now all you hear over on this side of the pond are the Delta or DeWalts . The better US saws are the Porter and monarch unipoint But the best vintage every made has to the from Thomas White in Scotland .
like joe's saw though these are not RAS there what are callled straight line cross cuts saw . bearing cartage are way wider at least 3 time as wide as a RAS cartage .
White also made a swing type saw (seen German makers with the same ) but with a back arm to keep the blade level with the table for trenching cuts
Stenner made a good saw to with the pivot point right over the fence slit and a dust shoot under the table
as was said the Unipoint is the best american saw but is not a RAS as you can see
many of the big old clunkers are just not capable of the operation of the typical RAS and can not configure in as many arrangement . This is what the Dewalt is know for. As these saw were around before the claim that they were invented by Dewalt .
and one for Darcy
now i think that all the bad about the old saws is there old and knackered . some like the Delta can be brought back by part replacement but the old dewalts with all those bearing most likely need the arm re-machined to get them up to sniff. the old Delts when rebuilt do cut clean and accurate work
