Mark, the way automotive machinists keep chips from falling into engines is to pack the drill bit with grease before drilling. The chips then stick to the bit and can be easily extracted.

This is a question for your electrical inspector...

I would think that mine wouldn't have a problem with a loop of Romex above the box, as long as it was well secured to the building (with zip...

I wasn't suggesting Mark roll his own solar water heater -- there are many manufacturers selling engineered solutions.

Why would you take all of the sun's energy, convert it to electricity (at 25% efficiency, if you're lucky), and then convert that energy back into heat for water?

For a lot less money, you could...

If you have a friend with a metal lathe, these would be as easy as it gets to make.

Take 2-1/2" bar stock, drill 19/32 hole, ream to 5/8, and part off various thicknesses.

By far the best reviews are AvE (formerly arduinovsevil) on youtube.

He's an experienced engineer with nothing to sell who buys tools, tears them apart, and describes the engineering decisions...

And since a picture is worth a thousand words, here's a picture of my clamp rack board with many hundreds of pounds of clamps on it. It is secured to the wall with 6 1/4" toggle bolts.

You guys are way overthinking this...

I mounted 4x8 sheets of 3/4" CDX plywood to my concrete block walls. On one of these sheets, I used 6 or 8 Tapcons, which will EACH support over 500 lbs of...

Andrew,
I ran downstairs and measured both my table saw spindle and a Forrest WWII.

The spindle has been precision ground to exactly .6243, and the blade has been bored to .6250, give or take a...

I agree with the above -- any competent machinist should be able to bore a saw blade to within .001" total runout, and you would never be able to tell that amount of runout on a table saw.

If I...

As long as you don't get water directly on the fence, MDF would be the better choice. It's dead flat, and stays that way through temperature and humidity swings.

Are you covering the MDF with...

My 20" Clausing weighs about 700 lbs, and it is definitely not considered large in machining circles. Radial drill presses can easily be multiple tons, and knee mills start at 2000 lbs.

I don't...

I say neither -- find another 3 phase motor and build a cheap phase converter. I have less than $100 into mine, including switches, relays, capacitors, and the motor.

Very few woodworking...

+1 for drilling a hole in the back of the chuck and pressing the arbor out. Chucks backs are intentionally left unhardened so you can do this.

Alternatively, while you have the chuck and arbor...

In addition to my gantry crane, I have an engine crane. It's awkward and unwieldy and takes up a huge amount of room, so I almost never use it if I can avoid it.

A friend borrowed it a year ago,...

Wow, I'm seeing a lot of advice here that would kill someone if anything goes wrong.

I have a small milling machine... it weighs 2500 lbs. When I bought it, the riggers set it in my garage on...

Any auto store should have GL-4 gear oil, and that's what I use for all machinery gearboxes. More common gear oils are GL-5, and they can corrode brass or bronze gears.

I have a pretty complete...

You could use 2x4s with screws partially driven in. A taut stringline, sighting down them all, or a long flat level will help you get them all in the same plane.

This part of the spindle just keeps the parts centered, doesn't it? All the force to the cutters should be transferred through the bottom and the nut on top.

I would probably turn an oversized...

I think any 88505 bearing will work that has metal shields or rubber seals. Be cautious of new old stock... the grease inside the bearing may no longer be good (sealed bearings have about a 10 year...

It's a device that measures temperatures of objects at a distance from infrared radiation. I have this one from Harbor Freight:...

Yeah, the bearings you have should have metal shields with felt seals on the inside. The grease inside them is well past its expected life, so you should replace them.

I generally replace sealed...

Any 88505 bearings should work. A wood lathe isn't a super critical application, so I would get some cheap ones from an auto parts store. They'll probably give you ones with rubber seals, instead...

The manual shows that your lathe uses ND 88505 bearings, and of course, New Departure hasn't been around for decades.

You're fortunate in this case, however -- 88505 bearings seem to be a fairly...

If the outboard bearing has shims behind it, a good starting point for preload would be to reuse those shims and see what you get.

Spindle bearings in machine tools are usually preloaded such that...
