A Little Tip For Those Using The "tap The Can" Method With Dn

Recommended Posts

For those of you using the "tap the can" method for dispensing DN here's a tip that should help keep a tight seal and keep the screw from stripping out. As your well aware the walls of the metal can are really thin and the hole is easily stripped out if a little too much pressure is applied to the screw when closing. I had this problem recently and this is how I solved it.

 

I cut a square out of a piece of scrap Lexan that was approximately 1.5" X 1.5" and used sandpaper to rough up one side of it. I also used sandpaper to rough up a spot on the can that was slightly larger than the square of Lexan. Using a heat gun I warmed up the Lexan square until it became pliable and then bent it slightly so it conformed to the radius of the can. This was then epoxied onto the side of the can where you would normally thread your screw into. After the epoxy was fully cured I drilled a hole through both the Lexan and the side of the can that was slightly smaller than the screw that was to be used. The screw should be a little hard to start when it is first threaded into the hole and it will continue to be hard to screw in until the screw "cuts" the threads through the hole.  Once the screw has been threaded in the first time it will get easier to thread in and out. This was done a few days ago and everything seems to be working fine.

 

Another thing I did to help with dispensing the DN is to take the Dremel with an abrasive blade and cut a slot lengthwise into the screw. Only cut the slot about halfway up the screw. This is so you can back the screw out about halfway and the DN can run through the slot without having to take the screw all the way out.

 

hope this helps,

I got another idea, that will work too, take that piece of lexan and drill a hole thru it like a 1/4 inch or maybe 5/16 and then take a machine screw nut and epoxy it to the the outside of the lexan and insert the proper size bolt and then the hole will never wear out and u can still do the same method as before as cut a slot in the bolt and then u wouldn't have to pull it out as far.

For some reason, Ben doesn't want it to get out, but, he's of German descent. Thus, the innovation.

 

I've talked to him on the phone and, gotta admit...he sure don't sound German.  :)

 

Not sure why you would think I was of German descent. While part of my ancestry comes from eastern Europe it's not Germany. We do have some large parts of Texas that have many German communities though and man can those folks cook. Some of the best breads and sausages that will ever pass between your lips. Getting hungry just thinking about it.

 

As far as the way I speak it's pure East Texan.

"Thus.....the innovation."

 

 

 

innovation - the act or process of introducing new ideas, devices or methods

 

"German Engineering"

 

 

 

It was a freakin' compliment!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

:mad:

 

OK. I just misunderstood. Don't get your panties in a knot. :P

 

Thank you for the compliment. :)

Figured I'd chime in as well to help out.... I've been meaning to post this up - seems like a good time with the above trick as well...

 

Tapping the can:

 

This is the BEST method I’ve found for keeping DN fresh.   (BTW I have one small pint that’s still pretty good after 1.5 years…. Yes 1.5 years!!!)  It’s a getting a little thick now, but since I thin it to spray, it’s still working well.

 

Here’s what I do… Punch a hole on the bottom of the can smaller than the bolt you plan to plug it with. Once you have a hole, thread your bolt in to “plug it”.   I recommend finding a fine threaded bolt to use and possibly one with a wide flange.  Don’t get too crazy about DN dripping out – I found intentionally letting the DN slop around the bolt helps seal it.  It tried washers, neoprene seals, etc… just get the screw/bolt in the can the best you can and let the DN set up around it…it’s the best method..... although Ben's solution sounds like a much neater and cleaner way to work.  I also agree with shaving some of the bolt down  I just grind a big chunk away "midway" on the threads - this way when I back it out it can't "drop out" as there are stil threads above it and obviously threads below to seal.


 

Here’s my add…. I punch a second smaller hole on the top of the can and put a screw/bolt in that as well.  Now when I need to use DN, I remove the top, then bottom and the DN pours out nice and quick with NO AIR GOING / GURGLING BACK UP through the bottom hole.  When I’ve taken out what I’ll use, I screw in the bottom bolt, shoot some Bloxygen in the top and put the top screw in. 

 

I believe this method has a few advantages…

 

 One – the DN pours out so much faster with a hole in the top… so if you need a ½ ounce you don’t have to wait till next week for it to seep out of a little hole on the bottom.

 

Two- by not allowing air to gurgle up through the product as it drains out the bottom – you avoid air/DN contact and thus keep the product “fresher”.

 

Three- by spraying Bloxygen down the top hole you push the lighter air up, and only have the inert gas over the DN… again for more freshness!!!

 

I also try my best to avoid tipping the can over.  I store it upright and when using it try to keep it upright even when removing the screw to avoid mixing the “air” in the can with the product.

 

 

I hope this help... I’ve sure some of the real vets can help out here, but as a hobbist that makes 20 or so hardbaits a year – this is what I’ve learned on top of what others have shared.

Interesting. I planned on putting a few layers of aluminum tape on the area to tap.

 

Before putting my faith in aluminum tape I would put a little DN on the adhesive side of the tape I was planning on using to see if it had any adverse effect. The solvents in DN could eat away at the adhesive and leave you with quite a mess.
