http://igor.chudov.com/projects/ <P> This is a list of my various projects. One project that is not here for historical reason, is this <A HREF=/tmp/onan/Diesel>restoration and repair of diesel Onan DJE generator</A>. I am also publishing a collection of my PDF (and scanned image) <A HREF=../manuals/>manuals</A>. All files there are very descriptively named. Some machinery moving I did with <A HREF="http://www.machinerymoverschicago.com/"><B>Chicago, IL Machinery Movers</B>.</A> It took me a few years to accumulate this "portfolio" of projects. </P> <TABLE> <TR> <TD> en-us Copyright Protected 2020-01-06T02:55+00:00 webmaster@algebra.com webmaster@algebra.com 1901-01-01T00:00+00:00 12 hourly http://igor.chudov.com/projects/misc/Anvil <CENTER> <IMG SRC="-anvil.jpg" ALT=anvil> </CENTER> http://igor.chudov.com/projects/misc/Anvil/00-Purchased <P> I bought this anvil at Rock Island Arsenal from a liquidation auction. They decided to auction off entire contents of one huge building, because they wanted to renovate it. </P> <P> This anvil is 33 inches long and weighs approximately 340 lbs. I tried to measure rebound by dropping a 1 inch diameter hard bearing ball on it and measuring how high it would rebound. My best attempts at measurement ended up with rebound at 85-90%. <I><B>Update: after cleaning up the top surface, rebound improved to 90%</B></I>. </P> <P> This anvil came with a combination cast iron/wooden base. It also had a "shelf" that can be mounted in the pritchel hole. </P> http://igor.chudov.com/projects/misc/Anvil/01-Top-Cleaned-Up ./misc/Anvil/01-Top-Cleaned-Up http://igor.chudov.com/projects/misc/Anvil/02-Set-Up ./misc/Anvil/02-Set-Up http://igor.chudov.com/projects/misc/Anvil/03-Straightening-Chuck-Key <P> This Jacobs K5 chuck key was bent into a pretzel shape. I used an O/A torch to heat up the bent part, and my <A HREF=../>anvil</A> to straighten it. It took quite a while. It was very time consuming and, without counting cost of gas, I probably made $2 per hour fixing it. It was quite educational, however, to discover how metal becomes so malleable when heated. </P> http://igor.chudov.com/projects/misc/Anvil/04-Mini-Forge <P> This is a mini forge that I made out of six firebricks. It is usable to me for the little things that I am trying to do. The nice thing about it is that it is portable and inexpensive and allows me to work cleanly. It was also easy and inexpensive to make and the bricks can be reused. I used Oxy/Acetylene to heat it. </P> <P> The first test of this forge was restoring a rounded off hexagonal lathe chuck wrench. It was almost fully round instead of hexagonal. To fix it, I heated it up, upset the hex part slightly (made it thicker), and then forged the hex shape again. To make sure that it is the right size (1/2" hex), I inserted it into a 1/2" socket, where it was found to fit snugly after a couple of adjustments. </P> http://igor.chudov.com/projects/misc/Famco-4C-Arbor-Press <P> This is a 12 ton rated Famco 4C arbor press. It can be used in simple ratcheting mode, or in compound ratcheting mode (hence the letter C) in 4C. </P> <P> It had only one thing that needed fixing. The handle that is used to position the ram was broke. The cast iron hub had ugly remnants of cast spokes on it, and had a sloppy looking steel bar screwed on as a handle. It turned the hub on the lathe to remove the spoke remnants, and attached a spare star handle that I had for better appearance. </P> <P> Per <A HREF=http://www.famcomachine.com/arbor.htm>Famco Arbor Press Catalog</A>, Famco 4C is capable of 12 tons of pressure, is 35 inches high, and has 19 1/4 inch capacity over plate. Maximum 18 inch work diameter. </P> http://igor.chudov.com/projects/misc/Homemade-Brake-Die ./misc/Homemade-Brake-Die http://igor.chudov.com/projects/misc/Impossible-Wooden-Block-Tower <P> My 6 year old son built this structure with three supporting columns on the bottom. When time came to destroy it in a spectacular fashion, I suggested pulling out the middle column so that it would crash inward. He did just that, but it did not crash. I have no idea how it may be still standing, but photos prove that it did stand! </P> <P> There are absolutely no hidden gimmicks, chewing gum secretly holding things together, etc. </P> <P> <B>Important! if you want to submit this page to Digg, this is a SLOOOW connection!

