ThermoFin attachment idea

In a previous life, I built heavy duty saws for the picture frame and window industry.

Alot of the machines were designed to cut mitered aluminum frames, 12-18" saw blades at 3400 rpm - makes ya stop and think.

But anyway, those aluminum machines would get a spray attachment of atomized water soluble oil. This lubricates the blades and keeps the blades sharper longer.

You can easily get this and use a spray bottle. Every 2-3 cuts, just a couple of sprays. The blade will keep 2-3 times longer.

    The lack of

    pre-drilled holes has been a bit of an issue with these heavy extruded plates. I have tried a number of different methods for nailing and screwing them up.

    Automatic, self feed screw guns still seem like the quickest, best attachment. However the aluminun chips tend to jam up the feed mechanism when working over head. Also the screws tend to thread the plates and push them away from the floor sometimes.

    I used my table saw to cut these slots for screws. It also allows some expansion room.

    Quick and easy to do. Wear ear plugs and a face shield, set the blade real shallow and be careful.

    slots

    hr,


    Have you tried your D Walt cut off saw to cut the slots?

    Now if

    you had a small plastic sleeve that would help limit how far the screw went in you could get a tight screw and at the same time micro space for the Thermo fin to move. Sholdd move quitely also. Just a guess bigugh

    Good idea

    I did cut all these ThermoFin to 2 foot lengths with the Dewalt dry cut. In all honesty my 10" miter saw with a non ferrous blade leaves a nicer cut than the dry cut blade. Same with copper tube. Here is the difference between the two cuts.

    I suspect the dry cut blade is more multi purpose while the non ferrous blade is specfically for aluminum.

    I certainly am not going to give up on the Dewalt dry cut. It's the SUV of saws in my opinion, a fine addition for any plumbing/ heating shop.

    I started a fad...

    2 months ago, no one on the big job site I'm doing the snowmelt on had ever heard of a Multi-Cutter Saw.

    Thursday, when I was riding my bicycle around all the trades encampments on the job site looking for a push broom of mine that had suddenly disappeared, EVERYONE had a Muli-Cutter saw.

    Funny how that works.

    You're right HR, after having used it for a couple hundred cuts on 4,3 and 2" steel, it doesn't cut the 4, 3 and 2-1/2" "L" copper as clean as my copper only saw cuts, but it is still the bees knees.

    Nail guns

    I thought you were using a roofing nail gun to attach them?I was thinking of giveing that a try on our next staple up.

    I know exactly what you mean about the chips,but haven't had a problem with them pulling away.Maybe I'm useing a different type of screw.

    Hey, John!

    This batch of plates is for a metal ceiling I am trying to turn into a panel radiator :) I found they attach better if pre -drilled, punched, slotted, or whatever!

    Otherwise the roofing coil nailer would be the weapon of choice.

    I demoed a stapler once, it seemed to distort and buckle the plates a bit more than I liked. It seemed to effect the contact "patch" The coil nailer works fine, a little more $ per shot than a stapler, pennies really.

    Demo a few staplers before you buy. Some of the less powerful ones (narrow crown finish staplers) would not shoot through the Thermo Fin heavy plates, I discovered. The staples would buckle up and jam the gun.

    Staple

    We have found it easiest to staple up Thermo-fin with 3/4" staples using a pneumatic stapler. I've had too many problems with screws falling out after a year. I haven't had any stapled jobs fall. Now if I could just get my competition to understand the benefits of plates.
