Its a R34 Skyline dash, its all on the page before, 2nd last post.
I havent tackled the drivers side of the dash yet, have to get rid of a POS on my driveway so i can turn the zed around.
Ill give my trimming skills a chance at the top half of the dash, but that may end up getting done by a pro. We'll see how it comes out.

So I was inspired by the 'what have you done to your car today' thread.
I haven't actually done anything to my car worthy of posting, but I have been busy with another toy I've wanted for a very long time.

I picked up a 2 post Tecalemit hoist from a friend, it had been sitting in his paddock for a while.
I made a slow drive home with a very overloaded trailer, but we made it all in one piece.
(yes, I used an engine crane to lift it all on and off the trailer, lol)

It looks pretty rough, but its not too bad. I needed to strip a lot of it down to clean it up, but mainly to make it a manageable weight for me to move around on my own.

I worked out where it was going to sit, then made some base extensions to make it a bit more stable as I wasn't 100% sure about the concrete it was going to be bolted down to. the last thing i want is the hoist tipping over while something is on it (not that I ever plan on lifting up any big 4wd's)

Once that was sorted I moved the arms off to the side to start getting painted and I lifted one of the posts up into position.
I had worked out that it would be easier to do it this way, manually winding the lift carriage up and down between power washing and re-greasing and re-painting.
It also gave me a chance to check the clearance on the screw and make sure its still within spec.
Turns out it has almost no wear on it at all, so its either been refurbished at some point in its life, or its not that old to start with.
Either way, win for me.

From here it was a lot of cleaning, painting, greasing and heavy lifting as I assembled both posts, attached the arms and drive chain.
It was originally a 3 phase motor and contactor switch, so im in the process of sourcing 240v gear for it.
But its assembled and looks good!!

So, after thoughts...
I have wanted a hoist for many years. You can buy them new for around $1500 or second hand for anywhere from $500 upwards.
Screw type hoists are a lot safer than hydraulic because the screw also acts as a safety system, whereas hydraulic use a locking pin arrangement, however screw type hoists need a high torque motor to make them move. This one has a 4kw motor on it.
3 Phase hydraulic hoists are a lot cheaper and easier to convert to 240v and keep the circuit load under 15A
Its arguable that hydraulic type hoists are less suitable for outside environments due to UV damage to hydraulic lines, oil reservoir ect ect, but any equipment outside is going to require a lot more maintenance anyway.
My options were to either keep it 3 phase and set up a phase changer ($6k), get 3 phase connected to the house, or convert to 240v.
I got a phone quote of $20,000 to connect to the 3 phase service on the pole behind my garage and was told that I would then be charged a commercial rate for my home power where I would be charged for 3 phase power even if it wasn't being used. This could also risk the council asking why a residential premises is being charged a commercial rate and come investigating, no thanks, lol.
Converting to 240v means a new motor $400 approx + new switch contactor $200 and new 32A circuit to the garage $1500
My slab is 100mm thick but I don't know if its rebar reinforced. To get a slab poured is around $2-3k
Ideally id have a hydraulic type hoist on 240v inside my garage, but my roof height is too low.
Hoists are a lot more expensive than you would have initially thought, but I can tell you now I'll be smiling every time because im getting too old to be crawling around on the ground.

Next post, car stuff, I promise...

Awesome, very jealous.

Just a thought with your 100mm slab, if rock is close to the surface (like my place) you could anchor directly into rock using galvanised bars and grout.

Shoot me a pm if it sounds like something you're interested in.

Cheers

nothing but dirt under my slab. my house is built on what used to be a flat plain used for farmland.
I am using concrete screws instead of dynabolts, Apparently they are better suited to old concrete (Especially near edges) because they dont have a tendency to split the concrete apart.

Yep Ankascrews and chemical anchors are generally a better option than expansion (mechanical) anchors for edge distance limitations as well as mass/unreinforced concrete

PM sent RE slab.  I typically design 100mm slabs for dealership services areas unless ground conditions are poor or they have a specific jack generating a point load.

Cheers Neuby,

Ive added your PM here because its real good information that im sure someone will find handy later.
 

Hey mate,

 

I thought I'd add my 2 cents about your slab.  After all I'm RPEQ structural engineer, might as well help out if I can!

 

If your using it regularly ie. something on the hoist more than 6 hours a day.  It would pay to check the edge.  If the slab is 100mm thick throughout it would pay to move the hoist away from the edge of the concrete if possible.  500mm to centre of the post is ideal for a 100mm slab.  One way to check is to dig down the side or drill through to check if an edge thickening has been installed.

 

Chemical anchors are preferred for durability.  Being out in the weather subject to greater variances in temperature, the differential volume changes will be greater between metal and concrete.  Mechanical anchors relying on friction can loose capacity.

 

Another option we add up in this situation is cutting squared of concrete out and installing bored piers under the posts.  This is heaps cheaper than a slab and can be done by anyone.  

 

Hope that helps.

 

Without going and measuring it for accuracy, the edge of the hoist is around 300mm away from the edge of the slab, From what I remember in the installation manual thats about the minimum distance they reccomend from the edge, using dyna bolts.
Concrete screws should be fine with that.
I'll probably only realistically use the hoist 20 times a year max, more likely to be less than 6 times a year, so I should be right, but it'll be something i'll be keeping an eye on for many years to come.

Hi

 

There is some good advice given already.

The only thing I would add is, if you were to cut / dig and put piers in, I would set some HT theaded rod into the piers rather than installing anchors after the the fact.

 

Cheers

Hi Nizm0zed,

 

Been reading your build thread recently and you do some incredible work. Couldn't help but notice that this looks like the original air intake manifold you made for your L28 Turbo engine (not sure if its the same one or not):

Keep it up!

 

Cheers,
Adam
