Topic tags/keywords: mortiser

I’ve got a Delta bench mounted mortising machine (14-651) that’s about three years old (out of warranty) and the roll pin that holds the handle to the machine just failed. It’s slightly under 1/4” (about 0.237”).

To those who are good with machinery, what would you recommend to replace it? Is it designed to be soft so that it fails and prevents damage to more expensive parts of the machine? Or should I use something harder to prevent this from happening again?

I could just order a replacement from Delta, but they are showing out of stock. Will any old roll pin work, if I can find one from another source, do I need any other specs besides the length and diameter?

Any assistance would be appreciated.

Replace with the same thing. It’s better to have them break than to replace it with titanium and have something costing 20x the pin break.

They’re stock sizes. Your hardware store should sell them back with the nuts and bolts or you can get one here:

If you have a Tractor Supply nearby they will have it. Like Joe said, probably not good to substitute
