    Sorry to read about the luck of the draw Nick, hope your recovery is smooth sailing. Cheers Tim

    Drive shaft shortened to replace Rotoflex?

    I am not planning on altering the hubs or bearings , though it is worth considering.

    Drive shaft shortened to replace Rotoflex?

    I decided to work with the Datsun sliding axle but with a slightly different modification. I've shortened the stub axle and machined a serrated spline on the former rotoflex end, added an original yoke from the opposite end of the axle. This yoke attaches directly to the slider portion of the Datsun axle , the Datsun yoke was removed and a centering bore machined in the butt end. The rest of the Datsun axle, unmodified, is to be bolted to the existing diff flange via an adapter. That slider portion has nearly 2" of travel . Picking up the spline without an involute gear cutter, just a carbide endmill. Successful marriage to the newly splined stub axle. Mock up and measurements prior to welding an adapter to the slider tube end,

    Drive shaft shortened to replace Rotoflex?

    Yes, I would agree with that, I am thinking of using the later Spit propshaft with the cylindrical opposed bearings. Combined with a shorter Spit damper mounted on the frame it would in theory limit the extension range and prevent fouling on the chassis. I don't know if in practice that is a good idea. I will mock them both up to see where everything falls. Ive made up this device to preload the spring and give me some reference to movements and position.

    Drive shaft shortened to replace Rotoflex?

    Hi Steve , good to hear from you. I too, don't really have an issue with the Rotoflex, other than the unreliability of the replacements offered today. For myself I am content with the stub and hub assembly, would be nice to have a larger inboard bearing as you used though. My thoughts are the sliding spline from a GT6 driveshaft is actually quite small in diameter,13/8" compared to the Datsun. I don't want to hack up the frame for clearance, so maybe I'll thin down the mount bushing on the diff to tilt the front Of it up a bit while I have access to everything. I can model the movement to see if I can give it a bit more clearance. The intention is to have the spline end mounted from the diff side rather than towards the hub. Cheers Tim
  6. I have been considering a replacement for my very sketchy Rotoflex discs. Having just shortened a drive shaft to accommodate an overdrive I was struck by the fact the flanges are shared between the axles and propshaft. Taking this further, rather than going the Steve Smith route with Datsun 240Z axles shortened and flanges adapted, why not shorten a driveshaft to about 15", cut off the rotoflex fingers from the stub axle and weld a flange on it. There is plenty of travel on the spline, more than is required, the incline angles aren't that bad to begin with even at full suspension travel. Any drawbacks I'm not seeing? I've added a pic of the Datsun axle for posterity, it still needs to be shortened. Cheers Tim

    Enlarging a hole

    You got away with it with existing in hand tooling, resourcefulness in the right application for the moment . Sometimes you just have to make do with what you have. A drill can be ground flat bottom like an endmill and can be used carefully to "move" an existing hole going to a larger diameter, carefully being key. Cheers Tim
  8. That's right Nick, about 220 Km away, @ 120KPH on the 401 highway. Toronto is an okay place to visit, nearly the most expensive housing in North America as a drawback. But only 180 Kms away from the Muskoka Lakes , great twisting roadways up there, watch out for moose though. Pretty exciting to have a member and his car move over here, I'm putting together a spit six for my wife, would be interesting to see Nigels version.
  9. Where abouts in Canada are you landing? If you need anything please let me know, if I can help you out with anything from this end just ask. Cheers Tim

    My weekend so far

    That Jag rekindles my lust for a series one. Helping out a new triumph convert with some NOS body parts I had surplus, I delivered the parts to his parents farm. His dad met me and we conversed at length about cars and the hobby and his son's enthusiasm for his spitfire. he mentioned he had an E-type and was looking to finish it someday. After some more conversation he invited me to have a look, it was actually in his barn. We went out, it was a large old wood barn, multiple level, and sure enough there was a work shop and loads of farm equipment, and some vehicles, and a distinctive shape under a canvas tarp. A red 1964 E coupe. Pretty good shape an older restoration that had been partly disassembled, complete with drivetrain though a 4.2 engine installed. It was beautiful, a paint job and interior refurbishment away from the road. He had it for 35 years, in his seventies now, still optimistic he will get it done or at least his son will inherit it and finish. Ill be doing my best to stay in touch, one never knows.

    Nick & Chris's Gt6 Mk 3

    Outstanding, you are inspiring me to get creative and tackle a few projects in the same manner. Cheers Tim
  12. John, That is a flux capacitor, I would be wary of going 88MPH, you'll never know when you'll end up. A bearing puller I made to remove the bearings from GT6 transmissions Not a tool especially but using tools in a way they were not meant to be used. A lathe steady mounted on a milling machine bed, holding the ram of a 7" X 6 foot long hydraulic cylinder, the eye end in a rotary table chuck, milling a bevel all around the welded cap to separate it from the cylinder, by hand feed with a wrench on the jaws of the chuck. It was slow but successful, saved my customer $8,500 for a new one. Cheers Tim

    Refurbishing Lucas Injectors

    Thanks Nick, is it okay to ease them back in with a spot of vasoline (petroleum jelly)? Awesome hand forming on the metal for the GT6 project, I seem to recall you came across some hand rollers and shapers and such , you are putting them to good use. Cheers Tim
  14. Has anyone had the Lucas PI Injectors apart and replaced the Viton o rings? I have a set that were from Steve Attenboroughs GT6, GT overlooked redoing them when he did the pump and metering unit some time back. Shipping them back to the UK for refurbishment is not practical cost wise plus there are 2 that are the threaded in types and 4 push types, likely not a good idea trying to avoid core charges with mismatched items. I have them apart, is it okay to just replace the o rings leaving the spring settings alone? Cheers Tim
  15. I have received one of my Lucas PI systems, sent fully refurbished. Some serious delays but the items look new, I thought the fuel pump was a reproduction it looked so good. So on to installing and learning a new process. While there is another setup, minus a few injectors and maybe a PRV, left with the rebuilder I wont be pursuing a rebuild on it. I had thought of using the manifold to go EFI but it seems a shame to break up a system that someone else may need for a restoration. It appears to be a CR from a 2.5 Saloon. I am leaving it with the rebuilder to market it where he sees fit. Cheers Tim
