Robert, Your work is "All about the details"! I have looked at a alot of Mack Rs. And never noticed the difference in hood bolt patterns? That's why your model builds are "Over The Top"! Standing by for the second installment!
They sure were - and are! Earlier this week a scrap bin was dropped off at one of our fire stations for clean up, roll off truck was an '89 RB600 still going strong in 2024!
Thank you Matt - only regret I have from my few years driving Mack R's back in the mid-1990's is not taking more detail photos then, because at that time I wasn't active in the scale modelling hobby. Good thing is the number of on-line for sale ads available now as an alternate source for references!
Curious how at 6:20 you are talking about the pre-73 cab (which I really appreciate the detail you put into it!), but then you talk about the four-bolt hinges, suggesting it may be aftermarket. Look again, there are seven bolts on each side there! ;-) Not trying to throw shade; simply hoping to clarify some potential ambiguity. Love your work, and I'm fixing to use ALL of your tips on my next (first) semi build, despite it being a White Western Star. Your videos have pointed out what to look for and how to fix it. Thank you!
With the last RD's being built in (I believe) 2003 as 2004 models, and the first R series trucks built for the 1966 model year, that R cab had about 38 years in production! That's a long run by any standards and even longer than another well known and very popular truck cab, Ford's L series.
Tichy Train Group are the ones I use. www.tichytraingroup.com/Shop/tabid/91/c/ho_nbw--rivets/Default.aspx There is a range of sizes from .020" up to .080", most of the time I use ones from .025" up to .060".
Question about the amt Mack r685 model. After looking at pics online, I've noticed that every model displayed with the hood open, the hood doesn't fully open. The hood is always roughly at a 45°ish angle. Im no Mack guru mechanic, but Im pretty sure it opens further than that. The question is, have you ever encountered that with this model? I ask because Im about to build one and I like to prepare for future problems. I was just wondering if the model comes that way and if it's an easy fix. TY, sir.
Yes, kit hood hood hinge design does limit the hood opening angle and if I recall (from my days driving Mack R's about 30 years ago) hood does open up to almost 90 degrees on a 1:1 truck. I haven't made major changes to kit hood hinge on previous models (on most recent one in Conrail Mercury markings I re-used kit hinge, only changing mounting points to hood , you have got me thinking that it is time to at least mock up a frame/cab/hood and look at how hinges could be reworked to get pivot point higher, allowing hood to tilt 90 degrees. Something along the lines of hinges for the AMT W900 th-cam.com/video/fqfQh3P7HdI/w-d-xo.html
Have question about fiberglass. Any idea how you create the rough look like it is under the hood? I'd like to make the van from Cheech and Chong, truck hoods would have the same effect.
I have created this texture two different ways, both were methods of creating cast armour texture I saw in Fine Scale Modeller articles. One way is apply solvent cement to surface and stipple with stiff paintbrush. Slower drying cement like Testors works best for this. The other way, which I used on the Mack hood, is lightly running a 1/4" diameter ball end cutter in Dremel tool (I believe Dremel calls it #100) over all surfaces to create a roughened texture. This works well for removal of ejector pin marks on hood underside as well.

The R600 Mack was a real work horse.
They sure were - and are! Earlier this week a scrap bin was dropped off at one of our fire stations for clean up, roll off truck was an '89 RB600 still going strong in 2024!
Excellent narration and photography as usual Robert. Thanks for sharing!

These are almost like the old Beetles or GM fishbowl buses, similar yet different. Only a trained eye will see the differences.
nice!
Where do you get rivet heads?

@@brsnorthernhorsejourney3579 Thanks, I'll try it. I also had a suggestion to use wet wipes or tea bags and glue them on with white glue.
