Come on guys you can`t tell me no one on this site with the knowledge most of you have. Never scratchbuild one of this or just don`t want to share your knowledge

never tried - got a start on one A-arm and it didn't go well - at that point, realized that making one should be easy but making the second to match was a bigger challenge... I think it would take some serious fixturing to pull it off.

I don't think there was much change in the front suspension between the 1980 and 1984 in pro-stock. Would it be possible to get the suspension parts that you need from the 1984 Rehr-Morrison Camaro?

just $.02 (or less)

There are a couple of vids on You Tube. Just do a search. They should get you started. I've not had to make any myself.

Do you have a photo of the 1:1 part?

I guess you'd get more answers if this was posted in Drag Racing Models.

I don't know the best way to make those, as I have never tried building them. I'm interested in hearing the answer, though, when someone says it.

Here is a photo of the A Arm would someone scratchbuild this any help would be great.

1.6mm styrene rod glued to a square of sheet styrene then the excess cut off. Hole drilled with pin drill reinforced with PE washer. strut and coil over is a unit from Future Attractions.

I figured this out by looking at 1:1 stuff and making parts that went in the trash until I got it right. That's what scratch building is. They don't make this stuff so it's up to the individual builder to figure it out.

I have never done one yet but it's not rocket science so it can't be that hard.

First of all, do a google search and find pictures of the part you want to do and study them closely...or even better...look at a real part,... try to replicate it with Evergreen or Plastruct rods, tubes and sheets to do the shapes you need, if you have a real part available you just measure the thing and divide the measurements by 24 or 25 depending on scale or if you dont you have to wing it a bit more and test fit often...and you might not get it right the first time.
Another way is to copy an A-arm from a Revell/Monogram Pro Stock kit chassis...they don't differ much and looks basically the same from the early 80's up to today.
That's what scratchbuilding is all about...trial and error, and you try until you get it right so you might have to do a couple wrong ones before you get one you're happy with.

Great work there Dave wish I knew how to solder like that thanks for sharing

[comp1839]

john, learning to solder is not very hard. you can read all you want about soldering but, 9/10's of the equation is, getting in there and doing it. learning what works for you can only be done by actually soldering. i use a soldering gun, an iron and a small butane torch. knowing where to use each and how to apply the heat is a matter of feel. knowing when solder is about to go molten is something you learn by doing. trying to learn advanced soldering techniques without you knowing the basic ground work, is a waste of your time and the time of who ever is teaching. my best advice would be, get your feet wet, master the basics and then ask the questions. practice, practice, practice.
