It looks like they want to fold fore and aft and the rear mount is the only thing controlling this movement to some degree, I imagine that big lump would have quite a bit of interia under hard braking. As big a fan of minimalist design I am I'd be inclined to err on the side of caution and stiffen them in that direction. I think it's great people should choose to spend money on professional custom cars, I'd love to pay someone to finish mine and go on holiday
If you sent them to me, I haven't seen them. Don't know how that could happen, but I just checked and there aren't any from you. Try sending them again, or email me at kevin@hotrodchassisandcycle.com.
Once again the guys at HRCC amaze us with their knowledge, talent and most of all, the ability to visulize. Thanks Kevin for sharing! I'm lucky I can turn a screwdriver; so I guess that means I shouldn't have the opportunity to own and drive a hot rod? That guy is a dipshit. Thank again for sharing the story & the great photos! Jack
Maybe at a quick glance the mounts look marginal, but I highly doubt there will ever be an issue with any of them as fa as durability go. When I was building formula SAE cars in college, we fabricated everything in house including suspension components. Weight is king, so the lighter and thinner wall tube you could use the better. We made ours out of 3/8" tube, .049 wall, with an insert drilled and tapped for a 5/16 fine thread rod end TIG'ed into the tube. We put a test piece in an Instron machine to test the strength in straight tension. At 6230 lbs, the tube broke at the heat affected zone above the weld, which is many times the amount of force the tube would be under in even the most serious race conditions. The mounts here are clearly made of steel heavier than .049, and I could easily surmise that under even extreme conditions, they would not fail. Yes, the bolts are in sheer, which technically is a poor design. However, the engine could never make enough power (or hook up with that much power) to sheer the bolt off. I'd use grade 8 hardware just to be on the safe side, but given the quality of this build, I'm sure that's what you're using any way. Suberb build quality and engineering, paying attention to both form and fucntion. I'd be proud to own it. Keep up the good work and keep us posted with updates
Very fine execution, thanks for taking the time to show us a build Kevin. The front motor mount opinion poll did help me to examine a "sense" that I took away, of first wondering about for-and-aft loads acting upon the mid-height drilled section of the mount. I appreciated '57's response on his SAE cars. We all learn good techniques from the give and take on the variety of ways to fab some component. Ryan has stood behind the forum, and I hope that all the build projects keep coming.
dig those headers and tube work, great work wish I had a daddy like that, does he do adopt a-rodder for x-mas
hotrodchassis, thanks for posting pic's of your builds..gives me hope that the pile of parts in my garage might look like a car again.
And we're back. I deleted quite a bit of crap. My apologies if the thread doesn't flow quite right. Feel free to send me nasty PM's about over-moderating. See where it gets you. I'm sick of newbies killing threads. Leave thread killing to the pros....
Ok fellas, if you asked me a question and it's gone now, please re-post and ask again. I think they are all relevant, and want to help in any way I can. And thanks to RASHY for taking the time out of his Sunday morning to save a thread. This is Ryans (Bobs son) first car, and Bob wanted it to be special. And most importantly SAFE. Admitting he (Bob) isn't a welder, and putting his son IN a hand built car, I think he made the right decision in having the frame proffesionally built. But us or another shop isn't the issue. Safety and his sons life is. What I posted before was that there are three G5 bolts holding the mount to the engine. According to the ASTM, SAE AND ISO GRADE MARKINGS AND MECHANICAL PROPERTIES FOR STEEL FASTENERS, G5's have a load strength of 85,000 lbs up to a 1" bolt. I used three where MoPar used two on the OEM application. The lower is a G8 (also higher than the OEM application) at that rates in at 120,000 lbs. After seeing GE Turbofans on KC135's in the service, and Turboprops on C130s held onto the pylon with four dowl pins, it really makes you look at design and strength. The photograph of the mounts is a little misleading. They look longer than they are for some reason, and are made from 1/4" cold rolled plate. The lower mount has a shouldered polyurethane insert for vibration isolation. Also, the violence (on the drivetrain) of a launch with an automatic equiped car is much less than that of a stick car. So there is some "sluchieness" where the stick would have much more shock load. Had this been a stick car, the mounts would have been much heavier. And quite possibly even been solid mounted, or have a mid mount with polyurethane bushings.
