Delrin Sleeve for the mortise
Delrin Sleeve for the mortise
I had a pipe with a wiggly stem and dicovered an oblong mortise. What I did to fix this is inserted a delrin sleeve and re-turned the tenon to fit the sleeve. Delrin and vulcanite make a very nice fit, just as nice as delrin on briar.
With an OD of 3/8" and an ID of 5/16" there was no room for flats or grooves to help hold the sleeve. I used medium thickness CA glue rather than epoxy because I believe the CA has a higher chance of not breaking down with the heat. (this is something I've had a chance to experiment with as I screw up fittings.) Epoxies seem to break down gradually after just a bit of heat has been applied where-as CA glue needs alot of heat and will just let loose at once.
Anyone else have thoughts on any of this and is the sleeve a good idea to begin with?

Cyanoacrylate adhesives. Fancy super glue. See the below article.

A quick comment on CA glue (aka super glue): it is usually fragile. Dropping the pipe can easily break the bond. The heat a mortise should experience is negligible. As such the flex of an epoxy bond generally makes it a superior choice for most pipe applications.

I'd agree 100% I've been making Delrin sleeves for years with my pipes and I've found the best results by far are with epoxy.Tyler wrote:A quick comment on CA glue (aka super glue): it is usually fragile.

Depending on the wood I need to glue I either use G2 Epoxy or 5 Cure Epoxy. Both are made by a company called Industrial Applications. You can get either or at Lee Valley Tools.

Yes, the T-88 is powerful good stuff. The only drawback is that it takes a minimum of 24 hours to cure enough to work, and sometimes as long as 48 hours. However, if you have a pile of pipes in process, you can stage things so that you're not eing held up by one operation or one pipe.bluesmk wrote:I totally agree with Tyler and Steve. I use epoxy exclusively, the brand:System Three-T88. It's a structural epoxy, heat and cold resistant,and flexible to boot! By the way, Kurt uses it as well.
