Re: Proper grind for a fly cutter?
Dave, Several years ago I bought a set of fly cutters and had the same question as you asked. I did some searching on the internet and found a 3-page guide for flycutter bit sharpening. It isn't meant to detract from the reply Harold provided, just give you some additional pictures/explanation of th...

Re: small cutoff saw
Being the frugal fellow that I am, I bought the Harbour Freight version about 4 years ago ($59.95 on-sale) and it has served me well. My only criticism is, as other's have said, the noise. Mine is mounted (like the picture attached) on a piece of Baltic birch plywood and fits nicely under a workbenc...

"Hertel" brand drill bits
I have a set of 'elderly' Hertel screw machine length drill bits, some of which are getting too short to properly sharpen. I want to replace the too-short ones and see that Enco has them on sale for quite low prices. That made me a bits suspicious, so I did some research on Hertel drill bits and fou...

Re: which type/namebrand quick change is this
Both the toolpost and the toolholders look exactly like the piston-type, which I purchased from CDCO tools. They always have the extra toolholders on-sale for a very good price. The toolholder mounted on the toolpost in your picture is what they call a "Boring, Turning and Facing" toolhold...

Re: Machining brass
Thanks once again for taking the time to give me such a detailed response, Harold. I especially liked your suggestion: "If you feel you can tackle the job with your vise, a set of soft jaws can make it easy. Make the jaws from aluminum and machine a shallow step that acts as a parallel. It can ...

Re: Machining brass
Thanks for the prompt response and suggestions, Harold. I see the logic in what you suggested and will use that technique. Midday Machining: The piece of brass that I'm starting with is 1/2"W x 3 1/4"L x 3/32" thick. Unless you may have a better suggestion, I plan on using double-stic...

Machining brass
Although I've never experienced it myself, I understand that brass can warp quite easily due to release of internal tensions during the machining process. I have some small pieces to fabricate that require a relatively close tolerance. The drawing calls for a material thickness of 2mm. I have a smal...

Re: I may have asked this before
It's pretty common in some industries to use a 'needle-point' grease gun fitting. Just as the name implies, the have a tapered (about 60 degrees) needle point fitting in place of the usual zerk coupler and are commonly available. The taper on the tip of this type fitting would seal on the hole of th...

Re: Cutting 2 st Cylinder Head Contour on Lathe
Well, that 1/2" radius revelation puts a whole different spin on the problem. I quite frequently use carbide-tipped wood router bits to cut aluminum on both the lathe and milling machine. Seems it'd be quite easy to put a 1" diameter roundnose bit in the lathe boring bar toolholder and cut...

Re: Cutting 2 st Cylinder Head Contour on Lathe
mcman56, I have no idea what kind/size of a lathe you have, but if you can securely mount the head on a faceplate, I suspect you can use a very old method that was used for cutting both convex & concave contours. You should practice a bit on a piece of scrap first as it's very important to keep ...

Re: Satin finish on steel
Tom, If the only reason you're considering this large investment is to remove rust with minimal damage to the underlying surface, I feel you're unnecessarily spending a lot of money. I would strongly suggest you do some research on electrolytic rust removal. It's inexpensive, safe and very effective...
