Question about Saws

1 Answer

I have a Craftsman 7 1/4 circular saw Model 315.10851 that I bought around 1980. It has been a reliable tool for numerous home projects over the years. I recently put a masonry blade in it to cut landscaping stones. It worked fine at first, then the blade started slipping. When I tried to tighten the bolt the blade the motor turns even when I hold the blade. I realize the problem is a result on not using the "blade washer" that has a flat spot which matches up with a flat spot on most blades. The masonry blade had only a circular opening so I didn't use it. The problem now is how do I get the masonry blade off of the saw?

    No, there is no mechanism to stop the motor from rotating.

  • davemamer Jul 06, 2010

    Thanks for your thoughts, the problem is that the blade is too loose to use. It stops as soon as soon as it hits any resistance. Maybe it's time to buy a new saw.

  • davemamer Jul 06, 2010

    I took the end cap off earlier, but it didn't seem like there was much to get a hold of. I'll go give it another try. As you said, I can't use in now anyway. I'll sign on tomorrow and let you know if it worked.

    Thanks for all the tips, I finally found time to work on the saw again. Like you suggested I took off the end cap and fiddled to find a way to hold the armature without damaging it. I finally found a way to wedge my finger. It hurt for a bit, but I got the blade off and I didn't damage the saw.

    Thanks again.

    I am sorry to hear this ... yours is definitely an uphill struggle. Maybe you should just keep this saw for concrete work. That is what I did in the same situation. So, now I have a couple of saws ... one definitely for concrete work.



    Thanks for your interest in FixYa.com and thanks for evaluating my response. I am sorry it was not of more help to you.

  • A Miller Jul 06, 2010

    You could remove the motor end cap and grab a-hold of the armature and maybe get the blade on or off that way ...



    Yes, you might damage the motor ... guess what, you cant use it now ...



    Might be time for a new one, you are right.

  • A Miller Jul 06, 2010

    Thanks ... at least get your blade back ...

  • A Miller Jul 12, 2010

    Glad you saved the finger ...



    Your post is dated tomorrow ... I guess you are on the other side of the date line from me on the East Coast of USA.

I need a switch for my black & decker 7 1/4 worm drive saw model 7395 type 1


That tool was discontinued in 1980 and parts are obsolete. You may be able to use a Skil 77 worm drive switch as many of the circular saw switches were configured the same. The switches are usually marked with a 1 and 2 on the back so make sure the wires are put on correctly as some will have the 1 on one side (top and bottom terminals) while others are on the top or bottom (next to each other).

Sears sells millions on these saws and you probably saw less than 1% if people who had problem w/their saws. They make a good saw and you can feel assured it's a good unit.

My Craftsman 7&1/4 inch 12 amp Circular Saw(Model 315.108330) slips while cutting. The motor keeps spinning but the saw stops rotating. Can I Fix it?


Most circular 7-1/4 saws have a bolt and a compression washer that acts as a brake shoe that holds the blade secure but under dire circumstances will allow the blade to slip some rather than hold the motor shaft and allow burn out. The compression washer under your bolt has become worn and doesn't grip the blade securely. You can find a split washer that will fit under the blade and give you some more friction, or go to sears and order another compression washer for your saw.In the Sears Parts List found at: http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Saw-Parts/Model-32018780/0247/0744410/50035950/00001?blt=06&prst=&shdMod=

Need substitute switch part for sears saw


Sorry , but go buy a new saw. Your not going to find an aftermarket
dealer that carries this switch.

Trying to rig some other switch is not worth the trouble over buying a new one. If the switch is not available, then the saw is old.

Cannot remove blade from craftsman circular saw


without knowing the model number I can only assume that it is a circular saw and the blade is on the right hand side and then the bolt should be a standard thread. Hold the spindle lock in and turn the bolt counter clockwise to loosen. If other than it would probably be a left hand thread and do just the opposite. Let me know and if so please provide the model number so I can look at a breakdown for the tool.

In the past I have clamped a pair of vice grips on the old blade so I could remove the bolt from the arbor.

Boken shaft of old Craftsman skill saw


I have repaired many craftsman circular saws over the years and find that they share some parts with other brands. When sears drops a model number you must try to discover who made it for them. You did not list a model number, however when I need to identify a saw w/o the number I look at old part breakdowns and look on ebay for similar looking saws. Try and identify which manufacture made it for sears. Many were made by skill over the years so I start there. Once I find a good match, I check for available new parts. If not available, I check pawn shops and small tool repair shops for used parts, even burned out armature then have it rewound at www.eurton.com If you value your old saw take the extra time to look around, if not buy a good used saw at a pawn shop. I prefer Makita or Milwaukee good used about 40-70$; good used craftsman 20-30$, take a good look at the armature commutator and check that the arbor bearing is tight. Good Luck and email if you have questions.