You know, I forgot to let everyone know that Bob and Ryan are Roseboystoys here on the HAMB. My intention was to introduce them to everyone, and let them see all the great people on here. They usually go to Columbus GG I think, and I'm encouraging them to go to the Rock N Race at Dragway 42, as well as anything else that's hot rod related in their area. They are really great guys, so if you see the car at anything where there might be a HAMB Meet & Greet, say hello to them and show them how friendly the HAMB really is. Viva La HAMB!
Everyone @ Hot Rod Chassis & Cycle..........Rocks...thanks for taking the time to post pics and info........Littleman
Hey Dave!! I told Bob about you. I told him to look you up if he goes to Rock & Race next summer and you're there. Thanks for the kind words!
Rashy............ SORRY DUDE , I must have posted when you was taking out the trash, I'll have to take a typing class so I can keep up in class, Take out my other post if you want ,I'll undrestand, I was trying to help put it to sleep.......Should have know better and sent it to a MOD... I've had my hand internet slapped BEFORE by the BIG GUY and don't want that to happen again..hahahahahahhhhahahhahah Everyboby have a great Sunday ,and again MERRY CHRISTMAS..................
Hey by the way, that dash is bitchin! The side profiles really showcases how well it fits in. When I saw the headers I said out loud "WHAT?!" That will really be a talking point when people seem them. ( i love 'em)
Hi everyone. I am the owner of this build. My name is Bob Rose and my son is Ryan. First I would like to thank everyone for the kind words and compliments on the car. This whole thing just started out as a dream for me and my son. As time went on it seemed this could become a reality. Of course we wanted to build the car in the garage ourselves but obviously we cannot. Ryan asked if we could build something and I told him to come up with what he would like to build and we'll see what we can do. I was surpised when he chose this Model A since we already had one but nothing like what this has turned out to be. By the way, Ryan has a twin brother Bryan (the plot thickens). Bryan and I are also working on a father/son project! Not as extensive as the Model A but we dug a 1959 Ford F100 out of a barn last year and got it running and made some mod's to it like disc brakes, electronic distributor, dropped it 4.5" changed the rearend and tranny. It has a stock 292 Y block. He drove it all summer to football practice and in the fall drove it to school on a daily basis. He got alot of looks from other parents and alot of compliments. We also have an older son Robert who is in college on a baseball scholarship. We haven't started his project yet but we will when the time is right. And of course, we couldn't do this without the buy in and support of my wife and the boys mother, Laura. All I am trying to do is educate the boys on the hobby. I'm not trying to win the "Father of the Year" award. If they never turn a wrench again, at least they will have an appreciation of these cars when they see them on the road. Secondly, they will know when their car needs repair and the mechanic says the brake pads are worn they'll know where to look! All I can say is if you ever get the opportunity to do a father/son or for that matter a father/daughter project, by all means don't hesitate. As far as HOT ROD CHASSIS and CYCLE goes, we could not have chosen a better builder. This is a class operation. Kevin and his staff have been more that helpful and accommodating throughout this whole project. Always willing to answer questions ( and we had alot of them) and took the time to discuss anything we needed. I 'll write more about Kevin and this build when we are done. Finally, it looks like we will be picking up the Model A on Jan. 8th at the Christmas Party at HRCC. Hope to get a chance to meet alot of you there. Can't wait to get the car home and get it finished. Thanks Bob and Ryan PS: As far as the lightning strike goes........very few people stand by me when it starts to rain!
Very cool car. Excellent fab & design work. Personally I don't think the headers and shifter fit the look of the car, too race carish for me, but it's not my car right? It's cool though to see kids this age interested in this hobby, as well as still have a relationship with their dad. From what I read, it's your kids that want to do this, not dad shoving it down their throat, which seems to be the way it is with a lot of parents today. "You're going to soccer/baseball/football/whatever practice today whether you like it or not" Good luck on the project, you should be a proud dad.
Sounds like your family is having a lot of fun and thats the most important thing. The whole build looks great, esp those headers, bad ass!
Cool, I will state again that the fab work is nice Kev. Also the dash is 20 pounds_______ in a 10 pound bag! I know, I am cutting one down for my Tudor as we speak. Amazing how narrow the dash is on A's.
Kevin great work, you guys are kicking ass, Rashy thanks for deleting the drama, including my smart ass remarks... I love seeing this kind of fabrication and detail. It's this kind of sharing that pushes the bar up, that enables us with shops to keep doing what we do...