SNS45 by default works in automatic mode, sometimes shooting more than one staple at a time. This may be useful for roofing contractors, but since I use it for building crates, it was annoying. </P> <P> <A HREF=http://senco.com/>Senco</A> offers a replacement trigger free of charge, due to legal and safety reasons. They sent one to me, but I found the instructions to be rather lacking. This page attemps to go to another extreme and offer a photo tutorial for replacing the original trigger with a restrictive one. </P> <P> One of the most important troubles that you may to encounter, if you are like me anyway, is that you would be unaware of a spring in the back of the magazine, that pushes magazine cover and forces it to close. It is very easy to lose that spring by accident. Do not lose it and pay utmost attention to it while disassembling. Do not forget to put that spring back. There are two recesses in the back between which the spring operates. </P> <P> <A HREF=07-Mag-Detached.jpg.html>One of the pictures</A> (see annotation) shows where the spring that Senco supplies in the kit, goes. </P> http://igor.chudov.com/projects/misc/LW-CHUCK-CO-Dividing-Head ./misc/LW-CHUCK-CO-Dividing-Head http://igor.chudov.com/projects/misc/Miller-XMT-300-CC-CV-Repainting ./misc/Miller-XMT-300-CC-CV-Repainting http://igor.chudov.com/projects/misc/Painted-Famco-3R-Arbor-Press <P> This press, when I bought it after answering a Craigslist ad, looked as bad as you could imagine. About 3/4 of paint was flaking off, looking like a dirty pig's body hair. I think that this is a result of a bad spray paint job a few decades ago. Besides that, however, it was in a good condition. </P> <P> To clean it up, I used a cup brush mounted on an angle grinder, and for hard to reach areas, an air powered abrasive blast gun. </P> <P> <A HREF=http://www.famcomachine.com/arbor.htm>Here's the link to Famco's press page</A>. Data: Press #3-R, Diameter of work 15 inches, Capacity over table 12.5 inches, capacity over plate 11.5 inches, Leverage 60-1, Tons pressure approx. 4, Height 21.5 inches. Bolster plate A3-05. $132.30. <P> For the primer, I used McMaster's "cold galvanizing" paint with 94% of zinc by weight. On top of it, I used a "John Deer Green" oil paint. </P> <P> I also added the red handle that you see on the end of the lever, it had a 3/8 NC thread that I drilled and tapped in the extension bar. Besides that, I milled a groove in the tooth that ratchets, to make lifting it up easier to do with a thumb. </P> http://igor.chudov.com/projects/misc/Painted-Famco-3R-Arbor-Press/Hydraulic-Assist <P> I bought the smallest hydraulic jack at Harbor Freight to increase the force of the press. My estimate is that when the jack is pumped with moderate effort, with only a half of the handle (the handle can be assembled to be twice as long as on the picture), the arbor press produces approximately 10 tons of downward force. </P> <P> As a gauge of force, I used a small bearing ball between two mild steel plates. Without the jack, the ball would only make small dents on the surface of those plates. With the jack, the ball fully sank and the distance between the plates was reduced to almost zero. </P> http://igor.chudov.com/projects/misc/Repainting-Of-Wilton-500S-Vise <TABLE> <TR> <TD> <P> This is a <A HREF=./-Wilton-500S-Vise.jpg>Wilton 500S machinist vise</A>. (500S means 5 inch jaw, Swivel base). The vise is a work of art in itself, made of 60,000 PSI <B>cast steel</B>. While it did not look too bad to begin with, I decided to replaint it. I first thoroughly cleaned it, degreased, degreased some more, wire brushed it, degreased some more and wiped thoroughly. I also milled off a small layer off the anvil to make it smooth. Then I applied a "cold galvanizing paint" that is extremely durable. On top of that, I used a spray oil based enamel as a red paint. </P> </TD> <TD> <A HREF=./-Wilton-500S-Vise.jpg><IMG SRC=./-Wilton-500S-Vise.jpg ALT="Wilton 500S Vise"></A> </TD> </TR> </TABLE> http://igor.chudov.com/projects/misc/Rotary-Converter <P> Pictures of rotary converter from <A HREF=http://www.irm.org/>Illinois Railway Museum</A>. This rotary converter converts AC to low voltage (600V) DC to power train and streetcar engines. </P> <P> See third picture for <A HREF=Rotary-Converter-0056.jpg>details</A>. </P> http://igor.chudov.com/projects/misc/Rotary-Table-Crank-Handle This is a handle for my rotary table. The original handle on it is very inconvenient and I always wanted a better one. The knurled knob on the handle rotates freely. It is made out of a 1/2" Armstrong wrench, which I had to bend to provide a more pleasing shape AND clearance to clear various obstructions on the table. I bent this wrench red hot, which accounts for nice curvature. http://igor.chudov.com/projects/misc/Toy-AK-47 ./misc/Toy-AK-47 http://igor.chudov.com/projects/misc/Troyke-Rotary-Table-Disassembly <P> Pictures of disassembly and reassembly of a Troyke DMT-15 rotary cross-slide table. </P> http://igor.chudov.com/projects/misc/flatpanel ./misc/flatpanel http://igor.chudov.com/projects/misc/instant-chess <P> Extravagantly complex and yet brilliantly simple, chess is a game riddled with millions of puzzles. With every move, the amount of strategy increases exponentially, and our human mind searches for a path through this ocean of possibilities. The way each person navigates through a game is completely unique to how they perceive the chessboard. Chess is a beautiful representation of one's consciousness on a physical plane. By examining our games, we can observe our strengths and weaknesses, and through careful study we can improve our strategies and change our perception of the board and possibly life. </P> <P> Chess is a very important part of my life, and <A HREF=http://InstantChess.com>InstantChess.Com</A> provides me with an irreplaceable service; I type in my name, press enter, and am instantly placed in a game. The board is easy to see, pieces are recognizable, and service is very fast. Other online providers that I have tried can be very frustrating; one must try dozens of different tables in order to find an actual game. Moreover, <A HREF=http://InstantChess.com>InstantChess.Com</A> works more reliably on my computer than other providers. And I always prefer to support a small business than a multibillion dollar corporation that offers chess to advertise its corporate products. </P> <P> -Max Perhunkov </P> <CENTER> <IMG SRC=./-chess.jpg> </CENTER> http://igor.chudov.com/projects/powerwasher <P>I bought this powerwasher used from the US military. I suspect that they wrote it off because the gas line from the tank to the carburetor was leaking. I replaced the line and the engine started on the second pull. It is supposed to be a bad ass power washer, up to 3,000 PSI, with the Briggs and Stratton 11 HP Industrial/Commercial engine.</P> <P> <B>First Question</B>: the engine goes faster and slower every 6 seconds or so, maybe varying speed by 30%. Why would that be the case. </P> <P> <B>Second question</B>: how would I regulate water pressure on this beast? </P> <P>Pressure 3000 PSI, flow 4 GPM, washed model # 0w3004MGD.
