We're wrapping up an engine transplant into this Tique and the couplings won't mate. We've had 2 prior engines in this boat without this problem, but with this recent Commander, the nut that holds the transmission coupling protrudes a bit more than usual and the key on the shaft coupling protrudes out just enough to hit the nut and not let the faces of the couplings touch. I've tried persuading the key to move back, but it won't budge. Anyone have any ideas short of taking the coupling apart and putting it back together so the key doesn't stick out past the shaft? The alignment is almost perfect, but you can get a .008 feeler gauge around the entire surface.

Get your Dremel tool out Bruce.use a cutoff disc and grind that key down if that's all that is stopping it from going together. Dremel tools are must have life saver. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Years ago, I always thought the Dremel was for the hobbyist. Not anymore!!! They aren't the best built consequently I'm on my 3rd one. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| I guess I'll be buying a dremel tool. I didn't realize they would work on steel like that key. |

If you have an air compressor available then you can go to Horrible Freight and get a cheap air cutoff tool that will do the job Years ago in the Die building business we would use a tool called a Dumore grinder. Like a Dremel but built to take it. Then air tools came along and changed things. ------------- Keep it as original as YOU want it 1978 Mustang (modified) |

Bruce, Go for it!! Duane's suggestion is a good one but then you need to haul the compressor around. I worked side by side with tool makers for 16 years and they actually preferred the cheap Dremel electrics. Less bulky so they will get into tight spots. There were times they would actually use them for touch ups when the dies were still in the press. When they go, you toss them and get another. Just get the basic kit without all the fancy attachments. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Pete is correct, My Dremel tool gets more work with every job I do. A Dremel with a cut off wheel will cut through that old keyway in about 30 seconds and your done. The Dremel will spin at up to 30,000 RPM and if your cutting wheel comes apart it can bring real danger to your eyes. Wear eye protection and wrap up your project. They can cut through a hardened bolt so nice you don't even have to clean up the treads to use the shortened bolt. ------------- |

Bruce get some extra cutoff discs while your there,you can break them easily. http://imgbox.com/fTf3dwFP" rel="nofollow">  ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Bruce, I suggest the EZ lock over the screw on that Gary posted. Yes, the HD has them!   ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Not really Pete. I always use an "air hose" between the tool and the compressor. Really handy item to have. You need to join the modern world. ------------- Keep it as original as YOU want it 1978 Mustang (modified) |

Well, as long as we are talking the HD, they have the bulk pack too.  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Bruce, I think the cutoff wheels are the most used tool I put in the Dremel. I remember the years I fought with rusted or seized bolts. They zip right off with the cutoff. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| The Dremmel worked great. It brought the key right down and the flanges went right together. |

Bruce, Great! Next time you run into a rusted or seized nut/bolt, remember the Dremel. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Duane, I'll take you up on the suggestion but I need to go shopping for a project I have down in the boat house. What do you think the pressure drop would be down at the boathouse for 1000 feet of 3/8" hose starting at 150PSI in the shop. There is power down there so the alternate is hauling my portable "pancake" compressor down there but I worry if the 15 amp circuit would hold. Which way would you go?  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

[QUOTE=8122pbrainard] What do you think the pressure drop would be down at the boathouse for 1000 feet of 3/8" hose starting at 150PSI in the shop. /QUOTE] Zero psi drop till you start the flow of air. Depends on cfm usage. (you knew that) edit btw: you have added 5.73748174 gallons of air to the system with that much hose ------------- Keep it as original as YOU want it 1978 Mustang (modified) |

If I thought you were serious about this then I would send you a layout showing how to use a reserve tank at the boathouse and still be able to use your 1000ft. air hose Why only 15 amp service?? Surely that was not run 1000ft also. You will need to buy a VOM and check your voltage drop ------------- Keep it as original as YOU want it 1978 Mustang (modified) |

Duane, Ok, now you want me to go out and get a reserve tank too and I'm sure you would recommend an ASME rated one too! Running some pressure drop calculations, it looks like I could use the 3/8" hose and see about a 2 PSI drop. I could live with that but, the CFM is bad. Using a 13CFM, die grinder, looks like I'd be down there all day waiting for the reserve tank to refill. Regarding the electric, it was run for lighting back in the 30's when electric was run to the house. (in laws house). A 10 amp load on the 12 gauge is about a 30 volt drop and that won't run the compressor. I'm just going to take my Dremel down there! BTW, I'm very familiar with reserve air tanks having laid out 600 HP of sequenced compressors in a 200.000 sq. ft. blow molding plastic injection plant. We installed 3, one in each corner of the plant. It works! ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I suspect the remote tank would be a viable solution at hat distance if you keep the fittings true 3/8 pipe ID and keep QD's out of the plumbing until the tool. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing."

Hi Duane This seems like the perfect place to say that you were so right the other day. I'm sure you remember the conversation
