Carbide bits made for aluminum can be run at elevated speeds and leave a brilliant finish.

Enjoy it!
as I remember, cause it was 26, 27 years ago, I set my head speed at 600, for brass and aluminum, it cut well and clean and smooth so I left it there, for harder stuff I just hand feed slower. I have 6 or 7 extra gears for different speeds and threading, but I have not yet had the need to cut threads in all this time

Speaking of making threads reminds me of a story from back in my misspent youth. My best friend in high school Kenny was able to get a job at a fire suppression company thanks to the help of another friend of ours Tommy. Well this company's specialty is fire sprinkler systems and Tom and Kenny both worked in the pipe shop cutting and threading assorted diameters of pipe. Kenny was a big strapping boy of 6'8" and 275 lbs. and he was know to always wear western shirts and jeans. One day back in the shop Kenny is running the 4" threader and he gets a bit sloppy with the shirt sleeve. The 4" machine gets a hold of it and starts flipping him around in circles and he starts to holler bloody awful murder with what little air doesn't get knocked out of his lungs. After watching about 4 revolutions Tommy stops laughing and kicks the machine off. Kenny was able to started to see the humor in it after about 3 r 4 months. Tommy never would let him for get about it either and of course neither did I.

The pipe shop would get football players coming around every summer to work thinking it would keep them in shape. Kenny would watch them like a hawk because the old wench truck (A 1950s model) had a bad habit of kicking the wench in neutral when a load of pipe was left hanging. Sure enough every one of these gridiron Einsteins would always manage to get under the hanging pipe. After the third time warning they got Ken's favorite safety demonstration. He would put and empty 55 gallon drum under a load of pipe and kick the wench into neutral crushing the drum like a beer can. Funny thing they would never show up for work after witnessing his little safety demonstration.

Less funny was the shop foreman Earl's accident, he threaded an arm all the way up past the elbow.

The funnest accident was the Stress and Force engineer Curly's accident. Curly comes out of the office to see how things are going on in the shop and stops to watch Tom (His future son in-law) cutting some large thick wall pipe with a cutting torch. We Tom would cut little sit the torch behind him on a stool and go to move the pipe. Well Curly is too busy watch Tom to look and backs up and sits down on the stool. Needs to say he got back up considerably quicker! I heard it was quite funny watching him with his last end over the fence sticking in a slop sink cursing blue streak.

I figured I must have been marginally smarter than Tom and Ken or just a little lazier or maybe a little more cowardly because I never even thought about asking for a job at that pipe shop even though it paid a lot better than I was making. I'm convinced if I worked there if the threading machines didn't get me the wench truck would have.

Flyer, you should write a book, good stuff.

You asked "Have you ever seen it work?"; the answer is yes. I have used that dimpling technique a few times myself on axle shafts that have had spun bearings. I use a different technique, lots of dimples even spaced throughout the bearing mounting surface of the shaft. I have never had one fail but then again automotive wheel axles don't spin at 10k + rpm either.

This fa115 crank doesn't appear to have spun a bearing, just appears to have been sized up.

I have seen that done hundreds of times but never, ever done it myself. Loctite bearing mount was the only method we were ever allowed to use in the machine repair trade. Failing that, plating or welding, followed by machined sizing were in order.

In the case of that shaft, there would be no real good reason to do it.

Gary,
Is Loctite 609 retaining compound the stuff I need or would you recommend another product?
Currently the bearing mounts the crank with a very slight interference fit.

A slight interference on the shaft is all that is needed. Better to allow for some float. A certain amount of creep is okay as that permits end float take up. Excessive spinning is not a good thing but is very rare in this setup, usually results from a very near siezed bearing.

Gary, what is it people use on the cylinder sleeves when replacing sleeves, my friend (Jack) built oval racing engines here in Vt, he use this stuff that was blue, but it was almost clear. he also used it on screws to hold baffles in aluminum rocker covers..
LOL one time Jack built a Chevy 400 SB for open class dirt track oval engine for a guy and the guy over revved it on the 3rd run and an Cam bearing spun, Jack never liked the Chevy 400 SB for that kind of power

You referring to dry sleeves where the block is bored and a new sleeve inserted? Permatex makes a sleeve adhesive, blue in color like you described.

Loctite- Permatex, same company.

If it was watery and blue it may be copper sulphate solution. We usually did them dry.

Hopped up small block 400s could make a lot of power but not for very long. A lot of stresses on too little iron.

The 400s would warp, leaving the main saddles and sometimes the cam bearing bores distorted. We line-bored more 400s than any other V8 when we were operating the automotive machine shop.

(You referring to dry sleeves where the block is bored and a new sleeve inserted? )

yes-em I was..

