I have a 14-inch Walker Turner band saw for cutting metal and wood and I have a problem with it which is the reason for this message.
This band saw is a recent acquisition, was rebuilt by me and has been used only in wood and at the lowest speed without the use of the gearbox.
There is a part connecting the 4-step pulley at the saw side to the shaft through a spring-loaded pin. This part is held in place on the shaft by two 5/16”-18 grub screws mating with two flats in the shaft. The flats were originally mangled, the screws had slipped in the shaft scoring it; I removed the ridges and reworked the flats in the mill but the part keeps on becoming loose. No amount of thightening will make it stay in place. There´s what feels like adequate free play between the pin, the part and the pulley when rotating 360 degree by hand, I made a new pin and a steel part inserted in the pulley for the pin to sit in when connected, there´s what I believe to be the original non-steel washer between the part and the pulley and everything is kept properly lubricated.
So, the problem is this part becoming loose after 15 minutes of use.
I’ve tried the Vintage Machinery website, also postings in YouTube about Walker Turner band saws but found nothing useful. I got an exploded view of the saw from the Vintage Machinery place and all the parts are there.
I´m attaching a photo of the troubled part.
Has anyone had this problem ? does anyone have any ideas that would help?
Best regards and thanks for your attention.
