My aunt asked me if I could make some bed risers for my uncle as it is hard for him to get out of bed.
Never making anything like this before, i started looking around on google and found some instructions on making them, but it calls for a 3 inch spade bit.
I can’t seem to find them anywhere and the local home depot insists that they do not exist.
Does anyone happen to know where I can purchase one?

Thank you in advance

Thank you both very much. I agree that it seems huge but that is what the instructions call for. I am going to place the order from amazon as I don’t have any chisels either (I am just starting out)

Dennis, a question of ignorance if you don’t mind?
What are the advantages of the Forstner bit over the spade bit?

Use caution if you choose the self-feeding bit as pictured in above link….you can’t just stop it like a regular bit due to the screw type point on it.
I would use a Forstner bit in a drill press if you have to have a perfectly round hole.

Why not just cut a block to the correct height and then enclose the block with a wood of your choice to surround the bed leg ? E-Z P-Z

I personally think a 3” spade bit will break your arm (and ruin your drill) unless you go very slowly and “chip” away at it. forstner is more $$$ and the same concept other than it’s round (rather than flat like a spade bit) and will “hog” a hole faster. both leave a relatively flat bottom at the end of the hole.

without seeing your plans, is the purpose solely to get a socket into a recess to tighten a lag bolt? if so, 3” is a lot.

the spade bit is $33.00 and the risers are$20.00 a set of 4. Making them seems a little counter productive.

I personally wouldn’t touch that with a drill. Chucked in a lathe with a four jaw chuck or a mortising bit in a plunge router with a template would be better options.

I also see from your projects that you have a bandsaw. Do it like a bandsaw box.

Walmart has a set of 4 plastic ones for less than $15.
I use them and they are holding up well after several years.

How big are the feet on your uncle’s bed?

You don’t have to make the holes much bigger than the actual
feet on the bed itself. The commercial product is a one-size-fits-all,
which is why the holes are 3”.

Regardless, drilling a hole for the bed foot is far from the only
way to make the riser and bed stay in place. All you need to do
is capture the foot so it doesn’t slide off the riser, which is
easily done with a bit of trim and some nails.

I suspect the ehow was written by somebody who has never
followed his or her own directions and probably isn’t even a
competent woodworker.

I would also say just buy them unless you think you are going to need that bit again.

I would think a 3” spade bit would be dangerous and also have a short life. I can’t imagine that thing spinning wood around if it slipped out of a clamp. My friend just got his thumb working again after a couple of months in bandages. Think about this before you buy this thing.

Ok, so I just talked to my aunt and as it turns out, it isn’t for his bed, it is for his chair.
I am having my aunt measure the legs so that it will fit them perfectly.
My main concern now is stability.

I know these can be purchased cheaply from the store, but I am more interested in gaining the experience with these different types of projects.

I was also thinking the hole size was for a one size fits all type of deal but didn’t know for sure.
I may even throw some wood on the lathe and turn them instead (so they aren’t so bulky looking)

After I get the dimensions and get them made, I will post pictures.
Thank you all for the great feedback.
I truly appreciate it!

I use ones like Loren showed for my log furniture. I use my hand brace to turn it. These cutters do cut well, 4 holes shouldn’t be a big deal. (Depending what you are cutting.) You can find and old bit tlike this at flea markets or yard sales. CHEAP. These can be sharpened.

There are so many other projects and tools you will get more use from . I agree with those that say a 3” spade bit is trouble particularly someone with out experience. If you insist on using the 3” spade bit please post photos of you injuries so others won’t make the same mistake. I hope no matter how you do this that you are not hurt.
