Forming the Round Doors for the Home office

Project by Lee A. Jesberger posted 867 days ago 1295 views 2 times favorited 24 comments Add to Favorites Watch

In the home office project, there are large curved door. At the time of writing about the project, the pictures showing the form work were mixed in with over a thousand other pictures.

Well, we found them, and I thought some people would like to see how it was done. To be honest I forgot how it was done, and had to ask my employee / partner. I guess old age is setting in early.

He is the same guy that introduced me to vacuum systems originally.

See: http://www.prowoodworkingtips.com/Vacuum_Systems_pg_1.html

The two layers of 3/8” bendy ply is inside the bag, already glued. The plywood is clamped at the bottom of the form, bent over the form, and then clamped at the top. The the bag is turned on and the vacuum is pulled. The green felt is inside the bag to permit the air to be pulled out of the entire length of the glued up parts. Without the felt, the bag would suck tight to the plywood, and leave air in the far end of the bag.

If this form were to be placed in the bag, it would be crushed in short order.

Add this technique to your repertoire and your woodworking can move up to another level with possibilities.

Lee, it looks like the door was made wider than needed because of the screwed board along the front bottom. I assume this was done cut it a to perfect width and fit? Thanks again Lee!

Karson, no caul needed as that’s what the vacuum bag is used for (applying lots and lots of pressure evenly across a surface) – if that’s what you meant.

To form the bendy ply had you just clamped it to that form previously?

Hi Roger,

We make them oversized to permit us to square it up later. Pieces have a tendency to slide in the glue up process. The extreme pressure and the glue cause it to move rather easily.

When made oversized, we don’t have to be overly concerned about it.

Although, even if they were made to exact size, filling the holes with bondo wouldn’t be a problem.

Hi Karson,

No cauls were needed with this process. One of the fine points of vacuum bags is there is no need for cauls.

The pressure is evenly applied.

Hi Damian,

Correct, clamp the bottom , making sure both sheets are tight to the table, bend the bendy board, clamp it at the top and turn on the vacuum.

Oh cool, I didn’t know that would work. When I said just clamp and glue I didn’t think the press was involved. I’d assumed the bag would have tried to flatten itself pulling the sheets towards a horizontal plane. Do you use felt in the bottom of the bag too then so all the air can escape or is having it just on top good enough? I’d also just like to say thanks again for all the hints, tips and how-to’s you’ve posted, I’ve already learnt a huge amount from your posts so much appreciated.

Hey Damian;

No, no need for the field on the bottom of the bendy ply. The vacuum is strong enough to pull air thru the plywood!

Thank you for the kind words. Sharing what I’ve learned is becoming one of my biggest pleasures!

A good friend friend of mine in his early seventies, was a master plasterer with skills that took a lifetime to learn.
His worst fear, which did happen, was dying before being able to share his knowledge. He was a third or fourth generation plasterer, who was absolutely incredible. I hope one day to be as good at what I do, as he was at what he did. A terrible waste!

That may have something to do with my desire to pass along what I’ve learned. And the fact that someone taught me, whether it be a book, employee,(as is often the case), or the school of hard knocks. I do have a P.H.D. from that fine institution!

When I see beautiful work processes like this, it make me feel a little foolish showing the small items that I make.

Thanks, Lee.

Don,

Some of my most favorite projects have been small items like dead blow hammers, or the cook book stands, and the like. If I can find the pictures of the dead blow hammers, I’ll post some of them. The are beautiful, and we get to use them while making other things.

They are not overwhelming like larger projects can be, take only a small amount of space, and the pride in what you made part comes along much quicker.

A work of art, is a work of art, regardless of size. (at least that’s what I tell my wife anyway) LOL

I don’t even know what to say to this, Lee. I’m looking at those pictures like a Labrador dog that you are speakin Chinese to. A head tilt and confused look. I truly look at your work with awe and wonder. As you can see, I haven’t had a chance to get on the site in a few days, so I’m just engorging myself with the amazing content that such skilled and knowledgeable people are providing here. Lee, you are upper echelon!

Hi Tom.

You just described how I look when I’m trying to figure out how to build something. But since I have boxers,
I probably look like them!

I look at the drawings and wonder, aw what did I get into this time?

Your words are too kind.

This is a great learning experience for me, as I would not known how this would be done. You are able to turn out some incredible work Lee. If you were not so far away, I might be camped out at your shop just to work there and learn.
