That may be, but the current NEC (250.32) requires "buildings or structures supplied by feeder or branch circuit to have a grounding electrode. As noted previously, there is an exception for a...

From the manufacturer? http://www.shopsmith.com/service/index.htm

By chance, I happen to see him on Rough Cuts while channel surfing. I was impressed with his obvious skill but also his honesty and lack of hype. He seems like guy you could sit down and have a...

As long as the splice is accessible and in a proper box or enclosure, it is allowed.

With an 8 foot ceiling height, T5HO may be too bright. You end up with a wide ratio of bright to dark. T8 fluorescents are probably going to be the most economical option - both initial and...

I'll drop out of lurk mode briefly... I built a basic workbench using kiln-dried Douglas Fir from the local Home Depot. Since I live in Oregon, there is no SYP framing lumber availalble. I used...

For a circuit protected by a 100 A breaker, the minimum ground wire size is #8 copper or #6 aluminum.

In addition to being a code requirement, it is really much safer to have the ground wire. This is one instance where the NEC and circuit theory are in total agreement. Nothing wrong with...

No. For a sub-panel, the feeder must include a ground conductor running from the main panel to the sub-panel. At least if you are in the USA.

FWIW, I remember as a kid of about 8 or 9 (over 50 years ago), seeing a Shopsmith demo in a Sears or Monkey Wards store. The guy gave me a little cup that he turned on the lathe and I had that cup...

I'm mostly a lurker here because I don't really know much, but I just wanted to say that for my Doug Fir workbench top (about 3.5" thick), I cut off the ends using a Craftsman handsaw my Dad bought...

Sorry - this is incorrect. Opening the motor circuit from a VFD to a motor while the motor is running can damage the VFD unless the manufacturer has specifically provided features to protect...

For what it is worth, this is what I was trying to describe originally (if this image comes through OK). I thought this might have some advantages over one longer tenon in terms of the expansion of...

Ian's summary is a good one. Regarding his point #8 - I would add that is never advisable to open up the circuit between the VFD and the motor while the motor is running - this can damage the VFD. ...

You don't mention the horsepower requirements, but if the VFD is adequately sized, it can provide 100% torque at any motor speed. Standard single-phase input (240 V) and three-phase output VFDs are...

Thanks for the responses. That's a nice looking mobile base, Salem - but tells me I have a lot to learn. Wilbur, thanks for the info and the link. Based on your experience, I think I'll go with a...

Thanks, George - I must be thinking about this wrong. I was considering making two 2" tall tenons, one above the other instead of one 5" tall tenon in the stretcher. But I was only worried about...

My limited understanding is that each of two smaller tenons will have less movement than one longer tenon -each less than half, so the impact on each mortise is reduced. Although I suspect with the...

For my workbench build, my legs and stretchers will both be about 5" x 2.75" (Douglas Fir). So I'm wondering if a 5" long (by maybe 1") tenon will cause issues due to expansion and contraction in...

If you are thinking about the C. Schwarz Handplane Essentials book, be advised that it is basically a collection of magazine articles. After waiting for a couple of months while it was back-ordered,...

Thanks for the responses. Yes, I have the large Jorgensen (10") vise. The 16" clearance is probably conservative. I figured to add a wooden jaw, but let in the back portion of the vise into the...

I'm slowing building up a workbench top and building up a lot of hand planing practice hours. But I have a couple of question regarding design of the base.

I plan to use a Jorgensen quick-release...

FWIW, the National Electrical Code shows the full load amps for a 230 V 5 hp motor as 28 A. Per the NEC, the feeder to the motor should be sized at least 125% of the motor full load amps. That...

I've used it - it works fine if you are able to get a clamp on it. I think the main advantage of the larger units is convenience and speed. I've always used the Kreg screws.

I'm mostly a lurker here, but I wanted to make a comment based on my present project of building a glued-up workbench top of framing lumber using only hand planes. I'm doing this because I don't...
