heat curing epoxy....How many do it?

[johngalt312]

 

I like the heat curing machine. Makes the 3M DP460 and DP460NS epoxies cure even stronger. Zero need for it, though it works great.

golfmechanix.com has a seven station one for the same price.

Unless you are doing production work, try a copier paper box, lined with aluminum foil and a trouble light with a 100w bulb. The only thing I can't tell you is what time period is equivalent to room temperature for 24 hours. I've just used the 5min epoxy and haven't had a head come off, but then just work on my own clubs and I am a senior with a non-GolfWRX swing speed, not like the avg forum member who swings at 115mph+ (this is meant as humor).

I ended up doing the setup pictured. On low setting, felt like the clubs were retaining around 100-115 degrees. I let them bake for 2 1/2 hours, cool for 30 mins, no failures as of yet

[DLiver]

I use 24-hour epoxy and a homemade heat box (with 100w painters light). It usually gets up to around 100º. I run it like that for a couple hours in the evening, then let it cure on its own overnight. Everything is ready to go in the morning. It will make excess epoxy run, so you have to not go crazy with the epoxy.

I look forward to hearing from anyone who may have one of the Auditor Curing machines. I just received mine and really haven't had a chance to mess with it. I finally found some good instructions on it online and just started reading over them. If anyone is using one please send me a message and let me know what you think.......Thanks

One of the beautiful things of the 3M product is they dont run when heated - my observation

[LukeDonaldsTiger]

I recently did one club with Brampton 5/15 and put a heat gun on the floor in front of it. BBQ thermometer to check, adjusted distance to get 120F.

The Brampton is quick cure anyway, but I wanted to try it just for the heck of it.

I‘ll build a heat box with wood and aluminum foil lining and get a lamp. Heat gun is annoyingly loud in my apartment.

[LukeDonaldsTiger]

Follow-up: just reshafted another club, here’s my very DIY setup:

[cristphoto]

I've never heat cured assemblies since I only change shafts for myself - I'm not a business. I simply plan on when I next play golf and allow enough curing time. If re-shafting in the winter I will move the clubs upstairs after a few hours and sit in front of a heat duct. No rush, no stress, no failures.

[rexroh]

I have tried heating with a heat gun. I noticed that the epoxy became more fluid and appears as if it would get better adhesion. However I can see where too much or too prolonged heat could cause the glue to run off the glue areas and form in the base of the hosel or in the shaft.

[Socrates]

It is one of the reasons that OEM's use shaft bore plugs. No matter how viscous the epoxy is from the heat, it can't pool at the bottom. Most OEM's use a metered amount of epoxy so that the amount is exact and won't drain away or expand over the top of the hosel.

Bringing this one back up - does anyone have pictures or illustrations of their DIY curing cells or epoxy hot boxes? Would like to build one over the holiday here and looking for inspiration

[skraly]

I just use a small space heater.  Like this one.  I put it about 10" away from the club/clubs and let it run at full power for 2-3 hrs.  It will cure 24 hr. Golfworks epoxy so it's usable in 6 hrs.  It gets the heat up to about 110 deg at the hosel.

Use a heat lamp about 1 foot away.  Hosels get to about 100F.  Leave it on for a 3-4 hours.  

[ndoyle]

Yeah I was doing this last night - hosel temps were 85-95* depending on location. 

[JohnBauman]

I use a spare box and a cheap shop lamp from one of the big box stores. A 120W bulb gets me to 130-140 deg F if I recall. I haven't built much, but it has worked well for me. I also use 3M DP420NS because I need at least 15 minutes of working time to not feel rushed doing 3 clubs per.

 

 

[NPVWhiz]

I’ve done this a few different ways.  Once the epoxy sets for handling I’ve done it as simply as putting the head in the sink in a plastic bowl with 140 deg hot water.  A couple of reheats will get me to the range by the afternoon with dp810 and this approach.  In the spring and summer once they’ve set I’ll just let them marinate in the rear window of my Subaru for an hour, less if it is really hot.  That spot back there is a good hot box.  I’ve used a box and small space heater setup as well but the hot water in the sink method is my go to hobby at home setup.  I can check the temp with a cooking thermometer and be comfortable in a couple of hours.  I’ll always be thoughtful with medallions or cosmetic things where I might not want even that much heat but for most clubs it is fine.  I’m not putting a tm head with a carbon fiber component or that type of thing in there.

I just use a heat blanket set to high for two hours.  I can fit a whole set 4-P in it with them wrapped... I've temp gunned the hosels and they get up to about 160 after about 30-40 minutes of sitting in it.

I’ve also made one that’s similar it works great.

[03trdblack]

I use this Hot Logic portable oven food warmer that plugs into a wall socket. It heats up to around 165* F and you just put the clubs into it and zip it up around them. 

 

Cures 24hr epoxy in an hour or two.

It cures.   

[bvanlieu]

Heat gun on low pointed at hosels from 18"-24" away. I used a thermometer by the clubs to test out temperature at distance so 120-160 is easy to do based on distance. 1h at 140f, let it cool and its ready to go if needed but really this is about getting a stronger bond with heat curing more so then reducing the time (that's just a bonus)

I've laser thermometer'd adaptors/hosel sitting on the dashboard of my car in the summer and it can get the metal up to 150*, definitely effective!

My garage in Phoenix heat cures epoxy about 9 months a year.

Yup.  A sunny spot against any wall during the summer will cure most things in about an hour or so.

[subrew]

Just built up some Honma TW717M heads.  I just set the clubs on a small heating pad set to the middle setting, then fold it over the top of the club head and around the hosel.  Then an old sweatshirt sorta wrapped around it.  The inside tends to maintain about 100*-110* despite the garage being in the 40s overnight.  

 

I'm not in a rush for these, but I like to be consistent with my curing temps through the year.

Bingo, These work like a charm and it really doesn't take that long of a time.

I tend to use fast-set as a rule but it is pretty awesome to be able to build something new and almost immediately take it up to the range and see what we have.
