... just a rough lash up with an old drill, and old vee belt and some odds n ends - but it works!

A bit of a (free-form) play in the third pic, and some blurry swarf just for Jo!

She's an active little tyke Tel, looks great. How are you lubricating the large bronze bush, and what sort of stroke does it have? I know how I can find this out, and so do you, but the others may wish to find out.

 ;D There's a grease nipple in the end of the crankshaft, behind the vee pulley, that sents grease to the eccentric bush and the plain main bearing. The top pin and the vertical rod are lubed by manual oiling.

Stroke is 1 1/4" - a little shorter than the original plans, but I had to modify it a bit to make the materials I had work.

Speed, as far as I can judge, at the moment is around 140 strokes per min - probably a bit far but I am waiting on a speed controller for a little 300w motor I have on hand here, when that arrives I can make up a proper drive arrangement and get it all mounted 'somewhere'. Might run the tacho on it tomorrow anyway, just as a matter of interest.

Thus far I am happy! Next, a hold down for it (not that a lifting workpiece is really a problem) but I am thinking one that will mount on either rear corner of the table, swivel and adjust in and out.

Just curious, Tel, is there a particular reason you opted for an eccentric/crank drive rather than a scotch yoke type drive?

Hey bloke, what was the winning hand :LittleDevil:. Really, great job. When you get it all anchored and geared up I'd like to see some video from under the table. I see the way it runs, I'm just gotta a little confusion on how. As a matter, kinda reminds me of myself in me younger days :lolb: :LittleDevil: :lolb:


Yo redneck,

Chuck, that's the way the AME version was drawn - I suspect because of the much great bearing surface on the eccentric.

I wish! Life would be much simpler. It's a 1/2 hp 240v 2800rpm motor, hence the need for the speed controller.

I didn't know you could control the speed of those motors electrically. Well, not cheaply or efficiently. Looking forward to hearing of the results, hoping you'll excuse the tautology.

It's one of these

The ratings look OK, so I have hopes, but I'm afraid I am a bit of a babe in the woods when it comes to electronics. Time will tell - hopefully try it tomorrow.
