Thanks for all the advise, much appreciated.
Colin,
I had been thinking of this method, but decided to use the Excel, again to get experience using it.
Nobby,
Did that yesterday when I had the jaws on the Excel holding files properly, then had a go on a piece of scrap.
As you say, the job would be all over the table without the arm preventing it jumping back.
Must try without the arm just to see what happens.
Will put a photo of the machine up, as I need thoughts on why the file support and hold down arms are fitted as they are.
Rus,
Life is just too short to start to learn and equip for blacksmithing, although I would dearly love to.
Have the books, as I was planning to do so in a previous life

You mention carbon steel, annealing and tempering, but what about plain MS for the spanner?
The handle is just for moving the ram to check clearances and moving the table, so no force applied.
Will take photos of progress/process and add them to my album.

I decided to go the audio book route as my back felt as if had been pummeled by some heavy weight boxer. All I did yesterday was to sort out the Boxford spanner and handle material and then the Excel file clamping jaws that weren't closing onto the file shanks. Oh, I did take the table off of the machine, but it isn't that heavy. I have, however, learned to my misery that just turning whilst holding something of weight can throw my back out, but yesterday it was just general aching all over, and perspiring as well.
Getting bl**dy old and big C treatment I listen to Internet music stations via my 6 year old iPod plugged into a Bose dock, and that's more than loud enough. Geoff - Coffe then workshop |

Seeing what you put at the end of your other post use the shaper to cut each corner in turn. I'd rather get the spanner and handle done quickly, plus I'm just not confident enough to even try this yet, but thanks for the suggestion. I need to become familiar with the workings of a shaper before tackling something as 'delicate' as squaring a round hole. In a year or so I may be up to doing as you suggested. Geoff - Coffee finished. Workshop or Audiobook now? |

How about drilling a round hole and filing it square? am I missing something? Very useful tool the simple file Not missing anything Chris. My thoughts as well, except machine aided, not muscle driven. The Excel should take this in its stride, and it will give me an opportunity to become familiar with it. Geoff - Coffee time |

Fizzy, You are now going to be amazed at how quickly she grows up and how she picks things up and tries to communicate, all without any spoken language yet. DO take lots and lots of videos of her as she progresses. It will bring both laugher and tears of joy when you both look at them later on. Other half watched a video she didnt remember I took, of GD trying to alternatively bite her big toe (SHMBO's not GD's) and put a flip-flop on, with squeals from Iwona and laughter from everyone else. The number of times I haven't had a camera handy and missed a peach is growing longer. GD loves my iPad as things move on screen when she swipes her hand across. Other half was visiting and saw Agatka (GD) trying to achieve the same with Dad's Kindle and getting nowhere fast. She tried poking everything on the device, turned it inside out with no response, and getting more and more annoyed in the process and actually huffing in the process. How I wish I was there to video it. May take my Kindle and see if I can get her to repeat the performance. Geoff - "Enough waffle, finish your coffee" from the Boss. |

Not fit for purpose! Reject it. Bad bad design as already stated, so DON'T be tempted to rectify it as you won't know what else is thrown up afterwards. Something at that price should perform as advertised. No wonder you have lost confidence in it, I would as well. Geoff - Ready to make Boxford shaper tools. |

I need to make a square holed spanner for all the square bolts, as well as the ram pulley operating handle. At present I'm using vice handles, but they are a compromise at best. Advise please on the easiest way to make such. I have just refurbished an Excel filing machine I bought late 2006, so that could be used to square drilled holes. Handles are easily added. Geoff - Carport leaks fixed! I hope that is. |

Congrats to you and better half! Watching her grow up will be one of the wonders of the world. Other half and I have been watching grand daughter the past year, and it really has surprised us at how quickly she learns, and now beginning to test parents and ourselves. Must be something to do with evolution or whatever. Both of you enjoy and take plenty of photos and videos!
They grow up much too quickly, or is it just us getting older quicker

When I converted my single brick garage that's attached to the bungalow, I gave the brickwork three coats of a vapour barrier, fastened 2x4s to the brickwork forming a framework, 2" EPS between said framework then Stirling board over that, painted white, as is the floor. Before doing so, the garage would either be boiling in summer or freezing in winter. Now, however, the temperature gets no lower than 5° overnight and in summer no higher than 10-15° no matter what it is outside.
Heaven Surprisingly humidity appears absent, as nothing appears to be rusting now, whereas before it was a constant battle. Insulate, insulate, insulate to anyone contemplating such, you won't regret doing so. Geoff - Time to fix carport leak. |

