Picked up a press brake the other day. Have spent the morning freeing it up. It's mostly complete apart from the linkages between the kick lever and press, and return springs.

Any ideas? 

From playing around with some lengths of steel I have, I feel the plate with the 3 holes should have a slotted vertical upright, and the middle tab is what joins to the press to provide clamping force (because bigger arc). The further most tab is probably where the springs attach and join the small tabs on the base part of the brake.

The two flat bars where the kick pivot is mounted has me confused though as I can't figure out the top holes purpose. Possibly it has none and was just an available piece ?

Does anyone have plans for a home built car rotisserie please?

I have one of these

Its a little more basic than the sold ones.

Two hoops with a 2m ID

And they sit on a large piece of C channel and roll on some boat trailer rollers.

Weld some mounting tabs around the inside edge and you can make jigs to hold onto anything. Good for attaching to say suspension mounting points rather than rusted out bumper mounts. 

Im working on a foot brake ATM. Maybe just an additional braked caster wheel to run against the outside of the hoop.

 

I'll probably be done in about 6 months if you want to borrow

Great benefit of this type is you can just hang it against a wall. The double engine stand type take up quite a bit of room.

 

You can also get some steel rims and weld some J shaped steel arms on them and just push the car in its side of you have the option To leave the suspension In

We were out in the Holden on Saturday, got about 5km away from home and heard a weird noise, sounded a bit like a speedo cable tick from inside the car.

Stopped and had a look under the hood, then decided to drive home stat.

Idles OK and just driveable but much more than light throttle results in misfiring.

Any guesses on what's wrong, place bets now :0

Going to start investigating now.

The thickest I have cut is 300mm, hardest part is blowing through for the start, I had to drill a couple of holes to start from for the internal holes
