I have been on the hunt for a variable speed band saw for many months, either a Powermatic 87 or Delta 28-365 machine. I missed out on a nice looking Powermatic 87 with the factory blade welder a few months ago, the price was $1450.
I found the Delta 28-365 in Costa Mesa last Friday, the machine hadn’t ran in a few years, 3 in fact. We powered the machine and low and high gears both worked, and the variable speed seemed to be in good shape. So I decided to purchase it, I paid $1400 with 4 blades, all wood cutting.
I got the machine home and unloaded it with a friend, should have got a fork lift because this thing is heavy.
Gave it a quick cleaning and lubing, I also realized the belt tensioner should be re-engineered, not the greatest from the factory.
After watching some videos on tracking and installing the blade, I took a shot. I got the blades teeth as close to the center of the wheel. But I was having trouble keeping the blade on the wheel, machine would pitch it after running for a few minutes.
After talking to a friend who owns a band saw, he told me about the crown that is required on the tire. I put a square against the tires, and they are definitely flat, and also very cracked and beat up.
So I dag a little deeper and realized the band saw was equipped with the incorrect tires, this machine is equipped with a groove to accept an expensive t-groove tire. I ordered a set of “economy” tires from Sulfur Groove Tool, they should be here tomorrow.
In the mean time I have been cleaning old rubber cement, anyone have a trick? I have been using a heat gun, scraper, and wire wheel….
Would flat tired tires cause my problem? After watching Mr. Wandels video on crowned pulleys it makes sense.
Also, does anyone make a good fence for the 24” table band saws? The Kreg seems much to small.
