Do you have any pics of how you hung the block and tackle....

I trying to figure out if my roof will support it

i am building a wall mounted crane at the moment (literally, im just taking a lunch break from welding bits), it will be bolted to the frame of the garage using a piece of 100x50x7 rhs and 12 1/2 hi tensile bolts through the steel uprights. it will swing 180* with an extendable boom to reach the middle of the garage, and a block and tackle on the end..

i will post up some pics when it starts to come together a bit more... the good thing about it unlike a straight block and tackle is it can be moved around to clear the car etc..

sounds like a great idea...I wouldn't have the room in mine though...might just buy an engine crane lol..but even then room is minimal :(

hence my thinking about a block and tackle...but sloped garage entry will make it hard to push 1400 odd kgs back into the garage after i move the car away from the hung donk =\

cool, are they just normal pine truss' though?

If you have a pine truss roof, hang the block and tackle over the top of the truss at a point where 2 diagonals meet. This way the timber will be in compression, the gangnails don't see too much load, and there's very little bendng load on any timber members. Much stronger than hanging weight off the bottom beam in a truss, but still not bullet proof.

I've used this setup to remove L4's out of a number of Dattos. Don't currently have a hoist in my shed, but haven't pulled an engine for several years.

My shed's too messy atm to post any photos (halfway through a couple of projects as well as having a rally car, trailer, 2 cars and about 6 bicycles in there). When I tidy it up a bit I might post some pics.

heres a few pics of the crane that i just made... its not quite finished yet.. but you get the idea..

the wall that it will sit against

the post that it will mount to

the sketch

and the main part of it.. i still need to get some rhs for the extendable part and weld the hook on the end.

and the hinge set up... just some tube and some big bolts.. just drops in.. each bolt is capable of 2t.

you have to remember that this crane is purely for removing and swinging a 200kg engine out of way.. 5 min use to lift it up and swing it over.. and 5 min to swing it back and lower it down.. so its probably over built for what i need... we thought about bearings and slides and all sorts of stuff... but really.. its just more hassle.. if i was using the crane every single day then it would be a different story.

yeh it is... thats what im worried about aswell... the part that mounts to the posts is like 7mm thick... with 12 1/2 bolts so im hoping that will spread the load out and it wont be too much of a drama... we'll only be in this house for another year or so.. so its not worth me doing too much work to the actual structure of the garage.. the crane can be simply unbolted and take it with me.. so the crane is built to last.. the garage is not.

It's more the bending moment at the base of your crane.

By using multiple mounts you reduce it some what but ultimately when you lift something up at the other end (say a 200kg rb on a 2m lever arm) it'll try and bend the post outward. It'll probably hold 200kg vertically fine but once it starts to bend it can go pear shaped fairly quickly.

it gets worse when you rotate the crane as you no longer have the 2 posts in plane, but side by side and that significantly reduces the moment it could handle.

If you want to continue with it i would be doing some trial runs at full weight while keeping a good eye on what the poles are doing.

It's more the bending moment at the base of your crane.

(say a 200kg rb on a 2m lever arm)

actually it doesnt have to lift 200kg... more like 130kg.. :rofl: and it should only be once while im at this house.. next house will have a much better setup.

i will most definatly be trialling it with weight before i go hovering an engine over the car.. worst case scenario... i make a new 100x100x7 post and dynabolt it to the floor and to the original post.. that isnt a drama.. when the crane isnt in use, it will be secured at the other end... but thank you for your advice.. it isnt the best situation i know, im doing the best with what ive got (so far the crane has cost me $0) and the height of the garage is not suitable for an i-beam with a running block and tackle..

I'm way too embarrassed to show any pics of my garage and shed at the moment. Only moved in 4 months ago.

I have a double car garage which is roughly 6 x 6 mtrs in size with concrete floor and double sized roller door. It houses the wife's car and car trailer with race car on top.

After these two items are in the garage, there is hardly any room for anything. Just some book cases for storage down the sides.

I have a tin shed further around the back which is a decent size roughly 4 x 3 mtrs which is yet to be converted to the "workshop". I plan on putting 240v power to it, install power points, fluro lights, benches and shelves.

Badhairdave mentioned some excellent points about lighting and benches.

This thread will be excellent to get some ideas from to set up my shed properly!

One word for you Duncan....

ebay

Should be able to flog off any old tyres you don't want real quick and make some room. Plus, you GTR deserves a garage at night!

Actually i buy most of those 2nd hand and they are keepers! At $710ea for the Michelin slicks (new) it would be far too taxing on the budget. So all of these are keepers. Once i am finished with them they are well trashed. A tyre rack sounds like a good idea!

    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
