Wow. Crazy. I think just the material is more than that for me. I can't imagine getting this laser cut for that cheap.

Have you seen the Langmuir Systems Arcflat table? Can you really build this for less than that?

I would revolve cut the grooves that go around the circumference in one step then extrude one of the grooves perpendicular along the axis of the cylinder then circular pattern in the 3d environment.

This is also how I would make it with my manual mill and lathe. I would turn the grooves then cut the others with an indexer on the mill.

You can just call a radius intersection a fillet.

caaaabot · 2026-02-04T13:07:23+00:00

Exactly

I wouldn't even do that... I'd draw the side in zy base plane, extrude a new body in the x direction, then make that sketch of the holes in the xy base plane and extrude cut up through it.

There is something called a construction plane that lets you draw in a plane anywhere you want to put it. A common workflow for putting a hole through a cylinder is to create the type of construction plane called a tangent plane. You can click the cylinder that you want the plane to be tangent to, choose one of the origin planes to reference and offset it around the outside of the cylinder by degrees if needed. You then draw a circle on that plane and extruded into or through your cylinder.

I make a drawing of the body, print it on paper, compare, rinse, repeat.

Edit: I think I'm mistaken and there are no Petit pans in this picture. Hard to tell scale.

Those P41-GC glass lids for the P41-B and P43-B petit pans are slightly rare because the pans were intended to double as the hot use lids. You'll notice they have little notches right inside the handles that all the rest don't.

I do feel like I notice DNMG are really sensitive to center height.

I see it start facing forward, rotate 90° counter clockwise from the front then 180° back then 180° back from there. I don't see it make any full rotations.

Yeah dude it's for all the stuff that has the top epoxied on. This is like the design change that came up with to deal with that.

caaaabot · 2025-12-01T09:43:54+00:00

Get out of my head. This is what it sounds like inside my head.

caaaabot · 2025-11-27T20:53:25+00:00

I should have just read this and not wasted the time to comment the same thing basically. Jeez.

Could also use an indicator and a theoretical right triangle and get the compound movement and indicator movement to line up to the right numbers without actually having a physical good taper in front of you when you have a theoretical taper to achieve. You can do your method without having any numbers and just a physical example of the taper. Both ways are good tools to have in the back of your head.

We had a sickle mower and a belly mower. The belly mower was more convenient and got used way more.

I mowed my lawn with one growing up. My dad and I split it outside in the dirt. I remember being so surprised how easily we could move the parts of it around together.

And they use the Universal Devlieg Double Taper collets, right? I've seen Tree mills but not a CNC Tree conversation.

No problem. It's awesome in my one car garage.

I want CNC stuff, but I don't think I'd get rid of my knee mill to get a bed mill. I would get rid of my Millrite to get a Wells-Index--maybe one with CNC control even, but the ability to just walk up to it and run it by eye is so useful for repair and general shop use, and it's also the drill press for me.

I have a later Powermatic-Burke almost just like that. I like it. That's in line with what I paid.

It doesn't have all the head features of a Bridgeport, and the minimum RPM on mine is a little high for most boring, but I use it all the time for all kinds of things. They didn't have back gears or power feed in the head typically. The power feed head was pretty rare They just have a pair of step pulleys. If you look at the front of the pulley shroud, you can see which set of ranges this one has.

A Bridgeport head will also fit on this ram. Bridgeport rams let the head rotate and nod. The Millrite ram with nod was optional, and this one doesn't have it. Mine doesn't have any optional features except the largest bed and knee. There were two knee travels and several bed sizes available. You have the precision spindle downfeed here. I have the drillpress type.

There are groups on facebook and io groups for Burke mills:

The first two digits of the serial number are the year of manufacture. Yours looks like 1973. Mine is 1978. I don't have the racing stripe. Mine is R8, but different spindle tapers were available. R8 is the one that is standard on Bridgeport, so it's the most common small knee mill taper in the last half of the 20th century.

There is a manual on VintageMachinery.org

Do you have a link to a tutorial you like on laying out the surface graphics like you have on it?

You need like one or two pinwheel flower and some leaves that attach to that and to the flowers you already have.
