I need educating on.......

[jmbfestool]

.... No not with spelling and grammar.

I want to build a drilling machine for workshop.

I want it to be able to do pocket holes but then also do do square on holes.    

I know how I want to achieve this part!  What I don't know much about is pneumatic clamps and self feeding units.

So things like air regulators, switches etc.

Now I'm looking at buying something like this a self feeding unit.

Ready made complete unit this will allow me to easily make something for it to fix to.

Ill be making a bench which will allow a self feeding drill unit to adjust up and down and angle.   So it will below the unit at an angle to do pocket holes and then come up above the work bench and it will be adjusted square to drill into a timber edge/sheet material square on.

You sure about that? [wink] [big grin]

LoL well I got 1 out of the 3 correct!  lol

What I should of said. No I don't want my JMBspeak educating

 

[jimbouk]

Jmb cant you do it on the cnc?

Ironically I think Festo would be the ultimate source of pneumatic clamping systems and parts.

I don't know a lot about this sort of stuff other than there is A LOT to learn and playing with and testing this stuff can reduce the 10 count your hands offer you today!

I could with the pocket holes but having lots of small pieces  of different sizes would make it impractical I think.

As for the edge drill the Cnc would not be able to because of the nature of a Cnc not being able to get to an edge of a board once cut.

So having a dedicated machine which will do holes SQUARE to an edge and able to do pocket holes would be better I think

A gimble/trunion that allows the approximately 260 degree range you need to get from a pocket hole underneath to perpendicular above (assuming you want to have the fence in the same relative position) would be tricky to make. It would be much simpler and to make fixed mounts at those two positions and pull the drill unit out and re-attach.

 

[Michael Kellough]

I forgot you have the CNC system. With CNC, making a suitable trunion-like mounting system is a lot more feasible.

Look at the early pictures that very talented Russian woodworker posted here. He has made some rigs for moving a router along a large arc that should give you some good ideas.

I totally agree.  

Ill do what's easiest.   If it's easier to have two fixing positions then so be it.

I have no need for anything inbetween or past.  

I just don't want two machines clogging up my workshop and I want to reduce cost just spending on one machine which can do both.   It would be simple mater of rotating the fence round depending which mode you would be using.

I was thinking of making it all out of plywood just for prototype on Cnc but then change parts to alluminium to make more solid.

Just my problem is I don't know much about the pneumatic system.

I would want a foot pedal so that once pressed the air powered toggle clamp attached to the fence clamps down then soon after the drill comes in to do its job .

I haven't got a big compressor so I was thinking I would just use the air for clamping and moving of the drill back and forth and a electric motor to power the drill.

I would have it so the drill would be on constant  not bothered if it stop started after every plunge.

In the old days the moto I worked by was, "Make it prefect, or make it adjustable".

There wasn't any CNC so making it perfect was near impossible so I always design in some adjustability.

I don't know enough about pneumatics to specify parts but I do know that the amount of air you need for this purpose is very small compared to the delivery capability of even modest air compressors.

To make your system neater, less dependent on equipment you might want to use elsewhere, you could get a very small very quiet dental compressor like those Jen Air makes. I'm not sure if the smallest ones (no air tank and smaller than a Sys 1) deliver enough air fast enough but you would only need to add a very small air reservoir (the size of a coffee mug) to operate small pistons.

Check out .Rexroth, the place that stocks "Bosch basic mechanical components". They know and stock pneumatics designed to work with the T-slot rails.

I already have a compressor was planning on having it in Cnc area closed of.  Cnc needs compressor any way.

I'll check that site out thanks.

This sounds like a cool idea. I want to make a pnumatic clamping system to hold boards to a bench so i can use my boring machine for hinges and shelf holes better. Would be sweet to do pocket holes as well.

 

[Davej]

If you're only drilling small stuff would it be possible to make the table adjustable rather than the drill. Just a thought from the deep dark place between my ears  .

Ummm not bad idea I see what you are saying.

I would still need to adjust the drill from angled to square but I wouldn't have to lift up to come above the table.  Instead I could lower the top to expose the drill above the table. 

Ummm I'll have a good think about it

I posted two same picture hopefully one will be the right way up.  Some reason iphone pictures go all funny.

Hopefully my quick sketch up I just did gives people more of an idea what I'm looking at making.

The fence has a hole/ slot so when in edge drilling mode the fence is rotated round and the drill comes threw

[jmbfestool]

I know its difficult to see but I did draw a dotted line version of te drill raised up. 

I know my drawing is rubbish but hey.  Just a sketch don't want to waist time doing a more detailed one yet untill I know where I am going with this
