, has it started sagging? What is underneath it? I really like the way you did yours but I’m concerned if I do the same thing it may not last, then again I can replace for 40 bucks right? Thanks for the links Nicky.

Not sure how much space should go between my fence and the column.

When I used a RAS a lot I would nail a piece of 1/2” ply to the particleboard
table, which kept the table from getting carved up. Some people just
dial the saw in to cut 90 degrees and use jigs to cut angles. Radial arm
saws are notorious for not going back to square after you move the
arm.

I plan to leave the arm at 90 and use jigs.

in response to your PM ww

my stand is just a cab with a divider in it
the saw set on top screwed down to it

and spacers run up to hold the saw top
(this is what is ‘shimmed’ by ‘tweaking’ them
up and down from front to back)

the back has a spacer too
to ride the top on
and the fence screwed down to it
to keep it flat

i got the saw arm as square as i could
any further adjustments were in the fence itself

the right wing was in my way
to move around the workbench
so i cut it and just hinged it
and hold it up with a ‘temporary’ leg

i think this is what archimedes was thinking about
when he said
‘eureka i have found it’

but since they didn’t have particleboard in his day
he quit and found a way to lift water instead

I wouldn’t fuss overly. A RAS is a real workhorse for chopping up long heavy boards to rough length but you could make a career out of trying to dial it in perfectly.

i don’t know about that MC

i had three dewalts in my building interiors business
all with 8’ tables
we ripped and crosscut every thing in the interiors

set them up square
and never moved the arm
didn’t matter which my five carpenters used
they all cut perfect
take the top off and load them in the van
for the next job

radial arm saws have a bad rep
from being used on job sites by rushing carpenters
and often were set up outside on uneven ground
with nothing more than the top that came with them
and everyone making sloppy cuts with little or no outboard support
the tables and fence got so beat up they were dangerous

this was all before chopsaws
now days everyone (almost) doesn’t like them
but like any shop tool
set-up right and used responsibly
they are just as good as any tool

i use sleds on the table saw
a chop saw
and the radial arm saw
every cut is square
makes no difference
and less down time for me
