Replacement parts for Central Machinery 8" bench grinder item #39798
Depends what parts are needed. Spare parts for something that goes wrong so rarely can be difficult especially if the machine is imported.
Some parts will be fairly universal and so fairly easy to obtain - nuts, flanges, abrasive wheels, bearings, capacitor (if fitted) and possibly even the switch and tool rests.
Jonsered 2149 turbo , does any one know the factory settings fornthe carb ? Iv turned the H L in all the way waiting instructions , what about the idle ? Thanx
Yes I do. Do not over tighten the H and L needles you will ruin the needle seats (clockwise closes the needle jet, counter clockwise opens the needle jet) There is no air mixture needle on a chainsaw carb (2 cycle engine) all are gas mixture needles H - high speed operation, L - low speed operation. [The saw carburetor operates like a 4 barrel carb on a 350 chevy, runs on 2 but kicks in all 4 when you hammer it.] Turn the H needle to 1(one) full turn open (counter clockwise). Turn the L needle to 1 1/4 (one and one quarter) turn open (counter clockwise). NEVER EVER close the H needle to less than 3/4 open or the L needle to less than 1 turn open. If you do you will burn the saw up from lack of oil lubrication. [I have several Jonsereds saws a 52E, 451EV, 49SP, 520SP, 621 race saw, 630, 70E, 70E race saw, 80E and last but not least a 90E. I worked many years for the importer and distributor of Jonsereds as a Territorial Rep. All my saws run like a top. My newest saw is a 1984. I chainsaw carve and cut firewood with all of them year round. In short I like-em, they're the best.] I find that all my saws run the best and strongest with the carb set at around 7/8 turn open on the H needle and just above 1 turn open on the L needle. The idle screw I set last after the saw responds correctly to the carb settings. I quick throttle the saw to make sure the saw picks up RPM and doesn't fade out, put in a log to make sure it maintain tourque under load and not bogg down (tweak the H & L if needed, remembering the 7/8 - 1 1/4 rule I adjust the idle screw to where the saw sound smooth and un-labored at idle. I never let it idle to where the chain moves when it idles. For safety reasons. Hope this helps. EdN
Need a new switch for buffalo grinder model B-8CB
That entire older Buffalo line of grinders: N-10CB, B-8CB, B-6CB, bgbr-6cb all use the same push pull switch. Most of those grinders were dual-voltage with a starter capacitor and there are 6 wires connected to a 4 contact switch. The "Jet BGS8-076" grinder switch that is used by the older Buffalo's, Galaxy, Duracraft and TestRite grinders is no longer available.
The good news is that there is a replacement switch from another manufacturer: "3030-9001 push pull switch for RDX grinders" from Wholesale Tool is a direct replacement. It has the same 4-screw contacts on the back and the same push-pull diamond pattern front plate.
I need an on/switch for
Find a Single Pole Single Throw (spst) toggle switch at the local hardware store rated for the load of the grinder. Wire the switch in place and viola you are done! Machines are stupid;they can tell the difference between an oem part and a replacement.

Replace missing switch on bench grinder
2 wires are not needed to use they are the wires of an supression capacitor on the switch then there are 2 wires from your power cable and 2 that goes to your motor that 4 you only you have to use you can also connect the 2 wires from the s-capacitor with te wires on the motor together thats is how its also correct, (but best is to remove it because its only for suppression for FM ukw radio signals and everybody has DAB+ and the change to have short-circuit is reduced.

I have a Buffalo B-10CB(CH)
You could connect the wires of the switch together inside and bypass the switch. Then I would connect in the power cable a switch rated for 1 hp. You can use surface mount electrical box, with two cable connectors (one for the cable going into the grinder, the other for the cable going to the male cord end of the cable. Install a 120 volt switch inside the box (similar to the light switch in the wall). Make sure that the switch is rated for 1 hp. I would install the switch under the bench, under the grinder.
