JoeH Posted November 28, 2023 Share Posted November 28, 2023 I see AMT has an R685ST model with the 237 HP motor, but is there one with the engine mounted charge air cooler? Toying with the idea of making a model of my dad's volumetric mixer truck. Quote Link to comment https://www.bigmacktrucks.com/topic/73591-79-r686st/ Share on other sites More sharing options...
JoeH Posted November 28, 2023 Author Share Posted November 28, 2023 Is there a parts source for individual parts like round fuel tanks, engines, etc? Quote Link to comment https://www.bigmacktrucks.com/topic/73591-79-r686st/#findComment-542663 Share on other sites More sharing options...
mechohaulic Posted December 1, 2023 Share Posted December 1, 2023 I will check my "parts department " in the am; might still have a spare 300 plus engine with top mounted tip turbine fan. bought many parts back in the late 70's- early 80's from A I M : late Jim Etter in PA. also bought from Late Dave Natale AITM in NJ. resin cast in 1/25th scale. took a little modifications to make the 300fit . challenge was making alll the intake piping. built an R-600 for a customer. todays world only a couple of people make 1/24-1/25th scale parts most of which are 3-D printed not resin castings. have a couple of builds in progress now which I ended up buying 2 or 3 other scale models to get parts I needed. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73591-79-r686st/#findComment-542744 Share on other sites More sharing options...

Send me some of your ambition ha ha…bob but we ALL know You can do it. not to be a party pooper but the DM 800 was 30+ yrs ago. sorry had to say it. side note ; my DM-800 1/25th scale was from first issue mid/late '70's ;; actually two - one a mixer (as shown on profile) and a DM-800 stretched to fit wrecker body ;; neither of which are completed 40+yrs later.😱 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73591-79-r686st/#findComment-542817 Share on other sites More sharing options...
mowerman Posted December 4, 2023 Share Posted December 4, 2023 OK well I don’t feel alone in this bought the kit used around 20 years ago and it took me at least 10 years to find instructions that it didn’t come with wound up getting them from Chevy 41 …..who seems to have vanished … he had one …. I was very fortunate …. I think the biggest problem is I think about pulling it out and working on it an hour or so I could probably have it done in a couple of weeks. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73591-79-r686st/#findComment-542874 Share on other sites More sharing options...
