    Thank you Angrybear, I couldn't find the pics link in this BBS thread so I went for your image host option. I have got a Photobucket account, but it's 'off the chart' hopless and slow!!

    Here are some pics so far of stuff to show.

    The grey and alloy pulley parts are home made and home cast then turned. The pic shows one set running off the Vauxhall windscreen motor gearbox. The gearbox is very slow, but after playing with different size pulleys, I got the cord speed pretty good and quick The alloy boss was turned up and a 10.5 degree taper hole made so the output shaft taper splines can engage.

    The extra pulley bolted to the bottom of the proprietary Crapbay pulley was turned up from some nylon stock I had. There was a lip in the proprietary Crapbay pulley, so I used that as a register for locating my nylon extra pulley. The resin double pulley is yet to have a pair of double bearings added (they are on their way) I just drilled a 10mm hole for now so can test the speed. The picture also shows some swarf in the 'U', that is just some muck off the bench, the 'U' IS perfectly smooth

    Now I've got the speed right I was able to order the drive belts. They are 175mm diameter and 5.5mm round cross section. Hoping they will get here tomorrow so I can make the whizzer boxes and get all the 'guts' in one working place

    Quick update on the whizzers.

    Starting to stich all the bought and made parts together now

    Total cost of what you see here is £36! Basically just the motors, the rest is made from stock I already had.

    Looks nice.

    I wonder what 50m of that ducting would cost

    Just need to make the covers now.

    Looking good, Rob.

    Do you think the motors would have enough torque to work a target out to 50 yards ?

    Something I'm hoping to built at Quigley Hollow when I'm back on my feet.




    All the best Mick

    Hi Mick,

    Torque is not a problem, drive belt slip and gearing up are problems I've had.
    Gearing up is easy, but belt slippage is more of an issue.
    For now, I've solved it, but the belts are a little stretchy and they may slacken off over time?
    If you made the gears out of push bike sprockets from the front and back,you'd have it cracked !!
    Somthing I may end up doing, but for now, it's all working fine

    Replacing the pulleys for bike sprockets is very easy, just turn the pulleys down 3mm and bolt on the sprockets.
    You can buy whole new matching bike sprockets (cassettes) and chain from Crapbay for peanuts!

    Belt slippage, try using bigger pulleys.

    And the cover boxes made and painted for the whizzers.
    Note also the guides infrount of the cable wheel.
    The guides are 7mm with a smooth 'funnel' just incase the cable gets a 'wobble on' at any point.

    And some more progress today between working!
    Needs another 2 tonne of chippings really, but it will do for now. It has a thick DPM layer under it, so it'll be fine for a while.
    I'll leave it a few more days so the concrete can set a bit more around the posts, and then the range can go on top.
    Then I'll make the felt roof and insulation to cover the range.
