The Shop

Welcome to my shop.

Always looking for something cool to build, My roof tear off tools are a favorite among many such projects.

Although the roofing tool production line is hacked out of bedrail and lawnmower parts, it produces a fine-crafted, high-performance roof ripping tool at a decent price, and all the jobs go pretty slick.

Have a look around, there's plenty of cool butchery going on. Perhaps a project will be inspired or aided. Enjoy the fine art of hack Tear off tool production line

Roof Ripper Production Line

Heads Top
roof ripper close up

It can't all be hack. A well crafted roof tool needs some accurate parts.These are cut by my C-N-C abrasive water jet cutting service, Wet Jet Precision out of Utah. Their parts are tight, and their service is awesome. cnc cut roof ripper parts
cutting roof ripper rip barbs

A wantonly altered plate shear cuts the rip hooks for the hand version of the roof shingle stripping tool. I can get her cutting a part a secondvideo of cutting barbs for the tear off tool.
 drilling roof ripper barb holes

The holes for the hand powered roofing tool’s ripping hooks are first drilled several at a time, which saves big on deburring. This jig is big-time hack, but it turns out a nice looking batch of parts in a short time.

The jig is tricked-out to make all of the welding on the shingle stripper toolhead easy.
truing up the roof ripper head

Both the powered roof shingle remover and the lightweight hand tool get a light planing, so they're "pre broke-in" for full tear off performance on the roof, right out of the box.
Bracing the tear off heads for quenching

The shingle stripper's teeth are braced for the quench.
austentizing the roof shingle tear off heads

The roofing remover tool heads are austentized in my homemade forge and then quenched in water.

Then it’s twenty minutes in my homemade tempering tunnel to complete the heat treatment on the roof shingle tool heads.
Ferrules Top
cutting ferrule blanks for the roof ripper

The hand version of the shingle stripper gets a ferrule so we can weld the steel head to the wooden handle. A sheet is chopped into strips at the steelyard, then precision blanks are cut on my tricked-out plate shear.

The other end of the powered shingle tool’s shaft gets an attitude adjustment with a two-handed grinder for a nice deep weld.
quenching the powered roof shingle stripper's shafts

The shafts for the air powered roof tear off tools are austentized in my homemade forge, then quenched in my homemade water-cooled oil bath.
tempering the power stripper's shafts

The shafts then spend an hour in the homemade tempering tunnel. They are drawn only slightly at this time. Selective tempering will be applied after the power stripper's tool head is done being welded.
Hand Tool Mounting Top
fitting the tear off head to the ferrule

The hand version of the roofing remover tool has its tool head fitted up to the ferrule. First, two tacks while on the jig. Then each piece is inspected for alignment before being blasted solid.

power ripper tempering colors

We need pry-bar properties in the high-stress areas of this powered roof shingle remover. Heating to an upper blue has been yielding good performance while tearing off roofs.
Power Handle Modifications Top

The stock air tool gets stripped to the frame, stuffed with a rag, then the bevel is carved with the two-handed grinder. this helps guide thepneumatic tear off tool under the roof shingles.
extending the handle on the pneumatic shingle remover

Two less pounds of weight and six more inches of reach are some sweet on the roof, especially for the steep/staged roof shingle stripping jobs. Most of the air powered stripping toolís heavy handle is hacked off and replaced with lighter material. A couple of butched-out jigs ensure nice allignment.
Finishing Top
painting the foor shingle tear off tools

What can I say? Two seconds into a shingle removal job and whatever finish is toast! We’re not paying for anything fancy in the paint department here. Bombs are good, cheap bombs are better. They’ll retain their factory look about long enough to get up on the roof

Contraption Close-Ups

Heat Treating Top
Forge used to heat treat roof rippers

The propane forge (top) is used in the heat treatment of the roof shingle removal tools as well as other projects. It features every imaginable adjustment and folds down somewhat for storage.

She’s a fine piece of butchery, bed rail and re-rod woven to fire brick and propane. Set me back a light hundred.
oven for tempering tear off tool parts

The tempering tunnel(top) fine-tunes the heat treatment of the roof remover tools. It features plenty of power, and brain-controlled elements for steady heat. Accessories include a tray for general tempering and a drop-in conveyor beam for shingle stripper tool heads.
another view of the tempering tunnel

If this isn’t the ultimate in hack, it’s gotta come close. She started life as 1 1/2 side-loading toaster ovens, whereupon she was ripped open, muzzled shut, flipped over, tacked down, and run through. Scabbed up a heat shield with the first thing that came in hand and splattered the brains out onto her.

