Last Saturday I saw an estate sale at a place where I got a lot of Chevy pickup parts several years ago. While checking it out I saw an OMC boat motor and didn't think much about it at the time. I have a couple of extra 153s. Later I thought it might be a 181. I went back today about 15 minutes late. I was a 181 and a guy I know had just bought it. Damn that's 20 free hp.
Well I pulled the rock hard hose and clamps off to sit the hat down on the carb and see just low I could actually get it. Little more mock up, sit and stare. Partially trying to see what the minimal slice and dice route to making it look better is. Even from the passenger side you can’t really see the back half. But I know it’s there. You know how that works. anyhow I did also find that I have another broken lid that is the same ish diameter as the breather top so if the larger breather fits I would t have to start all over. I’ll mock it up this week a little better. I need to raise the top half to line up with the carb hat and take a look at that as well. I don’t want to have a jog in the pipe connecting the hat to the breather because it seems like it would be visually distracting. At the same time I think the top of the breather being even with the top of the valve cover is the best look. always a compromise somewhere I suppose. also need to find an easier to search list of Round air filters. I want to make sure I don’t create a cavity for a filter to fill and then not be able to find a filter that size
I think you are on the right track, a little tweak here and a little tweak there. Still working through bugs on my Chevy and the new rear carb didn’t have room. Smaller booster, a divot here, a trim there, shave this, wiggle that....it’s finally on. I’m confident you will get there with a result you will be happy with
Mock it up with the inlet/outlet on the same plane. I think it’ll work. I’d like the whole thing to sit lower but it is what it is. I could make the section between the bend and the top of the filter housing longer but it kinda kills the nice flow it has. Long as it clears the hood side I think it’ll work fine. I also found a good off the shelf filter via searching summit. I’ll get one before I cement it all just to be 100% sure it all works right
Also seeing metal prices go up I took advantage of a slow afternoon at work to drive over to metal by the foot and pickup metal for every project that I’ve measured for including making a new bottom half of the air filter. The pot lid worked at the smaller size but at this larger size it just does t work for me. I’m going to make an mdf buck and hammer a lower out of 16 g sheet
There we go, couple bucks and they cut everything to my measurements quicker than I could walk to the loading dock. Enough 16g sheet to build the rest of the air cleaner and patch the running boards. Rectangle tube for new running board braces, door sills and b pillar supports, strap for license plate mount and some round tube to make jigs out of. should be set
Getting that under the hood reminds me of my son and I putting the supercharger on his '54 Stude and getting the stock hood to close. The wagons & sedans are 4" shorter than the coupes from the firewall to the radiator. When they put the McCulloch on them they added a hump in the hood and fins and called them Hawks. Nice clean steel, so nice to work with.
I was just thinking today that if you didn’t know anything it would look like forced induction at a glance. Haha. That car is awesome , love when you post photos of it
Started marking my buck for the air cleaner bottom looking around the house I found several table leafs for tables we haven’t owned in years. this one was wide enough so I started roughing it out. my plan is to cut the squares out with a chop saw and then keep cutting corners until it’s mostly round. Then hit it with a jig saw, bolt them Together and make them match with sanding or what ever is handy. One will end up a tiny bit flat on one curve because I didn’t account for the blade width of the chop saw in drawing this out but I had been back and forth on making the top of the buck slightly smaller so I could get to the corner a little easier anyhow
Also ran the numbers after thinking it didn’t look quite right and this is an f1 truck clutch arm. Still long, still gonna cut it up to make it work just right. Just thought I’d document it for the sake of having a note for when someone asks in ten years what it is and I don’t remember
Very hi tech over here. there is a slight bow in them but because they were cut right next to each other they nest just perfect In each other. im not sure that it’s enough to put any crown in the finished product but if it is I don’t think it will be visibly noticeable and could get rid of any possible oil canning so I’m fine with it. should be able to center drill, bolt together and then smooth them out with some rough sandpaper pretty easily. trying to figure out how much overlap I need for the flange so I can cut it out and not have to trim a crazy amount off after forming g
A couple of years ago my son & I picked up a lathe from a sheetmetal shop in California. The young guy that ran the shop was using it to turn round shapes over wood bucks. It was really cool to watch.
Little progress this morning got them drilled bolted together with an indexing mark put a fat washer on one side thinking I should add one to the other as well hand file is knocking it round pretty fast. Probably stick some 60 grit on a sanding block to get the last bit. Not hard making it match the penciled line but keeping the width flat/square takes more attention than I thought it might. easy stuff to chip away at either way
Tim, if you know someone with a belt sander I would encourage you to ask them to hook you up. It will make your work go much faster, the sanding will be smooth and well controlled, and from my experience it will be much easier to keep the width flat and square to the faces.
If you have any drill press/guns you could chuck the center stud and tape the trigger to an rpm your comfortable with and gently clamp in some cardboard/cereal boxboard or a thin cushioning shipping foam and file/sand. That brings in a new dynamic in be careful over the non rotate method that works and can give more than adequate results...I was just thinking out loud...you can use bigger bolts if desired as well of course...
Belt sander would be handy! This is actually going pretty quick, and to be honest I tend to like doing the tedious hand tool route on most things. thinking I should be ready to hammer on it this weekend.
I made a circular top for a stand from 3/4 plywood recently and did pretty much what you did...and it took a while...I used a table saw to rough it to a circle and files, sandpaper and a vise for the rest...
Cool! Most of what I need to knock down is 1/16” tall and not very wide. Thankfully I have plenty of experience making a circle with straight lines so I got it pretty dang close. I’m focusing mainly on the half the metal will draw over because the top is just holding it in place.
I can't wait to see that metal wrapping around that buck/form. So are you just going to shape the flange around the buck via hammer...I may have missed that...I was thinking of a female die and a arm-strong or hydraulic press...but as always what's in the Shop governs direction...I have neither myself but sure have utilized them in the workplace and know of the capability they possess...
I’ll hammer it over using a variety of hammers and spoons/ slappers. Whatever feels right. then hammer/ dolly any additional wiggles that show up after prying it off the buck. I’m thinking a think cut off disc to trim the flange to a shorter uniform height. Or possibly a hand saw with it still on the buck. guess we’ll find out!
I think I already know the answer by so you have a take l table saw? There is a way to make perfect circles by using a pivot hole I. The middle. Si ce you need a hole in the middle anyway for the finished part and to bolt the hammer for together. Sent from my SM-G781V using The H.A.M.B. mobile app
Dayuum, learn a new thing everyday...I gotta make me one of those...thanks @redzula for the tip and you @Tim for passing the buck......Hamb Gospel I say...
