How to reproduce parts.

[jeswinehart]

With these Tecate coolant bottles I'm doing a run of the total mix is 230 grams of BJB' TC-878 that cures clear. I use 3 small drops of white to get the translucent effect need.
Those colorants are powerful !

Hi Shep & Jeswinehart

I ordered a small starter kit from smooth on to try make the cr80 back plastic plate if my deal falls through with a guy that is a big time honda collector of all types of bikes,atv,atc and he has a ton of NOS OEM parts that he has stock piled years ago. So, if this deal doesn't pan out I will then try make the back plastic plate. But I was curious what color pigments you used in your honda atc passion red color scheme for your plastic resin mixture? I understand if you don't want to give out your exact honda atc red color recipe but if you could/would let me know what color pigment you use in the recipe that would be awesome(i.e. used alumilite flo red, white, black, brown color pigments in mixture etc?)
Thank you.

Please keep us posted on your work Xman ! I am sure Shep is just as interested see'ing your progress as well as others.

I found the alumilite flo-red to be more of an orange, (pic) also alumilite red to be more of a maroon in color.
BJB enterprizes has a nice looking cherry red that i’m trying next but only sell it by 4ounce at $30 a bottle.
This color chart is BJB’s
Hope this helps you 350xman.
Alot of trial+error, your A+b total mix size will determine your amount of color added it will teach you to have some patience
One more quick pic, its a fail of alumilites blue with a couple drops of white sometimes 2-1/2 minutes goes by way too fast!!!

Hey Guys

Thanks for the info. It will help me out with a good starting point. I ll post some pics once make a small mold and play with the smooth on colors in some small batches and will post them up once I get the smooth on kit sometime this week.
I just assumed the honda red would have some black color pigment in it because its a bit darker then bright red/normal red. I also thought that you would always have add alot more of the pigment colors but it seems their pretty potent.

John, just recieved some of bjb’s Cherry red- I have to say I like it... right out of the bottle it’s almost a perfect match to Honda shells. .
I’m Patiently waiting for 350xman’s progress?
Oh and I gotta add pics-

Edit: an hour later cured test piece

[big specht]

It does look real close just maybe alittle to red than the oem color. Was that a cured test piece there ?

[Shep1970]

Just poured as pics were taken- but sets in 6-mins, so maybe 3-mins in mold, had to run out the door to take son#2 to dentist. I can’t wait to get back to check it. I’ll edit my last post with cured color (in an hour maybe)
Oh/ this mix is the 65d I’m not using for the shells but part a+b are the same color as shell mix I’m going with so just experimenting with it (I know it’s confusing)
65d - 6 min
Mix I’m using - 2 min set time

[jeswinehart]

Hey Guys

It s been a while since I had time to get onto the site to see how things are going... Nice work shep!! The headlight shells look great. your right that bjb cherry red looks very close to honda atc red.
Sorry, to disappoint you Shep but my mold making is right now on the back burner because work has been crazy busy and then my other part time/sideline Mechanical Engineering consulting business has explode way to busy... not enough hours in the day for my full time mechanical engineering job never mind trying to squeeze in time to do some mold but do them correctly... But I did close the deal on some nice vintage oem parts from seller overseas and just finalizing the shipping/importing... hopefully i can get those parts by my summer holidays in july and be able to some repop molds/parts. but i ll make sure to post some pics once things settle down at work in a few weeks... right now I am living vicariously through you(shep) and jeswinehart as master mold/part makers... keep it up!!!

Hey Shep

Just out of curiosity how many drops of the cherry red did you have to add to get the color that close to honda red... I did some small sample cap lids with the red pigment that i received from smooth on and its way to bright for honda red but i guess i just gotta keep playing around...lol

I didn’t care for smooth on’s Sample pack colors personally they never seemed to mix to well, but will work to play around with. How many drops do the shells take, no drops it’s more like a half teaspoon per 500grams (16oz)
Bjb’s cherry red as I’ve found is the only red pigment in this shade of red that’s out there.

I do hear you on work getting busy and less free time.....I just ordered some yellow casting brass/melts a few hundred degrees hotter than aluminum but I can’t wait until it gets here to cast some (different hobby but the molding is basically the same concept. Now if I could cast metal molds for plastic/rubber parts that’d be interesting....

Hey Guys

Just curious if using some type of vibrator method would get rid of the air bubbles out of your plastic cast piece that is to big to fit in a pressure pot? Have you guys ever tried to do this and if so did it work or not work? Thanks.
