I am assuming you are referring to Temperature Derating. Temperature derating has to do with conduit fill as well as ambient temperature in the installation area. The higher the temps the lower the ampacity of the conductors. Typically it is used in hot boiler room type installations...

With 150 foot run and aprox 36 amps you would need to run #6 copper cable to have a voltage drop of less than 3%. 1 conductors per phase utilizing a #6 Copper conductor will limit the voltage drop to 1.99% or less when supplying 36.0 amps for 150 feet on a 240 volt system. For Engineering...

Mine is heated and I keep it at 50. I have some water pipes running through it for the Master Bath above.

My attached garage is kept at 55 degrees with a Modine hanging hydronic heater. I installed a fourth zone on my oil burner to the garage. Warm enough for me to work in the garage while wearing a sweatshirt. Better than unheated on a day like yesterday when it was 8 degrees outside with high...

Paint is finished, minus the hood and table. I will do those after the rest is assembled. Here is a picture of the base. I hope to start assembly tomorrow. Sent from my iPhone using Tapatalk

Made a littlel more progress yesterday. One coat of paint on the base and head. Another day of paint and drying and then full reassembly can start. I am hoping to get this done this week.

More progress today. Actually started reassembly. Motor attached to its mount and ready to slide onto the head. Both the upper and lower spindles have their bearings installed. The quill is ready to go in. Table column and lift clamp assembled. Tomorrow I can paint the base and head. Hopefully I...

RJ, Thanks for the info. The lathe carriage came out great. I guess I have some hand work in my future.

6PT, I got the motor working properly. The switch was not closing. All is well now. Thanks for the info though. Made some more progress on the press. Almost all the hardware is cleaned and ready to go. Everything is painted minus the table, base and head. I got head and bas stripped and...

I put the motor back together this morning. Just waiting on the cap cover and electrical connections box to dry. I tested the motor and she runs smooth and quiet. I did not use the Ace Machinery Gray. I used Rustoleum High Performance Professional Enamel in Dark Machine Gray and Black. I...

Started working on the motor this evening. I wire wheeled the housing and end bells. Then I used a scotch brite pad over the entire surface and any places the wire wheel could not get. I primed all the pieces with a rust reformer primer, after masking and wiping them down with mineral...

Thanks guys. I think I am going to wire wheel any rust spots and any loose paint. Then spot prime any rusty spots with rusty primer. Prime the rest and just paint it. Should be good enough. I am not looking for museum quality here and I do not need to strip it down to complete bare metal...

How much hydrogen gas is produced during electrolysis? I was planning on electrolysis for all the parts of the press to eliminate any rust. There is not much, just some surface rust in some spots. But winter has blown in and it is too cold outside now. Can I do it in my attached garage or...

My mistake. 100 not 150. And it is a floor model. Still only a 15. LOL

Motor works. The centrifugal switch was not closing. I bent it back so it makes contact when the end bell is installed. The motor fired right up! Sweet. When it rains it pours. Last week I was looking at a Craftsman 100 from 1968. The seller stopped communicating all of a sudden. After a...

Thanks. I pulled the bearings. There was some old burnt oil between the lower spindle and the spacer between the bearings. It stunk. The two on the lower spindle had the numbers facing each other so I could not see them. Based on them being marked 6203z and the explanation about the...

I found this on OWWM http://wiki.vintagemachinery.org/ReplacementBearingList.ashx#BH_Drill_Press_10 [Delta 17" Drill Press¶ Lower Spindle (Inside Quill) - 87503 (x2) (Early Production) or 6203 (x2) (Late Production) Upper Spindle Top Bearing - 487503 includes installed snap ring around OD...

Having some trouble finding the proper bearing numbers to order. I have the parts diagram with the two bearings in the upper spindle listed. Not having any luck finding a definitive cross reference for them. Also the bearings on the lower spindle are not listed in the parts diagram and I do...

Thanks once again Dave. This thing is way more than I need but I wanted a floor drill press as I was tired of messing with the little bench top model I had. I drill holes in wood more than I do metal. Except the pas few weeks as I was building my 2x72 belt grinder. And I have never driller a...

Thanks Dave. I will check the start windings when I get a chance. If I go with a 3ph and VFD I am guessing the motor should be a 3450rpm motor and not a 1750? I got everything apart except for the post from the base, soaking in penetrant, and the bearings on the spindles. That half moon key...
