I’m sure this has been brought up before but I’m considering converting my hand planer to use a a jointer for small projects. I have the new Bosch model and it has 2 spots on each side to connect the guide. I figure that this would be good to firmly attach it to a frame which would attach to my bench. Because having a blade spinning at 16,000 rpm by my fingers is REALLY scary…I’d want a cover for the unused part of the blade. Is there any specific kind of wood to use to make the frame? I see a lot of stuff that’s made of plywood and was wondering what kind people recommend.

Sorry. I can’t even understand what your issue is.
Pics, diagrams?

You can buy a table-top jointer for a couple hundred bucks. I’d go that way. Or use your hand planer as it is intended, just clamp the wood down rather than the planer. That would be easier.

However, you would not be the first to attempt this. Turning a hand plane upside down (the human powered type), clamped in a bench vise, to use as a jointer is a common practice. While the blade is exposed, it ain’t spinning at 10k rpm!

If you go down the path with your power planer, be careful. Consider what might happen if the unit came loose from the table in the middle of a cut.

Bill, Starfury is trying to do this: http://lumberjocks.com/projects/45954

Starfury, not sure I can answer your specific question about wood except to voice an opinion that plywood is probably fine.

What I do want to point you to, to give some ideas, is the way that a planer gets attached to a Triton Workcentre to turn it into a jointer. The novel idea with what they do is that the planer is on its side and the blades are vertical, so the wood lies flat on the table. Their picture shows a fence being used to control the wood safely, but a featherboard could be used just as easily in which case push-sticks could be used to move the wood. Chances are that you could design the whole thing to lie on top of your workbench to secure the planer so that you need not be as worried about it dropping out and causing trouble.

Final comment though. When using machines, the general trick that I have found is to move the wood on a stationary machine when the wood is small (within limits) and to move a hand-held machine when the wood is large. Jointers are an exception because jointing small pieces of wood is exceptionally dangerous. So as Sawdustdad suggests, there is a strong case for just clamping the wood and using the planer as intended.

Hope this helps.

Tootles..that is exactly what I want to do. Cost is an issue plus space in the garage too. I don’t plan (at this time) needing to join large pieces of wood and if I do get to that stage where I’m doing a lot of work then I’ll invest in one.

If you like doing stuff like this OK, but if you’re looking to save money I agree with poster re: find a small 4” benchtop jointer for a hundred bucks.

Time/Effort not worth it unless you just like doing stuff like that.
Me, I rather buy machine and get to ww’ing.

All said, you’re probably just as well to grab a 7 or 8 jointer plane if one comes up.

NOW I know.
I tried that once years ago. Still have all the fingers, but it scared the crap outta me.
You can get a Cutech 6” bench top jointer for under $300.00 + shipping. Great small job jointer. I have one, and use it often. It has the helical head. Check it out.
I am not associated with Cutech. Just a happy owner.
