turned a seam ripper kit this evening and the rubber O rings will not fit into the brass tube…tried enlarging the inner diameter of the brass tube but have had no luck in getting a good fit and a few of the rubber O rings are now worn…anybody tried this kit and have you run into this same problem?...will probably take the kit back to Woodcraft for a refund…

You might try warming the brass with heat gun, hair dryer or whatever you have there and put the o ring in the freezer for five minutes then try again.

How close of fit are we talking here

O rings of many varying sizes are readily available

“The O-rings when installed on the blade holder make it to large to fit inside the brass tube. I have found that by turning the blade holder on my lathe in a chuck fitted with pin jaws I can sand the grove and reduce the diameter enough that the O-rings will fit inside the brass tubes. It take a few attempts to get the fit right. I also chamfer the brass tube slightly. I’ve also noticed while test fitting the blade holder (with the O-rings installed) that twisting the blade holder while pushing it in the tube works the best. Often no further modification is required. – See more at:

Others have had problems as well. Check the reviews and maybe something will work for you.

At one time Woodcraft was a reseller for Berea Hardwoods products. Not sure if that is still true. Berea instruction easier to follow. Berea definitely tells you to increase tube size with sand paper, oil & wipe off o-rings before installing. Just assume use a dowel & sandpaper to enlarge the tube.

I have been meaning to update—-I went ahead and tried a new seam ripper kit…I used sand paper followed by fine steel wool like some suggested but had no luck…I then used a pair of small scissors to flair out one end of the brass tube a bit followed by fine steel wool and it worked very well…This will be a X-mass present and hopefully they will like so I can make more but I think I will try a drop of oil next time :)...thx everybody…
