I have set about designing and making a gearbox to correct the speedo in the Land Rover. The speedo currently reads about 5/8th the speed which it should, this is due to having the LT77 5 speed box rather than a series box. So I need to increase the speed by about 1.6 times. I have chosen some brass gears off ebay, I have a 45 and a 30, which gives me 1.5, so that speedo reads slighly lower than my real speed similar to what car manufactures do. I have put a 28 tooth gear between the two gears to make the output turn in the same direction as the input. I set about getting Ben’s 3D printer out and trying to get it print well, but it was taking ages, this was my best result, which was about 96% the size it needed to be. As you can […]
Okay cabin air a little posh, I’m on about the air intake for the hot/cold air into the land rover for the comfort of the passengers etc. This intake is the side of the wing, and it’s the same wing I dented a number of weeks back and also broke this plastic part. I contemplated just ignoring it and living with it broken, but then I fixed the 3D printer. Then I modelled this, but minus the text as per the below pictures. I had a conversation with my dad and he suggested I didn’t need to duplicate what was there originally, so I hit on this: I set it printed last night, but it didn’t come out well, so here goes again:
Today I printed out an updated design of the air duct adaptor that I have for the drivers side of the land rover. The completed part needs fitting to the dash of the land rover somehow in a manner that allows for the removal of the lower dash but yet allows for the air to blow were it needs to.
Having borrowed the 3D printer, I used it to print out a cup holder for a Fiat Spider 124: This next video was taken at too low a frame rate, about 1 frame ever 15 seconds; This was a successful build: The finished product: Needless to say the print didn’t come out perfectly scaled… so the bit that is meant to snap into the car was too small and didn’t work.
