Yep...

Re: tooth bar and cutting edge

Thanks for the info, John, and thanks for the promotion. Don't feel bad, many people make the same mistake, but a Master Chief of my rate would be FTCM instead of FTMC. The "FTM" stands for Fire Control Missiles (like an AQ in aviation ratings). I was in only 13 years and made Chief (E-7) but had problems with bloodclots in my legs (thrombo phlebitis like Nixon had). They gave me a choice of finishing my time on shore duty and frozen at E-7 or a disabilty retirement. I took the retirement and like you "never looked back." It was a great time in my life, but it was obvious because of my health issue that I needed to find something else to do. Here is a photo of the USS England firing a Terrier missile. That was the weapon system I worked on. Missile guidance radar was my speciality.

My technical background has always served me well and the instructor training I had in the US Navy has propelled me into a very exciting and rewarding career. Have you ever used your electronic skills gained as an AT?

Hey the mighty MK10....JimI when did you get out...When I got out in 94 The FTM was simply FC if I understand you.(Fire Controlman)..I was on the USS Dahlgren DDG43 and USS Richmond K.Turner CG21(OLD Destroyer reclassified DDL I think it was )

GMM3 up for E5 when I walked away...figured was time to stay home with the wife...

Re: tooth bar and cutting edge

Paul, I guess we've sucessfully turned Boomer's thread about tooth bars into a sea story, but maybe he will forgive our indiscretion and not "roast" us. There used to be three ratings in the surface navy for "FT": FTG - guns, FTM - surface missles, FTB - submarine ballistic missles. After I retired, they changed the rating to "FC" which was a retro-move because that had been the designation originally when the rating was established. Like your rating, which was divided into GMM, GMG, and GMT, it all became just too confusing. Did they leave those designations alone?

I started working on the SPG-55A/B Fire Control Radar and became a Weapons Systems Chief before I got out. I've run many DSOTs (Daily Systems Operability Test) at midnight underway with the TSAMs (Test Surface to Air Missile also called "pretty birds") on the MK10 rail and a GMM on the sound-powered phones, trying to keep awake and check indications while salt spray breaks over the bow. Did they still do it that way when you were in? I was on the Leahy DLG-16, Yarnell DLG-17, and Gridley DLG-21. They were all reclassified as Cruisers and had their designations changed to "CG" instead of "DLG" which was a political move. I retired in 1981, so that tells you what an antique I am.

My appologies to everyone for the TMI (too much info) nature of this message. Between "old salts," the current runs deep.

Re: tooth bar and cutting edge

I have my ideal operation of a tooth bar shown in the attached diagram. In the next post, I talk more specifically to its features.

Re: tooth bar and cutting edge

Here is the image from the last message shown so I can discuss it.

My bucket has the bolt-on cutter bar shown in blue. I'd like to put on a toothbar that would seat against the cutter bar as shown in diagram "A" (I drew it on the outside, but actually the toothbars bolt to the inside of the bucket.). When I would backdrag, as shown in diagram "B", the toothbar would rotate up and away from the cutting edge. Have you ever seen one that works like that, John? I may be wishing for too much here, but you gotta start somewhere./w3tcompact/icons/smile.gif

Jim
On dozers and the such they have "root rakes" which bolt on the top of the blade and like your design work going forward then in reverse you can back drag.. I believe you got something there that would work.

Re: tooth bar and cutting edge

JimI,

I like your idea of a the modified toothbar (which john4nh called a "root rake"). Actually I would like to a design that would pivot the way you described and would be able to lock. I found the teeth on the toothbar to be great when backdragging with the bucket for a rough distribution. If you move fast enough backwards with the teeth pointed partially down, they (the teeth) combined with the cutting edge sitting a couple inches higher quickly distributes the material very evenly. I learned this trick from a guy who had a concrete business and used a skidsteer for distributing gravel.

In the absence of the design you proposed I end up backdraging with the teeth rotated up and use the back of the bucket for final smoothing (I think the NH manual recommends using the back of the bucket for backdragging).

Just my 2 cents...

Re: tooth bar and cutting edge

Your idea, in theory and on paper it looks great, but in real life it may not be practical…

With the toothbar, having multiple steel shanks shaped and form fitted over the bucket’s cutting edge, this makes it a cohesive unit as a whole assembly… it’s much stronger.

Lacking the correct engineering terms to express myself properly, it’s like the difference of someone hitting you with an open hand or someone punching you with their fist… it’s the same hand used in both examples, and the same mass doing the striking, but the clenched fist is stronger and will do the most damage.

Besides, it’s only two bolts holding the toothbar on, you need to remove…

Hey, that’s why God invented boxblades and rear mounted blades… just for that “smoothing”purpose… /w3tcompact/icons/wink.gif

If you had different shaped shanks {without the bottom lip as in your picture}, yes it will work, but I don't believe it's certainly not as strong as the original intended purpose.{aggressive ground digging}

It's one of those things... you'd just have to prove out for yourself and see if you're happy with the results...

Re: tooth bar and cutting edge

John and DaveV, I defer to your expetise on this one. You both make such valid points that it's hard to think of any argument. I'd say that just because I can draw it, it doesn't mean it will work "where the bucket hits the dirt." The idea of a rigid single unit makes good sense, and using the back of the bucket to backdrag is also a very easy "fix" for not making ruts. As a matter of fact, having the blades rigid might make it possible to scarify on backdragging and then dig going forward. Thanks for your thoughts and advise.

...and John...Isn't a boxblade just counterweight so you can do everything with the FEL? /w3tcompact/icons/smile.gif/w3tcompact/icons/wink.gif
