Homemade Reduced Weight Bar

[mdavlee]

It's thin but hardened steel at least near the rails. I'd be nervous trying to punch a hole through it. I've punched 3/4" holes in A36 plate with some of them.

If anyone tries to "punch" a guide bar, please have a video camera rolling. It could make for great entertainment for the rest of us....

Don't forget yer checkbook, or credit card with a sizeable amount available to spend when on the hunt for a good mag drill...'bout like hunting a core drill...expensive stuff.

I don't know of the quality of the Relton Annular Cutters, but Hougen is superior to the brands I am familiar with.

Pig fat works well as lube.

There used to be an Industrail tooling company that sold it in a roll similar to the old cardboard drill sleeves.

Where can I find a pig or a farm for that matter.
No farms nearby ,,, unless I go to the TN gtg!!!
Yeah man!

Group buy on the drill?

That's what we have at work. They are awesome.

Fein makes exceptional tools...we have many hand-held pneum shears, skin saws, cutters, etc in the aircraft maintenance world.

Question on the Panel Bond; Is it sandable?

Ish...

Like sanding most plastics, likes to "fuzz" a bit.

Okay. So similar to sanding the cured two part epoxy. Too much friction, and the surface gets soft?

I took the advice of @USMC615 , and picked up a 3" grinder yesterday. It's one of the cheap Harbor Freight models, but the wheel is vertical, so it seems more conducive to doing long cuts, and keeping square.

I already tried it out a little….I bought one of the 20" CN40 404 063 bars from LCS for $22. I lengthened the slot so I can use it with an adapter on my 288 or 395 with a 404-8pin. I figure it will be a hoot to run next to someone blocking firewood with MS291 or 455 Rancher……LOL!

Yes real similar.

You don't want to buy one, you want to know somebody that already has one!

I think when making a RW bar one needs to think what kind of cutting he intends to use it for when done and how much flex is acceptable for intended use. You can remove a lot of stock for a short limbing/cookie cutter without a problem. A longer felling bar, strength and minimal flex is far more important. IME its only when the bar is used horizontal that flex is noticed.

Great post.

I like the lightweight of my Oregon RW bar, and in bucking cuts, and limbing it handles very well, but as you mentioned, once a high flexing bar is turned horizontally, the flex seems to increase, or at least that is my perception.
This is why, after @junkman asked about measuring flex of the bar I was modifying, I realized that weight savings isn't everything.
I believe my first attempt turned out better than I had hoped it would. It's crude to a certain degree, but it has promise, and should be very functional.

I'm within 1 1/2 ounces of my Oregon RW, but with almost 33% less flex.

Mag drill don't work on guide bars.....at least not with the standard Hss bits. I've tried
