Shopmade woodworking machinery #1: Shopmade oscillating spindle sander

Thanks for posting this. I’m not sure if I’ll ever get around to building one, but I do like looking at some of the ideas others come up with. I’ll be looking for part 2 and hoping it works well.

Wow that’s some great engineering ,very cool.

Very impressive design and workmanship but I’m thankful for Harbor Freight where these can be bought for $89 here as I don’t have the talent to construct one. You are doing a great job!

very cool, and a very nice build!

the oscillating strokes seem quite fast at 100spm, do you find that this is a good speed?

Thanx for the compliments guys.Wish we had HF in Norway, I see a lot of stuff there that I could use, or modify to suit my needs.

I am not sure about the stroke freq. but I assume it will be no problem. it looks sensible, but i have not done massive testing.

Not sure about your HF, but the one by me has no Oscillating spindle sander for $89. The cheapest I see them go is $130. I’m taking a (not so) wild guess here and will say that this one is constructed better than the one from HF.

Thank you it’s very nice work

and would you like please tell us more detail i need to build this machine but the photo lack explanations

please share the all individual parts separately and all steps to accumulate this machine

thanks in advanced

Thank you lolototot.

As the machine is finished and in use, I really dont want to dissasemble it to take photos of each individual part.
All the photos I have is posted in this blogs 2 pages.

There is information about the parts in the text.
All the parts are salvaged parts and is not something that is comercially available in its identical form. i just took what i had laying around in my shop.

Here are some of the specs copied and pasted from the blog text:

1: The drums are homemade from 3/4” baltic birch plywood, stacked 7 in height, glued and trued and the centerbored in a lathe.

2: A 550w motor is running this on a V-belt drive at a ratio 1:1. The motor is a 1450rpm

3: A second motor for the oscillation is a 9w geared motor producing about 100 strokes/min.
Stroke distance is 30mm (I do not remember the gear ratio)

4: Linear guiding is an old guide from 80s german edgebanding machine dissmanteled at work, and the shafts are 40mm with ballbearing bushings

5: The ballbearing blocks for the drive shaft is made from solid oak (pillowblocks or flange blocks would be better, but as mentioned, I took what i had laying around)

6: Driveshaft is 20mm diameter

7: Motor mount and baseplate are 3/4” baltic birch with plastic laminate

8: The machine cover are from the same material, and alu cornerprofiles, and an off market chineese stop/start switch

9: Top will be 30mm plastic laminated particle board with inserts to suit the diff dim drums.

10: Dust collection is a 100mm port to the enclosure underneath the spindle.

Hope this helps.

But, I had now drawing or plan for this build. Just use whatever you can get your hands on, for free, or cheap.
if you are to by these parts you propably arebetter off buying a comercial one.

Best reg

thank you very much for your fast reply

but what about the mechanism of motors,how up and down movements occur with rounded motor in the same time
i think that there is a motor joint with (up and down) and anther motor just attached to make these to movements

please explain in more details this actions

and thank you again very much sir

lolototo:
Check out this video, it shows both motors and the movements they make.
The stoke movement is only 30 mm, that is 15 above and below center of the pulleys in coplanar.
Hope this explains it for you.

Just discovered your machines through youtube and now see that you are a member here as well. I think it is no shame at all liking to build/fix/tinker with machines rather than using them. Is’nt that part of what being a man is all about?
Great inspiration. Thank you for sharing!

Well C,
I have been building cabinets and furniture since 1977 when I started in business for my self.
Now that I am retired and have a bigger shop than ever, I think I would rather build jigs and machines
to make woodworking more fun than actually using them. So I guess we are in the same boat.
I am a member of your you tube page, and have enjoyed watching you there. Glad to see you here
as well.

@kaerlighedsbamsen: You are correct, its called beeing a man:)
@todd628: I like your thinking:) We definately speak the same language, and I wish you luck on building jigs and machinery to fill up your shop. See you around, borth here and on YT

That’s some solid stuff there! Any alternative for the linear guiding? Doubtful we all have a german 80’s something or other laying around :) Definitely on my to build list! :)

can you explain how you use capacitors to run 3 phase motors on single phase power?

Thanks, Todd
