I while back I was given a trim saw for free. I’ve now spent somewhere between $100 and $200 getting it running. I thought I had everything ready to go and I just ran into a problem installing the blade. I’m using a ten inch blade from my other trim saw. My other saw has a 5/8 inch arbor. My new saw has a 1/2 inch arbor. I found a brass bushing that came with the blade and attempted to reinstall it in the hole. It fits, but won’t stay in place because the washers on either side of the blade are recessed, so there is nothing to hold the bushing in place. If I were to purchase a new blade, would that bushing stay put? Is there a way to make my old blade work? Should I order a blade with a 1/2 inch hole with no bushing? The blade:  The washers (is there a better name for these?):   |

I thought of that, but I didn't know if it would be strong enough. Have you done this? |

I have had bushings that would not stay in place before but the blade worked fine. Once the washers are snug against the blade the bushing doesn't matter so much...............MrP

Why dont you stick a washer into the recessed areas that are just as thick so they are flush with the plates. You can always drill the center of the washers to fit your arbor.

Finding a washer the exact thickness was the reason. The recesses are also different depths on both sides. I’ve super glued it for now. I’ll find out tomorrow if that works. |

Don't file the recesses away in the blade washers, they are pretty important. A couple small rubber grommets or just some cut from yogurt lids would do the job. The glue may work fine by itself, you can get generous with the super glue, if you ever want the grommet back when the blade wears out just get the blade hot and the glue will fail at about 225 degrees.

Super glue is not a perment fix.
Purple locative works on press fit but I don't know the gap.
Red or green works on threads but is perment.
Buy stainless so it doesn't rust.
McMaster Carr (a mail order)has many different size washers.
Order from the Internet.

Those recesses are there for a reason – to clamp the blade farther out from the arbor hole and to stiffen the blade. You don’t want the exact thickness. Just enough to prevent the brass reducer from falling out if the glue fails. Different depths no biggie – any combination of ½” washers or plastic lids will do to keep the reducer in place. And hopefully, like MrP said, it won’t really matter . . . just a little insurance to keep the blade centered properly. |

That damn painter in my head, just use oil enamel. or her finger nail paint.
As for the radius cut outs on colliers / flanges.
That space, to put more pressure out on the radius. of the blade. prevents dishing.
On cross feed, I've lathe off the edge of colliers. hanging rock below vise deck.
Lathe cut flanges only. slab saws shop tool all.
grinding wheels maybe pressed (thick.)

I have one I super glued into a 10 inch and I have done it to 6 inch blades as well with no issues. Its been my experience that pressure on the thin blades can cause distortion which I think is the reason for the cut outs

Ok, the blade is on, but I haven’t used it other than to turn it on. I will cut with it sometime tonight. I superglued it, then filled in the center of the gap with plastic washers from an Olivio butter container. I left some space so that the metal should still tighten up farther out on the blade, but hopefully it will help hold the bushing in place if the glue lets go.
Thanks for your help, everyone.

I just cut fifteen crosses for tumbling on my new saw. Everything is working great.

If it doesn't stay, lay blade flat and using either a center punch or big nail punch about 4 places around the outer edge of bushing where it meets the blade hole.

I guess i should of made it a little more clear that I was talking of hand filing this washer down on the flat side, not the recessed one and the tightening plate.  Its cutting is the main thing now. lol |