She’s actually a smooth-running rig. Ran me a light hundred and has since tempered hundreds of parts.
quench bath for the power shingle ripper shafts

The water cooled oil quench(top) hardens the power roof stripper’s shaft. The 1/4" copper coils are non-schedule soldered to the 3/4" copper manifolds. This heat exchanger drains into the water quench tank, which feeds the pump. The water quench tank is a mechanical scale trap and keeps debris out of the radiator.
full heat treating line for roof shingle ripper parts

The roofing tear off tools are first fired in the forge, then quenched in the bath. A small area on the tool part is cleaned to shiny metal before going through the tempering tunnel. This way, the tempering colors can be read upon exiting, so we know the steel is cooked right.

Much of the heat treating line(top) is covered elsewhere. Here, the bath cooler can be seen bodged together out of a FHW pump, a truck radiator, and a house fan. The water quench tank is actually a mechanical scale filter (trap). A line log is kept so that we can get in-spec. roof tool parts right from start-up.

The shafts for the air powered roof shingle removal tool are quenched in oil.
Cool Shop Contraptions Top
this lamp helps buid the roof tear off tools

The machine lamp(top) is an arm-mounted halogen fixture on a fully adjustable base. It features the ability to put the light right where you want it. It has been very handy for fine work, painting, and photography for the roof stripping tools and other projects.

This one was scabbed together when the boss wasn’t looking. I had to make one nice cut, but the rest was all hack. None the less, she’s light-weight, well-mannered, and has served well.
cam lift mechanisms

The cam lift mechanisms(top) enable a table or machine to be rolled into position, then set down on solid feet for thrashing out the work.

The welding table has a camshaft under each end, while the band saw only needs one up the middle. Handy for setting up repeat operations for the roof shingle tear off tools or other projects.
another lift rig

shear for cutting roof ripper parts

This 8" discount plate shear(top) has paid for its self many times over with thousands of cuts. Powered by a four foot lever, it features about 3/16" capacity and an infinite throat for long cuts. She was in the bottom $100s from Enco.

Put the gas axe to her before she made her first cut and butched off the cheesy hold down bar in favor of a platen and clamping beam. A micro-adjustable back stop was later added when the roofing removal tool required it. The platen system is also handy for clamping on jigs for repeat operations for the roof shingle tear off tools and other projects.
Other Cool Contraptions Top
how to weave a solid newel

The rock-solid newel(top) post is sturdy enogh to stop a stumbling human and will last for years.The trick to a solid bottom newel post is weaving it onto the SECOND stair riser and the full girth of the stair stringer. This is opposed to the traditional practice of merely using the tip of the stair stringer, which loosens up after a short time.

Run that SECOND RISER on by, then notch the 4x4 around it. Nail both the riser and the full width of the stair stringer to that bottom newel. That's pretty rugged already, but you can overkill it with bottom or back straps. Full plate the bottom if you're setting on dirt.

Driving around, I see a lot of loose, crooked bottom newels on exterior stairs, so I hope this helps. It is a contribution to my fellow framers in much the same way as my roof shingle removal tools are to my fellow roofers.
Trebuchets Top
brick launcher

The brick launcher(top) was my first trebuchet launching a brickbrick throwing trebuchet 120 yards downrange. Impressive, but cumbersome.
egg launcher

The egg thrower(top) came next, throwing an eggegg launching trebuchet 100 yards. Easy to transport and load, but not as impressive.
can throwing trebuchet

The can crusher(top) is high performance, but temperamental. When it is running righttrebuchet throwing a can, two guys can put a 12 oz can of soda 100 yds downrange every 45 seconds and have it packed up in two minutes.

steam experiment

This steam experiment(top) was to test the viability of building a steam engine and runs on compressed air. An all-out butch job, it is kinda fun to watch it run.
pedal boat

The pedal boat(top) was just another cool project. It runspedal boat in action ok.
automatic coal stove

This attempt at an automated coal burner(top) seemed way too complicated and never did work too well, so it ended up getting cut down into a plain-old barrel stove with all the automation stuff sent back to the junkyard from whence it came.

It was good practice though, both in general building and in the burning of coal. It was found that the forced air chamber did not produce a fluffy ash, but rather a slag. Hook up a gas engine to that shaker grate, but that gook ain’t going nowhere! At the same time it was discovered that fire-brick can be melted, which I consider to be an excellent hack. See it run
babington burner experiment

The babington burner(top) was built, or rather mocked-up to be sure that we could consume vast amounts of waste vegetable oil should we be successful in its acquisition (which we weren’t). The first mock-up made a very nice flame, but had messy emissions. After a few day’s practice, we achieved a wonderfully clean burn with this later incarnation.
wood chip burner

This biomass burner(top) (wood chip) is based on the FEMA-style stratified downdraft gassifier. After about seven re-modifications, I got the first decent run out of it.
