Topic tags/keywords: rockwell delta 14 bandsaw 28-380 motor replace rebuild restore question tip resource

This saw is a recent purchase from Craigslist and everything on it works properly. I go this saw to use for cutting bowl blanks from logs and perhaps some re-sawing and also in my construction of Cigar Box Guitars.

I am looking to add a riser kit to increase the depth of cut and add some type of rip fence system. Any suggestions on these would be GREAT

BUT…. MOST important

It seems to have a lack of power on the wood cutting setting (this is wood-metal cutting combo saw) It seems to run slower than my new 9” bandsaw and bogs down if you put any good size limb or log in it.
I just installed a NEW 1\2 blade and set tracking and all guides before starting this

PLEASE advise and also if I need to up the HORSEPOWER any motor suggestions and motor speeds (this one is 1750 and seems SLOW) also pulley sizes to gais power and or speed

I love the look and amazed it runs so well over-all being a 1965 model. I’m a 65 model too and I dont run this well LOL

Manual for the old Deltas recommend a 1/3hp motor for normal use, and 1/2hp for working with thick/heavy material or when using a riser block. The newer manual (which is applicable to your machine) just recommends a 1/2hp regardless. I have a 1/2hp on mine (1950 wood only model) and have never had a problem. The blade is the most important part. Many people just throw more horsepower at them to compensate for other issues. The motor should be a 1750 (1800) RPM deal, and the blade should be running, for wood, somewhere between 2200 and 3000 SFPM. I would give the machine a good once over to make sure it’s not having other issues, like a slipping belt, bad bearings or partially engaged gear box. You can use the SFPM calculator over at the VM site to calculate what you have based on the pulleys being used.

Here is the manual for your saw:
No. 28-290 & No. 28-380 14 inch Wood and Metal-Wood Cutting Band Saw PM-1827

And in case you haven’t already watched it, here is the obligatory band saw tune up video.

PS: Changing out the bearings (including the motor) would be a good idea regardless… you have no idea what use/abuse they have seen, it’s pretty easy to do, and is cheap insurance against future, potentially much more costly damage.

Thank you for the info. I have a manual I printed out but I am gonna check your links to see if this is any better information.
Any idea how I can check the speed of the blade? I have the original motor on it and I blew out with air hose all the dust and junk I could and it has the original pulleys on the drive system. I checked after getting a new shorter belt and the gear box works and the blade spins MUCH slower using the gearbox. I plan to drain and replace the oil in the gearbox and I have installed a new blade and reset all of the guides. I have cut a couple of smaller 1×2 and such with out trouble altho slower than my cheap WEN 9” bandsaw but I put an approx 3-4 inch “log” or limb and just attempted to cross cut the end and it bogged the saw down completely and I wasn’t “pushing” or trying to saw fast. I have a 1/2 inch 4 tpi blade on it now

I agre that especially in America we want more and more of everything BUT….I hae seen people using this type saw in online video demonstrations and it is much more capable than mine is currently.
I need to cut bowl blanks and do some re-sawing and I want to purchase and install a riser kit to allow for bigger material but It bogs down on things my small WEN 9” saw would cut. Theonly thing I havent done is replace the oil in the transfer case. I have cleaned and lubricated everything and installed new blades and gone thru entire setup process and it just seems weak and under powered. I love the solid way this is built and I know I will get her humming but I am looking for advice from experience. I hope someone has been here done that and can offer more ideas or upgrade suggestions
