Making a 3/4" dog fit a 20 mm hole snugly

[Claimdude]

Anyone here run across a bushing that is 3/4" ID and 20mm OD? I would like to get the centipede no slip dogs but they are 3/4" only so would be sloppy sitting in my MFT top holes.

Thanks
Jack

I had thought about trying an automotive speedi sleeve for exactly this but haven't done it.  The bushing would need a wall thickness of only 0.010" and I can't think of a bushing that would be so thin walled.  There is a 99076 speedi sleeve on page 8 of this catalog  by SKF that has a wall thickness of 0.011" to fit a nominal 0.75" shaft that may possibly work, but it may just be a tad too thick.

Heat shrink wrap for electric cables? Centipede no slip dogs are plastic anyway.

If the posts are plastic you could punch dimples with a pointed punch or very small nail set to make the old a little bigger for a friction fit. If you overdo it just back up with sandpaper.

Thanks guys. I am going to look into the 99076 sleeves. The others are options as well. Thanks again.

Thanks for that info [member=59951]Dick Mahany[/member] , That's exactly what I need for a motorcycle trailer that I just rebuilt and the wheel seal surfaces  became damaged from 40 years of outdoor storage.

[member=44099]Cheese[/member] you are welcome.  I have used many of those over the years rebuilding Landcruiser transfer cases and axles.  They do the job perfectly and all of those annoying leaks will be gone.  Best of all they're a breeze to install.  Good luck.

George,

This is exactly what I was looking for! I ordered 20 of them today. Warning the shipping is a flat rate of $20 but the parts are only 30 cents a piece. Not bad for a 3D printed part!

Thanks

Why not just buy the proper bench dogs the guy sells? He has some interesting stuff he prints for an MFT table. Thanks for sharing.

Peter,

I was looking for a way to use the Centipede No Slip dogs that are 3/4" in my 20mm custom MFT top.

Clearly I am clueless with what you are trying to do. Thanks for clearing it up.

Here is another option though, albeit slightly more expensive. They have excellent grip though.http://festoolownersgroup.com/festool-tools-accessories/i-did-it-all-for-the-cookies!/msg552724/#msg552724
