Homemade surface grinder

**turntable** · Nov 12, 2015, 09:02 PM

Hi guys; here is my homemade surface grinder. made from Makita chop saw. works very well. in the pic was setting up to grind one of those so called precision machined angle plates from across the pond. it was off on all sides as much as .008. after grinding it is square within 1/10. not bad for a cheap grinder. now I will lap it to perfection.

very slick idea. Where did you source the grinding wheel?

Really Nice build, Turntable!

Like the dressing rig too! Where does the air come from on the cooling line?

nice, is it hard to to set up? now you need a mag chuck

Hi Dave; The wheel was purchased from Enco, it's a regular surface grinding wheel (46H 7x1/2x1.250). Made a spacer to mate wheel to arbor.

Thanks Ed; It takes about 5 minutes to set up, Just slide the top in a 7/8 collet, hook the side arm on and square it up. already have a mag chuck, small 6x12, so far has been big enough for what I do.

Thanks PJ; The dressing fixture was made out of the hand grip of an old compound bow I found at the local land fill. yes, I'm a big scrounge. There is air and coolint supply on left of machine. can flood part, mist it or just air.

You have given me a good idea. I do not have a milling machine, but perhaps my bench drill would have the requisite rigidity and precision. Thank you.
