Delta Jointer restoration project.

Everyone who works wood needs a jointer, for squaring wood and prepping it before it hits the thickness planer. As per usual these days, most of the best quality things were manufactured almost a generation ago. This is especially true with power tools, and jointers are no exception. A lot of the ones today arent so bad, and this long bed 6" is a decent machine, but with the sheet steel cabinet, noisy bearings and castings with lots of slag still left in its not very inspiring, so down the road it went.

Nice long beds, and enough power but without that kool vintage look to go with the rest of the shop. 

One of these 1940s-50s Delta models with the kool art deco base would be great one day, but with unrestored examples going for $500+, we landed a similar era machine with the open stand for a fraction of the price, and after restoration the performance will be the same. 

A nice Delta Milwaukee short bed unit showed up, with the original welded open base stand. The lengths of wood needing to be trued doesnt require long beds, and being more compact it wont take up a lot of room in the shop. Serial number starts with 64-, so machine was built in 1948. Not many tools made today will still be around 66 years later, nor able to be restored. 

Nice heavy, webbed fence, balanced pulley and heavy cast base. 

Some nice touches include the deco wing nuts to hold the beds after adjusting, and adjustment knobs. This machine came out of a steel company and still wears its brass inventory number tag, no doubt sold off in an asset auction or just taken out of the production area. Some research into the company will likely tell the tale. 

Tables still move nicely and are tight, and once stripped, cleaned and lubed will perform nicely. 

Open steel stand with double bent feet, with mitred welded corners on the top frame. 

An add on , this switch gives a clue as to the original industrial use this machine saw, as its a heavy duty with lockout capabilities. 

The motor likely gave up years ago, as this is a Simpsons Sears pump motor that has been repurposed to drive this unit. In the scrap heap now, it will get a new motor and pulleys geared to the correct speed. 

Now to dismantle, clean and strip, rebearing , paint and reassemle the entire unit. A nice warm up for the General bandsaw to follow....

Most useful tool of the day

An impact driver is indispensable for dismantling or assembling screws in metal equipment, whether steel or aluminum, especially if they are a regular slot head. Set for tightening or loosening, when struck with a hammer they turn during impact, keeping the driver from turning out of the head. The forerunner of todays impact driver screw guns.

Next is blast, prime and paint.  Need to source bearings, blades and a belt....
