    Walker Turner Bandsaw

    New to the forum, new to walker turner bandsaw restoration. Looking to shoot a video on restoring a Walker turner bandsaw but trying to figure out what saw I am dealing with here and what blades rubber and bearings etc are needed. This thing has no identifying serial number or otherwise notification on how I can figure out what models and dimension to be addressing... Thoughts? I appreciate the help and hope to grow my presence here. Thank you all!

    Re: Walker Turner Bandsaw

    Welcome to the site. Always good to see old machines being tuned up. I'm sure someone will chime in with information regarding your saw. Looks like a solid piece.

    Congratulations on the saw, I love old iron.
    The bearings are standard sizes and you should be able to find them at any bearing supply house or flea bay.
    Measure your tires and there is a host of aftermarket manufactures selling tires on flea bay.
    If you need to fix up your guides Carter makes a very nice set.
    IRRC Walker Turner was acquired by Rockwell Delta back in the early 50s and Rockwell continued to manufacture and sell them for a while.
    So having said that some old Rockwell saw parts might fit.

    Re: Walker Turner Bandsaw

    You might want to check out the OWWM.org (I think that's right) website - they have a lot of info on old woodworking machines.

    Re: Walker Turner Bandsaw

    Thank you all for the welcome!

    What's an ideal way to measure those tires and bearings assuming there is no demarcation? Should I just cut the existing blade in half and measure one side to the other?

    As for the owwm site it is helpful except that none of the info on it can be sure to pertain to my machine since there is no for sure markings telling me what year etc... I think this machine is pre serial number.

    Re: Walker Turner Bandsaw

    If it were me I would measure the diameter of your wheels and it looks like you have two different sizes and order from ebay.
    The bearings should have a number stamped on them.If not Allied bearing in Nashville or any other local shop should be able to help you.
    Good article to help with your saw.https://www.popularwoodworking.com/a...g/tune-bandsaw

    Re: Walker Turner Bandsaw

    Looks to me to be a BN730, probably from the 1940s.

    http://vintagemachinery.org/pubs/808/2253.pdf

    The lower wheel is likely on a tapered shaft. The upper is a slip-on, or at least it was when new.
    The tires are 12" size, so that means they will be 20% under size so they can be stretched on. The tires will have to be crowned after installation.
    It makes a nice band saw and worthy of the effort required for restoration.

    Re: Walker Turner Bandsaw

    Bob thank you for your input! I went out and disassembled it and measured the blade and wheels, definitely 12" wheels. Blade appears to be 78". I have all bearings pulled and ready to order as well as a new cord. I am looking to see if I can find an upper shaft replacement now, when I took out the retaining nut and washer the threads look a bit knurled so if I can find one id rather just replace while it is apart... otherwise everything looks great.

    Any ideas if anyone has a step pulley assembly that could be put on to make this thing have adjustable speed?

    I am loading up your links to check them out right now!

    Adjust the speed for what purpose? That saw was made for wood cutting. To get a steel cutting speed, there's going to have to be a roughly a 10:1 ratio in speed reduction. That gets awkward with pulleys. A dedicated gear motor would be your best bet there and those things get rather pricey.

    The original specs call for 2,000 feet per minute or 670 rpm of the lower wheel.( That math isn't perfect, but close enough) That would be a 6-1/2" pulley on the lower shaft and a 2-1/2" pulley on the 1740 rpm motor. To get 200 FPM or 64 RPM, you'll need about a 22" diameter pulley and thus the awkwardness.

    Re: Walker Turner Bandsaw

    The short version is to get the bearing numbers and give Lynne Scott at Accurate bearing a call. Nachi or equal are a good medium quality bearing brand perfectly suitable to this application.

    One of the links above seem to indicate the bearing sizes are 6203LL and 6202-5/8 LL (LL means a sealed bearing rather than a shielded one) The cost should be less than $20.00 including shipping.

    Re: Walker Turner Bandsaw

    Just to put things in perspective, the BN730in 1939 listed for $35.00. The optional stand was $9.35 and the optional 1/3 HP motor was $13.95 and a switch was $2.50. Total in 1939 dollars would be $60.80. Adjusted for inflation, that's $1071.90 in 2017 dollars. What that reflects is mostly the quality level of a 12" band saw you can be building for yourself.

    Re: Walker Turner Bandsaw

    Bob, I am very excited about the project! That is why I took it on, for a unique machine in my shop and to learn a little about old machines as I went along.
