Honestly, after you get only slightly more experienced, you won't want
to be struggling with some compromised Half-Answer for a table saw.
There are dozens for sale on Craig List for $100 or less. Look for cast
irn table and side extensions. I just got one for my retired father for
$50 in perfect condition, hardly used with accessories. Found him a
radial arm last ear for $50. And before somebody starts steering you
into an expensive Delta or other multi-thousand $$ overkill, I'll tell
you that I am a professional woodworker as my sole source of income for
nearly 30 yrs and have a Craftsman in my own home shop. You can make
these (see below) wheels for your saw fast and cheap so it will be
portable. Use at least 3" wheels. The wheel kit they sell has tiny
little things that don't roll or steer easily, especially if there is
any debris on the floor.
