Wood5tock's Boomerang Resto

[WillyChang]

Ah the adjustable motor plates that Willy Chang was talking about

He's right this is genius Although the screw head is rounded to b*****y

Pinion shows no wear but also no, or very little, signs of lube

r-ohoh!..shouldn't be a 2nd screw on motor, should be a round shaft with double threaded ends;

big plastic washer keeps plates in-situ then a 3mm flanged nut bites into washer.

Shaft wasn't easy to find pre-rere; using a threaded screw/rod isn't a tight fit against the plates.

i'd change the other screw into a hi-tensile caphead too

and that pinion is toast, toss it

good new pinion will have flat plateaus on the teeth tips, yours is all 90% sharp already

[WillyChang]

Curses a crack! Oh well only one found so far

put the screwpin back in but don't tighten totally, drip superglue into the crack

that should hold fine until you have a huge smack (which will break a new arm also anyways)

[WillyChang]

Well it's definitely a vintage 'Boomer' there be a 'C-Clip' which 10 secs later was fired across the table to be lost forever

"Wrong " , That was only the Bigwig that had that .

The boomerang had the two screws with one that had the plastic washer .

BUT , nothing to say thats not a good idea & this is why it came on the bigwig !.

But the boomerang did have the two screws ..

[WillyChang]

heck, u be right for old & re-re Boomerang

Super Sabre definitely has the Bigwig stick & flangenut though.

Oh !! ok that is some thing i DIDN'T no about the super sabre .

Will have too take note on that , Thanks Willy .

[WillyChang]

ya Sabre has it. Built 1 new in 1987 & recently rebuilt 1 wreck... guess that confirms its a real Sabre too

haha we've got 1 used old Boomerang too, it got cleaned & tidied up yrs ago on arrival.

Always thought OO had lost the special motor rod and replaced with screw,

never thought about x-checking the manual until you mentioned it today.

Well is seems that luck is on my side regarding the 'flying C-Clip' Once I had cleared the bags of components away for the last photo there it was! Right in the middle of my mat! How it got there I shall never know but I'm glad it did

Thanks for all the info guys especially Willy. It's those little nuggets of experience that makes the difference will be updating tomorrow with the second Boomer

[wood5tock]

Right as promised time to do exactly the same the my other Boomer. I will let the pictures do most of the talking as it's the same exercise so no need to have a Deja Vu induced coma

Ironically even though the exterior parts are a little rougher than the white one the internals and tub are lovely

Undersides of the front arms have seen better days

Some odd screws here and there

These parts are in better condition than the first one

Whoo hoo a genuin steering pin... Sweet!

First crack so far

A lot better than the other ones but still a little worn, at least there was plenty of grease around and not dirty grease holding dirt and harmful grit either

Some heavy wear here

Plastic bushing all round

No saving these then

And these have taken a bit of punishment

And as for these...

A bit squiffy

Somebody decided to shoe horn an 'E-Clip' in a vintage box, no adverse wear or strain by the looks of it, but will check better once I have started to inspect the parts in more detail

Clean grease but the wrong type, looks/smells like mineral auto grease

Mmm... Nice! this stuff stinks like automotive gear oil

Only one 'O-Ring' used in these dampers

More lovely smelling oil...

Well that's the second Boomer 'bagged and tagged' ready for inspection

[THE HP FREAK]

HI!... If you want to keep the front/rear upper/lower control arms from splitting where the pin goes in, heat the pin up where the threads are with a lighter before screwing it in to new arms. This lets the screw melt into the plastic instead of forcing it's way in and spitting it. I've been doing this for years and have not had one split on me since.

[matman]

That's NOT a vintage gear box with the E-clip . Look at them both & you will see they are different .

This one has a mix of new & old .

[THE HP FREAK]

HI!... You can use the "E" clip on the vintage gearboxes. I do it all the time. I hate those "C" clips. lol.

