I had this exact problem a couple of days ago trying to repower my drill press (same sizes and all)

Easy fix...

I will come out of forum retirement very briefly to share that these guys are now my go-to tooling supplier.
The end mills are Aussie made and cut fantastically well
The toolholders and inserts ive...

Now that's a knife!!

Hi Phil

Im not a mechanic but i do have a fair bit of head gasket experience. From your description and video the only 2 likely scenarios are the gasket blown from a cylinder to a water jacket (or...

+1. Had an aluminium chip stuck between my teeth a few weeks ago. NFI how it got there, didn't feel it go in!

Thanks for all the replies guys. Unfortunately i messed up my estimations on piston-to-valve clearance, the stock pistons wont clear the 2mm OS valves at my compression height :s
So the head isnt...

Thanks ray, very helpful. Ill give it a crack once i have finished 'turning' them on the 'lathe' ;)

WRT to the application and issues with the parts failing -of course it depends how they fail.

This particular batch are for my own engine, a test bed of sorts, im pretty used to breaking it...

Thanks for the replies guys.

Couple more questions-
How long do i hold them at the Curie point for?
How long do they stay in the quench oil for?
How long do i temper them in the oven* for?
How...

You can see the shims in question to the left in this picture... they are 8mm on the big OD and 2.8mm on the small, 4mm long. Tiny!

Hi guys

I need to harden some valve shims to approximately 60hrc (i think it was hrc?). I had planned on sending these out to the local hardeners, but the 1-2 week turnaround mucks with all my...

That's more like it fellas!

slhouettev8 that is quite impressive mate!
ray, looking good but maybe you can cut a bit deeper or even up the feedrate? chip colors look pretty good... but you were...

Wow. Never thought i would see the word "Niggardly" used in an ebay description. Just wow.

Na no 5331 sorry. It that a silicone sealant or a PTFE type? I have all sorts of silicones and flange sealants here that may be suitable but no teflon stuff.

The bulk of that is gone now anyway,...

Just called the bloke and it is already sold (pending)
Im next in line if it falls through.... would make a great spare machine or drill press etc

No problem Ew, obviously we are talking apples and bananas here :)
I just need something to check cylinder heads and blocks for straightness before reassembly, nothing like the precision (or...

Hi ueee i have to knock up a couple of straight edges for myself over the next few days. I was planning on using 16x50 flat bar and basically just facing off all the edges. They wont be hard to make...

Might be a good time to order those cermet inserts too bob. They'll have no trouble with this stuff.

Not yet. Ill have to make new, taller jaws to sit outside and come over the top. Would also have to take the normal jaws out, which im loathe to do. Is any accuracy lost or realignment needed after...

Had another good haul last week too, not tools but im sure everyone here likes loctite :-)
I sure like having a mate who works for them!
The big bottles of 243 are 250ml! Ive never seen loctite...

Thanks for the heads up mate. I would have scrapped it all, lol!
I have stripped the machine and there is lots of extrusion there. I will list it up on ebay over the next few days. If any forum...

Pretty much what he said....
If you are cutting properly the chips will melt into your skin in a few seconds.
Generally my chips are white right at the cut zone then turn blue after 1mm or so.

I have the 6" anglock from vertex. Its a good bit of kit, and good value. I am amazed how much holding force you can get on such a small area with it. Ive only had a pull out once, which i rectified...

Yeah i guess it depends on the hand drill. My cordless Protool will happily go 10mm pilot then 1" through cast iron or ally without breaking sweat. I recently holesaw'd a 44mm hole through 3/4" of...

Yeah the guy has designed up super fancy billet uprights/hubs but that is a BIG machining job, needs more travel, axis' and skill than i have at the present time.


Anyway, back on topic -have you...

Wow, good guess. It is for a Toyota not a Porsche but you still get 10 points. The 300mm slicks are ex Porsche-cup, so i guess that counts.
The brakes on this thing are so big the only wheels he...

Dont have any known 4140 yet sorry. I have plenty of very hard steel, but i bought a bulk lot of scrap bar stock some time back (at $0.10/lb!) so im not 100% on any of the grades unfortunately.

Hi Ray i rarely drop the lathe out of top gear -1400rpm. Next step down is 900 which doesnt cut as well or leave as good a finish. For the small stuff i use the VFD to increase speed over 1400. I...

20mm BMS down to 11mm, one cut. Approx 1600rpm, hafco al960b, no powerfeed. The finish is #### as it...

Lol, that's not a heavy cut. Crank up the speed and lay into it :-)

Good stuff Ray. Looks as though you may want to increase the spindle speed a bit, if you have it. Are the chips in the background from that cut? If so you are going way too slow. The chips really...

Well i finally have a tools gloat from this week. Friend's brother in law works for a big firm who supply Holden and Ford... need i say more?
Picked all this up for nix, though i did spend a fair...

Thanks for the offer Greg, much appreciated. As usual i am pretty keen to do the work in house (part of the reason for getting such a big mill is to be able to do jobs like this) but if i get stuck...

yep, which is why i want to mount is as square as possible to the original mounting face.



thought about this, but the surface finish off an end mill wont be good enough, nor do i have an...

Thanks guys
Yes i attached the wrong picture first (damn tablet)
Running 4/6 tips in the tool as i am missing parts, tips are cermet which eats through the welds like butter -no way i would use...

As per title, how would you hold this bastard of a thing? Had a lot of trouble getting the turbo flange parallel with the bed and enough force holding the part so it would not move while cutting...

My hafco one used to get quite hot when i worked it hard at high rpm for several hours, until i opened it up, cleaned out the ###### grease it came with and repacked it with moly. After that it was...

I think you would get away with 1hp, but it would be on the lower limit. What you need is the spindle speed. I leave my lathe in top gear @ 1400rpm for cermet cutting, almost regardless of diameter...

You guys really need to get onto Cermet inserts. They are available for most of the standard toolholders if you look around. As long as you keep the DOC and feedrate reasonable interrupted cuts in...

Ditto. It would be a great companion for my Victoria mill.
Alas i dont have money for noodles this month, let alone new toys and a hefty freight bill

No thanks. The bang was violent enough for me to not want that to happen ever again.

Getting that motor to work correctly on the lathe had stretched the limits of my AC electrical knowledge and i...

Yep it made a hell of a bang and took about 2 hours for the workshop to clear of smoke. Stiff drink and new undies needed indeed.

Grahame, thanks for the informative reply. Sounds like a fun job!

Ha, my floor isnt flat, or even concrete! The lathe sits on a sheet of 19mm chipboard which was roughly levelled by hand. Now im only 5'9, but i found the lathe way too low and was killing me to bend...
