how to tell a cro mo frame, heavy tools

(1/4) > >>

mattuk:
right bit of a dilema

i have 2 frames... both identical in every way visually

i believe them to either be a screamer or a freestyle by the mid 90's company HEAVY TOOLS who were by KHE

from very little info available throughout the internet ive managed to find out that the screamer was full 4130 cro mo and the freestyle was steel

so i have for definate one of the following combinations

screamer/screamer
screamer/freestyle
freestyle/freestyle

but which one........ 

ive looked under the BB and both have reference HT BO

one has        HT BO 3  folled by serial number beneath
other has     HT BO 2 also folled by serial number beneath

now i also have the other frame heavy tools did but i know this is a heavy tools "ruler" as its they only did 3 bikes and its the only one that didnt come with a platform

this has code    HT BO 1  folloew by a serial number beneath


so to me this tells me that   good chance i have one of each

so unless someone out there has a heavy tools and can check their codes for me im totally screwed in knowing whats what

anything i can do to check if its cromo or steel

magnet?  tapping to identify sound?      you see they both still might be the same model so both might be the same but i dont know whether thats a screamer or freestyle

really annoying so someone please help lol     

thanks in advance  :D

gary4130:
the screamer had ad lugs on +freestyle didn't if i remember

mattuk:
is that definate?      100% certain regarding the lugs?

theres a picture of a freestyle on here that someone had and that had ad lugs....    but may have been a screamer that someone stickered up wrong i guess

i am amazed at how little information is available on these bikes     mid nineties they were quite popular, they were affordable quality bmx's    dont know where they all vanished too    :(

half way down this thread there is a freestyle pic and it HAS ad lugs???

motomagII:
wouldnt the steel non chromo one be heavier than the 4130 tubing one?

mattuk:
both feel about the same weight....

so if we say for example they are both the same frame....

how can i work out if its a screamer or freestyle       is cromo magnetic?      cause still isnt i believe?  thinking back to when they used to do that recycle cans thing and if it stick you could recycle cause it meant aluminium... or something like that
