Man, don't you love a new tool?
Over the course of many years and many restoration type projects one of my favored but messy tools has been my home sand blaster. You've seen them. Small sand hopper with a screen cover on top. Twenty feet of feed hose connected to a small gun with replacement tips, (when needed). The sand blows nice and even and pits the working surface so nice and clean! Rust and old paint all but disappear before your very eyes. Once I realized how cool a blaster was and how cheap and small my existing air compressor was, it didn't take me long to go out and buy me a new high volume air compressor. Oh ya! This was cool and it worked great! The days of sore fingers and cut knuckles from hand sanding, scraping and wire brushing were gone! Old parts and old tools looked brand new again after a light blasting! Better than new in some cases. Once a part was blasted, just air off the excess dust and spray paint it right away. The fresh porous surface takes paint and holds it fast for the best finish I have ever seen. For years I've been messing up the side yard, spending money on sand, and getting it absolutely everywhere. In my shirt, down my pants, in my hair, and down my pants, in my ears, and down my pants. Ok, the sand is kind of a pain in the butt, (sand actually in my butt). Sometimes when running low on sand I would sweep up some of the excess sand from the ground and filter it back in to the hopper to be reused. This would blow dirt and cause clogs. Bad idea. I was always going to build a sandblasting cabinet some day. Something to contain all the mess and funnel sand back down to the hopper for reuse. I never made one that lasted or worked well. One day I vowed I would have a proper sand blasting cabinet.
Time marches on.
Well now I have the biggest project I have ever had in my whole life. Other than raising a family. "The River Queen Refit" This boat, being made from steel is just chuck full of things that could use a good sand blasting including the whole outside and underneath! I did end up blasting the bottom and sides when we were hauled out but I used a blaster the size of an African anaconda and had to hang on for dear life and limb. I know it's simple in principle but it sure seems like magic when you see stuff fall away as you wave your tool and bare metal remains in its' wake. To my dismay thin spots will blow through and leave a hole. It's just as well to know where all the thin spots are anyway so we can fix them! But does there have to be so damn many?
It's harder than it looks. Then add 100+ temps!
When good parts go bad.
If it's marine, it's expensive. If it's expensive, I try to fix it first, not replace it. But if you fix it, you damn well better fix it right or you can't trust it. It's of no good use to you if you can't trust it. Due to my tight budget I never replace anything that I haven't tried to repair or rebuild first. Granted, there are some things you just don't fool around with and should always buy new, like safety equipment, bilge and fuel pumps and head valves. Add engine room blowers and gas fittings to the list as well. Better safe than sorry. For some reason, probably the moisture, things on a boat get "crusty" yep. Covered with rust, film, crud, shit and piss, you name it. Now, if I were a wealthy man, (dream on), I would just toss any part that didn't pass muster right in the old dumpster and flip open my favorite book "West Marine Catalog" and order up! Hell with the cost. (God I wish). Here in the real world the part in question carefully rides home with me in the truck and goes to the bench for a few snap shots and illustrated notes. ( Tip- Always take snap shots and illustrated notes). The next thing we do is (and you do this too! admit it) is run down to the local hardware store and look for a reasonable replacement or facsimile. Almost always to no avail. Sometimes we feel we need to ask for help from one of the store clerks, and we seek out the oldest and most wisest looking gent in the store. In my case they know me on sight and hide behind something. When we finally find just the right person he'll "hmmm" and ask one or two questions. "What's it for?" (Same reaction for the auto parts store person as well). There are two words that will cause this person to stop dead in there tracks, give you an insulting look, make an excuse and head in the opposite direction. They are "Boat" and/or "Marine". After wasting all that time and energy you head back to the work bench and reevaluate the part in question. We might even look up the part in that damned catalog again, but the price is still the same. "Too damn much!" I guess I'll just have to fix the damn thing myself. That's what I'll do... "To hell with those guys! Remember, "It's a hobby" enjoy the challenge of it.
This dose that.
You ever bring a machine or part back from the dead? Very satisfying isn't it? I love it. I don't know where I get it from but I hope to pass it on to my kids. I think it may stem from when I was ten or so. My dad would bring home things for me to take apart. Not fix or put back together, just tear apart. He would provide me with several empty coffee cans and a bag of tools and say. "Screws this can, nuts and bolts, that can, electrical switches and connecters..." Well you get what I mean. He would bring me a wide assortment of things. Clocks, blowers and relays. One item still remember was an old cigarette machine. You know, I think dad still has the knobs to that old thing in one of his many drawers of spare parts. My dad is a man of few words. He wasn't using me to help him get spare parts, though I'm sure it was a plus to him. It was more of a self taught lesson in how things work. What's inside, and what tool to use to take it apart. Over the years I would learn to see things for their parts therein and not the whole unit. My first lesson in "back together again" was a two horse Brigs and Straiten lawn mower engine. We took that thing all the way down to its' smallest component. Cleaned it. Oiled it. Hand cut new gaskets. Hand lapped the valves. Made every small part the best it could be, and put it all back together again. To my proud shock and amazement, it started first pull. In doing this, I was able to see first hand the logic of the machine. The "this does that." and so on. The magic of the machine was revealed to me. To a good number of people today it is still vary much magic. To my sons I now teach this magic. I bring junk home to be dismantled as often as possible. Now I have a bigger collection of knobs then my father.
