where to get v-belt for drill press?

[rlim]

Hello,
I've read about belts causing excessive vibration and would like to get a new one for my HF 8" drill press (item #44506, no longer in production). However, I've searched everywhere and can't seem to find one that is this small, basically 5/16" wide and 1/4" tall. Getting a link belt is out of the question for this size. The part number in the manual lists V5, 5/16x26, and the marking on the belt reads K26 - 660. Any ideas?

The vibration is really irritating. I get the 'blur' (double image) when I turn the drill press on and look at the end of the bit. And of course the hole is bigger because of the slop. I did run the drill press without the belt and the pulley was dead on, i.e. with no play. Not sure what to look for other than wait for a sale price on a dial to check the chuck for excessive play.

Thanks,
Richard

Welcome aboard, Richard. If you have an Ace Hardware nearby, that might be a possibility. Some of them have a lot of items that others don't carry. Sears parts store might also be another possible source.

auto parts stores should have a variety of v-belts.
Other than that check ww.graingers

you need a K26 belt. it is really that easy! "K" indicates its profile, 8mm (5/16) wide and 6mm (1/4") thick, "26" indicates 26cm long.

look in the phone book for an industrial hardware supplier or bearing or hydraulic shop. they usually carry or can get a variety of belts. Motion Industries is a national chain of belt/bearing/hydraulic supply shops.

I'm not sure a belt is going to help. If the tip of the bit is not moving in a perfect circle something is very wrong. Check the bits to be sure none are bent, check the quill bearings for wear (most likely problem), check the chuck to be sure it's tight and that all 3 jaws are closing evenly.

Your chuck may be mounted with a Morse taper. If so, mark it, take it out, and go over the taper and the socket with fine emery cloth or steel wool, then put it back in with the marks lining up. If the wobble still exists, take it out again and turn it 90 degrees before re-inserting. One of those two steps could correct the wobble.

I hate to mention it, but I don't take everything for granted... One other thing it could be (if you are getting all the wobbles using the same drill bit), try another. The bit may just be bent.

Northern Tractor carrrys a huge inventory of belts. Just take your old one and match it up and don't forget the auto parts store also. Almost all tool belts can be matched at one or the other except in rare cases.

jw,

You might try one of those segmented belts. They remove the vibration caused by a flat spot or kink in your belt.

Thanks guys.

Really appreciate the suggestions. I swung by the local Ace hardware store and they only have 1/2" v-belts. It seems like 5/16" wide belts are not common. Also went to the various websites that were suggested and couldn't find one that is 5/16" wide.

I also took the chuck out and rotated it 90 degrees and it didn't help. I still think that the 'wobble' or 'blur' is due to the vibration. IOW, placing a quarter on the base will 'walk' when I turn the drill press on. Vibration due to motor running without the belt is minimal. I find it hard to imagine what can be wrong with the belt. Looks fine, feels fine, unless it's not manufactured to tight tolerances which is causing the substantial vibration.

I must add that I am running the drill press at max speed, i.e. ~3000rpm. I will try it at a lower speed when I get home and see if I get the same blur. That will tell me if it's indeed a vibration issue, won't it?

I am beginning to wonder if this drill press is a lemon. Just placed a bid on ebay for a dial indicator, so hopefully if a belt replacement doesn't do it, I can at least check runout just to rule that out.

Off to the auto store......

The link belts are amazing - DP IS running at 2,500RPM...

no beef!

Okay, I've been to Ace, Sears, and Autozone. Still no 5/16" belt. Do you guys think I should try this twist-lock v-belt from mcmaster-carr? I'm looking at part# 7881K11, which measures 3/8" Wd and 7/32" Ht. Not quite the 5/16" and 1/4", but I wonder if it'll fit......

I did a little homework for you
try any of the following, they will speak belts:

Motion Industries <----try these guys first
1314 Duff Dr
Fort Collins, CO

Grainger Industrial Supply
4531 Innovation Dr
Fort Collins, CO

Applied Industrial
1721 1st Ave
Greeley, CO

take your belt with you, K26 is the belt you need. it is not a common belt but it follows the standard industrial sizing/identification system.

I had recently changed the speed on my drill press and it started to vibrate for the first time. For some reason I loosened the belt tension a little and the vibration went away. If your belt is old (10 years) like mine, that may help.

Hello! Old news maybe, but I didn't find them anywhere else mentioned nowadays and I finally found them here: http://beltpalace.com/k26.html
I had them in a few days after I ordered. I hope that helps someone else with these odd little K26 vee belts. - Mr. Bob
