Hey,

I am trying to make a boomerang

coaster like "Mind Eraser" at SFWOA (I think it's there).

But I need a bit of help making the lift hill, are there any tutorials on how to do one

for a reverse incline launch or whatever it's called?

I'll post a

photo later, because I need help with it...

I just made a backwards lift this weekend following

tips from this site.
Its actually pretty easy, you just take a dark-grey connector

and put in in a chain lift piece, facing the right direction, it would grab the end of the

train and pull it up, and release it when the connector goes over the top gear.

OK. Now I have finished the coaster - but with no lift

hill - I'll try that tommorow. But I have a 6 ft drop, then a ~1.5 ft cobra roll - but

it doesn't make it on the way back . What should I do to fix

that? (pics soon)

Add a lift to the other side, so that it will make it back.

Dejavu has lifts on each side, so it would not look that bad, and that is what I did with

my boomerang coaster!

Don't all boomerang coasters have two lifts?

Sea Serpent at Morey's Piers in Wildwood, NJ has two.

Ya they have one long one for the first drop and a

short one for the second one because it still has some speed go to partly up the incline.

How can you make the second lift if the chain dog won't let go the opposite

direction. It will keep trying to get up the lift hill even when it's at the top.

[james_isaac]

OK thanks. I'll do 2 lift hills then


ThEoNe: I'll just tape down the "chain dog", and put a rod in the

chain instead?

[james_isaac]

Actually yeah - if I did that - it would hardly ever be

the right time to catch it.

How did you do the second lift hill?

[coasterfreak11]

You have to make the lift right after the loop, so that

part of the train will be on part of the loop so that the train will be partially over the lift

and the train would be stopped ( you may have to use like a 5-6 car train) and then it

will catch on everytime then. Hope ya understand!

[james_isaac]

Oh I see.

But I might have to cancel the

loop, because I only have 1 set, and I don't think i have enough pieces



I'll do a

bunny hop instead.

^ Yeaah, i did a loop, and it didnt make it back...
