I like the vegetable swarf term very much! Seem the last few weeks have been almost entirely devoted to chain saws, tractor and implements, landscaping, planting, and seed starting. At least some model making is happening, but more on the train and model boat side of my hobby world. On the...

I had not seen these partial kits before. Pretty interesting. These would be great for someone at the beginning of a hobby machining interest. That's where I was around 30 years ago, decent wood worker, bought a 9 inch lathe mostly for functional repair work but also for fun. No mill, decent...

One thing that effects the use of diamond grits in the home shop is that it's a HOME shop. Many things that are accepted practice or avoided in industrial production just don't matter in our little world. I really don't care if I trash a small $20 diamond disk or wheel every two or three years...

A cnc handwheel could easily be spinning at 500 to 1000 RPM based on 100 IPM feed rates and a 5 to 10 TPI leadscrew, triple that for 300 IPM rapids. On something like a Sherline, with 20 TPI screws, a 60 IPM feed will be doing 1200 RPM. That's about the top end for rapids or feeds on this...

Adding a handled wheel to a powered lead screw does require that you check that nothing is fouling the handle before you engage and threading or powered feed activity. Sort of obvious, but I ended up taking the handles off a small CNC machine as they were more of a hassle / danger to fingers...

I have to warn you, I used to be really up on the whole CNC CAD/CAM world, but other things have taken my fancy in the last several years. Using CNC tools still matters to me, but building, tweaking, and discussing / arguing fine and subtle points of it all just doesn't excite me the way is...

Most routers aren't able to do good work in steel. The spindles are not up to the task in many cases, and the frames and beds aren't stiff enough. Accuracy and repeatability may not be sufficient for your desires. These days for this scale of work I'd be looking at buying a CNC ready Taig...

The VersaMil manual calls out a Morse taper spindle, but not the number. If you can sell the machine to some collector or person who needs the portability of the Versa Mill for enough money to buy what you want that's lovely. Otherwise, machines are just another consumable in a working shop...

Now I understand! Your post didn't quote the original, so I thought it was in response to the immediately preceding post. Sorry for my confusion.

It may just be coincidence, but having played with metric and imperial simultaneously for years whenever I see 0.004 inches I think 0.1 mm and the other way round. Any chance a measuring system conversion introduced this difference? Not knowing the engine, would a piston with a lowered pin...

Greetings, When you check enable acceleration control in Cura all the acceleration settings will be displayed. You may need to click hte hamburger (three horizontal lines) to the right of the search settings box and select expert, I rarely use Cura. In all seriousness though, you might try...

Many of the book Lindsay had republished have been scanned and are online at google books. Many can be downloaded in several formats. Just verify the book has the illustrations, many of the earlier scans seem to have only stored the text, leaving white space where an illustration or drawing...

As I get older I find a bit cleaner and more organized shop helps me get things done. Seldom get very far towards some "editor who never set foot in a working shop" idea of the perfect shop as seen in some woodworking magazine photos though. Perhaps it's the clock and watch maker background or...

Your drawing appears fine and dandy. Use LOTS of light cutting oil / kerosene / alcohol with this as you are cutting aluminum with a zero degree top rake. Poking a 1/8 inch hole before using the D bit will avoid having the zero speed center zone fighting you the entire way through the hole and...

If you are talking about the D bit style just knock them out with W1 or O1 drill rod, mill off just shy of half the diameter, harden, and then stone to a good finish. If talking about the straight flute solid carbide bits I "guess" you could fabricate one on a Quorn, Stent, or similar T&C...

A straight flute carbide 13/64 drill will be very stiff and is unlikely to wander in any noticeable amount. Pricey perhaps but if you are really bothered by this issue it's a decent solution. It will leave enough material to ream or do a fine boring pass...

It's going to be a gorgeous model!

I've dealt with disks larger than my lathe capacity by mounting them on a center shoulder bolt or a rotary table and used the mill. The only trick when using a shoulder bolt is how to turn the work while maintaining control. Obviously climb cutting is out, but somehow when a conventional cut...

Greetings! There are two distinct parts to this deal. One is getting the best print, the other is dealing with the areas that aren't good enough. Fixing surface defects / artifacts of a layer based build process (resin or FDM): I typically use auto spot putty rather than a two part material...
