    I have been making good progress this week :thumbup: I made a couple of different length arms for the tower select.

    Remade the reverse clamp so that it is now the same shape as the rest of the block, I also decided that the cable will start at this end so made space for that and then countersunk the bolt that holds the reverse rod in place.

    I then set to work on CAD and decided to do a little CNC milling to give the product some identity.

    And i fired up the 3D printer, here it is making a very light weight lattice core part for the project.

    :p

    I have been working hard on this but have little to show from it, I have had to wait for materials and tools to arrive to allow me to make certain parts.

    Anyway, the gear knob finished on the 3D printer and i also made wooden one that im going to use. The 3D printed version has now been cut in half for an examination, the lattice is very strong and light.

    It has a textured surfice finish that can easily be sanded down - ignor the dirty mark i created around the rim.

    I then modified the original relay lever and also cut of the lever from the relay shaft and poped it on the lathe to smooth out. I made the new bearing for the relay shaft in two parts as it was much simplier, none of my drill bits where long enough.

    It's a techies wet dream is that....I'm just glad that I no longer have to fix printers :lol:

    It was just for you mat :hug:

    I have been wondering what i could do with the printer for a while, the gear knob seemed like a good idea. I have something else in mind i will make in the future with it.

    I have worked on the base plate for shifter to sit on, it will also incorporate part of the mechansim as seen in my earlier sketches. I started of making a full scale mock up in wood that I tested for fit in the car.

    [​IMG]

    I decided to change the angle of the folds and increase the length to give more support to the structure. Again this was cut out of wood and tested in the car, the side of the base plate was cut to allow the mechinsism to poke through.

    [​IMG]

    I then sketched a final version of this and laser cut a template out of MDF that i used to mark up my aliminium sheet, unfortunatly the laser cutter does not cut metals.

    [​IMG]

    I cut the sheet metal out using a band saw and a jig saw for the inner parts, all finished by hand and the inside wet'n'dry' sanded to 1000 grit.

    [​IMG]

    Then i folded it into shape today, im going to maybe add some more structure to this and get some sheet welded in at the ends. It will bolt to the sides of the tunnel when positioned.

    I drove a Mercedes 190 Cosworth in early nineties with dogleg 1st. It seemed to make for faster 2nd to 3rd gear shifts when driving A roads that's for sure :-)

    If you'd like to whip one of these up for the Stroke Charity Rally Caddy, I'd be sure to big it up at every show I attend with the vehicle on display :-)

    Cheers guys, im working hard on this as I want it to work well and look good too, its also a nice way for me to practice on machinery I have only used a few times. I dont think I will be selling any of these soon, they are a little involved in their manufacture, it would be nice to pack up work and make things like this all day... best get my lottery ticket bought.

    I have put it all together for the first time, the base plate still has the protective wrapping on one side and needs de-burring and sanding on the out side, there are a couple of bushes left to make and fit, therefore it looks a little rough around the edges. The pics are quite grainy as i bumped up the ISO, i quite like the warm feeling this creates but will get some proper pics taken once this is finally finished.

    I hope you enjoyed the thread and i will let you know how i get on fitting it to the car and testing it in the future but have a feeling this could take some time. Cheers Tom.

    It's just awesome, if I was as talented at making things as you I'd be one happy person. Top work :thumbup:
