WOULDNT IT WORK BETTER AND LAST LONGER IF YOU ADDED A WASHER TO THE BUMP SIDE GIVING MORE STRENGTH TO THE CAP BY ABSORBING MORE OF THE FORCE AND DISTIBUTING THE BALANCE OF REMAINING KINETIC ENERGY TO A WIDER AREA OF THE CAP?
Thank you for the video. Very good idea. The main reason I watched the video though, was to see which way that darn spring went in. I've had this for maybe....12 years, but got a new trimmer head and at the same time it ran out of fuel, for some reason the string broke on both ends and there was no way to get it out unless the head was taken apart. I didn't realize I had it in wrong and it flew apart ...sooooo....off to RU-vid I went. Thank you again! By doing this, I won't even have to get a new one for awhile.
I used to put a short lag screw(bolt) in the Sthil bumpers !! It would extend the life for awhile but I don't know about "Bulletproof" 🤣 . I just went to the speed feed heads myself and love not having any drag on the head. Makes a perfect level cut on Thick Augustine yards when you have large areas to trim. Good tip 👍
My speed feed with .095 line gets in the ground way to much. When you try trimming the Bermuda it pulls the line all the way to the ground causing a brown spot. Almost every time you try to trim with it. Good RU-vid channel!
Great idea! Can you also hand turn the speed feed to make more line come out? I'm sure i saw somebody do it, much faster to tap but they wear down unless we use your bulletproof method 😊
Thanks for the Upgrade Tips! Just bought a new Speed Feed 450, and did the upgrade before I installed it... Glad it ended up fitting my trimmer lol **UPDATE: My bolt went missing! First time out I had been cutting for probably an hour or so when the cheap line the head comes with ran out, so I went to refill the head with line, and the bolt was gone. not really sure how it loosed up, as I had it tightened down as much as possible. After I got back to the barn later, I took the head apart and the nut was still inside. I replaced the bolt and used a nylon lock nut this time instead of a regular nut. i also added some thread lock too. A left handed bolt/nut might also work but I don't have any and wasn't going to bother buying one. I don't expect I'll ever have to replace it again with a locknut and threadlock, But if it ever did it again somehow, I'd replace it with a left hand threaded bolt/nut.
@@Customsouthernarms I think that's the only difference between the two. I can fill this 450 with about 21ft of .095 Maxpower Twisted line. Lasts a good while with the Max line, even with all the heavy weeds and light brush I cut on our property. And cutting around fences too. Usually takes me between 3 to 5 hours to cut everything, so more line is gooder :-)
I think I have lost my mind. I did this to a trimmer head three years ago. I found a deal on some after market speed feed heads (5 for $35) . I now have 5 speed feed trimmer heads with a bolt, 2 flat washers, a lock washer and nut. I can't burn through enough string with this idea. I used a lock washer under the nut so the nut won't walk itself loose. Great idea thanks for the instructional video
Probably best to use a nut with a nylon locking insert (Nylock is one brand) to make sure that the nut does not loosen. That's what appears to have been used in this video.
Wonder how its gonna wear down, I like the idea and ended buying just the caps from Amazon. I wondering if you'll be able to take off nut to replace it. I'll def try this out cause I wanna see how long itll last. Thanks man
Nice idea, however.. The steel bolt head when tapped on certain rocks or weathered concrete will likely cause a spark; the flint and steel concept. My concern, mostly regarding the drought-prone western states is a random spark in dry grass causing a wildland fire. Saving money on trimmer head replacements is a consideration but don't forget the possibility of paying for fire suppression costs if you are at fault. I might suggest an alternative to the steel bolt. My brother-in-law had a propane business. I went along to help on a few delivery runs. I noticed he had a brass hammer mounted on the working end of his delivery truck. His reply to my question about this unusual tool was, "A brass hammer is less apt to cause a spark than a steel hammer." Makes sense to prevent sparks around propane gas. I try to always consider safety to self and others. Fire season in the western US is a worrisome time where dry vegetation is extremely flammable. Any sort of mechanized mowing or trimming of non irrigated vegetation is seriously discouraged. I can't say for sure that a brass bolt would be better, they are more expensive. As they say, food for thought.
That would be an interesting test, though I doubt it would ignite that would be interesting to get some fire starter husk and see how many times you gotta grind that bolt directly on the husk to start it 🧐 I imagine it's not like a angle grinder sending sparks but you never know there could be a micro spark somewhere between the bolt
