Removed the 6205 and 6203 from the motor shaft. Laying everything side by side to show what 20 year old bearings and belts (I can only assume these are OEM parts) look like besides new. So I have 3 new Jason Industrial UniMatch belts, a 6205 and 6203 motor shaft, then 2 more 6203’s for the yoke. May start installing tonite or weekend. I purchased them via Amazon due to the “PRIME” member 2 day shipping and Amazon credit card :)
Most important: Thank you to the helpful woodworkers who were kind enough to guide me on this endeavor. You are the ones who gave me the courage to attempt this. I received the order of the bearings last Monday afternoon and proceeded to get them installed without any major problems. I made several jigs to hold things in place while I pressed and pounded the bearings onto the shaft. Here are the bearing pads I first used. I made them to fit on either side and hold the shaft at the ex...
PTL! The bearing is finally off! I eventually came to the realization that I should remove the motor to make the remaining parts easier to maneuver. I removed all the bearing beads with no difficulty since the raceway was broken and I had already removed it. To try to keep the shaft centered so that there would be minimal torque on the opposite bearing, I wedged in a small piece of wood. On the underside of the cast housing, there is an indention (that was, no doubt, the only w...
Planer cutterhead bearing replacement #1: HELP! Can anyone give me advice on replacing bearings on my planer cutterhead?
Last week my planer blew a bearing on the cutterhead. It is a NuMark 12” planer, more than 30 years old. The company went out of business many years ago. I cannot determine how to remove the cutterhead. Here’s the issue:1. The cutterhead casting is a single unit. 2. The bearings on either end are smaller than the cutterhead circumference so the cutterhead cannot be pulled out either end. .3. From the parts schematic, the cutterhead appears to be one piece (no smaller diameter inside sh...
Parallel guide chain mechanism To make the chain mechanism, I used #35 chain and the sprockets are 10T with a 3/8 center. The chain is attached using two chain links. I had to do some metal working to create a few items: the brackets to hold the sprockets and a way of securing the chain at both ends. I had a 1.5” rectangular steel tube in my scrap collection so I used an angle grinder with a cutoff wheel to make both brackets that hold the sprockets with 3/8 bolts. Big box store ang...
Screw assembly The face vise screw mechanism is all DIY. Here are the piece parts. The hand-wheel has been kicking around my basement for 15 years. I remember buying it on Ebay for a project I never completed. It was too nice to throw away, so it waited and waited until now to find a purpose. The acme screw and nut I picked up on Ebay more recently. I cut the screw to length and drilled the hole that holds the hand-wheel setscrew. I found a 5 inch brass plate 1/2 inch thick also on...
Top Assembly The top consist of two sub-assemblies: The lower half and the upper. The lower half is made up of two plywood sheets glued together, edged with maple and joined using doweled bridle joints. The doubled up plywood is attached to the frame using a basic butt joint strengthened with 3/8” dowels and glued down with epoxy. I used this method because my wood was not wide enough for the desired final dimensions if I rabbeted in the panel. This simple butt joint gave me some a...
Leg Assembly Two leg assemblies are part of the support system for the bench. I was going to use glued up 2×4s, but found some 12/4 poplar, so sawed that to shape instead. The legs are 2.75” thick and 4” wide, and the top rail is 2.75” square. The legs are angled at about 15 degrees. The 2×4 approach would have simplified cutting the angled slots, but then you have the hassle of cleaning up the glued up legs. The large hunks of wood making up the legs give them a nice soli...
So I decided I needed to finally build a real woodworking bench for my new workspace. I got all the books by Chris Schwarz, checked all the back issues of woodworking mags and browsed the internet in preparation. Then the first thing I did was break one of Chris Schwarz rules. I decided to design my own rather then duplicate a historical bench. I think I had valid reasons. My workspace is small. I could not fit a long bench. A short bench means planning forces have a bigger impact, so I d...
It took me quite some time to get 240v ran to the basement, but the installation of a new gas stove right above me in the kitchen could not have been better timed. So, I extended the line from the stove and added two new outlets in the ceiling of my shop. I did not want to invest too much money into a lemon, so I hesitantly hooked it up to the new wiring. It cranked up and ran very loudly with no blade. Which brings me to bearings. Here is a pic of the old upper wheel bearings. They were...
