New 3 Lane Routed


32coupe

Recommended Posts

Hi all

Well the bug has bitten and now I need a routed track in the shed, so I went on the scrounge for building materials and made a start.

I was going to build my table frame from timber, but a good mate donated some steel, and I like working with steel.

I have enough room for a 4.8m x 1.8m track, and I had a design worked out , so this is the frame I made with a few bits of scrap RHS.

I know a kitchen mob that have heaps of left over packing sheets, so I grabbed my trailer and went to see what they had, Luck would have it they had a stack of 1.8 x 2.4 sheets, 2 would do my whole track. Not ever having used a router before, I just went for it, I think I did OK. The best thing so far is it owes me $0.00, but that won't last much longer.

Well another weekends worth of work has gone into it.

 

I routed out the braid groove and painted the lane colours.

Then laid down some ferradore, it only took about one litre, but it only comes in 4litre tins.

So all I need now is some Magnabraide, come on Steve when are you getting me some?

Looks good, you should be able to do some fast lap times when you learn how to drive properly. :D

 

Does Deb know about your Twin Peaks fetish?

 

Hey, she bought them for my birthday.

If you intend to lift it via pulleys I would recommend using he marine grade pulleys and nylon rope cable - they are weight rated and not as expensive as you may imagine . I used 5mm yachting rope to hoist my oval track , all the details and a link to Binks yachts are on the ( oval track dos and donts thread . ) putting on the pulleys etc starts around page 11

http://binksonline.c...ngle-lead-rf919 Binks yachts are in SAust but these puleys etc are available from any good boating supplier

 

Bunnings has pulleys etc which are ok for a cane blind but when your parking a car or standing under the track its nice to know the gear holding it up is actually rated to carry the weight

Thanks for that, I did intend on using quality pulleys and cable and having the table held in place when up by steel locking tabs that will hold the full weight of the table, not the cables and pulleys.

As you say, I want to be able to walk under it without the fear of it landing on my head.

The pulleys I used were very high strength - excellent value for stainless steel fittings . Dont use steel cable on the nylon rollers go with the Dynex rope its called Dynex 75

 

Rope - http://binksmarine.c...-75-3mm-hrl-130

 

5mm dynex rope ( breaking load 3200kg ) $5.31 per metre I used this as the main load carrier

3mm dynex rope ( braking load 1500kg ) $ 2.61 per metre I used this one from the corners through to a system of steel galvanised plates to equal / balance the lifting points out the 5mm rope ran from the balance plates to the winch

 

Electric 12v winch was a lightweight 4wd unit meant for those light 4wd ag bikes ( big balloon tyres on them ) it was under $200.00 it can hoist 2000kg

 

 

Pulley blocks - RF419 or RF417

http://binksmarine.c...=com_virtuemart

 

double pulley is the RF417 single pulley is RF419 Double pulley is $18.00 single pulley is $9.90

 

I cant see the single pulley ( RF419 ) listed on the site but they do still make them . The safe working load on the RF419 was 600kg with 900kg braking load

 

Lead blocks - RF919 $13.25 each ( working load 600kg breaking load 1200kg )

 

as a comparison the bunnings el cheapo pulleys with NO load specs on them were about the same cost - maybe 2 bucks cheaper but as they have no load specs I wouldnt trust them to lift a bucket of water .

 

On the single pulleys ( where the rope changes direction ) I used two high tensile bolts to secure them in place , one bolt went through the centre of the pulley itself which to me made it even stronger .

This is what I meant by steel galvanised balance plates , the cables from the sides of the track go up to the top pulley blocks then change direction through another double bolted pulley then on to this arrangement below - this set up allows the cables to balance the weight side to side . On the track I used large eye bolts so there was some threaded adjustment to set the cable tension .

3mm dynex lead ropes carry the weight from the sides then 5mm dynex rope at the left of the photo carries the main load . The centre shankle ( u bolt ) has another 5 mm dynex rope that trails back to the other end of the track and conected to the other lifting balance plates . It looks complicated but really all it does is balance out the load better instead of messing around to adjust the eyebolts at the track and it self adjusts for any initial stretch in the rope

 

The stainless steel u bolts / shackles had wire through the threaded pins so they cant undo

 

8mm Shackles were about $7.00 each from memory rated at 2000kg

6mm shackles were about $5.00 each rated at 1500kg

Where the cables all meet just before the winch I used this arrangement so the cables could align easier with the winch and the point they were pulling from

 

The eyebolt with the blue rope on it is a safety thing - it was lowered after this photo to allow the 5mm rope to run through it , so if ever a pulley wore out and let go there was the eyebolt there to catch it all . I also doubled up and used two 5mm ropes ( just in case one got an unseen cut in it ) to do the main load lifting

my oval track ended up around 350 - 400 kg

 

The set up I used in the end could probably lift a small Korean car or two but a bit of over kill is better than lying flat on the deck with a track on ya belly huh

Much easier to rent these guys.

Only hiccup is you can't walk underneath when the track is up.

 

And it has to be a small track, HR rules have a max load limit of 10 kg per person.

May the downforce be with you.

Hi Steve

Braid is down and all 3 lanes are fully functional, you are more than welcome to drop in any time and help me rubber up the surface.

Supercheap had a sale this weekend, and I got an electric boat winch cheap, so that is what I'll be using to lift the track.

But I'm having too much fun using the track to even contemplate how and where to mount the lifting gear just yet.
