When Tony first built the engine it was fitted in a modified Featherbed frame. It was always his intetntion to put it in an Ariel frame, he just needed a suitable Ariel frame and time between other projects to get around to fitting the engine in to it.Was the engine in a featherbed at one time ?
Hole saws in bulk was very economical and worked well in ss and far less expensive than annular cutters. Especially in steep angles such as stair railings deep cut / fine tooth hole saws worked great. For softer materials I had special carbide tipped cutters made.Thanks for that. Is there some reason why you use hole saws instead of an annular cutter? I know the saws are cheaper, but thinking maybe an annular cutter would last longer? I did end up using hole saws instead of end mills because it was faster and less chatter on the poor old Taiwanese vertical mill, but the saws seem to take a beating.
Thanks. When I was dealing with my brother’s estate, I was a little overwhelmed with the contents of his shop and garage. I actually tried to sell the larger mill and considered selling the smaller one. I didn’t try that hard.. when researching the value of the Atlas, it had some pretty good write ups and apparently the one I have turns out to be one of the more desirable models, so decided to just keep it. Seldom gets used though, especially compared to the vertical mill or lathe. The previous photo was just grabbed of the net, this is mine. Currently used to display my chuck collection. The hand wheel on the front unfortunately suffered a bit during its journey across country. Now replaced with one of those alloy idlers that we normally hang on the wall for some strange reason.Hole saws in bulk was very economical and worked well in ss and far less expensive than annular cutters.

Interestingly I too have the same small Atlas horizontal mill as yours.
If you intend on using Sunnen mandrels I'll be interested to see how you solve the problem of applying pressure to the back of the wedge in order to advance it into the part being honed. I never got that far before buying an actual Sunnen hone.Any thoughts on the subject?
It is buried in the bowels of the machine, but it's a rectangular rod that has a slot in it to engage the back end of the wedge on the mandrel allowing the foot pedal to push the stones up or pull them back down. There's a spring involved as well, whose force is adjusted by the knobs on the front. That is, the slotted rod pushes on the wedge via a spring whose preload is adjusted with those knobs. The absolute position of the slotted rod is determined by another knob. You crank the knob, forcing the stones up, until the dial indicator registers the displacement of something inside the housing. As the part is honed away that displacement decreases.I was thinking of asking you what the Sunnen setup looks like, or is it buried in the bowels of the machine?
I can't tell from the photo what the black shaft at the right end of it looks like. Overall, it looks sort of like a mechanism to make a right turn, e.g. to turn your horizontal mill into a vertical one(?). But, you'll have to let me know what it is for me to tell if I have something equivalent, or if you can sleep like a baby tonight knowing you have something I don't have (but, which I clearly would then need to find...).IOn another note... So can I remain feeling smug, or do you have the device or a reasonable facsimile of the one in the second photo?
I'd feel worse about ruining your sleep tonight, but it's your fault I had to get up from the sofa and walk out to the garage to take a photo of my Tapmatic 50X. However, mine only covers the range from a #6 screw to a 1/2" bolt so I suppose if yours does a 4-40 or 5/8" you have me beat and you can sleep well.used for driving taps. Pull down on the drill press quill ( handle) and the tap threads the hole. Pull up on the quill and the tap reverses out of the hole.
Cyborg and I may have temporarily digressed/transgressed, but the last couple of posts were the result of a conversation he and I were having on another forum about honing roller bearing races to change their clearance, a subject of direct interest to this mongrel thread. He's rightfully jealous I have my own Sunnen hone, but I'm jealous he has his Comet so far along.Cyborg started this thread as Comet-Mongrel.
Time to create a new thread for your "Tool Talk" guys.
Nice post, my comment was not meant as a slap on the wrist, a gentle reminder that original thread is "Comet Mongrel". Like any conversation at a club night or in a pub, conversations can stray off-piste. (Guilty myself. )Cyborg and I may have temporarily digressed/transgressed, but the last couple of posts were the result of a conversation he and I were having on another forum about honing roller bearing races to change their clearance, a subject of direct interest to this mongrel thread.

But, we shortly would have returned to discussing honing of bearings and bushes for Comets (and other Vincents). But, speaking of digressions, somehow Ariels entered this thread without incurring anyone's wrath, so I think Cyborg should be cut a little slack on the content, especially since it's his thread, after all. It's hard to imagine any thread going for 29 pages without an innocent digression or two.
But, I digress...