400 SB: the stroke of a 396 (3.375), the bore of a 400 (4.125), many don;t know that the 396 BB in it's 3rd or 4th year was really bored to a 400, yet sold as a 396, the numbers "396" just sounds cooler I guess.

my friend Stan built a 400SB Chevy, it had street heads that were rated at only 4HP less than AFR heads (Air Flow Reach) were at .600" lift. my friend Jack did the machining and went threw the heads, Stan only paid $200 for the heads. I picked the cam, Jack figured the engine around 450HP, it was in a 79 Camino, after a few years Stan sold the car, one day about 2 months after he sold it I was with Stan and we saw the car at a truck parts store so we stopped and talked to the guy, and I tell you I saw it put down 200ft of rubber, and man it was off the line and out of there. I have all ways wondered how fast it would have been off the line with bigger tiers and driven for effect. . the thing is, from about where that guy came off the throttle to the end of the road was about a 1/4 mile then there is a right turn, well I left in my van right then and when I got down around that corner there was a cop setting there off the road, he must have heard that 400 coming alive. that guy soon later LOL blew up the 400.

that 400SB^ was built some 20 years ago, it had a Comp Cam, sorry I don't remember what the lift and duration was. back then I had read a lot about Cams so Stan picked the lift he wanted and he asked me to find a cam. I picked 2 Comp Cams then I called them and they told me what one to buy out of the 2.. I don't know if Jack's guess of 450HP was correct or not, but it sure did go that day, but today's Cam profiles are even more powerful when considering the same lifts

Stan's is 5 years older then me, his father had his own car repair shop, so Stan has been a mechanic all his life, Stan still owns that shop today!!!!, he bought it from his mother, lives there too. he had all kinds of muscle cars over the years, 69 383 Road Runner, 67 Cuda, 69 442, 72 Nova SS and that Camino was the last one. I tell you Stan can really drive too, he started driving a 9y.o.. back when I had my Nova he once took me for a ride in his 442, it was about midnight, he pulled up to the hi-way and stopped, he looked to the left and then looked to the right and back to the left, he then said "if this bothers you just tell me so", I didn't know what he was talking about, I was 18,, he looked again and then the Revvs come up and the next thing I know he dropped the clutch and does a full birdy to the left, then slams 2nd and swings the rear end around and does a full birdy to the right in 2nd gear, then straight down the hi-way about 100 ft of rubber. at that time I had only known Stan about a year. Stan lived about 30 miles from me, so the next day I went and check-out the rubber ( 2 circles of rubber and 100ft down the road) with a big smile on my face. the 442 had a 455 in it then, later LOL he blew it up and put a 400 in it.. a few years ago I asked Stan why he didn't oval race because his father did race oval dirt track for some 3 or 4 years way back in the early 70s, Stan said "what, and get stuck going in circles, I like going straight fast"


I guess that's it for tonight, later my friends

Jim

Dave,

The box of Saito parts and the first installment of metalworking goodies went out yesterday. You will be a very busy fellow!

Wasp,
Very well aware of the later 396 growth but it was 402 inch, not 400 and it was still a big block, not the small block.

New parts came from HH and Boca for the 115 yesterday. As usual the antifreeze/crockpot treatment left the rest of the engine parts bright and shiny, should look brand new once assembled this morning. Bench testing this evening if I'm not too tired after laying 110 concrete blocks today.

FG21 update: Installed new pushrods, adjusters and tappets last weekend and break in went well. I only had to take up .0025" valve lash on each adjuster after a full hour of run time. The engine runs glass smooth at all rpms.

FG21:
Rcexl cdi set to 29 btdc
89 octane gas /no ethanol
20:1 Stihl Ultra HP oil
15x8 APC prop
8850 rpm peak
1600 rpm idle
2.021 hp

Eight or twelve inch? Lightweight or concrete? All day?


BTW Dave,

That box on the way weighs about 25 pounds, not quite the weight of a 2 cell, lightweight cinder block, but a LOT of big block Saito stuff. There are several cams in there.Check them out. I have replaced very few Saito cams and lifters for wear but never had to replace one from any form of rust.
Every one I was able to salvage by cleaning. They are made from sintered, pressed metal and, so long as not grooved with wear, they live on forever. Don't be afraid to use them after cleaning.

8 inch, lightweight and yes, almost all day. Today is the top course (145 lin, ft.) over a 6 step footer for an addition. I'm not a block layer per se, I'm a remodeller and it do all myself from the ground up. I'm sure you and your Dad could easily lay twice that much block in a day.

Best when laying between knees and nipples I am no record setter, never was, certainly not today! Most of my experience was setting up and loading scaffolding. Keeping block, brick and mortar to 3 masons AND moving the scaffold was enough! When you get three jacks high and tumble it all by hand, it gets handled about six times before they get to use it!
But Dad certainly started at around 300 and I had seen a few days around 500 (12 inch)

Anything over 200 blocks a day is really moving, My record is 120 in 6 hrs. and I was wore smooth out! Can't imagine 300 much less 500.

I was taught by my Charlie, a union mason by trade. His record at work was 100 12" blocks in one shift, not because he couldn't lay more than that but because that's all he was allowed to lay by union rules. His story, not mine.

I actually enjoy laying 8" lightweights knees to nipples high but that almost never happens in my line of work.

Dad was well known around here for fast, clean masonry. He was built like a block house and not an ounce of fat. His work day was eight hours of solid work. I used to keep close track of the block as I was hauling then from the cubes to the line. Most masons I worked with would do about an average of 250 8 inch.
Common brick would get about 900/day.

Below grade around here ( basement) iirc were 12 inch concrete at about 50lb each. Top course were solid top FHA and probably closer to 65lb !

Believe me, I was hustling to keep up.


Listing kits this week end, get your Saitos ready!
