FORD MODEL A Transmission cutaway pt 2 CUTTING AWAY 734 tubalcain

this is a four part video series on the ford model a transmission and how to make a cutaway howdy again it's mr pete welcome back to my shop and this is part two of my video on the model a ford transmission and how to make a cutaway so in part one if you haven't watched it i disassembled the transmission that looked like this into all the components everything has been cleaned some parts even painted but the essence of this chapter will be to decide how to cut out the case to best show the gears and how this thing works should i cut this side or this side or just little windows in here i'm really not sure how to do it but i'm going to give it a try here and i hope it turns out so stick with me for these following three chapters in about 1954 when i was 11 years old my dad loaded up the family not to the 51 plymouth but on the rock island rocket and we went to chicago a two-hour ride arrived at lasalle street station long since been demolished took a taxi to the museum of science and industry it was just a world of wonder for you and i think my dad was trying to stimulate me and my brother and he certainly did and i remember loving all the split displays where you could push the button and watch parts rotate and there were many cutaway models there some of them i know were from international harvester which was a local company in chicago and i would watch those chrome plated gears and painted parts rotate and i was mesmerized by them and i still am in fact if you've watched some of my other videos i have about 10 probably where i made cutaways on various things i don't have them here to show you i put them out on loan to a man and they never came back and probably never will but if they do and i would like to put down in the description some of the uh video titles if you want to go back and see some of my other cutaway videos so all right enough gabbing let's get to it okay to repeat myself in part one i disassembled the transmission i cleaned all the parts and that took a lot of time this was really greasy and filthy you saw it and i even started to paint some of the castings i may have to paint them again because they're going to get all scratched up and i decided to use this rust-oleum and it's called hunt club green it's not quite as dark as i wanted but that's all i could find at farm and fleet and i thought i'd show you before we get started here some of the wear on the gears probably still usable a lot of burring here so it's rougher in a cob all the bearings look pretty good that gear doesn't look too bad but anyway all of the parts are in still good usable conditions somewhere on the forks and particularly in here but you know no telling how many miles this transmission had on it remember these ford model a's were only 40 horsepower and went about 45 or 50 miles an hour maximum and probably rattled your teeth at that so uh there wasn't a big strain on these transmissions and it's really quite small and compact isn't it you know what i've thought an awful lot about this and i'm still very tentative on where to cut it and how to cut it i guess i'll use an abrasive grinding wheel on my four inch grinder but i think this is the side i would like to open up in a window and using my soapstone here just showing you that i probably would cut it down there and then across here well it looks pretty sloppy and maybe all the way down to here or something like that possibly come out a little farther or maybe i should also come out all the way to the top and remove this rim part right here and all the way out to the front i really don't know yet but i think also i will cut up into the tower here a little bit so that the spring is exposed and at least one of the rods that way you can see the shift fork so i don't want to take away the structural integrity of the whole case by cutting too much away but yet i want the window to be large enough to see and i know what's going to happen since i am so tentative by nature that i probably will open it up and then cut it again and again and again and that's why it takes me so long sometimes to do a project or a video because i am incredibly indecisive if you will so let me lay the tower aside and then looking at it on the other side i really would like to open up remember this is the reverse gear the reverse idler gear that is in here and from this side you're not going to be able to see much of that so i think i would like to also cut a window in to this to expose that gear and probably clear back to here and down there i don't know pretty hard to decide that's going to be pretty easy i hate to take this off because i just think this is such a beautiful casting and think how the dead pattern makers made these uh patterns and the core that went into here i'm sure they had a whole team working on it but it would have been quite a job and you know they didn't have 3d printing and cad and all that back then so i'm sure there were many many and master patterns made and then working patterns sent to many foundries besides the foreign foundry because a lot of these were made overseas too now i don't know if ford shipped the parts over there or if they did some of the foundry work over there in europe as well but it's an interesting casting really looks so small compared to the assembled transmission doesn't it all right i got to quit talking about and actually do some cutting i'm ready to commit myself all right my first cut will be along the chalk line that you see right there and you know cutting cast iron or machining or whatever you do it's a filthy filthy job because of the graphite so i'm going to be doing most of this out in the grass and my yard consultant told me that my soil is very much low on iron so we'll give her some iron here i know roses need iron too maybe i'll do it near my wife's rose bush and how will i cut let's take a look at my tools okay this grinder is from the great freight store and it's the second one i own the first one was so bad that you could use it for 30 or 40 seconds and the relay would cut out the overload and then you had to push this yellow button here and you could get through a job if it was a small job but i gave it to tommy i hated it so much so then i got another job where i needed this type and i do have an air cutter for mufflers too but my compressor cannot keep up with it so i'm going to try this again but i did try this once before a couple years ago and i do believe it also cut out because of the incredibly poor quality they must have had a lot of feedback on that but they didn't care enough to fix the problems you know it's just it's a piece of junk is what it is i have at least eight maybe more side grinders four four and a half inch and this might be usable also it's a real thin