Woohoo! It's up & running (with reservation as I've detailed at end of post) Photos added of the process of getting the motor & countershaft assembly installed. I decided to use the BMF motor instead of the TEC one, as the bigger one has mounting feet with enough adjustment to get the correct belt tension. Using the TEC would have been a PITA getting it mounted so have put it aside for future use. After much thought that included studying the the motor compartment as well as various ways of lifting the motor/countershaft assembly, I decided to make a sling to lift it up. The shaper has very convenient lifting holes front & back, and passing the rope through the rear ones, suitable secured on the left hand side, brought it in front of the motor so that it took the weight on the motor platform, through the right hand hole, I was then able to heave the whole unit up high enough to get the pivot bolts into their respective slots, having secured the rope round the belt tension lever. (Edit: Must remember to tighten the pivot bolt lock nuts!) Couldn't quite believe how easy it turned out, after the obvious off day I was having taking it all out, but it does of course help understanding how it actually goes together in the first place. I did think of using a scissor jack to help lift, but that was more hassle than worth. Everything else connected up without a problem and time came to get it powered up, after oiling all parts required. Then the hunt was on for the longer V-belt I had just purchased. Could I find it, could I heck. Lounge, office, carport & garage twice revealed nothing. Then I remembered a length of Twist&Lock belt that came with the lathe, and it was the perfect length, so on it went. Hooray. Switched on, twiddled the pot and nothing! Nada. Not so much as a hint of moving! After certain Anglo-Saxon words has been said, it was time to investigate. Up till then, I had only moved the ram using arm power by way of a vice handle on the pulley drive. I decided to loosen the gib adjustment screws and the machine was off and running. I did a suitable jig whilst watching the ram move smoothly & freely after who knows how many years of inactivity. Oil was then squirted at regular intervals along the dovetail on each side of the ram, with black gunge eventually being squeezed out to run down the front and rear. I suppose I should have removed the ram to clean all the parts first, but didn't, as moving the ram by hand it felt quite free. I must have used more force than realized. Eventually the dovetail oil became clear, and I let it run for about 15min to ease things. This all took place on Saturday. Another look for the errant V-belt on Sunday morning found it snuggled up against the compressor where I had no doubt pushed I out the way. I had, by then, ordered another! Oh we'll.
Today I decided to adjust the gib, & that's when things started to go wrong!
The bolt holding the Crank gear sliding block kept coming loose,
I had made the gib a tad too tight, so slackened the grub screws off once again.
This bolt is threaded all the way up to the head, with the threads that pass through the sleeve, on which the sliding block moves, having been crushed, which may have just happened, I don't know.
It looks original though, having a square head.
It really has to be pulled up tight, but has still worked loose a couple of times. There is a spring washer under the square head shoulder.
Any suggestions appreciated.
Geoff - Champing at the bit to start shaping. Still can't believe it's ready to do some work

Thanks Jason. Managed to find your solution whilst you where posting. At first I went straight to Add Photos instead of going via Edit photos as you pointed out. Geoff - Will update my Boxforf/VFD post now. |

Need help please. I'm unable to upload additional photos to my Boxford Album, showing how I managed to get the new motor and countershaft installed. Won't add to my original post about this until I can get the photos up. Went through the same procedure as with the first photos, but now nothing shows up. Is there a limit on size that can be uploaded? Geoff - Puncture could be a leaking valve.

Having done drawings myself, it's all too easy to forget to add details sometimes. Wanting to get the drawing finished, to move on, sometimes makes one forget things, like checking! Only experience will fill in the holes, and asking on this Forum. Moral: There is no stupid question, other than the one one keeps asking. Geoff - Getting ready to change wheel on car. |

I fitted a Newton Tesla to my Warco BH600G lathe. Could never go back to belt changing now. Did the same on my drilling machine. The ease at which you can adjust the motor to get the perfect speed makes you wonder how you managed in the past. Don't hesitate, fit one! Geoff - Still working on the shaper |

Another search found the Operators Handbook at: http://www.neme-s.org/Shaper%20Books/Boxford%20Shaper/Boxford%208%20Inch%20Shaper.pdf with the following info on motor rotation :- "The motor and countershaft pulley should rotate in a clockwise direction when viewed through the drive compartment door." Now to gird the loins for some heavy duty lifting in a confined space.
Geoff - Too relaxed to do the heavy lifting now

A quick search has found this: "When the ram is moving forward the slide block must be in the upper section of the yoke and when the ram moves backwards, the slide block must be in the lower section of the yoke." Confirmation please. Geoff - Still relaxing |

Cannot quite believe it, but after getting the shaper mid 2006, I'm now ready to get the motor into position & switch on. Both the drilling machine & shaper motors have been connected to the common VFD, machines operated one at a time through a selector switch, and tested. Before I strain the muscles though, does anyone know which way either the 4-step pulley or motor should rotate please. Geoff - Time to relax |

As Clive mentioned, don't make moving parts with too tight a tolerance.
That's why locos with what appear to be totally worn out moving parts/joints work without any problem.
I've heard miniature locos clanking around the track, due to wear, but still performing quite admirably.
Reminds me of a customer who was building an Allchin and who got tolerances so tight, he scraped paint off when doing final assembly.
I don't make sliding/rotating parts a push fit on miniature locomotives, and that philosophy has stood me in good stead over the years.
Too tight a fit could/would induce binding/lockup.
I will be making easy fits on my 4" Little Samson, with exceptions of course.
Geoff - It's sunny!
