Re: Replacement spring for Harbor Freight saw
开云体育Well, I figured Grizz was the best chance, but there are others. There is also Jet, part number HVBS462-047 for their spring. Lot of Jet dealers out there. I’d contact Jet directly. And Northern Tool, Item 122 on their 49464 band saw. They don’t have part numbers, similar to Horror Freight. ? Busy Bee Tools, (Canada) Rikon model 15400 band saw, the spring is P15-400-127 Even Home Depot sells 4 x 6’s, but they are not much on service parts. ? Bill ? From: 4x6bandsaw@...

Hi Dave?
Do you need another spring because an eye broke off the end? You can thread a bit of aluminium (or any other metal) to screw into the inside of the broken end of the spring.? It has a diameter and pitch you can measure.? Use a round-nose lathe bit same diameter as the spring, not a vee-bit.? If you choose a pitch the same or a wee bit bigger it will thread in nicely.? Loctite to hold it in place if it? turns out a bit loose, otherwise it will probably be impossible to remove.? Tap the end M6 and thread&Loctite? in the tensioning adjustment rod.? Cut off the hook on the tensioning adjustment rod (or use a bit of allthread) and your done - jv? |

Re: OT: Bainbridge 712 resurrection
Robert,
Didn't know that, thanks for the info. The funny part about this saw is that both of those situations may have bee. True! :)

Re: OT: Bainbridge 712 resurrection
开云体育As I’ve written before (but maybe not here?), all Single Phase Capacitor Start AC motors are reversible.? Those that appear not to be just don’t have the necessary wires run out and require partial disassembly to reverse.? ? Generally, if a manufacturer is making a bunch of units that DON’T require reversing the motor and are buying the motors from a manufacturer instead of a distributor, they’ll buy a motor that turns in the correct direction and can’t easily be changed because it is a little bit cheaper.? If a wholesaler or retailer is buying motors to stock for resale as motors, they’ll buy ones that can be reversed by just interchanging or swapping wires.? This costs a few cents more but cuts their required stockage in half.? So if you find something like a band saw with a “reversible” motor, it was probably either a low volume production or a replacement motor. ? Robert Downs ? From: 4x6bandsaw@...

Re: Saw stand wheels, on floor or off the floor?
Lots of good information in this thread.

On motors and wiring, I continue to be surprised that nobody seems to be advising the use of motor overload protection ("motor starters") with these saws.? Given the ease with which a saw of this sort can jam, and the temptation to go off and do something else while the saw is working, overload protection seems (to me) an obvious need.? Either the NEMA type, using selected "heaters" or the IEC bimetallic type will work.? NEMA motor starters have gotten very expensive new but are easily scrounged, at least around here (US).? Typically heaters are selected from tables based on the motor current or horsepower, but you don't have to use the full capacity of the motor.? There is no reason not to use a lower rated heater or setting to cause an "early" trip to protect the blade or whatever. Safety note:? Many motors have internal automatic resetting thermal protection (fan motors, etc).? It's unsafe to use this sort of motor, as is, on tools as it may restart without any warning if you forget to turn the control switch off after an overload trip.? No reason not to use the motor, but the thermal protector should be bypassed or replaced with a manual reset type (the sort with the red button).? Or of course, IMO, use an external motor starter. am At 09:30 AM 10/9/2018 +0000, you wrote: ? |

Re: OT: Bainbridge 712 resurrection

It seems yours moves opposite to mine Bill.?
More twist on the blade makes my blade move toward the rim on a 4x6's wheel (more strongly at the bottom than at the top).?? Retracting your bottom guide will twist the blade more (twists through the same angle over a shorter distance) and your blade moves away from the rim.?? Whatever, twisting the blade definitely affects where the blade rides on the wheel and as long as there's clearance (or at least no pressure) between the blade and the rear support roller, the act of cutting pushes the blade back without any tendency to derail - jv? ?? |

Re: OT: Bainbridge 712 resurrection
开云体育That’s a good point! I have a fixture I built for cutting angles. In order to use it for larger diameter tubing, I have to slide the lower blade guide toward the drive wheel, as far and close as it can go. When I do, just running, the blade will track about a 1/8” to ?” off the shoulder, and the vertical bearing in the lower guide. Soon as I start a cut, the blade moves up against both the shoulder and bearing. Doesn’t seem to hurt anything, or effect the cut. ? Bill ? From: 4x6bandsaw@... [mailto:4x6bandsaw@...]

Re: OT: Bainbridge 712 resurrection
Hi Darren,
Nice looking saw! You’ve done a great job on it. As to the wheels, I stuck mine on 4 swivel wheels about a year ago, the 2 on the end away from the motor are locking. When I forget to lock them & use the saw vertical it runs away from me! You may want to sort something out so yours says put when you use it. Having the saw on 4 wheels has made it so much nicer to move around compared to the 2 only on the motor end. Cheers & a Happy New Year Kerrin |

Re: OT: Bainbridge 712 resurrection
开云体育Do a bit of tweaking, and see whatcha got. Can’t get enough….may have to do a bit of a mod (grinder) so you can get there. FYI, my saw, doing nothing, the blade will generally ride on the idler, but be 1/16” to 1/8” of the shoulder of the drive wheel. The edge of the blade also misses the vertical guide bearing at the drive wheel end by the same gap. Soon as I hit a piece I’m cutting, even slightly, it’s where it should be. Been that way since I got it. No problem with performance. I don’t worry about it. When blades start poinking off….then I do something. ? I saw some pics some years ago, where a guy made a mount for a motorcycle seat, to cut with his saw in the vertical position. He had the same problem you are talking about. Hard to stay steady & cut, when your standing over a saw in an awkward position. Clever, and different, solution. You have an old Lay-Z-Boy chair around? The “Lay-Z-Saw”. (I like it!) ;) Bill ?