My second "together again" project was a motorcycle. Oooh! ahh! I was fourteen or fifteen years old and it was a nineteen fifty something Benelli 350cc street bike. Basket case. All in parts in box's. I was told by I don't remember who that the Benelli was sold by Montgomery Wards as a catalog item imported from Italy. My dad and I had a real puzzle on our hands in that old Italian thing. The foot breaks and gear shifts were on opposite sides then that of a American bike. In time we got it all back together somewhat but found that a small part in the kick starter was damaged beyond repair. A machined part. After what was an eternity to a fifteen year old, we found ourselves in the old "Niles Cycle Salvage" store. I remember my dad holding up the old part. About an inch in length. to show the rather rotund and hairy guy in greasy old coveralls the part needed and what it went to. After going to almost all the other shops in a twenty mile area we were expecting the "Never seen that before" we heard so many times before. This guy hmmm'd at it and reached over into a old salad bowl full of little odd parts, fished around for a second or two and produced an identical copy of the part needed. In perfect condition. I about fell over. My dad cracked one of his rare smiles and said "How much?" I thought this guy new he had us by the balls! I thought for sure he was going to gig us like a frogs in a pond. He flipped the little part to me and said "Ah, take it" Dad made him take two bucks for it but I knew that he knew it was worth way more than that. I think the real price for that part was the smile he saw on my face, and knowing that this kid was going to get the first real thrill of his life by getting a ride on his first big bike. Well we should have paid him double because it was my dad's first time on a big bike too.
That's me all right!
In 1974 I was a junior in high school.
This old bike had some real torque man. A one lung 350cc that could stand on one tire any time I wanted...
"My new tool!"
About a month ago I finally got my blast cabinet. Used, rusted and run down....of course..... but definitely a nice one, and....of course.... like anything I get my hands, on was properly torn down (including snapshots and illustrated notes). Cleaned, painted and pampered, back into first class shape. This was the easy part. The problem now lies in my once new air compressor you read about earlier. I'm not complaining mind you. This now old pressure unit has served me well for well over 25 years with hardly any service at all. (I'm bad about that). If I didn't do some preventative maintenance on it and soon, it would get ruined for sure. One compressor tear down coming up.
In the condition it was in, I could not believe this old girl could still work at all...I was lucky, even though the oil was low and looked like mud. The reed valves in the head looked like (searching of a word here) well they looked like shit. I was able to recondition all the parts and get it all back together again, (and work) And work good it does. I'm sure I was able to return it back to say 99% of it's original output and recover capabilities. Hell I think it runs and sounds better than it ever has! But I tell you what, I been running the piss out of her since we been back online. Hope she holds up.
It's a blast!
No really "A blast" This new blasting cabinet is real cool. Notice I didn't call it a "Sand blaster." Well it is in a way but as I found out, sand isn't the only medium you can put in them. On the label it says "Blast and Peening Cabinet"
"What the hell is this peening thing?" Peening I'm told is like steel shot. Small ball bearings. When you lightly hammer on the outside of a part you condense the surface molecules make that surface a little bit stronger. When you shoot small steel balls under pressure on a surface it's like hitting it with a bunch of little hammers making it stronger. It makes the surface look more finished as well as making it stronger by pounding down and rounding over the rough spots and deburring sharp edges.
My new blaster.
Blasting medium differs widely as well as the grit size. I know of sand, rock, glass beads and walnut shell. Yep, walnut shell. Good for removing unwanted paint but not the metal. Each different material with its' own blasting characteristic and will come in as many ten or more sizes. From a rough coarse size to powder so fine you would think it was dust. Currently I'm using a fine glass bead (#5) This would explain the big vacuum units that come with these blasting cabinets. The glass bead can remove rust and discoloration in hard steel. It really puts new life back into the old tools that look bad and cut through the crusty crap when inspecting for cracks in parts. The pattern for me has been - Blast, inspect, repair, refinish (File) re-blast, air off, paint. Done deal.
I love this stuff...
