Homemade Reduced Weight Bar

[Jon1212]

I mentioned 'micro-balloons' in an earlier post. Adding these to the epoxy resin thickens it, and converts it into a paste or filler. Used a lot in boat building.

West System is one of the better known brands, and offers a lot of technical info. You could contact them, describe your application, and ask their advice.

Here is a flex image with oregon lw bar that would not load last night ,shows the flex better ,if the bar flexes too much on a long bar ,it is like cutting with a wet noodle almost .Yes the shop is a mess

Next time.

Once these thunderstorms let up, I'm going to hang the weight on my Oregon RW to see how much flex it has.

Oh, you've got one of those?

Dats what I Habe.

Si. That's why I chose to cut up a 32" Power Match.

Bar Flex comparison update(hanging 10lb weight from midpoint. All bars are 32" 3/8 050 D009.

32" Power Match with cutouts- 7.76mm

32" GB Roll Top no cutouts- 3.43mm

32" Power Match RW- 9.23mm

32" Power Match with cutouts filled with two part, and cured for 15 hours- 6.30mm

So leaving the little bits in the middle helped rigidity a lot .

Apparently.

I'll be curious to see if the flex tightens up on this one, after the epoxy has 24-48 hours of cure time.

I'm going to swing by FedEx, and weigh the modified bar to see what the accurate "actual" weight is.

I like the results. Curious to see the weight comparison between the factory RW bar and the homemade one.

So I took my used Oregon 320RWDD009, and my Homeade version by FedEx today.

Oregon RW= 3.25lbs

Jon1212 RW= 3.75 lbs.

I've got enough room towards the tail for another cutout, so I'll go ahead, and get that done, which ought to put it closer to 3.50 lbs.

 

[Jon1212]

Also, after full cure time on the epoxy, the flex measurement is 6.20mm So it did tighten up a little more.

Once I get done with the fourth cutout, and get the excess epoxy cleaned off.

Hahaha! +GFY.

I need to figure out a way to smooth out the filled areas. The discoloration is from trying to high speed sand it. I'm thinking a random orbit might be better.