blade that i've got on here right now this one's about brand new the guard might be in the way but i'm like you i'm very hesitant to use a tool like that without a guard so we'll see how that works and get back to you in a in a few minutes it just quit were you timing it look on your time bar there and see how long that lasted before the overload kicked so now i will have to reset it and of course it's unusable oh wrong button that's this one [Applause] let's do it again that's it should i just throw it right in the trash you know where i bought it don't buy one of these [Applause] okay that's going to do the job pretty well if i only can stay at least near the line drum roll if you please [Music] well there's the first window i tell you what that dewalt that thing cuts like this is soft butter margarine soft margarine so remember this is tentative as i've said five times i know i repeat myself you will too when you're ancient like me this is crooked as the dog's hind leg and probably will be ground or milled or cut again and possibly this bottom part should be a little more down to the bottom and i don't know about anyway i'm going to put a few gears in there right now to see what it looks like and then i'll go back and i'll probably should do this first cut a window right here you know what i think i'll do that right now at least a partial window another drum roll please and a lot louder than last time all right it looks something like that with the reverse idler gear installed matter of fact that looks exactly like that and i would like to open up this more later maybe to even expose part of the shaft all the gears are assembled and i got to admit i'm liking it now the question is put it in the comments what gear am i in that's irrelevant i'll have some more quizzes like that after part three but you can see that this gear is hidden from this view as the main drive gear is for that matter so this has to come out or at least part of it to make them visible doesn't it i could go a little bit farther on the bottom here too to expose these gears probably not necessary but definitely along this line here another oh three quarters of an inch probably will do it but it's looking pretty good did you get any fish last night jordan no no all right see a little while after i trim some more of this out and soften the corners make it look just a little bit better but it's coming along nicely isn't it now we got a picture window i'm down in the basement now i wanted to open up this hole for the reverse idler gear and i wanted to be able to see what i'm doing so as i start to mill this it will just be very apparent and easy and and clean cutting and all of that so look at the setup that i made that setup alone cost cost me 30 minutes out of my life most of the time looking for fasteners and i was able to thread regular american threads in standard threads into the cast iron of hanks i think i'll force a little lesson on there right now and i'll make it real quick and it's all about cast iron and what a miracle metal it is and some of the characteristics are that it's relatively low in melting temperature at about 2200 degrees it's highly fluid with great castability excellent machinability as you'll see in a minute if you have never actually worked with it great heat transfer typically in an engine to transfer the heat through the coolant and so on it's very abundant in nature and relatively low in cost the biggest disadvantage it's incredibly brittle as you know and the swarf and the dust is extremely messy okay art fern here again notice my setup here angle plate with two bolts holding it to the table and then two bolts into the casting itself not quite enough but i have to worry here about the alignment of holes and the availability of the slots and all of that and let me show you what i did on the other end i'm cutting with a 3 8 end mill so there's not a lot of force on the work here but i've got a toe clamp here into one of the big holes and that should prevent movement and chatter let's get started i won't show the whole thing okay the gear fits in there like that and remember i wanted to show part of the shaft so i'm going to mill about halfway into this hole that holds the shaft and you can see a line that i've drawn here and i'm going to clean all of this up here it's very rough and sharp because it was ground and matter of fact it's kind of wicked [Music] [Music] so well there it is you see it'll sew a part of the shaft that's what i wanted to show got a deburr in there because it's still kind of wicked clean up and i think the job is done well you know what this is going to turn out to be the longest chapter i thought it would be the shortest chapter but all of the cutting is done i'm ready to mask it and paint it but wait i haven't done the tower yet well i've been at this for about eight hours and i'm pretty hot and tired i'm gonna barbecue some chicken wings and i'm not going to show it to you either but i think what i'm going to do is go ahead and mask this off and paint the bottom casting here off camera temporarily assemble it and see what i want to cut out here on the tower to show the working parts of it and the forks and everything so i haven't decided on that yet but i think that i came to a good decision down here as far as where i was going to cut out the main casting so well i'm not crazy about the color but that's what it looks like so far perhaps the inside should have been painted white sorry but i lost most of the footage of me cutting the main case but on the tower here i plan on cutting it along here up the tower itself and across down and exposing all of that area that'll be my initial cut and then i'll take it from there if necessary and i most of this can be done on the vertical band saw but this will need to be done i think with the grinder okay that really opens it up doesn't it and i think i will still now as just mentioned cut out this portion of the tower here and you'll be able to see the spring is probably unnecessary again i got to use the grinder for this let's see if that'll pop out of there hot there we go well i know the safety nazis are going to crucify me for taking that guard off but so be it that's what i had to do to get the job done now the dremel tool clean that up a bit and degrease it paint it and it's ready to reassemble in the next video lots of still pictures at the end of this chapter so be sure and check them out these are the pieces that are removed for the cutout and it's about two pounds worth well that concludes this rather lengthy chapter of cutting away again i thought it would be a very short one but it didn't turn out that way so join me in part three or chapter three where i reassemble the unit and talk about the different components see you then as this is mr pete you
