I'm assuming your plate either has a center hole or can have one for mounting. Cut a piece of masking tape exactly the circumference of the plate, and mark out the number of divisions. Apply to the perimeter of the plate and rig up a pointer. Rotate to align the pointer with a mark, hold and...

May I suggest that many of us probably have a bit of arthritis in our fingers and while we all try to catch our typos and the forum system does pretty well in flagging the obvious ones a few will get through. Some are even quite funny.

Makes you squirm just looking at it doesn't it? Stan

Using this MAY cause the polycarbonate to become brittle. Baltimore City Prison tried large clear polycarbonate windows to keep the inmates contained a long while back. The hope was the lack of bars would give a more open feeling to the pen and reduce inmate violence. If you have even spent...

800 grit paper used with soapy water, followed by 1200 grit should get rid of most of the fine scratches, a few deeper ones won't matter in this application (or at least wouldn't to me). Buffing with baking soda made into a paste with water, toothpaste, or a plastic polishing compound using a...

You may find spare parts are available in Canada from Princess Auto. They seem to be the Great White North's Harbor freight. Cheers, Stan

Tired, on the road, laptop keyboard failing. Yes, it's Toni.

You can purchase the PDF set for all the mags from Mike and Tony. Last time I looked it was $6 per back issue. Cheers, Stan

MSC at least doesn't list any 1/4-32 thread repair inserts. I think the practical repair will be as JasonB suggested, use Loctite retaining compound to secure a shop made plug.

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...
