The TEFC motor is internally cooled and made for this application.Ī link belt will help reduce vibration (Fenner PowerTwist ) Solid cast-iron sheaves on the motor & the saw arbor also help (Browning )īelt drive saws have a limited amount of clearance between the saw arbor & the underside of the table - most use a sheave that's about 3" diameter. The reason is that the ODP motor self-destructs when used in table-saw service - the sawdust gets sucked right into the windings. Be sure to get a TEFC-motor instead of an open drip-proof (ODP). Two to three HP is a good size for the motor on that saw.
#Delta rockwell table saw arbor bearings how to
One question is what size pulley to get for the new motor? Not really sure what sort of cutting speed would be ideal.Īny thoughts on how to find out what model i've got, or on pulley size/cutting speed would be much appreciated. It is a belt drive, and the craftsman of the same era at the yard sale had an old 1/3hp 3450 rpm motor on it, so I was thinking I'd go for the same. though they seem to be running pretty well, and then reassemble, and get a motor for it. My plan is to clean up the rust, possibly replace the main ball bearings. It's castings have some markings, but as far as I can tell there is no model number or anything. It has a cast iron table and wings and looks like it might be from the 60's. It is a small model (which is good for me) Looks like it might only take an 8" blade.
I was out yard saleing last weekend and was able to pick up an old Rockwell/Delta table saw for $20! It's been sitting for a while and it's not working, but it looks entirely restorable and should be a hell of a lot better than the old ryobi hand-me-down tablesaw i've got right now.
