Hi all, The marine 2 part paints are very good re finish and durability, however many of them are not for amateur use. You can get them from marine suppliers, but they don't encourage sales to DIY folk. Many of the best two part marine topside paints are LPU (Linear Polyurethane). LPU paints

Re: [Emc-users] Durable Paint [Was: gee, is list in anechoic chamber]

Usually when they put "marine" on the label the price automatically gets jacked up 50%. :-( Two part poly/urethane paint is great stuff, but it is also very toxic. Isocyanates are usually used as a catalyst. You need to be very careful with that stuff. I have used it, and it works great,

Thanks all, I'll swap the X drive onto the Z motor in the morning and do that test. The drive is a Bosch Z15-1A-240 - which is a thyristor drive. I'll pull the output pack and see if I can find any identifying marks on the thyristors. Thanks Ben -Original Message- From: Gene Heskett

Re: [Emc-users] Durable Paint [Was: gee, is list in anechoic chamber]

Gene, Do you live anyplace near a large body of water. If so there is a West Marine store near you. Look for the paint there. They sell stuff used by boat owners who keep their boat in salt water 24x7. The best paint I found there is a catalyzed two part polyurethane. It comes in two cans.

Re: [Emc-users] Bridgeport servo troubleshooting

Your testing technique is good. I don't know the particular servos that you have, but on my BP, the servos have a tach feedback. Since the runaway condition happened on 2 different motors but the same drive, either the input from the tach feedback may be bad, or you've got a output device

Re: [Emc-users] Bridgeport servo troubleshooting

I would try putting the X drive connected to the Z motor in place of the Z drive. If it runs fine then you know that the servo motor, tach, encoder, and wiring into and out of the drive are all fine for the Z axis and thus the drive would have to be the problem. On 03/04/2017 11:37 AM, Ben

Good afternoon, I've got a converted Bridgeport Interact which decided to give up the ghost last week. I think that one of the servo drives/amps is dead, and am hoping that someone can sanity check my troubleshooting before I start spending money. Before I removed any wires, I checked the

Re: [Emc-users] Durable Paint [Was: gee, is list in anechoic chamber]

I have a friend that lives in Frankfort, west of Traverse City, MI. He got 8 inches ... which is very common up there. You have had it easy this winter. I'm 200 miles south and I was getting used to 60 degrees in February! :-) I started my snowblower in November and ran it once in December
