  1. The under glaze is done on the bisque fired plates of plainsman m340 clay then the dip in the glaze after it has dried.The clear glaze is the plainsman premade glaze mix just add water.
  2. Using PSH under glaze. This has been doing it for awhile but seems to have gotten worse. Maybe the wife is painting more under glaze on
  3. I am making plates with plainsman clay and the ^6 clear glaze. The problem I am having is with the under glaze painted on the rim. The clear glaze does mot seem to get thick enough and has a sandpaper like finish after fired to ^6.I dip the plate in the glaze, tied a longer and shorter dip time with no difference. The rest of the glaze on the plate is fine. Any ideas how to solve this problem.
  4. I place mine in a pillowcase and then onto the cement floor. Move it flip it a couple of times a day until it is right. Manage 5 gallons at a a time.
  5. The new belts solved the problem and cured the belt squeak with some spray belt dressing.
  6. Still wonder what HP the motor is, there is no label on it. Would be nice to know so I could compare or know that the next wheel has a larger motor. Guess I would just go with a 1hp model of wheel
  7. The drawing is wrong because if you pull strait vertical your pot would have tapered sides . That drawing does not represent a spinning wheel. If the wheel head or shaft was bent then the drawing would be accurate.
  8. The new resistor came today, replaced the 22watt with a 50watt chassis mount. Mounted the chassis mount to the aluminum case. Plugged it all back in and it is back up and running. Thanks to everyone for the advise to steer me in the right direction to find the correct part. Now to see if I can throw 15 lbs of clay, if not I see a Brent C or CXC wheel in my future.
  9. Looking at prices of new wheels with some power to them because of issues with the new to me OLD pacifica. I can stall out my Pacifica GT500 when working 15 lbs of clay. Is there much difference between the Pacifica 800 and a Brent to justify the 50% greater price?
  10. I was given some clay to try that is cone 8-10. I am currently firing to a cone 6 with a cone 6 clear glaze. What would be my problems if I only fired this clay to cone 6 ?
  11. My current box has plug in for the motor and foot peddle. To reverse the motor you just move the plug over 1 pin. The unit is so old that the plug has a standoff below it made of wood. You can just see it in the pic. If I knew it was that old I would have passed on it but into it now with a new bearing and belts. New resistors should arrive Wednesday. .
  12. If I replace the board with a newer model will all the plugs fit. I guess the board is only a variable dc power supply. Might be able to have them send new plugs as well
  13. Was trying to work about 15 lbs of clay and leaned into it. The fuse blew so I replaced it and it still did not work. Opened the control box and could see nothing wrong until I lightly touched the resistor and it broke in half. This wheel is probably 30 years old and no one has heard of the Pacifica gt500. Better hope it keeps working as replacement boards will be impossible to find. Glad I can at least replace parts with my limited electronics. Will let you know if it runs after the resistor replacement. The plan is to cut the legs off the existing resistor and attach the new chassis style one. Wont even have to work on the board then.
  14. I found some at Digikey , the shipping was less than 1/2 in Canada. I ordered both of these and will try the one with the heat sink chassis mount style first. Thought for the $4.00 I would have the other as a spare and then never need it. The chassis mount was a little more but might be worth it @ $7.00 Liked your find better priced but I am in Canada. Bill your search results lead me to be able to find them at Digikey. Thanks.
  15. Thanks Bill. Would I need to mount that with a heat sink being that it is 50w instead of the 22w?
  16. Well now I messed up. Purchased a Pacifica wheel and find out it is a GT500. No one has heard of a gt500 including Languna. I sold my old Estrin wheel and now just fried the controller on the Pacifica. Have plates and wine goblets to trim but no wheel. Any one know what type of resistor this is so I can order one from Digi-Key. Dont really want to order a new wheel now.
  17. I saw a post you had in January that you purchased a Pacifica wheel   in 1972. I just purchased a Pacifica wheel probably about the same age. The wheel is a GT500, contacted Laguna and they have never heard of a gt500.

    I am trying to find out what hp the motor is and was wondering if you happen to know.

    Thanks   Ron

      ron, just saw this, my internet connection has been down. 

      i have not heard of it either.   where are you seeing the number?   i have a 400 and they also offered an 800.  could you be reading 5 for 8?  i bought it from the inventor who sold the business to laguna years later. 

      if it is on the motor, i would have to crawl under the table to see any numbers.   where should i look?   i can use a mirror to see what might be visible  underneath.    just looked with a mirror.  it is very hard to see the label and it is placed where it is almost impossible to read.

         i think i remember it was a half horse.

      Well just blew up the controller , yes it is a gt500. now I with I kept my Estrin wheel.


  18. Installed the new belts and it seams to be better, have to throw some more to see. The new belts are clear instead of black like the old ones. The wheel does not slip now but the belts squeak a lot from the motor pulley. I tightened the belts but it did not seam to make a difference, they sure stretched after the first run. The motor was a little out of line in relation to the belt, I aligned the motor square in to the belts and is a little better but still squeaks. The squeak is there when the wheel is running with no load so it is not a slippage issue. Does anyone use belt dressing spray on them like you do on the vehicle belts?
  19. I sure hope the belt is the issue. I find it will not hold a tension so it looks like it might be it. I use wood bats that are tight on the wheel and have always held the clay well or just lets go. I have been throwing for around 5 years and have never had an issue like this. . I contacted Laguna to find out information on the wheel and they have never herd of the gt500 They purchased the buisness in 94 and said it must be a very old wheel. I did not ask them about my issue, should have.
  20. I recently purchased a used Pacifica gt500 wheel. I replaced the top bearing as it was getting lose and noisy, the wheel turns flat with with no wobble. My problem is I can not throw anything larger than a mug and keep a centre. Bottom of items end up uneven, verticals end up higher on ones area, I trim and again it gets uneven. I have not had this issue on my old Estrin wheel and am at a loss. Just yesterday I broke 1 belt so I have ordered 4 new ones. Could the old belts be elastic like and start a speed pulse in the wheel? Would inconsistent wheel speed cause this problem. The wheel head is tight with no play, top bearing is new and the bottom one was fine and did not require replacing.The wheel appears to run true and flat with a tool just touching the wheel. Even a wheel head that was slightly out should not create this problem, it is like the bat will shift slightly but they are tight fit and it does it with all the bats. Hope the new belts fix the issue.
  21. Cracks are around the base to the outside. I have a sitter so I cant tell the rate of temp increase. I am trying a slow fire like I do the Bisque. 1 Hr on the bottom low then add the middle then add the top each hour. Repeat the same for medium then all to high.
  22. Both sides are glazed and fired on rollers to cone 6. Clay is plainsman stoneware and clear glaze with underglaze. Most sinks are 14" The cracks do not have the sharp edge so it must be cracking on the heat up. This is one that worked.
  23. I am making some sinks and find they break on the glaze fire and not the bisque. Is this because my glaze fire is a faster firing? bisque to C04 and glaze to C6 with a sitter. The difference is on a bisque I turn up each section 1 hour intervals and on glaze I turn on all 3 zones to low, then med, then high.
  24. Has Brent changed their CXC at all in 15 years. Looking at one that is 15 yeas old, right now but he wants to much for it but .I think he will come down .
  25. Anyone know what Hp the motor is on this Pacifica GT500. Cant find anything on the internet.
