geemoney Posted February 12, 2013 Share Posted February 12, 2013 Thanks Bill. This is the beginning of the intake manifold. It is all brass soldered together. Mounting surfaces are acid cut and the tubes are just K&S stock cut and machined to fit. This is the carb master and manifold dry fitted to the head. please xplain to me the "acid cut" can i do this? your work is excellent!

vintagedragfan Posted February 13, 2013 Share Posted February 13, 2013 you make it look easy Mark, that is fantastic work, can I ask what you used to cut the tread on the master? Quote Link to comment Share on other sites More sharing options...
Scale-Master Posted February 13, 2013 Author Share Posted February 13, 2013 Just milled it on my Sherline with a 1/32 inch end mill. No CNC, just planning. I added the sidewall detail and lettering… Quote Link to comment Share on other sites More sharing options...

Scale-Master Posted February 14, 2013 Author Share Posted February 14, 2013 Thanks Bill. I am pretty close to being done with the master for the Weber carbs. There’s about 60 pieces to make this part, maybe a few more… The hardware will machined for each individual carb after I cast copies.

LAone Posted February 16, 2013 Share Posted February 16, 2013 Holy bleeeeeeep! That tire detail is insane man. Shoot me a link if you plan on selling some carbs..... Quote Link to comment Share on other sites More sharing options...
Scale-Master Posted February 21, 2013 Author Share Posted February 21, 2013 Thanks guys. While I'll be casting the carbs, and I can make more than I need for this car, without the machined details they won't be complete or look right. I use Legos to make my mold frames. (The plug in the center of the tire master is made of Renshape.) Not only are the Legos easy to work with and reusable, they also can be stacked to fit more molds in the vacuum/pressure vessel. This is the rim master on top of the tire master to cast the first half of the molds. Quote Link to comment Share on other sites More sharing options...
LAone Posted February 21, 2013 Share Posted February 21, 2013 Sweet set up. Ah I don't mind it not having those fine details as they can be added later anyways.. Quote Link to comment Share on other sites More sharing options...
Mooneyzs Posted February 21, 2013 Share Posted February 21, 2013 Mark... looking good. Can you take pics of the rim and tire molds when u are done. I am curious as to what they will look like.

Scale-Master Posted February 21, 2013 Author Share Posted February 21, 2013 Thanks Chris, yes they are two part molds. And yes I'll take some pictures to share too. Quote Link to comment Share on other sites More sharing options...
ScrappyJ Posted February 21, 2013 Share Posted February 21, 2013 Looking good, Mark. I like using the legos too, for those same reasons. Besides, it's another reason for me to play with legos again. Quote Link to comment Share on other sites More sharing options...
Scale-Master Posted February 22, 2013 Author Share Posted February 22, 2013 Here is the mold and a casting from it for the outer rim for the wheels. Quote Link to comment Share on other sites More sharing options...
Harry P. Posted February 22, 2013 Share Posted February 22, 2013 Awesome! You are a real master craftsman. Maybe I missed it, but how did you create the sidewall lettering on the tire master? Quote Link to comment Share on other sites More sharing options...
Mooneyzs Posted February 22, 2013 Share Posted February 22, 2013 Hey Mark... thanks for sharing the mold. It looks great. I do have a dumb question on the mold. Is there a spot on the mold where you are pouring the resin in or do you pour the resin both halfs and then put together. I guess i am wondering how you get the matung surfaces of the two halves so smooth as well. Keep up the great process. Quote Link to comment Share on other sites More sharing options...

This one has a fill gate and I prefill the mold with resin before putting the halves together, then I "top it off" through the fill gate. I think the part about the smooth mating surfaces you're referring to is more related to the mold construction than the casting of the parts.

Very cool on filling the halfs with resin then topping it off thru the fill gate. You are correct about the mating surfaces. When you had shown us the mold box you were creating with legos I was trying to figure out where your parting line was gonna go for the two halves. Keep on trucking. And I look forward to seeing more on this project. Edited February 22, 2013 by Mooneyzs Quote Link to comment Share on other sites More sharing options...

Scale-Master Posted March 2, 2013 Author Share Posted March 2, 2013 Thanks again guys! Yeah, parts count... The last one, even though kit based, had a couple thousand parts (mostly machined) added. Here is the first cast tire on the first cast rim outer. I cast both parts from molds I made off masters I created. The tire is hollow and easily stretches over the one piece rim. It is so soft and pliable that it should “squat” under the weight of the car. Front: Back: Quote Link to comment Share on other sites More sharing options...
Alyn Posted March 2, 2013 Share Posted March 2, 2013 Great work, Mark. I love the depth of the details on the tire. Taking the extra effort to mold the tire hollow is just another factor in the extraodrinary results you achieve. class continues ... Quote Link to comment Share on other sites More sharing options...
