Your tank looks a Nice Big one ?, Is it alloy. Cheers bill.
Yes, it is an alloy tank. I think it is maybe over 4 gallons.Your tank looks a Nice Big one ?, Is it alloy. Cheers bill.
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.

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?
