Favorite tool for removing core,and why

[outasite]

For those that have,or are doing core work.Whats your favorite tool and why? What works the best on reasonably good core.The rotten would be fairly easy by most methods, but the good stuff,not so much.

[nitro_rat]

I like to use a sawzall to get under the loose skin. Unless the core is really good you can usually get up to the edge with the saw then peel the skin off. A circular saw with the depth set carefully is next to dice the core into sections or strips. Follow up with an “oscillating tool” to pop up the sections. Make the sections as small as you needto to make them easy to get up. Pry bars, chisels, scrapers and hammers are also helpful!

My tool of choice is the lancelot. But it ain't for the timid. https://www.amazon.com/King-Arthurs-Tools-45822-Lancelot/dp/B0000224SJ

+1 on the Lancelot. It made short work of transom removal as well. But the minute that you aren’t scared of it, put it down. You are about to get hurt.

I also used this:

It never showed any signs of wearing out either.

I’ve been wondering about that harbor freight wheel. I guess I’ll pick one up next time I’m in town...

[XstreamVking]

Harbor freight? That is chinese junk and def could hurt ya. I don't buy anything from them. Purveyors of junk products.

Air chisel but know how to use it and a 4" grinder.

[W2F a V-King]

best tool ever for this imo...

423858 423859 The picture of the blade is not the exact one I used, but it is a decent picture of what came with my kit from Dewalt, and I bought more of these as you will go through a few. It lays almost flat against the hull and cuts flat through the tough good core areas.
And then to grind away larger areas of uneven glass, core or what ever...This grinding wheel below (what NicePair suggested) is worth it's weight in gold...imo....

I had Zero breaches in my hull and I removed Everything in the hull except the hull shell itself.

Here is a link to what came in my Dewalt kit, there are a couple other offset cutting bits to get completely flat if needed. I used those to separate my deck from the hull in the transom well area. If memory serves...I think it was about $130

Not everything is junk. I bought it just to see if it would remotely work.

Fein is the original designer of these tools and I’ve had one for about 25-30 years. Cost a fortune back then and could only be found in higher end specialty tool stores. Originally bought for doing flooring to cut door jams, etc. Great tool with many uses. My original still performs like new.

Thinking their patent ran out cause now everybody makes them for a lot less money, even Harbor Freight has a cheap knock off of them.

It seems they all have the same blade mounting so all the blades work on all of them. Made getting blades and attachment accessories a lot easier.

[XstreamVking]

You can re sharpen those blades your self with a small triangular file. They cut better than new.

Thanks to all that have responded,I have most of the tools but not all.What I'm lacking is youth,and ambition.Not looking forward to the next chapter!

That will do some serious damage in no time.......:eek::D

[largecar91]

I use cheap menards grinders. The dust will eat them up over time

[nitro_rat]

Harbor freight grinders are too cheap. Last about 5 minutes each grinding glass...

[Instigator]

Yep.

I just replaced my 30 yr old 4" makita grinder thats bearings got sick of fiberglass dust.
And to those that like the lightness of a 4" grinder, they are gone. The stores have all gone to 4 1/2's so they dont have to carry abraisives for the small and large shaft grinders.

I even checked Harbor Freight and they had a 4" but w/the larger arbor.
I just e-bay'd another 4" Makita.

Also agreed on an air hammer w/a chisel in it. Hydrostreams outer skin is very, very thin though so be prepared fore some outer repair.

Agreed those things are vicious! Beware newbs to this tool, it commands as much respect as fire

I would never have even thought to use one for core removal, mine sits in a drawer and has only been used once, but with the glass and the wood it does make sense that this would eat it up fast.

[FMP]

And I was going to mention if you're good with a trimming saw, no bar oil.

[HydroSkreamin]

I used the 16 and 24 grit Zec wheels after using an oscillating tool for transom and core removal on my Eliminator.

I used a 4” Milwaukee, and borrowed a 7” Makita from a buddy. I got my own Menard’s 7”, and killed it. The Makita got recommissioned and is still running.

The 7” covers a lot of area and is controllable, the 4” gets into corners better.

I don’t suggest trimming your nails with either one!:D They have zero respect for skin or anything else they touch while rotating.

A friend of mine has one of these and it has removed the core in my Vulture and at least 3 of his boat and it still works awesome and makes for getting the job done a lot quicker! And I did eventually buy my own. I used and bought the 4 1/2 inch one. More than worth the money.

Hope that helps some.

Made in America quality tool....From the people that we get our glass supplies from....

That's exactly what I used to cut out the float boxes and old transoms I've done. It HOGS through 1/4" thick fiberglass like a beast. I just zap the blades quick with a tiny 3" air powered angle grinder to sharpen it up before use.

Youth and ambition...…. oxymoron !! You do fine, and the next ROMP is more than 7 months away! Merry Christmas , Bobby !!

[Deznuts3570]

I love my oscillating saw! For boat needs in general its awesome.

[outasite]

Thanks Nick!!
And again,thanks to all for taking the time to respond.

[outasite]

The oscillating saws are great. But my favorite tools are these for removing good balsa,I found nothing that came close.The "slick" is for peeling bark for log cabins.426273