[matman]

HI!... You can use the "E" clip on the vintage gearboxes. I do it all the time. I hate those "C" clips. lol.

Well NO you can't ! . As it binds up the gear box , as the RE re gear box's have been changed to suit .

Why do i have too say this over & over again ?. .

Look at the pic's of the inside of the front gear box & you will see the E-clip flush with the gear box &

the C-clip is flush with the gear box on the other half .

[THE HP FREAK]

HI!... Never had binding in mine. You just have to run super thin "E" clips that I get from a local fastener supplier. Never had a issue on any of the Bigwigs I have built.

NOW ! that you have made it clear of what you had done , that makes sense & hope it won't

confuse anyone . with the E-clip issue ... Only because of clearance etc of gears etc .

Not a bad idea you have .

But then again ! can we class it as vintage .....

[wood5tock]

I knew about the 'C-Clips' used on vintage models and the 'E-Clips' used on modern and Re-res and not to mix the two due to the binding issues and the fact the gearbox casings are designed for each accordingly.

My question is this how can I tell the difference between vintage gear cases and Re-re?

The only reason I question the point you made regarding the two halves of the cases being a mis-match of old and new is that when I had a look at the side that had the 'E-Clip' on there was no tolerance left and no end float whatsoever. It just felt that the 'E-Clip' was creating a bit of stress. i also noticed witness marks on the gears though the gears where never hard to turn when the case was fully assembled.

[matman]

Well if you look it also does NOT have a ball bearing & it should have on the re re . This is why

if feels tight , as the re re didn't have plastic bearing , with steal washer .

If you also look at the front where the bumper block goes , you will see that the re re is

filled in & the vintage is NOT . + like i said the E-clip pic you can see it is recessed in & level

with the gear box . so the bearing sits lower .

[matman]

So how is the build going wood5tock ? . You waiting on parts ? & what have you found so far . Parts wise , vintage vs re re on your

boomerangs .

Great thread so far .

love the marigolds wood5tock .

Awesome to see these teardowns and work starting. Thanks for sharing! Can't wait to see the end result.

Let me know if you are after some of those c clips, Woodstock.

I have a hundred or two of those and more than happy to pop some in an envelope

and post to you so you can flick a few across the room to your hearts content

Right here we go with an update, I was very diligent and inspected every part for both Boomerangs and made a list of all the parts that need replacing. I then wrote all of these out including pat numbers, suppliers and prices etc. Feeling very proud of myself I went off to bed and left my notebook with said master list on the side by my chair and went off to bed. The next morning after a little lay in I decided to get my notebook and start the ordering...

Too late one of my Jack Russells decide he would also add his own stamp on things by not only half eating the list but all my other notes to do with my projects...

After re doing the lists etc I realised he had done me a favour as I had gone a little overboard with the new parts, in fact it came to a similar amount as a NIB Re-Re Boomerang and a nice few accessories (if they were still made)

I decided to go back through all the parts and re-decide what the project really needs in the way of new parts. With the new list complete it was time to clean all the parts...

Just for Sidewaysdave69 NEW Marigolds, well the mint green once were clashing with my all blue set-up

I decided to use my stronger APCs from my car detailing box as I have had good results with this stuff, it also smells of oranges and lemons

I left the first lot of parts bathing for a little while before a good scrubbing

Agitating periodically and re squirting

First set of parts done, rinsed dried and back in there bags, on to the next batch

All the parts saved have now been cleaned and back in there bags ready for the re-build. I have also placed more sensible orders for new parts today as well.

I have decided to create the self queen first so i think I shall create two new threads as the two car will now branch off and it will be a lot less confusing, at least for me anyway

This is giving me ideas for my baja champ! Are you going to be reusing the msc or will you be swapping to an esc? I'm in two minds with mine, keep or swap?

I'm going to keep the MSC for the shelfer but use a ESC in the runner. Luckily both MSCs are in great nick so I can rake my pick
