Thanks, Chad. I just called and left a message for Dean.

I got my bar from Dean, and after doing an exhaustive computer modeling study
of the angles the bar would have to reach, knuckle clearance while holding the bar, amount of mass at the rivet bucking point vs. loss of mass due to offset, I arrived at the optimal angle of 9 degrees 45 minutes, or 9 3/4 degrees!

(Actually, I just held it against the disc grinder and used the TLAR method!)

I think that 30 degrees moves the mass too far offset from where it's needed, JMHO.

It is apparently not listed there. I emailed them and got this reply:

Yes we have them in stock. They are $130.00. They are 4? long x 5/8? thick x 1? wide. These dimensions allow you to use this bar in almost any area. Let me know if you?d like me to send you one or if you live near enough to come by the shop to pick it up.

So, I guess you'd have to call them to order it. However, I had already ordered the one from buckingbar.net, which is same size, $120, and has "a slight angle on one end of the bar".

I'm sold. I just ordered one from Dean.

I have one and don't forsee using any of the bars that came in my tool kit, ever. Period. End of story!!

I did a build class with Troy (Grov-Air) and then had him assist with the first 35 hours or so on my HS etc. I bought a bar from him based on the class experience before even starting my kit.


Expensive yes, but worth it.



No angles on mine yet, bring on the grinder!!

I've drank the tungsten kool-aide too. Three rivets was all it took for all my skeptisim to transform into riveting nirvana.

You probably ground off an amount worth more than all my bars combined!

Dean at Webster Tools returned my call today about a bar. I already have a check on its way to him so he is sending me out a bar today. He said that the bars now have a 10 degree angle on them due to everyones feedback about adding an angle.

I'm still having difficulty with finding the right bar to help me set rivets properly so hopefully this bar will be what I need to get over the hump toward excellence.

I feel like I am in the middle on an infomercial.

Mine shipped today, too. Once it arrives, I expect to just point it at the rivet I want bucked and "Voila"!

A while back, I was bucking in the uppermost part of my rudder, Not a lot of room, really cramped for space. I had my smallest bar in there and beat up my skins (was not a happy camper). I got a sweet deal on Ebay for a .80"x.80" x 2" tungsten bar. I've been using it for weeks now and for bucking in tighter areas there is nothing like it. It weighs a little more that twice what my smallest steel bucking bar weighs. The tungsten bar is less than half the size of my smallest steel bar. For bucking rivets in wide open areas I still like the comfort and control of a larger bar. ymmv
